350Z Intake and an 135i dyno: Friday tid bits

Friday, June 4th, 2010

This week we had a clutch job on an 05 350z and while he was here we fabbed him up a custom short ram air intake. The clutch job was straight forward OEM replacement with a flywheel resurface. The intake is a 45 degree bend 3″ aluminum pipe, custom MAF adapter and a K&N filter.

Next we have a BMW 135i getting some power pulls. Modifications to this car are minimal but productive. A chip with a stage 3 map is the only mod performed to this car. The bimmer layed down a best run of  325 whp and 351 wtq. That is a gain of over 40 whp and 50 wtq compared to stock. This was the first upgrade on the list for his car and more are to come.

We are staying quite busy and we have a couple of big projects going on. Get your appointments scheduled now before it gets too late. There is nothing worse than having some money or parts burning a hole in your pocket, and then having to wait to get your mods done.

Lining them up and knocking em’ down. 11 cars in 5 days

Tuesday, March 23rd, 2010

This past week Batlground was working at full capacity. We had as many cars as we could fit in the building (14) and a few in the lot. By the time Friday rolled around we were literally running around the shop. On top of the long term project cars that we had been working on there was still daily appointments coming in. Everyone wanted their cars back for the weekend. I would too, it was an incredible Atlanta spring on Friday and Saturday.

First of all the Prelude project is a wrap! The car was finally put on the Dyno for a break in tune after a wiring issue popped up with the oil pressure sensor and BCM (Body Control Module). It was also the only car not picked up on Friday. He did make it in today for delivery and the only person happier than our customer is his mom! She was very thankful to be able to get her car back. Thank you for your business and patience Brian.

We were able to deliver the 2000 Accord engine swap. Our customer was able to locate a 2000 Accord EX motor with only 11k miles on it! It really was like having a brand new motor to work with. No oily, greasy, grimy mess of a motor that I either have to clean or bathe in for the rest of the day. Pretty straight forward swap. Stock for stock, with only a adjustable cam gear and distributor to swap over. There was a minor set back at start up when the injectors from the new motor appeared to be frozen. We tried to free them up but ended up swapping over the old set.

A Nissan 240sx (S13) came in with a CA18 swap already completed. The customer had a running car but it was not running right at all. After a general inspection of the vehicle and its wiring, Justin was able to identify a couple problems in the wiring and set up. The MAF wiring had to be adjusted as well as the MAF being relocated further away from the turbo inlet. The ignition timing was off and the S-AFC 2 settings needed to be adjusted. Some tuning will have to be done before delivery of this car. It is already running a hundred times better though.

The MR2 with wiring issues was figured out and fixed. The final problem to be solved was a faulty fuel pump relay. That customer will be returning in the future to get some tuning performed when his engine management arrives.

A long time customer of ours had a small incident with a concrete barrier in his Supra. After the car spent time in the body shop getting new panels and frame adjustment it came back to us for some much needed general maintenance. We finished up all of his mechanical issues and it is now ready to move back over to the body shop for paint.

Monday and Tuesday we saw a Civic with clutch problems. We thought we had it figured out when we found the master cylinder leaking. Unfortunately the car returned the next day for us to find that the slave cylinder was leaking as well.

On Tuesday a Turbo Del Sol came in for some spark plugs and general inspection of the turbo system. The car had not been making boost, and we were going to do a boost leak check. Upon inspection though we found that the turbo was merely hanging on to the manifold and not tight. The waste gate was leaking badly too. What we saw next I have never seen before in my life. The outlet of the waste gate had been blocked off. A plate had been bolted on to the outlet of the W/G! Apparently whomever had previously owned the car was afraid that the open dump of the W/G would blow exhaust into the turbo inlet. How this D series motor and turbo survived infini-boost I have no idea. We were able to fix the issues of the car that night and made sure he got home. This Del Sol will be returning for some much needed tuning as well.

A 2003 Mitsubishi Evolution came in on Wed. to get some maintenance and performance work done. A set of GSC 272 cams, SuperTech valve springs and retainers, ARP head studs, Gates high performance timing belt kit, new OEM timing belt tensioner and pulleys, and a OEM water pump were installed. After the labor was completed Dan custom tuned the car with our re-flash software. At 20 psi on the stock turbo he was able to achieve 346 AWHP. Good for a deep run into the lower 12′s at the strip.

Thursday we brought in a BMW 540i. This customer wanted a new exhaust from the manifolds back. I had to fabricate a new “y” pipe on the passenger side due to a previous shops use of some 2″ crush bend tubing. This was a fun and challenging project. All stainless piping was used to match the factory quality. The “y” pipe section was 2″ tubing that collected into a 2.5″ section before entering the factory CAT’s. The CAT’s then exited at 2.5″ before collecting into a single 3″ pipe. I installed a 7″ round, 20″ long, Magna Flow resonator and that plumbed into the 5″x9″ oval offset in/out Magna Flow muffler. I was a little worried that the car maybe a little too quiet but after cranking it up I found that it had a really powerful sound while free revving. Definitely a more aggressive note than stock but not an annoying growl at lower to midrange cruising.

Friday I over booked us and we were scrambling to try and keep up. Justin had to take the day off and that really put the pressure on Dan and myself. Along with finishing up the BMW exhaust, tuning the Evo, and breaking in the Prelude-we had a Lexus ES 300 scheduled for some exhaust work after one of the flex sections in the factory “y” pipe decided to break in half. After fixing that section we found that the other flex had cracked as well. Our customer decided to come back another day for that one. We also booked a 09′ Subaru Impreza WRX for a down pipe installation. Dan and I tag teamed that one to try and give us some breathing room near the end of the day. By this point customers were showing up to pick up their rides and Dan had to get back to tuning.

All in all a great end to a great week here at Batlground. The weather is getting warmer and everyone seems to be getting the itch to get their cars started, fixed, or finished before summer time. Race season has already begun, our LS6/350z is up and running now, my KA24DE-T motor is nearly finished at Ball Engine Parts and Service. It will be  immediately assembled and installed back into the car. Look out when all 3 of the BG cars are tearing it up at the track and on the streets (legally of course).

SR20DET 350Z: What on Earth possessed them to do that?

Wednesday, March 17th, 2010

When we were first approached by our customer about this build we were a little skeptical. Why would you get rid of a proven, reliable, powerful, and technologically advanced V6 motor for a 15 year old, 2 liter, 4 cylinder? The answer was much more simple than we expected.

With the closest 350z/G35 specialty shop having outrageously high costs for mostly bolt on work , it is easy to get caught up in the idea that the car is expensive to work on and modify. If it costs over $300 to get a compression and leak down test from them, what would it cost to get an engine swap? In this case our customer is on a budget of under $15,000. That will cover the cost of purchasing the the body, motor set, all upgrade parts, and labor. Not too bad when you consider what you will have at the end of the day. A lighter, more balanced, and nearly double wheel horse power version of  the 350Z. Go ahead, go buy a stock one for that much.

Cost and Weight: The SR20DET motor in full stock trim including the transmission is nearly 150 lbs lighter than a VQ35 in stock trim with transmission. Add in that we are going to make 450whp and now you have twin turbos and manifolds, 2 down pipes, Y pipe, extra intercooler piping/couplers/clamps- the difference is even greater. Now factor in the cost of buying 2 of everything on the hot side. Your 450 whp VQ powered 350Z is significantly more expensive than the SR powered one. Now I know that there are single turbo kits out there for the VQ and I know they work really well because we have installed them here. The cost of those kits are quite a bit lower than that of the good twin kits. but you still are adding weight to the already heavier stock motor.

Balance: The stock 350Z has a front to back weight distribution of 53/47% and a curb weight of 3815 lbs. That puts 2,021.95 lbs in the front part of the vehicle. Subtract 150 lbs, all in the front half of the car, and you will see that the SR powered 350Z has a curb weight of 3665 and a weight distribution ratio of  51/49%. Nearly perfect. This will be priceless when on track. It will definitely be on track, this customer plans on entering the car in the Redline Time Attack series in the street tire class. After tearing it up on track he can drive it home too because the wifey is going to daily drive it as her commuter hotrod.

Power: With the plan to get 450 whp out of this car, our customer has a nice list of goodies that he wants installed. Getting that level of power is not voodoo magic to us anymore and almost all of it can be completed with off the shelf items. A Garrett GT30R turbo mated to a Mazworx turbo manifold, and custom 3″ exhaust will expel the the hot gases. A Meizure electric water pump and a Koyo radiator will help keep the motor cool. A custom FMIC and 3″ piping will be enlisted to cool the incoming air. GSC S1 Cams, and an upgraded intake manifold utilizing the stock VQ throttle body (yes the drive by wire one) add to the list of bolt ons. Controlling all of this is a combination of AEM EMS and a stock ECU. Our customer absolutely wanted to retain as much daily driver comforts as possible. Functions like cruise control, power steering and A/C are being incorporated into the build and the custom wiring harness. A custom set of engine/trans mounts have been fabbed up and the engine assembly is in the car. No solid mounts will be used on this build, as I made sure to incorporate the stock 350z motor mounts and the stock trans mount from the SR.

Justin will be starting on the wiring job soon and we hope to be able to fire this project up in the next week or 2. I am always excited to do something different and this fits the bill. We are already looking at another motor swap in a 350Z for a summer project, that one is gonna be a whole different animal, with a 700 whp goal. With the shop having a LS6 powered Z, this customer with an SR, another customer with a 3rd-still undecided motor swap, the RB26 swap Dan did back in 03′, and my “stock” G35 sedan – thats 5 different motors in a Z that Batlground has or will complete. Whats your flavor? I like mine vanilla with Reeces peanut butter cup pieces.

Batlground tuned S15 featured in MAY 2010 issue of Import Tuner.

Monday, March 15th, 2010

The S15 that we blogged about a few weeks ago that was ” So clean it’ll make you wanna smack your momma!” is a feature car in the current issue of Import Tuner (MAY 2010). See? Told ya! Just further proof of the level that this car has achieved. I personally have read the article and viewed the pictures, I suggest it for your viewing pleasure.

When push comes to shove, hit em’ in the knee with a baseball bat.

Today we will be broadcasting live as we make the final push to get the LS/Z tuned. Dan spent all day yesterday pulling the heads off the LS6. He had to modify the guide tubes for the push rods and adjust the rockers again. He stayed till 1:30 in the morning getting it finished. Thank you to Jason for his help yesterday, that allowed me to work on customer cars, and gave Dan an extra set of hands. After the motor was assembled again Dan was able to rev it all the way to red line. Previously it would stumble and break up around 3500-4000. We will see how it does under a load on the dyno. Broadcasting will begin between 12 and 2. Once again the link to view us is: HERE Please visit our gallery for all the pics of the build process and for all of our other photos.

The work doesn’t stop just because we are having fun.

Thursday, March 11th, 2010

Anyone that has been following Batlground over the last 2 weeks knows that we have been working very hard to get our new race car together. The LS6 350Z is the premier vehicle in the BG stable, it is by far the most impressive car we have ever built. We have logged extreme hours in the recent weeks just trying to get the car ready for shake down runs at the track.

That doesn’t mean that we have stopped working on customer cars either-its actually quite the contrary. Over the past 3 weeks Batlground has seen the most business since the beginning of the new year. Here are a few of the cars we have been working on and completed. Some of them you will recognize from previous posts, some of them are new.

First off the Prelude, thats all I’m calling it. I have completed this car and it is awaiting a break-in tune. We have a well documented history with this car. It tried really hard to beat me but so far I have prevailed…. so far. After getting this car started I let it down off the lift and it started making this HORRIBLE racket. I panicked and shut it off, lifted it back up and started it again. No noise, so while running I dropped it back down. As it lowered down it started making the noise again. Some head scratching ensued.  I was finally able to figure out the crank pulley was hitting the tension rod in the suspension as I lowered the car. I replaced the driver side engine mount and solved the noise issue. The motor sounds great and I can’t wait to see what the car will do on the dyno.

Next we have a 2nd gen MR2. Our customer had done a 3rd gen JDM motor swap and got the car running. It was not running well but good job considering the difficulty of working on that car in general. The car has some wiring issues and was running a mismatched ECU. The BOV needed its flange welded to the intercooler pipe, and we are installing a really nice downpipe and exhaust. We are still in the process of figuring this one out, but I know Justin can get it done.

The next couple of cars are getting various levels of work done, anything from general maintenance to motor swap. We had a 2010 Nissan Titan get a custom intake. A 2003 Honda Accord getting either a motor rebuild or replacement. There is a 2003 350Z getting a motor swap. We even had some time to dyno a FJ Cruiser, baseline numbers were 196 whp and 231 wtq with a factory 6 speed manual trans. I really look forward to doing some mods to that truck, as a supercharger kit is in the works.

We also had a visit from Todd @ AEM this past week. He wanted to check out the shop and drop off a new fuel pressure regulator for the LS/Z. We were able to get the car aligned this week and get it on the dyno. The car is having some issues tuning with a phantom cam trigger problem. Last night Dan also found out that the push rod/rocker/head combination requires modification to work properly. The first rockers we received interfered with the heads, these rockers fit in the head but require you to machine some material for the push rods to clear their guide tubes. That would have been really nice to know before we installed everything, but once again the supplier of the parts dropped the ball. We will get it fixed and we will have the car ready for the event this weekend.

Follow us live as we finish the LS/Z- we will be live broadcasting again on Friday the 12th.




LS6 350Z: Sleep is a luxury and highly overrated.

Tuesday, March 9th, 2010

Batlground Z

After an eventful Friday into Saturday work night, trying to get the LS/Z together and running, anyone who was watching via live broadcast is probably wondering what happened? Well I can tell you at about 4 a.m. saturday morning the car started and ran.

We spent about an hour longer on the car  before the starter took a dump and we were dead in the water. We accomplished our goal of getting the car running but we fell short of our goal of getting the car to the event. Dan drove his 240 instead and tore it up just the same.

Yesterday saw us work on it a bit more and get a few of the bugs figured out. Today we are going to live broadcast again when we get the car on the dyno. We are aiming for a 4-5 p.m. broadcast time. Stay tuned this week as we continue to get the LS/Z together.

LS6 350Z: Do or Die Time.

Friday, March 5th, 2010

Please visit Batlground Motorsports gallery for more pictures of this build.

Day 5 is here and the only thing we have left is everything. Dan spent over 12 hours yesterday getting all the plumbing done. We had hoped for more like 4-5 hours. Considering what had to be done though maybe we were a little too optimistic. With the power steering, brake, fuel, and accusump lines all being made from scratch-its not hard to understand why it took a lot longer. With that being said todays list still includes the exhaust, mounting the seat/harness, installing the wiring harness, mounting the battery, getting the alignment done, mounting the Moton reservoirs, start it up, and tune it. There are plenty of other small things that will pop up too. Hopefully this evening will bring a positive update and a sweet sound bite or video.

LS6 350Z: Run them H-O-S-E! Lay that (exhaust) pipe!

Thursday, March 4th, 2010

As always you can visit our gallery to check out more pictures of this build and all of our other projects.

Day 4 is under way and the LS/Z just left the shop. Dan is bringing the car to Andy at Performance Hose Distributing to get all of the power steering lines and fittings installed. Since this is a completely custom job-a custom kit must be made. Yesterday saw some tasks take a little longer than expected, so a little extra time was spent last night to try and catch up. Dan modified the fuel cell for the return and breather hoses, he also got the headers installed so we can get the flex sections and “X” pipe installed. Once those are installed we can make the turn downs and the exhaust will be complete. Justin finished the harness and it looks great. Its really amazing how few wires there are once you cut out all the non-essentials. The accusump is going to be a little more of a pain in the rear than we hoped. According to most amateur organization rules and all professional rules-the accusump and all of the hoses associated with it, that are exposed inside the cockpit of the vehicle, must be contained in a secondary firewall. It makes sense because you are going to have hot oil running inside of the car. If you were to hit a wall, another car, or even flip upside down you could possibly have a nice bath in 200 degree oil. Anyone up for some deep fried Dan? So we are going to move it into the engine compartment for an easier installation.

Once Dan gets back with the car, we can get it on the lift and make some significant progress. We will bust out the alignment machine and get it real close to perfect. Later we will take it to Gran Turismo East to have Kieran and the guys there make sure it is perfect.  The major goal for tonight is to get the car started. Once it is cranked we can check for any leaks in all of the plumbing, and hear how she sounds for the first time. Maybe I can even get a sound bite or video! At any rate, time is getting short and we have to buckle down to finish the job.
