We did some more testing this weekend to find out what happened. When we were putting about 300-350 whp down something did flex inside of the torque converter and probably bent some fins or tweaked something. We hooked up to the lockup solenoid and did quite a few pulls locking it up manually in 2nd, 3rd, and 4th gear and it runs fine under full boost. I'm going to talk to a few torque converter builders and see if they can furnace braze one of my spares. If I can get something done at a reasonable price I may push on with the 03B.

And the 03B research will continue into 20ish psi land! Also thanks to my brother for pitching in halfs! He was just as curious what the 03B will take with the built converter and we haven't installed the drivetrain in his car yet so this will make the decision on his car getting a Level 10 converter or a 04B VET tranny. Saves him time and labor watching my car break stuff :) They are rebuilding it now so I should have it next week sometime, they also said it should be good for about 500hp now.

Had this come in a couple days ago. Not sure when I can get to installing it because I am in the middle of getting the Scion TC engine/tranny together for my girl and also installing new central ac in the house....




Not SR20 but still engine porn... This is what we have been working on the last 2 weeks. 04' 2AZ-FE all head bolts drilled/tapped/45mm inserts, factory mahle pistons, built to factory tolerances.

We have been putting in some hours after work to get er done. The Level Ten converter is in the car and we almost have the car completely back together now. We cut the old TQ converter open to see if anything was damaged from the flexing or whatever it was doing. The stator (cast aluminum wheel in the center) had some scrapes on the blades and we couldn't figure if they were from interference from flexing or maybe factory balancing?? The oring from the input shaft that goes into the turbine was torn up pretty bad so I would say it was getting pretty violent under full torque when it was prematurely locking up. Other than that the lockup clutch was in excellent shape and no hot spots anywhere. This is the factory torque converter that I have been using for 40+ thousand turbo miles. Total miles on the converter 174,000

I had an 87 dakota TC stator looked about like that it was from loose carburetor bolts making an intake leak. Got a little more and more noisey every day then i found the leak. I was not boosting though. Also what the hell is with that water trench on number 4?

Well the good news is that the lockup is rock solid and the brazed fins help on launch. It grabs harder on take off and we can tell on the shifts that it is firmer. Bad news is that the premature lockup still happens. We are guessing that something is loosing pressure in the trans on the pilot side making it engage under high load. It's not a bad thing as long as it isn't tearing anything up inside.... Before it would try to go into lockup under full load and struggle for 3-4 seconds locking up. Now it just locks up and goes. We are also going to force lockup using the AEM FIC6 output. Hopefully the trans will be able to hold up to shifting while locked up after 3k rpm all of the time on 20psi. We will play around with the exact RPM that it engages at so it doesn't bog us down and with it locked we will be putting down more power.

Level Ten converter installed @ 174,100 miles

Mileage at 175,500

We have the AEM locking up the torque converter at around 14psi now and it works great. The only problem we have now is traction... Been to the track twice and have made a total of 6 passes but cannot stay hooked up. I had one decent run but second started slipping the 225/45/17's shifting into second so I was peddling in and out of it. The first day we went out there I had 205/50/17's with very low tread, the second time I had 245/45/17's with about 35% tread left. So I bought a nice new soft pair of streets and my brother bought a set of 225/45/17 Semi-Slicks. Maybe we can get some traction this weekend. We will be setup @ 20PSI, 225 semislicks, locking the converter at 14psi and shifting locked up. We will also have more timing in it than usual since we are running E85. I'm not going to be happy until I see high 12's :)

Nothing big going on with the car, didn't get much better times at the track @ 20psi. Couldn't stay hooked up until mid second gear (pedaling it to keep traction) and I think the ignition might be holding us back past 16psi on top of everything. Going to play with Dala's Arduino code and build a COP system to see if that helps us any. Also running about 55% ethanol for the cold mornings, seems like anything below 60% content starts pretty well on 29 degree mornings.

Car is @ 177,000 miles

Rebuilt RE4F03B (5 disc high clutch) with shift kit @ 20psi now at 6400 miles
Rebuilt factory B15 00' roller rocker engine @ 14-20psi 16,050 miles

Happy new year!

8:30 PM New years eve we had a rear tire blow out in the autotragic and had to replace the tire on a bridge in 10 degree weather. Have no idea why it blew out like it did. Guessing something punctured it and it went low trashing the sidewall...

Nope... I had to call a friend for a ride so I could go pick up another wheel and tools. I usually carry all that stuff if I go out of town but she was in stripped out trunk mode for hauling crap.

Car is at 178,900 miles currently. I decided to get a OEM bosch rear O2 replacement so I can get the stupid CEL light turned off and also changed the oil & filter. I also noticed that the flywheel sensor has been unplugged for awhile because it was one of the codes I cleared out of the ECU... Guess you can run without a rear O2 and flywheel sensor without any problems :) As soon as it warms up we are scheduling some dyno time to dial in better timing. I was going through all of our dyno sheets and tunes the other day and noticed that I'm still running very conservative timing. I bet there is 30+ whp that can be added safely. We also started the Arduino driven COP setup using Audi coils and it worked outside of the car but I am starting over and building it another way before I actually install it on a car. Other than that nothing big has changed but burning off the front tires and blowing out the rears...

Spent last Saturday installing new suspension parts. I replaced the upper and lower control arms with the cheap ebay units. $78 for the lowers and $49 for the uppers. Also replaced the tie rod ends and power steering bellows. We used these before in JamesJVO car and I remember having a few issues getting them to work well.

The lower control arms: Rear bushing 2 bolt cups are larger than OEM so they don't really fit without enlarging the mount holes for more wiggle room and a BFH also helps.
The upper control arms: Left fits, right does not... Right upper will not fit into body mount cup and will have to be ground on both sides until it is a tight fit. Have to be careful not to get it too hot because it has a rubber dirt seal.

Right power steering bellow = Master pro K9474 (Oreilly / moog cross)
Left power steering bellow = Master pro K9358 (Oreilly / moog cross)

Other than that James helped do a tape alignment and now the car feels soooo much better. 180k miles on the originals was probably pushing it too far :) In the next couple weeks I'll replace all 4 tires so I'm ready for the summer. I'll also schedule the dyno for awhile so I can tune and get some more timing in it to take advantage of the E85.

Just took it on a 220 mile trip to pick up a new car. Got 23.1 MPG on E85 at 80 MPH. Another 1,000 mi and i'll have put 50,000 miles total on this car boosted.

Just picked this car up for $3000 and it is going to replace my 6 speed G20 that I'm getting ready to part out. The G35X will be getting something that rhymes with twin turbo :)

I think it will be. The Re5F05a in this car is shared with the Titan and QX56 so the weak link is the VQ35DE. Probably will keep it about 400-420whp on E85 until I save up for a set of good rods or figure out how to get the 04 ecu to work on a modified HR engine.

I'll probably post it in the G35 forums, but I could copy it all to the "Other cars" section here since it's of similar interest. Of course there will be Beers and BFH's!! But as we have gotten older and wiser it will be BFH's before the beers :) Still deciding if I'm just going to build a separate drivetrain in the garage or just gut this car and freshen up the original 124k drivetrain and put it back in... I already have the turbos for her, 2x baby Borg Warners with the new Nickel-cobalt-tungsten superalloy wheels. Just gotta order a bunch of other things. Probably won't have time to deal with it until mid summer since we are finishing up my brothers twin scroll G20 right now.

The autotragic is at 183,500 miles now. I have put 50,000 miles on it since I saved her. I'm going to use all of the good stuff from my 99' that i'm parting out to clean her up this summer. Matching hood, driver fender, 63k mile interior, 85k mile carpet, JDM glass headlights, bumper cover.
