Since I put my GT40-88 on my 1JZ, the car has been getting laggier and laggier. First it hit full boost around 4200, then it started going up, and up, and up, until I wasn't hitting full boost until about 6500rpm. I knew something was wrong, but could not find a leak anywhere. Then for...

I have this really weird problem all of the sudden. I started my car, and it was sitting idling, when I heard this intermittant clicking sound. I tracked it to the fuel pump relay clicking off and on for some reason. I also noticed that every time it does, my fuel pressure drops and my motor...

YAY, I'm so happy! This afternoon I finally finished the GT40-88 swap on my 1JZ. Took me almost exactly one month. First, what was done: -Motor was opened up, and main bearings were clearanced, and replaced. This eliminated my cold start knock I had, I'm very happy. -800cc injectors were...

I hate to say this, but I don't know the fluid capacities of my motor :( I know oil is about 5L, and I think coolant is about 4L, but what about the power steering system, and hydro fan system? Pretty much all that's left with putting the motor back in is to fill it back up. I looked in...

I have a set of Yokohama AVS Sport tires on my Supra (255/45/17 in the front, 285/40/17 in the back). I'm curious as to how people have found they hold up on the drag strip. I tried them at the track, the first run I had NO traction, and just spun like crazy, but after that, they gripped...

I pulled my 1JZ to throw on my GT40-88, and decided to check the main bearings. 1-6 are pretty good with some SLIGHT marking on them (looks like a little debris got into them, but bearing 7 is trashed. Looks like it was starved for oil. I haven't checked the rod bearings yet. So, I need to...

I tried to put my BIC test pipe onto my JZA70 today, and found that it was an inch too short. I was under the impression that the two cars shared the same exhaust? Or is is just the same from the cat back? Whatever it is, my stock cat is about 12 1/2" long, while the test pipe is 11 1/2"...

I didn't invent the concept, I just built the device. I needed a way to keep 2 kegs worth of beer cold for 10 days for a camping trip last summer. The solution? Cool it as you pour. I recently pulled it out of storage, as it's the last day of our classes on friday, and I am having...

I FINALLY got around do dynoing my car. Current mods include chinaman y-pipe, crower small core 272 cams, and HKS F-Con V-Pro engine management system. Here's the dyno: And now for the best part: This was STOCK BOOST. It crept up to about 12psi by about 5k, but still, stock boost. I...

No, I'm joking, it's plenty big :) Garrett GT40-88 with PTE .81 T4 hotside. HKS 50mm WG, and equal length manifold going with it. Now all I need is the snow to melt, and for it to warm up so that I can get this baby into my car. This thing is going to be FUN!

I'm pretty sure this isn't a repost, but if it is, it's quite possible the funniest thing I've read in a long while. http://www.need2speed.com/vb_forums/showthread.php?t=28790 Seriously, it's worth the read.

http://forums.beyond.ca/showthread.php?s=&threadid=168264 Not sure if any of you are from Calgary, but on a local forum someone made a thread about some RSX that smashed into his buddy, and drove off, just happens that there was another member that not only witnessed it, he took pictures!

I noticed that recently when boosting (16psi), in 2nd or third around 5-6k, the CEL comes on. I pulled codes, but I get a code zero. I know my ECU is bad, it just sits there to control idle and A/C, my standalone controls the rest. Do you think the CEL would be a knock up higher in the power...

I installed an XM satellite radio in my supra this weekend. I got a Pioneer GEX-P920XM (IIRC), it's a receiver that just plugs into the back of any pioneer headunit with a p-bus. I love it because there isn't some obvious "Steal me" box sitting on my dash, it's nice and stealth, and doesn't...

This evening I was wondering if I had the gains properly set on my amplifiers, so I pulled out my oscilloscope, plugged it into the amps, and ran a test-tone through the head unit. These things come in handy :) My old PG amp powering my front components had to be adjusted to a minimal gain...

I posted this over on SF too, but thought you guys might want to see this. I drew up a replica of the exhaust flange on the CT12A turbos in AutoCAD so that I could get some flanges machined up. I still need to get some prototypes made up to check fittment, but they match up almost perfectly...

I've been doing some research, trying to narrow down a good turbo that will get me around 500hp on 94 octane. I hear a lot about GT35s, but I did some research into the GT4082, and it looks promising. Has anyone run these on a 1JZ? Judging by the flow maps, 500hp may be pushing it, but as long...
