So what is the story from the PD on the dillhole who took your car? I am really really glad to hear that you recovered it.

How tough was the Y-pipe install and did you also (I assume) upgrade from the stock DP? I never did myself because #1 I was too lazy too mess with the Y pipe and #2 I figured the car would hit boost cut non-stop in 3rd or definitely 4th. Dave

Noice! Heh. I had beaten Mazdaspeed 3 (100+ trap), a Z28 that trapped 97, etc. so I knew the old 1JZ could move out once it got traction.

Dude, thanks for posting your 1/4 mile results. I always wondered what my old car would run. I figured she would run 105 in the 1/4, based on the roll races (punch from 2nd gear, etc.) I had back when it was mine. I guessed right! Starting in 2nd, holy smokes! That's the 4.30 for you. Glad...

Glad to hear my old ride is getting some upgrades. I was never able to make it to the track, so I am looking forward to hearing what kind of ET & MPH you're able to put down. Dave

Congrats! Awesome results. What a monster that car is. I'm the guy from last fall's Supra meet in Austin w/ the 1JZ Mk2.

Thanks all. I will post again after I get a 3" DP. Not going to wrestle with the Y-pipe. Also, like I said, I checked the I/C and intercooler pipes for leaks. I am not sure how to properly check the other areas. I did have a nasty leak at my boost gauge fitting once.

Thanks! I have actually been driving this way about 1.5 years but only added the MBC a few months ago.

My near-stock 1JZ does not hold the selected boost level at high RPM. I set my MBC for approx. 13-14psi in 4th gear, but as I hit 5000+ RPM the boost drops by 1 to 1.5 psi. Is this normal? This happens in 3rd gear also. I pressure tested my intercooler system and pipes but realize I could have...

1.5 years so far....mine have about 75K miles on them now. Still boosting strong at 13-ish PSI.

Well, I fixed the problem using zip ties. Turns out that I had a boost leak right at the "T" connection which runs to my boost gauge. I had not bothered to zip tie or clamp those connections - argh! So whenever the boost went much above 10psi most of it escaped and did not make its way to the...

All in good time of course! What sucks is that right when I was completing my swap there was a r154 with jz bellhousing on craigslist near Austin super cheap, I think $250 or so. By the time I called he was packing it up to ship it to the buyer.

THanks for the tips. I will report back after I heat shrink them. I have been driving the car with the W58/1JZ at 10-11psi for a year and all is well. Like I said, I never drop-clutch start the car and try not to shift brutally.

I am going to closely inspect the packs this weekend, and either epoxy or heat shrink them. I drove the car a bunch last night, when it was cooler outside, and experienced the same problem. So the miss is boost-related, nothing to do with temperature. As for the W58, Mk2 Supra guys have...

Situation: Just installed MBC this weekend. Installed fresh set of NGK 6097's gapped at .028. The car misses badly as soon as she hits 11-12 psi, but only when the outside temp is in the 90s, as it is today. This morning, when the car had only been running a few minutes and the outside temp...
