so i got the FMU rebuilt tonight, fixed my exhaust leaks. sounds a lot better, i finally got my 40psi fuel at idle, 90 primed. however i noticed what seems to be water leaking out of the v-band right at the turbo(hot side) def not fuel, its water/condensation.

on another note when i try to rev the motor it stumbles and hesitates. not a clean rev at all. MY GUESS is when i extended the TPS/MAF it threw off the readings the computer needs? i was told if i did a clean job(nice solder joints) that the resistance wouldnt be compromised. tps 12-18" extension, and the MAF is like 24-30" longer. only other wiring that was messed with was the secondary o2's....extended as well.

another theory is that the return line is too small and is causing a problem. i still need to get the gauges installed, theyre all bench tested and ready to go in, just got a new job and have been busy the past couple weeks.

please any insight is appreesh!

Well hey cl! It's been a while, new job, new house. But I'm back.

I got my sc400-T up and running. After a blown turbo, and a lil tweaking here and there I've finally driven her a few times. And it's awesome. I'm seemingly having oil temp issues however. I installed a huge oil cooler along with a oil filter relocation kit to try and alleviate the issue. Haven't put any highway miles on, but in stop and go street driving the analog autometer oil temp gauge reads 250*. I'm thinking it could be a couple issues, either I bought the incorrect sending unit for the gauge, the gauge is faulty, or I need an electric fan to cool my external cooler(highway driving would cool it better)

Another issue is the koyo radiator I had purchased I can't seem to get the correct cap for. Every stant cap I've got for it does NOT seal off the overflow tube. Soooo, when it builds pressure it pushes it into my overflow. And since my sc300 overflow has the drain/vent on the cap it just pushes out.

I'm in serious need of my LSD/3.26 pumpkin installed along with an alignment.

On another note my aem wideband reads 15/14.9/14.8/14.7 and never changes to any other ratio, getting a p008/p006 error code. It worked perfectly fine in my honda, prior to installing it in the lexus.
