Thomas, 98 was the first year of VVTi for the UZ. 97 and earlier had all the same heads. There was a cam change in 95 or 96 (dont recall which year) Any of the 400series VVTi head will bolt onto the earlier block as it the 430series VVTi head. The oil supply for VVTi actuation is the problem...

What all items are you feeding power to from the EFI Relay??? Where is your injectors and ignition power suppy coming from??? Sounds like you have injector power and ignition power coming from the EFI relay and it shouldn't it normally comes from the ignition switch or you could wire in a...

Check around with some of your local machine shops. To see if they know where to get it from. It is commenly used in the machining industry cause of its excellent build up and machining properties... You can try thier web site www.devcon.com or contacting them to see if you can find a supplier...

Matt, have you pulled the drain plug on that trans and made sure no water came out of it??? Looks like its seen a lot of sitting in wet rainy weather!!!!

Cant help you with a head, but Devcon Titanium puddy works great for port buildup work. Not exactly cheap, buy it works flawlessly..

Yes, it will stay alive for that for the delay period. Every time the IGSW is on then switched off, the internal timer circuit takes over to delay the shut down of certian circuits... Are you sure you have the M-Rel wire going to one side of the relay coil and the other side of the relay coil...

Ok, M-Rel should stay on for 3 seconds after IGSW signal to the ECU is lost. So being that your not even getting a full second out of yours, I'd suspect a faulty ECU.

Yeah, the bigger 1.06 A/R might be a better choice especially if you plannning on upgrading cams... I would still consult with Garrett directly about it just to make sure, but bigger is safer here forsure, less power but safe from possible over boost.... Not that it really applies to this...

.82 - .86 sounds about right but I would talk with garret directly to verify that selection...

here's the one I like best.. (back to the 4088)...

Nevermind, I just saw the link to config area of it.... Didn't notice that before...

I went back and played around with it somemore and I am liking the GT4094-R How did you get it to link me to your setup?

Thanks man... Worked fine through that link.... (strange)... Sounds great.....

Damn, I never got to see the video... It says the video is no longer avalible.... WTF!!!!!

My point exactly. Granted it will take 20psi to achieve it, but I'd rather build a motor to handle more boost and spin less RPM's then run more RPM's with less boost to achieve the same power... RPM is what kills motors.... Yeah, you could but the smaller piping is going to hurt you more in...

Dont know what figures you used for all the inputs but based on 500hp for a 4.0L with .55 BSFC and a 1PSI IC drop, the GT4088-1 would be the best selection but thats only if your taking it to 6000rpm... Going with the GT4202, the area that peak torque is falling into is in a lower eff. range...

John, you beat me too it... That is the exact link I was going to post... It is a very accurate and helpful turbo selection calc...

Yes, the sequence has to be repeated. The ISCV is a 128 step stepper motor so having 4 steps per sequence, it should take 32 sequences to go from one end (open or closed fully) to the other end. The TPS adjustment shouldn't have an effect on ISCV opperation. The M-Rel triggers the EFI Relay...

I've tried Dry Film on ceramic and although it is said to adhere, I have never had any luck with it either... I had a set of pistons from a SBC that were thermal coated and had dry filmed side skirts from the manufacture that were damaged and there was no thermal coating below the top ring. I...
