Hope you are putting the T-belt covers back on. Unless of course you like rocks and stuff messing up your cam timing.

eh... maybe. A friend of mine never had any problems. He ran without them for more than a year, and his car was no slouch. Pulled Z06's like they was bitches. It's amazing what a big turbo, an intercooler, and fuel can do for these little cars.

Next time you go anywhere near a gravel road , you'll say "maybe." I may or may not say I told you so , depending on my mood that day. Let's just say with open drive belts , it's inevitable. They are there for a reason , and in this case there is no point in them not being on....... I don't care if your friend jumped off bridges for a year and lived every time , you could follow him down the same road and end up with all your expensive motor work being for nothing , in less than 30 seconds. Just a friendly warning.

I'm not driving the car a whole lot right now... so when I start taking it out more, I'll put it back on. I'll take more pics of the inlet pipe later today, that one is hard to see what is going on.

That is nice man- is that intercooler for a Z32? How is that working for you? I have the same intercooler that I wanted to use and I was going to mount it in front of the left front tire. How did you end up running it forward of the radiator? What size turbo are you running?

Hey and what is the plus to running an external wastegate vs. an internal wastegate?

That car is quite the engineering marvel man- you really did a nice job. I bet its a total sleeper too-lol

Most external wastegates I believe are adjustable. While our internals aren't

The simplest explanation is no boost creep with an external , since the dump is a lot bigger. Boost creep is a big problem on highly boosted cars with small internal wastgates. You guys down with that or you need me to explain boost creep to you.........

yeah uh, I just asked that silly ass.

Hey Marc I see that you did away with your boost sensor and all the vacuum lines attributed to them- how is that working for you?

I forgot the quotes smart allic!


probably just fine since he has an external wastegate and the ECU or any other sensor has nothing to do with it

Talking

Well............NANA NA NA NA !!!!!!!!!!
Hey how the hell do you post pictures anyways? I cant do it- Balliztik tried to show me how once, but I still cant do it- maybe my gayass computer isnt capable of gayness like that- it sucks b/c I have to sent pictures via email:P


And as you know the wastegate (internal) isnt regulated by any vacuum going to the plenum. nor any electronic controls. Does he have the jwt ecu?

It's a MKIV supra intercooler.
The T66 does not come internally gated.


Boost creep sucks, and I like the way the external gares sound when open to atmosphere... full boost hits and BOOM! Loud as a mother.

does the t-66 mount up the same as the t-3? What about bypassing all your vacuum lines? Hows your driveability now? Have you done anything with the ecu at all? Did you happen to do anything with your vacuum canister or is that still hooked up to?

How did you eliminate so much stuff from the motor man? The aiv and egr and all the crap attached to the plenum? do you drive that everyday? How is it to start when its hot?

Sorry so many questions, but what you have done to your car is what Im hoping to achieve.
