How do you do that? remove the hoses from the turbo and cap one side and blow throught the other?
make sure the tps is set properly.. sounds like timing is retarded.. When i first got my car running i set the timing to 10 in the manual but tps wasn't set right and was actually set at -10 to -15*
still ran a 16.3 at 83... fixed the timing 15.1 at 91..

check for vaccum leaks, also what is the idle? choppy, smooth, what rpm? Id do a fuel filter in case the previous owner ran crappy gas and clogged it up.

How I've done it in the past is to cap the compressor inlet on the turbo via a piece of rubber and a worm gear clamp, then get a pcv,abs, or other cap and drill a hole in it to fit a regular tire valve stem. Clamp the cap with valve stem onto the other end of your i/c piping and then pressurize with a bike pump or compressor if you have one. That will test all of your pipes and your i/c, but will not tell you if you have a leak at the manifold/throttle body area.

Alright just a little update on this issue.
Swapped out the injectors with known working stock 440cc injectors and the issue is still present. Turbo is still glowing red w/ stock heatshield and casual (no boosting) driving to and from work(15-20min drive).
I am still on the hunch its a fuel related issue, but the low vacuum is what throws me off. I tried making plans with my friend (ericshere03) to see if we cant swap his IC and lines out with some off of my car to test. Fuel filter will also be replaced.
If anyone has any bright ideas on anything else to test please let me know.

Timing all the way. Sounds to me like the exhaust cam has slipped and is letting raw exhaust out into the turbo. This is why it is sluggish to do any thing and you're seing egt's out the yang.
Also, sounds to me that if the ignition or the cam timing isn't off, that SOME WHERE there is a massive boost leak that you just aren't seing.
Take the IC to a radiator shop and have them pressure test it.

With the timing cover off and the crank set to 0 degrees BOTH cam gears are at the proper top positioning mark. So unless the pins arent in the right position i doubt the cam timing could be an issue. The IC could have a leak, but TBH he would probably end up buying a new IC from ebay that mounts up like stock rather then getting the stock one pressure tested etc. The only TRUE Boost leak i can think of would be the inner fender hose thats plastic, we cant see it easily and havent really looked at it. However the lower IC pipes do appear to be in good shape, but no physical pressure test has been performed on them.
How do you go about making a pressure test tool for our IC pipes?

Go to your local home hardware store and buy some pvc caps that fit into the boost hoses.
Take the turbo hose off and plug it. Take the throttle body boost hose off and plug it. Insert a valve stem into that plug. Take an air chuck attached to a bicycle pump or air compressor compress the system. Have a bottle of windex or soapy water near by and spray every boost connection possible. Also listen for leaks. I'm betting that since the timing is right on, that you have a massive boost leak. Extremely excessive fuel causes high egt.

Can you just hookup the pvc cap thats tapped w/ the fitting to the turbo and then cap off the 3000 pipe and test all of that? or do you ahve to cap off the lower IC hose that connets to the turbo?
One of the major boost leak cause is the cheap/15 year old connector that is on the throttle body.

yeah we replaced taht after doing the plugs and wires and intake side gaskets.
Hes going to perform a pressure test on it and see what happens.

as a matter of a fact the analogy we/he used for the firing order got mixed up, we got it as 16 35 24 instead of the proper order of 15 36 24. Hes going outside on his lunch break from work and testing it to see if thats whats causing issues.
He doesnt missfire and he has a steady idle... strange hopefully this is the issue.
