ok so tomorrow i should be porting out the wastegate and after that we'll start putting everything back onto the block. before i do so, i just want to make sure i do it right and ask some of you experienced members...
first let me fill you in on the car..
91 TII, full 3" exhaust (no cats), fcd, safc 2 (haven't gotten it set up yet), hks bov, removed all emissions

since the car has been down i have done the vacuum rack removal, had injectors cleaned, new throttle cable, couple new gaskets, o-rings, omp lines, will be porting wastegate, cleaned turbo, new fuel lines & fuel filter, and misc other non engine things.

now for the questions...

-after the wastegate is ported, approximately how much boost will the car be pushing?
-i currently am running with factory injectors and fuel pump. is it safe to boost the car at all considering that i have the fcd and exhaust? if so, what is safe.
-is it better to use heat wrap rather than the factory heat shield? should i use both? should i use the factory shield and then wrap the downpipe?

i can't think of anything else at the moment...

thanks guys

 

The car should be running stock boost after the wastegate is ported. It may be a bit higher due to the exhaust but the design of the S5 wastegate is pretty good so it should keep boost close to stock.

With your current setup, about 8 PSI is probably the safe limit.

If you still have the heat shields then put them in place. Wrapping with heat wrap as well would be even better.

 

aaron, you're the man.

i thought of a few more questions at work, but i'll be damned, i forgot :[
i should really write things down.

thanks again, aaron.
