Where did you get that idea? Higher compression actually raises the VE, which in turn increases the amount of air/fuel entering the chamber at any given time. Boost is entirely relative to how much air the engine is flowing. But thats still beside the point, because boost and compression ratio are completely independent of each other.





Aurosting, how about a complete run-down of your setup?

Anyone want to comment on the material the apex seals are made out of for NA engines?

I believe its the material the apex seals are made out of that isn't good for boost. Also aren't the rotors a different compression? I'd be more concerned with the apex seals breaking.

Actually i thought of that ahead of time , am currently using t2 seal and gasket just to make sure i dont kill the engine and yeah the compression of my n/a rotors are 9.4 and turbo ones are 8.5, i wanted higher comp ....am prettry sure the seals wont break for a long time as long as i dont abuse the engine .....too much https://www.nopistons.com/forums/pub...#>/biggrin.png

man i would recomend to change those 550 injector for 680 or 720 secondary. i had my gslse engine with 4 x 550 and stock S4 turbo and it was sputtering because was running out of gas at 10 psi maibe is not the case for you. but just a recomendation https://www.nopistons.com/forums/pub...>/bigthumb.gif

actually am planing on doing just that.... installing 2 720cc injector and at the same time installing a front mount intercooler and an after market down pipe, i still have the t2 stock one with a cat

You have an aftermarket turbo whats your point?





This is the funny part here: You have enough for 235-240rwhp safely, if using the stock ecu and stock static fuel pressure rate.



Do you know why n/a boosted engine have a bad rap? Because most people who do them do ghetto work, and almost always pop the engine shortly after

Dude dont get offended or pist am just saying





and am also taking precautions to avoid killing the engine

and yeah if you want call it want you want



ghetto work, amateur work, proffecional work





if it works it works

Aurosting

check the link out. It is cheaper to make a n/a turbo then to do a turboII motor change. Nice to see others turbocharging n/a motors. 9.4 rotors do not use as much fuel/air at a given boost # as does 8.5 rotors.

chuck

cool site dude

a complete run-down of my setup







1----non-ported 6 port 1987 n/a high comp engine "9.4 compression"(seals and gasket of a t2 for safty and yes it can be done)

2----t2 intake manifold

3----msd fuel pressure regulator with boost index

4----4 t2 550cc injectors

5---- t2 fuel pump

6----t04b turbo a/r 96 p-trim

7 ----took the stock back end of a t2 turbo housing and got it bored out so the t04 fits in perfecty and got the whole turbo ceramic coeted and i also get to use the stock waste gate https://www.nopistons.com/forums/pub...IR#>/smile.png

8----t2 stock down pipe with cat , no secondary cat

9----single 2.5 exhust with a 4" muffer

8----stock n/a trans

9----no power steering, a/c , and pollution pump

10----20w50 oil

11----ngk b9es spark plugs

12---- 4 puck bronz racing clutch

13----hks blow off valve

14----t2 hood

15----10 psi of boost

16----atkin one peice "wha u ma cal it"(dont remember its name)

17---- thats all i can remember off the top of my mind
