HP Estimate? (And upgrades, for TII)
Hey, I was wondering if someone could give me a rough estimate of what kind of power I'm going to be making with the following mods? My car gets out of the shop tomorrow, then I have to start putting miles on it to break it in.
1988 Turbo II Anniversary Edition
10 PSI
3mm Streetport by Marvelspeed
Heavily Ported Wastegate
Greddy Type S BOV
2x 720cc Secondary Injectors
Walbro 255 lp/h
Greddy Profec B Spec 2
Custom Intake
Custom 2.5" Turbo to Catback Downpipe
Stock exhaust
FCD
First thing I plan on doing right away is, as soon as Corksport releases their Turbo back full 3" exhausts (with silencer, jeez!), slapping one of those on, and I figure I should make alot more power after that.
What should I invest in after that? I'm debating between Haltech and FMIC.
Anyways, thanks!

A dyno test is the only real way to tell how much HP.
This is even more important with porting, as one shops street port, might give you 5hp, while another shops street port might give you 50 hp.
and a 3mm street port means nothing... perhaps you mean 3mm apex seals on a streetported engine???

Don Marvel has been known to do some really great ports, that open up alot of power, so I'd assume the HP gain would be on the higher side.
That said, what kind of estimate now? I know dyno is the real only way, but before I can make it out, what do you think?
