Hey,

I've got an '88 TII w. 2500mi. on a rebuild...

MODS:

9:4 N/A rotors
street-port
ported WG
gutted cats
K&N drop-in air filter
RB FCD
MBC running 10psi max
Greddy Type-S BOV
Fresh 550cc injectors

I'm buying a 3" DP/MP combo this Saturday off another forum member for $100.

What kind of improvements should I expect in comparison to the gutted stock DP and Cat?

Will I get noticabley better boost response/power?

Hell yes. You better hope that wastegate port is a big one...

YESSSS!!! (haha)

That's what I wanted to hear. I ported to the limits of the stock flapper... I think I should be OK for the time being.

Just to make sure, you saw that my cats are already gutted? (so your hell yes is taking this into account, right?)

thanks

I don't... Most people who only port to the edge of the flap and slap on a 3" DP still get too much boost.

Well... I only have 2nd hand experience in the matter. A close friend has a nearly identical setup. Although he recently switched over to 750cc injectors, R-tek 1.7 and a Walbro. We both ran the *lower* boost with no problems, but he's now running a consistent 12psi (creeping to 13psi on a cold day in 3rd gear) with a similar MBC, ported WG and TMIC.

As soon as I install the DP/MP this weekend I'll turn *off* my MBC and see what the boost creeps to 'naturally'. I guess I'll go from there.

Thanks man
