Hey guys, I have a 1995 Acura integera GSR. It has a LS VTEC swap b16a head with a LS block. It has K&N cold air intake, Hytech header, crower pistons,rings,valves, and valve springs, it had titanium connecting rods, crower 403 twin cam, motor is high compression running a 11:1 ratio. It has a 2 step launch control. From the hole it redlined at 4500rpm the VTEC kicks in at 5500rpm and it redlines at 8500rpm. It got a 4puc racing clutch. A build GSR tranny. Limited slip diff. I was wondering how I could boost the performance of my car, and make it faster, But keep it all motor. It runs low 13s right now on the track.

 

Lots of things. I would start with the basic mods,

What intake manifold and size Throttle body is on?

is the intake a 3'' ?

Head ported?

what exhaust and size? 2.5'' 3''?

You can play with a different cam profile, a different intake manifold, a different header. a velocity stack instead of the filter, even go with ITB's and of course a retune.

 

Yes it's a 3" intake
And I have a skunk2 black pro series intake manifold. And a skunk2 70mm throttle body.
A 3" hyper medallion exhaust
No my head isn't ported but I was thinking of going 30over. So practically I set the motor up to run nitrous but I have NOT used nitrous yet in the motor because the Vtec pulls hard and I was afraid I would blow the motor.

 

I recommend upgrading to the ultra street and a 74mm throttle body! I'm going to retune my setup soon i just replaced my pro manifold and 70mm tb and tuner 1 cams to the ultra street and 74mm tb and tuner2 cams.

Also they have a plenium spacer for the ultra street manifold now!

Slap a ported head on there with those mods and retune I'm sure you will free up some good hp.

 

all motor b series is financial suicide...good tires like street slicks or R888's you have no idea how much good tires matter. 205/225 if you can fit it but that's overkill imo.

 

ITR/B16 LSD trans. 4.78 final drive. Huge bang for your buck improvement.
