sup guys, i may be getting a '91 SER with a pulsar GTI-R swap in it. the mods on the motor include:

Nismo flywheel
ACT XTR4 clutch
Walbro 225lph fuel pump
HKS drop in filter
HKS 3 in downpipe

what would yall expect that to make on stock boost. what is stock boost anyway on those motors? and is it true the turbo is bigger than a t25? also, what would be some beneficial mods to the make more power, this car will be a daily driver. ill be happy with 220-230whp. the car also has Tokicko struts, Eibach springs, 21 mm Suspension Technics sway bar, Prof BOV, and DSS stage 2 axles, there is also a set of Pulsar brakes coming with the car :D thanks

it will make that power or more on stock boost. the turbo is a garret t28, it is considerably bigger than a t25. the stock wastegate is 8psi.

also you should search around, people tend to get grumpy with newbie posts...no offense

Stock boost you should see just above 250HP. Do you have a FMIC? What about cat and resonator? Those add up the ponies as well....


Good Luck. If you don't get those numbers don't be dissapointed. Just work on getting the car good a/f numbers and make sure you have enough fuel in that thing.

8 psi on T28 isn't going to give you 250 HP. Just like Will said...around 220-230 @ 8 psi. :squint:

the car still has the top mount on it, i believe he has a hood scoop on the car though. which brings me too my next question, what will be more efficient....top mount with a big scoop, or frount mount? i figure the top mount will provide good throttle response and adequate cooling, but the top mount will without a doubt provide BETTER cooling.

as far as exhaust, i have no idea....all i know is it has a 3'' DP. i should be recieving pics soon of the car. i havent seen it yet, its about 2 hrs away from me.

btw...NyceP26...what kinda front end do you have??

4-puck and Xtreme PP, Power doesn't matter, your tranny just broke...

I doubt you will make 220-230 whp on an 8.3:1 motor, you get those kind of numbers on a DE. I'd say 200-210whp.

And like goneturbo said, that clutch is way overkill. Hope you like changing transmissions.

GTiR will make about 230whp on stock boost with an intake and 3"dp. Maybe 220 at the least. A stock BB sr will put out 200-210whp stock.

don't get whp and hp confused...they are totally different.

don't know. I feel like my car is slow, literally. I would be interested if anyone had a dyno chart with that setup. I still havent dyno my car yet and still trying to figure the exhaust smell that engulfs the interior. dammit. oh well.

If you search you'll find a few BB dyno's of 200-210WHP pretty much stock. I'm yet to see a gtir dyno stock.

It all depends on what the car has. I think its very possible for that car to put out around 220+whp. Even though the motor is lower compression, it should still make some nice power.

I was able to put down 215whp on a t25/t28 hybrid at 6psi with a BB tmic, 3" exhaust, and pulleys.

As long as the car is running good, 200whp seems very do-able.
