Default Would this work low 15'* mabey high 14s with a series II NA

All I am saying is hear me out on this I have an 1995 bonnie SLE with a series II NA with 205 hp and 230 ft lbs tq And according to my reasearch a 1995 bonnie has the option of comming with the series I supercharged with 225 hp and 275 ft lbs of tq and the supercharged version runs 15.1 secs in the qtr mile all I am asking is that if I can just add 20 hp and 45 ft lbs of tq to my car I should beable to run low 15'* in the qtr right? What if I add even more hp could I get into the high 14'*?

Not necessarily. The SC version delivers it'* peak hp and tq at a much lower RPM than you. That has a profound effect on launches, and in the end affects the 1/4. The SC engine also produces an incredibly flat hp and Tq curve, that keeps power consistent across the band.

You can transplant, though.

I would imagine that if you do mods similar to those of 95naSTA, you could pull off low 15s or high 14s (I'm leaning more toward high 14s). He has never been to the track with his car, but I think he'll be able to do it. When my project is done in a couple weeks I'll head to the track, which will give you a comparison between my dyno numbers and track times. Heck, I'll even weigh my car in race trim. We'll get this down to a science!

I'm aiming for mid 14'* with a healthy trans and a good launch. But we'll see.

I hope to eventually start modding mine, although I want an SSEi or SSE SC badly.

With the 1.9 rockers on an L36 I think you could expect mid 15s... don't quote me on that, though. If you want to be hardcore NA, you'll have to spring for a cam. If you wait a couple of weeks, I'll post some stuff that you might be interested in knowing.

With the 1.9:1 rockers you would have to have God give your car a push at the launch to get a low 15.
With the car stripped down(and I mean BARE) and a set of slicks you might be able to get a low 15. Otherwise the N/A motor won't have enough to get a low enough 60'.

There was a huge fight on clubgp about this. The bottom line is that it was proven that a intake, exaust, and rockered NA series 2 GT can keep up with a GTP and has run high 14'*. With that said, considering the Ser2 L67 is quicker than the Ser1 L67 you should have a close but victorious race against the 95 SSEi at the track.

Not necessarily true. The Bonneville is heavier, and the SSEi from 92-95 has a major torque advantage. A modified L36 might be able to keep up with a bone-stock and tired 92/93, but I doubt it would with a bone-stock 94/95.
