ya your goals are easily hit in our cars, 300 rwhp is no problem on a twinscrew supercharger and a tiny shot of nitrous.

Agreed, but an expensive route of obtaining 300 WHP.

If it were me, I'd go this route.

First I'd get the motor breathing as good as possible, cost without installation is about $2800 for items 1-5.

1) Head work: Porting Intake & Exhaust, Race Valve Job, Port Match Intake & Exhaust, Surface / only if needed.

2) Cams: 264/252

3) Header

4) CAI, Long Tube

5) Power Pulleys
************************************************************ **************************
6) Direct Port Nitrous, 35-150 WHP. Your stock internals will handle these numbers when progressively sprayed. So you could easily make more than 300 WHP, & what's even better is the WTQ output of a system like this. I'd go as far as saying that this exact setup on your 2.5L 323 would walk a stock Vette.

A DP nitrous system with all the safety devices would cost $1500-$2000.


Good luck.

I respect your knowledge on the subject of our platforms, and yes what you are recommending is a good path but if he has a decent budget I would just go twinscrew and nitrous.

I think i should do a tranny swap before doing this. I still got a Slush box on mine. So what i might do is swap the tranny then just save up get the stage 2. I think it fits more what i want. And i should be done

There is certainly nothing wrong with going this route, but lets take a good look at actual WHP output.

The Stage 1 is rated at 280 DIN, which is 276.2 Crank HP.

The Stage 2 is rated at 310 DIN, which is 306 Crank HP.

Though when you factor in ESS's drivetrain loss of 15% for the WHP calculations, things go downhill quick. Most would agree that a 17% or more drivetrain loss would be even more realistic on a rear wheel drive car.

Then of course this is all being done on a Dynojet dyno, the highest HP producing dyno out there.
http://forum.e46fanatics.com/showthr...465&highlight=

276.2 X 0.85 = 235 WHP, or at 17%....276.2 X 0.83 = 229 WHP
306 X 0.85 = 260 WHP, or at 17%....306 X 0.83 = 254 WHP

I got some experience with ESS twinscrew.
Stage 1 on M54B25 pulled 243whp on mustang dyno (would have been around 250 on Dynojet). That car was real fun to drive. Instant throttle response, flat torque curve.
I still think it's better option than messing with NA (mostly gains in the high RPMs) and nitrous (damn, my tank is empty again!)
