Since we're entertaining the thought of hybrid S2000's, what do you guys think of an STI (EJ257)

DOHC 16 valve turbo

Usage:

US Market Impreza WRX STi MY04~present (300 hp/300 lbt)

 

This is the best idea ever.

 

Damn, nice engine. What's the horsepower?

 

From the specs link:

# 400HP @ 10,000 rpm with stock street cams
# 245 ft-lbs torque @ 7500 rpm

 

[QUOTE=GPMike,Sep 21 2007, 11:03 AM] I personally cannot wait to get a hold of the Honda diesel and throw it into my S2000.

 

I've always wondered how much hp our cars would have at redline without VTEC...

 

It depends on which way you disable VTEC.

If you disable engagement, I don't think that the car will even pull to red line, because power with the base cam profiles starts to fall off after 6k. IOW, without VTEC the car would make less power at 9k than it would at 6k; Disabling VTEC would leave the car in pretty much the same class as older NA roadsters with 2.0l engines and fixed valve timing.

If you disable the base profiles, the peak power would not be changed at all, but idle would be rough, and torque and drivability at lower revs would be unacceptable, not unlike driving a car with a full race cam and no VVT.

Each of the two stages of VTEC engages cam profiles that are optimized for the speed range over which they operate, and will not work as well outside that range.

 

I mentioned that engine a few months ago. It weighs about 200 lbs while a naked f20 weighs 280+. It would be a dramatic increase in performance. But the cost is very restrictive. Might as well just start learning to use cad software and use the money to learn how to build the engine yourself. Bike motors are the closest production engines to f1 status. They can do many great things.

 

I'm sure turbo/supercharger would be a better setup

 

Better in what sense? Definately not performance. Maybe better on your checking acct. This thing weighs 80lb's less than our motor and makes more than 140hp and 60lb/ft of torque than our motor makes n/a. Supercharge that and see what happens . 1.3 litre busa's make 500hp np. 1000hp anyone?
