R33 Tarmac Rally - Engine Performance

[gtrtasmania]

Just wanting to know engine Kw + Torque figures for Tarmac Rallying.

Eg...... ECU + Panel Filter + Cat back exhaust (the same diameter as STD) + High Flow Cat.

Any help greatly appreciated.

Thanks.

GTR? or gtst?

GTR - 230/240rwkw.

As much as possible, with as much grip as possible

Need torque everywhere for tarmac rallying. Not peak power.

[T04GTR]

yeah. id say to be competative you want it all on by 3500rpm. so.. small turbos with lots of boost. 1.5bar+

Hi there.

GTR R33 V spec.

Yep.... as much torque as possible and early as possible.......too get you off the corner hard ?????

How much Torque can be had with these limited Mods ???

Thanks again.

You talking targa here or...?

[gtrtasmania]

YEP

Your better off with a N1 base i think arent you?

Fair difference.

antilag!

Step one.

Start with an N1 as a base car, as you'll need the N1 oil cooler. you CANNOT fit a non standard oil cooler, radiator, turbos, cams, anything really to a targa car.

You can however build a standard car into an N1 but you need to use all N1 parts. Not sure whether you've seen the price of a genuine N1 oil cooler, but you wont get much change from $11,000

So, start with the car that has everything you want already fitted from factory.

An N1 should do nicely.

And NO, you can't ran the Z-Tune. Targa Tas has banned it

[gtrtasmania]

OK......THANKS FOR THAT.

Would you have any idea of the expected Power / Torque figures of this setup ?

+ Weight of a R33 GTR V spec N1 with a cage fitted ??

Thanks again

[Bass Junky]

GTRs are heavy beasts. Even a fully stripped out race car is still going to way north of 1500 kgs including cage.

Power.... well as much as you can make out of "stock turbos" and "stock engine"

[Snowman]

Most of the Targa cars I've seen are making around 300-310rwkw's. No idea on torque figures but you would imagine them to be fairly punchy.

[R31Nismoid]

hehe "stock"

[PHaT MR30]

Steve Thatcher and Tony Alfords GTRs are incredible, they just have NO lag!!!

hmmm, it is possible to get it down to 1200kg there are r32 gtr running in that region in japan and the r33 seem to be around the 1300-1400kg mark

[R31Nismoid]

Yeah but using Carbon doors and so on might not be passable for the requirements

[GeeTR]

Outa interest, does anyone know why the Z-tune is banned?

[sav man]

Our R33 N1 weighs 1580kg (lowest alowed) and has 318 rwkw, can't remember tourque. If you run the N1 turbo's your gunna get lag (wich you have to run if you run N1 spec). But the N1 revs harder so you still get a decent powerband (we run ours to 8500, apparenlty the whites ran their R34 to 9000)

Spec M2 has to run standard weight (1540 kg) + 40kg.

So.......what does a stock R33 GTR rev too ?

How low down does the usable power come on ? RE : Lag ??

Thanks
