which car do you think is better for road racing nx with det or a 240sx with a det
i wanted to ask experience road racers here which car would you think will be better suited for road raceing. i know sometimes a particular track favor certain drivetrains of cars i live on the east coast and wanted your opinion.
i was thinking the 240 because if i smack it against the wall there pretty cheap and easy to replace unlike the nx. which may not be rigid enough for the abuse.

240, RWD will handle the power of a DET much better than a FWD car. Plus the NX has been known to have cooling issues which can mean easy death for a nice motor.
cooling is a major concern for me that is one of the reasons i am asking around. i want a nice track car and a street car but if i destroyed my track car i want my street car to come in and put in some work. the suspesion does not need to be top quality ($ advanced de$ign) but i don't want no crap either it hasto be a coilover kit with camber caster adjustment.
I'd go with the 240 as well. RWD, more stability in corners and the steering response (you have to turn the wheel a lot more for the same results on a FWD).

The suspension options on a 240 make it infinitely more adjustable than any current set ups for an NX. RWD is better for a track too.
Just look at Nascar, they're RWD so it must be the best

Niether. There are no road race sanctioning bodies that I know of that allow forced induction swaps in the US.
That's not true, a DET S, B or P chassis is allowed to run in the SE-R Cup with NASA. There are a couple of turbo Classics running on the West Coast.
On a side note, I know you said US, but I think there's a Canadian org where a turbo NX is running.
From my experience, I'd say 240 DET hands down. The main reason is traction- if you ask the front tires to turn the car and put power down, you're not going to get as much as a RWD car.
Hmm. I did not know FI was legal for SE-R Cup. Learn something every day.
The caster question: The right kind of caster (?positive?) will *give* you negative camber the more you turn the steering wheel. Caster adjustment=good, and is why the GC plates kick ass.

Right, and it doesn't even have to be a DET. And SR-based motor is allowed in SRX, so you can come up with your own turbo combo, supercharge, super-turbo even a super-turbo VE; you just can't run nitrous.
For SR, you aren't allowed to run turbo or any variable valve timing motor unless it is the new QR in a B15 V Spec (which has a weight penalty).
Those rules are awesome! I wish we had something like that in Ohio. The reason I haven't turbo'd the car was because I was under the impression I couldn't road race it blown. I'll have to take a closer look at NASA rules and see where my SE-R would stand...
I think a det NX would be prone to overheating on the track if a front mount is used. As far as which car is "better" I think that is more a matter of personal preference.

My neighbor has an S13 240SX with a 180SX SR20DET/FMIC and has the same problems on the track (after a few laps). It is also a known problem for the 240. We've changed his fan and radiator since, but winter has come down on us and we won't know if it helped until next year (I envy you guys who can race all year long). We'll also making be a custom bumper vent and he has lifted the rear of his hood to allow more cooling (helped, but not much).
Anyhow, the problem is the same for cooling, NX or 240...
is he running with a stock bumper i find that hard to believe their are so many aftermarket bodykits to help out with cooling he doesn't have to put his intercooler in the front of the car.
Bob Armstrong, driving a GTi-R NX2000, won the Championship (Touring GT Class), by a wide margin, 2205 points to the second place Porsche, with 1740 points.
Armstrong Motorsport also won the Team Championship, in combined points with the NA NX2000, running in Touring, with Cindy and Jennifer Armstrong and Glenn Foote driving.
Awards banquet is this weekend!
Turbo car on the trailer, NA car in front:
So yes, I think it's obvious an NX2000 can be VERY competitive. Ultimately, I admit that a 240 does have more potential as a race car. RWD and a more sophisticated suspension can go a long way.
That said, 2nd place went to a RWD Porsche 968, 3rd place, a RWD 300ZX TT...
