[B]If the RX7 is 100% stock I believe the S2000 should be a more or less even race for it (with maybe a very slight advantage to the RX7).

 

a 97 RX-7? that's either a typo, or this is imported from Japan..
an RX-7 is hellishly fast and are easy to modify to make gobs more power..rotaries imo are superior to anything out there today (reciprocating engines at least)..if more manufacturers built rotaries, the engine would be far more advanced now than what anyone could imagine..i'd take a 13B over a K20C..who needs camshafts and pistions and reciprocating parts over turbine smooth power..
i'd like to see the next 13B due in the RX-8 dropped into an S2000..the RX-8 motor will be normally aspirated and is overall very similar in terms of power/torque specs of the K20C..hp should be around 250 and torque about 153 lb/ft with redline between 9-10k..then turbo that.

Hey guys, my first post here - caught the RX7 thread and thought I'd put my 2 cents in. First of all I am biased but just with going by experience with the 2 cars I doubt you'll win that race. The only way you will win is if the RX7 isn't running right which is a good chance. When I got my RX7 (stock) it had a intercooler hose torn and I was only making about 2 psi - stock is 10. I was getting beat by cars that I knew I could kill - I got it fixed and it was a monster. Going by the numbers it's kind of close but like was stated earlier - race him from a light and hope he misses a gear and you'll beat him. If he has a few mods - watch out! Good luck!

 

I've got a mate who has a 1980 RX-7 whom is believes wholeheartedly that he can whip my arse in my stock 01 S2k....

As I haven't had a chance to give him a run for his money as yet, and thus I am asking the question, is there any real competition here? I mean the car is basically something out of the seventies!

 

An S2K would destroy a 1st and 2nd gen RX7 - even a turbo 2nd gen. A 93-95 TT RX7 is a different story though.

 

Yeah my friend has a 93 tt rx-7 and all I can say is damn. I have never experienced the s2000 in person but my brother has an nsx and he got ripped to shreds by the rx-7 and all it had was exhaust.

Id say you should just race him loose, get sup/turbo and then get even =]


Good Luck

 

If he is truly stock, meaning not even an exhaust, it will be a close race, and you've got a good chance if you can shift better. If he has an exhaust, he's going to be about 265-285hp and you'll just have to hope for a mis-shift. Any more mods than that and you'll have to hope he blows up

As for the 1980 7, I'm assuming the car isn't stock. It really depends what he's done on whether you'll beat him. Obivously, stock for stock you'll kill him, but if he's got a heavily ported motor (you'll know because the thing will idle very roughly), he could have as much as 280rwhp in na form. In that case you've got no chance, cause the 1st gens are much lighter than a S2000. It'll be interesting if he's modified, I think you should do it just to see.

BTW all, If you intend to signup for the Streets of Willow Springs (Socal) track event, please make your way over to http://www.wurthmotorsports.com and sign up. We've been holding off spreading the word about the event to fill it with as many S2000s as possible, but it's a month away now and we're going to have to open it up to all comers soon to avoid losing our asses . Thanks!

EDIT - And btw, no the drivetrain loss on a rotary is the typical 15 - 17%, not 8%. With the mods demon posted, I think the car would be making more like 300rwhp if it didn't have a new fuel computer due to fuel delivery limitations on the stock chip.

 

i suppose it wouldn't help any if i said my VR-4 (4000 + pounds) has never lost to a RX-7, but i had a S2K damn near hand me balls on a plater, and my VR-4 is moddified

on a happier note, RX-7's do break down, damn near as much mitsubishi's (as soon as my new tranny is in, the car is gone, and s2k is supposed to be here in november muwahahaha) well any way you go, good luck kick ass and haul balls

 

That's interesting, because at 1200 lbs lighter, even if the 7 had 100hp less than you, he should be take you. How many 7's have you raced? I would think you'd take the 7 in a short race from a stop, but it would be tough at speed. I would also guess the S2000 you raced was at speed?
