Info On Racing S6 Rx7`s

[M.C Ren]

after searching the motorsport thread i havnt found too much info on racing rx7`s and nothing really on my question above,

what are the costs of building a s6 rx7 track car compared to a gtr? (taking out the initial cost of the car) nothing crazy either, everything on a medium budget, good parts good tuning but calculated decisions.

lets say the equivelant of a gtr with a couple of hundred kilos shaved and approx 350-400rwkw

how quick can you get them around a track compared to a gtr?

and built by a good tuner, how reliable can they be (obviously taking very good care of it)?

also, how does the chasis compare for racing between the two?

is anyone racing one of these at the moment?

and if anyone can give me their opinion on racing rwd vs 4wd that would be appreciated aswell.

im not too familiar on rx7`s and rotary`s either so any information is great.

as much as i love gtr`s for a street car, it seems silly to throw money into 2 rb26`s

also if anyone knows, what sort of power and weight you would be chasing for that sweet spot for a competetive rx7 to keep up with quick gtrs and possibly, put a few in their place.

and dont get me wrong, their is no better car in my life then the gtr, i am a true enthusiest, just interested in some information on something different

starting with something like this for example

or these these 2

you get my drift

400rwkw 13B is asking for trouble, stick to under 300rkws

Handling wise is chalk and cheese compared to the fat GTR

There are still 10+ year old Production spec RX7s stomping all over EVO9's etc

They are arguably the best handling car to come out of japan

[Berk]

I don't think he is expecting 400kw. Just the equivalent power:weight as a somewhat lightened GTR with 350-400kw.

I assume this would be very close to 300kw for a RX7.

[M.C Ren]

Yes I did mean power to weight, but in saying that though, it seems odd that you can't safely go more then 300rwkw on a race prepped 13b turbo, in that case, what would be the pros and cons of switching it to a 20b turbo engine?

Will the eng swap make it in eligible for alot of events?

And are twin setups or single setups better suited to a track rx7.

I know this is a skyline forum but this is my home and I know there are a few rx7 fans on here

[M.C Ren]

On another note, so far yous are both telling me what I want to hear

[zebra]

Oh you go do 400 or even 800kws...just dont expect it to last.

the factory twin turbos are massivley complicated so everyone who can (rules) goes single

20B would be good, but expensive and rare these days, also heavier,

NA 20B would be awesome though Ala the Grand Am RX8s (youtube them they sound un-real) and they make 400+hp (flywheel)

Mate I have owned and race both a GTR33 and a S6 chook cooker. Both cars in basic Tarmac rally spec, the Mazda was quicker first tme out than i ever did in the GTR for a third of the price but to go faster you need to go single turbo or NA 20b both options allowed in the race series we run here in Tassie, over the years a number of people have run GTR's here but have found deep pockets are required to run at the front. The best thing about the GTR was the launch off the line but my chook cooker is just as good, they have a fantastic chassis for a race car. It depends on what the regs are for the race series you want to do. Like you I love my GTR and have had one as a road car for 10 years and its great. If you are looking to get into a chook cooker I have mine for sale as I have bought a new race car and I just dont have the space to keep all the cars I have.

[M.C Ren]

hehe you remind me of my old man when you say chook cooker, the only difference is when he said the word chook, it was about chooking something in the a$$ lol

when you say single turbo im guessing you mean single 13b? not sure if you meant single turbo 20b.

and yeah i am likeing this rx7 idea although at the moment its just speculation as i am overseas for a little bit longer.

how much are you asking for your ¨chook cooker¨if you dont mind me asking and what are some of the specs?

I too loved my R32 GT-R tarmac rally/race car and moved to an FD RX-7 as every bit of research confirmed that it was going to be more cost effective for similar end performance at both circuit racing and tarmac rallying.

As Jason points out you do give up time in a standing start, but depending on the type of events you want to do starting is only one part of the race.

Compared to a GT-R the RX-7 is a more cost effective car to buy in good condition and prepare the chassis, simpler to maintain, and is cheaper to repair both mechanic and body issues... providing the car is well set up by rotary knowledgeable people, and with the correct support systems for the power level you want you will enjoy good reliability.

I'm on the tail end of my RX-7 build and very happy with it... although had I developed my old 200SX or old GTS-t to a similar level of spend as my RX-7 the end result would no doubt be comparable in performance.

[Marlin]

You're negating to mention the inability of the GTS-t to perform at RX7 levels given the former's restriction of turbo allowances V the latter's.

(I'm speaking from a selfish tarmac rally side of things).

[t01-100]

Very true Woo, but from a circuit POV the fastest car within the TAS Sport GT state catagory at the moment is an big turbo R32 GTS-t and previously a very nice S14... further to RX-7s, GT-Rs and 911s.

The FD has a lot going for it and is perhaps the better choice, but I still have a soft spot for the those two RWD Nissan's.

[M.C Ren]

i like the whole tarmac rally type of racing, but would def be taking it to tracks.

what sort of costs are associated with building a reliable race spec 13b turbo engine, without including turbo, fuel, management ect.

as i stated before, i dont have a clue when it comes to rotary's.

and marlin, on the tarmac rally side of things, what sort of power and weight would you be looking at in the series 6 to be elegible and lets say, very competetive.

there is an RX7 racing in the MRA series with a chev in it

1.04's on slicks at Wakefield I think its best time is?

I love the shape of the RX7's series 6 onwards - just a rotor scares me for running costs!

T01-100 is the guy to speak to mate, he knows more about rotors than me, and makes the rules that allows circuit racing RX7's with big singles elligible to compete in Australia's best tarmac rallies!

Given the new rules of 300RWKW and basically as light as you can make a caged one (1,150kg?), they'll be untouchable. Unless you have a fit 996 Turbo.

thanks for that, ill send him a pm
