Try this one again.

some reason it will not print it all on the first one. Just go to the single turbo and you will find more info.

 

You need a lot to break into the 10s.

 

I would think it needs to look something like this(or atleast vosko hopes so. )

 

T-78, Bridgeport, all the bolt ons, maybe some NOS to spool. Thats what I remember hearing.

 

There are many ways to get into the 10's, there is no exact formula as you could have a T88 on your car and still run 13's. Tuning, porting and what other parts you have makes up alot of it. I suggest it would probably have to be done with a big single, a motor with at least a big street port, and some good tuning.

 

According to the calculator at bracketracer.net for a 2900lb car to run the 1/4 at 10.39 (2/10's faster than your fastest Supra) you'll need 511 RWHP. Not too many people in the states put down that kind of power, but down in Australia and Puerto Rico people put down that and more all day long. Post this question in the Rotary Performance section and see what type of responses you get from guys like Rice Racing. I'd guess that at a minimum your going to need a fresh motor with at least a large streetport, running a big single (T78+), with a small shot of nitrous to help spool it. To do it safely I'd say go with the biggest FMIC you can get and run some H2O injection with a good stand alone ECU like the Haltech. Getting that power to the ground isn't going to be easy either, 6 Puck or better clutch, Kaaz LSD, and upgraded axles at the least.

 

Ask ari and steve from rx7.com both with 10 sec rx7's that are streetable... Traction will probably be your biggest problem.. Tunning as well.. Kazz lsd is a must I hear or you will keep busting your stock one with all that power.

 

all this buisness about a big single..jeez! Cmon guys, you know you can run a 10sec 1/4 on the stock twins. =) It might take a miracale but hey, it HAS been done.

 

ryan posted a pic of my car LOL

 

stock twin ten sec car???

lol

ill see that when santa claus gets out of it!

j

 

there is a stock twin 11.1 sec car around on the forum somewhere

 

2 things:

(1) don't forget a Mazdaspeed Power Plant Frame. Not an option--Steve-o kan runs one and it's holding up great after he broke his stocker (and welded it) numerous times.

(2) Vosko will *never* have a ten second car

 

I am interested in a T04s kit from XS-Engineering.
I think i am going to make a high ten whit that mods.
What do you guys think?

Whit other mods the turbo shall give 630 hp, if you trust XS engineering.

 

You are going to have to port that engine to no end to make enough power with the T04S .... and crank up the boost which is a given.

 

Ok, but the turbo are big enugh to dive at 10 sec?

 

ive heard a lot of crap going around with XS engineering and im not sure if id invest that much money with them right now. from what ive heard and the research ive done, the new garrett 35/40 kit seems to be very impressive. not one of the fastest spooling but definetely capable of high horsepower:
http://66.216.67.51/product.asp?0=220&1=340&3=612
to pull 10's your definetely going to need everything mentioned above, but some other things might help. Shaving some weight off and having some really wide rear tires, like at least 10" with some high quality rubber. to shave some weight off id start with replacing the seats and the exhaust system. on my car i was able to trim 60lbs from going downpipe back, and close to another 60lbs off of going to recaro shells that only weigh 18lbs a piece (profi sp-g and a racer sp-g). if money is no option you could always go amemiya or mazdaspeed widebody and shoe horn in some Fikse 17" or 18" x 13"s

 

I haved looked att the GT35/40 kit to.
But i dont know which of them i shall buy.
The T04S its a little cheaper and it seems to just as god as the GT.
I am gonna drivo on M/T street next year som the tyres are god enught.
Rx7store, is it smart to buy from them? They seems to have god prices.

 

I have bought a lot of stuff from Rx7store, they definitely have better prices than anyone else I can find, they are really busy though so you might have to call a few times to get ahold of them.

 

There is alot of stuff you will need for a 10 sec car.. Big single(to4E,S,R, Gt35/40 kit, T-88, T78, Any of the larger Turbonetics T series turbos), FMIC, H20 injection & possibly propane/methane(not sure which one), if you plan on running alot of boost 3mm apex seals, Large street port or a half bridge, Stand alone, PPF, Upgraded clutch, Kazz LSD, Upgraded axles, Upgraded radiator, DP/MP/CB,...................

There is a ton more that has to be done but maily small things. This is all i can think of off the top of my head and hope it helps. Ohh and look at spending anywhere from 12-20+k(US $) w/o the car included in the price....

i still need number one

i'm working on number two. my car should be moving under its own power today. i just bought rims for it 17x8 17x9 three piece

 

I don't think vosko will be running 10's on that 0 psi setup he's got there....

 

it will be running soon. break in period is gonna be horrible 1000 miles........
