Like i said more pics up soon....

 

WOW that's a nice fit. Those 20's almost look like regular 18's. You mind sharing the specs of the wheels and suspension set-up. That combo looks very nice.


Slap on some 17" wheels and I bet you get a rwhp increase all by itself.

 

Yeah, suprisingly........ those wheels look nice.

 

HKS coilovers, 20" Iforged custom wheels, 20X11 pzero305-25-20s and 255-30-20s
20X8s front 255-30-20s Ralph

 

how did you fit 11's on the back without hacking out anything?!??! whats the offset if you don't mind. I'm gonna buy new wheels and want to fit the widest rim in the back without flaring for doing anyother kinda **** to fit big wheels on the back.also the offset for the front too. thank you.

 

looks sweet, didn't think 20s would fit!

 

Very, Very nice FD Ralph luv the setup and your taste. You'll be hearing from me after xmas for a LIM, oil pan and fuel rail.. I thought the gt42r was in the grey FD from rx tuner both very beautiful FDs and setups.. Since you have no mirrors on the blk FD is that street legal in Oregon?

 

I think the black car is a customer owned car, but the grey one is his. Very good numbers Ralph. I plan on bringing my T2 down next summer for a tune with you and chris from GT since he is the MT guy. I may be in town in a few weeks, kinda wanna stop by and check out the fuel system you run on the grey one. any ways ausome numbers...

then why are they saying the 668rwhp car rolls on 20's??


good looking car (BB)! had to go back to look at the shaved mirrors...definitely wouldn't expect huge power on something with such blingin' wheels, good work on the stealth, haha!

 

GZ is'nt limited to just one car you guys know. CJ

 

Because the 668 hp car does drive on 20s and was dynoed on 20s and no it is not a customers car it is a buisness partner.

 

Incredible looking FD!! I'll be looking forward to seeing more pix and some video soon.

Congrats on the numbers guys!! Tell John (PHAMSPEED) Dean says whats up!!

 

Hmm, make it reasonably reliable and I'll definitely buy another FD and send it up to you to build and tune.

 

Thx for the specs. The rear 305-25-20 has a diameter (according to tirerack) of 26.2". That's only .2 more than the 335/30/18's that Pettit uses on the Banzai Rx7.

 

A local racer friend of mine who , who runs low 9's with a street ported 13B making 485RWHP @ 20 psi boost on a TA45/51 has since changed to a full bridged motor and made 515RWHP @ 18 psi on the same turbo when he raised the boost to 20 + , his power dropped off although the turbines a/r is 1.32 , I still suspect the motor is being choked . He just bought a GT42 (non-BB) , any idea of the kind of HP he will make now ?

 

his motor's not being choked with that big a turbo, he's probably having ignition problems.

 

The GT42 non bb turbo should make the same HP as the bb turbo but the spool should be
different. I have never used a 1.32 ar before. How does it spool?

 

The 1.32 spools verywell on the bridge , he has over 300 HP by 5000 rpm.

 

congrats GZ. exceptional numbers. been a fan of your work ever since the article in BANZAI. good stuff.

 

Guys thanks for the support. I will keep everyone updated on the projects we have. Ect

What car is this in???a go kart?;p

 

Sweet,
Looks like the car is still pulling hard when you shut it of. With max tq at 7000 rpm there is still more HP to be had but you probably don't want to rev much higher. Congrats on the port job, you don't see many motors with a TQ curve like this.

We took it out on the road and the car is stupid. It lights them up so hard the car slows down even above 100mph. Were going to put in a boost contoller per gear and see what
we can do for traction controll. The car is a blast!!!

 

So it is possible to have too much power!
