who has had experience with them are they for real I ve heard some people say they are some say they arent are their numbers correct on thier stage II kit 540 rwhp they say at 19psi butt hey want 4700 dollars they are crazy on their stage 5 they claim 690 rwhp on an aggresive bridge port is this fore real isnt cheaper to buy everything seperate and build your own kit so one was selling their stage to kit used for 1899 if there number are true that aint bad but I dont think threse number are right and im sure they were in race fuel what does anyone know

 

cant read run on sentence i have this turbo and i like it

 

I would check with Davinci Motorsports about that kit, youll save alot of money . Plus i just think that it is totally unethical that they charge so much money for what they say is a KKK turbo, when in actuality they use a Holeset turbo you could pickup for a few hundred bucks. No saying the Holeset is bad, as ErnieT has made great power with it and ran impressive times, but lying about what turbo comes with the kit, is flat out rediculous and bullshit business.

How was that for difficult reading? HeeHee

 

I have the Stage 1 for my FC. For a turbo its size (very big) is spools damm fast and makes a lot of power.

Anything past the Stage 2 isn't meant for the street. Not sure I would even put the Stage 2 into an FC...

 

I had the stageII in my FC, I made FULL boost by 4500 rpm!

 

i have 15lbs by 3300 with the stage 2.

 

Damm that is not bad. How much power did you manage to get out of it.

But since I track the car, I need quicker spool than that.

 

You got to remember that this was on a S4 motor and I wasn't able to do a "complete" dyno run, we stopped at 5500 rpm due to boost creep Anyways, what track will you be runnning on that would require you to need full boost below 4000 rpm?

 

I just figured the Stage I would spool quicker out of the corners since its slightly smaller and more responsive. I think its more of a preferance than a "need", I guess

 

get the stage 6! that is bad ***

 

Yeah, I've ordered one for my FB...

 

So SR is full of **** huh?

Is anyone else on the board running their stage 2 kit?

 

The turbos is actually a diesel truck turbo used on the Cummines inline 6 or something like that, you can buy it for $400-$600, pickup a wastegate, have a manifold made (or just use an HKS manifold with spacer) and pick up the oil lines and everything you can make the whole kit for under $2,000 easily.

 

I would not say they are full of ****. ErnieT made great numbers with his Stage II FD, and the turbo spooled quick.

A bit overpriced for a Holset, for sure.

Not that there is a problem running big diesel turbos on RX-7's!!!

 

You NEED a boost controller.

As in say goodbye to your variable spring control!!!

 

What type of porting does he have, and what kind of number's did he put down?

 

I can't remember off the top of my head...you'd have to look for it.

But he was running 10's....

 

508rwhp at 19psi and a stock port reman.

 

Allrotor, I remember your turbo failed after a couple thousand miles if I'm not mistaken, am I thinking of a different stage 2 customer? Jim, did you abandon yours as well? What wastegate were you using Jim?
I've spoken with Ray several times, he was short with me, and was not interested in spending any time on the technical aspects of his kits, basicly, it was "do you want to buy one, or not" NOT>>>>>>>>>>>>>>>>>>>>>> Carl

 

i bought mine needing a rebuild. they charged me $890 for the rebuild and it is not ball bearing. i am using the big hks racing.

 

I keep hearing all these stories of people needing rebuilds after relatively few miles. I guess the turbo being oil-cooled-only is part of the problem.

But with the $$$ Ray charges for a rebuild, I'll probably just get a T62-1 or similar when mine goes

 

good choice. the turbo is bad *** but not when you have to rebuild it at a cost of a new t6x turbo.
