I just made a single turbo , with only the nesesary to made it.
It works perfect, I think that i get meaby 60 hp more that the standar turbos @ 10 psi.

Here is the list of the parts:

Single turbo exaust manifold
Garret tdo4
Hks 42mm wastegate
Pettit racing ECU upgrade
Custome down pipe
K&N 4" inlet filter
Turbosmart Blow off
Custome fitins betuin the turbo and the standar intercooler


Please post with your opinion

 

Have any pictures?

 

of course

 

damn bro, i think you need to upgrade the intercooler. But at 10 psi maybe your charge air temps might still be reasonable.

 

Hope you have better luck them i did.

 

Single turbo with a stock intercooler?!?!

 

Ah when you save up your money jsut get a new intercooler, and throw that stock one in the garbage where it belongs.

 

Would it be cheaper to just build your own turbo kit like this guy did?

 

I spend no more that $2000
I buy only the nesesary , I have another RX-7 with all
But this one is a proyet to confirm that a single is better that the original twin turbo one

 

On the Pettit ECU? and Stock IC??? Oh man why?

 

Wow, I didn't realize we have rotor heads down in South America too. I bet these cars are even more rare down there.

 

I have 3 of the 6 that mazda brings to Chile

 

Wow, seriously man, thats just asking for trouble running the stock IC and Pettit's ECU. Don't wanna sound like an *** but I bet there's a lot of other stuff you shortcutted too.

 

Well, when i was in chile. I really never ever saw a Rx7. You had them all stored in your garage .

Upgrade the intercooler , slap a wideband and see if your afrs are good.

 

ok men , i will
I race last nigth with a lot of cars and it runs very hard an well , I'm very happy with the car , I hope that soon i will upgrade intercooler

 

Hoe much were you boosting? 10psi?!?

 

I have a peak of 11psi at 5000rpm but it get down to 10 to 8200rpm
The only problem that I have in this moment is that the lower intarcooler house , don't resist the pressure , so Im going to change it tomorrw.
