This has prob been coverd alot. But my phones crashing when trying to search. Anyway

Am buildig a zetec turbo engine using some focus rs parts. I have a tubular manifold for the frs an struggling to find a gd standerd turbo but what power levels/psi of boost can theese handle in standerd form without worrying its gna go bang everytime me foots down as this is what am building car for.

Also what can standerd injectors flow safely an the fuel pump?


Cheers for any help

 

Not sure what is the max power for the turbo but know when guys are running there frs direct they run them at 22 psi.standard boost is 12 psi on frs.

 

So ur saying a standerd turbo cn run 22pis?

Am after a roughlt a max bhp limit before i commit to wich turbo i will use


Cherrs

 

I would say so mate think there max is about the 300 ish not 100% but sure it's around that.
22 psi is fine there are guys running them with that.

 

Cheers

 

My car made 320 at 23psi running direct on standard turbo so it's doable ideally tho get a Johnfrs hybrid 500 exchange capable of 400+ still based on a gt25 too

 

Also mt car is running 360 with standard injectors and pump

 

when u say running "DIRECT" what do u mean?

 

It's when you disconnect the boost solinoid and have a pipe direct from the compressor housing to the actuator.

 

right, just like a normal RS Turbo

 

Yeh must be mate. You still looking for a focus rs

 

yea mate, but need to sell the fezz first
Nearly done a deal today but the lad wanted to much money on top and it was a bit scabby round the edges #0346

But im in no rush at all, she is on ebay and nearly 1000 people have looked at the add, someone must need/want the car

 

Good luck with the sale mate.
Just take your time looking for a focus as there are plenty out there and prices are low just now.

 

No. Rs turbo's came with an amal valve for boost control
