Hi peeps I'm new on here so first off hi!!!

I am going to be doing some upgrades to my focus rs mk1, I have done the norm bluefin, decat, gen2 Front mount. I am wanting to upgrade my turbo so I have a t3 equal length manifold with turbosmart ext waste gate, if I go for a gtx3071r will I need to get a remap before I can drive the car?? I am going to save up and get steel rods and pistons plus a jenvey plenum but wanted to fit the manifold and turbo first.

And help would be great!

 

you may be able to drive it off boost, but it wouldn't be great.
due to the turbo being so much bigger it will require different timing and fuelling throughout the whole rev/load range.

 

Sabre tuning will be your best friends
What sort of power are you after? As that is really quite a big turbo, especially in a FWD road car!

 

How much would it cost to get it mapped?? I'm in Essex but willing to travel.

 

I'm looking for around 400-450bhp in the end but got to get the money for inlet pistons and rods etc.

 

400- 450 can be achieved with a smaller turbo than that mate.
Sabre have done several at that sort of power (400) with a hybrid version of the standard turbo.
They are based near castle Combe race track. And are able to map the standard ecu.

I'd chat to them before spending out too much on fancy bits

Dont think you need a turbo so big for that power mate you would probably spoil the driveability. As said before sabre are the people to speak to and would be able to advise you what is best for the power you want. Do a search on the rsoc forum there is lots of threads about them and what there doing on there

 

Ok thanks for your help guys!!!

 

johnfrs hybrid turbo is the best turbo for a road focus rs

 

Also there is lots of guys running 400hp or over on internally standard engines mate, as said look on the rsoc forum

 

What power does a johnfrs hybrid go upto?

 

There is various hybrids around but most can make 400-420 with the right suppourting mods i think. The gt2876 is quite popular aswell, quite a few options you can have really

 

So if I got a JohnFRS hybrid would I be able to get 400bhp with supporting mods??

 

Yes. But there is a better hybrid out there now IMO.
Speak to sabre.

 

i would not take a garret.... take a borg warner efr!!!
i installed a borg warner efr 6258 but the original manifold not fits. so i have build one. i've taken a few pics.









all pipes are between 42-44 cm




















DONE












w/ Turbo





here is the first start up

and here is from 0-100 (in germany kilometers )

and 100-230

the efr spools very fast!!! i have between 2900-3200 the max. boost
