Hi all,

Got a V2 RA with a polar performance chip and supporting mods.

I've just got my hands on a set of GT headers that require minor welding repair work.


Question is, is it going to be worth my time putting them on the car seeing as it cant be remapped etc? Will I notice any gains or is it going to make things worse?

Cheers

 

Trail and error mate,
Everyone's motor is different my only suggestion is to throw it on a set off rollers or get a decent wideband on it and see what it does, are they equal or un??


p.s got that cage in yet

 

Un-equal mate.

Havnt had it RR'd since I put the Pp chip, front mount or filter in so was planning to do that soon anyway to check the fuelling.

 

personally id put them on and get it on a set off rollers, you really wount know till then,
have you got a adjustable fuel reg?

Those chips were really designed to just have an after market filter and exhaust and up the boost by 0.2bar, so you may find with the fmic it may run lean?
have you got a walbro in it?

 

you could have the motor mapped mate
have a chat with esl, or jgm for that matter mate.regards to what these stainless heads really do. there not worth it.

unless your chassing really big figures, standard cast heads are good

 

Not yet, will be fitting a Walbro and adjustable FPR soon before I RR it.

Yeah, i'm aware of what aftermarket options I have, but for the moment i'm not planning anything silly.

 

i have harvey ported oem headers on mine

 

ive been told the unless chasing big bhp the cast ones are ok but arn't the aftermarket ones lighter witch will give u better performance in some way?
