As the title. I'm collecting parts for my blob sti. It's on the standard vf35 turbo. I've got a walbro and induction kit on it. I'm Waiting for japspeed to get the turbo back decat in stock and adding a 3 port.
Is it worth adding rcm headers with a Venturi up pipe at the same time too?

 

i made 353.9bhp on my blob wrx with a vf35 and 365 FTLBS,i run rcm headers with a venturi up-pipe (you must wrap them tho-i used magma wrap)

a similar car with same spec as mine apart from the headers made 333.6 bhp

both mapped by duncan on rcm rollers-duncan said the headers definalty helped my car make so much

 

i have japspeed ones on mine with avf34 and made 384.5 so i would say no

 

Really I wouldn't spend money on RCM headers,yours stock OE STI headers should be OK at this power level and beyond,if I would spend money then maybe on the get them port and Harvey Up pipe

Thanks.Jura

 

A lot of money for 20bhp

 

Speak to alyn at AS performance he can do a good deal on the headers, rcm just use the gt spec stuff and alyn gets them from the same place only sells them quite a bit cheaper, and the harvey up pipe is favourable over rcm venturi afaik

 

On brilliant. Thanks for all the input guys
