hey everyone hows it goin im lookin to get tuned in about 2 weeks changin out the 02 hosuing should i do the manifold while im at it....... is there a power gain with that or should i stay with the stocker its getting flashed and tuned to 21 psi .... if i do go with the mani what brand as well???? current mods are tbe, exeddy stage 2 clutch , 255 walboro fuel pump, hallman mbc, injen upper and lower intercooler piping and intake..... thanks

 

ported and swain coated, BR does em

 

what benefits for the above with a stock based turbo?

 

port and polish the stock one....but i w ould just leave it stock for now, its not gonna dramatically increase anything and most turbo kits are gonna come with a new mani anyways if you plan on doing that

 

Buschur proved with a dyno that porting the stocker is worth 5-10whp if you have a SS o2 housing as well as the 10.5 hotside. If you still have the 9.8, you'll either want to either get it ported out or swap in the 10.5.
