ok so im looking for parts for a rb20 some simple bolt on goodies that arent 1500 bucks a peice but are still of good quality ok so i was on ebay yes ebay like a total noob and found rb intake plenteum for 300 instead of the the going over top of the engine with the intercooler piping just going through the passanger side ive always heard internals and turbos you shouldnt buy from ebay but what about simple bolt ons like that oh and never get exhaust from ebay real raspy bumble bee sound lol

If ur talking about the Freddy intake manifold. Ur best bet it to get an Isis, brand .. most of the eBay ones don't really line up to great as far,as the ports go n most of us with a budget use the Isis cause its probably the closes one or best fit for the buck. Uless u buy the real deal wich is the greddy one but u be lucky to even find an used one for about 600+..

yea the isis only makes an intake mani for the rb25, they are not interchangeable. The knock off ones for 300 have horrific fitment and arnt really worth the money imo. Unfortunately for us rb20 folk, we have undertaken a genuine money pit of an engine. $1000-$1500 for a decent intake mani is about right. The only other option that may be somewhat cheaper is see if a shop around you can fab one up.

We make to order fabricated intake manifolds for the RB20 however, like previously noted they're going to run your $1,400. But, brightside is we include a 80mm throttle body with them so it offsets the cost in the bigger picture.

Turbo, injectors, tune... is the quickest power for the RB20 without going too crazy.
