RB20DET forward facing plenum
« on: March 07, 2017, 09:29:00 PM »
Anyone has experience/review to share regarding RB20DET forward facing plenum currently on the market?
I see there are a few vendors on TradeMe but not sure if they are from the same source (looks very much alike).

All I can say after going through a few different plenums during building my motor, is to just bite the bullet and get a decent one made. I did the whole cut and weld thing first, then bought a cast greddy style plenum. The casting quality is usually pretty average. Not sure about the front facing top halves that you can get, but id either leave it stock, or get one fabricated from scratch using the oem runners to make the flange etc. Depending on how far you are looking to push the motor will determine which would suit best.

although performance wise you would be fine sticking with the stock plenum.

I think it's worthwhile to go for FFP just to tidy up the intercooler piping mess (front mount case, obviously)
Wasn't sure if the trademe jobs leak or have bad mating surface etc...
Thanks guys

TradeMe ones from the luxury sports etc work fine IFF you check the mating surface and correct if necessary and pressure test for pinholes - (chrome plating etc can fix those if found).
