Hi all,

Just want to know if anyone has used the forward facing plenums off ebay and what the quality is like?

Also was there many mods to get them to fit?

Would it be better to go say a plazman or a RIPS one from new zealand?post-42704-1196716965_thumb.jpg

That what they look like if your not sure what i mean any info would be great.

Thanks Guys and Girls

i have personally talked to the people on ebay selling this one he said the only modification is you have to bed the water pipe and showed me where on a pic. then about a week later he is selling the plenums with the modified water pipes. i currently dont have the money to shell out for one of these. a buddy of mine bought one of the jun ripoff ones from ebay not from pnt_performance and he said it costed another 1200 to have a shop modify it to make it work. its up to you if you wanna try it. i would personally buy from pnt_performance when im ready to purchase my manifold tho. unless the ausies have some proven aftermarket ones that are redily availiable and they know from expierience they are good.

Unless your planning on making 300rwkw from your RB20 then a front facing plenum provides no gains.

I mean it does give you minimal if any top end... But it has been proven time and time again that a front facing plenum on an RB20 actually hinders the response/what little low down the car has.

IMO your money could be spent else where.

Thanks guys,

I will be aiming for 300at the treads i did a head gasket in it and im pulling the engine out and giving her some forgies ive got a bigger hyper gear turbo for her and some nismo injectors and going to put tomei cams in it.

The main reason i want to get rid of the cross over is the space issue it looks neater and the pipes dont pass the engine twice the less pipe and bends the better.

I reckon the "power gains" are all ass dribble too, I just loved the bling factor and I wanted short ass intercooler piping and what not.

I can change injectors with ease now (not that I plan to change them often), and spark plugs don't require me to move intercooler piping, bov etc. Last but not least it looks the business.

Call it wank factor, Call it what you want. At the end of the day each to their own :cheers:

At least its not a claim from WA....where they get 220rwkw out of stock RB20DET injectors, and 200rwkw out of stock silvertop RB20DET turbos....

I was making 205rwks from stock injectors and AFM and you only have to read through a few threads here with people pushing 200+ from stock injectors.

Sure its not healthy hence me going 550's and a Z32 with the new set up ;)

Dont waste your time and money on a forward facing plenum if you ask me, there are 1000000 of people running the stock plenum with big numbers and no problems with clearance issues.

If you are going to run one then do yourself a favour and talk to Kemp :rofl:

Ku Engineering (Very similar to the one you have pictured)

and yes the bottom metal hose needs cutting and welding, I learnt that the hard way :rofl:

haha it lives, does it make noise yet..... stop posting and make noise.

LOL....Just gotta finish the cooler piping (waiting on my stainless pipes) then its time to wire the E-Manage and start the bugger (I dont think the std computer will like the Z32 AFM and 550cc injectors too much) :P

i personally wouldnt be looking at a plenum i would be looking for a different engine

any turbo u put on a RB20 to try and make 300kw is going to be laggy as hell

ive got a 2L sr20 making over 300kw and it still spools up faster then any RB20 making near 300kw

legend01 makes 301kw atw from memory using a GT3040 and stock cross over pipe

then again it is a rb21.

im using a custom top half (not a cut and shut) with stock runners.

1st off though buy a garrett or trust turbo, rather than spending the money on a fancy plenum.

    • FWIW the depth of the groove in the rubber pad is not super essential, the blocks are rubber and squish a bit. If you are worried an angle grinder will make a deeper groove quick smart
    • I mean, if you were to move the jacking points away from the original location, that is, away from the wheels and closer to the centreline of the car, then it will be more likely to overbalance and tip off the supports. Same as we talked about before. I was talking about moving for-aft. If the sill is bent outward or inward, then the car would obviously look unstraight from the outside. Hopefully that hasn't happened either. Again, you can do comparative measurements from the chassis rails to see if there is much deflection.
    • Can you elaborate what you mean with your first sentence? I meant move as in the bulge kinda seemed like it got pulled "outward" meaning it got pulled down and to the side with the jacking rail itself, so the load bearing bulge now sits lower than usual and is not level with the sill on the other side of the jack point. Either that or the jacking rail just got pushed in a good bit.
    • As well as being risky WRT tipping off anyway. Yeah, I wouldn't expect it to move. Just measure from the rear one to the front one on the good side, then measure that same length on the wrecked side. You will find the notches in the pinchweld, and the jacking pad. Just spray a spot of marker paint or something there.
    • but any other area than the bulge you are talking about will just cave in then? The front driver side is pretty bent so I don't know if that will work the way it is now. I can still kinda make out where that bulge is/was but it looks like the position of it also changed due to all the mistreatment? Hard to tell
