not a great deal it seems. look at a matouks vl engine bay below they use a stock vlt plenum with a pipe off the side and they run weekly 7 second times almost and are the fastest guys out there so im sure its more than enough for what you want. might be worth saving your coin and sticking with the stock stuff.

you could low mount a 35/40, to4z, or get a good turbo builder to build you a custom turbo that will serve your purpose Or if you high mount it the options are endless depending on the depth of your pocket

From one sleeper to another, check out my ad in the advertisers section. And yes a no hole piping setup can be made to suit Ps and check out the dyno sheet for back to back results Some original photos have not been recovered yet.

The stock inlet with front facing pipework does look like crap though..

From what I've researched so far the best result has to be the jpc plenum. Me personally id stick with the standard manifold and just get fab work done so it becomes a front mount.

what do you mean by best results? If you're talking flow rates it's not the JPC plenum, and if you're talking MPH it's also not the JPC plenum.

Yeah bit his mate said JPC was the best? Basically it depends on what you're after with your car... If you like the RAJAB plenum, you're keen on a bit more low down and maybe (only slightly) less up top with the standard runner length, then by all means go for the RAJAB. If you like the JPC and are willing to sacrifice a little bit low down for more top end with the shorter runners, go for the JPC, or have a chat to Ariel (ISL33P) Custom Plenum Creations who seems to have a lot of knowledge on inlet manifolds, and also who has back to back testing showing the improvements by fitting one of his manifolds..
