Thread: Modified sr20ve intake manifold

Well couple of guys I spoke to with stock-ish motors feel like it's too much work to test the intake, since it will involve wiring up a different TPS plug and re-tuning their cars.

So it's going on my built motor right now. Best I can do is test it against a stock plenum at some stage.

Curious to see what happens. I'd be willing to bet you pick up some 5 or so whp from 6k on...

Yea, there was a thread on one neovvl forum from Polish guy who made aprox. 5hp from 66mm enlarged stock body and slightly ported manifold. Nice gains on low budget.

Nice, I want to see how this goes!

Hey @Doctor G, how did this go?

Gonna be a few weeks before results are in. Need to break in the motor first.

I like the idea, i was thinking of doing some porting to the ve manifold see what it does.

Well small update. Removed this intake this week end to have the elbow section made up. Went back to a stock plenum and tb and the difference is night and day. VERY noticeable loss in power compared to the modified intake. More difference than I've ever felt from any header. I'm tempted to say 10-15whp on the butt dyno. Ad this is under 4700rpm so far.

Would def recommend this to anyone.

Looking forward to dynos. Also, did you cut the Plenum off in order to port the inside of the entries? I think if we welded to add material to get the entries larger you might make even more.
