The only way you would see 20whp is if you go from running a stock DE header and oem cat-back with clogged cat to a proper header and free flowing exhaust lol.

If you guys have experience with intake manifold fab work I would work in that area before the header. The stock IM is a huge choke point that can make way more of an improvement. Best of luck! Its nice seeing more options!

Look closely!! into b18 big tube tri-y and you will get some decent specs of primaries for a header that will yield at least 10whp more untuned than any off the shelf header available for the SR20VE and you can take the same primary measurements and build a 4-1 with the correct 4-1 merge collector we have tested both setups and worked very well just for your information!!!

I was just be sarcastic. A 20 whp gain from a header on a stock VE? Not going to happen.


but if you are running the crappy stock one should be plus its on megasquirt

The megasquirt and Nismotronic ecu will make 0whp more than any stock based ecu under 8250rpm,

Where 95% of VE's on this board will peak 1000rpm earlier.

ASP doesnt have off the shelf headers for SR20's

The ASP headers around were ordered on a group buy made by Charles Dundon that used to work for ASP at that time!! And he made a few more on order and a couple more he sold to Greg!!

Sure they can build you a custom header for a SR20 but nothing of the shelf!!

I've seen these specs posted before but people never specify ID or OD.
