Thread: Can someone identify this VE header *pic*

If your header is not smashed, it means your car is not low enough.

I bought Sam's JMR header, bolted straight onto my 20VE with 3'' catback, 3'' intake, 16VE cams it made 195bhp on a Dyno Dynamics dyno. Was a good fun setup but the header didn't outperform an eBay header at all compared with a friends identical spec car but just an Ebay header being the only variable.

I then changed stuff a bit, N1 cams replaced the 16VE cams, 2.5'' catback replaced the 3'' catback and the JMR collector was cut off, a new one made and welded on. The header specs were then: 2.25'' choke instead of almost 2.5'' before, primaries around 27-30'' length instead of 30-34'' before and outlet pipe being 2.5''. Primaries FYI are 1.75'' OD.

Here's some pictures, the primaries were shortened as much as possibly whilst still being able to get a collector slid on and sealed well.









Results being as follows, blue line being old spec and red current...



It's a much better spec now, top end is so much stronger than previous and extra low end torque is nice. Quieter exhaust is much better for trackday noise limits. I will probably go for higher compression pistons at some point (probably around 12-12.5:1) and look towards 230bhp.

nice save.

Jesus that modification dominates up top. Nice work!

Now THAT'S a good feedback....

worth reading that there's a not insignificant CAMSHAFT change there as well. got a link for the collector?

Cheers dudes, yeah the effect of the N1s can't be ignored in that increase.

The collector was custom item, the guys work is fantastic.

I'm really pleased with the outcome, ideally I'd have liked to get another 2" off the primaries but it wouldn't have been possible to get the collector on then without considerable work.

Look at this guy, buying up all my bits and actually using them
