Thread: custom Tri Y headers

3 INCH

Those big tube pictures are from Pito's car and yes its @ 2.2VE I think there were no big gains from the header alone!! IMO the modified SSAC its not up to par with the B18 tri-y header just for reference a car here with a setup like his would produce like 10 whp more with the header difference... For example Pito,s car had same pistons and stock IM and TB and put down 220whp and only difference was the header if you add up the Xcessive plenum and Q45TB that would be 230whp(proved) on Manuel SE-R So blacktrunk car its 12whp down... and BTW Pito's car trapped 108mph with the 220whp and Manuel 110mph with 230whp so the power was there...

With the Xcessive plenum and Q45TB, what runners were you guys using? N1 or the Stock? Was this also on a 2.0?

what about using the 4-1 header and modding that? 4-1 STAINLESS RACING MANIFOLD HEADER/EXHAUST JDM INTEGRA GSR/TYPE-R CIVIC SI B18 | eBay

Its the stock sr20ve runners not the N1 and I agree with Payu get the tri y headers and customize it.

Blackb13 whats your setup, with that price it would not hurt to try.

stock cams
ssac 2.5
2.3-2.5 crappy exhuast (soon to be 3inch)
thermo spacers
3inch intake with K&N velocity stake
my modded alfred n60 bin
gspec crank & waterpump pulleys
9lb flywheel

trying to figure out what to do next either header (jmr, Modded ssac, modded honda 4-1 or tri-y), n1 cams, or intake, or even the 4.4 final drive. or mayby a combonation of them.

coming from a guy that made a set of the custom secondaries. i think i'll do the tri-y now.

Try the tri-y and then N1 cams and 440 or 478 FD

Now everyone loves my discovery the Tri y header. And I thought it wasn't giong to work but it does
