Thread: New ssac header I bought fits Ve head perfectly

Yours were the original SSAC when they first came out before the downpipe was enlarged to 2.5". Your downpipe was custom made SS about 5-6 years ago. Take care of it, they served me well on my DE.

I see, i am theyr doing great. Got them fixed and all

Well the proof is there.

A couple items of disclaimer. I got my SSAC from a UK store and not a US store. My collector is 2.5" and not any less, It's exactly 2.5" ID.

Side by side with the stock SR20VE mani:


With the gasket from the stock mani, everything lines up ports and bolt holes:


Temporarily bolted to the SR20VE, slides right on no jiggling or drilling:

nice i wonder if they just reflanged em or what

Everything lines up badly on an SSAC. They do have ports that closely match the VE in size, mostly because the tooling got so far off the holes got too big. I run one but it's crap IMHO until you re-machine it to match the Hot Shot it was copied from.

The above would suggest you are wrong. There are 2 types and this is based off of there design. Not sure if JPerformance welds another flange on it or now, but look at my above pictures. Also note the disclaimer.

The bolts line up, but the ports on both headers I've had didn't. They were sloppy.

Not sure which one you have, but the one I have matches pretty dead on to the stock VE manifold that came on the engine.
