RSM header!?!

[[DeVo]]

So i happened to see that RSM makes a supercharger for the N/A ecotec, and i was looking around, and what did i find? A header for the ecotec?!? RSM says that it's for either "normally aspirated or supercharged" but i'm not sure if they're talking stock supercharged, or their supercharged kit. I was thinking though that the exhaust ports and bolt pattern should be the same from the 2.0 to 2.2 to 2.4 even ecotec blocks? Someone let me know if that is wrong. The flange in the picture looks the same as the SCDyne to me, and for $260, that's not bad at all!

It looks like it will bolt up to the head ok, but the exhaust is a different story. Your definitely gonna have to move it over a bit.

That's true, but i would guess most people who are getting a header would go with a full exhaust too.. and the $200 that is saved with the RSM header could likely pay for a new exhaust to be installed right after the header.

the piping kinda looks small compared to the scdyne header

I'd find out how big the primaries are before buying.

Come on Vita, where is your 3" collector comment?

I am really tryin to hold off on a header, b/c i want to see what pan's out of psi-fi's TC efforts

[kazkillinger]

i just emailed them on what the sizes are lets hope they are BIG

[Jim Lewis]

I'd be very interested in this, too.

ok nice blast from the past but they finally emailed me and here it is folks

The primaries are 1.5" the collector is 2.25" If you have any questions let us know.

now i think the collector can be bored to 2.5 which isnt bad considering this header is only 260

thats the same as stock. Well so much for that. Id like to know about the crank pulley though.
