As far as performance on that manifold would do for OUR cars, I wouldnt know. But just to give my tidbit of info, after I put some stage 2 crane cams in my old 420a, I didnt recognize very much power. However, AFTER i ported out my intake manifold (not something thats very fun), it was as if i was driving a GSX. Now on another note, on the old forums i was on, a guy simply ported and polished his out and he did not recognize a thing after doing it. So what I am saying pretty much is that porting out your intake manifold is more of a "complimentary" modification so to speak. Similar to a header or a catback in how it complements true power adding parts like cams, turbo, pistons etc. They help expel the extra air caused by the "true" power parts. So in a nutshell, parts like the header, intake, catback, p/p manifold do minimal when by themselves. But who knows, we wont know until somebody puts it on on OUR cars.

 

That really sucks man. I dont have 550. Ill be savin for months! Ughhhh. Why cant they just believe im goona send them my old one? Cause i will. What do i need it for anyways?

 

You're in Cali already. Why not just go down there and buy the manifold and install it right there?

 

wow.wow wow wow.... finally another power part from rrm for people too poor for the turbo.. after i hear an opinion or 2 on here from somebody who has it done to there car, i'll order the day i see a good review. well today is sunday, i will call RRM on monday and ask them a bunch of questions about this product, and i will post allthe answers on here tomarow night... i got a bunch of interesting questions....

 

This looks like it can take some time

This is straight from my manual, the numbers next to these parts refer to the ones in the picture. for instance, number 26 in the picture refers to the order in which take off AND the actual description of the part.

 

OK i got off the phone with road race... i asked if this manifold is included in the turbo kit, so its not a waste of money if u go turbo eventually, and the guy said no it is NOT in the kit, so thats good. i asked if its just the stock manifold, just ported and polished and he said yes. i told him i have other mods, like clutch flywheel, cai, cat-back and piggyback, and he said i should benifit MORE then the claimed 7-10 due to all the extra air already goin threw. i asked about gas mileage being better, and he said yes a little bit. and finally i asked the big one... WHERE is the power at.. and he said mid-range to high.... which is a GREATTT thing!
