I would like to know if any one has used a RSM T.B. for any ecotec? Was there any noticeable difference?
Is there two different sizes? 58mm or 62mm. I found one at a good price but he says it is a 58mm. What size is the stock?
RSM = crap. Even if you buy it from somebody else.

bad experence or what reason ?
yes there was a noticeable top end gain which is magnified with boost
for ppl who have measured them they actually are 60.1mm
Not all of thier stuff is crap, however every single post from some ppl is stupid

Yeah could you remind us how fast was your RSM supercharger? Never ran right last I know. A company that advertise 62mm Tb and sell them at 60mm are screwing people. You got caught and will never admit it cause your ego is bigger than your brain.

i'm not looking for a bashing party, i just wana know opinions and experiances.
RSM sucks. get your tb from somewhere else. or have your stock tb bored out

I had my stock TB ported to 62mm and an K&N intake. It increased the throttle response pretty well.
Where do you take TB's to be ported?

Portage, MI
at your local machine shop....at mine they said it would cost about 85 -90 bucks
ya i got mine done at a shop in town.
did they cut the new plate for you also? do you have any pics?
ya they cut a new plate. i have a close friend that works at the shop so i got a pretty good deal on it.
Im at school right now but ill try to get some pictures later tonight after i get off work.
the machine shop I went to didnt want to taper it down and the fly and widen it again to fit the intake manifold opening so I said to hell with them and hello to reveco tb. If you have a straight thru 62mm it is basically a waste. reveco is 69-60-62 I believe. All about Air Velocity baby.
I've been using
this one in my cressida for a couple years now with great success. Maybe you'll like it too...

Yeah I know but it was what my 2.8L 5m needed for the tubular intake and 9k cams. Stock TB was 60mm and WAY too small for a revver like that. Just thought I'd toss it out there...
