where can I get a BIG BORE THROTTLE BODY?

www.e30zone.co.uk carry BBTBs' in their online shop. Anyone that has tried them has loved them. Send the guys that run the shop an email to see what if any difference they'll make to the US M20

you have one of those for sale? pics

Sorry man, I dont have one for sale.

[SA E30]

Yeah... think that came out wrong.

What I mean't is that if u have the head job, and the BBTB and manifold... it's gonna make more of a difference than just a head job...

The more air u can get into the engine the more power it's going to make (and of course this coupled with the right fuelling... but fuelling is determined by the amount of air)

IMO, u guys r wrong...

Of course modding the head u gonna get power, but u gonna gain even more if u port the intake manifold, and use a BBTB... u gonna have gains.

What we do here, is take a TB butterfly from a M30B35, dissasemble the TB, so it's just the housing... take it 2 an engineer, and tell them to bore out the TB, to work with this Butterfly... Works pretty well... ;)

We all use them...

SAE30 you know as well as anyoine that a good head (and cam) is better than a BBTB and a ported Intake manifold but one cost more than the other

he meant to say the intake manifold is the restrictive point, or bottle neck.

The AFM is also a chokepoint to address.

didn't you notice the ;) in my post.

You'll get more from a modded head than a modded intake manifold or BBTB. So i say the head is more important than both put together. But a BBTB or modified intake manifold shouldn't be purchased unless you have a properly modded head with good cam and extractors IMO.

Don't waste your money.

[digger]

because the intake manifold is restricted.

i remember seeing an advertisement in a roudel issue a few months back. I dont have any here at school so i cant look for you, but it was there. It wasn't a big player, some specialty shop. I'm sure you can check the list of advertisers online.
