Re: intake manifolds for EA
I have run the bbm on my ea for almost 3 years now. It gives you a nice torque uncrease up till about 300-3500rp. I actually noticed slightly better high rpm performance as well, say 4600-5500.
If you plan on running the stock EA head, remember that it has smaller inlet ports then all the others, so i suggest you have the inlets port matched, or go another head. Well thats if you want the most out of the upgrade.
Also, one thing to keep in mind is that th EA runs 250kpa of pressure to the injectors. EF-L run 275kpa. Your car will be dumping in more fuel. Not so bad if you have a decent cam, but the fuel bill may go up.
Hope that helps.
