I have a sleeved B20 block w/ JE 9.0/1 pistons, and eagle rods. I am currently using a LS head but might change over to a B16 or GSR head later on in the future. What would be the best Intake manifold and aftermarket throttle body to get for both a LS head and Vtec head?
Thanks

 

If you are going to buy the IM and TB before the head you are going to end up buying it twice because the bolt patterns are different on the B18c1 and on the B18b head.

 

Yeha I know that. I wanted to know what ones are the best because i am using a stock LS IM on my LS head currently. Im not sure if I want to go Vtec so I would like to know for further reference. IE: compare prices, etc etc

 

for boost edelbrock victor x cant be beat for the money

 

Ahh thanks. Does that go for both Vtect and not Vtec heads?

Thanks

 

for vtec heads the best would be a full race manifold. but those run upwards of $900. so the edelbrock is a more econimical choice for most.

 

it is made for both, but the same will not work for both...

Alright, Im not looking to spend that much for an IM as of yet since I just paid around that for a Full Race turbo manifold.

 

I second the Edelbrock Victor X. The huge plenum and short runners make it perfect for boost. A Edelbrock Performer X 65mm throttle body would be a good compliment.

Were you asking if the manifold fit both vtec and non-vtec heads? They aren't interchangeable. If you are thinking about doing an lsvtec, it would probably be wise to do it before you think about a manifold.

 

I know they are not interchangable. I havent decided to make my B20 vtec yet. If I decide not to go vtec then I will just get the IM for the LS head. Thanks
