"log style" manifold for t3/t4

[lowandsleekDSM]

Hey everyone, i was jus wondering for a friend of mine that is building a budget turbo kit for his `99 integra if a 420A cast iron turbo manifold for a t3/t4 turbo with external wastegate will fit his B series LS engine. I know the turbo manifold from a 4g63 will fit his engine, but im not sure about a 420A manifold. Any one have any info for this?

just cut the flange off of the stock manifold and weld it to the new one. most exhaust /machine shops will do it for $20

Well, a 420a won't fit on a 4g63 ( at least to the best of my knowledge), so i doubt it will work on his integra. Where did you get that a 4g63 mani would ft an integra??

Sounds a little ghetto to me. Even if the bolts line up i doubt the ports would match up well. if you're going to go that "budget" do like DSm36said and have tehm just modify teh stick intecgra manifold. Also if it's cast iron and you weld regular steel to it it will probably crack before too long and be useless anyway.

Simple answer: No.

The 4g63 will match up to the b series head but the ports are bigger on the manifold which doesn't really matter. Just like porting a manifold I guess. A 420A won't bolt up to any Honda series head. A lot of Honda guys use the stock 1g manifold with 14b/T25 for budget turbo builds and they work out decently. Problem is they don't make a lot of power at low boost like say a 60-1 would which is the turbo of choice for stock motor Honda's.
