hi, guys:

Anyone knows where can I get a T25 flanged Cast Iron Manifold for B18C1? Actually I already have 1 from HKS but in my country, I can not find a reliable ceramic coating company. So I wanna get 1 from US and have it jet-hot or ceramic coated.

Am thinking about to get a T3 flanged, then get a T3 to T25 adapter, Will this work and upset the fitting of the turbo charger, etc?

Thank, pal ...

 

Well if you have a t25 based turbo then finding a t25 based manifold should be the only choice. Here is a nice cast t25 based manifold made by Edelbrock.

You could have this coated before shipping it out to you. I would never run a adapter just because it is a band aid (temp fix) not a solution to a problem.

 

greddys are t25. is there a reason you want cast? just have someone make you one.

 

just ship the hks to a u.s. or european company to get it coated... why would you buy another manifold when you already have one?

 

I don't see a problem in running an adapter. It may cause some fitment issues since it's pushing your turbo out further. I have no experience in this so what I say next is just something I randomly thought of in regards to performance. Using a T25 to a T3 adapter may result in slower boost build since you're going from a small opening to a larger one (loss in velocity). I'm guessing it may be a negligible difference though if I'm right.
