I own a 90 TII and have stock turbo for now and looking to upgrade soon. My current mods are...



Haltech E6K

Greddy fmic

Racing beat full exhaust

550/860 injectors

rotary works street port

port matched manifolds

blitz super sound BOV





Not sure on internal or external wastegate?

what turbo manifold?

what turbo?

If I go external waste then need advice on wastegate



Was looking at garrett gt25r turbo or some type of T3/T4

Any help is great

Stay away from t3 turbos, those are for small 4 bangers.



What is your budget, power goals, and whats the car used for? Do you car about lag?

my price range is nothing too much, maybe for turbo, mani, wastegate nothing more than 2000. Car will be used daily for the most part. I use the car for track and some fun drifting and also like it to be fast in a straight too. So a good all arond car and not have a lot of lag.



Another thing is that i see turbo manifolds for the fc and they are all t4 flanges how would i accomidate the t3? Some form of adapter plate but how would I go about doing this?

you'd have to have it build for a t3 flange however DON'T. As stated above a T3 hotside is TOO SMALL for a rotary unless its a GT3540 which happens to have a T3 flange. Keeping it under 2k, i'd say go with the HKS cast iron manifold, HKS wastegate, to4e or to4s turbo.
