I am looking into this for a friend. he has an 4WS Prelude... i think its a 93 and it has the H23 motor in it. I am very familiar with the needs and modifications needed for turbo cars... but my question now is where and how much or mabye someone has one used.... looking for a manifold for the turbo for the H23 Prelude. if it is either Garret T3 flange or Mitsubishi. I would prefer a Mitsubishi turbo flange. Also does anyone know the limits as far as the motor in a turbo setup for this car in stock motor. I can add injectors and fuel pump as well as control... but like how much boost can the bottom end handle and for how long before serious damage results. Thanks.

 

The h motors can handle boost pretty well on a stock bottom-end if you get the right head gasket+tune because they have solid decks....i'm going to be helping a friend do a h22 turbo setup.....and we have a h23 that we were planning on doing a turbo setup also......

 

LOL.....i wish i had a rx7

 

so, after you guys had yer little talk on the thread.... where can i get a manifold? what are my options.
