I am looking to do a 13B swap to my FB which will be streetported and turbocharged. I would like to know the advantages and disadvantages of the different 13B's out there and which one you think would be best, keeping in mind I cant spend a huge amount of money on the engine. Things on my mind: does the 84-85 SE engine have any disadvantage to the FC engine? What are the differences in the different series? i am probably going to get a gslse or FC engine to save money so tell me about these 13B's. thanks.

If you are going to port the 13B, then you should stick to the 4-port engines (13BT and 13B-REW). See the porting links at the bottom of this web page:

The disadvantage of the GSL-SE 13B engine vs. the 13BT FC engine... no turbo, lol.

I think your "cheapest" option is to get a J-Spec 13BT (approx. $1,000) and run it with a Microtech LTX8 EMS (approx. $1,000).

oh i forgot to mention im going blowthrough turbo

would it be wise do you think to get an SE engine and get TII housings? or should i just get the whole TII engine?

What kind of carburetor and manifold do you have? That will determine which engine you need.

SE as in FC? Or SE as is GLS-SE? There's a water seal location difference between 1st and 2nd gen engines. Go with a full TII engine.
