Get in touch with Maztune from Trinidad & Tobago. They're very knowledgeable with the engine you're querying about.

I'm currently doing the ST205 Toyota Celica GT4 conversion to my oem 4wd bj chassis. I've added the page with pix showing the start of conversion. My car is a jdm 4wd import.

Congrats on the ROM winnings with that very spicy setup.
Who's the M247 forum member that made you the Custom dual gauge pod/surround. I'm interested in acquiring one for my car.
