I am on the look out for a 90 gt4 short shift kit. I am new to Toyota's gearboxes and I have found short shift kits for mr2's but not for a gt4. I know that some of the engines in mr2's are the same as in gt4. Are the gearboxes?? If not can someone tell me where a place to find one is. Sorry if this has been in a previous thread, but I couldn't find it.
