510SC300

Just picked up my 92 SC300 w/ auto tranny last night. Most mods already done were for show so the engine has not been touched but I plan to start on that as soon as I get all the funds together. I've been a Honda guy and now have switched over. I read thru the forums and used searches but could not find the right answer.

Will a Toyomoto header from an IS300 work w/ the SC300? Considering same engines, I was more concerned about the differences b/w OBDI and OBDII and any issues I may run into if I decided to install them. I found a used set locally at a good price and hope to pick up soon. Any advice?

The is300 header would probably need modification to work. The upper part should bolt onto the head, but the issue is the downpipe section. The sc300 manifold has one pipe going into the catback whereas the is300 has 2 pipes that go into the catback.

Not sure about the obd1/2 issue, but if the is300 header has more o2 bungs than what the sc300 has, then you can just get a plug for the extra bungs.
