I am very happy to see an active forum with plenty of information regarding Toyota's.
Unfortunately i have not been able to find much in the way of modifications for 18-RC engines.
I have a 1981 Toyota Celica Liftback, and i recently took it to the drift track for the day. It was fun but the car is very much underpowered and had plenty of body roll to match.
Can you all please give me some advice in the way of modifications to the 18-RC engine that have been proven to work, reliable and increases hp.
Another thing i was wondering is has anyone played around with suspension mods and found some good ways to eliminate lots of body roll and increase handling?
granted, if you have the funds, don't worry about the 18R-C and go staright for an 18R-G (EU if possible). but it don't mean you cant get a bit of go out of the old 18R-C
i had extractors, 2 1/4" exhaust, ported head, 44mm inlet valves (were 42mm), and twin delortto dlha carbies. went like stink for an agricultual "boat anchor".
a cheap upgrade from the std 18R-C is to replace the OEM carbie with a weber dgv carbie (need an adapter plate which is about $40) <plug>i have this plate and carby you can buy if you want lol, and the ra28 is for sale</plug>
cheers
ps. aftermarket front & rear swaybars will get rid of almost all your bodyroll
