right now, i have a fully rebuilt na rx7, 1987 gxl. i have msd, which i fully recommend for everybody, big difference. also getting next a 2.5 inch exhaust and header. new vacuum hoses. msd wires, plugs, oil, filter. full tune up except tranny and rear end.

a couple of questions.

what should i use for my transmission oil. year round. when should i change it. same with rear end.

 

u should search.....but if u cant...redline mt90 or pennzoil snycomesh 75/90..change it ever 2-3 years

 

i use redline MT90 and that stufff works the BEST for my tranny, and i would put shockproof? i think thats what its called, from redline, check out redlines products, they have alot of good **** for imports
