oh if your asking about torque you got plenty

its twin turbo

redline at 8000 rpm it i might be wrong i think its 10000 till you hit the rev limiter

bhp is 245

torque is 250 lbs.

rotary engine is a wonderful thing (seals are have to be rebuild every 70k miles) but u would not have a problem on overheating. and there is not a lot of moving parts so its free on redlining it can handle it. the power of that little thing beats every engine on power to litter ratio.

about the bmw e30 its absolutely a champ its a 22 year old car but no rust the inside is beat up but can be fixed. the best part is the suspension of that beast. pop a stiff spring on that beast you can cancel out understeer and oversteer (i found a video of an e30 that turns like an F1 racer). but stock its a monster soft on bumps but hadle corners like a champ so its a both of the two. and i dont have a lot of electronics on the bmw no pwr locks no pwr window so i dont need a lot to change all i need is a good a/c and heater radio and thats it.
i think after spending 8gs it would be a good or an amazing car with new paint and an acceptable interior.

pls share your ideas because i dont want to tackle this project and stop on the middle if i cant do it. i want to have all the answers to the problem before i encounter it.

thank you guys for your info

more would be merrier
