Rb30's And Rb20's

[cactus]

Hey guys, was looking for a little information i was unable to find.

What do you believe would be the best option, leaving an N/A rb30 motor stock internally but adding a turbo and running low boost (what would be the highest you could actually run?) or simply just buying an rb20 and bolting it straight in and leaving it stock... (the car weighs around 1300kg) just asking because i dont wanna spend too much money, as the car itself has cost me enough as it is, and the motor is only going to be in for about 3 years at which point im going for a 25.

-also do you know if the rb20 5spd is the same length as the standard rb30 5spd box?

(incase you are wondering why i ask all these weird questions, i own an rb powered HQ and looking to upgrade as soon as possible.)

any info would be great cheers.

I say the 30 stays

not sure what the compression is in standrd rb30 form but a low boost example would probably be doable.

or you could read the rb30 thread above... and instead of upgrading to an RB25 in the future, build a twin cam 3L turbo.

I'd just stick with the rb30e+t.. works well for quite a few people with 200rwkw or more achievable given good tuning.
