[R32-GTR-89]

Hey,

i have orderd a 1989 R32 GTST that seems to be clean.... from what ive heard from the person im importing it with...

now.. its automatic and has a standard engine etc etc...

I want to convert it to RB25 and also slap a manual ...

will there be any point of putting a RB25.. can i get the Pro's and conz of each engine ,also what else on the car will need to be changed for it to be manual..

Cheers..

Ask the blokes that have done the conversion.... From what I've heard they love the extra torque in a car thats a little lighter then the r33.

Oh god, not one of these threads again. This has been covered before many times.

Both engines are good, easy to get power out of. Decision depends mostly on what you expect to get out of your skyline. Personally ill stick with the 20 simply because im only hunting about 250rwhp. You on the otherhand might have bigger, bolder plans?

if you got the cash and really wanna do it go for it, remeber you can sell the old engine,box, and ecu off.

main difference in engines is smaller bore/stroke, heads don't flow quite as much, turbo doesn't flow quite as much (im just plucking these from my head).

will make drivability better with more low down torque etc

yes , i would like 200rwkw.. basically 12 second passes... on street tyres.

I could sell my stuff and how much "about" would it cost for a RB25 +box etc ?
