battle of the rb's

[NismoSilvia270R]

between the rb20 and rb25, which do you prefer?
consider...
size...revs...aftermarket...ease of install and maintainence...
block and internals' strength...

rb25 hands down. the 20 isnt an option i would even consider.

[NismoSilvia270R]

nice. kckinneys looking real good about now too. full conversion kits to make it fit right

0 offset on 8" wheel is four inches in? and +30 is 3cm toward outside?

rb25det or rb26dett!! get the mckinney motormounts kit, wiring service, and custom driveshaft. they even sell custom downpipes to retain the stock twin setup.
