Sense, Spend Money On Rb20 Or Rb25?

[XRATED]

I still firmly believe that you can only enjoy an rb20 after you have owned/driven and built more powerful cars. The 'thrashyness' factor is hard to re-create with a 25, 26 or 30...

You just have to enjoy them for what they are and try not to turn them into somthing they can't really be. Stock or small turbo's.. under 240kw but dosn't drop off to hard in the top end. Collar, good oil pump and a decent tune.

Then just enjoy it for what it is!

Cheers

Why an oil pump Justin? , i always thought rb20 was just bolt ons and thrash? .

honestly, all i have done since learning that you can LEGALLY put a RB25det into an R32.... is search for a decent RB25DET!!!!

i never realised this can be done legally!!!

can an R32 GTR brake upgrade be enough for the regency approval in sa?

Hey mike,

Ive got a 20 with a 25 turbo, fmic, pod, 3 inch exh etc

Before you get a boost controller, see what boost you are getting, you may get 10-11 psi.

A boost controller is a waste of cash for an extra 1-2 psi (25 turbo ceramic, 14psi max)

I spent $400 on a sweet boost controller before i got the new boost gauge. oops.

Lots of bits can be used on a 20 and 25 like if you get a good turbo, or fuel pump, you can swap over later.

Just think about what you can use on both motors, and all the other mods to your car, keep the 32.

All that is needed is the same size brakes as the donor engine's car. So R33 brakes to go with RB25. In my case I've put a Neo in, but not putting in R34 brakes. The 296x30 will be good enough to get it through Regency.

GTR brakes will also do, but you don't have to go that fat to be legal.

The main problem with worrying about a legal engine conversion and putting the car over the pits at Regency is all the other things that most people have on their cars that won't pass, like adjustable suspension arms, height adjustable coilovers, boost controllers, fibreglass bonnets, etc etc etc. All that has to come off to be inspected. At least for me I only had to leave off the boost controller and swap the castor arms back. I'm crossing my fingers that they will let the Momo wheel go through, as I don't have a ready alternative available.
