Rb20 Or Rb30?

[ItsBoostin]

Just looking for some advice on which direction to head in.

If i want it i could have a RB30 bottom end with turbo pistons for pretty much nothing, every one ive spoken too keeps telling me to do the RB30 swap and have X amount of power and be happy as larry.

OR

Keep the RB20 and go for my goal of 200kw with supporting mods with the likes of a high-flowed r33 or r34 turbo.

Car is a 93 GTST with 3inc turbo back exhuast FMIC spiltfire coilpacks.

Want to use the car as a good street car that can handle its self at the track and teach me how to drive.

any advice would be appreciated.

In isolation its an easy choice...but how much money do you have to spend and how much cn you and your mates fo properly yourself?

+1 RB20...and take the RB30 for later

I agree...

That way you can take your time doing the Rb30 Properly...

Money is no real issue i would rather wait and have the money to do things right either it be RB20 or 30 rather then just diving in.

Most the work could be done ourselves mate owns his own workshop and knows his way around performance engines.

If money is no issue....mod the RB20 to your 200kw. Drive it around until the RB2630 is built up and then bang that in there

+1. Take your time and do the 30 properly. With money being no object, there's a lot that you can pour into it that will squeeze the scrote once fitted, as you'll soon get used to the power of the 20 and want more.

Thus is the trap with performance cars - The money pit factor.

RB20 was always the way i wanted to go plus there was always the legal poo.

just seemed every one had no faith in the RB20 and the 30 was the best thing in the world

rb20 with a gt30 and supporting mods, imo its alot more fun to drive than a car with low down power and will be good on fuel if u decide to take it easy

[CEF11E]

I have had both in a 32 and can give you some info from both sides.

RB20 - really easy yo get 200rwkw out of. exhaust, turbo, intercooler, boost controller and fuel pump and ecu remap. thats all you need. if you go with a good turbo like a 2530 power delivery will be excellent, it will rev like buggary and it will last. it will bore you after a while and you will be on an endless chase for more power.

having said this is is an excellent powertrain for a rwd 32. and driven properly will be a VERY fast street car.

RB30 - now you will have to replace a lot of things you didnt with the rb20.

gearbox, clutch, engine mounts, injectors, afm, ecu, fuel pump, turbo, exhaust, intercooler, boost controller plus the build itself. the car will have more torque than you will ever need, stupid amounts of torque. if you are doing 80 in 5th and mash the throttle it will pull like an RB20 in 3rd. it makes effortless power, sounds cool, is SHITLOADS OF FUN TO DRIVE but probably will not be faster than the 20det powered 32 unless you are a very skilled driver. an most of the time you are trying to get the power down.

it will cost 4 times what a 20det would and you will have a ball in it, but the is NOTHING wrong with the good ole 20det

Everything CEFFIE says is true.

Personally, putting a 3L in my 32gtst was the best thing I ever did. Yes, there were pitfalls and yes, it did cost more than I originally planned (but that could be said for most things performance oriented).

I love it and would never think of going back to a 2L!

Well I think I may be able to shed some light...

CEF11E tuned my car and we made just a shade under 200rwkw at just under 1 Bar on my 20DET.

I've been in his RB30 and it pumps, however, as he said its really only as good as the driver and you will need to do the other stuff to support the 30.

My 20 is my daily and will hold its own with pretty much anything apart from the exotics, despite what some might say it is also quite responsive. So for the time being I reackon learn the 20, take it to the track and enjoy it - I guarantee it will not dissapoint and then when your ready to upgrade do the 30
