rb24?

[rb20sillouette]

I'm looking at doing a moderate build on my rb20det.

Can anyone give me approximate prices on a few things.

Adjustable cam gears?

Custom Inlet manifold?

High flow of the t3?

Mild porting of the head?

tougher head gasket?

fuel system (any ideas?)

Stock Computer (what can it handle?)

Can you guys advise anything else to do to an rb20 to get a reliable 190-220rwkw?

also,

is an rb24 possible?

and how much would it cst fo rthe rb26 crank and rods?

Ive heard of MASSIVE improvements with this.

cheers

rb 2.4 is an expensive exercise unless you can do the engine work your self for 190 200 rwkw no need for a tougher head gasket. a guy from here made 188 rwkw with a hifowed turbo ecu bigger fuel pump and 18 psi

rb2.3 is a cheaper exercise with the rb 25 crank and rods

the info is at the bottom of that page for the rb2.4

any idea of price?

I'm not that experienced, so i have no idea how much these will cost and if they are rare.

I expect it would be a good $500 for the rods and pistons???

How much for the rb2.3 and what kind of power am i looking at?

I have friends who can help me do the work, we did the engine conversion it is now in, by ourselves. Thats still running fine, so there shouldn't be much problem in fitting it, its just the tuning part i'd leave up to professionals.

How much to high flow the t03?

Ive been told that aftermarket ecu's need continuous tuning and are a waste of time and money and one should just remap and chip the stock computer.

Any advice you can give me?

unless you aiming for more than 250 rwkw the 2.4 is not worth while the stock rb 20 will do the job to build the motor 5k+ hiflow a turbo 1k plus you ned to talk to a turbo place for a ecu chip 350 or so

Meg,

What do you reckon the 2.3 would cost as a comparo.

Is this rods, crank and pistons from an RB25? I'm guessing it would require machining to fit these parts.

Would the engine still be a good reving engine seeing as the RB25 is built for cubes not revs to develop power?

[meggala]

will the rb 2.3 is not a bad motor one company in in japan made over 1000 of them should rev fine with good rod bolts these motors need custom pistons to suit of 81 or 82 mm tomei make the pistons for the 2.4 they are 30000 yen each or $440 each so nearly 2500 for just pistons at least 1 k for the machine work 1k for gasket etc then 1k for assembly you see where its heading then if your going to do all this work you want a big MOF turbo with external gate 3-5k then you need injecotrs afm the the rb20 box wont be strong enough so you need an rb 25 box 2k + with clutch its not worth it unles syou going for an all out track car to take a record with the 2.4 kit I have seen 700 hp + made with t88 turbos.

and the stock rb 20 will handel 250 rwkw so why change

Throw the 4AGZE pistons in instead of the tomei's and it's a bit better deal... the 4AGZE pistons are 82mm and are forged apparently.

But yeah for the cost it's not worth it for a street car...

You could have a good wack at the HPI drag records for under 2.4 class though

[meggala]

oh and I forgot cams add another 1500

[lowlux]

what if u got a blown rb25 motor,then take the crank out,maybe use the rods,get new 4agze pistons, bore the block, that would make the cost alot cheaper wouldnt it,also i could get all that for relatively cheap

[meggala]

thats how you do it

but I'm qutoing if you ahd to pay for the work I heard the gasket set for the rb's are around 1k

frightening

[lowlux]

DAMN!!! 1k for just gaskets what would u do about oil pumps and bottom end things like that?

what would the outcome of a rb23 be? as in would they be up there with the rb25 tourqe wise?
