Awesome build man.

Great topic. I want to eventually go this way as well. I've got 2 questions for anyone who can help. Sorry if they seem a bit dumb.

Firstly, if you have the Apexi FC + controller for an RB20, is it going to be entirely useless with the new stroked engine?

Secondly, why do folks guess that Lewis Engines goes with a 2.25 stroker? I mean, for the same effort and similar money in parts (???) I can't work out why they wouldn't go with a 2.4. Any ideas appreciated. Thanks.

Hi,

To answer your questions:

1) It will work just fine, you will need a retune because of the increase in size and Cam's etc

2) Not really sure why they wouldn't go all the way to 2438cc's If they are changing the Rods, slugs and crank it's something you would have to ask them.

Cheers

id say no got to 2.4 because they offer a kick ass rb25 rebuild package that would cost basically the same

rb22 has different characteristics to it than rb24/25 - longer stroke than the rb20 but shorter than 24/25 and higher revving etc etc etc

call Darren he wont be shy of telling you all about it .. he just did my rb22 with few adjustments here and there from his usual package and im more than pleased with the result for my needs

btw - been following this awesome job on rb24 and commitment to doing something a little different ..well done

The reason it says it is for an rb20 is because it is for the rb20 loom and sensors, it doesn't matter if you have a 5L 6cyl engine in there, it will be be able to tune it providing all the sensors and connections are the same.

Thanks for the answers re. this and the RB2.2. Appreciate it guys.

Thought I might post a couple of happy snaps of the car that I just recovered of a damaged hard disk.

Just Fired her up again, The HKS Tripple plate clutch at 600rpm sounds like a bucket of bolts floating around the bottom end....

lol.... Give me $15,000 for the engine and I will throw in the car for free

how about i give you a half finished half circuit, half drag r33 gtst lol

Nooooooooooooo Deal

Anyway seeing that the last video audio was pretty crappy, I took this one not long ago for everyone. Still sounds like a rb20 I think

Anyone know why so much oil smoke would be coming out the breather and form the back of the engine :S has me a little concerned.

is it bedded in yet??

sounds sick!! i love it

[murrayis]

is it bedded in yet??

Nah I wouldn't of thought so it's only done 30 mins on the dyno getting the base run in tune done on the old ECU

I was hoping it was just blow by until the rings bed in.

Hi,

No we didn't have these issues, I guess they will only be fouling the squirers by a couple of mm, you could get some spacers machined up to space the squirters out a little more? Another way around is to notch the pistons to give sufficiant clearance to them.

What pistons are you using?

Im using the 4AGZE pistons

Everything was going ok until this i dont think i have enough room to space them down as im using the rb25 crank and rods not the 26 crank and rods

Im a bit gutted

any ideas ???

[murrayis]

Hey,

Simple, Get a notch machined in the pistons to give clearance to the squirters. You will find they don't clear because the piston pin height is different and the 4agze pistons sit 2mm shy of the deck.

How did you get around this?

Im thinking of getting this notch machined but seems ill have to take out about a 15mm notch height wise

Do you not think this will weakin the piston though.

Im thinkin ill have to go down this route iv come so far want to complete it then i can show the full build

I hear alot about the 4agze piston fitments but know where can i find someone that has done the build just alot of hearsay
