To 30/26 Or Keep The 26?

[zebra]

In for RB10

[Lithium]

I am thinking about making destroker kits for RB20/25/26.......just testing the waters.

Who is in for the first group buy?

Only if you can do short rod versions.

[wolverine]

If there is enough interest I think we can give the Fiat Uno a run for its money.

My mates 120y engine bay. Who needs an engine at all.

Stroke this.

[Mick_o]

If you can get a 1.6L kit for the evo I'M IN!

I like where you are going there Mick, serious potential for you there - you could use RB26 pistons and short rods (so it will sound awesome) to make a 1.7litre... put a T66 on it with a 2" exhaust and get 50psi by 3000rpm. Will be tough!

[Mick_o]

BAAAAAAHAHAHAHA! Just wondering if the T66 might surge making 50psi @ 3000? Maybe I should put a bigger exhaust on to increase lag say something silly like a 3.5" system and bring the turbo on around 1000rpm later?

Lol as long as your car "sounds fast" the chequered flags yours!

I am never going to race so i give no farks about about chequered flags. Re some good tunes every time I drive the car...well I would take this sound any day I drove my car...who cares if its slow

Ask Gerg_31 (I think that's his name) I would bet that whilst his non turbo'd, open throttle bodied RB26 engines he was playing with would have made only average power, they would sound much like the amazing Hakosuka with the right exhaust. Turbo's are an unfortunate muffler of raw engine sound. They take the individual pulsations out to a large degree.

There is some merit to the "sounds better goes better" ideology. I put an exhaust on my VL when I was 19, probably made zero more power but f#$k I felt fast! I'll trade in my noise for power anyday however. Show with no go only tingles in your balls for so long....

Now thats what i am talking about. what a sound, sheer perfection

This is why I love my slow alfa so much.

One of the best sounding cars I have ever heard is Colin Bonds old race Alfa GTV

[Dale FZ1]

You need to experience a BDA Escort, or one of these: https://www.youtube.com/watch?v=qwBxMRG399Q Not quite a garden variety Gemini though...

[Tyranus]

IMO, theres no point in going 28 or 30 unless you plan to run huge power.

[Piggaz]

What's huge power?

[Tyranus]

500-1000awkw

[Ben C34]

500-1000awkw

that's also a huge range! It really comes down to what engine characteristics you are chasing. for a street car more torque pretty much always makes a quicker nicer to drive car. I know I rather a 300kw rb2530 than rb25 due to the far improved driveability. ( and that's why I went for a 30 bottom end) Edited October 26, 2013 by superben

[Tyranus]

What i was trying to say is that id rather keep the 26 and spend the cash on other areas of the car. Id be quiet happy with 300-400kw on a 26. Then again some might not comes down to personal choice i guess. I wouldnt change the 26 if i was going with twins or a average to decent sized single.

[XGTRX]

You don't need power or bottom end torque to have a fantastic car. If you haven't got the cubes rev the dam things.

Roy and dale, get some tissues ready.

I'm with superben. Displacement adds drivability.

Having said that I have sacrificed some low end torque with my new setup for the sake of having a nice sound to listen to, and gone for some big cams and a massively high flowing exhaust.

I think many of you focus too much on which rod ratio is better and are afraid to go much shorter than stock. In small piston engines like the RB's it doesn't really make a lot of difference with reliability/longevity of the motor. Its not as though the engine is throwing around 4" bore pistons. The SR23 engines with 137/91 = 1.5, with a 89mm more is a good example.

There are advantages for the short rod ratio engine in a street car too. The main one that comes to mind is that a radically ported head will work well at lower engine speeds, due to increased piston speeds and higher vacuum pull. This is part of the reason Piggaz's combination works so well.

Better go back to a 2.6 then Paul lol
