What is the most cc's possible in a 4 clynder? and any help would be great.

If we're talking VW 4 cylinder then the figures I have are:

90mm stroke x 101.6mm P&C = 2919cc

I think ya might need one of them aluminium cases for it though!

good good thanks for the specs

Pauter sell 3.5 litre big blocks for the VolksWagen Drag Racing championship.
BIIIIIIIIIIIIIIIG bucks tho! But they're getting 750HP+ out of them on alcohol with NOS and turbo.

hehehehe a rusty bug with that in the bak cruising chapel st. picking battles and cooking some rice !
:bounce

hahaha, I think it would be leaving LITTLE TINY GRAINS of left over rice
But thats a mad idea. A ratty old split window. Tubbed, with a full RLR style pro turbo chassis underneath. SCHWEEEEET!!!!!
DAMMIT Skewy, you're giving me ideas now :P

Of course you realise the more CCs you try to get the MORE expense you have to lay out for the pleasure.

Theres an old saying

" Theres no substutitute for Cubes n bumps."

To be on the safe side i wouldnt be going over 2100 with a stock type 1 case, and expecing realibility.

Im not going witah a beetle case, this is for my golf atm im also considering a rotary, but appaerntly there expensive

Rotary's are as cheap as chips!!!:jesus

have not explored the alternate field i know theres heaps of power out there ,,,, BUT... nuthing like a VW stamp

rotarys are readily available get an old mazda cappella or rx3 rotary or something the only problemo is getting someone who can work on them...

New ones need very little work, im deciding what to do, hmm thinking thinking thinking hard.

Definately, Dave, definately. :thumb

Keep it in the breed I say, plus it's more satisfying having a quick VW and opening to decklid to astound people that it is actually powered by an aircooled flat 4 still.

once your cc's go up then u gotta have extra oil cooling, better clutch, brakes coming into view - will they stop u, pterol pump, balancing fan, gearbox updating like welding and recoing

it all ads up very quick !
:cry

the biggest you can go on a stock VW case, is 90x94, wich is 2500cc's although not many people use this set up, maybe because is a $1300 USD crank

Im willing to spend the money on it:thumb

Well if you want the most cc's we used to have an old crane at an engineering shop I used to work at and it was a thumping 12L 4 cyl........all 600revs of it....so big cubes isnt always the way to go....

I have a big engine being built 2.6L Scat/Autocraft components. Planning a T04 with Autronic. .....all sounds good but the scary bit is the price more than 20K and not finished yet. think twice before you start... i am to deep to stop now.
