3L buildown... to 2.5L
Does anybody know what would be involved in making a 3L into a 2.5L, this is based on an S2 block. Is it even possible? I am trying to reclass our GT1 3L turbo into GT3 for PCA club racing.
Either that or would anybody be looking for a 3L turbo?

but for GT3 you can have a 2.7...
But after you multiply by 1.3 for the turbo it will put you over 3.4L (3.51L)... GT1 baby. These cars can be competitive in GT1, especialy with a 3L turbo (3.9L eq) and the right driver... but talk about a fast crowd.
GT3 is up to 3.4L, over 3.4L NA is GT2, over 3.4L turbo is GT1.

I'm looking into building a 2.8L bored out engine this winter...

Hey Kevin, I just noticed...are you getting any "placement advertising" money for showing the nose of Craig L's car in your avitar?

hi Sloth,
i too am doing just this same conversion. it requires a 2.5 crank,sleeves and pistons to achieve the required 2.6 litres of displacement.
i have little doubt as to the effectiveness of a 16 valve 2.6 turbo motor.
as a suggestion... import drag race tuners have lots more experience with multi-valve dual cam engine performance...not to mention vast turbo knowledge. as always,it's critical to find a "read deal" tuner and not some poser. we've determined that 470 hp at the motor is very realistic using the 16 valve head.
good luck!

I am sure that anything could be done. The engine is currently an 8v 3L turbo, it is being rebuilt and I am curious to know if it could be dropped to a 2.5L using the same head and block.
If we decide to just sell the 3L and start anew I will certainly post details here. It is a sweet motor.

That is probably the easiest thing to do. I just wanted to hear the possibilities.
When we figure something out I will have to post information on the 3L should anybody be interested in it.
