Boring out a 2.0 ts

Hi all
My 2.0 ts engine is soon to be in bits and I was planning to re-sleeve the block, replace the rings and maybe the pistons. The thought has occurred to me that since Iím going a long part of the way, I may as well go all the way.
How big can I take a 2.0l TS block? Could I get it out to be like a 2.2l?

I don't think the 2.0 can be bored much I am afraid.

The cylinders are pretty close together, and the water jackets are also very close, which doesn't allow much metal to be removed.



I am sure someone will be able to confirm this though

Biggest std overbore is 0.4mm, which won't get you anywhere near a 2.2

As Symon says, tolerances are close already, it would take major work to get to 2.2

I think the bore spacing is 90mm between cylinder axes so with standard 83mm bore you get just 7mm thick wall between cylinders.

AH Motorsport can suply you 84mm pistons so you should be able to get from 1970 ccm to 2016 ccm. Maybe you could go to even to 85mm to get something slightly close to 2,1 engine but not much further.

For 2,2 engine with 91mm stroke TS engine has you would need something like 88mm bore and thats not posible

I am not sure if I remember correctly, but AO user marko has a 2,1 TS with something like 200PS...

I'm talking to Pro-alfa.com (Alfa Romeo tuning) at the moment, they advertise a 2.2 conversion - 2.1 something
Jon says....
I have plenty of blocks in stock from which to do a rebore for these suitable pistons. The cost of an overbore to 86mm would be £150.

I have a turbo so wanted low compression pistons, this was Jon's reply...

I would be using Capricorn or CP pistons. I have some designs on hand but a reduced compression ratio of 8.5:1 or 9:1 would probably do the best job. The material would be 4032 as in the Wossner which has a lower coefficient of expansion than traditional forged material 2617. I can work on a quotation for you for these pistons. I'm estimating around £750 for a one off set with rings and pins and approx 4-6 weeks delivery.

Wossner sell pistons in the following bore....

Bore sizes available 83mm / 83.5mm / 84mm
Engine CC 1969.46ccm / 1993.26cc / 2017.20cc
Stroke 91
