B21 pistons in a B20

Has anybody had experiance of fitting B21 pistons into a late 8 bolt B20? I was wondering about where to get a head gasket to suit the increase in bore diameter. Also where to buy a set of original quality Mahle pistons.

For all problems relating to head gaskets:- Pookie

My B20 is the later 8 bolt flywheel type so should have the 24mm little ends. Was the 240GLT n0ot a turbo'd B21?

I'm not a 240 man but I think the UK GLT has the T standing for "Touring". Engine is B23E and the suspension wheels were upgraded in sporty fashion. A bit of Googling indicates that the 240 Turbo was a 2.1 so there should be some strong pistons around. Did we get 240 Turbos in the UK? LHD only? Turbos and steering gear might get in each others way.

Late model B20 

Just bought a late model B20 from a 1973ES. Has the 8 bolt crank. Big plansds for the engine and start with the B21 pistons. Did you finsd a source for these and other bits such as the head gasket. Any help or advice with the engine build greatly recieved! Russ

All UK market 240s were non-turbo. (Although there was dealer-fit carb+turbo kit available in the early days). You might get OE 2.1 turbo pistons from overseas. Try turbobricks? John

Mark and Russ, I got my head gasket for B21 pistons for my B20 head from KG Trimning in Sweden. I also got my pistons from them. Due to buying quite a bit postage was free. Worth giving KG a call as very helpful people. I also think you are correct that the 8 bolt has the 24mm little ends but KG will know for sure.

John/Mitch Thanls for the advice; will give KG a call. Never used turbobricks will have a look at the site Russ

i've got a set ov 240 2.1 turbo pistons brand new if you won't them at a good pice
