Default 2.1 and MD321T

Anybody running this combo on a newage? If so good and bad points please, i have a 2.2 block here with forged internals i was going to drop in. Or just do the norm and drop a 2.5 in her?

I need to decide which route to take, full blown 2.2 or a 2.1 stroker. Cost is swaying me to the 2.2 i have but it could always be sold i suppose to fund a stroker or a 2.5.

Ive ruled 2.35 out due to cost mainly and its a road car so will be sticking with current supporting mods just changing the block.

2.1 and 2.3 use the same crank if I remember right so use you block and forged pistons and get stroker rods for it it will be great

Yes they both use a 79mm crank however piston size is different. For a 2.1 a 2.0 block can be used no problem

For a 2.3 you need a 2.2 block or a destroked 2.5block or a relinered block

I have forged internals for a 2.2 block and the block but its 75mm crank, maybe just stick with what i have due to costs.

Hopefully somebody out there will be running a 2.1 or 2.2 with a 321T to get some feedback.

I would go for the 2.2 block its a good increase in cc and it would suit a 321T. should be good spool up too. Just my opinion.

For a pure road car the 2.5 is hard to beat, the torque is immense.

However I love the 2.0, also a 2.1 is a good compromise, at a price I find acceptable.

IMHO
