Just go HSR Mikunis they work very nicely, very good throttle response.

 

 

3x 48mm?

or 6x 40mm if you've got a 12 port?

 

 

From a previous post:

 

But yeah, for a maximum effort engine I'd go for the HSRs over anything else - including injection.

 

Edit: If we're gonna get into this we should follow Ned's suggestion and start a new thread.

Anyway, getting back to stroker cranks, I met a bloke some time ago who used the SM article on the 186-235. Local shop did the work. I went for a ride just after the zorst had been fitted, I helped the guy adjust the timing so it went better... checking the 0-100 with his watch!

Some time later I saw the remains of that engine, gave the new owner a hand to pull it to bits, although it was in enough bits as it was. No 1 cylinder had almost dissapeared... never seen such a big hole!, cam in 3 pieces, 3 rods bent like a real bent thing, bits of pistons in the sump. 

Apparently 'made a noise slowing from 220' with a 3 on the tree and 3.08 diff... then went BANG rattle rattle rattle.
