Right here goes, i been told i can change my linners for bigger ones with increasing space to fit and would have to change big end, iv nearly got all bit to convert to injection.
1. would this increase bhp
2. be reliable
3. would i need bigger cam etc
78mm* liners will slot straight in. Probably best to source steel items, for durability/reliability, given the liner wall will be thinner. You'll of course need the 78mm pistons & headgasket (fire-ring wise) as well.
It'll naturally increase CC, and yep, a hotter cam than standard would probably be beneficial, although that also depends on which turbo you'll be running.
* 76.6mm (aka 'grp A'), and 77mm are also available as a direct straight fit.

cheers, what turbo wud you suggest? within cost factors too. i was told 76.6 was best in terms of strain on engine.
The choice is endless. Is it going to be a 'fast road' car, dragstrip beast, track attack motor?
76.6mm would be the more durable, but for the cost vs gain, you'd be better off staying o.e (76mm), or all out with the 78mm spec.

Yea i know wat u mean, bet the piston kit is £££sOriginally Posted by Mart
So if i put the 76.6 in, i was told the pistons wud be ok with standard?? or is it dodgey!!
do you mean standard pistons in 76.6 liners?

Yes mate.
it would rattle like a mofo if you did that, probably smoke too. you match the pistons to the liner, so 76mm piston in 76mm liner 76.6mm in 76.6mm and so on

cheers, any ideas where too get good piston kits and cheap
depends if you want standard or oversize?
Well if im going bigger might aswel go 78's lol!
ouch blimey!!! thats scary. Converting to injection is costing a worthy ouch, need santa too come back!!
