Well, im just curious what actually changed on the below motors to get that figure?? 165i, 185i, 195i, 215i etc... Was it in the block, heads, intake manifold, exhaust, ems, etc?? Its just that I want to work out what my motor would be close to! Its got a VS Manta Head on a VT Block, running Haltech. Thanks!

165 and 185 are 5 Litres, with mainly tuning differences. 215 are actually 5.7 Litres. and I 195 is 5 litre with tuning and sequential injection. Thats about all I know.

Yeah as 87vlt said its mainly tuning but they increased compression in some models did things to the heads to give that bit more peformance. little exaust tricks and what not but remember all those figures are flywheel Kw not rearwheel kw

215 is a stroker.Hey man just wondering y u put the exact same question on the street commodores forum?

He want's different people's input on the matter im guessing

Thats it INFLYT! Some people give better responses here and there! Just like people advertise their stuff for sale on more than just ONE forum! so more ppl see! Also just for the fact that probably More Holden V8 people would be on that forum, than on a calais turbo forum... But yeah, just good to get different opinions... Some original photos have not been recovered yet.
