Plannin to rebuild my 1.6 b/end usin 0.5 oversize pistons (standard compression) with a kent cvh34 up top and hybrid blower. Just wonderin what sort of power to expect to get out of it realistically?? I'd like over 200bhp, would i need low comp pistons to get this?? Anyone got this sort of setup?? Cheers in advance!

 

What intercooler you got

 

pace mate, half width one like.

What other mods have you made to the engine.

 

chipped, k&n, scorpion system at the mo and made 168bhp at 16psi but bottom end is tired and needs a rebuild! Spent a load of cash gettin the car up to scratch so far, so ain't done much to the engine. Was also gonna get a 5th injector.

I recon it wouldnt be far off 200bhp @ the flywheel, get a better intercooler and bin the k+n if its a cone and you will see an improvment.

 

Tis a cone, what filter would u recommend?? Standard airbox? Cheers for the response mate

 

Deffo a std airbox, thats what im using along with the std ford panel filter.

 

That's interestin to know, heard a few peeps who have said that! Have to get hold of one, car came with the k&n!

 

you will only need low comp pistons if you are planning to run big boost 20 psi +, if not dont waste your money on them and buy some good quaility standard compression ones.

To have a 'safe' 200 + bhp i would use low comp pistons with the correct fuelling.

 

Is it a good/bad idea to machine standard comp pistons to lower the compression, only i was gonna buy a recon bottom end that came with some new standard comp o.sized pistons. Really want it to be reliable as i was plannin on doin some track days when it's done.

 

well i wouldnt machine pistons, i was advised not to go that way by the engineer who built my bottom end last month, if u want anything reliable do it properly while you have the engine out and buy low comp forged pistons,

But then people say its fine to skim pistons a bit, but i didnt want that.

up to you mate, think about it and save up the money to build a good bottom end with a good setup it should be ok.

 

Cheers for the advice mate.....like u say better to do it properly!
