Best forged pistons and rods combination?

[billybob]

yes thats about it but it depends on your setup if you use wiseco dished pistons to bring the compression back to standerd you have to use .6 trd headgasket

if u wanna run bigger boost though u want a lower c/r that way the motor will take more boost b4 it "pops" my 1.2 mm gasket didnt change it as much as i thought it would.... and i have dished pistons aswell and i find it very drivable

 

[Sheldon]

well but then you can run much higher boost! depands all what you want it for bud

 

[wee-jo]

To say I'm now confused is an understatement

 

[billybob]

the bigger the headgasket the more boost the engine can take.when you lower your compression ~(bigger head gasket)you can then run more boost

So ideally if I want more boost I go for a thicker headgasket but can expect to get more lag?

Thicker headgaskets lower the compression, and make it safer to run higher boost, but lower the responsiveness of the engine when off boost I doubt the change to lag would be very noticable at all.

Depends on what kind of turbo you're looking to run really, if you're talking 1.4-1.6+bar on a TD04 or something, then you'll want a thicker headgasket, but if you're only talking 1-1.4 bar on a Hybrid or similar, you'll not really need the thicker headgasket. For example, Toby on ToyTuning uses a TRD headgasket, which is around 0.6mm on his hybrid turbo built engines to retain off boost performance and to get a higher power figure when on boost than you would with, say, a 1.2-1.6mm headgasket (due to the higher compression achieved)

but toby ran wiesco low comp pistons in those builds that kevin did.

that works out at virtually stock compression.

0.6mm trd headgasket with 10cc dish rather than flat tops and a 1.2mm hg.

if you really want to lower it couple up low comp pistons and a 1.2+ hg.

and the 0.6mm hg and 10cc dished pistons have taken 1.4bar td04 in the past and im sure could take more.

[Dave.]

You're right about the pistons, I should have been clear about that

I just meant that in general, for big high boost turbos, the tendancy is a thick h/g (to lower compression further), and for small (relatively) low boost turbos, many people feel the thicker h/g's aren't as necessary. I hope that's not wrong lol...

What about wiseco flat top pistons and a trd 0,6 headgasket?
Can it work if you tune it with an power fc (apexi) and a garett 2560R turbo?

 

[sx_turbo]

your better off with a 10cc dished piston if you are going to use the trd 0.6mm gasket mate, as this will give the engine roughly stock compression.

if you go flat top and trd 0.6mm gasket, you'll be close to the compression of a n/a engine, and i dont think thats a great idea on that turbo

This will alter your comp over 8,2 (stock). And if you need with this setup to run serius boost you need a racing properties fuel. Put if you plan low boost (near stock)on a 100 ron fuel then power fc can handle well.

you mite get away get a water meth injection kit at that comp ratio, but it would take at least that if not race fuel especailly if you plan on running any boost.

Can add charge cooler/chill water,icebox,fuel coolers and go mad with comp too
But this will take you to an other level of engineering!
