Forge piston help

[<GB>]

my car has the crosworth pistons and they are not noisy at all, i cant even hear any piston slap on cold start, i think they are teflon coated, i remember hearing justins car and his was really loud with the hpfail build so id be carful what ya get

But even if it was his fault I can't really prove it, and I never signed anything so I don't really have a choice but to fork out for the rebuild

It's not necessarily about going after someone for reimbursement...you'd still want to at least know why it happened so if you knew it was to do with the tuning you can do things differently next time around, if you knew it was something else you can change whatever the weak link was etc.

If you’re planning to keep the car go with forged internals.

You might want to also get the engine inspected to understand why the big end failed……. May be tuned, oil, fuel related etc…..

Would be wise you get the heads serviced and stronger heads studs and an aftermarket head gasket, belts, pulleys water pump etc….. it has to all come off either way.

Hmmm....sounds familar.....

15w 40 and how good it is..[/quote]

That might be good for shutting up a built engine, but I wouldn't use it in an unopened one.[/quote]

What do you mean ? Not using it in a stock gt ?[/quote]

Correct.[/quote]

Why?

[dr20t]

Newbie perhaps ask the oil question in the other delvac thread you (or kiahatsu) have.

To the original question - if your setup is stock and you envisage will remain that way forever, then I wouldn't worry about forged pistons.

However for the money it's extra insurance. Forge pistons are less susceptible to failure from detonation (read less not completely immune)

As said by others I would find root cause of your failure before committing to rebuild

Ej255's had a bit of a history with bearing failures prematurely.

Just one correction I'd like to make to someone (can't remember who) post earlier - you dont need block work to fit forgies. They come in standard bore size too.

If chasing more than 220awkw I would sleeve the block for longevity

Brandon? Once and for all? ......

You seem to keep typing crosworth? for some unknown reason?..on here....on your profile...everywhere!

I am going to try to get to the root cause, like I said I am taking it back to him and at the end of the day I want a reliable car but still be able to maintain the current power of 180kw atws

Maybe that's having my cake n eating it... Is there anything I can do while the engine is split to make it more reliable with that power??

[jslayz]

Sleeve it, big head studs, quality head gasket.

For reliability i guess you will already be going good quality bearings anyways too.

Good luck,

Stock engine should outlast the rest of the car at that power level.

Needs to be tuned correctly and have the right supporting mods

i do not have a stock car, bigger intercooler, 3" TBE and a tune I think but still relatively stock

However for the money it's extra insurance. Forge pistons are less susceptible to failure from detonation (read less not completely immune)

I have asked Michael bout the loudness of forgies and he said although not loud you can still hear them, so I would love a clip of people forgies even if they where extremes







Sorry I didn't mean to put that in a pm I meant to press quote..

you probably wont hear it very well in a video clip, i would be wasting yours and my time recording mine as there is no noise

[dja]

The money your being quoted is up there.
If your honestly going to spend 5k, i would buy a brand new ej255: 2300-2500 and some quality forged pistons, 7-800 for cosworths/CP etc etc
And some headstuds.
Have it all thrown together, and you have a forged bottom end, and you will never break it at 180kw atw, as long as the tune is in check, and you have headroom to add more power.

This will all be under 5k.

Stock rebuild with labour is around the 5k mark with new gaskets, water pulp, head servicing and timing kit

For another 700 in pistons and a couple of hundred to assemble I would definitely do it

Also have the main and rod bearing clearances checked and throw some acl bearings in there at the same time for safety sake
