Best brand of forged internals

[Ryan]

What peoples opinions on the best brands of forged pistons and rods?

[Ryan]

And if I'm using a '89 RS block with V3/V4 heads, I should be ordering pistons to suit V3/V4 models right? Just wanna double check on this.

[Guest DMSREX]

I was told for pistons either CP or Mahle and rods either Argo or Pauter ending up not doing it as the boss of all things financal (wife) said no

[Ryan]

In the past I've used Eagle rods but curious as to what others think

[nt_a_foz]

JE, Wiseco, CP any of those are good

Eagle are usually the cheapest rods from what iv seen

[wrx_lou]

Argo conrods are suposed to be one of the best.

If your wanting to spend the money i supose it would be worth looking into rebuild kits by HKS and the like.

[Guest boostcut]

hks are eagle rods i think bro. just with another 2k on top. i know for a fact the hks pistons are now trust pistons which are a crap copy of a wiseco.,

edit: that info is based on rb26 gear not suby..

JE is what PBMS chuck in some of their engines. AFAIK, they aren't the best out there, but aren't bad at all either. Would call em middle ground from what i've heard. And i've heard eagle and scat rods are the same, or atleast scats where the same as some other brand, i think it was eagle...

I'm satisfied with my scat rods and JE pistons, they were affordable, and have done the trick. I give them shit, but that's the road going version of giving it shit. No idea how they'd hold up on the track.

I wouldn't touch anything HKS anymore either, it's just a brand name, that's it. I've been disappointed time after time with them.

Oh, and factory forged stuff can actually some of the best out there, it's just HUGELY expensive new.

go with what your engine builder is comfortable and has experience with.

Mine recommended eagle rods and CP pistons, on factory bearings and some aftermarket headstuds..

My car is certainly making good power and feels strong as.

Oh yeah, bearings, my builders tried out ACL race bearings on a few motors, and were hugely disappointed with the quality, they only use factory bearings.

that's a big call. got anything to back yourself up?

[Guest boostcut]

other than the fact i have had them both sitting next to each other and look exactly the same? no.

ARC make bearings?

I went with CP & Pauter, have had arias fail on me in the past.

[Guest boostcut]

i think he means acl. lol

[Guest]

Yeah PBM do like the subaru bearings

A few of us have been running ACL race for a while now - no probs - touch wood...

[Guest boostcut]

the problem with acl race bearings is that theyre harder than standard bearings and when you run a bearing it farks the crank too

did you take a photo? cant say ive seen an hks rod that looks like an eagle rod before. They look quite different normally, HKS rods have a chunkier little end among other things

[Guest]

When you run a bearing you should chuck the crank anyways - you can never clean the debris from the oilways completely

or so say PBM and others

[Guest boostcut]

yep. i have a photo of it. my racecar has hks rods in it, and theres a spare set in the box of parts and a guy i was talking to had some eagle rods. they were an old style of eagle but never the less.

so if you have a $5k stroker kit you would throw the crank away? what a load of BS. you can clean them out if you know what your doing. pbms just want to make money... i dont replace a hose and use the old fitting... im trying to make money not friends!!!

[Guest]

I would say JUN. Although I believe they have their pistons made by Cosworth technically

They just recommend getting a secondhand one thats in good condition - hardly makes them $$$. So im sure they have there reasons.

Yeah AFAIK JUN kits are cosworth components , bar the cranks i think

That is exactly what Al Maclennan did with mine - biffed it and got a second hand one. And he put in ACLs ...

I reckon if you put 5k worth of crank, rods and pistons in and go racing, then you are willing to lose 5k worth of crank, rods and pistons =P

[ReubenH]

Regarding big ends f**king cranks. This is my GTB's crank. That motor was stock as.
