im not a 100% but im sure the the piston webs have changed shape. The edges that are closest to where the conrod would be are now flared upwards and are also look like they have cracks in them.

Ok so it looks like a 2.35 build again but im going to need a few bits.
The pistons have grabbed the pins and spun them in the little end of the rods so i need a full set of rods. The piston with the worst of the damage ( number 3 ) seems to have taken out the big end as well so i need a crank because i will not grind a 500bhp+ crank. The pistons as they have grabbed the pins have also tried to twist in the bores and the bores are scuffed and i will now need to go 1mm over to 98mm pistons.
So what parts are recommended for the job
Crank?
Pistons?
Rods?
Oil pump stock/11/12mm ?
Head gaskets?
Bearings ACL glide / race?
All opinions appreciated.

Hi there
Depends on more factors(budget) and mainly power what you are looking to run
Crank should be enough standard EJ257
Pistons again depends on budget,Mahle Power pack are good and many people run them in high bhp
Rods again depends on budget and power what you are looking to run,but usually K1 rods,Carrillo rods etc.
Oil pump depends on cams are used and other questions,if you are looking to run aftermarket cams I would go down the route of the OE 11mm
HG Cosworth without the doubts
Bearings again ACL Race bearings

Thanks for the reply. power wise i would like 600bhp and for it to stay in one piece. Budget will be what ever it takes ( within reason ) to build a reliable bottom end that that will do 600bhp and have some head room. Would be nice not to be limited by a budget and we could all have titanium crankshafts MMC conrods and beryllium pistons all in a one off closed billet alloy block with a dry sump.

Hi there
I would say yes would be OK,not sure if its possible to buy nitrated crank,few months has been problem to buy

I was using a HKS steel 79mm crank that was left over from my old 2.1 set up. I would love to use another steel crank K1, HKS, Cosworth etc but they are over twice the price of the standard crank.

People running stock crank at high 700bhp without the issue,we will be running too stock crank
Arrow billet crank are probably best cranks from reading posts on the Nasioc or 22b

Ive built a few engines using the 83mm crank, including a 2.0 (2.25) it worked very well. Ive also got a 2.6 (83mm stroked 2.5) waiting to go in my JDM Bug STI, it should make a great road car when I can finally get time to do it!
Rod ratios, hmmmmmm, a very interesting one and I think alot of info is based on opinion rather than science/fact. My thoughts are that using an 83mm crank with short rods (128.5mm) gives a ratio of around 1.5 which is generally classed as the low side of std ratio, under 1.5 is said to be short. However there are alot of big V8 engines running 9k rpm and over that happily run well under 1.5 ratio.
The engines I have built and dyno'd/driven have worked very well. I will put a project thread up once I get the 2.6 sorted

Didn't you use 130.5mm rods?
Everyone talks about stroking ie 2.0 to 2.1 / 2.2 to 2.35 and 2.5 to 2.6 or 2.7. What exactly is wrong with the ej22t on its own would it not be the middle ground between the 2.1 and the 2.35 ? Obviously forged I mean ?! Pls excuse my lack of knowledge.
