Many said,mainly US guys car with 2.0L crank rev faster than with 2.5L,not sure why,but people prefer there to run 2.0L cranks
You can check few threads over Nasioc where is thread about the longer rods vs normal size rods
As above for de-stroker you will need to run +2mm Longer rods,EJ207 cranks and off course pistons

Yeah pinning is the way to go for the 2.5 for added strength.The expense of going 2.35 is "everything" from the CDB block which are getting quite rare to find now where as the 2.5 can be found much easier and cheaper,plus all the machine work that's needed on the.2.35 rear thrust conversion 14mm head studs etc etc....,if you are building a 2.35 your building for BIG horse power,strength and reliability and to do it properly "COST"not to say a 2.1 doesn't,but the 2.35 cost much more.Before I was going to start my project me and Neil spoke hours about which direction I should take wether I do a 2.1 stroker or a built 2.0 or a 2.35 the 2.5 was never mentioned.SJ.

EJ25 crank goes in both, what bore piston's are used in a 2.35?.
Machine work for rear thrust conversion was about £150 iirc for my CDB, is it a different process for EJ22's?.
I'm not knocking it, I'm genuinely interested.

What is most expensive on 2.35L?
Do you want build 2.35L with cheap parts like Eagle rods or Manley H-Beam rods,I wouldn't
If you are going with 2.35L do you will be running better cams/valves and springs,retainers,I would
Would you consider to run on 2.35L 11mm headstuds,I wouldn't and due this almost everyone using 14mm headstuds,which not cheap plus machining for heads and block add cost
Rods are used standard length,pistons are specific for 2.35,crank is used EJ25
Plus block is not very common over here and usually you can get them cheaper from US

I've seen EJ22 blocks on here for around a grand. I understand EJ25 block's go for far less but once you factor in pinning then surely it's not that different?

In de-strokered 2.35L crank is EJ207,for stroker from EJ22T 2.35 crank is used EJ257
Machine work is quite similar on both,just EJ25 don't needs to be converted to rear thrust

I get that, but from what I'm reading that's down to cost. Making a 2.3 without using the £1k EJ22 block. The part I'm struggling with, is whether there's much difference in cost of the EJ22 block, and pinning/inserting a 2.5 block. There's not massive differences in price of crank's, and it must be simpler to buy standard rods than +2mm. Unless the piston bores are rare on the EJ22?.

About the price on the CDB insert and other bits,this should answer someone else as I don't know prices for this
+2mm longer rods are available and many companies selling them and they're not so difficult to get

Doesn't take much.
An EJ22 is usually around 12-1400 quid.
Probably get bare 2.5L block halves for around £200 or so. You'd still use the same quality internals as if you were building with an EJ22, just the block will be cheaper, even when you've added the CDB inserts.
There's no really cheap way of doing a 2.35, as you still need the turbo etc to justify it.

Taken from another thread
I was very surprised tbh was expecting more than that for sure Alyn is a very helpful man fair play to him, took time out to have a chat from his busy schedule, credit where it's due
dont normally bandy costs around as people dont always compare "like for like" but here goes we have recently managed to review the pricing for the inserts due to quantity done and making the process more effecient, etc. so they are now £450inc. fully machined and converted to CDB - please note our conversions are extensively machined to ensure the integrity of the insert we also do our own 14mm studs kits which are very cost effective and include correct dowels at £345inc./full set 4cyl blocks (EG33 versions to special order)
