Engine life for 2 different set ups
Basically I want to know which set up will last longest. I am hoping to start re-building in January and want to get at least 100,00 miles from the engine. I live in Ireland and we have 95 Octane as Reg pump gas and also have 97 Octane premium for a few cent more per litre. My car is a JDM 94 SiR Integra (USA GSR)
Option 1
CTR Pistons 0.025 oversize, Skunk 2 IM,Skunk 2 Valvetrain with stage 2 cams,DC header,ACT clutch, Y80 transmission.
Option 2
ITR Pistons 0.025 oversize, Skunk 2 IM,Skunk 2 Valvetrain with Stage 1 cams,DC Header,ACT,Y80 transmission.
The above set up will be tuned with Hondata
I will be machining and honing the block myself(Im a machinist for Pratt and Whittney, a USA company who repair/overhaul jet engines).
I wish to ship the head to Endyn for a 3 angle valve job and full P&P.
There are no reputable porters here in Ireland and since I will be purchasing my Skunk 2 components in USA I want to ship them all to Endyn and have them assemble the head for me.
I would rather go with option 2 above, I feel with the availability of 97 octane here at reasonable prices that I would be able to have a bigger window to tune this motor with consideration to detonation. However if there was a dramatic difference in engine life that would make me consider option 1 a bit more.
One more thing what would the difference in HP and torque between these motors be? I do know they would have totally different power bands between each one.Any opinion on preferences are also welcome.
Go raibh maith agat.(thank you)
P.S. I will be looking to purchase all the Skunk 2 componenets in January so any reliable source to purchase these items who could then also ship then ship the lot to Endyn would be most grateful.

Re: Engine life for 2 different set ups (Willie VTEC)
Using CTR pistons in a b18 bloc will giove you more CR and when coupled with Skunk2 Stage 2's you're gonna make more power with your No.1 option.
As for longevity, in that state of tune there's no reason why you can't see 100,000+ miles out of it, as it's basically a ITR motor with bigger cams.
Why don't you get the work done by any of teh companies in England such as RRR in Lincoln, or I'd highly reccomend B-factory in London http://www.b-factory.co.uk

Re: Engine life for 2 different set ups (crxste)
So between options 1 and 2, the only difference is CTR vs ITR pistons? In that case, as stated above, your going to have a higher CR with the CTR pistons, giving your more hp but adding more stress on the motor. Even with the added stress, either of those options should hit 100,000.
