Hello guys , after a head gasket failure of my b18c jdm sir i'm going to build a new engine,i will really appreciate if you tell me your opinions or any experience with a simmilar project

This is my setup:

-jdm b18c typer block
-itr crank
-itr rods
-itr 00' spec camshafts
-supertech springs an ti retainers
-pr3 or p72 head(i'm not sure yet)
-ycp ctr pistons
-arp head studs
-acl rod and main bearings
-oem head gasket

 

ditch pct pistons and get a b16 or itr piston. pct are super heavy and the dome in a b18 is counterproductive

 

i hear that are very good pistons with a p72 head but maybey i will have issues with timing, for that i'm not sure what head to use ,i have a pr3 and a p72 to choose from.
also in my country we have 98 octane gas so i think it will work well with the p72 head.

 

I'd use the B16 head and keep the compression a little lower to prevent any possible piston-to-valve issues. IF you decide to keep these pistons. We did this years ago using the same parts, and it worked, but when it came to tuning/mapping the engine, it ran best with a little less timing as though it were slightly lower compression than 13.0:1 anyway.

 

This is my pr3 head is from a jdm typer
And this is my camshafts

 

theres dudes making over 220 with ctr pistons. if you dont wanna have to run e85 then dont use them, use another piston.

 

You can run them on that RON octane. It's not E85 (or to the effect of the message high-knock resistant fuel ) requirement.

 

98 RON is not the same as 98 US octane. More like 93 for us. I think you would be pushing the knock limit with that setup on 98 RON but of course with enough timing pulled out you could probably run the thing on candle wax...

 

Thank you for your responce , i really apreciate that. Btw i will sold my pr3 itr head tommorow , naked with no valves or anything else, and i'm planing to put the itr vlaves on the p72 head ,so i have to go to the machine shop to fit them on the p72 head because as i know they have difference on the angle of the valve deck. whats your oppinion on that? itr has high flow and lighter valves than p72 valves, it make any difference on power? (sorry for my english .

 

I'm from Cyprus and we have unleaded 95 oct and unleaded 98 oct, all cars are jdm imported direct from japan if that help to compare us 98 octane with unleaded 98 octane

 

if youre from cyprus get with those dudes in turkey called PPR motorsports. i mean i see mostly k series they do but the k series setups they do are nice.

 

turkey? i'm okay , after all that they make to cyprus and my family i don't want to deal with them

 

ok cool. are you wanting to use aftermarket cams or just the type r cams?

 

i will use the typer cams for now ,a friend is selling his toda b spec cams and i'm thinking to buy them , but i think that is too much for my setup, what you guys think?

 

Spec Bs would be just fine for this setup. Get good valvetrain to match. But it is not too much "cam" for that setup.

 

nah they arent too much

 

Thank you guys for your interest and your knowledge , I will post and let you know about my project soon , thanks again
