I did a search and came up with some info about itr parts into a b18c1 usdm. my ? is what all can i put from a itr to help my 95 gsr. itr camshaft is better than ctr? i just want a car with high compression for a daily driver. iam going to port/flow the head. and i am building the block too itr pistons. any help would be great thanks or a write up from someone who has good creditability.

 

CTR pistons will give you higher compression

 

i read it gives you more but may be wrong i thought i read that itr are better in the long wrong. would itr pistons be ok with ctr camshaft? sorry nobe

Yup you should be fine...but if you're looking for high compression go with the CTR pistons. BTW do you want to use USDM or JDM ITR pistons?

 

i just searched and i came up with ctr would be to high and it would cause some problems later like clearance issues. i am going to get some itr or ctr would like jdm cams and value retainers jdm i dont for sure some said that gsr's retainers are stronger if you stay under 8200 rpm. i just want a strong all motor that can rev up quick are hear the Vtec. sorry i have a vx civic and cant wait to put gsr

People doing similar mods to their engine typically go with CTR pistons for higher compression and can use CTR cams which are slightly larger than ITR cams are for better power. Good reliability is normal from this set up.

 

so if i put ctr cams and pistons i should be ok. and is it possible to mix and match. like ctr cams itr pistons or would i loss some hp? ctr is cheaper too than itr? my plan is to get the head port and polished and get some ctr or itr cams and retainers which retainers should i get? or are they same.

 

There is a website that sells good dual valve springs and retainers for $225 shipped but i cant remember their name...but yea you should be alright with ctr pistons and cams...jhpusa.com has a sale on the ctr pistons

 

never mind the sale on jhpusa.com is over

 

thanks man

It's fine to mix and match without problems as long as you know what you're doing. Because the compression ratio will be higher with the CTR pistons vs the ITR pistons you would be losing some power if you went with the ITR's. As far as price goes I don't believe there is much difference between them. Your stock GSR valvetrain should be fine with the cams since you won't be reving it any higher than before if you're still running the stock ecu or with a VFAC added etc. Stock retainers will also be fine since you're not making any radical changes with the valvetrain/engine combination.

 

i did some searching about ctr pistons and cams in a gsr and it sounds a good and bad. if i did this would i need to change or modify anything from a 95 gsr to make it run good. the compression ratio seems to high for me. i stay in washington and dont know if i seen gas higher than 91. would jdm itr cams and pistons give me a good gain or would i ctr be better.

 

bump before class

 

well I would go with the CTR cams ideally but ITR are still a good choice, depends on what's abailable to you. CTR pistons would give you like 12:1 compression so without some sort of tuning it may not be what you're looking for. The next best choice would be JDM B16 (P30) pistons which would give you about 11.6:1, should be ok on pump gas with that, but the next best choice would be USDM B16 (PR3) pistons at 11.37:1, JDM type r pistons (P73-00) would be virtually the same at 11.36:1 but probably cost more money. The last choice would be USDM ITR pistons (P73-A0) which would give you 10.8:1. You could always use a slightly thinner headgasket with any of these setups which usually bumps compression up another .2 or so if you want to custom taylor the ratio. All the ratios I listed would be with a stock 3 layer headgasket.
