I have a JDM b18c R motor. 11.3 compression. .25 over bore honda oem piston. Skunk2 intake manifold. 98 spec headers. whale ***** intake. spoon n1 full exhaust. etc with the skunk2 pro1 cams and cam gears.

I have a p28 tuned from phearable at the moment and have had hell gettin the car to idle properly and jus have become frustrated. I have -50% at idle for my air fuel ratios to be at low 13s.


I am thinking about taking these cams out becuase I have a feeling my compression is not high enough. im looking into buyin tuner series cams.

or


buying hondata and tuning it.


I think these cams may be too big for my application


what do you guys think

 

Your compression is a tad bit low. Did you get springs and retainers? If not springs retainers and Flat faced valves and a tune will fix your probelms

 

Your Compression is fine for those cams.
They will make Great power on the R motor.
Get it tuned. Thats your only problem.

THAT and the fact you didn't degree cams just like 97% of the other people who put cams in they're motor.

since you seem to have a better answer what did you find? I dont want to start a war. I just want to friendly. I know im not an encyclopedia of knowledge. Don i know you are a reputable guy but why cant you just say hey your retarded this is the right answer instead of treating me like i have a complete research and development lab in my house?

The point is, if you can't back up your statements, you shouldn't be making them. I assure you Don can back his up.

 

Im not saying he cant. And i know Don is a very reputable guy. From my little experience I know that bigger cams like to have more compression or displacement. Im not very experienced either. Im just trying to pass out what I do know. And if its wrong just correct me and ill be on my way.

 

A simple search on here for pro 1 cams or checking out Skunk's website will show you that he has ample compression for those cams. They are well suited to 1.8L engines with compression ratio's of 10.6 and up.

The op's problem is simple. He probably installed the cams without degreeing them in which is known to be very important on those cams, to get them to idle properly. He's also probably running on a basemap which is intended to get your car started and off to a tuner. He needs tuning if he wants those parts to work together properly.

A stock GSR with 11.7-1 will make more BHP than stock compression. Pro1's with 12-1 will make more than 11-1. Pro1's with 11.3-1 will make more than "R"'s with 11.3-1.

Honda-Tech - READ THIS^^^.

I don't want to see anymore "this cam_______ loves compression..." That **** drives me nuts.

(not taking shots at you horse)

To the OP, get tuned asap and you will love your cams.

 

OP, like others have said, you have to tune your engine to get the most from those cams.

Don't think about getting it tuned, go do it.

 

I have a stock gsr with pro1's and it idles perfect. Just like everyone else is saying just get it tuned and degree the cams. You will be happy.

 

yea i have dual valve springs and retainers.

This is my problem. I forgot to mention that I live in The Bahamas and we have no dyno and nobody that tunes standalones chrome or anything. Everything is from the states for us.

But yes I agree, I need to degree the cams in. Skunk2 reccomended a degreeing kit from xenonchron but I find it extremely expensive. Im pretty sure that any degreeing kit will work. You agree?

If you have any other comments for help id appreciate it... anyone

Skunk stg. 1's would be as far as I would go, with a possible .5 bump in compression. That could be adjusted with a decent wide-band. Timing and fuel pressure, a chip.
