JRSC with crower stage 2's?? - Honda Prelude Forum

Ok, i'm putting stage 2 crower cams in my lude soon, and i'm thinkin about putting the jrsc in about 2 years. I've heard it's not a good idea to put a jrsc in with cams... is this true?

i'd like to know this too...

The JRSC is built to run with your stock cams only.

so it'd be stupid to get a jrsc if i already have a crower cam setup then, correct?

Might be interesting to see the results of a high lift/low overlap cam with the JRSC.. The crower cams IIRC are made for NA applications only. They could make you a supercharger cam, though.. Jackson Racing probably has some information along these lines.

you can still buff up your internals though right?

I was wonderign about the same thing before i got my lude. The thing is JR said that they tried many combos with cams and SC and it just does not work. Unless you get some custom cams made. That the only way. They did a set up of Cams and SC and it ended up loosing HP. so i'm thinking may be just may be Stage 2 is bad....but stage 1 might be ok. THIS IS ONLY A WISHFUL thinking here guy not a scientific resonse. Why am i saying Stage 1 might work...well since its almost like stock. So i'm thinking if its almost like stock..then we might be able to get something out of it. But I would really want to see JR do a study on this may be come up with a set of cames that would go with SC ...and may be give additional 10whp. That would be awesome.

The point of the JRSC is that you don't have to beef up your internals and can run it as is, just bolt on and tune. If you want to put in better rods and pistons.. then go turbo! There isn't much point with the JRSC as without a means to intercool it, compression much above it's 6psi or so is going to cause the air to get way too hot. Although I still have concerns about the stock piston rings and positive pressure, the consensus seems to be it works fine.

I was going to go the buildup route, but I'm going to try the JRSC and see how it goes. Lots of people are running them now reliably.. once the original motor is gone in a few years (and the lude is paid for), it'll get stripped and built then.

i was thinking of doing my internals so i can put on a JRSC. my lude is daily driving and i can't handle downtime, i'm not good enough to deal with turbo problems myself, i just feel its gonna be suicide if i go turbo. but this car needs to last me too. i dont wanna put on a JRSC if my motor is gonna explode at 100k miles. has anyone heard of a lude lasting long with a JRSC?

i would like to know this too..... by the way, considering i'm putting stage 2's in my lude... I'm expecting to probably run about 14.2, so what would be the cheapest mod to do next to push me to maybe 14 flat.

Have any of the naysayers here actually gone and looked at the Crower site? They have "stage 2, low-overlap, high lift" cams made for turbos (blowers too, I'm sure).. sounds interesting.

It would also be interesting to see what would happen if someone were to dial out some of the valve overlap with cam gears on a JRSCed Prelude... and yes, I know access to the cam gears is "a little blocked"

Until someone does it, guesses don't count.

I'd be interested to know how the jrsc does? What is the expected 1/4 time with i/e and jrsc?
