I'm getting the head ported and polished. But next I'm getting new cam shafts.
Here's the catch. I got prices from Crower, JDM, and JUN. With my budget and info It looks like I will be getting the JDM, Type-S cam shafts. The thing is with the Crower and Jun you need springs/retainers. But the Guy from Jun took it to a new level. He told me the people that have Crower and other Cams need a new ECU and most people don't know about it. They are messing up their cars in the long run especially with the Jun set up. The guy asked me what Fuel Management system will I be running. I was like ? He told me I need to get the ECU remapped and that he sold a package for 3,812 dollars. He said without the new ECU when the VTEC crossover point hits the ECU will make the car stall because the ECU thinks it's running to lean and will stall/bog until the sufficient amount of fuel is added and then will run normal. I asked will a V-FAC help he said no not at all. So my question, is he telling the truth, or was he just trying to make a sale? What is the best way to go in terms of performance, and money/and dependability?. Your help/comments will be appreciated!

 

It depend what stage Crower cams you get. With stage1 you don't need the valvetrain upgrade. With stage2 and up you do. Since you are talking about 'having' to get the springs and retainers, I am assuming you want their stage2 cams at least.

I have stage1 cams with the valvetrain upgrade (this gives me the option of being able to raise my rev limit if need be with a standalone or hondata, but that's another matter). The vtec hits hard and I have perfect idle. I've read some posts by users of stage2 cams and they also have no issues w/o a new ecu. Perhaps the guy is talking about racing cams or is just smoking something. You should ask him.

As far as perforance with dependability, I can't say since I've never seen the Jun one at work. I can tell you even with my stage1 cams (skunk2 gears also), it really made a noticeable difference for usable power throughout the rpm range.

 

Yea, their are some stage two crower cams that dont idle correctly, they dont have the idle lobes. I think the cam is from 1100-8200rpms, but you can get the stage two crower cam that goes from idle to 8000rpm, so even if you still ahve to deal with the rev limiter, you can take it all the way up to the fuel cutoff and still be gaining power. I am still new at this, so if I am giving out flase info, someone can slam my head into a rock.

 

id wait for the skunk2's and see the dyno numbers on them..

 

Skunk 2 said February-March is when they will release their cams. So are the JDM-Type-S cams a waste of money?

 

That is total BS. no truth. Get a V-AFC so you can lower the vtec and throw in fuel. The only thing I would do with the ECU is eliminate the rev limiter. But only with a balanced motor. He is trying to make a sale. Also look to webcams.

Oh and the jdms are a total waste of money

What are webcams, and why are JDM cams a waste of money? Aren't they as good as the rest?

Webcam is a camshaft company. JDM prelude cams don't make enough power to justify taking the time to install them.

 

that's what I'm thinkin.

 

Thr Crower site lists (2) Stage 2 upgrades. The first one does not change the 'pre-VTEC' lobes of the shaft at all only the VTEC lobes. They also don't require new valvetrain or ECU if you are on a budget.

 

putting cams in the h23 auto trans prelude?..would there be any significant change in hp?...is it worth the time and effort in the installation?...whats the good and the bad aspects of it?....any info would be great...

 

OOHLAH, are you ever going to get back to me regarding the wiring harness? I see you migrated from Preludeonline.com to here, I don't want to start saying that you ripped me on that transaction.
