I have read from previous posts in the past that Crower cams have a slightly better performance than Type S cams. I mean, the CR for the Type S has been beefed up to 11.0:1 and that's impressive enough for a stock car. But, with that in mind, would there be slightly more gains say if you rebuilt the block with Type S internals, but put built the head with Crower parts? I know there are pistons for an 11.5:1 CR, but this is assuming you just wanted to leave it at the Type S spec, just to say your "stock" Prelude is basically the same as a Type R Integras CP (11.1:1).

 

just for the record the jdm type-r has a 11.1.1 comp ratio the usdm is 10.6.1

 

My car is in the shop currently getting a rebuilt block with .25mm OB Type-S pistons (ceramic coated by PowerDyn) and Eagle rods. Honda rods are weak so i wouldn't go for the type-s rods. Get Eagles, Endyn uses Eagle rods. With a fully built Crower head and a some nice pistons/rods, you'll definately benefit HP&TQ. I'm selling my Type-S cams for 500, they have less than 500 miles on them and are in mint condition.

 

Well, Crower makes about 4 or 5 different variations of camshafts for the H22A..

They make "Type S" replica cams.. that are no different than the JDM Type S cams.

But they have Stages 1, 2, and 3. All have a much more agressive ramp speed, mainly top-end 4000+ rpm power at the cost of a much weaker bottom end power band.

To answer your question, you could use Type S parts with Crower cams. However, depending on the Crower cams you use, you'll more than likely have to put in beefier valve springs/retainers to accomodate the new lift and durations on the more agressive Crower cams.

Stage 2 Crower cams generate 15 to 18 horsepower with basic bolt ons, and then you can add the Type S pistons to give you that 11:1 compression ratio and achieve maybe 10 more stallions.

you have any info to back up that claim of 15-18 hp w/ boltons? not saying that youre lying but that sounds pretty good.

 

I am doing a buildup right now close to what you are asking. I have I/H/E and pulleys now. I am getting Crower stage II cams, Type S pistons, SkunkII cam gears, and VAFC. I hope to get about 190+ to the wheels with this setup and proper tuning.

 

I didn't know eagle made rods for the H22 - website?

are they better then crower rods?

 

i have crower stage 2 cams, crower cam gears, crower rods, crower valve springs, and je 9:1 pistons.. i'll let you know when i get it dyno'd what kinda hp i'm making without turbo or shot

Yeah here's my back up http://www.crower.com

They got dynos of their cams making 22+ horsepower
