Im parking my car out for the winter and trying to figure out some good set ups for the top end of my itr. looking at getting all new valves, springs, retainers, camshafts, cam gears, intake manifold, and throttle body. Just seeing if any1 knows what goes well together? Budget is around 2000 but i do have all winter to get more money.

 

Send out your cylinder head to a reputable shop like RLZ or CC Cylinder Heads.

Get a set of Skunk2 Pro1 or Pro2 cams with matching valvetrain.

The rest of the money should be used for a good tune.

You should be happy with the performance from that.

 

should i get oversized valves or stay with stock. the car doesnt get over 5k a year on it i usually have it parked.

 

You don't need to replace your valves. ITR intake valves are alrady lightweight and flow better than standard B-series intake valves.

Oversized valves, while they do improve the potential flow through the motor, create headaches when large cams are used. The valve-to-valve clearance on the Skunk2 Pro-series cams are already tight using OE valves, +1mm valves would be even more burdensome to set an ideal EVC/IVO.

 

Everything ^ said.

 

Sell your ITR head (just as it is) to some fanboy and get a b16 head for your build, then put the extra money towards a programmable ECU and tune (or porting your intake mani). Since you are going to port it and replace the entire valve train, the ITR head has no more value to you as a core than a b16 head.

Use a reputable porting company and drop in a set of Skunk2 Pro series cams, tune it and have fun.

Best of luck with your project.

 

skunk2 parts suck step it up to Toda parts

 

Pardon? And this is based on what experience?

TODA has not released a new part for a B-series application since the late 90's, and they are no longer a top performer. You can get better performing parts, with better quality, and better customer service, for half the price.

Skunk2 might not win you a "JDM Sh0w-caR BliNGity Bl0ow" award, but it will make more power than any TODA counterpart, and if anything happens, they back up their product 100%.

The highest HP B-series motors use a select few parts, none of them with TODA anything.

 

That's mainly because TODA doesn't focus on top-end power parts, they were always specific to circuit racing anyway. I know I'm a TODA defender until I'm dead, but that's because they didn't NEED to develop anything else since 99. It's more of a "if it ain't broke, don't fix it" policy. Hell, I'm selling my other cams just to go BACK to TODA. That company hasn't failed me yet in 10 years. SKunk2, Jun and Buddy CLub are the only other companies I'd deal with.

 

skunk2 stage 2's are supposed to be equivalent to jun 3 camshafts. There is noway that skunk 2's can compete with jun 3's. Based on personal experience. If i took everyones word for it would have never known this FACT!

 

Absolutely, and that is where their development was focused.

With that said, Skunk2 Pro-series cams have made more power on the low cam and the high cam on every cam test I've seen, including the 6 sets of cams that have ran through my 2.0L. New understanding on ramp angle, tapered retainers to allow for more lift without rocker contact, and general improved valve timing has all led to better performing parts at all engine speeds.

Also, all of TODA's parts were developed for racing series' where displacements were limited to 1600cc or 1800cc, and typically do not perform well on the larger motors.

Not taking anything away from what they have accomplished, but they are generally outdated with the current B-series scene.

PS - You should really try some Pro-series cams

 

but would pro2s pass emissions? With a VAFC maybe? At least to idle it into the shop?

 

what ever happend to rocket motorsports?

 

Sorry, but I can't think of any cam that will pass emissions with just a VAFC for tuning. Every car I've tuned that runs Pro-series cams idles and warms up like stock with barely a hint of cam. You will never realize the power potential of any moderately sized cam (or bigger) with just fuel control.

Rocket is still around. He is banned from H-T. There are plenty of distributors on H-T still, and he is still posting on other Honda forums.

 

crazy ive been out the loop...

 

Hmmm. So would it idle around on a stock ecu? P73 BTW. All im trying to pass is OBD2 plug in not any smog, just the CEL crap.

I was wondering about rocket I couldnt find anyone with his crap. Guess Ill search the market place some more.

 

contact ALL MOTOR or Clean Rice or Aquafina on this board for Rocket parts and information.

 

the rocket m22's were good from what i read... but the actual material they are made from is'nt the best quality

 

They are good and no issues with the material they are made from. The only problems came from people using stock cam bolt torque settings instead of the lower required 22 ft lbs which caused a couple to break.

 

Wear issues? My old H22 had lobe and rocker wear like crazy.

 

I thought cam cap bolts were 20ft/lbs?

 

H22's were known for for top end oiling issues and the lack of zinc in the new oils was a contributing factor in many of those cases.

 

not cam cap bolts, cam GEAR bolts.

 

good info....
i know this is the all motor area but.... a final drive upgrade would help out your car alot in addition to ur headwork is anything wrong with your head as is now? or do you just want more power

going from a 4.4 final drive to a 4.9 is like adding 30hp (dosnt add HP) but adds alot of acceleration and torque

 

My wear was nuts, your finger nail would catch on both the rocket and lobe. I tell H22 kids that come in to my work to get some of the zinc old. They never listen even after I tell'em what will happen.
lol IDK what I torqued those down to, I just tightened them down :s
