Seeing videos pop up online with people ripping to 8000+ gives me grins :)

The camshaft tuning is pretty straightforward. You'll see gains even if you simply adjust AFR and VTC limits. Easy. There is more power to be found if you are proficient with Hondata. I think the PID tables to give you a lot more control with the XDI. I haven't had a lot of feedback on...

It was fine at 400whp on the stock pump and injectors. I am pretty conservative. I don't tune stock ECUs every day and don't tune cars for customers so it takes me more time but I make sure that whatever we do on the dyno a car can go run 40 laps WOT as a person would actually use it...

CAMS are packaged and started shipping today! FINALLY!!!! Thanks everyone for your patience. I know it has taken longer than anticipated.

I am not on the forums much. This is the only thread I have checked in months. I wish I could spend more time here, but I have engines to work on. I'm just here to update people on the camshafts. Sorry for the lack of response for your stock engine. I really only want to make suggestions...

Sorry. I send a recommended oil sheet with my engines. It varies with application and engine spec. I wish it was an easier answer. This thread is about cams.....

4P TR2 Drop-In Camshafts - K20C1 Type R – 4 Piston Racing 4P TR3 Racing Camshafts - K20C1 Type R – 4 Piston Racing On display at HDAY this weekend in Maryland, along with other cool new Type R stuff. Give me a week or so to ship as we are traveling this weekend and won't be back here...

Camshafts are here, and will be added to website any day now. Probably after we get back from HDAY. TR2 and TR3 Just a heads up, there are limited quantities because I've committed some to engine builds. Not preselling....all done through website.

It is. You supply 100psi compressed air to the cylinder like you would for a leakdown test and make sure the valves are closed on that cylinder. You can then compress the valves with a spring compressor like the universal snap on unit. Its not something I've done for many years but people do...

I was hoping to have many sets of cams ready to go by now, but we do not. We are many months behind on our normal K20A based cams and unfortunately gets in the way of production for these. They are produced on the same equipment and our demand doubled this year for those. I hope to have some...

That code is unrelated. the only codes that have come up are if you.... 1. Limit VTC mechanically and do not limit the values in the ECU. 2. install the cam chain improperly and engine isn't in time

Right now you pretty much have to get the Garrett whether you want to or not. Borg Warner has supply issues. Bummer....because I think its a higher quality turbo that under the same conditions will last longer. They produce similar results...maybe a touch more power from the 660.

I think 8300-8500 is more realistic with a smaller and responsive turbo that's fun to drive. I turn mine in that range on the small turbo and its a blast. Of course you can put an 800hp capable turbo on the car and build boost up as rpm rises and have it climb to 9000 rpm. It will 100% do...

I think the biggest thing you'll see on stock engines being pushed too hard on RPM is valve float. Pay attention to dyno graphs and you'll see they get pretty choppy up there past 7200......that's not good. The valve is out of control.

250hp per cylinder and "safe" is pretty bold :) That is a race engine for sure, and lots can go wrong whenever you put that kind of strain into an engine. If all things are right, and the tuneup is good....they can last a bit but anyone trying to do that in a street car will soon learn about...

In stock ships right away. We can swap you for your core.

By the way....if you are tuning with larger turbos at higher boost, start easy like you know you should and work your way up. I typically start at 14-15 deg then step my way into it with these heads. Keep an eye on your cylinder knock, temps, and go with your feel when you drive the car. We...

I've been hearing some rumors here and there that there are some camps going around telling people that the CNC cylinder heads lose horsepower. Guys have gone to the extent of removing their heads and going back to stock. People HAVE made good power and gains on them to squash that....so...

Not related to this topic.... @Mishimoto I put one of your intercoolers on one of my cars for testing cams and it was the best that we tested. I had 2 others that didn't work as well. My guys commented how good the fitment and quality was. Unexpected surprise....good work.

We are updating the packages on the website to include cams. We are going to differentiate the options for "stock replacement with strength upgrade", a performance upgrade, and a max effort race setup for big turbo cars. Not everyone needs the same package and I think we have a better handle...
