Hello,

Am going to put a F23 crank into a H22 block. Going to use a H22 Head and valve train.

WIll use the F23 Rods but H22 pistons.

THe share the same heights, blocks are almost similar.

My question is:

Can I leave the cams on stock position? Or i need to degree them on the new crank?

H22 crank - Stroke - 90 mm
F23 crank - Stroke - 97 mm

Regards

 

All motor gurus.... HELP

Simple question - give me the answer.

 

I am assuming you are going to use stock cams?

What are you power goals?

 

lol you are so wring that setup your piston is goint to be tou of the hole +- 0.040", they are not the same comp height they have 1mm difference

 

Ya ...good luck, gonna need a big *** HG

Degreeing never hurts, will yield better power, do it

 

Thanks for the replies guys.

Yes stock type R cams.

I know degree never hurts, but am yet to be the best at it. I know how to degree cams, have the tools and know the method but the confidence in my work is missing. Unfortunately no one else in my country can degree cams from what i know. Thus wanted to ask for a fail safe.

Power goals are not big probably just make the stock power am happy.

Its all the parts lying around the house. I know the pistons are -0.039, Got the HG 0.080 which leave the squish area at 0.041. From what i read on V8 forums that is very acceptable for a street engine. I know honda is no V8 and yes thick gasket is bad detonation issues etc.

But like i said i got everything lying around, might as well experiment get some education as understand what she says.

What do you think guys?

Regards

 

first of all, welcome and your country is beautiful!



next, you need to degree because just like when you started learning to tune AEM, it took some time to learn, now its time to learn a new skill that you will help you in the future.

there are a few good threads about degreeing cams on here, but I do not have the time to search them for you. Maybe they are stickies?

Or just run it the way it is, I mean, afterall, they are stock cams. If it blows up, it blows up.. What can you do?

One way it's hard and long but you will learn something. Other way, it might still work out all right but it's by cutting corners. Because you are running stock cams, its possible that it will be fine if you dont degree it. But over the internet someone saying do this and that, that is pretty risky because if I am taking risk to blow my engine up, it might as well be my guess. So if you are set on getting the engine running without degreeing it, leave it in stock position and say a prayer!

best of luck

 

Sir,

Thank you for the grand welcome, yes the island is very pretty. I hope you come visit someday, cause obviously we dont find it as beautiful as you do.

The engine i have presently, I did degree the cams shafts. I have a set of crower cams on my turbo g23. I use the centerline meathod to degree.

This engine also have a F23 crank, they were 10 degrees off. I corrected them by 5 degree on each cam. Now on this engine i have the cams at

3 degree retard on intake
3 degree advance on exhaust.

The engine seems happy with this setup. I am happy too, still tuning the turbo engine in slowly with the little issues. So dont have numbers yet.

WHat do you think of my cam setting now?

The whole reason for this thread was to make sure that if ever even after a few learning runs i dont get the cams right on the new engine, I can always set them stock and say the prayer.

Regards
