Hello,

I want to know if anyone makes Thick head gasket for the F23? I was wanting a thicnkness of 0.51 or so.

Want to drop the comp ratio so i can push some more boost on our local crap fuel. Am i doing it right?

I tried calling cometic they said they dont and custom would need tooling charges which are like 2000$.

Anybody else who can make this or help?

Regards

 

Double stack dat joint you'll be set dog.

No jk lol I don't know maybe someone makes a thicker gasket. I really don't know why you would want lower compression the F23 is not a high compression engine.

 

Uh, maybe he had his parts machined so it upped the compression and he's compensating for it with a thicker gasket?

 

Sorry dint mention am running k20 pistons with a -6 cc done on f23 rods. Gives me 9.88 approx static.

Thus was a drop to push more boost.

Regards

 

I could have sworn even OEM K20 bumped compression up more than that. Anywho, why not resort back to f23 pistons?

 

I know, these are low comp k20 pistons that is why i use them.

And these are forged pistons for turbo from arais, f23 pistons wont hold the boost and will blow ringlands.

Regards

 

when I got my first head gasket for my f22 from autozone, it was about twice as thick as oem honda to compensate for machining services. it was a blue fel-pro hg and the middle layer was about .030. I don't know the exact specs of it but I do know it is thicker. maybe they have for f23 as well.

 

Hey,

Thanks for the heads up, I checked the autozone website.

they list Fel Pro part number 9958PT-1 for the F23, the design of the gasket looks good. But no where they mention the thickness.

I tried even the FEL PRO website but the thickness is not mentioned.

Did some calculations a 0.081" gasket would be perfect for me would drop me down to 9.06:1 approx. Any ideas?

Regards

 

You may want to consult Bisimoto on that..

 

What kind of power are you planning to make? Not sure about the f23's but there have been a few essentially stock F22 blocks (just headstuds replaced) that have made closer to 300whp reliably. I don't see why the f23 can't handle the same. There's actually a guy on hondasociety who has been boosted for a few years now and took it from 15lbs to 17-18lbs to attempt to blow it and it still wouldn't let go.

 

A data point you may want to consider.

The problem with a thicker head gasket is that the area where the gasket O-ring is between the head and block leaves a dead space where the air/fuel will not be burned properly. It leads to detonation issues and poor running.

Squish, the amount a head gasket compresses, is best to be minimized as much as possible. If you need to reduce compression purchase the correct pistons.

 

9.88:1 compression is not all that crazy for boost, given you use an appropriate grade of fuel for your power level and have a good tuner.

I would run that compression personally and an OEM mls head gasket. Check out AFAccords turbo f23 thread in the FI forum... made great power and 10:1 compression.

I am just over 9:1 compression on my f22b1 and would not hesitate to run a slightly higher compression than I am now in the future. The key is tuning, good management, all the obvious supporting parts to make a quality setup, and select a fuel (premium, e85, etc) that will support it.

 

TwkdCD595,

I thank you for your reply, i have read AFA's build a number of time for references, he is making superb numbers.

The problem for me is that in the country I live, we dont get Premium or E85 fuel. We get only 85-88RON normal grade of fuel.

I think 10 psi is the most she will take on that fuel, what do u think? What do u think of adding a aqua meth system to make up for the bad fuel?

Regards

 

Ouch, yea 85-88 RON is quite low. I am not a tuner so I would not be comfortable telling you what to run on that lower quality fuel. Seems very low octane for any decent amount of boost obviously, which I realize now is why you are concerned.

Methanol injection would be a good option if you can go that route.

 

Thanks for understanding where am coming from.

I was looking at the new aem water meth kit, loooks very nice and at that price its reasonable. or devils own.

But how safe is it to make the mixture at home? as am sure i cant get it locally.

Regards

 

The f23's are great engines despite their lack of power from factory. Their great for boosting because of their Iron sleeves. Iron sleeves=happy boosting v.s. FRM Sleeves=bad for boost. I wouldn't run a crazy amount of boost but she can take it!
