I had a custom head gasket made for my B20B - this one is 2mm thick, and will drop my C/R to about 8.5:1 with stock B20B pistons and rods





does it look okay, construction-wise? the shop I had it done at is the same shop that makes custom head gaskets for JUN Thailand. I used their headgaskets in my D16Y8 turbo too, seemed to hold up great. Never blown one up.

 

Yeah man that looks great. Worried about cracking them b20 sleves? he he

tHE word worried doesn't even begin to describe the amount of fear contained within me from boosting this engine on stock internals!

HE HE i hear that, but you will be okay, your not some dumb kid who doesnt know whats going on. Is this the car that has the LINK management? You have so many cars i lost track

Rob

 

Yes, its got the Link standalone ECU with an A/F Lambda meter and Knock meter. People here are saying that B20B engines are sensitive to detonation, so I guess i'll know about it first with the things I have, before something goes wrong. I hope..

 

looks good.. i have a greddy 2mm on my d16z6 anyone know what it could have droped my compression to?? i did a test and the cylinder compression was 205 before and 175 after..

 

anyone???

 

where did you have that made, and how much did it cost ya?

 

What camera is that? I can see germs on your fingers

 

I got it made at a shop over here in Thailand. Top quality construction, custom-made, any thickness you desire for any engine.. whether it be a D or B series (or any other manufacturer for that matter).

Do I sense that people are having interest in purchasing head gaskets from me now?

 

It should have dropped it from ~9.2:1 to ~8.5:1

Sonny

 

Even with 8.5:1 compression I still cracked my b20 sleeves

 

Were you running with a blockguard?

 

tuning

 

..might be because of the mismatch of head chamber 81mm & cylinder 84mm. I still have this theory that any long stroke motor is "edgy" and sensitive to detonation.

 

*nathan feels very uncomfortable whenever he hears comments like this about turbocharging b20b engines..*

why do i regret buying this engine...

 

I hear ya - I'm running a B20B in my GSR ever since my 18C got destroyed and now I'm getting more and more nervous, but I figure with a standalone and decent tuning I should be OK, particularly since i'm not running any more than 8-9 psi. Does make me want to go out and double-check that my base timing is still setup correctly with the AEM ecu.

 

Nathan should relax and take it easy , he boosed a D series like crazy every day when the D series sleeves are good up to 20 psi supposely and you took it waaay beyond that. you should not be worried of the b20

 

what is the cost of your custom headgasket?

 

It was a *little* bit cheaper than a new cometic headgasket. I could make them for you guys if you wanted them, but once you add shipping costs, i'm sure you'd be better off just getting a cometic headgasket locally

 

My B18C head has already been matched to the 84mm cylinder in order to drop the compression even further.
