I searched around but didnt really find what I was looking for.

I have a B16 I wanna boost and I want to use a CERTAIN piston. I only want to use these particular pistons, ANY other variable can change. The problem is these pistons are only made as forged replacements for CTR pistons, yielding in a b16 an approx. comp ratio of between 10.8-11:1cr.

My first thought was to use b17 rods, since I believe those were a little shorter, but to no avail.

My second though was to use a THICKER headgasket, either the Cometic .074 or the Buddy Club 2mm, which I guess effectively raises the deck height which is how it lowers compression.

However, I see quite a few mixed reviews on this and I dont understand why. Other than one decent argument that was made about these HG's not being readily available in case I need a new one, I dont see this wouldnt work.

So...

well because you now have these certain pistons...increasing the distance the HG needs to take up is creating a weak point.

The Hg works but isnt the best way..

out of curiosity, why do u want to use those "CERTAIN" pistons? Are they already in the car? did u already have them? i just dont see the point of using a piston of such high compression when you want to turbo your car.

They are the only B series pistons made by a company that I want to use.

I dont want to either, but it is what it is. I have contacted them and these are it.

95dc2teg

why not consider a different company? they are many great ones out there. theres always a choice....

kicked25th

I am set on this one.

I dont want your typical Wiseco, CP, Ross, SRP setup like EVERYONE else.

Plus, they are, as far as I know, the only company that uses a special forging process I want.

Enough about the pistons though. Why would it be a weak point? Im sure a proper seal would be created, so I dont see the downfall.

You will be fine with a 2mm gasket and some arp headstuds. I currently run a 2mm cometic gasket and I have boosted up to 32psi without a problem, 4 yrs and counting...

Whats different about their forging process, that makes you pick them instead of the others?

ok you'll never hear the end of it if you dont tell us what they are, at least the brand if not the "specialness" of them.

kicked25th

look. its a piston company. They only make 1 B series Piston. Its a b16b replica. Thats all that matters.

This is suppose to be a thread about the reliability of thick head gaskets. Thats all.

b16a4

why is it such a big secret

kicked25th

not a secret I just dont see the relevance.

kicked25th

thanks for the help. Im gonna go with a .062mm and ARPs with Copper Spray (recommended by tuner) though it does bite that they only make all motor pistons.

i wonder if the huge dome will be a problem

i want these pistons..what kind are they?

they are a "replica" company, they make **** that resembles quality lol. dude the guy isnt going to own up to the name, its a waste of time.

i've been needin a reason to use this lil guy

Using an uber thick gasket like that to lower compression is far from ideal. It makes the engine more prone to detonation as the proper quench height around the outside of the piston to the head can't be maintained.


That being said, maybe "everyone" else uses CP/Wiseco/JE/SRP for a reason?????

exactly what he said. i just dont see the logic of getting high compression pistons, then try and lower the compression with a thicker headgasket. just get a lower compression piston to start off. i just dont see the logic in it IMO. but i know that it is ur car, you can use whatever piston you want. Good luck on your build for realz though.

kicked25th

trust me this situation is far from ideal in every respect, but it looks like I have come to terms with the fact that I will end up going with a Wiseco or maybe Endyn (which I believe are made by Wiseco) piston.

wow.

kicked25th

not for compression I meant in terms of combustion, which was already addressed.

[/QUOT good job

agrn93ls

it would just be so much better if you used the "right tool for the job" if you go through all the headache to make something work that isnt intended to do what you want it to do you will be disappointed in the end.

i understand what you are getting at. go with wiseco's would be my advice, that i know of they are the only piston that uses an offset wrist pin and honda uses offset wrist pins on their factory wrist pins and it gives a leverage advantage on the compression stroke, from what i understand anyway.

kicked25th

I understand what you and everyone else was getting at.

I got a helluva deal on those pistons and I have seen them hold up in high comp turbo setups people have done, but in the end I realized that it just isnt worth the trouble.
