Re: Dyno my B20a Turbo
 

that's gotta be fun to drive.....is it a completely stock motor?
how much boost?

Re: Dyno my B20a Turbo
 

Just Cams and turbo 8)

Re: Dyno my B20a Turbo
 

That accord b20a is a pretty rare engine, thumbs up for doing something different i had a b20a5 turbo charged at one point, things make sick nasty tq!!

how much boost? im guessing 8psi or so?

Re: Dyno my B20a Turbo
 

7.6psi

Re: Dyno my B20a Turbo
 

i got one of those sitting out in my garage

Re: Dyno my B20a Turbo
 

Why is the smoothing on 5?

Re: Dyno my B20a Turbo
 

HOw many headgaskets per day did you change in it??? :8

Re: Dyno my B20a Turbo
 

12:1 afrs eh? Is that safe when boosted on a honda? I aimed for mid 11's to low 11's on my car just to be on the safe side.

Re: Dyno my B20a Turbo
 

despite being a non mls head gasket the accords seem to hold boost just fine. my buddy accordepicenter has yet to pop a gasket and run as much as 13 psi on a stock motor on his a20 no problems at all. and we just a put together a fully built a20 for him looking to make 500+whp still has the stock composite gasket in it too. besides on a stock motor I would rather the head gasket be the weak link then the ringlands

Re: Dyno my B20a Turbo
 

well just had a set back my wastgate failed and it hit 20+ psi and my headgasket went bye bye i have water in 1 and 2 and it blowing exhaust out between the head and the block by the turbo :-[

Re: Dyno my B20a Turbo
 

with that composite HG at least it would go before anything else.

and what kind of WG was it :l

Re: Dyno my B20a Turbo
 

The head gasket was AJUSA and the wastegate Egay i put a new spring in it and i pinched the a hole in the diaphragm :l

Re: Dyno my B20a Turbo

10--6---2---3---7

9---5---1---4---8

Re: Dyno my B20a Turbo
 

Your problem is the composite headgasket.

Re: Dyno my B20a Turbo
 

That the only choice i have for a head gasket besides cooper and cooper leaks.

Re: Dyno my B20a Turbo
 

Fixed

Re: Dyno my B20a Turbo
 

Keep telling yourself that.

Re: Dyno my B20a Turbo
 

I did not even know that honda uses those crappy headgaskets.
I spent 5 minutes looking for a mls headgast for that motor, came up with nothing. you might have to get it custom made. cometic

Re: Dyno my B20a Turbo
 

HOLY ---- MR LINDSAY ARE YOU TELLING ME THAT HE CAN GET A MLS HEADGASKET???


Nah, he's not listening.

Re: Dyno my B20a Turbo
 

nope thats not what I am saying, I am saying its not as common and might take some hard searching and asking around.

this is all I found so far. http://www.store.partsdinosaur.com/product1679.html

Re: Dyno my B20a Turbo
 

Haha.

Dude seems pretty alright. I wonder if he and Craig get together and drink beers?

Re: Dyno my B20a Turbo
 

thats why you should set the boost cut limit at a safe setting setting

i know my boost cut saved my b20b/b16 last night, my wastegate diaphragm was blown and i hit 12 but boost cut saved me

Re: Dyno my B20a Turbo
 

I called them the only choice i have cooper and they said it will leak water down the road.

Re: Dyno my B20a Turbo
 

Whomever "they" is, please give me their number so I can personally tell them that they are flaming faggots who need to stick to selling goped parts with no technical advice involved. You will seep tiny amounts of oil and coolant over time with a copper headgasket. It is not a leak, think of how a valvecover sometimes gets barely moist with oil right at the seal and airborne dust adheres to it and makes it "mossy" and inch or so around the gasket seal. That's the sort of leak you deal with, it's practically nothing. It is not leaking coolant as you go down the road. ::)

Besides, you can get an MLS gasket for your engine. This is the third time I've told you this. Why the ---- would you want to run a copper gasket when MLS is available??

Re: Dyno my B20a Turbo
 

MLS is not available for my B20a. My B20a is not some as the B20a or the B20a5 that came in the 88-91 prelude here a pic of the head gasket
