high compression mini me?????
 

i have a high compression d16a6, i want vtec, and i can get a y8 head, with my domed pistons i dont know if i will have sufficient valve clearance. does any one know off hand if this insanity will work? if it does this will probably add 20 - 30 horsepower. any input is appreciated.

thanks

Well, what is your compression right now?

Re:high compression mini me?????
 

11.5:1 is my compression. like i said.

Re:high compression mini me?????
 

i have a friend with the same set up..his d16y8 is milled also...20-30 horsepower from a mini-me...maybe 10 horses.

Re:high compression mini me?????
 

is your friends mini me a 11.5 :1 compression d16a6 block with the y8 head?
if so what is his horse power roughly, and did he need to do any thing special?

Re:high compression mini me?????
 

i dont know how much compression he is running..but his car wouldnt run anything quicker then a 16.3 in a 1990 CRX

Re:high compression mini me?????
 

with my high comression i have to wory about vale reliefs in the pistons, and i dont know if the angles are the dame from the a6 head to the y8 head. and i know that i will be abel to run a hell of a lot better than a 16.3. with the high compression i ran a 16.2 on bald tires, i smoked my tires through 2nd gear.

Hmm, I reread your post on this thread, and I still dont see where you posted 11.5:1 ? that is why I asked.. ???

Anyhow, if you were to put a Y8 head on your a6 block with those pistons you will have a compresson around 13:1
Good luck even running pump gas with compresson like that, I would clay the engine for clearences, god knows if the valves will hit or not, especially when vtec kicks in.

yah, i will clay, and i think i will run a thick head gasket. mr gasket makes stakable gasket sets, so i might buy 2 sets and have a huge ------- head gasket.

Re:high compression mini me?????
 

u might not gain too much power doing that. U have higher compression meaning more power. and if u add a y8 head and lower compression you might just be making the same power but with vtec. see what im getting at?

Re:high compression mini me?????
 

im not gonna lower compresion, if any thing it will get higher.

Re:high compression mini me?????
 

When doing that, you will be more prone to blow the headgasket out.

Re:high compression mini me?????
 

I dont know if this will make sense or not, but why not take the stock one out, and put the thicker one in? Does that make sense or is gasket stacking better? ;)

Re:high compression mini me?????
 

I know when i did my mini-me swap my compression jumped. I had the same compression as a car that was juiced up.

Re:high compression mini me?????
 

im gonna cc the heads and see if they are close to the same size and shape. i hope i can make this work.

Re:high compression mini me?????
 

what do you think a thick head gasket will do?
