Hi
Just wondering if anyone has tryed this? CR is around 11.5 can you run 92 pump gas on this setup? How much power on a stock Si are we talking here?
ANy help would be great.

not sure about the power...but a few people have done it that i've read on here....i think you have to bore the block .04 or somethin like that

Get up with tony(the real time) hes done this.....hell know what to tell you..

[ballade]

Tony can you help a bother?

Do a search using the term "Hydra".

Kirk Olson AKA gtpilot, did a EW block with a D16a1 head, teg pistons, etc.
Its a long read but very good in detail of the build.

He's talking about keeping the si head, so you get hella higher compression, i've been wondering about this myself too, compression is fun (as long as it doesnt blow up)

[Doodson]

I have done this for many years on my race engines and the only thing that need to be done is the stock block needs a .040 bore to fit those pistons. I would also recomend not shaving too much off the head. I always ran a 94 octane gas with these engines. I also would replace the rod bolts with ARP ones and get the rods resized while your at it. Any good machine shop will be able to do a boring and resize rods

[stevo911_]

would a cr this high be ok on 91 octane as opposed to 94? (theres not many gas stations around where i live that have 94)
also what kind of power do you think you'd be gaining over a carbed dx motor (if you have the si one carbed as well)

just thought of another question, whats the difference with the 88-89 pistons, what compression will those yield?

[projEKtjokes]

This should help you out a little. . .

[Doodson]

I always ran the 86-87 pistons with no problems but people have run the 88- 89's aswell, you just need to check clearances

[crazi-85crx]

Here's a shot of my 1.5L block with 86-87 Integra pistons. The 88-89 Integra pistons give about a 0.4 increase in compression, if I remember right. But I couldn't find any at the time.

[crazi-85crx]

Also, the 1.6L D16A1 rods don't fit the 1.5's crank, so you need to have the piston heads pressed off the 1.6L rods and pressed onto the 1.5L rods.

ARP rod bolts are about $45/set, and then it's another $20-50 to have all the rods resized.

[stevo911_]

how much power do you guys think somethign with these pistons would put out? (with just the piston swap and intake/header/exhaust)

[Maine_Honda_Racer]

When you all say rods resized, I hope you might elaborate on that, do you mean just having the d16 pistons put on the ew rods? If so thats not too bad, then you can use the 1.5 rods and the 1.5 crank. That would be fairly simple......
