Just curious if anyone has tried to use the Darton Dry Sleeves in 87mm std bore only option you can do and put some power to it, turbo wise with forged pistons? I know it is not smart just curious who has used them...

 

ive made 750 whp + 70 shot nos with bullseye S375 turbo
my block is JDM H22a closed deck

 

I made over 850 on those sleeves and my stock sleeve closed deck with mahle pistons makes over 550.

 

Really? We are talking about the cheap replacement dry sleeves here...

 

I made about 750-800 on just a thin drop in dry replacement sleeves... eventually a hairline crack occurred after about a season of racing.

 

Interesting...

 

I made 831hp on darton sleeve before at 33psi and this year will be using darton sleeve again

 

Closed deck block zakura ?

 

i've got the dry sleeves punched out to 90mm. No problems here (all motor tho)

 

Open deck h22a4 block of a 99 prelude That is what I will be using this year. And when I made the 831hp it was a h22a4 from a 97 SH modified to work with h2b both block open deck.

 

Why are the Darton sleeves your only option? Budget?

 

John If you want a sleeved block, dont half step. I know of another one available with Darton MIDs in it at 87mm currently, but its had a rod go through the front... But then again, I am known to weld those holes shut on sleeved blocks and beat them even harder after its happened ;O)

Its also a JDM block IIRC

 

Rogers Prelude is done this way...

 

Dry flanged sleeves or just cheaper dry sleeve? Didn't know you could punch those out that much even NA

I never heard much of the cheaper Dry sleeves for the H and thought I would see who has tested them out....

Not sure yet how big I want to go... or spend... ideally want to drive on street but step it up little over my 473 hp H23v crx...


Snag it up for spare! lol yes welded up hole'd block has done you well! I about **** my pants when I saw it at first....

I'd probably want to use my h23 block. What's a good turbo man PM me... 550-650hp and 650-750 hp 6262?. Haven't decided how big I want to go... (spend) Precision ideally... price in mind... journal...

PM me your new number if you have one I have new number as well need to chit chat...
