I'm looking to resleeve my h23a1 for boost.

I'm having a bit of an issue finding information on aftermarket sleeves. Stock bore is 87mm right? What sleeves and what bore should I upgrade to?

This is for a sunday driver / pleasure vehicle only. I'm planning on running a precision sc-34 @ medium to high boost
 
golden eagle are supposed to be good as are darton (sp?)
dunno much about H series so someone else will be able to help a little more than me
 
well, I'm still looking for information. According to the reference section, my stock cylinder bore is 87mm. I found some very limited info on Dartons website saying there is a 87mm sleeve(which is no increase) with a max bore of 89mm.

Is a 2mm increase worth the money and trouble?

thanks

Does it take a lot of specialized equipment to install new sleeves? I think they need to be "trued" up to make sure everything is aligned properly. Is this best left to the professionals? or can I do it?
