Back on topic:

Not being able to affordably sleeve a Honda 1.5L block is what stopped me from doing what you were asking about. That... and Eagle makes 1.5L rods, but they don't make a crank for a 1.5L. Who does? I don't know the limits of a 1.5L crank, and with the rest of the cost of machining, I don't know if it's worth it with the stock crank.

If you really wanted to boost it, at least put a head that flows better on there, like the B7 head. You can still put the sleeper 8-valve valve cover back on it because the 1.5L valve covers are unique to the 1.5L engines. The valve cover from a DX or Del Sol has "16 Valve" cast into it. The B8's are the plain crusty black ones.

You can use the B8's exhaust manifold to hack a turbo flange onto for whatever turbo you want to use, www.machv.com sells blank flanges for various BOV's Turbo exhaust housings, Exhaust flanges, etc... Most machine shops can either weld on the flange, or make a bolt-on adapter plate without too much trouble. A lot of people go this route if they don't want to buy a manifold or a turbo kit.

Use a set of 450cc DSM injectors. Used. So many turbo DSMs came with these. They're always being sold, most likely by someone in your neighborhood. Re-plumb your fuel system, get a Walbro in-tank fuel pump, get an aftermarket filter and regulator, set FP at 37 or 38 PSI. Tune your A/F ratio with an Apex'i S-AFC.

You'll need to replace your exhaust. You can get your BOV mounted on the intercooler end tank and hide it inside the fender so your upper intercooler pipe looks like a AEM cold air intake. Use a 2g DSM side-mount IC, and cut the plastic fog light hole out of your bumper. Nobody will know you're boosted if you can find a quiet enough BOV, and if you can make a heat shield that hides the turbo.

There. That's what I've always wanted to do to mine. 'Sorry 'bout the thread-jack. 'hope some of the Honda stuff mentioned was helpful.
