At least, this is what I hear.

As for the Type R head, why not get a Type R block too? Better (lighter) conrods and higher compression.

Alternativly, as has been mentioned, get the Type R plenum, New lumpy cams, new valve springs, port and polish (carefull who you go to), extractors and exhaust. You might also want a lightened flywheel (I know my integras flywheel is as heavy as an Elephant with a penchant for junk food) clutch and suspension work.

My take is an atmo 1.8ltr is never gonna make massive numbers. I'd focus on suspension first, if you haven't already. My Integra handles like a monster even on stock suspension. Put coilovers, new sway bars, tower strut braces and a Type R LSD in the front and not much is gonna be able to out corner you.

Vtec hondas can take boost as long as its tuned well.
And as for a stock dc2 handling like a monster, you obviously havnt driven a dc2r hard.

It can take a little, but I'd want stronger rods before putting any decent boost down.

Heh heh. Yeah I figure the Type R must be freekin' awesome if my car can do what it can. I'm actualy rather shocked that the rolly arse suspension in the VTiR does so well against S14s + coilovers, R32 GTRs + coilovers, Modified ST185 GT-Fours + coilovers, JZA70 Supras (although with kinda average suspension and LSD), MA61 Supras etc.
