F1 spec 4-2-1, bni /wrapper, sitting in my basement. i'm going f.i. and don't need it. and to be honest, i'm only asking a bit more than what u paid for the Megan. do you have a light flywheel? it will be one of the best, low cost, high reward parts that u'll install. whats your revlimiter on the motor? if its low (7600rpm +/- 200rpm), i think a port matched p30 and itr t/b would have netted more power down low. non-built b20's (i.e. stock rod bolts, valve pockets, non-vtec water pump etc.) should not be revved high, obviously. and i'm pretty sure that you'll probably net better low speed power with the smaller intake plenum, lower rev-limit. actually, u'll probably generate the same peak power, (faster cylinder filling) earlier in the powerband with the p30 vs. p73. anyway, pm me if you want the header

and, 187whp & 146wtq are good numbers, eh. don't get fooled. thats good wtq for a relatively low compression motor with little to no mods. just out of curiosity, why did you run titanium retainers and oversized valves? and, is the j's intake, the whale ****? if so, those things heat soak really quick on the dyno.
