hey folks d15b2 block + d16z6 or d15b vtec head + z6 or y8 intake + mpfi + crx si trans + obd2 + ex ecu. can this be done? i recently saw a civic posted in craigslist which i found quite interesting. it was an EF hatch with with a rebuilt d15b2 block + d16a6 head(crx si) + y8 intake manifold + multi + "no fuel cut" + crx si ecu + crx si trans. had the usuals such as header, exaust, coilovers, and an aem intake, and even an autometer a/f gauge. maybe some more details... yes also it had headwork done, the exact numbers went unspecified though. this really turned me on, and made me curious about the b2 block. ive seen ppl in europe swap in b2's in thier EG's, and of course we've all seen plenty of EF dx's with I/H/E ..so im curious if the older b2 blocks are actually stronger and better than the d15b7 that was used in the EG's. maybe the bore/stroke is more desirable too, idk. fresh b2 blocks arent that expensive, and if you take care of them and dont abuse them theyll actually last a while, ive seen plenty of dx EG's still on the road and some that have been babied are going for around $2000 so im thinking this would be a perfect hax for a nice moderatly powerful but satisfying DD. it wont outrun DSMs, but it would be fun to drive, and rewarding i believe, if the stock b2 block is strong enough for an engine rating of 88-100 kw, under nominal conditions. 88 would be sweet and great fun for little comprimise(assuming these b2 block are strong). 100 would be just plain nasty and would = the stock power of a 4age smallport... which is more than enough for an EF hatch. this is for an engine that is to be built strictly N/A and no nitrous, since its going to have to last, and keep high compression. im not interested in turbo or supercharging, i prefer a nice highly responsive n/a engine. a lightwieght flywheel would be nice for this, but i wouldnt want to make the comprimise for a DD, for obvious reasons. high compression is perhaps one of my biggest concerns. its rumored that the a6 head is the same as the b2 head, but that the z6 or d15b vtec heads will be cutting it close.. here are a couple examples of the possible combinations in question: compression raised ratio or lowered? d15b2 + a6 head d15b2 + vtec z6 or y8 or d15b head does anyone know the results? i used to have a d15b8 in a cx hatch, which means roller coaster like driving, using hills, interia and manipulating the effects of gforces upon the vehicle to make up for the lack of power. floating the vehicle like water through a aquaduct is the closest i can come to explaining it. it DID have power sometimes though, just enough in certain spots, but nothing for ecceleration, or hills. i always thought of fitting an ex trans to the b8 block, but then i sold the hatch and bought a corolla gt-s. im about to get back in the game again, looking for a civic as a DD so that i can either rebuild or swap my gt-s engine. so, ive decided that in the event im lucky enough to land a clean EF hatch(no sedans), i would like to do d15b2 + d16z6 or d15b vtec head + intake + mpfi + crx si trans + obd2 + ex ecu. and actually, id settle for the crx si swap like the guy in craigslist. but im much more interested in doing the vtec head. its either that or end up with an EG already vtec swapped. i would much more prefer to do the Ef hatch build. to me, and even with just the dx trans, this seems like a practical and low cost hax that can be done in 8 hrs without the addition of the si trans. its also rumored that the crx si trans has the shortest gearing of all the d trannies... any info on this would be greatly appreciated.
