have a 92 civic cx woth a stock 70 horses ive added a dc header a full apexi n1 exahust and an intake but still dont have the power i want, the motor only has 98000 miles on it so i dont want to do a motor swap but im looking into a d16y8 head swap ive heard good and bad things about them anyone know anything ...ive heard they have a tendency to overheat .... any other suggestions for noticable hp gains without a swap any info will help!!!

Jarz GTI

i think the gain with that swap as long as its 16v.. is like 40hp or so.. but it would be well worth it.. instead of ur little *** cx intake and injectors.. youd prolly have to swap the ecu also..then you would have to hook up the vtec unless u get an ecu from a vtec and hook it up.. from a 92 dx vtec 1.5 would prolly work.. just got get the bigger intake mani too!

I would definatly go with the head and intake swap... probably get a real good gain.

could i just use the injectors from the y8 head >>>

would i have to swap out the pistons too because the cx is only an 8 valve ant the new head would have 16 valves i dont know much about the piston reliefs

leave the bottom end and just swap out the entire top end. get a compete Vtec top end and and bolt it on. along with a 92-95 civic ex/si ecu

what size are the y8 injectors anyone know>>>>

also if i went with the y8 injectors and manifold would that increacs horsepower if so how much more than the stock cx injectors and throttlebody?

i dont know the size of the injectors of the y8, and i wouldnt advise just using the injectors. you would be much more happy power wise switching the whole head. like its said above, youll get 40 some horses. 70+40=110. youll totally feel the differnce.

I agree, just get a y8 head and intake manifold with all the ---- on it and put it on your stock block. you could easily see a 35-45hp gain.

Your engine is a 8 valve, but... read this thread..

I think you will be just fine..

Get the correct ECU as well. The Z6 head/intake is also an option.

The y8/z6/a6 injectors flow at 240cc

i went to my mechanic today and he told me that for about
$1300.00 i could have a y8 head apexi v-afc vtec ecu
and my head "CHIPPED OUT" (im not 100% sure what this means but he said it would increase my fuel curve, increase my redline and give me 15-20 extra horsepower) all installed

any other info you could give would be great

anyone heard anything about mini-me's overheating

HMT-Admin

Your mechanic doesnt know what he is talking about, you could easily get a gain of 40hp with a stock p28 ecu. Even more if dyno tuned with a VAFC.

look at it this way..

D16y8 & D16z6 are rated at 127hp (STOCK)

Mini-me 1.5's are normally around 120-125hp (due to the high compression)

So from your stock D15b6 that is pushing 70hp right now, its going to be a huge increase.

1300 bucks? ouch, thats a bit expenisve, you could shop around and piece this all together yourself, and install it yourself for less than 400 bucks easy.

Overeheating? Nope.. not a problem at all. Just be sure to remove the oil oriface jet on the face of the block, and use a d16z6 head gasket.
