After snapping my timing belt on my old d16a6 engine, I decided not to repair the 12 valves that were bent. I considered the ZC engine, but the parts availability for the engine made me reconsider. I recently contacted a buddy of mine, and it turns out he has a brand new SOHC Vtec head, already milled and for about $200. Im really amazed on the high compression ratio, parts availability, and VTEC due to the mini me setup. Ive heard a lot of great things with this kind of setup, but im worried that my block might not be able to hold due to its high mileage (160,000 miles). Im still considering a ZC, but I wanna know what you guys think i should do, which would be faster? which would be cheaper? where can i get this stuff done?? any feedback would help, THANKS.

 

mini-me is faster. mini-me is cheaper. u can get it done in your garage

 

OK, so say i get the head, now what do i need to do the job? tools? instructions? or should i just pay a performance shop to pop the head and vtec parts on?

OPPS, this is my brothers member name.. im SiRJkwick89ef

here is the HOWTO that i used http://crx.honda-perf.org/articles/z6swap/z6swap.html Just follow that and it'll work dont forget to take that oil jet out, i did it by screwing a little screw inside of it and then pulling it up straight by the screw's head w/ pliers. as for parts u just need 92-95 t-belt, any new head gasket will do it doesnt matter if it's 88-91 or 92-96, u will need to turn your distributor toward the firewall a lot more than stock so u'll have to do something like this guys did
but not necessarily THAT far. for example mine works best about 1-2deg to the right of his. other parts, like dist caps and rotor, head bolts and etc are nice but if u really wanna save money u can do w/o them.

i would recommend u replace thoe rings cause tehy WILL start to smoke soon afte ru do teh vtec head thing, u are gonne be streessing them a lot more withteh higher cylindr compression that the vtec head creates due to its dome desgn and also that your head is shaved will put even more strain , also make sure yuor valves wont hit the pistons, u deffinatly dont want that and umm yeah good luck

 

how much quicker are you guys with minime swaps running over your stock setup? 1/4mile times? what can you guys compare to?

 

A friend of mine just dropped a whole SOHC vtec into his 88 CRX, and it pulls a lot harder than i thought i would. I would definatly do the mini-me over the ZC, just because of parts availability.

 

aparently no one goes to the track, so no one here knows their 1/4 mi times. and it seems like no one does the mini-me swaps either. hmm, i dunno what to say... mine has been running w/o VTEC for about 2 months now and i'll connect the rmp switch up after i change oil sometime this week. then i'll have to go to a track and it seems like the closes one is in North Carolina about 1.5 hours away. then i'll definetely post MY times. i still dont understand why people dont do mini-me's or why they dont take anything to the track...

 

I think I would go with the ZC. I have never heard any power figures for the mini-me swap. what's this about parts availability for the ZC? stock or aftermarket? I would still do the ZC, unless you really want VTEC. then I would do the whole SOHC VTEC motor swap.

 

if u swap the whole SOHC VTEC motor in a crx u get less tq and less hp than w/ a minime

 

OK, OK. but I would still like to see some hp and tq figures.

 

well.. at least give some kills youve had with that setup..

 

no kills yet cuz i thought i'd be pointless to try w/o VTEC hooked up. and i also had to break the new piston rings in for a while. and im driving on a worn clutch that slips more than i dunno what...

 

its hard to say...but at N7 a friend had a ZC and he beat my other friend who did the Z6 swap, but the mini-me is a little different since you would get a little bit higher compression, but the est. hp on the mini-me is about 127 with the Z6(125hp stock) with the Y8 129-130 (127hp stock).

 

stock d16z6 motor in 92-95 civics is 127hp and expected hp of minime is well over 130hp

 

Given the options I would go ZC I had a couple of ZC's and they proved good power. VTEC is a gift from the gods though. I had alot of fun at N7 with my last ZC lots of people thought I had more than just a ZC. I've gotten so much more out of my newly swapped b-16 though. After all considerations, after all the swaps I've done, nothing is nicer than a good b-series. With the ZC supply drying up prices have gone up and it really isn't too much more now. If you are stuck on ZC or mini-me, I say ZC.

 

nah man, the Z6 is 125hp stock the y8 had better breathing that is why it was 127hp stock...im sure that it didnt raise the compression that much were it would increase it over 5 hp...but then i could be wrong about the compression being a lot higher...but the i am correct on the HP figures.

 

the cylinder pressure went from 156 to 210 i donno if thats hihg enouf for u, but thats equvalent to ~10.7 compression

 

I just got through doing the Z6 head swap a few weeks ago. The main reason why they say it does not run as well as a ZC, is not switching to the proper ECU (P28). You do not get the mapping from the Si ECU to take advantage VTEC fuel and timming, that goes along with it. The peeps that have done the switch say there is major improvement after doing so. I have not done that either... yet, but soon will be.

Here is a page I did with most of the parts you will need:

hey would that ecu be better than a stock ecu in 89si

 

I have a buddy with a 1993 civic cx HB that ran 9.8 in the 1/8 with the D16 SOHC VTEC motor, Full interior... It had a light flywheel in it though.. 3rd is really tall with stock gearing though, it would hit a 100 in 3rd, so 1/4 mile is probably slower.. like a 15.5

 

ok i'll chime in here. that pic of the dist is my mini me! lol thanks max! well i haven't taken it to the track yet but i'm planning to soon. i replaced my rings at the same time of the swap, so yes it is a good thing. but i didn't do my bearings my car has 180,000 on it and i really should have done them. well i was planning a b16 swap for next year but i've decided to stay w/ my mini me. i'm gonna rebuild it next spring. higher comp for some NOS. well last year i can tell you the car ran 15.9 at the track. that's w/ no act clutch, no mini me. basicly dc headers, cat, catback exhaust, weapon R intake and short shift.

 

hrmm kills w/ my mini me..... 87 crx si (no challenge), 88 Toyota supra turbo (smoked kid complained of new turbo on it's way) 00 ex w/ intake automatic (no challenge once in second, 97 nissan 240sx se 155hp stock 150torque intake n1 dual catback (1 car length ahead at 60)

 

by the way i run atleast 93 octane gas to get rid of the ping. i'm installing oil pressure gauge and air/fuel gauge next week. by the way i set my fields vtec controller to 5200 rpms for vtec activation and i can now definately fell and hear it gives you that extra boost near the end of the stock powerband.

 

Hey 240, i really like your setup, thats sorta how i would want mine to come out. All those with Mini-me conversions.. are you guys really satisfied with the outcome, like how quick, and how smooth does the engine run? Im in the process of removing my head, and its a real pain in the ****, any help with that? Ok, as of now Im in the process or obtaining a brand new Y8 head, thats milled and i think has mild head work. I also got my eye on a p28 ecu, what else do you guys recommend? I need in depth instructions, anyone know where i can get any? hey Nismo240.. how do you like that setup? your car looks almost identical to mine, clean.
