I was just wondering if it is possable to put a vtec head(d16z6) on a 1995 cx block? I have a stock cx motor in my hatch right and i just wanted to add alittle more horsepower to it, And i heard this is one of the cheapest ways to do it. thanks in advance!

I heard its like the the ls/vtec conversion...GOOD LUCK...its been done so dont lose hope

 

but you mite need a 1.6 block not a 1.5

 

I don't know off the top of my head... is the difference between the 1.5s and the 1.6s bore or stroke? If it's stroke, then everything is fine with the mini me. CX pistons have 4 valve reliefs. If it is bore, then you need to watch clearances to avoid slap.

 

thanks!

 

A little more hard facts and a little less hearsay/post whoring would be nice.

As with most 1.5/1.6 sohc it's the stroke that is different.

That is a VERY indepth and on going thread on mini-me's. Not to detract from H-A traffic but I couldn't find a mini-me write up at quick glance.

 

So you just swapping the head now Flappy?

One other thing you should keep in mind is that the CX tranny is a steaming pile of crap. Keep an EX tranny in mind for down the road... it'll make a huge difference.

 

I personally would ditch that CX trans before the head.

Then again, I'd just go for a D16Z6 swap. They're pretty cheap these days.

 

Ok now, YES you can make a Mini-me setup with a CX bottem end. The great thing about the CX bottem end compared to the old HF CRX bottem end is that the CX comes with 16 valve dished pistons, instead of the much smaller 8 valve pistons from the HF. You must use a 92-95 VX timing belt, 92 si/ex head gasket, remove the oil control Jet, and use a 92dx or 92si/ex intake manifold with the Z6 FPR (fuel pressure regualtor), and highly reccomend using a Si/EX harmonic balancer(Crank pulley) to save the life of your Main and rod bearings. Then you have to find a suitable ECU, of course with a 92+ you have the great pleasure of being able to use a P28, which is nice. But for a car like mine('91 CRXsi) I had to use a PWO ECu from a B16 because I didnt want to wire up a cheap ghetto RPM switch. Then I had to re-route the 2nd O2 sensor and wire up some VTEC, its all good fun though. I built my motor just right too, almost perfect actually, it has a great power band which lets me rev safely to 8000 RPMS!!! and also, have you ever actually heard a single cam HIT VTEC? Mine hits it nice and hard, It makes me mad though because I invested in a B16 3 months ago and It'll be here on a container ship in a week. But guess what, Im getting the same amount of torque to the wheels as a B16a would, and my single cam is so much lighter that the power getting to the wheels almost comes out to equal a B16 powered CRX. But in the end, I know I'll be more satisfied with the B16a.
Sorry for the book I wrote, but if anyone needs any tips or anything on Mini-me's n such, hit me up on AIM or something...
