Mini me Users --> Was it worth it??

[dssmax]

Hey,
I just got a quick question for people that did a mini me,
Was it worth it?

I meen, I did a DPFI to MPFI and if you asked me if it was worth it I would tell you "Hell Ya" there was no way that by me just adding a few bolt ons that I would get the same gains and over all feel of power that I got with the MPFI conversion.

So I ask you all users of Mini Me's was it worth it or would you have invested your time and money in to another comparable mod for you car.

Oh yea this only applys to the folks running OBDO...




THANKX,
MAX

not worth the time/effort/$$

its not as cheap as you think.

[91civicDXdude]

definately worth it. If you car is already MPFI, it *might* cost $300, including your VTEC activation method. I happened to find a z6 head for $75, bought valve seals for around $20, had it milled and cleaned for $40, and had a brand new head for around $150 bucks. compare that to buying a header for $300 or some other crappy ass mod that will give you 3hp.

Plus you get the added benefit of smaller combustion chambers, which raise compression, larger valves which flow more air, and the added benefit of VTEC which really shines in aftermarket cam(s). I have one of the biggest cams made for the d series engine, yet it still idles like stock. try to idle a d16a6 with a cam that has similar specs as even a stage 1 VTEC cam and you will find you have to raise the idle to over 1,000 rpm just to keep it running.

no, VTEC isnt a magical force that instantly makes your car have 400hp, but it is a useful feature.

not worth it. i'm becoming thumbs down on mixing in the a6 parts as well.

i have had the y8 a couple of years now. i have been running p28 ecu, dizzy, intake mani + rpm activated switch. this is the problem we have found...the a6 injectors are slightly different from the y8 which is slightly different than the z6. they all have a shape. the a6 injector doesn't seat all the way in causing gas to collect which = clogged intake mani. 1 & 2nd gear sputter due to gas flow problem SUCKS.

i suppose if you don't mind taking the intake mani off every 6 mos or so to clean it out, you'll be cool. right now my stuff is clogged again and i'm pretty sick of it. since i already have the rpm switch i think we're going to put the y8 intake mani & injectors back on and try an ecu out of the MPFI obd1 5th gen. i can't remember the ecu # but you get the point. we'll let you know whatever happens when we get around to trying it....lol

yeah the mini me is aight... but its nothing too great... hell my a6 with a cam felt much better...and this 20 mpg shit sucks!

a friend of mine mixed a d15b7 block with a y8 head, was nothing but problems. For some reason (maybe head and block combination) and he ended up with a really high compression ration, which gave him lots of problems (as his daily driver), he had to run 93 octane gas, get an upgraded started to start it (his old one might have been old) and it still didn't run that great (he was also using a a6 mannifold with a vtec switch), anyways save some agrivation and buy the complete engine if you want to go vtec, in the long run you will be more happy I would think...

Just get a complete sohc v-tec swap.

your using the stock PM6 not p28 ami the p28 is the obd1 ecu you would need to get

I don't know if my friend used a different head gasket (or wrong one) or I am getting the block code one, but he claimed (I am not sure how he calculated it) he had 11:1, and he did have to run it off 93 to avoid detonation (not desirable, since not all gas stations carry that high a grade)..

sorry typo. it's been a loooong day

i still stick by the story that the mini-me is a very versatile engine and has many benefits.

Im running a Y7 block with a Z6 head with my turbo setup. since the Y7 has a slightly bigger dish than the Z6, it actually has a little bit lower compression, which could very well be why this engine has held out so long with boost. 10psi every day for atleast 6 months, and if you know me, you know that i beat on my engines.

as far as fuel puddling problems, i've never had any, heard of any, or seen any.

As far as the A6 mini-me goes.. a friend of mine has an 88 CRX HF with an A6/Z6 mini, comp 59300 cam, DC 4-2-1 header and some generic short ram with a PG7 ECU.. his car will most definately run mid-low 14s.. he has only ran it at the 1/8 mile and ran a 9.4@77mph with a 2.2 60'. higher compression with the a6 pistons and the comp cam make it a monster.

I have had nothing but good experience out of mini-me setups.

Thanks alot for the info, I did alot of searching and reading but sometimes its always best to ask.

I guess because of my block (1500 cc) it won't run right, best bet to get another motor and work on that, to bad my civic has only 64,000 orginal miles on it and was owned by an aunt who never abused the car.... ( I guess its up to me to do that... )

Well, I should be happy with what I've got, that damm MPFI blew me away with the diffrence that it made.. Also to any body that did a MPFI and did not notice a real change you must have did something wrong, probly timing or intake leak or something.


Thankx,
MAX

I'm still debating going with a high pro cam or a Mini me. I have a D16A6, and I need to get a cam anyway... I guess I'm just torn by all the pro's and cons of both options. can anyone tip the balance?

[dssmax]

Hey Jehu,
You and I are in the same boat, I swear this is killing me..

From what I have gathered you get a few ponys with the swap, the thing is when you go with a bigger cam and vtec you can still idle pretty well...

I just like the fact that you can tweak a vtec setup to the way you like it, by controling when it switchs....

Hrmmm.... Now that I think about it I could use a Apexi VTEC AFC II to control the air/fuel as well as the vtec and even though I would have 10:1 compression I could control any pinging that I hear people have when using a D16 head on a D15 block..

ARGHhhh!!!!!!!!!

What to do, I have no clue... lol lol
Sh!t.....
