FAQ: D15 OBD1 SOHC VTEC Mini-Me : Massive Write-up (56k No Way)

I dont think so, there are a few people here that reused there gasket as long as its not damaged. Its safer if its a metal gasket.

A few notes that I found different from yours, and pretty sure u ya ran into it somewhere else on here.
The head-bolts if u decide to reuse em on the z6 head, the two top-corner bolts may be a tad too long or difficult to screw in finger tight on a B7/z6 combo,
xooox
ooooo
with that said, wat bolts do i need for these two, dont like using washers

Second, my B7 dizzy fit like nothing on my z6, didnt have to mod anything..any info on that??
again nice write-up

B7 dizzy is incompatible...you need the Z6 dizzy...

About the head bolts...thats weird...they are the same length and are the same part # for B7 AND Z6... 90005-PM3-003 BOLT-WASHER (10X140) (SAGA)

[EvilPinkEye]

how is it incompatible....craps up the firing order, timing cant be set right, or worse...no spark?? I didnt have to cut anything, went in like a z6 dizzy, ill take it u tried it, there must be a certain years or sum'n that go together.. eheheh
for that head bolt thing, read somewhere else where they found the same problem in the same two spots.
cant be just me.

I want to order them, but i can't find the description of the Spark Plugs.

Hope you can help me.

[NONVTECSI]

Nice Write Up!!!

[mgutt]

bump.

please help me.

regards

[BauleyCivic]

Just use EX...(ZFR6J-11) (NGK)

[mgutt]

Perfect! Thank you.

Well I just decided what I am going to do when I get my car now. I have a few questions that will be easy to answer but show my lack of d series knowledge. First off I plan to do this in a 88 - 92 civic and I am wondering if any of them come with a bottom end that will not work? If so what models have this bottom end so I can avoid them. My other question is am I still going to use a P28 ECU described in this write up for a non OBD I car and do the same wiring as described? It seems like a really straight forward swap and this write up is excellent. Thanks in advance for your help…

Has anyone done a before and after dyno for their mini-me? Just curious about how much of a gain this would give me.

Bump - someone must have an answer to my questions.

theres no d-series from those years (88-91) that wont work, unless its a DOHC like the d16a1 or a ZC, which DONT COME STOCK on ef's, so:

if the car hasnt been swapped before, you can do this. If you use a 1.6 si logically youll have more power potential in the long run, and more closely emulate the d16z6

personally i think its not that much more money to save up for something like an LS, but ingenuity of any sort is cool, and vtec doesnt hurt... and who doesnt love that little midget?

hey for the water pump, will a z6 waterpump fit on the b7 block? also the same goes with the tensioner and spring( z6 on a b7)????

[jsw_1986]

I have to say that this was a great writeup, looking forward to doing this swap in a couple weeks. also had a question. I use the p28 ecu for a d15 block and a y8 head right?

[88crxCF]

nice write up. im gonna be doing this to my 88 crx and hopefully ill be able to be running high 14s or low 15s.my tranny has really long gears though so it sucks.but ill get a better one soon.im gonna use this minime till i get my b16 with turbo.

[joboost13]

great write up Was gonna do my mini me soon, but i was going 2 use a y8 head. I have the complete head and i already converted it 2 obd-1, do i use the y8 water pump and timing belt on the b7 block? Or do i use the zc ones, cause i thought that the cam gear was diff 4 both, y8 has more teeth on the belt. Any one have any info on this?

[joboost13]

i got my jdm 1.5 vtec head 2 day, and i was wondering if i can use the z6 dizzy? I also have a y8 timing belt brand new. Will this work wit the jdm head on the b7 block?

[shakenbake]
