Hey there I got my z6 for $120


umm I know why it was $120 :pinch:


I am in the process of tearing it down however it will be a "stock+" rebuild. Don't tell my mom that :sweatdrop: the extra money I'll be spending will be our secret.


The build for my head is as follows:
-Cleaned
-Valve Job
-ARP Headstuds
-Stage 1 Bisimoto cam w/ stock springs
-($ permitting) 3-angle valve job
-($ permitting) Port polishing

For the block I am doing:
-Stock rebuild kit from FJ Distributors
-Block cleaned and bored to 75.5mm
-Rods cleaned and checked to be in spec
-Crank cleaned, polished, and checked to be in spec
-PG6 Pistons
-ARP rod bolts

That should give me that little extra oomph over any other bolt-on build and be solid. Also when people ask me what I got under the hood I can say, "aw, nothing just a Z6." Everything should fit together well and I won't need to run a tunable ECU. Obviously if there is anything grossly wrong or unnecessary let me know.

It is going into a 1991 Civic Hatchback. It has a ZC transmission, front and rear sway bars from an Si, and front and rear brakes from an Integra. :)

Looks good so far, but just so your aware the pg6 pistons put you well out of "stock ecu" range. You will need to chip and tune for that combo. And if your going that far you'll need a bigger cam to go with the higher compression. Unless you mean pm6 pistons which would be more ecu friendly but still better with a tune. Just some food for thought

I must have gotten things mixed up. I thought the pg6's only bumped compression by about 1 point. That is outside the stock ECU's range? Hmm... I haven't bought anything yet so I will start searching some more.

The hardest part about the rear disk swap was the emergency brake cables.

Use the Pg6 pistons if you can find them, then order a chipped PM6 from Xenocron with a decent TurboEdit basemap on it. Don't be afraid to tune it or have it tuned. It will be more efficient and faster in the end. Also if you do bump the compression with the pg6's I'd also consider running the Bisimoto level 2 cam if it's the same price. It's still going to idle like stock, but you'll see a lot of difference in performance, plus the bigger cam will bleed off compression at idle. You should still get 30+ mpg as well.

You need e-brake cables from a 90-93 Integra, in fact the rear disc setup from one of those cars will fit completely. I have this setup on mine.

Stock z6 is 9.3:1 with pg6 pistons it's 12:1. Def would need to tune an use a bigger cam to take advantage of the comp. If your not looking to dig that much into it I'd suggest some pm6 pistons(usdm d16a6) pistons and mill the head .020 that would put you at 10.5:1 or so which would be the limits of the stock ecu

Running the cables and bolting them up was the hardest part. The exhaust is in the way.

I need a crankshaft and I am having a hell of a time trying to find one, short of getting one from the local junkyard. I don't feel like dropping a tranny and pulling the flywheel and all the other work involved to get the crank out while it is cold and wet here.
