I started this in december but due to the massive amount of snow and the rain every time I was free from work im now finally getting back to the Z. I figure I'll follow the trend and make a progress thread.
At this point im working on the Z's current engine's overhaul. This engine will eventually go into the vert when I put the built engine in the Z, hopefully by the end of summer. But for the time being I need the Z to run. The list of goodies for this engine are as follows...
-Stock 01 bottom end
-ported and polished 96-98 head w/ SS valves
-87-88 2.3 cams
Specs...Intake lift .340 w/ duration 210 at .50 Exhaust lift .350 w/ 210 duration at .50
-87-88 intake tubular intake manifold with phenolic spacer and custom spacer to enlarge the plenum to up the power range some
-bill and stan's 4-2-1 header I got for 30 dollars
Im going for the peppy feeling with good midrange power for a daily driver
Before pic
How she's been sitting for a while
Today's project is cutting the old downpipe off and cutting the water pump in half since the bolt heads decided to round off. I needed a new water pump anyways. then taking the 086 off and bolting on the 2.4 head.
More pics to come soon.
good start.
Sig thanks to bxmobkrazey on gmscf.com
Thanks, I cant wait to get the car on the road again.
awesome.
love the old school towers.
All I want... is a little of the good life
Thanks! I had them and the old school cams under my bed for about 5 years and never knew what I had. I always thought they were just LO cams that I bought for the housings for an HO swap.
I got some more accomplished today...one more full day of work and it will be runng for sure.
And the header
Nice man, I wish you dynoed before this swap, to compare to this new setup.
I was gonna use my smooth old school 2.3 towers but I didnt like the fact the top halfs didn't have the grooves for the gasket.

I wish I got to the dyno when the 086 was on too, it would have been nice to compair and to know how much power difference there is in that headswap. Im not sure how I feel about the cam tower grooves but this is only an experimental engine anyways. If all works out as planned I will put this engine into the vert when the Z's REAL engine is put in. I will probably change out the cam towers and switch to the 2.4 style powersteering when I do that. I do like the oldschool look of them though.
did you go 'wtf?' when you saw the steel lifter bore inserts in those towers? LOL

haha they did look different but i remebered reading about them on a post a while back.
I remember seeing an older thread by Mastin I think, He dynoed the different intakes and posted a loss with that one N/A IIRC.
Looking good though, Get numbers!!
I remember he said the HO intake lost power, i wasnt aware he did this one too. Its an experiment so im crossing my fingers. In theory it should promote midrange torque due to the long runners, which works with my cams and header. The problem is it supposedly doesnt make any power after 5600 rpm. For the moment I just bolted the throttlebody on but I do plan on adding a large spacer behind the throttlebody to elongate the plenum and hopefully bump up the rpm range.
Im not sure I will dyno this engine but it will definitely see the track for some 1/4 mile times.

Maybe it was the HO and he didn't do one of these.....Either way, I think that intake looks the best
Updates....
Today I finished tightening the timing cover bolts, attached the header, and installed the motor mounts. The engine sits on its own wieght for the first time since december.
Next step is install pulley and belt, lower motor mount, upper radiator hose clamp, fuel pressur regulator vacuum tubing, weld te exhaust, install intake and filter and fill the radiator. Car should move under its own power friday.
Project frankenmotor is almost complete.

I was part of those test, we ran the stock manifold compared to the HO manifold.
Anyway GET A MOVE ON!!!!
I wanna see this done

I think bigfoot is blurry,
that's the problem. It's not the photographer's fault. Bigfoot is blurry. And that's extra
scary to me. There's a large, out-of-focus monster, roaming the countryside.

Hahaha i had a long period where I lacked motivation but now im so close it will be done soon
I wish I didnt work a double tomorrow or itd be done then.
It runs sort of....it sounds like crap because of the open header and trashed header gasket. For some reason the fans wont kick on and its overheating. im gessing its an airpocket. how do I get rid of that...
Thanks
I cant wait to see how it performs.
On a side note there is no cam sensor attached and I have no CEL which confuses me.

I took the car out today for its first run. It ran great until the power steering pulley ate through a plug wire. It definitely has the torquey feel...you dont really feel like your moving but the speedo is hauling ass.
As for the intake manifold the power does not feel like it drops off until about 6000 rpm.
Once I get the exhaust welded on and the plug wire fixed I think I will love this setup for a DD.
Sweet news man. Keep us posted.
i will for sure! I'm hoping to get the exhaust done this week.
Exhaust is done with the exception of the leaky header gasket. Runs strong, i'll post a vid of it accelerating soon. Im still working the ignition timing, it jumps to 6 KR after 5000 rpm. Ive only pulled it that high a few times to see if I retarded the ignition enough.
For the neigh sayers the tubular intake doesnt drop off from power making until about 6100 rpm....I did use a phenolic spacer so maybe that added a few hundred rpm.
Should be quite a nice daily driver engine.
