Okay - I am in the same boat here and I’m glad you posted . A while back I had a misfire issue that was very hard to diagnose . It was the spark plug wires were leaking and cross firing . These were genuine GM wires that weren’t very old . It took forever to figure out . Put a new set Magnacore on there and fixed it Now I have put a bigger motor in and have a high compression build I am having issues again. #6 is fouling for no apparent reason . I swapped everything possible , coils, wires, plugs, injectors - nothing helps . 225 cylinder pressure , good leak down test, good coolant pressure test . Getting ready to install a zx dizzy and wires to check to see how things go . I think these smart coils trigger to easy . #6 coil sits right above my starter . Maybe proximity is going to be the issue . If not I have a hardware problem - like piston ring ?

Is this group buy still active ? I’m ready to pull the trigger .

P79 sold

I have a clean p79 from a fresh part out . Deck surface is flat , and valve train looks good. All the spark plugs had nice burn to them . Should be able to bolt in and go -250$ E-88 is late model with OEM valves . Looks completely stock with a good cam and rockers . Deck surface is .002 out of flat - probably be fine. 99% compete , but missing some mouse traps . Just a great core with most pieces including spray bar - 150$ shipping extra

L2.4 is gone and the L 2.8 is in. Time to challenge my tuning abilities .

Well I let this thread slip along with the build. Anyhow, it’s running with a Don Potter cam 11.25:1 CR A little vid of me driving around breaking it in.

Still have ECU, injectors , AFM,

Getting ready to install next week

Hard to imagine that’s Pertronix out performed LS2 coils

The gas smell drove me to EFI also. It worked well for me to shut the fuel off a couple of blocks from the house and empty the float bowls that way, but EFI is a better solution. Love those Jenveys

Looking great

It looks like you have all the ingredients to whip up some good power . I’d see what a 3” down pipe could do for you . It might change more parameters than you think. Do you run a knock sensor or did they have one at the dyno?

No experience with turbo builds , but from lots of reading here it seems that the very first things the guys do is the down pipe increase. You have invested a lot of money in forged pistons and other goodies , but you are choking all your investments with a tiny exhaust. Timing might also be a victim of your small exhaust. Don’t want to build heat by bottle necking flow. What was your timing at?What was your AFR’s?

P90 had steel seats already. Only heads that had brass were very early heads

Distributor is sold . Taking offers on remaining pieces.

Just installed mine . Numbers are good - especially P2V clearance for a 535 lift cam

Spindle is sold

I’ll try and have a pic by Sunday

It’s the complete car harness so it’s in a milk crate filled to the top

I’d do a package deal for the right price . Would be great to extras of everything !

I would separate since I have two of you right here- lol Selling these for a friend that is needing tires for his Z . Trying to be fair on price . I would think 75$ on the spindle and that make sure the dizzy 175$ ?

It’s a quick fix sometimes , but not sure it’s worth the shot. Though Hybridz got a bit sticky with its rules , it did tend to keep on topic . I use to post all the time because I was stuck in hotels and thought it was fun to share my projects and learn . Back then I toted a laptop with a real key board . We’ve lost a lot of talent that use to be here often also. Well things seem to come to full circle , so maybe folks that want real knowledge will come back to the forums .

From a 1983 ZXT , manual trans - that had 112k miles and succumb to rust and a bad turbo Dizzy - 150$ obo - SOLD spindle shaft - SOLD AFM- 100$ ECU- 125$ fuel injectors with rail - 100$ complete harness including engine harness -150$ prices are best offer shipping extra

I’m sorry that I even posted this thread- but like I said - my settings were screwed up and so I wasn’t seeing any new content . Glad it’s ALIVE !!

Sweet!
