May 2017 COTM **Winner**
"One-off", "originality", and "f-ing killer" are terms that get thrown around...
but this car defines those terms. And although I don't think I've ever personally used it, the word "gnarly" also comes to mind.
Congratulations, Twin_Turbo! I'm proud to announce that your uniquely one-off, killer '87 IROC-Z is TGO's May 2017 Car of the Month.
BTW, i love the seemingly bare metal finish on the supercharger and suspension parts.
Mine is a complete ground up rebuild. Nothing has been left as is. In fact it's an all new car almost and has a new speedo with only a couple miles on it now.
The idea behind this one was to build a semi 80s correct car with a lot of upgrades. That's why it has 80s super rare jongbloed aero 3 pc wheels. An 80s prototype mcfarland intake (only a couple exist. I have the complete test mule) 80s black interior (original was ugly cloth) etc. The supercharged engine had to fit under the stock hood. It took quite a bit of fiddling to get everything crammed in there.
The brakes are j55... 80s
I have a detailed build thread describing most of what has been done.
https://www.thirdgen.org/forums/memb...t-my-87-a.html (Pulling apart my 87 IROC)
Engine is a 355 wuth tfs g1 heads custom pushrods and crane rockers. Custom valve covers. Mcfarland short ram. Custom fuel setup using mostly aeromotive parts. Ati damper. Modified hedman headers. Custom built serpentine drive with home made brackets. Custom p600b mounting.
Runs on modified code 33 with intercooler pump control has backup control via hobbs switch.
a lot of stuff was modified or hand built. Custom stuff includes the exhaust, subframe connectors, engine intercooling etc.
recently had a full down to metal repaint using only spies hecker for quality and durability.
