1974 Datsun 260Z / 2JZGTE "Zupra" (Supra) build (Part 1)
We're back at it again! This time we've decided to take it oldschool. We've owned this car for quite a few years (in different states of tune and with different motors), but we REALLY wanted to do it right with a 2JZ GTE Supra swap.
The focus of this project was to have something that's different, can make good passes down the drag strip, handle the twisty stuff, and has good driveability around town (if ya know what I mean).
We had already done the swap and, and in this latest build, the car was already running with the 2JZGTE as the powerplant, but we weren't satisfied with the "mediocre" performance and output, so it was back to the drawing board!
The 2JZGTE motor and manual transmission were removed to tidy the engine bay (which at the time had been through a lot since 1974) and also to refresh the engine; i.e. seals, gaskets, bearings, rings, and has been strenghthened with ARP hardware throughout.
Out comes the stock, twin turbo unit!!!! Time for some rib-crushin' acceleration that only a single turbo can provide!!
Engine bay minus the engine and a WHOLE LOT of cleanup work to do:
Under the battery tray is NOT a good look at all!!
Opposite side of engine bay showing the brake booster, master cylinder, etc. Pretty, right? Below are photos of what we we up against:
After taking it all out, we realized just how much "fun" this was gonna be. There were a multitude of holes and wires that were left abandoned after the L-series motor vacated the premises. Needless to say there was a lot of chop, cut, rebuild, grind, weld, and sand, etc., etc., etc., ahead of us.
We decided to COMPLETELY REMOVE EVERYTHING and start from scratch, which includes welding shut many of the holes that would be no longer needed. Below are photos of what it looked like after we "gutted" the engine bay:
Okay....so now that you've seen that, it gives you an idea of what work needs to be performed in order to get the engine bay in a "decent" condition. Now on to to the REAL nitty gritty work!! We began sanding everything down, which included the removal of old brackets, clamps, etc. Initially, we wanted to we thought we would just "refresh" the engine bay, but it turned out to be an all-out affair and soon there was bare metal showing.
After a few days of sanding, etc. it looked like this:
This was the battery tray corner after we removed the tray and sanded it to bare metal. There were holes in the sheet metal from years of corrosion and wear (which needed to be repaired in the worst way).
After days of sanding, it was time to start closing holes which were no longer needed and holes which were caused by rust. Before moving forward, we hit it with Ospho which when applied to rusted surfaces, it resists/retards rust in chemical change upon drying to a tough, hard surface ready for priming.
While the Ospho is drying, we'll get the materials ready for Part 2!!!!
