Onto those quarter panels... I was told over and over again, no new quarter panels. I wouldn't take no for an answer!

Outer wheel housings:




Quarter panels:








This is worth posting:


Yes... I also added cruise control:




Knowing that I am the OEM guy that I am, doing some of these things was difficult for me. I've tried to stay as OEM as possible, doing things as I think Toyota would (albeit without the research dollars and casting abilities, lol). Everything on the car is either Toyota OE, TRD, or custom made to make things work.

Engine is an smallport MAP-DLI type 4A-GZE from a 90-91 AE92 GT-Z (has the nice oil drain hose and the piston squirters with the coated pistons). Came with a transmission and all the engine accessories on it, but no harness, ECU, igniter, SC relay or VSV's. Bought it here in town from someone who was going to swap it into their AE86, but decided to go KA24 (I think) instead.

Came with coils, MAP sensor, injectors, and all that good stuff, but not some of the stuff I really needed. Lucked into finding a harness on eBay that came with the ECU, igniter, VSV's, relays, resistors, everything. Beautiful! Got it shipped here.

Pulled apart the 4A-GZE, found some rust inside cylinder #1, not excessive, but it was clear that the engine had been sitting for a long period of time!

Ordered myself a new set of piston rings for the smallport, and a gasket set for an AW11 4A-GZE, plus an intake manifold gasket for the smallport 4A-GE. I honed the cylinders to clean them out and get some nice crosshatching back. Cleaned the head up and changed all the valve seals.

I'm using the RWD water pump front half with the FWD rear half. This gives me the extra strength of the larger bearing in the RWD water pump to use the clutch fan, as well as the appropriate rear housing to clear the SC12 supercharger.

I will be keeping all accessories on this engine, the car will be modified to accept the complete GZE assembly with A/C and Power Steering. Chances are I will need to lower the front sway bar and perhaps change the end links, we'll cross that bridge when I can lower the engine into the car and check clearances. Cruise control will also be functional as well.

On to the pictures.

Original largeport T-VIS 4A-GE removed:


Started cleaning up the engine bay (more cleaning/painting to come):




And it begins:



Getting the longblock assembled, with RWD water pump, and the cams from my original largeport 4A-GE:




Clutch/fan test installed just to make sure everything was fitting, other stuff needs to be installed first obviously:




Test fitting the 2JZ VVT-i ignition coils in the 4A-G head. The fit is fantastic, still need to make some holding brackets for them, but it will come:
