What a lovely way to spend a day - pulling the motor and box out of the 4
![]() Dropping the subframe... Subframe and exhaust removed... Driveshaft out... Engine and box just about ready to come out (loom was the worst part!) Part of the WRC version's antilag system... With the motor resting on 'supports', the car was hoisted upwards... Thanks to my mate for the use of his workshop ![]() My, what a big gap! Uses for Holden Ute wheels #24 Looking a bit sorry for itself right now :cry: Next step is to start pulling the motor and box apart so the real fun can begin ![]() Gary This post has been edited by GT4WRC: Jan 17, 2006 - 1:17 AM -------------------- ![]() 1994 ST205 Celica GT-FOUR Group A WRC - running in new engine 1993 Rover 220 GTi tarmac rally car (under construction) 3SGE power here we come....

Was lucky enough to get my hands on a cylinder head which had been gas flowed by NZ's top Toyota guru. It had been previously used in an MR2 which had a dyno proven 450bhp. Head was 10,000kms old and came complete with HKS 264 cams for a price which was too good to be true.
It is actually from a 3S-GE motor which Toyota originally fitted in their factory to an Altezza. When I got my mitts on it, I sent it to a local head specialist who cleaned it up and pressure tested it. New valve seals were installed, valves re-seated and uprated valve srpings fitted due to the rev limit being increased to 8,000rpm. There are a few minor differences between the n/a and turbo heads which meant a couple of bits of creative engineering were required. The GT4 uses an EGR (Exhaust Gas Recycle) system as part of its emission control which requires a slightly different valve cover. As a result, a small piece of ally needed to be welded between #4 spark plug hole and the end (as can be seen in the photo below). Otherwise there would be a gap for the oil to splash out. This is due to the EGR 'feed' being at this end on the turbo head. Also, the 3SGE uses top feed injectors as opposed to the larger side feed on the 3SGTE. So the injector holes needed to be re-drilled to accept the larger injector nozzles. A fair bit of work has been done on the inlet and exhaust porst to improve flow as can be seen in the next two pics... As well as increasing power, should also reduce lag quite a bit too ![]() Also, decided to 'tart' up the alternator too being as it is in such a prominent position. So it was stripped right down to its single components... While it was apart, new bearings were also fitted. And the finished article.. Amazing what a bit of chrome can do ![]() Gary -------------------- ![]() 1994 ST205 Celica GT-FOUR Group A WRC - running in new engine 1993 Rover 220 GTi tarmac rally car (under construction) 3SGE power here we come....
