Gen III 3S-GTE WRC build - Finished! Options

[nik]

i wish my shop went that fast

It helps when you actually do 99% of the work yourself
Gary

i only did about 50% on this project but 100% on my old 7afte

[GT4WRC]

what kind of rods are these? Might be usefull for me too to have some high quality parts in my engine

cheers Joerg

OEM. Shotpeened and polished.

thats pretty fast indeed. Pretty soon your gt4 going to be a monster!

[snakeloa]

So tell me Gary, why only OEM Rods and not some uprated ones???

What is the difference after having them Shotpeened and polished?

Thank you Joerg

[Bigmeanbulldog55]

Lookin good.

wow ... that first pic.. just brings a tear to my eye....

I'm not after 'silly' power so standard rods will be more than adequate. Shot peening is meant to 'de-stress' the rods and teh polishing simply smooths the surface. Probably a little overkill, but as I'll be increasing the rev limit to 8k, thought it prudent for a little added security.

I'll be extremely disappointed if it's not

It's damn frustrating for me TBH as I'm still waiting for the TRD main shells to arrive. Otherwise would have had the bottom end completed this weekend

Will be running HKS 264 deg cams with adjustable cam wheels and a 'race spec' cambelt.

Cool.....im doing a 5sgte project with 272 toda cams and adjustable cam gears....cam sensors and quad coil packs....

where are you getting your cam belt from ....(as im on the same side of the world as you)....would be interesting..

[GT4WRC]

The one thing that has been holding everything up at the moment has been the TRD main shells. They finally arrived today - at least 8 of them did. The centre bearings weren't sent out due to a mix up so won't be here until tomorrow
Still, with the other shells, we could measure up the crank to see if any machining was required. Forget the measurement, but a miniscule amount needs to come off the crank so off it went along with the block to the engine reconditioners. Expecting everything back tomorrow.

Shell sizes being measured...


Stuck at work all day tomorrow, but hoping to have the bottom end completed on Thurs evening.

In the meantime, took the opportunity to clean up the gearbox. After 11 years use, it was absolutely caked in cr@p..




So out came the industrial strength cleaner, a stiff wire brush, hosepipe and lots of elbow grease. Here's the result...




With that cleaned, new driveshaft seals and release bearing were fitted. Clutch release slave unit was looking a little worse for wear so a replacement is on order.

Nice work on the tranny. It looks brand new.


Good luck

Excellent clean up
So much time & effort "clap clap clap" keep it up

[Bigmeanbulldog55]

You should compile all these threads into one for your "build up." That would be neat. It would be long but it would be easy for a year down the road to come back and find it and look through all the things at once. I've already lost track of some of the stuff you've done.

wow talk about a tear down and rebuild.

are you gonna send the tranny to a reconditioner? you might as well do it while its out of the car.

No need. Drivetrain was running flawlessly and the oil which drained out was nice and golden.

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

Dear god that is hot! Lucky!

[Bigmeanbulldog55]

All this stuff is looking good. Are you considering my idea of making it all one big post though? Seriously, it would be nice to see everything you've done together. Jumping from post to post to check everything is a little annoying. I'd really like to have that stuff done to my car one day. Actually, I know I'll have that stuff done, it's the car that's in question. Keep it up.
