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

[GT4WRC]

very nice build here. what is the plan for engine management? piggy back on teh stock ecu or are you going for a standalone or pnp ecu?

Apexi FC ECU which is modded by Power Engineering in Japan for use with the ST205. Placed an order last week for one and it should be ready by the end of Jan 06.

Beautiful. Really.

are you worried about clearance issues with the koyo ? It might be a very tight fit...

After fitting the rad and the Kenlow fans, I have gained an extra 50mm clearance

jezuz gary, enough work eh? Looks great though. All in all how much $ r u spending on this project?? Im guessin a good amount. This things probably gonna be bulletproof though. For ur transmission/gearbox, are u just using the WRC spec gears? or are you gonna be changing the gear ratios. Also you doing LSD's front and rear when you move to the rear diff?

I might have missed it but what turbo will you be using Gary?

Transmission will remain standard (other than the clutch). Rear diff already has a Torsen diff as standard.

GT30.

Can't wait to see your beast up and running man, it'll definitly be a monster.

After the 'bore scoring incident', I decided to get the block ultrasounded to check if it was safe to bore it out to 87mm. Some cylinder walls on the earlier are as thin as 2.5mm between #2 & #3 while others are 4.5mm. As I said above, is a simple case of pot luck. Later blocks were revised with the thicker walls.
Tests on mine, which I got back today, show 4.3mm thickness so boring out to 87mm is going to be okay after all.
I'm off to Europe for 3 weeks Sat am so the bottom end will be all sorted out for me when I get back. Something to look forward too

That's absolutely great work you've been doing there Gary. Big props for you. I just hope that one day i can do such work with motors that you do or even a little close to it. It's just so impressive. Wondering how difficult would it be for me to turbo my 3S-GE or just swapping the 3S-GTE and btw still don't know which one would be the better option for me. Read that your coming to europe also. What's your location?

damn i gotta wait 3 weeks? haha, have fun in europe man

While I was swanning around Europe, the new pistons were successfully fitted to the revised block....





... we couldn't get some ACL +1mm pistons so turned to a set of Wisecos from the US...



So, with that part completed, I could now start putting everything back together..



ARP studs fitted along with the new HG...



Oil pick-up and splash pan fitted following a few hours in the acid bath....



New crank oil seal fitted....



Due to different cams, altered CR and different pistons, a test was required to ensure that valves and pistons didn't come into contact with each other so off to the local toy shop for some...



This was then put onto the piston crowns where the valves would likely come into contact...



Once all 4 pistons had been set so they sat half way up the bores, the cylinder head could be fitted and torqued into place....



The top cam cover backing plate and lower belt cover were fitted next to ensure that the cam wheels and bottom pulley were positioned correctly....



.... prior to the cambelt being fitted....



Once everything was properly assembled, the engine was carefully turned over for a few revolutions, taking care to ensure that there was no unwanted resistance.

Then, the belt and head were removed so the doh on the pistons could be inspected. This revealed plenty of clearance between pistons and valves. Obviously a good thing....



With the doh removed, the head could be refitted. This being the current state and the end of play today...



Work prevents me from doing more until Friday morning when the rebuild will continue. Watch this space

Wiseco pistons rock. You won't regret them. Great job and we're all looking forward to seeing that beast put out big numbers.

Managed to skive of work this arvo and managed to get quite a bit done.


Finishing off fitting the sump to the bottom of the motor...


... including a nice shiney powdercoated sump pan 8)


Genuine parts where possible. New belt and idler and tensioner wheels...


... finished off the camblet side of things...


... allowing the bottom cover to be fitted.


OE fuel rail (for now) was bolted on. As this was originally a 3SGE head, slight mods had to be made - including the injector holes which needed to be enlarged to suit the 3S-GTE injectors.


Then the inlet manifold could go on.


To the front and fitment of the alternator bracket and bling alternator


State at the end of the day. Loom is now partially fitted along with numerous hoses etc. Really glad I took lots of photos before I stripped the motor down





Need to adapt the cam cover slightly as I can't use the centre throttle body support due to the lack of castings etc on the n/a head. No real issues asthere is plenty of other support. Once that is done the cover can be fitted. Then, hopefully, time to fit the box. More to follow tomorrow
