GT4 Engine Removal, Engine Upgrade Options

[cloqwise]

Ok a few weeks ago started taking my engine apart, i did this as i have all the parts to recon the head on order and a day so to be delivered now so i decided to take the head off first even though usually you just drop the whole engine out the bottom. Also the car club on base has no bays available and they are changing locations in october. So i couldn't be ubikd waiting around and got right to it, i haven't spent too much time on it but all has gone quite well, I went home last week as my parents moved house so i thought i would visit. I de-coked the ports and got the head skimmed which revealed something interesting. As you will see on the pictures below you can see where my piston ring blew up on number 2 or 3 cant remember now. The head was off my old block which i unfortunately took out in a crash in 2007. This made my eyebrows as the guys who did most the work on reassembling the new engine never told me about this damage and leads me to believe whether they actually got the head skimmed at all when they did it:S. My own fault really as i was no where near as gen'd up on the car as i am now. Luckily the damage is all inside the gasket bracelet as shown on one of the pictures and i spoke to the engineering guys who skimmed they head and said it should be fine so i have been very lucky there. Another annoying thing i noticed is that 2 of the valve spring seats were missing, there is no damage just a bit more scratching on one of the valve recesses. If anyone has any of these spare please let me know.


















I have noticed 2 and 3 pistons and the ports on the head leading to them are much dirtier than the others, i am guessing cause this is a centre feed inlet manifold and not the designed side feed which i think you find on the st165.

Last night put the valves in using my old collets just waiting on new ones. I needed to measure the clearance between the tip of the stem and cam lobe so supertech can work out which shims to send me with new buckets. The new buckets will have a recess in them where a 8mm shim will go. they were nearly all 5.334mm except a couple where one was 5.065mm. So i had to expose the lobe to the follower because i had no 10/40 oil i just used some grease for the lobes and for bearings as a temporary lubricant.






Just give you an idea of what i have got and what i am getting.

Already have the walbro upgraded fuel pump on it and fmic, straight air intake, a/c systems removed along with charge cooler system. Also got a bigger radiator in her along with full 3" exhaust systems and a dp with a racing cat welded into it. New power steering rad, gearbox rad and oil rad with thermostat adaptor plate to keep it at 80deg, battery in boot. cant think of what else

I have:
The water pump on it has literally done about 500miles
Oil pump
Adjustable cam gears
HKS fine tune timing belt
ferrea valves std size
supertech dual springs and titanium retainers
HKS 264 camshafts
F1 stage 4 clutch 6puck rated to 519bhp/490lbs torque
F1 flywheel (highly recommended off gt4oc.net half the weight of the std flywheel)
Head gasket set
Head is skimmed
800c injectors (just been ordered) www.flatoutrun.com Seems to be the cheapest place to get sard injectors for the 3sgte, 278 quid
ACL Racing shells, rod, thrust washer

Things on the list
Pistons and rods (yet to be decided, looking into getting some mahle pistons for a balance of performance and durability)
bottom gasket set
crank balancing and lightening
Cylinder re-bored either for piston expansion or if cylinders turn out to be a bit oval so may just bored out to 86.5
mappable ecu
Block to have chemical bath
Full servicing parts - Plug, leads, belt tensioner etc
Bigger turbo, looking into a gt3071r i think i was looking at
Lighter power steering pulley and new belt
Oil catch can
Thinking of adding a header tank and swirl pot to the coolant system but i dont full understand how it works yet so still need to research unless u can draw a diagram or explain it.
only going to take it to 450bhp

Sounds like a solid build (pretty similar to what im running)


good luck with it all.

Did you build it all yourself? I am just concentrating on the head at the moment as the garage on base is full and they are moving location in october but i cant be arsed waiting for that to happen so just going to hire a crane. It is starting to get cold now so i really need to get the block and gearbox dropped before it gets really cold. Any pitfalls you can give me a heads up on? Pity I am not in OZ i was talking to an australian lad on my base and he was telling me you can get things a bit cheaper in australia.

I have a walkthrough somewhere i wrote up for someone for engine removal in a 205. I prefer to drop it down from underneath, whole subframe and everything. Ill search around for it and PM to you.

I didnt personally do the machining or the clearances, but did the rest.

you should do the 1ZZ-FE valve bucket conversion

Afraid i can't matey as the new titanium retainers can only go with new buckets and shims from supertech, either way the valve train is going to be lighter. Its not really a disadvantage, it would be if i had shim over bucket as there can fly out at high rpm.
