I am going to build a 3SGTE. (But I know nothing. Help..)

[TERRA Operative]

Ok. I've just managed to get my hands on a Gen 4 3SGTE for my AE101 Levin.

I know all about the 4AGE and 4AGZE engines, but I'm at a bit of a loss when it comes to the 3SGTE....
I'll be building this thing up over the next 12 months or so, and plan to turn it into a monster.
The turbo is gone, and it'll be getting a supercharger instead (The original engine from the GTZ Levin is supercharged, and I like the power delivery etc.)

So. Has anyone got any advice, recommended things to do, and recommended parts to use? This engine will be getting a complete ground up rebuild, so it's all open to modification.

My plans so far:

Port & polish head
Titanium valves (and retainers if available)
Upgraded valve springs
264 cams
Adjustable cam gears
Metal head gasket (TRD?)
Forged pistons
Forged H-beam rods
Bearings etc
Oil cooler etc
4-1 extractors
Custom intake manifold
Center feed fuel rail
Upgraded fuel injectors
Sard FPR
ARC front mount intercooler
Apex'i air filter
3" exhaust
ARP fasteners

etc etc.


Any suggestions and ideas would be great.

With the Gen 4 3S-GTE, and with a supercharger, I'd run it as it came from the factory.

Plenty strong enough, good headflow, and good cams.

How much boost are you planning to put through it? 14psi?

[JP]

are you really going to need bigger than the stock 525cc injectors?

[timbosaurus]

Are you going to need much more power than a boosted 3S-GTE in a light Levin

Edit: with a mods list like that, I'd be dissapointed if I didn't get over 300kw at the front wheels. 300KW in a RWD light car is stupid enough!!!

Edit2: what box are you planning on getting? The camry FWD box?

[the_random_hero]

E153 gearbox, you'll break most other boxes (unless you wanna look into EA 6 speed conversion).
Twinscrew supercharger I'm hoping, would love to see a good twinscrew build on the old 3S - 300fwkw should be easy.

Sounds like a pretty crazy project all round.

However if I were doing it I'd take it in a couple of steps. Firstly I'd get the dead stock 3SGTE (or GZE or GE -T, however it ends up) into the car and running first (mounts, box, fuel system, etc). Then once that's in there and running, get the SC working on it (SC mount and belting, IC and piping, etc). And finally once that's running well, pull the engine out, build it with expensive bits and smoke up your 300,000 fwW.

I think projects of this size get dived into headfirst, but all too rarely end up getting finished

i'm in the process of buildin mine...ie accumilating parts. this is the info i've found so far

i've gone for supertech SS valve springs and Ti retainers, SS dual valve springs, pauter rods, ROSS/ACL pistons, ACL bearings and ARP head/main studs.

with the 3s the rods are good for a fair bit of abuse but will destroy your crank/bearings if you rev it hard consistantly as their too heavy.

springs generally people get HKS or brian crower as their fairly cheap around 200-250US. i went for supertech as they came with Ti retainers (hks would prob be more exxy if you got their Ti retainers)

i've found pauter rods to be the best bang for buck rod. cheaper than the carrillo H beams and stronger and have bigger rods bolts than the eagles . strong while still being lightish

you may want to go with the ZZW30 mr2 shimless buckets.

for parts i've found a company called real street race in the US to be decently priced and quick with communication and delivery.

[Roundy]

For valve springs you can also use one of Toymods sponsors, Performance Springs.

fair bit cheaper than anything else and have been proven performers.

With a Gen 4 will you really need internals to go with it?

How big a supercharger are you looking at for it? I would've thought it will be plenty strong enough for moderate power, and going with the supercharger would you be looking at high revs?

[Cuts]

the factory gen3 and 4 head gaskets are metal
the valves are stainless and 3 angle cut factory (at least the gen3 are im pretty sure gen4 are too).

How much power you aiming to make?

[Casey-G]

I reckon you could get an adapter plate made up to suit the original e58 box, hell i know of guys pushing 40psi though some mazda piston engine and they go for the e58 boxes over anything else.


this will be an epic build if you go through with it all terra, looking forward to it.

[50RTD]

Good luck with it Terra, i'll be keeping an eye on this thread!

I do agree with the other guys regarding getting the standard motor up and running in the vehicle first with the blower on low boost and fuel system and ecu all done, and iron out those bugs before cracking the motor open and screwing some serious boost up it.

The Gen 4's will make silly power on standard internals with the right supporting mods, will certainly be enough to bag the fronts through 3 or 4 gears, thats for sure!

[SillyCarS]

sorry im not as polite as the other guys

i think its a stupid fkn idea

[TERRA Operative]

^^^^^ And that is precisely the reason I'm doing it.




The car already has a 4AGZE in it, which will be getting an SC14 with a 103mm pulley bros pulley as the SC12 is stuffed. That will tide me over until the 3SGT(Z)E is ready.

I'm not too keen on doing it bit by bit, I hate opening and closing engines etc more than necessary.
I plan to build the engine on a stand over the next 12 months until its complete, then doing the complete swap in one go.

I will be using a screw type charger, and be aiming for an 7500-8000RPM redline.
The gearbox I am hoping to use is an E58 housing, with the thicker E52 gearsets and the taller E51 5th gear. I am already building this box for the 4AGZE, before I settled on the 3SGTE, so hopefully it will withstand some of the abuse I put through it. What do people think?


Thanks for all the info, I'll start looking into stuff, and when the engine arrives this weekend, I'll start with the photos.

[timbosaurus]

The E58 will not bolt up to the 3S, so you need some sort of modified bellhousing. Safer to go with an MR2 box or the like.

Exactly hence the need to either get a plate made up to mate the 2 with a flywheel spacer*( i think one would be needed)


here is a mazda FE-DOHC mated to a e58 LSD gearbox:










So it is quite possible, and you will have a few less engine mounts to stuff with.


Edit*
Just to add these guys were pushing 370kw at the wheels through these boxes.




Edit edit *sorry terra for the hijack kinda
