3SGE 3SGTE Conversion possible?, Im sorry to have to ask this but please help Options

[Danohosko]

Hello, please someone shoot me i know i probably shouldnt be asking this but i cant really seem to find any solid info on the subject.

Basically i have a gen6 3S-GE (97 plate Celica GT) not a Beams unfortunately, its an st202, engine which i would like to convert to a 3S-GTE. According to wikipedia (yes i know the most reliable source in the world?) the 3SGTE engine is basically the 3SGE engine with a lower compression ratio and a turbo.
So how can i convert my 3SGE into a 3SGTE? how do i lower the compression ratio and/or just make the engine work with the turbo without causing excessive engine wear etc?

im expecting it to be expensive as n/a to turbo is but is it possible to do? I feel that the engine is good any finding a GT4 has seemed neigh on impossible to be honest.

If not possible without spending thousands of £££s what upgrades can be recommended? Im intending on a complete remap already.

Would aftermarket fuel pump and fuel injectors make a noticeable difference?

Nitrous? i looked into this but i'm not sure i would want to refill every 20 shots to be honest.

Also what about superchargers? ive read into them partially and i have a feeling they aint very good for your engine? Sort of the same as a turbo i guess but not so easily fitted for a reliable quick car im assuming?

Thanks for anyone that does reply and give me a couple tips, im not very engine orientated to be honest but i likey fast cars. Im expecting to do most fitment work myself however or get my cuz to give me a hand so labour aint an issue, thanks again.

This may be worth a read turbo a 3S-GE/BEAMS, and hopefully answer some of your questions

From memory your insurance is higher with a +T or a 3S-GTE swap than the factory turbo GT-Four over there? locals would be able to confirm.

The factory ecu cannot be remapped, There are however pre-remapped ecu's like the tom's Tec II and the C-One motorsports ecu

thanks man i'll give that a read, and i didnt realise that with the ECU so i'll look into a new one, im not worried about insurance either im getting it fairly cheap at the minute so will just hope it doesnt treble in cost haha.
Thanks for that mate

Another question, would either of those ECU's be ok to use on my 3gse as it is?

There's more to a 3S-GTE than just lower compression and a turbo. The GTE has stronger internals built to handle boost, from what I've read. There is more information in the stickies. I'd get the links for you but I just woke up and I'm surfing from my phone, which is a pain.

[Danohosko]

haha no worries man yea i guessed it was more than just the compression ratio but just wondering whether or not it is feasable really. i read that link from rusty now and aye it looks complex haha
Cheeers

not many people have those ecu's, there was a member who installed the C-One ecu for the 3S-GTE, and from memory noticed it came on boost sooner and stronger. So a more aggressive tune maybe higher boost cut/ rev cut/ speed cut. There would be gains over the rev range, but without back to back dyno runs showing the difference its hard to say how much

But once you start heading into camshafts, bigger turbo etc, you need a fully programmable computer such as Link or motec for control.


Maybe search into supercharging it or a NA build

Without overcomplicating this I will tell you , yes you can turbo or "convert" your 3sge . Pick up a stock manifold, turbo, downpipe , oil lines etc from a 3sgte , get a fmic and piping kit off eBay , sort out engine management and you set.

There are basically two ways to lower your compression ratio. Either get some 3sgte or low comp pistons or get a thicker head gasket

i don't want to get flamed for asking, but how much boost can the 3rd gen 3sge rods handle? i remembered reading a article on toysport webpage stating that the rods where the same as the gte, and i eventually plan on turboin it.
