This Might Sound Like A Daft Question.

[antscelicagt]

Can i alter the drive on a 94-99 registered gt4 to just front wheel drive??

i know it sounds daft.. but hey.. it takes all sorts.

[JohnnyC]

Anything is possible with a bit of £££

But what's the point? Why on Earth would you want to make an existing four wheel drive car into front wheel drive???? I can understand (maybe) if you wanted to make it rear wheel drive.

And doesn't the GT4 put out too much power for a FWD car to handle? (around 220bhp is the limit for FWD - any more is pointless).

It can be done by taking out driveshafts ..

When the top skylines are dyno'ed they take the front driveshafts out so the car becomes RWD .. kinda makes it a better comparison for the Supras ..

johnnyc i'd like to put the engine from the st205 into my front wheel drive celica st182. i don't really want to be making a new tunnel and making it rear wheel drive.. but i'td be summat to look into..

[Bibbs]

It's the same engine as in the MR2 .. so it CAN be used for 2WD ..

[daktari]

Curious about this one. Allowing for transmission loss a standard 205 would be putting out less than 220BHP at the wheels, even in two wheel drive. But.... If you take out the rear drive shafts can you remove the rear diff and prop shaft???. And.... if you do that might you not be better off just putting a FWD or even an MR2 Turbo (Stronger box) in instead.

I know of an MG Montego turbo dyno`d at damn near 360BHP that backs up your point...... Till he hits about 120... :ffs: :ffs: is quick. But seriously scary.

[TheNissanMan]

for a 3s-gte into a 18x should be no probs....

dawsey could prolly offer some advice as he's taken the 3s-gte into his rolla (ae92 ??)....

Surely its more difficult than that???? Dont you need to lock off the transfer drive or something? When the (sorry)Corsa boys fit the calibra turbo engine and box they have to lock the transfer drive otherwise the centre diff just sends all the drive to the lightest load area which would in this case be the drive to the back wheels.

Hi,

You have few choises for a gearbox on a 3S-GTE into ST182 conversion. You can use the box from a SV21 (Camry), a ST165-ST185-ST205 (Celica) or a SW20 (MR2, turbo only). The Camry box is rather weak for the power of a 3S-GTE, the Celica GT4 box is heavy and needs internal modifying (you'll need to lock it in 2WD and weld or otherwhise block the couplings, and when you put the power on take the risk of it breaking again, in other words not the best idea), that leaves us with the best option which is the MR2 turbo box, strong enough since the same engine is run in the MR2, you can put the starter motor on it, you'll need the driveshafts from the MR2 and put the outside CVs from the Celica GT4 to them, you'll also need the Celica GT4 shifter cables and linkages.

The box from the ST162-ST182 is useless because you wont be able to fit the starter motor, unless you can sort the bell from one of the above boxes and mate that up but then you'll have the same problem as with the Camry box. Not sure if the starter motor issue goes for the ST202 box.

Cheers, Yves.

EDIT: "3S-GTE into ST185" should be "3S-GTE into ST182".

[antscelicagt]

now thats the type of info i'm looking for..

anyone got anymore constructive info.??

Are the st205 driveshafts the same length as the st182? if not, how will i accomodate thdrive to the front wheels? will i need to change the hub to? bigger brakes...

[antscelicagt]

I have just spoken to FENSPORT about this conversion. I can use the 3s-gte from the st205. i will need the gearbox from the MR2 and also the driveshafts. i have to change the wiring loom and ecu to the one from the st205 to go with the engine.

Would i be better of going with the full engine and gearbox from the MR2 turbo??

and i need to change the hubs off my car for the bigger ones off the gt4.

can't wait..

just have to find the parts now..

[Dan_Q]

Fensport are the peeps in the know B)

Just one point about the hubs- If you have a facelift GT you may not need to change the hubs, as I know they have the larger 277mm discs and GT4 callipers- So may well use the same hub as a GT4 ??

Not sure, but may be worth checking out if u want to convert a facelift- might save you a few quid ;)

[Leeky]

Dude if you want GT4 power your much better off just buying a gt4.

The money involved in an engine conversion of this type added to the value of your st182 will be enough to buy an st205

Then you have the newer shape, will last longer. No fiddiling about with the hassle of the conversion, simpler insurance as it will be a standard setup.

And forget the transmission losses, the 4wd system is a good thing. Means you can get all the power down.

Sure you will have less transmission losses if its FWD but you will find you loose a lot of power wheelspinning off the line as you cant transfer the power to the road.

[antscelicagt]

but i don't want the new shape.i want my car. i have all the tools to do the job and it's only gonna cost me £900 for the engine/loom/gearbox and driveshafts.

My car is not the facelift model, but my womans is

for advice ask ZIVK he;s the conversion specialist in this field.

Hi,

As far as the engine from a MR2 is concerned, have a look if there is no difference in the engine mounts as compared to the ones for your ST182, I'm not sure if there is any but just to rule that out. In conversions like this you'll always be faced with some surprises, only the more you can rule out from the start, the better, it will prevent losing time and save you from being frustrated with your work.

Always try to get the wiring loom from the engine that goes in and try to label and document all as good as possible, it will save heaps of time wiring up everything, if you don't want to go with an aftermarket ECU, get the one from your new engine also.

For the driveshafts, as said in my earlier post and as told you by Fensport, you will definately need the ones from the MR2.

Take the hubs as well as the outside CVs from the ST185-ST205 as well as their brake setup, you'll want their stopping power! Wise decision.

If you really want this, then go for it, otherwise you'll only have your mind haunted by people telling you it's not worth it and you'll end up regretting every effort spent on it (not dissing you here).

I sure hope you don't mean ZIVK as known on these forums!

[antscelicagt]

that ZIVK is a *^"*$£r... sorry.. but he's no conversion guru!!

ok... the engine from the st205(3s-gte) has the same mounts as my st182engine. the engine from the sw20(mr2 turbo) has slightly different mounts. i would be taking the 3s-gte and using the driveshafts from the sw20. supposedly they are a straight swap. if anyone knows of anyone who can get lengths and specs and stuff for me, i'd be gratefull.

i'd be using the standard ecu for the time being.

as this is my daily drive, i won't be thrashing it. well maybe not all the time..

i know people say it's not worth it.. but look at all those people that convert corsa 1.1's.. to 2.0l 16v.. a corsa.. WHHHHYYYYYYY??? :ffs:

at least i'm starting with a good car hey guys!! :D

anyway.. this is gonna take me a while, so lots of bike riding to work will be called for. save money.

thanks all for the support.. and don't forget.. anymore tips, i'd be greatful.

can anyone tell me, if, just by looking at the engine, how u can tell the 3 revisions of the 3s-gte engines apart. i'd like one from a later model st205.

Revision 1

Revision 2

Revision 2 - RC / Carlos Sainz

Looks the same as a Rev 3 except the intercooler is silver instead of completely back and also has got 3sgte written on the end of the block behind the starter just like the normal rev2/rev1 if i remember correctly

Revision 3

Revision 4a & 4b

If your buying a MR2 engine it wont have the same intercooler as the ones above but hopefully the rest of the engines are visible enough to draw comparision. The heat shields below the intercoolers are all diffrent which should help you firgure out which is which

[Dan_Q]

i know people say it's not worth it

I say it is! Why not be different. If you love your GT and want the cheapest way of getting more grunt then go right ahead :D I for one won't diss the idea ;)

Let us know how you get on matey.

The only problem I can see is getting the custom Badge made up- Toyota don't supply GT-2 badges

I'll get me coat

[Leeky]

Most people who do this conversion write GT Turbo on the back of the celica which is a pretty nice way of summing it up for everyone to see

[antscelicagt]

hi all..

i'm confused

option 1, St205 3s-gte engine/gearbox/driveshafts/brakes.

option 2, St205 3s-gte " " /mr2 sw20 gearbox/driveshafts/gt4 brakes

option 3, mr2 sw20 3s-gte/gearbox/driveshafts/brakes

option 4, or someone elses make up...

as u can see.. i'm gonna have to find out the proper way of fitting it all together.

When i phoned up fensport, the guy on the end of the phone was, shall we say, a little less than helpful. Twas like he was enjoyin a cup of tea and couldn't be bothered to talk to me unless i was buying something....

now.. i went to my local toyota dealers today for a touch up pen for my car. whilst there i asked about the swap, and they put me onto a guy who lives just up the road from me, whom is supposed to know everything there is to know about toyota's.

i shall go see him tomorrow.:meet: Hopefully he can put me straight.

i'll keep u posted.

Who'd like me to do a walkthrough when i get started?? :bookworm:

[codiuk]

Who'd like me to do a walkthrough when i get started??

I'd deffo be interested to know how it all goes.

Just realised I've got a SS-1 (138bhp) and not the 173bhp version. I think I better start looking for a ST205 engine too (the rest of the car is mint).

Hi,

The 3S-GTE from the ST205 has MAP, other 3S-G(T)E engines have AFM.

hi all..

option 2, St205 3s-gte " " /mr2 sw20 gearbox/driveshafts/gt4 brakes

option 3, mr2 sw20 3s-gte/gearbox/driveshafts/brakes

Option 2 is the best way to go, alternatively option 3 with GT4 brake setup.

I do.
