1GGTE Vs 3SGTE

[RAd28]

is there any kinda articles comparing these 2 engines??? power, physical size, weight? i'm kinda thinking that maybe the 3S would have been a wiser choice for conversion since it's smaller (i think) and could have been put further back in the engine bay... so as to keep a nice balance...

opinions people?
anyone got a RA2X and a few engines?? i'd be more then willing to experiment for the sake of Toymod-ieness

been in mine pretty stocko and supra with IG. found bout same amount of power, bout as quick as one another just that the supras 1G was more smoother with power coming on. theres heaps of docs id assume on both motors on the site.

which gen of 3s?
the later ones have the advantage of better tech than the 1g. of course, bang for buck you gotta look at all the hassles involved in converting the 3s to RWD (for great info re: 3s -> rwd in an old celica, PM cool1.. he's done it)

[Jorrs]

yeh thats true the RWD factor, for all the bother maybe the 1G would be the better choice.

[RAd28]

well i don't know a great deal about the 3S's, so i'd be looking to compare them on the ground of availability and cost... if you can get the latest gen (3 or 4???) for roughly the same dough as a gen 3 1G... then that's what i'd be looking at..

[RAd28]

well i've seen the 3S converted to RWD more then once... can't be that hard can it???

[Draven]

that depends on what you consider hard
I certainly wouldn't call it easy tho

1G rwd difficulty = putting a glove on your hand

3S rwd difficulty = putting that hand up your bum bum.

3S rwd difficulty = putting that hand up your bum bum.

*SCHLOOOP*

well that wasn't so hard...

now i gotta go wash my hand...

^^ dude... you'll never live that down!

The main difference making for greater difficulty is that the only 3s with a rwd box is the IS200, and a 6spd box, flywheel, and clutch wont be too cheap and thats if thats the route you choose. Then if you go a cheaper route you need custom mounts and just about custom everything.

As for weight i have no specific numbers but i cant imagine too greater difference as the 1G is still a small 6, i'd imagine 20-30 kg more at most. Power figures are quite similar 3S rated between 185ps to 245ps (taken from Here) from my search but i think the later is a little modded. 1G rated at 138kw - 157 kw as stated Here

I think the 1G is a simpler choice which is why its so much more common. 3s is cool and different though. Go for it

as for hp, from the latest OST dyno day hamgatan's 3s was almost = in power to my 1g

[RAd28]

benefit i see with the 3S is that you could shift the weight back in the engine bay... i've already done the 1G conversion, but i wish i could have my handling back... 20-30kg is heaps.. imagine sticking and a half of concrete in the engine bay... power i would expect to be similar, as for getting a altezza 6 speed... sure, might be expensive, and rare.... but dammit! it's a 6 speed

ahh well, i think i'd rather go that way if i do it again... that or cut the firewall and sink the engine way back in the engine bay...

The gearbox isn't a problem for a RWD 3S, you can use a plain old W58 with a bellhousing from an SA63 Celica and you're good to go.

As for the rest of the conversion, it might sound like it's a simple thing to do but as a few people have discovered it just isn't. Do a search, there are a few detailed threads on the topic which will give you a good idea what's involved.

While I agree the 3S is a better engine, the 1G wins hands-down on the bang-for-your-buck scale. Forget the price of the base engine, it's the cost of the conversion which is the killer here.

Ok

I have done several of these conversions (3SGTE) and I have to say it is well worth the effort, my conversions have all been into AE86 or KE70, I have used the ST165, ST185 and ST205 engines, the pick is of course the ST205 or ST215 engines, yes there is a fair amount of work in the conversion, but either way you will have about the same amount of work to fit either engine. The secret to doing the 3SGTE conversion is to ensure you do all your home work and source all your parts and do your trial fitting before you fit the engine into the car, ie inlet manifold fabrication, turbo manifold, make sure your clutch is the correct one, modify the distributor and convert to crank angle before the engine goes in, make up your engine mounts and mounting plates ect ect, if you do all this before you put the engine into the bay it is a relatively simple converion. You will however have to run an after market computer as there is no way of using the standard distributor set up, with out major fire wall mods. The benifits are the minimal weight increase over say a 4 age, the abitity to make good power easily and reliably, the AE86 with the ST165 engine made 240rwkw reliably for over 35,000kms with no internal mods. So for my money the 3SGTE is my engine of choice, I am sure some one will give you there opinion in a similar vein to support the 1G so read both weight up the pro's and con's and make your choice, but if you need any further info please feel free to ask.
