G'day
I got a 1990 Camry as a second car I was havin a geek at it today and though fuck it I want to put either a small turbo, or supercharger on it,as it looks like there's a bit of room at the front of the engine, I don't want to put a nu engine in, or build a engine up, just bolt it on old school style. I wanta run around 6 psi boost I am only looking for a small increase in power,and wanta spend bugger all on it , as this is just a bit of an engineering project for me and a chance to get in the workshop and fuck around with the tools. I have mucked around with 1J's and 2J's, but never put boost on a ATMO engine.
If someone has done this , any info would be great, I don't expect it to do 8 sec quaters, or break the sound barrier, I'm 37 and have other things for that, I just wanta project
Regards
Roy

Hey mate !
I had a mate who was about to attempt this,he had all the parts and everything but he pulled out.The main starting point would be to get your hands on a 3S-GTE manifold.I hear they can pretty much bolt in the place of whats already in the 3S-FE.If your after more info regarding this type of conversion head on over to www.toyotanation.com a couple of people on that site have done this.
Hmm dont know if he frequents this forum very often but someone nicknamed Da_Horse on that board is in AUS and I believe he is also attempting this.Not sure if he is still continuing but if you could track him down im sure he would be of some assistance.

i ish here
project is still going forward, elbeit slowly as i build up funds so that i can do it properly. i'm also taking care of a few other modifications that i may need to before i do the conversion.
parts wise you will need:
st165/185/205 manifold and turbo and dumpipe.
oil lines to and from turbo
water lines to and from turbo (if you choose not to do this you will definately need a turbo timer)
fuel management unit
gaskets for manifold, oil lines etc
Process wise:
your engine needs to be in good nick, and due to the camry having a 9:1 compression ratio you have to realise that too high boost and you can say good bye to your engine. i'm actually goin to do a rebuild before i turbocharge the 3sfe and i'll be making sure that it will handle the boost. how many km's has your car done? have you got in mind what kind of fuel management you will be using? even if you just get a piggy back ECU and adjust some of the fuel mapping of stock ECU you will notice some increase, as the 3sfe has a slightly lean lower end, and after 5K rpm, it runs rich....if you adjusted it a bit so that the A/F ratio was more spot on then you would feel some difference.
if your adamant on turbocharging then go for it but remember that you will need to spend some time tuning the a/f maps to ensure you dont end up with melted pistons.
Cheers

G'day.
Thanks for the replies!!
The engine has around 50,000 k's as it has been rebuilt the car has 200.000k's on it and is in good nick,
Can you tell me how your going to set up your oil and water lines for the turbo?
Once again thanks for the input, it will be of great help
Regards
Roy

Wouldnt you be better off to just drop in a 3sgte?
That way you get the ecu to control it too.
Something to think about.

what kinda of rebuild was undertaken? general rebuild or complete tear down? i think for 6psi it should be fine...
oil lines i'm going to be using a some st205 oil gear (pump, sump pickup, etc) so that saves me from tapping a hole into the stock sump. i'll have to get back to you in regards to where you would get the inflow line from, i know out flow is fine and easy as its just from the outlet on the turbo to the sump.
cooling lines i was goin to tap a line from the water pump into the turbo and then out back into the radiator. but i'm not 100% sure of this yet as i havent got that stage yet. essentially just tap a line in from after the radiator then make the outlet line go back in before the radiator. i think you should understand that...kinda of if your not clear on any issue just let me know and i'll reclarify for you.
any thoughts on fuel management? i'd also suggest an intercooler, just use a stock st185 one and you'll be fine. i think there was one on sale recently for $50...you might need to reweld the inlet/outlet but shouldnt be too much.
there are a few other things you need to address too (eg wastegate acutation, get a BOV or a recirc valve etc.) its easy in concept but expect to spend at least 1000. i know parts alone for me is 600 for just the turbo and oil gear. also you'll need an exhaust shop to fabricate an exhaust system or you can ask for them to make a adaptor pipe from the dump pipe out let to your stock system (cheap option but i dont know if it will be effective).
one other thing is that you need to realise the gearbox might not take the increase in power. i'm not sure what may happen, but keep it in mind.

this is an easier option, or even dropping in a 3sge (even a gen1 would make a difference). going the custom 3sfe-t route is costly but unique. an engine swap would be much easier ( 3sge or 3sgte) as the engine mounts are similar. if you want to stick to 3sfe, then you can try and find one from say a late model corona, they have slightly more power.

the 3S-GTE will be qucker and cheaper
costly and unique only turns heads, it doesnt win races.

This is gonna be good...da_horse with his 3SFTE...another 3SFTE and oneday maybe my 2VZFTE...
I'd say go custom 3SFTE all the way. Although the 3SGTE swap is the 'better' way for say racing or something, because of it's easy interchangability and parts, the 3SFE will produce enough power for it to be quite fun and of course, unique. I don't think he is after winning races, so go for the 3SFTE. I'm with you all the way mate.

If you wanna go full-custom, there's plenty of 2nd had 2 Litre turbos around, off silvias, WRXs, etc. etc. -If you've got the short cast exhaust manifold like my 5sFe (with the cat hanging off), you can get a short pipe made to connect the turbo to the bottom of it. if not: dunno. If you've got the twin down-pipes then I guess get an exhaust shop to make a Y-collector into the turbo housing.
You'll have to think hard about heat shielding, as well as intercooling of SOME type to keep it all together, running stock N/A compression. I've read a couple of articles on people using a fifth injector just after the throttle body, run in a closed loop off the O2 sensor to keep the stock injection from leaning out, without having to mess with the stock computer.
Sooooo many ways of skinning the forced-induction cat.

AHH thanks once again for the replies!!
I been thinkin about taping in to the oil pressure switch with a T piece to feed the turbo, and just pull out the dipstick tube and braze another pipe on to it so the oil can return
I got a mig and all the gear to make the dump pipe thats OK, And I have all the oil lines left over from other turboed projects
I like the idea of another injector, might look it ta that sum more, I'm not 100% sure what to do there yet,as I have never turboed a atmo engine before.... learnin...I may just run a piggyback FC
This project is a very low buck, build what I can, I only wanta run 4-5 psi and I don't rev the fuck out of the thing, just cruise around
Thanks again!!

I'm not sure about tapping oil from the engine's supply to feed the turbo. If the main bearings run low on oil pressure (cos it's going to the turbo) then it's bye bye motor. Likewise if the turbo starves for oil when it's spinning hard: I've seen what happens and it ain't pretty! ! -If you're unlucky it'll spit bits of the compressor wheel + blades into your motor too . . . messy. .
Find out how factory 3sGTe's feed the turbo, and whether they run a different oil pump/pump internals etc. etc. -If it's different you may be able to get the factory setup from a wreck or Toyota spare parts - and know you're safe on the oil-front. I'm no 3sGTe expert, so I can't tell you any more than that sorry.
Oh - you also need a good VOLUME of oil to the turbo - not just pressure. You also gotta have a big return pipe to allow for foaming. The return oil will be super-hot too, so you may wanna run it through a small oil radiator on it's return to the sump. Perhaps through the AutoTrans heat exchanger in your radiator tank if you've got one, and the return pressure isn't too high (Don't wanna blow the tank and force all your oil into the coolant!).
Heat management is a big issue, so the engine itself may also be marginal for cooling capacity in summer, with the extra heat from bigger bangs in the cylinders.
Not tryin to scare ya - Hey, you probably know most of this already! Just trying to give you something to think about over xmas, so you'll have a better idea of which questions to ask people in the know.

Hey
i've got a 1988 camry with the 3sgte from a st205 gt4 in it. It is under the members rides on here somewhere. Another guy on this forum has a similar setup in his sv21. He is running the stock 4 cyl gearbox and as far as i know it is still holding up ok, I think he had some CV issues though. I know of a widebody camry that had a 3sgte, big boost/front mount/exhaust with the stock gearbox and had no problem either. I am running the V6 box just in case but i have never heard of a broken 4 cyl box, be gentle with it and I think it would be fine.
I am still using the original camry radiator and cooling fans with mine which makes about 180 kw at the wheels, the fans only come on when you stop moving for a long time, so i wouldn't worry about the cooling system as long as it is in good condition and the fans work.
I would get an o2 sensor and a cheap display before you touch the motor so even if it isn't totally accurate you can keep an eye on the air/fuel ratio as you add boost. Then you will know if your injectors, air flow meter, fuel pump etc are big enough.
These cars are awesome fun with boost definatly worth doing
let us know if you want any pics of the factory oil and water lines etc from the 3sgte and i'll see what i can do.
I also have a few spares left over from the conversion.. complete 3sfe and ecu, 4 cyl gearbox, air flow meter, extractors and a cheap 2.5 inch exhaust that has been cut in middle, motor burns a bit oil but runs well. The top half of the extractors could be a good place to start for a turbo manifold.

hi, AAAAAAAAAAAAAAAAAhh,
I've been tellin you guys it's a 3SGE...NO.it's a 3sFE,... apoligies people, I'm new to 4cyl toyotas...... I know my 6cyl 1j's and 2j's no prob, but not my 4cyl.... anyway will a 3sgte exhaust manifold still fit??

I "THINK" the ports are a bit different - as it's really only the heads that are different between these motors. Can't say for sure tho . .

Hi
I am Albert from M'sia, I realy intrested with your project SV21 to 3SGTE.. coz I have a plan to do so...
Can you pls provide me a full detail & some picture for guideline...
My car is Toyota Corona (ST191) 2.0lit (AT).
I wonder to swap Celica ST205 (AT)into my car..
If I purchase ST205 halfcut, can I "Lock" the 4WD gearbox to FWD...
Understand from Forum here, can choice SW20 MR2 gear box...
but how about ECU, & drive shaft?
thanks
hope to see your reply soon...
