Turbo 1.6L Question - Toyota Nation Forum : Toyota Car and Truck Forums

Createdtoburn · 11-13-2006, 02:29 AM

Alright, I have a 92 Celica ST 1.6L Manual. Basically, I'm thinking of turboing it. I dont know if this has been asked before, but would it be pointless to turbo the 1.6L engine? And would a manifold from an Alltrac bolt up to my block?

So if anybodys ever done this or thought of doing it, I guess I just wanted to look a little bit into it before I consider the idea. I know anything's possible, just curious to wether or not it would be worth it.

Any info is appreciated! thanks

First off how many miles? SNAFU on ctech turbod his on stock internals with a nice t3 and it ran great, pulled better than most 3sgte swaps because the cars so light.

My 93 STX is turbo, but my engines burning oil so I dont drive it (last owner never changed oil, found out when i opened the head up.)

You can get a manifold off ebay, just type in 4afe and youll see one or two t3 style manifolds. You need injectors(look for black supra injectors, they are 440 cc and it will idle fine), get decent engine management, for the price of a new SAFC you can have an emanage that will beat the SAFC in every catagory. Then you need a map sensor and I recomment a fuel pressure regulator and fuel pump.

If you want to go beyond simple power, look into some cams, that will open her up nicely

Would the stock turbo manifold from the alltrac engines fit on my 1.6L block? Like, could I buy these...

And bolt it up to my 1.6L 4AFE engine?

By the way, my Odometer says it has 253,000 miles, but I dont believe it. The engine runs too good and doesnt leak ANY oil or burn ANY oil. I'm just thinking of putting a BB turbo on there so I dont have to run any oil lines or anything. Just make my own piping. All I need is the headers, a turbo to fit on them, and a downpipe and im set I guess.

Luckynumber5 · 11-15-2006, 11:17 AM

No, that wont fit, buy one of the ebay $100 manifolds, uhhh, bb turbos need oil too...

You have about another half a year of research ahead of you before you go fooling with that engine.

Createdtoburn · 11-16-2006, 09:44 AM

Wtf? I heard BB turbos dont need oil because its like a sealed ball bearing turbo... kind of like... sealed bearings in bike cranks. Maybe my friends are just dumb. But I know how turbos work and how to hook one up. We just finished putting a front mount intercooler in my friends turbo-coupe thunderbird yesterday. His car is killin mine now, and he doesnt even have a license haha.

I really want a turbo on this thing.

Start gathering parts then man, and plan on the car being down for a bit.

Createdtoburn · 11-17-2006, 02:08 AM

So how hard would it be to put in oil lines? hah. I know this is possible because I saw a guys car on Cardomain, was a 1.6L turbo.

Luckynumber5 · 11-17-2006, 04:33 AM

You either drill a hole in the block and tap it for a fitting then get an oil line that screws onto the fitting and to your turbo. Or buy an oil filter relocator with accessory oil ports for guages and stuff and just tap off one of them, but you will need a restrictor. Youll need an oil filter relocator no matter what though, i dont think theres a turbo out there that wont hit the ctock location.

Youll also need to drill the oil pan and route a return line from the turbo, its gotta be a good size line and it should flow with no kinks or restrictions.

Createdtoburn · 11-17-2006, 05:23 PM

Yeah I wasnt sure why the oil return line is so much bigger then the feed line. And I dont need a oil filter relocation kit. My oil filter mounts from under the car. It's not like the 2.2L engines where its right in front. It's the 1.6L remember? ;-) 4AFE.

So I would drill a hole anywhere in the block? lol. Whats the best easiest spot to get to I wonder...

Createdtoburn · 11-18-2006, 07:58 PM

Alright so what if I just bought this kit http://www.jcwhitney.com/autoparts/I...35673310559551

and put a fitting on the feed and return line to the oil filter and just ran those to the turbo? Dont see why it wouldnt work?

Createdtoburn · 11-18-2006, 08:06 PM

hah sweet. so I supose this would work also correct?

Same engine, different car. Right?

Luckynumber5 · 11-18-2006, 08:20 PM

because when the oil goes into the turbo it hits a high speed bearing and gets frothed up like chocolate whipped cream, and its no longer pressurized, it has to gravity drain back into the pan. You can run the feed line from the filter to the turbo because its pressurized, but the drain has to drain from the bottom of the turbo into the oil pan.

that turbo kit will work yes. but you may need a small amount of customization, i dont know if the exhaust lines up right of maybe some other small differences.

Createdtoburn · 11-18-2006, 08:57 PM

So basically I can run the feed line off the oil line to the filter, and just make another inlet to my oil pan for the return oil line from turbo. And I was going to have the exhaust done at this place nearby for pretty cheap.

So with my stock engine I could do this safely? Whats the most PSI I could run safely? Like 6?

Luckynumber5 · 11-19-2006, 03:20 PM

cant really say because 1 psi doesnt equal any set amount of airflow between two different turbos. I wouldnt push it past 6 or 7 on anything though unless you have someone that really knows how to tune. Remember to cut your ignition timing back a few degrees, or buy a msd ignition unit that will cut some timing per psi of boost. Real important if you want that engine to last.
