Outer Limits 4x4 Board

hi ive got an 85 luxy with a 3y motor . my motor is in need of a rebuild but i thought when it was goin that is was quite slow and underpowered . can anyone tell me if the 3y is normally a powerfull motor or should i source a different motor all together . ive looked at dropping in a 308 but i already own another v8 and cant afford 2 8cyl rego . i also have a turbo here off an r32 skyline that im thinking of bolting on my 3y . would that be good enough ?? cheers for any help

the Y series engines are fucking bulletproof, they'll usually go anywhere and for however long, but they make shit all power. Don't expect to go anywhere anytime soon

A turbo *might* work but I doubt it. Would be a LOT of work.

I'd say jsut get a 3rz motor and chuck that in if you were prepared to put a v8 in.

101kw, 2.7L 4cyl (I think thats the power rating).

a good cheap conversion is a 22re out of a celica its pretty easy, belhousing fits engine mounts fit and its injected, buy a celica donor car and u have everything u need for the conversion, even the exhaust bolts up i've been involved in 2 of these conversions lately and they go together piece of piss i can even send u a diagram of how to setup the ecu if u go with it. would be so much easier than a turbo setup

i have a complete 22r carby conversion if interested
only real mod is to cut off engine mounts and fit the supplied ones
pm me if you want

As far as I can see you have two answers to give..
1. How much power do you need?
2. Is it a full rebuild or just the top end..?


If its just the top end and you are kind of happy with the power you could:-
- just do the rebuild about $100 in parts.
- Put a 4y EFI head on more power & efficency $100 + head cost & rewire.
(Both don't need to be certified +++)

Full rebuild I would rip out the 3y & replace with your choice wouldn't go the V8 plenty of other motors out there with more power for your $$$.
(Need to be certified)

I have recently rebuilt my 22r and it had same power after rebuild, and then a tiny bit less. i will say it is a bulletproof motor, after 400k, it had hardly any wear but i went ahead and got it all machined anyway. no improvement. i wanted to put a 253 in it then, and have just bought one. i wasted over a grand rebuilding the 22r and wish i hadn't. I would say spend ur money on an upgrade

Sounds odd..

Did you wear the rings in properly and not run it hard early on?

yes i ran it in proper and ran it under load. have a mate done engine reco for years and followed his advice. I think that from the 'unnecessary' machining i got done, (getting head and block machined) the cam timing could not get spot on. It is half a tooth out. along with thaat, i got it bored out 20 thou which increased compression along with getting valves re-seated. might need a bigger carby. not sure. I upgraded the carby to a weber but don't think its a genuine. anyway all that aside, i am over it and want much more power than this will ever give me. When i rebuilt the motor, all it needed was a new set of rings, and valve reseat. I over did it and wish i didn't. bring on the worked 253. the 22r is also heavy on fuel, mor than it was before aswell.

I'm not sure I would call a 253 much of an upgrade mate, why didn't you go for something a bit newer?

POWER UPGRADE. money is also a limiting factor, otherwise i would have gone the commo v6 or even a toyota v8

cheers guys . im looking to spend about a grand on either fixing it up or conversion . i can rebuild and turbo my 3y for around $800 . cheers heeps for everyones advice

If you know how to.. go the turbo beats the hell out of engineering something to fit.. just make sure you keep the temps down and the timing/fueling spot on. and dont go overboard with boost. plus it's something different.
