1991 mr2 3s-fe new pistons

[ian1966]

Hi all, does anyone know where I could get a set of oversized pistons for my 2.0lt 16v 3S-FE MR2 don't need hi performance just standard. Also are the pistons in the 3S-Fe toyota engines all the same i.e in the carina/celica etc?
Thanks,Ian.

I can't help with that but I'd be interested to know why you want them? Would it not just be a better idea to put a 3sge engine in?

You can get the pistons from Toyota. You will need to know what mark yours are though but you can get .5mm larger pistons for the 3S engines.

I agree with Gaz above though, why not just get a 3SGE engine? They are pennies now and would give you a bit better performance for a lesser cost.

To be honest you could probably pick up a full 3S-GE engine for the price of a set of pistons for a 3S-FE, and gain 40+bhp in the process.

The only good thing about my old 3S-FE was the fuel economy lol

Personally I'm with the idea that I wouldn't do any major work to a 3s-fe engine. In fact, if your car needs new pistons, I'd be tempted to buy another 3s-ge NA, swap over any good bits onto the new car and then scrap the old one. However I don't know the full story and why this specific car is worth you saving...

I know nothing about the n/a engines (except that I have one lying about doing sweet FA). But all cars reach a point where it's cheaper to buy a good s/h engine than replace the pistons. Then -- eventually -- the engines get hard to come by and you have no option (Lancia Fulvia, FIAT Lampredi TC, etc.).

So, might be worthwhile mothballing your old one for the next 15 or 20 years..........

Thanks for all the input guys, one question is the 3sge engine a straight drop in or are there complications i.e. wiring loom/ecu etc? I was thinking if I did a complete rebuild of my 3sfe engine at least I would know what I had got.
Cheers,Ian.

I'm sure if someone is breaking a rev 3 with the the engine, wiring loom and ecu all sat in one place then you would just replace the lot from one car to another...
