Do you really have to worry about tossing out the stock 1.5 and 'ruining' an xB?

Yes, I think it's silly and wasteful to buy an M3 only to pull the motor to swap it, but the xB is priced so that the new car and the motor of your choice could be a reality for less than $20k. And nobody's really going to cry over the stock 1.5 going to 'waste'.

The only hesitation I have about buying an xB is the weak motor. Trying to turbocharge an FE Toyota motor is not the most reliable idea out there. Swapping in a slightly larger n/a 4 banger (2.2 - 2.5 liters) would be a great, realiable way to make this car acceptable transportation for a lot of people.

why does everyone always make these forums into something that they are not. who cares if you don't think the box is a racecar. who cares if you don't think an engine swap is useful on a new car, etc etc (sorry i singled those out, just the last ones i read). there was a question that started this topic, and people wanted an answer, not to hear you saying that its not right. they want a bigger engine cause they feel that their xB/xA is to slow. they didnt say that they want to go drag race a supra or a viper. its the whole reason why cars are so popular, and why we love them so much. upgrading whatever we have. consider that maybe people just like the way the box looks, but not the way it drives. individuality. that's what scion is all about. oh, and btw, the only engine that will maybe fit (although you would need custom motor mounts at least, probably more) is the corolla engine (mr2, matrix, and celica). sorry i forget the code for it.

 

The problem here is that some posters have no clue what they are talking about. Porting and polishing an intake? The intake is plastic and the interior is the ideal finish to start with, the ports are perfectly matched as is the gasket. These motors do not compare withyour lawnmower, Uncle Bubbas' 55 Chevy, or your buddies 10 year old Honda. I have a little experience with Toyotas and would be damned impressed to see any pictures you care to post of your successful motor swap. Until then , sweet dreams...........

 

I hate to dredge up an old post but I have been doing the research like you are talking about. I have been thinking about swapping in a Celica GT-s motor for a while and here's what I have come up with.
Engine: You would need a donor motor. The cheapest that I have found the motor online was 1200 dollars. Thats without an ECU to control it and the VVTL-I and without accesories i.e., power steering and a/c. Also, I'm still digging on this but do the ECU's in these cars tie into the whole car. Things like ABS, VSC, TracControl. Are these all subsystems that have anything to do with the engine's ECU. If they do then using a Celica ECU and engine is out of the question. This motor pumps out 180hp before being modded. In comparison to the 108hp the Scion motor puts out, or even what the Blitz S/C or any turbo on the Scion motor has yet to put out. Nitrous guys we know what you have so hold on a sec.
Transmission: The stock Scion transmission part number does not cross with any Celica transmission part number. I'm still researching this. I thought about your idea of using the Scion gearbox, and seeing if the bellhousing from a different transmission would bolt to it AND the motor. But I need access to the parts to see this and I'm still working on that.

I'm really thinking about this. Why would I want to destroy the stock wiring harness and everything. It's still under warranty. If I pop the motor with a turbo or S/C I'm screwed too. Like I said, it's in the air and probably won't happen but it's an idea.

Flame Away

 

i can count the IQ of this thread on one hand..

specially the "the 3SGTE engine is too old, it wouldn't fit" comment..

cuz aparently as the engine gets older, it grows right?

LMFAO at this useless thread.

 

Someone tried fitting a 3sgte in his xB and the AC and power steering wouldn't fit...so he took it out. I think it got too old.
