Hey guys, I was wondering what has successfully been swapped into the second gen XB. I'm looking for around 350 to 400 horsepower when done building with room to grow. I would like it to be a six speed auto as well so that my wife can still drive it as well. Any help you can give me I would appreciate. I would like my new box to feel like my old hhr ss I had a few years back.

P.s. I have a 2010 scion xB with a 4 speed auto

There's a 2G running around with a 2JZ,RWD swap done...

Oh wow really, I am not looking for a swap that big. I just want a swap that will bring more horsepower and reliability in the long run while maintaining the current architecture of the xB's powertrain.

350-400 all motor you are talking a V8 and RWD.

The most straight forward swap would be the 2GR-FE 3.5L V6 out of the Camry or ES 350. This is built for FWD and both vehicles have a 6 speed auto and an option for the 2.5L I4 engine so there shouldn't be too much fabrication needed beyond the motor mounts, ECU, and possibly swapping the drive train. That will get you 268HP and then with mild boost you can get into the power range you want.

This is where the problem comes into play. You're looking at custom wiring, etc. Reliability is usually not something that comes into play in that category, unless you're working on pre-80's muscle cars with just enough wiring to charge the batteries and run lamps. ;)

You might be able to get it to run till the end of time, but getting into the 300+ hp range is going to take modification, and once you mod, reliability goes out the window....usually.

Oh ill be going turbo for sure. And all I have worked on prior to this is a 1973 camaro 2002 camaro and a 1963 impalla the hhr I left stock cause I hate messing with electronics. The 2.5 swap would be coming from the Camry?

HATEnFATE

the 2.5 swap could come from a Scion tC, Camry or a Rav-4 FWD. The 3.5 could come from a lot of vehicles....Camry, Avalon, Highlander FWD, RAV4 FWD, Sienna FWD or Venza FWD.

If you hate messing with electronics, then an Engine swap in a newer vehicle is NOT something I would recommend.

Yeah I wouldn't be doing the swap entirely by myself, I am a good friend of Moe at Swift Racing Technologies and he would be doing majority of the work.

I've done an absurd amount of research into the 2GR-FE (3.5L V6) engine with either automatic or manual transmission, and it's probably the most ideal swap out there. Some reasons:

• 266-280HP stock with plenty of realperformance modifications available.
• It uses the same ECU pinout and connector so you should have little or no rewiring to do (just use the new engine harness and ECU).
• It physically fits in a TC1 so it should have plenty of room in a TC2
• I'm told the "Blade Master G" (only available in Japan) uses our same subframe with this engine, so it may be possible to source OEM mounts, axles, etc.

I was about to take the plunge and start the build myself, but I just couldn't locate a suitable donor for the drivetrain, so I'll probably hold off a few years until these engines become more common on the used market.

But this is a 2GxB...not a tC. Smaller engine compartment. Some finessing of the firewall will be in order.

k1114

No, if you compare the dimensions of each engine and look at the clearance we already have, it should fit.

There is actually a lot of space between the firewall and the block in our car. The intake manifold fills a lot of it so it doesn't seem like it at first unless you put the car on a lift and look from underneath.

I'll have to check it out! :D

If you decide to do the 2GR-FE, the Lotus Evora 400 uses it and puts out 400 hp.
If you really want to go nuts, use the back half of the Evora and make it mid-engine rear drive.

So has anyone done the 3.5 V6 swap?
