So motor mounts? Same on the 2.4L as the 1.5? can you even shoehorn a 2.4L into the engine bay of a first gen xB with serious firewall modifications?
Yeah I remember hearing that it uses the same engine as the TC. Anyone ever attemped that install?

And yes, the 3800 has been in every Gm car ever made it seems like...

Yeah, and with a little bit of massaging the v16 out of the Cadillac 16 prototype fits like a glove. The only real prob is finding the engine.

Suprised you people havnt heard of this...

Just because the car is new doesn't mean the underlying setup isn't almost identical. They change many things, sure, but they keep a lot of things the same for cost savings. I could be wrong but until I can look into the engine bay I'm trying to stay open minded.

Can the 2.4 from the TC fit in the xB? Sure. Can you take the current TC setup and put it right into a current gen xB? Not directly..... Thus when the xB DOES come out with that drivetrain, they will have figured it out. If the engine bays are the same and they change out the cradle and engine mounting setups, you can get those parts and the drivetrain from a TC... bling.

I don't know why you all are trying to shoot down a GOOD thing if they keep things similar for an 'easy' engine swap. But whatever. I like to think there will be a good option to retrofit a TC engine to a first gen xB using whatever mounts/cradle/axle/axlehub setup they choose to use. What if all you have to do is get custom driveshafts made? Cheap price to pay to get the 2.4 in there and make these cars more fun.

ANYWAY... we will see I guess.

Where I think your error in judgment is is that you're assuming they'd base the car on the current xB and figure out how to fit the 2.4 in there. Why not base the car on the Camry platform, or the tC platform, or something else with the 2.4 already in it? The cost savings are still there by platform sharing, and it's obvious that the new xB is larger in almost all dimensions (including vastly higher curb weight)...I will basically eat my shorts if the 2nd-gen xB's 2.4 is any easier to swap into a 1st gen than a tC or Camry 2.4 is. Of all the cars in the stable that they could base the 2nd-gen xB on, it appears that the Echo/xA/xB platform is about the least likely that they used based on drivetrain, size, weight, etc.... I would still say that a 2.4 swap out of the 2nd-gen will be a completely, completely custom job.

overall length over a foot longer, wheelbase 4" longer, almost 3" wider track, bigger brakes all around, motor out of the tC/Camry, and curb weight up over 600lbs (more than 20% increase!) over the current model. I really don't see how much of the car could possibly be based on the current car.

i can forsee alot of people doing a brake swap as long as it is compatible

11" in the front and 10" in the back, right?

roughly that, yes. I still think spindles and everything will be different, but anything that will swap would be great.

I thought I read somewhere on this site about someone who put a 2az-fe in his box.

Alright guys, I'll let it go. I'm glad nobody wants to consider it being easier. I'm glad you all are discussing how a bike engine might be used....

Yeah... woot. Nevermind.

I'm being realistic. It is unlikely at best that this will be an easy swap. Of course, with enough money, anyone can do anything.

Its not that no one wants to consider it being easier, it just from the info that we are getting its looking to be a completely different engine.

A bike engine would deffinetly be harder regardless of what the do with the engine, lol

you never said why you want to change. Blown engine, more power, something laying around?

For more power, it would be cheaper to go the turbo route and would probably net more HP

Does anyone know, can a Corrolla/ Matrix XRS(2003-6) - the VVTL-i 1.8L engine , work in either a xA or xB (that engine works off the 6-speed manual) - I dont know what engine model # it is ? Might need a new transmission ??

v8 in a Xb?!? LSx, LTx or Mustang engine?
I always thought it would be cool to rip out the back and drop a Caddy Northstar setup back there. Just lock down the steering and make the box a rear wheel drive with 300 plus hp!

i've go a couple freinds who think i should swap my block out with a rottery block from the RX7's and then route in a rearwheel drive train all the way to the back. i told them it wouldn't fit and they said "well if he cut this out and that out and this out"... oh and they also sugjested an SRT4 aswell and make it a rear wheel drive...

*sarcasticly said* leave to a couple drifters to give you ideas of performance upgrades...

i wanted to drop a new motor for more power and thought a bike motor would sound killer and have plenty of power. but is our box really a porky. how bout a VW rabbit motor? or GTI.

and for turbo, yea i consider it, but anything else that would make it more powerful?. like rebuild and F/I?

The Rabbit motor is a 2.5 inline 5, and the 2.0T from the GTI isn't going to fit either. Man...do you know how many thousands of dollars in parts, labor, fab work, getting past the immobilizer and misc. other electronics in the engine to even get it to run, much less getting it to fit in the tiny engine bay we have to work with?

You'd be way better off stripping every piece of interior panel, sound deadening, etc... out of the box to shed a hundred pounds or two. Bike motors are also not the pinnacle of emissions...there's no way you'll pass emissions (if you have them there) with a bike motor in the car. A hayabusa motor would be amazing, though, if you could pull it off.
