Engine Swap

I have a Scion xB that i'm considering swapping out the engine. I'm not sure what engine to put in it, and was wondering if anyone had some helpful information about it.

xBs aren't really the rice rocket of choice, but I'm sure with some effort you could squeeze a 1.8L VVT-i engine. But I would reather just get a nice exhuast system with a mac muffler to tone down the volume and spend more money on making it more for show and maybe better handling cuz it wasn't meant for high speed racing.

Yeah, I know their really not maid for Speed and Racing but thats why I would do it. And thanks for your input!

If you really want to race it up check if TRD has a SC for it and buy a really good full exhuast system, but don't forget to get a mac muffler. The reason I push for a Mac muffler is because they are smaller (much smaller), reduce the sound a lot, and have higher flow then any other muffler on the market. They aren't the cheapest but certainly the best. As for the suspension TRD is expensive but what I hear is that it's worth it. So check around for a SC, TRD suspension upgrades, exhaust, and that muffler I'm talking about.

macmufflers.com is the one I think.

The SC for TRD should be coming out soon. But i'll wait to see what the word is with them.

also check around for aftermarket SC, TRD tends to be a bit pricey.

Their is one that is out their already. I'm searching for info on it. Greddy is coming out with one soon , Scioned.com had one, and TRD is in the works

Before you strap on a SC you might want to beef up the gasket, that is if you're going to run a lot of boost. Have you checked out some exhaust systems?

I plan beef up everything to make sure my little engine will be able to handle as much boost possible.

are you employed, if you don't mind me asking?

Yes I am, I'm a Scion Rep.

oh ok, so you have a cash flow.
Have you looked for any body enhancements, like carbon fiber body pannels, lighter wheels, lighter seats, etc.?

Yeah they make carbon fiber hoods , fuel doors... Pretty much everything. Plus I get everything discounted. My picture on my posts is one of my cars. Its an xB with Chrome 18" BSA wheels, aftermarket TYC Tail lights, Chrome engine cover, TRD Strut brace, Billet Front Grills, AEM Air intake, Rear Spoiler. Its Alright !!

fun, what are you going to do when the xC comes out?

xA and xB both have too small hood compartments for a 1.8L VVT-i engine. Plus a swap would require ECU modification, transmission/axle/suspension upgrades to handle the extra weight, and custom mounting and wiring.

Your best bet would be a performance rebuild. It'll cost as much as a Swap, and it'll get you at least double to triple your stock hp rating.

The other thing you could do would be to find some japanese tuner sites and see what they've done with the Toyota BBx (JDM Scion xB) and try the same thing. The benefit to that is that TRD Japan will have a helluva lot more stuff for it through Modellista.

Hey thanks for your reply, I pretty much figured that i would have to beef everything up in order to handle the extra power and stuff, actualy I was planning on it. I've been in search for the Japanese sites, only problem is I can't read some of them. But thanks Again your reply was much appreciated.

goto babelfish.altavista.com and have it translate the website for you. Good Luck.

Also, toyotanation has a scion board on it, some people there may be able to help you further.

have you checked into boreing and stroking the engine?

I'm checking into everything I possibly can.

yea if you want to go all motor you probably could do a lot of head work and increase the dicplacement to 1.7L maybe 1.8 but I don't know if there are stroker kits for the scions. Getting the heads ported and polished will impove it's performance.

the other alternative, if you got $5k - $10k to just drop in a shop, either have them do a performance rebuild to max out hp/displacement (which could double the hp output, or barely get you 30hp extra), or just have a shop build a custom engine for you.
