So I turbo'd my XB

[rollhard]

I bought the XB in November 04 when the gas prices started to surge. I figured at 37mpg and Toyota quality/reliability how could I go wrong. Many of you probably know me from my MR2 which made 398whp and ran 11s in pump gas. So driving the XB was like....well walking. 108hp at the crank was just way too slow. Suprisingly the car didnt drive like a 1.5 liter with 108hp. Toyotas VVTI did a pretty good job giving the little motor some torque. Anyways, I decided to turbo the car a couple of weeks ago. The first thing I noticed was even more torque! I dynoed the car bone stock and it made 89whp and 90ft/lbs of torque. After putting a 14G mitsu turbo here is my graph from my dyno session yesterday.

This was with stock intake and stock exhaust which is damn puny. I monitored the AFR from the stock Greddy Emanage and I am not please with it so I will be tuning and remapping it soon.

hehe, fanboi's and their toasters... you wanna race? my bike, uh i mean car, only makes 65hp and 45lb.ft.

[Daedalus]

That is awesome. How much boost? 63% more torque is a pretty big increase. What can/will you do for the tranny?

[DankNstickY]

haha nice. how's the mr2 anyway. you still have it?

[attgig]

figure you change the intake/exhaust, you'll get up closer to 140's, right?

that'll be pretty decent for the xB how was the mod process for getting the mitsu turbo in there?

[shoeish]

That torque sure falls off fast, and that HP line isn't very smooth. With a tune you should pick up a ton of torque after 4k rpm, which will also make those HP numbers go up.

Is it intercooled?

[rollhard]

Here are a few pics. I sold the MR2 about 3 months ago. Im still running stock exhaust on the XB so the top end gain is only about 26whp. Once I make my new exhaust, it should open up the top end a lot since the stocker is a straw size 1.5". One of the other shops we do work with has a similar set up but running 1psi more with full exhaust. At the drag strip he was able to run a 13.1. Thats not blistering fast but its pretty impressive on this little 1.5 liter. As far as the tranny goes, my clutch blew the first time I spooled. Since that dyno session, I have re-gapped the plugs which were gapped at the factory setting. I had to bring the gap down much smaller which got rid of the hesitation. Havent had a chance to take this car to the track but was doing some canyon stuff with my friend and his WRX. I was there with him the entire time so the power is there. At 2400lbs, doesnt take much to get this car moving.

13.1 sounds very fast for that little box of a car. It will pretty much smoke a lot of stock cars that people think are quick. He must have done a lot of work and had to change out tires and suspension, etc. to make it grab. <edit> Stock quarter mile is 18.7 from what I just read <edit>
What kind of mileage are you getting now? I assume that it isn't that much worse as long as your not punching it.

The car is definately peppy now. Im a little hesitant on callling 13.1 fast only because of the other cars I drive. Gas mileage dropped a little bit from 34-37mpg to 25-29mpg. My goal is to run mid 12s in this car. Why? Because its funny. I could easily run those times with the other cars but I just think its hilarious seeing this little box go that fast.

[indiglosolara]

What kind of Turbo kit is that????
is it all custom??

I would love to see pics of how the manifold looks like... what kind of Turbo and wastegate are you using..... ??

yeah.. that has me rollin' as well.


You'll definitely have to get some video of it when it's done... I'd LOVE to see that. (Kinda like that 12 second Dodge Minivan with the 4 cylinder + turbo that dusts off a camaro. )

Its hard to see the turbo but it uses a Mitsubishi 14G turbo. Cast iron manifold. The kit is about $2200 installed (greddy).

Yeah, everytime I drive this thing it cracks me up. The good thing is its a sleeper now. well except for the fmi you can see in the front

Does this vehicle fall in the "so ugly it's cute" category...

Eh, its funny looking but far from ugly. I could name a whole bunch of fugly cars from many makes but wont want to offend anyone.

Go head and say it... ASStek... ASStek... ASStek.... Ugliest by far.

(till someone supercharges or turbos one and makes it a sleeper killer. )

haha, well we all have different tastes but the asstek is one we both agree on. i think the shark from hyundai is hideous, saturns in general besides the sky, the new malibus are fugly, the new "lil" hummer is stupid looking (might as well buy a JEEP), i can go on and on...

[Apex]

You should definitely spray paint the intercooler black.

[irwin]

nice hubcaps

[rollhard]

nice hubcaps

THats the whole point. sleeper style. I have 3 sets of rims for the car already, but I just like to roll around on the stockers. Its hilarious.

[zero2dash]

Nice job. I like the concept of "sleeper cars"...good idea.
Wish I could see you beat some of these people out there rolling around in stock 'everything' cars that just put sponsor stickers on their cars like they've got aftermarket suspension, intake, cooler, turbo, brakes, nitrous, etc. and you can CLEARLY TELL that they're running a stock car when you get next to them.

13.1? let me see a slip...lol just playing...it looks sweet, that will def suprise a lot of people when you smoke them in a box!

My car doesnt run 13.1. Im assuming my car will do high 14s at this stage. I still have to do a bit more tuning on the dyno. Fuel rail and injectors are coming this week. If I can bump up to 9psi, ill be in the 13s for sure. Here is a vid from last week.

tell me about it bro. i laugh when i drive it. thats the whole point with this car. a box that is quick? lmao.

[zero2dash]

That's hilarious...
I love it.
Almost makes me want to do something similar...

He just needs Ronal Bear wheels, to complete the humiliation.



Dood, j00 just got smoked by a boxy Scion rollin on teddy bear wheels!

[shocky123]

Nice setup, you'll definitely have a blast with all the high schoolers rollin on their parents credit cards..
but the real question is..... Where's the wing ?

Gotta have a wing to make it look stock, or rather, to complete the 'I try to make it look cool, but it's stock on the inside' look.

Wow...that is really weird. And scary. And hideous. But I can't stop looking at it.

I'd have to kick my own arse if I ever drove a car with those on it.
