Well guys I have decided to turbo and intercool my "point A to B car" because the 108hp just doesnt do it. Working on cars like the noble M400 and driving around 11 sec street cars at work, then jumping into the box is painful. I know many people are wondering about the turbo kits and how much power they make and at what AFR. I will be installing my Greddy turbo kit along with the intercooler kit this week. Since I have a dyno here I will be able to post numbers/gains right away. I hope through this project we can shed some light to what this car can do.

 

Yeah keep us updated on your progress and dyno #' are always good info for people.

 

Definitely keep us updated. I haven't seen a thread where someone has installed and gotten the Greddy running well. If you can get it to idle well with CEL and a 140+ dyno, I would probably buy it over the ZPI turbo.

 

SWEET!!!

 

exactly what I have been waiting for!

 

Yeah I cant wait to put that thing in. I was supposed to pick up the kit today but our supplier said that someone had put the PO in an hour before us. I will dyno it as soon as it is installed.

When you said you have not seen someone use the greddy kit and running well. what problems were they having?

 

I guess mostly the CEL. They don't mention any idling issues. Check out this thread: https://www.scionlife.com/forums/viewtopic.php?t=90679

For all I know it is working fine now...it hasn't been updated in a while.

 

What type of gain in HP are you expecting?

 

I did a base dyno run on my car. 89whp and 94ft/lbs. Im hoping for a 30-35whp gain and about 160hp to the crank. As soon as rods are available I will be building the bottom end. Im optomistic about the gains compared to maybe others in the forum who have gone FI because I have a dyno and can tune whenever I want or make any changes to the car. As soon as the kit is in, I will dyno it and log the AFR. If there is room for more boost or fuel leaning, I will do it.

 

too bad it wont be carb legal.

 

There was a guy who got rods and pistons made by Carillo for his Yaris.

I believe he paid 800 something for the pistons and 1300~ for the rods?

Custom made.

 

Keep us updated!! BTW where do you work?

 

The kit and intercooler is here. Ill try to have it installed today. The sucky thing is the kit did not come with any instructions for install. Its not that big of a deal, but it would have been nice for Greddy to specify which lines to tap in for the oil. I work at Smoothlinez. (see link below)

 

Ok, the turbo is in. Its NOT a direct bolt on kit as the downpipe flange does not align with the stock exhaust flange. The car does pull much better. Is it fast? I wouldnt say its fast but very peppy. Im still running the stock exhaust so we will be making a custom one this week as well as the intake.

 

nice, I love to see trubo on the box. have you put it on the dyno yet?

 

Mmmm still using the original air box ...

yeap cant wait to see the numbers u get.... good luck

 

Question...what is the size of the pipe diameter where the downpipe meets the exhaust? How does it sound? Stock airbox seems iffy...should be able to just remove the airbox and add a filter right?

 

I modified the stock box yesterday to make my own intake. The clutch is gone. lol. Should have known it wold be. I was going to replace the exhaust also with a Greddy or HKS system but after looking at it, there wont be much improvement over stock. The best way to go here would be to go with 2.5 or 2 3/4 piping from the downpipe back.

 

"Stylis"/Gabe/Precision Muffler has both cat-back and header-back exhausts for the xB. They aren't mandrel bent, but they are very nice looking. I believe he uses Magnaflow mufflers and tips as a standard, but can build using whatever you want.

If you search through the "Drivetrain & Power" forum you can see one of his systems that "ProshopXB" installed. Then again, you can probably have a custom system built and installed locally for the same price. Especially if you already work at a speed shop.

 

We will be doing our own exhaust. Paying for a pressbent catback is really not worth the time or money. If you look at the bottom of the car, the stock piping was not crush bent but rather smooth. The only restriction, which is very little, is from the muffler itself. An aftermarket system just frees up the gas flow from the muffler. A full downpipe back system can be put together for under $300. If you want a cat, expect to pay about $100-140 more.
