A truly inspiring and smart build! Nice to know that other than rods and pistons these little engines are so robust. The plans I have for my XB after next smog inspection February is a Blitz supercharger and piggyback fuel management on stock internals. While I'm enjoying the modest gains I'll see from 6 lbs. boost, I plan to build another engine that can withstand the higher boost I can get from a turbo. I'll be sure to take a clue from you and change out the valve springs once the rev limiter is history. Looking forward to seeing the dyno pull once you get a new turbo sorted out and if it's reliable as the last build.

I found out today why my 6 month old turbo failed. The oil feed line restrictor had a peice of debris in it, which cut off oil flow tremendously. I did an oil change days after installing the head, but that was probably too late. Also, I have my oil feed line going to a oil filter sandwich adapter, which is pre filtered oil. So lesson learned, turbo oil supply should always come from the block.

Hey just an update... Im going to swing for a gt3076 this winter, but in the mean time I installed a $200 cheap turbo of similar dimension to my Garrett t3/4 50 trim which just failed. Im VERY AGAINST knock-off parts, but Im committed to attending a time attack this weekend. Im running 26psi (4psi less) because I don't want to go too hard on this turbo. Numbers are good , and notice that the car makes power all the way to 8000rpm! The supertech valve springs did wonders, those along with the hayabusa style turbo manifold allowed that to happen. Still stock head, valves, cams, intake manifold , throttle body.

oil starvation, do to a piece of debris in feed line.

update: Did my first track event with this much power, I attended Grip Fest which is a time attack. First lap, 3rd gear broke. Our transmissions cannot handle over 300whp doing anything other than drag runs, and daily driving. This was a downer because I drove from 4 hours away to compete , and I didn't think I would be able to make it home ( transmission sounded like ice in a blender ).
Call me crazy, but to put myself in a better mood ...... I decided to make a few runs anyway, skipping 3rd gear. I turned my boost controller off running about 230whp, And posted the 3rd fastest time of the day overall! What an adventure ! On top of that, I was able to make it back to the hotel 70miles away. The next day was the final autocross for the year, a series which I have been competing in for points. I was leading my class for points, but if I didn't compete I would be handing over the lead. So what did I do? I autocrossed my broken car, and secured the class win. My transmission was SO BAD, that it stopped my car from rolling several times as I was driving through the pits. Next mission was to make it back home, 120 miles away........... By some miracle , I made it. Video of the weekend coming soon.

All I can say is , WOW!
So have you decided on what way you're going to with a new transmission? I vote C160. |

My next course of action is to remove to LSD from the broken transmission , hopefully it is ok. I have my original transmission sitting on a shelf, and it is good. The broken one had taller/Yaris gears. I would like to a transmission cooler setup, just like our time attack tC. Basically takes the oil from the drain plug, pumps (elecric pump) oil through cooler , then back through oil squirters tapped into trans casing aimed at each gear.

Now this is quite something. Congratulations! Its a challenge to keep moving in such circumstances.
What gearbox [the one which broke] were you using? C56? I had some issues lately when i had an autocross event. Gear selector cables broke,managed to change them and then radiator started leaking,managed to fix that too [a friend who repairs radiators for a living was around] and then i won :) |

You lucked out I guess, this is the first transmission failure in the life of this car which isn't too bad I guess ( considering ). I grew used to the tall Yaris gears, however now that I have a high rev limit, I may be better off going back to my xA gearing . I am really hoping my Kaaz lsd is ok. Does anyone know detailed info on the Kaaz gearset? Are they stronger? I know the ratios are closer..... but I would want that set more for a strength upgrade.

The C56 transmission from the Vitz RS is quite strong. The same transmission can be found on the Toyota Starlet Glanza [two door starlet with the 4efte]. But they have a limit too,around 300whp max [dont remember the torque figures] and they are known for 3rd synchro failure on high powered set ups.
