Boosted Performance single turbo build

Boosted Performance

UPDATE:


James (customer/owner) came by last night and got the car out on the road. After a short drive everything seemd good, even the base map was very good. He parked the car for 30 minutes, and came back to start it up and go for another quick spin. Shortly after strarting he noticed smoke out the back (exhaust)....after a couple of texts we agreed that it was best to come back this morning for me to go over everything...ensuring him that it is not a big deal....(don't think he bought any of it though :lol


I got the car on the lift, and noticed a bit of oil resedue coming out of the turbine housing...both sides. I made sure that the pump was working, and dwawing good vaccum, so that was not the issue. This confirmed that the turbo seals could not have possibly blown, and everythig else looked very good.

When I installed the oil feed line, I did not install a check valve at the turbo oil inlet as I do with the 350z kits. Reason behind that is that the oil line feeding the turbo with this kit is very short, and even if it was to completely drain, it was not going to be enough oil to fill the small reservoir I use at the turbo drain. I was wrong...it seems that there is still pressure left in the system after shut down, and that the path of least resistance is taken by the oil to relieve this pressure. It turns out that the path of least resistance is the turbo. So after he shut the car down, the oil reservoir filled up, as did the turbo. With the oil sitting in the center section some leaked past the seals and in to the turbine housing/exhaust. When he went to run the car, this oil started to burn up causing the smoke. No harm done...just a bit of oil going past the turbo seals.

I installed a check valve this morning, and we went out for a spin....all is perfect. No smoke (after it all burnt up from yesterdays leak) and the car pulls great, sounds amazing, and sure puts a smile on the drivers face. We did a few WOT pulls so the logs can be sent out for analysis, and we shall go on from there. I must admit that the turbo combo with the F.I exhaust is just perfect, quieter than on a stock block, making this car the perfect sleeper.

The car will get some miles on it now, and come back for another visual inspection. If all is good, this was a complete success, and I will proceed with making the jigs for this kit. This will take a bit of time as the jigs will be complex, and take time to build just right.


I would really like to thank Vince at R/T tuning for coming through with the base map...I can't believe how good it is considering he has never seen this kit. I would highly recommend him and his services to anybody. He really is the UpRev guru.
