All the power of a bigger turbo without the big turbo lag.
Been think about it for a long time, but I think it should work half decent. I currently have a 17/22 which is pretty much at its limit with egts getting close to 1500-1600 while at wot in 4th. A hy35 feel into my hands so I'm going to put it to good use.
My plan is to leave the 17/22 as it is but with a external wastegate on the egr port set to ~15psi and dump it into the down pipe. I will cut the down pipe from the 17/22 and cut bend and weld a new pipe to the battery box area on top of the trans. The battery has to be moved to the trunk which will give me some space to mount the hy35. Weld a bung on the oil pan for the turbo drain, route some ic pipe from the hy35 to the 17/22 which is pretty much already there, and all the little things in between.
I'm not sure what kind of boost will be possible and efficient with this setup. The wastegate on the hy35 is seized solid so another external gate will have to be used if necessary, I'm not sure how much psi it will hit with it closed. In theory it should drive as nice as it does now around town but with more grunt up top.
I already got most of the parts and this is a budget build, all said and done I'm in around $500
Looking for any thoughts, suggestions, experiences
