Nice little rig! I would definitely adjust the rack limit stop to give more fuel and like Kubotaman said, put a stiffer gov spring in. Then you will have the power you need, that thing can't weigh much. Nice MPG #'s. You should be seeing more boost #'s as well, maybe tighten the wastegate some, I see 20's + a lot.

 

The waste gate servo has been eliminated. It runs so much better on cool mornings and if it ran that well all the time, I would be completely satisfied for what I'm after. I am hoping that the intercooler will get me where I want to be. Its kind of like driving a 40 hp volkswagen beetle. You can rag on it but its best to chill and enjoy the ride.

about the weight, it has a full frame even the tops of the McPherson front struts are frame mounted. Its weight is deceiving I would guess about 2200 striped down like it is. no AC,carpet, back seats and just a bikini top.

 

I like your conversion. Are you still at stock fuel on the pump? What sort of EGT does it put down. you might have some oomph left in that engine. Have you tried any other turbochargers? I hate to say it, but I am on my 3rd turbo, small, smaller and smaller still, and I think I still might have a tiny bit too much turbo. I finally went overseas for my latest turbo, You might be able to look for something similar to this, or even smaller.

I went with a used OE turbo and it was even cheaper plus it is not a china clone

I think you are doing great with under 1000cc's displacement?
have fun

 

Mike great to hear back from you! I picked up a sidekick the other day, a 93 4 door 4wd. It's got an automatic which I'll be swapping for a manual but the frame is clean and for $200 with title I couldn't go wrong. Drove it on the trailer then 20 minutes back home. I already have the Kubota. So I have 4.62 gears. Body is completely coming off. I'm building a utv. Current plan is to run 29x10.50 super swamper sx's. They're a bit heavy but I'm not going for speed or economy. With estimated output after turbo of around 40hp and 80-ish lb/ft torque, it should get around well enough. I want to be able to drive on the road occasionally but if I can't get over 45 mph that's fine with me. Just be on back roads mostly. I'd like as much detail as you can give me about the trans adapter and clutch setup. You can email me bigblue12v@gmail.com if you'd like. Thanks so much!

Which flywheel housing did your kubota have on it? Was it an SAE# housing? I have a v2203 that has an SAE flywheel housing that I am wanting to put into a tracker.
