Hey guys I’m back it’s been a minute! The time has come to release a full turbo kit. This will be available to purchase on our website 4Nmotorsport.com in the next two weeks. I have now pushed this tractor over 350hours with the turbo and it’s Making an estimated 40-45hp with no issues. I will...

Sorry guys still using the tractor like crazy 😂 thanks for patiently waiting. Pto Dyno is like 2 hours from me so gonna load her up next week and get on it. Otherwise it’s still taking a beating.

Throwing it on the pto dyno next week🤘

Hey Guys! I am still here. To be honest I like to test everything I make so that’s what I’ve been doing. Let’s just say it has now had over 100hrs of brutal testing with my turbo setup running 10-12 psi boost and no issues at all. I ended up bumping my hydraulic pressure up 500psi as well since...

Hey so to answer your question after researching both engines Kubota simply pulled the timing down to 5 degrees btdc. They also lowered the max fueling of the injection pump to meet tier4 requirements. Simply bumping the timing up on the d1703 and adding fuel will get you slightly over 30hp...

Diesels do not use blow off valves there is no throttle body like a gasoline engine. Typically on a gas engine when decelerating the blow off valve diverts excess boost away from the throttle body while closing. The wastegate on a diesel is used to control boost. I am running the factory setting...

That’s awesome man!!! I purchased this tractor 6 months ago with plans to do this I really didn’t want the dpf and the price difference was crazy going up to 50hp. I did a lot of groundwork and even asked the Kubota mechanics at the dealer when I picked up the tractor if it shares the same pto...

Thanks for the heads up! The pcv was the first thing I did since it will cause a massive boost leak the way it’s routed into the intake manifold. Also on all my turbo cars/trucks I re route the pcv to atmosphere. On the Kubota I just ran a new line down next to the block by the pan basically the...

Hey man! Attached below are the kits I normally build. It’s mainly a hobby/passion that turned into a business for me but I enjoy fabrication. I currently produce turbo kits for the bmw n54 335i and s55 M platforms check out our website 4NMotorsport.com. This kit on my tractor was pieced...

link to a sound clip!!!

No problem I will make a guide on the changes I made and the power expected. Also major update!!!!! I just finished installed a MHI tdo3 7G turbo. This is the same setup on the v2003t Kubota engine. It spools beautifully and this tractor is making at least double the hp. It literally flies up...

Hey! Yes an rpm adjustment will make more hp but you will loose tq drastically especially above 2500. The only way to raise the peak torque in the power band is to add timing. Let’s say the engine in its stock form makes peak torque at 5 degrees of timing at 1650rpms which I believe is around...

Hey Guys new to this forum. I own a performance shop and I build turbo kits. I started in the diesel world with a 4bt swapped 47 Chevy currently making 600whp 950 tq on 70 psi. I also build custom turbo kits for bmw platforms. I purchased 5 acres of property and jumped on buying an l2501 HST...
