Just in case anyone around here is building their own system. I have a complete Air to Water setup for sale.

Ok so I have a 2011 xp900 that I want to turbo. I have turbo many vehicles in the past but the rzr is new to me. I would like low boost for now. 8-10 psi. Now I get how to build everything till I get to the fueling. I see some companies send you a manifold with an injector bung built in. So is there a way to just add bigger injectors and tune them. That’s what we always did with cars. I emailed a few companies but no one will sell me just their fuel setups

Was thinking about pulling my plugs and what curious what the turbo guys were running and please list what RZR model you have as well. Thinking I might need to go to a cooler plug.

Can someone share her PCV setting . Mine is to rich I’m always running in the low 10/1 ratio . Can someone tell me if I can adjust the cold start I find that is running to rich to!! Thank FRED

Up until today My 09 800S has been working perfectly. I have a K&T turbo set to 10# boost. Air fuel is as follows
Idle 12.5
Partial throttle 13.5
WOT 13.5

My problem now is that while riding some woops ad bumpy trails I punched the throttle and the motor fell flat on its face. I let off throttle and it picked back up. So I checked the a/f gauge and pinned it again and the gauge read 17.5 ratio. And now I’m only able to make 3.5# of boost. Waste gate actuator is working properly too I think.

I checked the pure logic controller and nothing seems wrong there. As far as blinking lights to warn me that I need to make a change there were not any.

I looked things over and all seem to be in order as far as no loose wires no blown hoses. The manifold is billet and is in great shape.

And now I have a check engine symbol on the dash gauge. Can anyone give me some advice prior to me taking it to the dealer.

Fuel pressure is at 38 pounds. I took it to 40 and had the same problem so I put it back. Oil level is good.

Maybe the o2 sensor? Suggestions would be great. Thanks Don

I have a built 1110 kit. It’s 13:1 compression on e85. I’m thinking of going with a low boost turbo kit. I know most people will say it’s to much compression. I’m just looking for another 40 hp. Has anyone tried this?

Starting this thread in order to get more info out there on silber turbos for the rzr 1000
Came with under bed intercooler that was unfortunately bent during shipping
However the guys at silber are shipping another one out. So far i have had great customer service experience.

List of the parts in my kit
Kpa gt28 turbo with v band
850 cc injectors
V band mid pipe
Turbo smart waste gate
Head shim (lowers compression)
Optional dual innovate gauge with afr and boost gauge in one
Power comander 5
Silicone hoses
Banjo fittings for the coolant hoses
Intake manifold ( still waiting on that item should arrive on monday)

Here is a picture of the turbo
And some of the items it comes with
Was debating running the head shim or just upgrading the pistons and the rods since the head has to come off anyway.

Eventually i would like to go with an aem infinity ecu and maybe a different blow off valve
Ill take more later tonight

Where are you guys running your oil return line from the turbo to?
The MCX kit uses the engine drain plug with an adapter and banjo washers. I am not a fan. There are 3 plugs just above the oil pan on the left side behind the clutch cover, can they be used or are they pressurized?

Any other locations?

Thanks

Rick

Can I use E 85 in my turbo big block without any mods to engine or fuel system other than a custom fuel map?
Thanks
