    I’ve been meaning to post this but have not been able to find the the teardown / rebuild pics. My original plan was to build a buggy with the following criteria:


    • Single seat
    • 5:1 weight to HP
    • < 1000#
    • top speed of 55-65 mph (torque over speed)
    • smaller buggy 5’ w x 8’ L as I mostly ride on trails
    • 12-15K budget
    • 2-3 year build timeline


    While “researching” aka, getting prices together, I came across the Redline's and liked the look. Talked with a guy nearby who invited me over to check his out and ended up taking his NA version for a ride in a field behind his house. It reminded me a lot of the odyssey I had 30 years ago, fun as hell to drive. Admittedly, there were a number of design features that I didn’t like, but felt that with some changes, I could make it work. And I could be out riding sooner.

    I found one that had a “Wasteland” turbo conversion (advertised as 130 hp) installed but blown. The owner said he bought it with the turbo kit installed, drove it for 3-4 hours and it seized up, with 70 original miles on it. Something obviously went horribly WRONG somewhere.

    I found the Block was cracked, but the turbo & waste gate were fine. So I picked up a used NA engine and put 9:1 compression pistons, high temp exhaust valves, larger fuel injectors, MAP sensor and FPR. Everything was available from the engine manufacturer as they offered this engine in a turbo version. The turbo engine was used in Polaris FST sleds and Jet skis.

    Got it back together, added a O2 sensor and AEM FIC Piggyback (it needed it). I got frustrated with mapping progress, so I took it to a local tuner and had it set up for 10# boost, using 91 pump gas. Here’s a link to it on you tube.

    Seat time identified that my next steps needed to be 1) Braking 2) CVT 3) suspension.

    Order of mods for a Redline:
    1. Power steering! The effort required to steer one of those is horrid.
    B. Double shear all the heims and rid the car of the junkers that are on it.
    III. Seat change out to a suspension seat or a Sparco
    4. Suspension mods so you can get the HP to the ground.
    e. Braking mods
    VI. Add HP

    Thanks for your feedback / thoughts. Based on you having steering as the first thing, I am assuming you took one for a ride !

    Mine was a bear at first too... I put in a new steering box and spent some time squaring things up. It has made it OK, but could certainly be better. They came with suspension seats. The other items you have listed are pretty much on the mark.

    Thanks again.

    On to the Brakes..I was able to use rear hubs & rotors off a RZR 800 for building the rear outboard brakes. Axle spline was the same. had to come up with a way to support caliper. Found a way on another blog.

    Note: The OEM rims require the 1 " spacer for clearance that is why I'm using them.

    AEM piggy back installation...

    In an effort to put the unit in as dry and safe from flying objects place as possible, it found a home tucked up under the hood at the front of the buggy. I had to add roughly 4' extensions to the wires that I used to tie them into the motor harness. but worth the grief, no issues so far.

    Good start.

    Yes, I’ve driven one. Was blown away with steering effort - the car was a bit ragged so I can see it having been better but not stellar.

    I guess it did have a suspension seat.

    The upper rear links need to be shortened and the mounts moved out so you gain some camber as the suspension cycles so the back end has better cornering traction. We’ll discuss later.

    For comparison. You can see the upper inner pivots Kfab was talking about.

    Yeah, what he said/showed.

    The Revolt has potential to be a bad ass machine but it needs some detailed massaging to bring it out.

    A friend with a Revolt improved the handling, at least in the sand by adding a sway bar in the rear.

    Bullnerd, Thanks for the pictures.

    Kuma, Thanks for the info. curious, your buddy with the revolt, is his name Mike?

    I Picked up a camber / castor gauge to confirm or baseline the current configuration. Below is what I found...


    • Full droop = 1/2 degree positive
    • Ride height = 0
    • full compression = <1 degree negative


    note: The trailing arm's front pivot is angled at 8 degree's. I didn't confirm the toe change.

    Thinking the easiest fix would be to make a "spreader plate" like in the picture below to correct. thoughts?

    Does anyone on here do suspension geometry "on the side" ?
