View Full Version : ST2 LT Build & Questions

I'm building the ST2 LT, but I have a few questions.

1) The plans recomend U-Joints, but I see a lot of people doing CVs. Are the CVs really that much of an upgrade over U-joints or is it just easier since most car axles already have the CV.

2) The plans say to press the rear wheel bearings into the carriers, and later press the hubs into the bearings. It seems like this would put unnecessary stress on the bearing because this would leave the inner race unnsupported, if that makes sense. I have been told that this will ruin a bearing. Is this the proper way to do it or am I missing something?

Im sure this is common knowledge to someone I just cant figure it out.

One thing I wish I had done was modify the cage for more head room. A little more length in the engine compartment would have been good too. That frame looks nice, well done. What kind of motor you runnin'?

I think u-joints can handle a lot of power but the ones they have in the plans seem kinda light duty.

Yeah, my build's in the ST2 forum. I'm just waiting on powder coat right now. I used a TL1000R motor.

Classic Iron,
Have a lot at John's thread

Page 3 and 4 I posted some pictures of one of my ST2's with an R1 engine in it.

Good luck,
Ted

Ted,

I like your buggy with the r1 in it. Is your frame built to the plans specs or did you modify it?

Edit: Nevermind I read the rest of that thread. That thing about the A and B pillars is good to know.


Sotiris,

ive read through your thread more than one time, it has been very helpful!

Welcome to the green side!LOL If ya mod the exhaust, and 99% time ya do, I got engineer at Bazzaz to program their fuel inj control and wideband o2 for her. Really smoothes out the throttle. Several other mods to help performance. I'm doing a turbo now, on e85. Should be fun.

UPDATE

Seat and harness installed.
Steering system complete
Front suspension complete
Front brakes installed.
My engine is partly mounted, and it starts up and runs nicely.

I'm about to start work on the pedal assembly and shifter. The engine doesn't have a hydraulic clutch, so it will be pretty simple to fab up pedals. I was originally going to use push-pull cable to connect the clutch pedal to the engine, but I think it will be cheaper to make a mechanical linkage out of 1/2'' tubing. I will probably do the same with the shifter and throttle.

Zx12 didn't come with an airbox, so I will have to custom fab that somehow.

I just ordered all my dashboard switches. (all waterproof so I can hose down the cockpit after a muddy ride)

Next I have to lengthen the chassis by about 4 inches because I didn't want the engine to be above the rear axle, so the rear axle has to be pushed back.


Unfortunately my drill press motor bit the dust so work is at a standstill until I sort that out.

K & n e-2900. 75 nissan 260

This is what I found. Made upper and lower plates from alum. Drilled for intake boots. There are a few that sell the setup. I may sell mine since I’m doing turbo, not sure how I’m going to build plenum
