MTEG Stadium Truck

Hi gang, I'm restoring Toyota Stadium Truck (PPI-004) over the next 6 months and converting into a Group2 rally truck. Any suggestions on the 152e motor. How does the motor work stroked or should it run as is? Hoping to add some reliability. Thanks, Allen Russell

I grew up watching a VHS tape of these trucks tearing it up and clearing triples.

As I got older, radio-contolled stadium trucks became a major hobby for me. I can't wait to see this truck restored!

contact the member "groupb" on here. he is located in socal. He is your best bet to get more info on the 152E and get you parts for it :tu:

he has one in his RA21 celica

awesome to see a truck like this!

honestly, the only thing to do with the 152E is mail it to me and I will send you a decent 22R. Those 152s are horrible. No torque, even less Hp. In short, they really are just suited for the junkpile, better off looking for a cheap 22RE or even a 22RET...

:lol:

Awesome truck and really looking forward to updates on this thread. Zulu is right, contact GroupB as he can help with just about anything contected to the 152E

hahaha, very tempting

22r would be more reliable, but something about the fun factor of 150hp per liter at 10K rpms. It's amazing what these 25+ year old motors can put out. I just hope I can keep it in one piece.

Thanks guys for the heads up on groupB.

Restoration/Prep starts this week!

This was Ivan Stewart's 1984-1987 factory stadium truck.

It became available after it was racing short course in Canada. I've had it in storage for the past 15+ years. Crazy fun truck to look at and try to figure out. So overly complicated compared to today's racing trucks.

This truck was built before the use of bypass shocks. It was also built in a time period when rising rate suspension was first being used on dirt bikes. Toyota (PPI) use "alot" of rising rate suspension design on this truck.

Front suspension uses tripple rate torsion bars on the lower arms & a single "bump stop" torsion bar on the top arm. All rates are adjustable and many different diameter (rate) torsion bars are available.

Front shocks (3) are lay down cross-over style on front.

The rear suspension of the truck gets really interesting…Cantilever arms on rollers, bump control on shock extension, dual torsion bars. Rear suspension is also "limited" to around 16", but can get much more. Toyota had limited the suspension on the truck to get it to “fly” level.

Rear suspension uses a cantilever front arm that extends (pulls) the shocks on wheel up travel & compresses the shocks on wheel drop (normal rebound). Complete opposite of how most suspensions function. The cantilever arm also uses a torsion bar for the spring.

The rear arms also use torsion bars for an additional spring. As the axle cycles forward, the spring rate is increased at a rising rate as the axle pulls on the arm/linkage forward.

The cantilever arms rest on top of the axle between a set of rollers. As the wheels compress, the roller roll up the arm changing the rate (rising) of the shocks and torsion spring).
