VZ21 RHB31 Turbo Charger 100HP 13900-62D51 Compatible with Small Engines

These turbos are excellent and small motors. They work very well easy to set up. Keep you oil pressure low and you’ll be fine.

Bad seals from the factory but good turbo if I didn’t get a bad oneUpdate: the company reached out and offered me a full refund without me asking for it. I am very happy with the company being proactive and having good customer service.

Ran the turbo for 1 hour and it worked okay. The max boost is made with it was about 8psi and then it started blowing oil out the exhaust to the point it was not usable

Excellent

Edit: first one arrived bad. I should have noticed the turbine wasn't exactly tight and true. It had a good wobble to it. I didn't think enough to cause no boost. But I will say the replacement arrived quickly and it's pushing 12 psi so far in tests so I say mabye because they are so cheap you'll get a dud here and there but it's worth the shot.I'll come back to perhaps change this review but after spending an ass pile of time fabricating everything for this build, I guess I got a bad turbo. never made boost from the start, Everything professionally done, just see the pictures. and after a short while leaked oil all throughout the intake up to the carb. When the item arrived there was "play" in the turbo shaft, I thought mabye tollerable for a 100$ turbo. But Beware. There mabye good ones, but my first was bad, My second arrives tomorrow, so well see how this one goes. But I suspect I'll be returning that one also.
