Hey, can i fit a TRX 2.5 or an M16 in an overdrive ST. If Not what are some other cheap but good engines I can fit,

Thanks

What size engine is in the Overdrive ST? The 2.5 is a .15 engine. I would think it would fit. I asked tech support for the Sirio .18 and asked about what other cars I could put it in, they emailed me back saying they use a .12 case. So I fits in any car that takes a .12 - .15.

Hope that helps.

It has a velocity 17 that always dies and never runs right. And it's tuned good.
