View Full Version : My 3.3 is 6 gallons old should I just power up for 100 or spend 200 new motor?

It is about time for me to swap or get a new different engine for my Slayer Pro. I am not sure what to do should I just swap for new 3.3 for $100 or buy new motor like OFNA/PICCO .26 for Revo for $200. I do race my Slayer in the local club points race series, but I run in open SCT and I am the only nitro in class. I am currently 4 in points and the guys let me run with the elec. SCT so I don't want to be much faster because they might throw me out of class if I have a really fast motor. Anyway what should I do or what would you do my idle is not very stable up and down and my low end is getting weak thats why I want to get new motor. Thanks for any advice!

Personally, I would just throw down $50 and rebuild with a new piston and sleeve. As long as the rest of the engine is good. I feel that the TRX 3.3 delivers plenty of power for the Slayer Pro platform.

With 6 gallons of use, it is best to replace the rod and bearings too. Now you are near the cost of a new engine but still have a used carb and such.
Buy a new engine on eBay and keep the old one for parts. Or part it out.

Well I just got back from track practice for tomorows GCS race and my Slayer was running great only 2 seconds behind Truggy times. And it happened the motor just lost all power and shut off I came home and took it apart the connecting rod split down the middle so I am screwed for tomorrow the LHS doesn't open until 10 am and thats when racing starts. I'll just be able to run 2wd SCT with my SC10 no open 4wd for me sucks! I am just going to trade my 3.3 and $100 for new one. The bearings are probally gone and I would rather just drop in new now that there is probaly more damage from blowing up. Thanks for input!

Yeah I know if I had changed piston and sleeve when you recommened I would have been able to get away with it but now that it broke I went ahead a got a new engine yesterday. I had a heck of I time breaking in new motor properly I couldn't get it to idle without leaning out to the point of poor lubrication ever time I pulled throttle it seemed to load up on fuel and choke. I finally got it broke in I guess and started tuning with the help from a couple Pro Bugggy drivers and they even had a hard time tunning and gave up. I did too for awhile then after A-Mains I to it to the track and finally the truck seemed to smooth out and I was able to get a decent tune very weird almost like to low speed needle was stuck open cause there was a ton of fuel coming out header. I hope alll the up and down tunning hasn't hurt the amount of runs I will get out of this motor before rebuild. What a pain in butt have you guys had a hard time tunning your new 3.3? Thanks Again!

New 3.3s are 90-120 bucks on fleabay. I'd keep the old one for a good carb, crank, head, and block.
