Hey guys, I've been contemplating turbo charging my 331 for a while. No, its not a dart block and, yes, I know its only good for 500hp under 6k rpm. The question I have is does anyone have hands on experience with on3. I plan on running less than 6psi making no more than the block can hold. I do have a balanced assembly and a block girdle installed. ( just to keep the crank together when and if it cracks ). They have a fuel system kit for about $1000 w/dual 340lph pumps. With the upgrade to ceramic ball bearing turbo, 60lb injectors, and MAF ran the total to about $2500 w/o fuel system. Is there anyone here that can offer advise on this set up ? I've already dumped over 6 grand in a 302 block (stupid) HCI stroker kit, at least its a Mexican block. smh
 
I've Hurd horror story's about on3 in the last 6-8 months.. Not shipping all the parts you pay for in the kit, taking 2.5 months for it to be shipped out and then not receiving all parts. Customer service and support team sucks. . The turbo kit it's self is flawless but just be prepared for a high blood pressure check up at the family doc office if your part fails or is missing pieces

This is almost all true with the exception of the kit being flawless. I bought a kit from them, it was a disaster. Run away.
 
Reviews are so mixed...a bunch of people love the kit and the service, but I did see some crappy recent reviews. Thanks Boosted92LX, mikestang63, and Lscam580. Is there a reasonably priced kit that either of you can recommend ? Is there anyone else that can chime in on this. Not trying to spend a fortune, but expecting to drop a few grand.
 
I saw a vendor over on the corral who was selling an upgraded on3 kit with a precision turbo and tial wastegate etc for around 2500$. I don't have a link but you could check there:shrug:
