Anyone running the TBI conversion for 4.2s from Performance Fuel Injection Systems?

It seems to be a more complete system than other aftermarket TBI systems with the inclusion of the HEI and it is several hundred dollars cheaper than other kits that dont have the HEI distributor included. I've been thinking about a MC2100/HEI conversion, but that would be halfway to this kit. I dont find much about them, but they have great feedback on ebay and a TBI system is barely more complicated than a carb.

I've never heard of them. The pictures look good, and it appears to be complete. I did some quick searching and wasn't able to find any reviews or posts about people running it.

There are a couple of other companies out there making similar kits. If you're not in CA they probably all work about the same.

I'd buy it if I had a 258. It ain't rocket science. They obviously have a source for old chevy TBI parts. (Probably local junkyards) They go through them, clean and test the injectors, (they also run an injector cleaning and testing service) test the ecm, put together an ignition and there you have a kit.
Nice to see they aren't trying to get rich off of every sale. The Chevy TBI is reliable, simple and replacement parts are plentiful.

Do a detailed write up and evaluation.

He has a walkthrough for the 350 kit and it looks like a complete kit.

I've owned this stock 1989 YJ with 71k miles since new and am finally ready to upgrade it. I've bought and sold a lot of other jeeps over the years, but never messed with this one. I am not going to spend another minute rebuilding and cleaning the carter carb.

If the smog laws here in CA change like they're saying, I'll probably get his 350 kit for my little motor home.

They are pretty responsive if you have questions. I asked how their kit would work with my HEI and they answered back in less than an hour. I guess I'm going to have to start saving for a fuel injection kit.
I can't let momma know how much I spend on the rig or she will want to spend equal on shoes or some other really useless stuff

What's the skinny on smog law changes?

Whatever it is, way over due IMO.

I'm going to order the system in a few weeks. They've answered a lot of my annoying questions, but I was checking to see what the gear on the HEI unit was made of due to some HEI gears eating the cam gears.
