TFI Upgrade

Anyone have any feedback on the TFI upgrade?

My 4.2 starts great but idles rough, loses power around 3 to 4k RPMs and the exhaust flat out stinks. Is this kit really worth the money and trouble?

My stock Distributor Cap sits pretty close to the block and oil stick. Is there a space issue?

Also, does the new coil mount where the stock one sits?

Thanks...

Probably one of the best mods I did to my 84 CJ.
Parts are relatively cheap and easy to find at any auto parts store.

The new coil can dangle off of the stock coil clip if you want. Others wire tie it to the battery tray or fabricate a mount on the fender.

Here's my writeup if you're interested.

The symptom of stinky exhaust tells me you have more than ignition problems, so don't expect TFI to solve everything. It will help, but me thinks you need some carburetor work as well.

Does anyone really run a 4.2 at 4k rpms? I don't even run my 4 cyl TJ like that...

I don't always run it past 4K but it is nice to be able to. The TFI is well worth the cost.

1986 CJ7, 4.2 w/4.0 head, TFI-HEI hybrid ignition, Clifford manifold w/Holley 390 w/cold air intake, OBA, 4.5" lift, Woody CV shaft and Tattons in front, 4.10 gears - lunchbox in front, Truetrac in the back, twin-sticked, blower upgrade for running topless, trying to keep it simple.

It's just a Jeep, and if you don't wheel it once in a while, it's not even that.
