absolutely worth the money! the throttle response is amazing, the car is definitely quicker, and the gas mileage boost was a pleasant surprise- i knew it would go up but by that much? wow.

and i don't have cruise, so it wasn't a steady speed the whole time. aside from the first 85 miles of the trip around 65mph, the rest of the trip was ~80mph interstate. not to mention mashing the gas coming onto the interstate on the on-ramps and showing extreme tailgaters who's boss - so it wasn't perfect speed the whole time - imagine w/ cruise control and old lady style acceleration? perhaps 30mpg is a possibility.

wish I had a 007 oil spray for those tailgaters...

I'll keep an eye on this thread, I'm in debates with myself on this kit for my 914 conversion...since I don't want to cut my firewall for the CIS fuel distributor.

The kit is great. And you can remove all of the CIS garbage and significantly reduce the height of the whole mess. I'm about to switch the CIS intakes to a 3.2 intake, and once i get that done I'll probably sell the converted CIS setup (intake runners with the bungs in place.. But thats a winter project. I highly recommend the bitz kit, but be sure and spend the extra $'s for a wideband O2 sensor... makes tuning the high end much easier. I'll also make a plug for tuner studio... I used it on my mac to do all the tuning and it works wonderful.

+1 on TunerStudio.. Fantastic software

I definitely shoud've sprung the extra $200 ish for the wideband. Im still runing on a barely modified base map, but i just ordered SSIs and an M&K muffler from Ben. Hopefilly i wont break any studs, and hopefully i canget her done in a couple of days. after that I'm going to take it to a guy named Dyno Dan here in Lincoln, who specializes in megasquirt ECU programming.

My advice.. before the dyno a Wideband is an absolute MUST. You;'re going to want to tune at the high end on the dyno and the narrow band is just insufficient to get it right (and I'm of the opinion that seat of the pants is not the right way to do the top)

A wideband is critical for self-tuning and monitoring. If you already have a very close tune, a narrow band is fine but most of us either start with no base tune or have so heavily modified the engine that a standard tune will be too far off.

Well in that case i may as well order the widband now. I'm assuming this is the same one that Tony sells as an add-on to his EFI kit?

Innovate Motor Sports On-Line Store

yes it is

The dyno operator will probably use his own wideband sensor to tune it so you should not need to buy one to get the job done right. If you want to tune later then you will want to get your own.

Definitely get a WBO2 and install. Integrate this with your MS system so that you have a gauge readout in MegaTune or TunerStudio. I have an LC1 permanently installed in the car.

I really like the new Innovate WBO2 sensors where the controller is integrated into a dash gauge. Clean installation and it is nice to have a dash mounted monitor.

I'm interested to get opinions on using Tony's kit on a car that started out as fuel injected but has since been converted to Webers. My car was converted to Webers by the PO. It sounds like Tony's kit is designed to go from CIS to EFI, but it also sounds well thought through and like it would be pretty turn-key if I also used the PMO EFI throttle bodies. Would it be a good choice in my situation?

others have done itb's and 3.2 intakes with the kit.. some of the parts would likely be unused, but he's done such a nice job with it.

Not to take this too much off topic...

Quickstep912. The advantage of Tony's kit is that it is specifically designed to replace CIS.

MS works well with ITBs but you might do better building your own system from scratch rather than have unnecessary parts left over. For example, the fuel rail related components would not be needed with ITBs. Tony could also put together a custom kit that meets your needs.

Consider this... The base tune on Tony's kit will allow your car to start but you would need significant tuning to drive well. The VE table (map) is a very different shape with ITBs compared to common plenum systems. You can really see where the extra efficiency takes over on an ITB setup. equal length tuning is a wonderful thing.

RE: Tuning
 

My 1979 Targa rebuild is still at my mechanics. After the rebuild, we decided on a Bitz EFI kit to replace the CIS. Clean install, but ran into tuning issues. Took it to the dyno, used wide band oxygen sensor, and still cannot get "the hole" in acceleration tuned.

Any ideas what may be causing this?

not sure you mean by "the hole". Are you referring to a dip in power? If so you'll need to adjust timing and a/f in those rpm columns to get rid of it. Also cam and intake manifold mis-matches can cause those dips as well.

muffler in - its gorgeous! definitely a work of art. once the SSI's come in i'll be gettin to work the nearest open weekend i have. any opinions on using a nut breaker on the nuts holding the old exhaust system on? i feel this would offer the greatest ease in removal - and be the least likely to break/pull a stud.

The exhaust manifold nuts can be a pain. They can break the stud. I removed mine by using a mapp gas torch. You heat the nut cherry red and then carefully remove. You may have a whole stud come out of the head if the manifolds have been removed by PO. If you break one, you will find helpful threads with nut welding, special drill fixtures, etc.

Some of the nuts I had were so rusty that they took a undersized socket.

I would definitely use heat and not just soak them if original.

Reinstall and use new hardware and anti seize. You might get away with reusing the barrel nuts.

I bought all new hardware (and extra studs as well), but i thought this might work out a little better than trying to torque the nuts off - basically reducing any risk of pulling/snapping a stud.
