EFI Conversion On 1997 57GL - TBI/MPI/TPI With Or Without Vortec Head Upgrade

[ijsaul]

While not marine, it does look like a pretty cool kit, and it's interesting that those more DIY ones are on the market now.

Unless the tune was spot on for your heads/octane/etc., you'll need a way to tune it.

I, in the end, went with a brand new Holley marine unit, a new intake manifold, and a super hot coil. This solved all cold start/restart issues, and has been very enjoyable for not much spent.

Need a marine kit. Besides the safety issue, the fuel curves are completely different not to mention the fact that this one has an O2 sensor which you are not going to be able to use.

Read through this thread as I am considering converting my 1994 Century 5.7 260hp 2bbl carb to tbi. I am thinking simple and I'm not wanting to spend a fortune. My boat runs good enough, but starts and idle are not always the greatest. I'm wanting the perfect starts and idles. I am sure other men can relate, but my wife can't operate the boat unless it's starting and idling good and that can be a pain for multiple reasons. I have several pre vortec parts from a 1990 chevy for the tbi conversion but I'll need to pickup a few parts. I found this on ebay:

and they'll take out the parts I already have and reduce the price of the kit. I thought I'd get a marine tbi distributor instead of the one offered in the kit. The other concern I have is mounting the ecu, map, etc. How and where is what I'm wondering. Would I need to buy a tuning program to hook to my laptop? I'm not wanting to get real deep here, just better start, idle, and maybe fuel economy.

Bad ideal ..if your well versed in Fi start a thread.
