Holley Terminator X on a Gen2 LT1

[@Drew-kb5px]

For the crank sensor, if you’re already buying the shielded cable from Holley, part 570-223 is the correct connector for the Torqhead crank sensor.

Great Video. Just sold my Turbo lsx foxbody with a Termi X Max and picked up a clean 95lt1 t56 corvette. Want to Termi and turbo it now for my next project. Perfect video to find. Subscribed

[@masyningles8667]

Definitely an underrated build

[@xxnutty1xxnutty120]

Awesome video!! Very informative!! Definitely going the same route you did with the torqhead signal kit!! Can’t wait to get it in this spring! Thanks

[@coderedcamaro4812]

Thank you so much for this video!!! I'm going to be doing this on my 97 trans am.

[@r3d-1truth17]

Hey Mike- thanks for your video and education about this project. I’ve watched this video several times and in the process of converting my LT1 to this setup. I hope you would be open to answering some questions and sharing your thoughts and experiences with me once I crack this egg open. Nice ride, I look forward to seeing your posts. Cheers

[@michaelbauermeister348]

Appreciate the video. Looking at this set up on my 94 vette. Want to build a 396 or 383 for it.

Appreciate you for making this video !

Mike what fuel pressure regulator you running is it stock

[@nitrousfedfilms5597]

Thank you. Thank you. Thank you!

[@JPack48]

What did you do for knock sensors? Also, from everything I have seen regarding the kit, there is only the standard LS firing order as an option. You said you changed to correct one. How did you do that if there appears to not be an option to do so?

[@dirtymikesgarage9053]

I’m not running knock sensors. But if you choose to, you can run LS knock sensors. Terminator DOES offer more than one firing order. You can actually even make a custom firing order if needed. Most terminator x computers need the latest software version to be installed and then will show you all of the firing orders available on the handheld

[@Savineyard3]

If you ever redo another LT1 engine build for the supra using the Terminator X system, You can do the 4-7 cam swap and Holley's X system can run it.

[@dirtymikesgarage9053]

I don't see a point in doing the swap since the Holley will run whatever firing order you want to run.

[@Savineyard3]

@@dirtymikesgarage9053 Yeah I looked more into the 4-7 swap and I see that most Small Block Chevy's won't see any improvement.

[@DeuceDropper7]

Great build and great information on this! What are the specs on your cam? If you are not willing to share.... can you just share how much overlap at .050 your cam has?

[@dirtymikesgarage9053]

The cam I had in this video was a complete cam 306. The new engine has a Tick Turbo cam

[@Mpreston89]

Great info! Thank you.

[@IssaR6]

I have a question on how you mounted your coils. I really like how they are bolted to the factory valve covers, im wondering what bracket you used and how it bolted on?

[@dirtymikesgarage9053]

That was temporary as I went with different headers that didn’t allow that anymore. I just used factory coil brackets and made some spacers and mounted them using the LT1 valve cover bolts

[@IssaR6]

@@dirtymikesgarage9053 Thanks man, much appreciated.

[@mavsformulaful]

Im guessing you could use late model vortec 350 ignition? Use the 96/7 cover and then machine the manifold for a vortec distributor.

[@Thelostsounds28]

I’ve been trying to make my 96 lt1 run right and it’s been nothing but problems a few buddies said I should do this is it pretty easy? How long did it take to do it all?

[@dirtymikesgarage9053]

It took a day to install the system and have it running

[@richardgraeser7196]

Thanks, Very good info. Could you share how you are running the cooling system?

[@dirtymikesgarage9053]

Richard Graeser I’m not sure what you mean? It has a supra radiator with upper and lower hoses. Everything else is setup just like a stock LT pretty much

[@HellTriX]

With the 1994 timing cover and a cam sensor, is that all that's needed to get cam signal on the 1993 LT1? Like is the internal part ready to just add a cam sensor?

[@jarmaljackson7455]

Very nice!

[@fun-fun2164]

I have a 86 Toyota Supra how would I wire it it straight in from the engine to the computer brain how's the car

[@dirtymikesgarage9053]

You might want to do some research on Holley terminator. Holley comes with its own harness and computer

[@courtneysmith8706]

Do you have to use the terminator x box or can you use another Holley computer

[@sillyguy9828]

Im doing a fox body and i have a 94 lt1 im going to put in it. I want the exact same set up you got. A suggestion?

[@johnchristie7098]

Hey Mike, I did the same conversion that you did using the torq head signal kit and running the Holley terminator x max with dbw, did you have a problem with you timing being off by 19 degrees? I pinned it like you showed but I had to pull 19 degrees out just for it to be at zero.

[@dirtymikesgarage9053]

I honestly don’t remember right off hand if we had to do any correction. I had a little help setting up the tune as I was fairly new to Holley at the time.

[@natedearth]

im looking at doing the efi connection kit that includes the 24x conversion on my 96 lt1 engine, did you have any problems with the limited 4 inputs and 4 outputs the regular x has? particularly when boosting it and when running gauges as well? dont wanna buy and then figure out i cant run a aftermarket speedo and tach and all the other gauges in my swap. going with a dbc setup.

[@courtneysmith8706]

Can the setup work with a 4L60E transmission?

[@courtneysmith8706]

How would hood-up a 3 bar MAP to the Holley

[@boydbeckner7175]

Did you have any issues with timing? I did this setup with terminator x and I checked static timing and it is 15 degrees off. Just wondering if you changed it.

[@dirtymikesgarage9053]

There's no distributor so how can you get the timing off? Its all electronic. I didn't have any issues. How did you check the timing?

[@boydbeckner7175]

I found top dead center using a piston stop, set up static timing to 15 degrees in terminator x software and then checked it with a timing light. Timing light read zero. Then I turned the static timing up to 30 degrees timing light read 15 degrees.

[@dirtymikesgarage9053]

@@boydbeckner7175 I'm not sure what to tell you. There's no timing marks on the LT1 so I'm not even 100% how you checked it with a timing light? What signal kit are you using?

[@boydbeckner7175]

It's got an aftermarket balancer with timing marks and I'm using Torquehead signal kit.

@@boydbeckner7175 hey boyd, I know this is a old post but I ran into the same problem with the timing being off, did you ever find out what the problem was?

[@reyracer]

I have no spark, switched the wires on the crank sensor and still no spark. Can anyone help.

[@boduke2299]

Why not just put the entire torque head kit on it wouldn't it be easier, or is there an advantage to having the holley setup?

Hey can u tell me the part number and who makes the forward facing headers

What Headers did you use? Looks like C4 LT1 Corvette headers from the top unless there Impala SS Headers.

[@dirtymikesgarage9053]

They are neither. They are SBC block huggers

[@doomsgarage]

So when you say gen 2 lt1 you mean from the 90's not the early 70's right?

[@dirtymikesgarage9053]

Correct

[@Bro_dee007]

I haven’t seen any videos about the modified intake you have on there; (maybe i overlooked it) but it looks like a standard 4 bolt ls throttle body on the lt intake is that a custom piece you made yourself? Would be nice if you would go over that if you ever get the time or interest to do so.

[@tunerdadtunerdad7927]

I believe he just cut the stock one and did some welding. Simple piece to make really, and a great idea.

[@dirtymikesgarage9053]

到處尤伯杯 it’s pretty straight forward. Just cut the front nose off of the stock intake and welded on a LS flange

[@jmerica4818]

Why even bother when you can get a twin 58mm for the stock intake. Little grinding to enlarge the intake holes and you have plenty for boost or whatever.

[@cheezyrider1111]

Is that a suprette? Or a supmaro?

[@samshaw4851]

Does holly delete the maf sensor?? I have so many questions. Lol. I have a stock gen 2 set up. I’m doing turbo set up. I’m not going to really BOOST it. Will stock ecu with maf sensor run it ??I worry about map sensor going nuts.

[@dirtymikesgarage9053]

Yes it runs off of the map sensor. So no maf needed

[@chriswescott7242]

Question I got on this is, how can I still run my a/c with this! My lt1 trans am is mostly stock just a bolt on car and I’m tired of the opti! Coil! And icm!!!

[@dirtymikesgarage9053]

I'm assuming you would just have to run power to your compressor. The Holley has a a/c input to adjust idle

[@michaelduffy3871]

I have the same set up, did you have issues with crank sensor air gap??

No sir I didn’t
