a gem of a video to find

Great LS swap content! Reliable and proven setup!!! Giving away all your build secrets for people to save money and start driving!!!

[@dakel7]

This is the perfect fc ls swap video I was looking for 10/10!

[@oldrrocr]

Thanks so much for this video and your comments to questions... I may need it some day.

[@TrustinCain]

thank you so much for this my guy. very detailed and to the point!!

[@addisonclawedeatsalot]

Starting my project on swapping sn LS in my fc this video is helpful thanks

[@jdmsnail2505]

Great video dude, lots of info easy to understand. I'm tempted to swap my r34 RB20 sedan might be cheaper than doing a turbo conversion on my current set up. with more POWA!

[@totoro001]

Love the video! Just as a little bit of info (that may have changed since you created the video). The Holly Terminator X, brand new with harness, display, and ECU, is ~$1100. You mentioned your ECU/tuning solution was ~$400 and your harness was ~$600. That being said, the Holly Terminator X is roughly the same cost. Not 'correcting you' or anything, just wanting to let folks know there is another option that is roughly the same cost, but is slightly easier to use (for those who aren't adept at tuning).

[@johnleedom5606]

Absolutely, thanks for sharing this information. I might be doing a extra cheap swap in a future build. I’ll have to keep this in mind

[@helghit]

Good stuff man. Currently have my LM7 pulled out for a rebuild on my FC. Ended up doing a cam swap with dual springs, trunions, etc. Much like you I used the AR5 trans instead of a T56/CD009 for cost efficiency and it seems to work pretty well. I wish I would’ve done a Z32 trans now when you mention the whole slave issue. Your tip about the headers is a god send to a lot of guys too I ended up buying the expensive Cxracing ls swap headers and am kicking myself for not trying to use a cheaper shorty setup.

[@operatorblack]

Decent video, I learned a lot. This process has been streamlined a lot since people first started doing it when these engines first hit the market. Really nice to see the nissan transmissions becoming popular swaps because they are really decent for these types of applications. I used to have a high powered built and boosted Toyota 86 and doing the CD009 trans swap made all the difference. I'm looking to do an older japanese coupe with a 5.3 or 6.0, and your setup is very inspiring. Thanks for making this video and reading my long ass comment hahahahaha

[@patrickstarr87]

Awesome video 🤙🏻

[@deangelowoodside5159]

This is the cleanest ls swap I have seen yet this is amazing I am considering doing a ls swap on my 1984 z31 and I will definitely follow this pattern nice work keep it up

[@sumosami]

well if it's na your gearbox can hold for 400-500hp but i'm not sure if toque will be problem. go with turbo gearbox

[@holdinrossing2010]

Hows the z31 swap going?

[@ascension6142]

Sick build

[@p66ter]

Awesome content man ! Thank you. One question though how far off is the shifter location with the z32 trans and your mounting set up?

[@GDFGC8Owner]

Awesome info man👍🏾 what is the part # on the front radiator and fan you used?

[@qwerty28637]

This build has been a huge inspiration for mine! I'll also be running a z32 trans paired to an lm7 with the ronin mount kit. I'm curious if you had to remove the stock trans mount humps in the tunnel like the instructions from ronin say?

[@johnleedom5606]

It’s been so long since I did it but I don’t remember cutting anything off. When you use the ronin kit with the z32 trans, it mounts in a slightly different position

[@justinsantiago5030]

For your trans , are you running the twin turbo or na , I also got a z32 trans granted I paid much more , and that adapter plate is about 800 now

[@BloodMoneyRacing]

Will these engine mounts work in a FB

[@coltenfike4272]

What did you end up doing for the master cylinder and the lines for it?

[@johnleedom5606]

Stock master. the line I made myself, but if you know the length you need you can have a brake line shop make it $50-60 roughly

[@dogbitebbq3134]

How do you like the z32 gearing matched to the na diff?

[@johnleedom5606]

1st feels a little short but other than that it’s good. I think the t56/CD009/z32 trans have very similar 1-5 gear ratios

[@codyfryers]

Did you use the factory na driveline? How much of the factory mazda wiring did you cut out? The trans you used, was it from a tt z32 or a na, or does it matter.

[@johnleedom5606]

I had a custom driveline made. All the OEM harness is gone. Trans is from a NA Z32

[@codyfryers]

@@johnleedom5606 do you have anything for your exterior lighting or is it purely a racecar only? Thanks for the reply!

[@prestonlouallen599]

@@codyfryers I’m curious of this as well. My 240 has no harness so I’m wondering how it works.

[@MrWyza1]

Are you using the stock oil pick up or the moroso pick up?

[@johnleedom5606]

I believe I’m using the stock pick up

[@dogbitebbq3134]

Was the z32 shifter location close to the stock placement?

[@johnleedom5606]

With a transmission shifter adapter it sits closer to the stock position but still some trimming is required

[@timothydelacruz8206]

Where r u from very we’ll built

[@THEBOILEDONE]

Does the harness you purchased hook to the Silverado ecu? Is there two??

[@johnleedom5606]

Hooks to the truck ecu (Silverado/Yukon) and there’s only one ecu

[@THEBOILEDONE]

Thanks man I just looked and seen two big plugs on the purchase link.im working on swapping a 1987 fc.i did the manual swap some years ago and finally drug her out of the woods after watching all these LS builds on KZbin

[@johnleedom5606]

@@THEBOILEDONE yeah just make sure you get the right wiring harness for your Ecu. Red/blue plugs are drive by cable (mechanical throttle body). Blue/green is drive by wire (electric controlled TB). The plug ports on the ECU are labeled, so it’s easy to figure it out

[@THEBOILEDONE]

Could I use my stock harness for a carbureted 350?

[@mikehubbered9799]

What did you do for drive shaft

[@johnleedom5606]

Custom made. Any driveline shop will make it for you, if you know the diff & transmission. Call ahead of time to make sure you measure it correctly. Every shop has their preferred method of measuring the driveline length

[@mattlebert4206]

What did you do for a driveshaft?

[@johnleedom5606]

I had a local driveshaft shop make it. If you measure 📏 it they should be able to make it. They need to know what rear end and transmission you are using so they can get you the right yoke & flange

[@omarexxikouri17]

What type of clutch did you use ?

[@johnleedom5606]

Z32 clutch

[@clarkinthedark1]

$200 motor.. good grief that’s great! Here in CA they’re $700+

[@dragonbond5609]

so how did u get the harness to convert to the chassis?

[@johnleedom5606]

I did it as standalone systems. So the chassis harness and engine harness are separate from each other.

[@dragonbond5609]

@@johnleedom5606 oh nice thanks for awnsering

You are leaving so much on the table I not having a good cam

[@Schlipperschlopper]

Sadly soon all combustion cars, bikes including classics will be banned from public streets in entire EU and Scandinavia :-( In Germany the Green Peoples Party gave order to shorten fuel supply from 2025 on by reducing all conventional fuel stations to only one state operated central gas station per city or county. Now they want to slow down all the gas station pumps from 20 litre per minute to 2 litre per minute...From 2027 on in the EU certain car spare parts will be banned too....as exhaust systems, turbo chargers and even some engine and gearbox oils...California and New York will do the same from 2027 on.... So no investments should be done in oil burning cars any longer....They even created a new kind of crime here, called emissions and smoke crime (BABVVO=Bundesabgasbespassungsverbotsverordnung)!!!
