lt1 24x ls conversion

Unfortunately I'm a cheapass, with a matching budget LOL.
Even if I could/did find a cover @ a price I was okay with, the machining of the hub would still also add to the total cost.

Machine shops around here aren't cheap, and even small jobs are sometimes ridiculous in price.
I honestly think they give a stupid $ quote sometimes, because they just don't want to do the job.
Some won't even do small jobs, and understandably it just isn't worth it to them.
Like when I asked a local shop to weld a pair of AN fittings on an oil cooler line flange....$40/ea. was the reply
Yet all their guys are standing around with their thumb up their ass in shop...
I went to a local AC shop, and they charged me $10 for both, and it was done in like 10 minutes.

Most of the local small machine/speed shops that once existed, are long gone. Used to be a couple real good ones here, but
no longer the case.

That is exactly why they do it. It is hard to make money doing a small job like that when the amount they charge you won't even cover the hourly wage of the employee doing the work. So they have to charge a large amount to make it worth their while.
I have been on both sides of this. It sucks when you need a small quick job done but no one wants to do it. But also back when me and my brother in law used to do commercial lawn service, there were people that lived way out in the boonies wanting their lawn cut. But it was 30-45 min drive or more just to get to them. It was not worth the fuel, employee hourly wage, and time to drive all the way out there to charge a normal fee. We had to price the job higher to make it profitable, we could not afford to lose money. Some customers would pay it because no one else would come and do it. Others would not.

You might check around in your area to see if there are any hobby machinists out there who might help you out. You might try putting up a ad on craigslist.

I installed the EFI Connection machined cover and 24X reluctor on my gen1 TPI. Big $$ but clean install. A little competition doesn't hurt. Now looking for a harness.

Well there are now 2 '96 b-bodies @ a yard 60 miles from me.Figures...no time to go now. With any luck maybe I can still score a cover after Christmas?

Well, 'bit the bullet and ordered an EFIConnection LT1 24x kit today.
Banking on being able to get a cheap '96-'97 cover and hub from the JY. Going to head down probably Friday, and hopefully one will be available still?

I have a complete donor harness/coils/pcm/etc. (actually a couple) to choose from in the garage.
Plan will be to repin my existing harness, and rob whatever wiring from the harness I need.

I debated heavily on an LS engine swap, but with all the misc. odds/ends needed, and the same smog requirements, this is the cheaper and easier way to go.

The swap will need to comply with CA smog, so I'll need to add a 2nd pair of o2 sensors.
I'll have to state that it is a 2002 computer system so I hopefully can eliminate the EGR valve. Hoping the smog referee will agree with this?
If not, then some fabrication will be required to utilize the computer controlled EGR valve.
Since the donor 2001 system EGR is sorta remote mounted, I think it could easily be made to work. Would just be a matter of redneck engineering.
The EVAP system shouldn't be hard to get working, if the 0411 cannot utilize the LT1 solenoid, I'll just use an LS solenoid.

From past reading online I recall being able to control an early 4L60E (1994) transmission with the 0411 by changing a few things?
Or add a floppy pwm solenoid in the pan?
I just can't find the thread. Can anyone verify this?

I was also wondering if it would be possible to utilize the LM7 truck injectors, and a different fuel pressure regulator?
My injectors are likely OE and 14x,xxx miles, I have several sets of LM7 injectors, one set has already been cleaned/flow tested.
Need to research this more though. I know they make adjustable regulators, I just don't recall reading/seeing anything about LM7 injectors being used.

Pretty stoked though, looking forward to this project.

My two cents when it comes to emissions, is to try and retain all emissions related equipment from the vehicle in use.

The LT1 / L99 EGR should have the same 5 terminal connector as the LS style EGRs did. Both will be a "linear" EGR, and the 0411 PCM should control the LT1 EGR just fine.

With an LS engine, the EVAP Purge Solenoid receives 12 volts of power from the fuse block, and the PCM (0411) grounds the solenoid to activate it. If the LT1 EVAP solenoid functions the same way, then 0411 should control it correctly.

As long as the Multec 2 (LM7) fuel injectors fit your intake manifold and fuel rail correctly, there is nothing wrong with using them. GM has provided all the injector specific data that you will need to properly program them - unlike many aftermarket fuel injectors.

If you currently have EV1 style fuel injectors, these use "pull to seat" terminals, meaning that you will have to cut the wires to remove them from your wiring harness. The Multec 2 fuel injectors use "push to seat" terminals, which means that you crimp the terminals to the wires, then insert them into the connector.

If I recall correctly, the 1993 and 1994 4L60E do not use a TCC PWM Solenoid Valve Control (pin U in the later 4L60E connectors). The TCC works similar to a 4L80E. You should be able to make it work - but I have never done this before, so I don't know what would be required.

I am a huge proponent of using the 0411 PCM in older platforms wherever possible. They work great, and are user friendly to tune.

The '94 LT1 EGR valve is vacuum operated, via an electronically controlled vacuum solenoid. I may retrofit the later LM7 style EGR just to cover my butt?
In CA the year of engine dictates the emissions devices. So usually defaults to the newer engine.
Even though it isn't an engine swap, that is how the referee will look @ it during the inspection.

I have grown tired of the OBDI stuff, and am really excited about the project.
