Still need to sort out the e-fans.. among other things.. also got the ac lines braze together. Pleased with the outcome. Both ends will get 90 degree fittings and it will match / run along side the heater core lines.

What radiator did you go with?

Re: LT1 GenV swap

Drew up and cut out the transmission cross member pieces out. Didn't have the stock one, and if I did, probably still wouldn't use it lol. Waiting on the hole saw bit to arrive to finish it.



Similar design I used on the LS BMW

Plumbed the fuel system. Ran out of the push loc fittings, needed one more 45*, so a 90* was put on just to get it finished.



Proper 5bar fuel presssure regulator

Just got it started a few minutes ago after some quick trouble shooting... now it's going on hold again. Have another harness to mod, waiting for a set of custom header flanges to arrive so I can make a set of long tubes for it.

Clint, I have a set of LT flanges that I won’t use. I don’t remember what I paid for them but if your interested...

Re: LT1 GenV swap

87chevy, what did you use to control your trans?

I found out the trans is a 2013 and the motor/pcm is a 2015. I’ve tried 3 tuners and no luck so far. It’s stuck in 1st gear.

Re: LT1 GenV swap

How do they know its a 2013 6l80? Using the stock 2015 ecu... do you have HPTuners? If so you can read out the data, post that on HPTuners site and ask of they can do a segment swap. I've only rehashed 2015's to 2014 If they didn't have vats2.
I got a 2015/16 flood transmission taking up space on the garage. Would more than likely need a rebuild just to be safe. Havnt taken the pan off, just stuffed it under my table saw.. I bought it with a hydrolocked motor for mockup before in-game across the good one I have now.

Re: LT1 GenV swap

Ya know... I think I have been BS’d again. Spoke to clinebarger today, just need to change out the valve body/Tcm. He said the only issue is when they come from different types of vehicles, 2013 car vs a 2015 truck, also he said the guy doing the programming could have fried it if he doesn’t have the correct equipment.

Thought?

Re: LT1 GenV swap

The tag on the side of the trans decoded it’s a 2013...


I don’t have squat, I’m relying on others and what they say..possibly my issue all together.

Re: LT1 GenV swap

Hopefully you get the trans sorted out.

Got another swap harness wraped up.




Still waiting on the header flanges, hopefully they will ship out late this week. Once headers are made I'll reinstall the fenders and hood and take it around the block.

Re: LT1 GenV swap

Still haven’t gotten the trans fixed. New VB/TCM and still can’t program the trans TCM. Checked continuity from TCM plug to data lync connector and all is correct there.

My head is swimming in a lake of frustration on this...could there be something wrong with the ECM?

There is only 2 other wires that would be modified for the TCM, battery constant and the crank/run.

Re: LT1 GenV swap

Hours and hours worth of cad gets me this far. Exhaust ports exactly centered on 1 3/4 tube. I chose 1 3/4 since I have lots of bands left over and the port as well, when a 1 3/4 tube is shaped like a rectangle, the same size. I'm not to crazy about the flanges I ordered and received so drew my own.





Adapters screwed into the nutserts



Just threw some tubes on it just cause.

Mann, the MDF flange is way better than a steel flange and a starter tube in said flange with the insert adapter.. this way is much much much more stable and won't fall out! So wish I had done this on the last set of headers I built!

Hope to get the driver side modeled tomorrow and maybe get started on chopping it out of tube. Still need to make another saw fixture for the u-bends

Re: LT1 GenV swap

87, do you do tuning? If so, would you mind answering some questions for me. I can get a tuner here that is willing or able to fix my issue.

Please pm me your number and best time to call, if your ok with me calling.

Thanks

Re: LT1 GenV swap

PM sent

Got the driver side mocked up. Wound up sending my drawing file of the header flange to the later cutter, was not happy with the stainlessworks flange. Those should be done in a few days.





Thought about sending them out once I have them welded up and sell them but speed engineering says they will be making them at some point so not sure if its gonna be worth it.
