Very cool swap, kind a like an older hennesy venom, the purists will be even more butt hurt when your car outperforms theirs! Lol, can't wait!

Been a while- have been waiting on parts but i finally got my adapter plate and flywheel. I so now that i have the motor and transaxle in their exact location, i can start with some other systems... Coooling, Fueling and Electrical.
Electrical - the harness is built- just need to go get it
Fueling- got a set of replacement tanks and they are being dipped and shined.
that leaves cooling- here is what i am thinking on my flow and routing. I've done some research on the LS system but with the distance to the front- i have to figure out a slightly different way. I will be using all -20AN line and fittings and an upgraded radiator. I know some of you wont know where the tanks would mount but ill try and find some pics for reference.. but the pressure tank lives just next to the engine in the rear/middle of the car and the overflow in the farthest back bumper..
The steam tube i am told- can be routed back into the system and i am still unclear if my pressure tank scenario will work without going to the radiator? it sits at an angle in the front- so not sure it will have the high point.



Please critic - i'm not terribly familiar with the LS's so i can guessing but i like to have a plan before buying parts!

More pics!

Sounds a good bit like how the Porsche swap guys are doing their cooling systems, check out their builds as there are a few here.

I'm in no way an expert on how to set up the various tanks and routing. I do know that the heater core outlet/inlet need to have flow through them, i.e. loop it, don't cap it.

Other than that, looks great, love those Esprits.

No, you can cap the heater outlet and inlet without any harm. Pull the tunes, tap the ports and install pipe plugs.

i did see that- I will loop them- especially if I tap the steam pipe off of one.

Thanks! And I will check the 911 guys posts on this too.

why not use the at least a majority of the stock hard lines to run front to rear?

i thought about that but I will be upgrading the radiator and it will have AN fittings and I have to come off the waterpump outlet at damn near 90deg - like an SLC - so AN fitting there too... just makes sense to just do it all in nice new stuff. I tend to half *** things when it's a puzzle and not all the pieces are there!

With my limited experience working with an stuff, I'd have regular hose barbs put on the rad, and use the stock lines as much as possible is all.

Would hate to try and route such a large hunk of that stuff, and then secure it so it doesn't cause problems.

The rad have to be custom, or is there an off the shelf upgrade that works?

That's "sorta" true. If you live in the mountains where the engine is loaded (uphill) you should do this. I'm in the "flatlands" and have run with the heater inlet/outlets plugged (well, valved off) and have had no problems, even though I'm located on coastal TX with upper 90 temps and 80% humidity...

Currently Trying to figure out what axles i can use... I think I have found a few that can use an adapter or extension piece to make work - but still need to do some measuring. Oh, the rear brakes are a PIA as well -they were inboard and i am trying to make them outboard- new carriers or a custom adapter plate!

On racecars I have seen the steam vents routed to the surge tank directly separate from the outlet of the water pump and I think it was routed to a small -4 fitting on the rad. You would fill the system with pressurized water and run the motor to get the air out. May be too complex though and what you have pictured should work as well.

Default Steam port

This is what I used for the steam port.

Plumbs into the upper rad hose, then add in a 90* fitting and route the hose. Works great
