Sportsguy83: Read my posts above. A complete and (nearly) flawlessly working OEM CAN Integration can be done for less then 1000bucks. No guessing, its proofen. I did it that way. Use the link below and watch my YT videos if you dont believe. There are some minor issues with fuel usage readings and I was not able to use the FL cluster in a pre FL car. Besides that nothing what's different from OEM.
I understand your point since you maybe had issues. I expect mainly Electronic and Software issues, as I heard from many owners of LS swaped 86'. But if your specific swap wasnt done well in that point, you cannot generalize your expierience.
Swapping is expensive (as a well done FI build is expensive too), no doubt. Especially if you are forced to trust other U's and cant do it on your own. Many swaps I see out there done by so called professionals are nothing I'd ever like to have and without the slightest doubt nothing I would like to pay money for. But thats another story.
I dont know what exact typ of swap or turbo build you had, but I can say that I had both and I DEFINATELY would NEVER change the 400+ LS3 hp against 400+ Turbo hp.
As well, I dont agree that a swap is to be considered for track only. Even if the handling of mainly road driven LS3 swap 86 is not effected negatively in a considerable manor, this weight penalty is exactly what NOBODY want to have in a race car. So especially for racing I would not recommend to swap. Take the money to fully build the FA20 and expect regulary full maintenance. If you dont have the money for that, then stay close to stock and live with FA20 as it is.
I would recommend LS3 swap for road use cars, since a LS3 swap, if well engineered and built, is the way easier option to get reliable and longlasting 400+ hp than a turbo.
As well, I would never take a turbo build in this power region for a 3000mile holiday trip accross 3 different countrys and beat it over the hill roads arround the holiday location. Especially with a build which had only something arround 300miles of test before.
The LS swap passed this test without any serious issues. And the reason why I even tried to do this was, that there is a mostly factory engine and drivetrain and a working software and electrical system. And it seems that I was right.
BTW, I did the LS3 swap on my own. But I did it in Europe where most necessary parts are arround 20-30% more expensive then in the US. I developed a own mounting kit including A/C Adapters and engine dressup. I manufactured many of the custom parts 3-4 times until I had the final version which satisfied my expectations. I traded of the no longer needed parts of the 86 and the parts of the spender car. Overall Im under 20k€. And thats for the 1st car buildt. Any further car could be way less if the engine is taken from a reasonable spender car and its done as a DIY.
A FI build with same power and level of relaiablity and longlifety would be not less. I did turbo builds before, with development and as well as build to print. Both would be in the same range as LS3 swap if done on the same level.
Nobody (or at least way less people) come in and answer the question "how to make a FI build" with phrases like "dont think about it, sell the car and get something else". Realy, a FI swap is EXACTLY as financialy unresponsible or not as a LS swap. There is not one financialy responsible reason to modify cars. If you want to safe money, buy cars at the dealer, dont touch anything, just drive. And when you are done, sell it and forget.
Again, it was never the question if swaping is financialy responsible or if a used random sports car with compareable performance is cheaper. As well I think nobody is helped with another pro or con engine swap thread. The question was how to swap on budget. Nearly no post in this thread is answering this question, including yours. As long as the discussion isnt about the Initial topic Im out now.
