940 turbo and manual swap

This is the stock NA Volvo experience. I am painfully aware of how slow my car is when not in boost, which is probably 75-80% of driving conditions for me.

I would strongly suggest Googling "Volvo Regina tuning" and seeing what comes up. Unfortunately, unlike Bosch LH, you can't really get off the shelf chip tunes for Regina. If you can figure out how to tune it yourself, great - all the normal hop-up tricks will probably work ie: cam, shaved head, exhaust - making the car lighter etc etc.

If you're still talking NA, take a quick gander at this very helpful thread. See if your goals align with what you're prepared to do with the car.

NA performance? Look here.

T cam? A or V cam and shave 1mm off the head? A T cam would make it scoot around better in the window that the AW transmission would operate in and they're cheap.

125whp (20% drive train loss through the automatic puts that at 155 crank) is your realistic limit.

Considering that off-boost, a stock T cam turbo car probably makes sub-100 whp, that sounds quite cozy, actually. Driving an S90 made me envious of NA power.
 
As far as I know nobody has tuned Regina. You could try and figure it out but you're rolling your own and probably need to be pretty deep into reverse engineering to figure it out.

It may be hard to find a manual 740 but this is much harder and results are not guaranteed.

150 whp is a fairly significant amount from one of these engines naturally aspirated.

I kind of said 150 just as a ballpark. Something I won't go over.
 
I found a video from Drifts n lifts showing that the Regina isn't entirely useless. But the question is, what all was done to this car to make a standalone ecu work.
And what was done before the ecu was swapped, because supposedly it was being slid before. Have been watching this guy for YEARS, and still somehow realized I lack a lot of knowledge about Volvo's. But it is reassuring knowing that there is a way for power gains.
 
Regina is awesome! For a bone stock daily driver. If you plan on doing anything more than a mild cam swap, get another car. They are not tunable - moreso the MAP sensor on these cars does not read more than 5-6PSI above ambient and was intended for NA applications only. Short of the costly and time consuming process of swapping to a standalone ECU, your options are extremely limited. As for manual swapping, a friend of mine completed an M46 swap on his regina 940: it took a year to find a flywheel with the correct trigger pattern, and none have shown up for sale since. Best of luck with your car: highly suggest you refresh the suspension and enjoy it as is while you look for a factory manual turbo car.
 
The easiest path to your goal is to sell the car and buy a Turbo 7/9, or, Chevrolet LS swap the car you currently have. It will get better fuel mileage with an LS and have all the power you will ever need. You will also have a transmission that will hold up to what you intend to do with the car.

I see. If that is the case I may as well make it a bit more simple. Although I still can't stand it being as slow as it is. Is there any simple things I can do to make it a bit quicker.

You can make Regina system a bit more powerful with the usual n/a mods. Like a higher flow exhaust, install an A or B cam which both work well with an automatic. It would benefit from a slight bump in compression if you are willing to run premium. That's all I'd consider doing to a Regina car. They are a well engineered daily driver that not many in the enthusiast crowd modifies. I do seem to recall a thread a few years ago on a turbo+ Regina car but that's about it. No one has tuned the software that I've read.
Edit:Didn't read the last few posts before I posted. It's an overall conclusion from the years. My friends drove a 93 Regina 940 wagon and it lasted an easy 300k miles before having major issues.

Yeah, turboing the Regina car is now completely out of the equation for me. If I am going to do heavy modifications I rather wire in a standalone, that removes a bunch of the headaches once done it seems, and if I really wanted, I can reuse that on a turbo car later on. A minor cam, exhaust and intake are perfect for now, and maybe losing weight. I am not looking for a super fast car, I mean I daily'd my 1988 Mr2 for the past two years and had lots of fun with low HP. Just want to be able to get a little sideways here and there which the Mr2 sucks for.
