engine upgrades

[Lord Icon]

Any body change out the carb (z,sol, web) and upgrade to a throttle body injection system? I am commissioning a system and if i don't have to re invent the wheel it will be cheaper....
This is a stepping stone for me till I get the time and cash and energy to do the 200di swap out.

Have not heard of anyone doing it but there is no reason it cannot be done. Why bother with an antiquated TBI system when you could do a little manifold work and go to a modern multipoint efi. Systems like Mega-squirt and others are fairly easy to work with and apply to any engine.

to limit expenses and the need for making a wiring harness you could look for Saab 900's in the junkyard from year 1986 through 1993 and pull out the fuel injection wiring harness. These harnesses come out of the car reasonably easily and only require a few outside connections like power, ground, etc. They have 4 fuel injector connectors and other sensor connectors that could be used and programmed into a megasquirt computer. There is a guy on the Saab forum that makes an adaptor which allows you to plug the megasquirt computer into the Saab harness. Would probably lay into a rover engine bay nicely and you could mount the computer inside out of the elements (or as away from the elements as you can get in a rover).

I believe LRMax commissioned a FI system for his, or atleast attempted to. Might pick his brain....

There's a throttle body conversion on Discoweb or GnR. Search.

Why waste the money if your are going to swap to a 200di? That makes no sense.

Agreed...didn't even register the 200TDI swap until now.

$$$$$$

er, tbi upgrade 300-500$ no engine removal......
200di $2900 plus shipping and many hours under and in my rover engine bay.
I figure I did this with my Unimog and patented it and made a few quid.
the 200di would just cost me money as someone else has done all the brain work...
Besides, the MRS. wants to know why I just can't improve this engine that works " fine" the argument for better fuel economy just is wasted as the rover is not used that often..

What about this:

With this manifold:

and a bit of machine work for an adaptor?

You're thought process makes zero sense here. If you really think for a moment that a 70 something horsepower engine is going to be more efficient moving the weight of a series truck you're kidding yourself. If you are looking at gaining more *mpg's* than you need to consider the alternative, which would be a diesel, which also does not mean a Rover diesel either. These trucks are tractors folks, not a Prius.

If you want to improve the 2.25 that's in there now, keep it well tuned and maintained.

true...but there are certain things that a modern EFI system give you beyond the possibility for improved efficiency. The modern DIY systems are infinitely tuneable for your application and you can plug a lap top in and see whats going on. You can optimize the fuel delivery for the engine and the driving conditions. While its doubtful that you will see a fantastic increase in mpg you will likely find the engine runs better in a wider variety of conditions. However, the other side of this project is that it would be a good idea to design and build a different intake manifold. The stock rover manifolds are short and fat which tends to optimize top end hp while long skinny runners tend to enhance low end torque. So an efi system and a properly designed intake manifold mated with a properly flowing exhaust manifold and exhaust could be a big difference in the performance. On top of that you could reduce the flywheel weight and improve reving speed.

In the end you will be limited because the cylinder head design is just poor to begin with.

Get a rebuilt Solex and like others said keep the engine in tune and you'll get the most bang for your buck performance wise.

Why even bother with the 200di swap? Gutless enough with a turbo and without not much better than a well kept 2.25 petrol.

Have you ever driven a truck with a 200Tdi? Hardly what I would call gutless.

Gah! Now I have yet another thing to daydream about. Thanks, msgunny :P

BTW, what's different/better about that manifold compared to stock?

[gudjeon]

That Holley TBI is one sweet piece of kit. Hmmmmm. If/when I get a tax return...

[albersj51]

Wow! $1800!?! Im all for turning the rover into EFI, but at that price ill take my carb and like it.
