fitting a k series engine into the tr7

[alecthomasjames]

has anyone done a k series conversion? with the current price of fuel doing a v8 conversion means a bigger fuel bill than i can afford. i recently ran an mgtf 160 which could manage 35 to 40 miles per gallon. dispite the known headgasket problems with k series engines. ( east to cure by fitting uprated gaskets and a stonger oil rail) i think the k would bring an intresting update to a tr7.

Sorry not me,

I went down the dolomite sprint route to get that bit of extra ooommph, I would be very interested in seeing your progress should you go ahead with it.

Best of luck.

Hi

[:)] WELCOME TO THE BEST TR7 FORUM IN THE WORLD EVER [8D]

Wondered about this one myself, would fit in there with space to spare. As you say replace the head gasket, the only real weakness on this engine once they sorted out the valve stem seals, crank shaft end float and piston slap faults they had, fit the later steel dowels and junk plastic original one's.

Could always fit the turbo engine out of Rover 75 18 T, with a VVC cylinder head (solid cam fitted ) you should have a little rocket [:D]

Saw this MG at The Ace Cafe last month, running a engine similar to above through a sequential 6 speed box, running reasonable boost had well over 250 bhp.






A very tidy install, loved the fuse box top of the picture very neat.

This sounds a good idea to tell you the truth. I had a friend back in the UK who always said that I should of done up a v8 rather than my 2lt engine. I replied by saying that with the way petrol is going up and going to go up further, I did not want to waste a lot of money on running the v8 as a day to day runner. So one like this in our 7's does sound good.

It should be possible to get 40mpg out of the standard TR7 engine should it not? I used to get over 40mpg from mine on a run when it was standard apart from the addition of a pair of Webers.

John, that probably depends on <u>which</u> gallon you're talking about? UKg or USg...
Why on earth can't you guys at least unify on ONE type of gallon (if you now stubbornly don't want to join the rest of humanity and use liters)?!? [}:)]

[Jolyon39]

they can't do that Odd...... it would mean that Napoleon and the french were correct!

This is why the English and associated countries all drive on the RHS, well I am told this is the reason.


By the way, what MPG does the standard 2.0L EFI achieve??

Jolyon

[alecthomasjames]

Im English so obviously i use the English gallon. i have yet to see any car magazine refer to the mpg of a car in litres. this is because using litres as a measurement would show up just how much of a rip off the cost of fuel really is.
Tell most people a litre costs £1.38 and we will moan a little, tell them its over £6.a gallon and they go mad.
Especally if like me im having to spend close to £100 a week on fuel going to work. cost of living rise boss. yeah right with the current economic situation the company cannot afford it. funny how we workers have to foot the bill is'nt it. Any way back to the question. Thanks for the intrest in my k series conversion idea. as i said i ran an Mgtf 160 for 2 years, once i 'd repaired the dreaded head gasket problem it ran faultlessly. what did impress me was what a great power plant it was. no matter how hard i pushed it i always got around 35 mpg. i have seen this conversion in other cars (MGB) and it works. i noticed in an old classic car magazine that S&S conversions did a rover engined car to evaluate once. i wonder what became of it?

Hello Alecthomasjames

This has been done! But fun is with the Rover 220 Turbo (M engine) you need the engine plate from a Leyland Sherpa so you can connect the LT77 or R380 ... looking for a photo ...

I've gotten just over 40 mpg out of my Spider efi (just had new plugs, wires, cap) but that was optimal. Running at more "fun" speeds takes it down proportionally though. Csn't see running a V8, did that with my Javelin at much lower gas prices, thanks but no thanks. Guess I'm cheap (or poor). $1.23/liter currently.

I toyed with the idea of fitting a more modern engine.
Looked at various options including Rover K and T16 engines.
Even trial fitted a Ford Duratec in one of my cars.



But I have decided to stick to the Sprint engine, but it will get fully adjustable electronic ignition and injection for better overall performance and fuel economy.

But if you like to do an engine swap for the fun of it, go for it.
Should be interesting as the lighter K-engine should change the balance of the car a bit [:)]

You are correct the clue is the "Right hand side" as opposed the the "wrong hand side" of the road [:D]

Ken Wood has put a 2.5KV6 from a MG ZT into his Dolomite Sprint - if it fits in there,I would think it would fit in a 7 -
looks great and sounds even better

Or fit a V8 with LPG, I get in cost terms around 40mpg and with all the torque and aural pleasure of a V8.

[richards]

Whilst the K series might have the horsepower I am not convinced it has the torque. The 7 is a heavy car (try pushing one!) and most rovers are quite light (pushed loads of those) so you might find that after all the work involved in jamming it in you have to thrash it to go any where which will of course kill the fuel economy. The turbo version might be ok though. KV6 sounds interesting but make sure its from a 75 and not an 800, they made loads of improvements to the later engines. 2.0 M or T series engines should be ok if you want to stick with rover.
