I am currently looking to upgrade my car, a Triumph TR7, which is a small British sports car from the late 70's. To say it is lacking in the power department is an understatement. I am looking at my choices for an engine swap and I was wondering what advice y'all might have about putting the Solstice/Sky engine in my car. I have started looking at other engines like the Honda S2000 4 banger and the Nissan 350Z V6 and I know some of the difficulties in using these motors. The Honda has part of the ECU integrated with the gauge cluster so that has to be swapped also. Are there any major issues with the Solstice engine or should it be an easy swap, other than fab work to get it physically into the car.

Thanks
Holt

there are some wreaked solstices and skys that still have a working engine and harness. I think the things you would need to run it would be the engine, harness for the ecm, and the accelerator pedal. If you do some searching on this site you can find the thread that talks about someone selling a working 2.4l that has everything and you can ask him about it.

Maybe think about using the turbo 4 in the GXP or Redline. Great engine and should be relatively easy to swap compared to the other engines u mentioned.

Look instead at what was offered back in England as far as a V8 in the TR. Amazon.com: How to Improve Triumph TR7, TR7-V8, TR8 (Speedpro): Books: Roger Williams
A Rover (ex Buick) aluminum block V8 should be readily available and since it is old school hard-wired , even in f.i. form, the swap will be more straight-forward.

No, I do not work for GM or any subsidiary or supplier.

I think one of these engines would do nicely in a TR. I'm pretty sure this will take care of alll your PCM needs.

MSD EFI

I just looked throught the applications. It seems the 2.4 is not listed. Only the Supercharged LSJ and the 2.2 L61. Sorry 'bout that.

CreateEngineDepot.com is one of this site's supporting vendors.

Try them.

There may be an engine solution available from GM in a package.

They may never have supplied one for a TR7 conversion but may have some ideas.

I have looked at doing the Rover V-8 or doing the Triumph Sprint motor swap. The rover V-8 would be a nice motor if I could get one of the more modern ones used in the Land Rovers. I have just started looking at my options on the engine swap so only time will tell which way I go with it.

I was looking at the MSD ECM and noticed it is a speed density system, I would prefer a system that use a mass air flow sensor instead. There is a company that makes one for all of the American V-8's (Mass Air Flo) but I am not sure of anyone who does it for a 4 cylinder.

I thank everyone for their help and advice on this subject.

I would suggest an LE5 N/A to start and boost it later. That way you have the best ECU in a GM vehicle (E67) and should you decide to boost you have a great starting platform. You can either purchase EFIlive or find a tuner shop that has it to remove the VATS and other module interfaces.

Though I have to say; I just helped a guy with an SR20DET swap into a Datsun Roadster and when all was said and done we ended up swapping out the stock Turbo for a smaller compressor and running with some ebay ECU. It put 240 HP @ 12psi to the ground on a dynojet and ran very save A/F ratio.

I don't know..?

You will have to excuse me but what does VATS stand for and what exactly do you mean by removing module interfaces. I am assuming it has to do with CEL codes an things that I won't need in my car that are used by a Solstice. I have never modified an EFI engine so I am not familiar with all that is involved.

I'm not sure with the can system on some of the newer cars, but you could swap both the PCM and BCM. HP tuners is available for most of the eco engines. The 2.0 LSJ Cobalt engine is the only fully cracked boosted PCM. I'm not sure about the Saab turboed version.

TurnKey was offering turboed eco sand rail engines with an efi system. The ariel Atom in North America uses the LSJ engine. There might be some leads anyway.

If I was you I would just get a miata motor with turbo from flying Miata and call it a day. Been done a million times and works like a charm.

You can also run an after market ECU with the S2000 and shouldn't have to run the gauges like you said.

I think the GXP motor would be a freaking nightmare to get it to work.

Go with the Miata...you would have good low end Torque and its less of a head ache...put one in a Spit, it was a BALL.......seal9

LSJ longblock + MS2 or Fast XFI,BS3 etc. The standalone engine managment will set you free! Dont pigeonhole yourself into a factory ecm unless you HAVE to. You'll thank me later. (when you tuning on the fly-hassle free!)
A prepped LSJ with a bigger blower or screwblower can really put it down. The same with the right size turbo can be downright dangerous...
