What to do with spare GTV6 2.5L engine?

When I bought my lovely GTV6 it came with a complete spare 2.5L engine on a stand.

No idea its condition.

My GTV6 was previously track raced. The engine in the car is a standard appearing 2.5. It's perfectly clean, has no leaks, etc. - I'm tempted to assume the engine in the car is a fresh rebuild. No idea if it's been modded for more HP. None of the service receipts that came with the car mention mods or an engine swap. I suppose an owner could have done the swap.

So, anyway - I have in mind to "do something" with the spare 2.5, but what? Got any ideas? Do 2.5's respond effectively to builds for HP increase. I'd figure starting with a 3.0 would be more effective. Any crazy ideas even?

- Kit car engine? (The Lancia Stratos kits call for a FWD setup out of a 164 or 166)
- Coffee table? (My wife might not appreciate the beauty)
- Keep it in case I blow my 2.5 on a track day? (Rebuild the spare while I enjoy the stock 2.5 and drop it in for more HP later?)
- Boat anchor?

Thanks for any and all comments - !

The 2.5's do respond well to some mods. S cams, hi performance injectors and pistons, etc. etc. I know a guy who is pushing close to 200hp at the wheels with his modded 2.5 (without forced induction). It's a lot of work, but certainly possible.

Hold onto it and find a 164 3.0 V6 core also. You can use many of the 2.5 pcs to make the 3.0 fit in the RWD GTV6. This is currently what I am working on. I also had a spare 2.5 and wanted to make something of it. I still plan on holding onto my 2.5 once I've stripped it of the oil sump etc. Wrapped in a large plastic bag with a light oil on the liners/pistons, it should be around for a long while.

Keep it and slowly rebuild it with nothing but the best parts. At most, throw some good cams in it.

Agreed. Your GTV6 deserves to be a 3L.

Oh. My. Goodness!

I never knew! I just bought a 164 LS w/3.0 24vÖ. it's getting Q intakes and a chip. I'll pickle the 2.5 until the 164 rusts to pieces and make a 3.0/24v for the GTV6! Fun stuff.

Build a Locost. I've got a few 2.5s and I always think instead of spending money to get more power just put them in something lighter.

I like that idea. Sounds intriguing - What's a Locost? (Has anyone put a V6 in a Junior Zagato?

Considering I expect to have a 3.0L 24V drivetrain for a project in a couple three years, I've already looked at the Lancia Stratos kit by Lister-Wells and the Hawk HF 3000. Seriously attractive possibilities..

Happy New Year,

A Locost is a Lotus 7 knock off. There is a guy in Eastern NE that has one built from a spider - neat car. I imagine a V6 would be a bit over the top - if there is such a thing.
