Could these not be homemade using a mould of the lhs one.
Make a mould from plaster.
Then pour in a rubberised or Maliable material. Along lines of bluetac. Or even flour and water?
Offer up to rhs to allow you to adjust the shape. Allow to harden then make new mould from plaster and so on?

Looks brilliant mate, where did you get the stainless steel from to make those?

Think your gearbox will let you down

Besides, power is not everything, getting it on the road is. 1.8 T with FWD outperforming a 260?...........Doubtful but stranger things have happened

And the 260 isn't fast by modern standards, but gets the power down quite nicely once rolling

funny, having owned all the models in the range, the 1.8T is my preferred option for tuning.
you won't need anywhere near 260bhp to outrun a standard 260. Weight

But of course, I wait to be proven wrong when my VVC Hybrid Turbo'ed 1.8T with a weak gearbox is on the road

Didn't know you have owned a 260 as well.
What did you think of it?

Trying to shave 3 secs. of the 0-60 with a 1.8T to beat a 260 seems a tall order

1.8T in your case 204 BHP and 1500kg = 1 BHP / 7.35 kg
260 in my case 275 BHP and 1750kg = 1 BHP / 6.36 kg

Go figure who has a better power to weight ratio

You'll need to get up to 235BHP to match that

compared to making a 600Ti faster than a Lamborghini Diablo was a tall order but acheived

I've had two ZT260's. I love the sound of the V8 but I felt they were very heavy to get going. I'm sure an SC version with 400bhp would be much more like what the chassis was designed for.

the 1.8T is much lighter and once they are rolling, the FWD bit is much less of an issue.
Gearbox should be fine tbh, it's the bottom end which may need some more work, but after the VVC head with all it's custom work and the blower are done, i'll of either blown the bottom end or be already building up a forged unit.
There are so many tuning parts out there that people forget they were used in Lotus and Caterham's for many years. They can be made very very quick.
All fun and games but I feel if you want more involved fun driving then a tuned 1.8 is the one to have. If you want a factory sedate but smooth driver then the 4.6v8 is hard to beat.
Now if only they'd got round to putting the 5Lv8 engine in, then we'd be talking. Check out Sean Hyland built crate engines. Been tempted but with so few 260's around, they are one of the few cars I think should remain factory spec but you will have to agree it's quite old technology on them but to me, that was the original attraction - a classic muscle car in a nice shell.

I like to keep mine as standard as possible but have some standard upgrades.
Fast enough for daily use, good in gear acceleration and it turns heads.

I'm sure the 1.8T can be made faster but at what cost?

As far as involvement goes, the 260 is pretty good on the twisties and quite balanced as well. Suspension set-up is good for a car this size and weight.

Good to know that different cars in the same range can still create different emotions

Increasing the performance of a 1.8 to beat a 4.6 is an interesting idea which I'm sure can be achieved,but I would be concerned as to the reliability of the car and I can't imagine it would be any cheaper to run than a V8 in that state of tune .

I don't think the main focus of the 260 is on performance although that of course can be upgraded to nearer 400hp, and beyond that if you have the money.

Anyway good luck on your project.
