Would the engine and box actually fit? If so that’d be...erm ...interesting. 250bhp and tuneable from there. Would probably spin the wheels in 4 gears!

I believe the Volvo engine is the same as a Ford EcoBoost which is the same dimension as the duratec... but you would struggle to get all the electrickery to work and space /cooling for the turbo

I have a spare engine and trans sitting
Roughly they will fit

I read about people getting a twinc to some high numbers for racing. Albeit mostly for vintage stuff.
Many folk have put fuel injection in
A straight six.

I am not sure how closely related engines are.
Maybe as close as classical music is to polka, or hip hop to jazz

They are simply robust, high torque/power combination.
I was thinking for my old 70’s Volvo 142. Which has more of a rally set up. But I am not rallying anymore.

Ah well...

I favour Japanese engines for my transplants, the Toyota 2ZZ-GE (supercharged) would be a nice choice if you could get it to turn through 90 degrees etc and of course with all modern engines you will need 14 kms of wire and ECU(s) etc.

Best thing to do is get one of those newer and more reliable Elan SEs (the M100)

and get rid of that nasty Plus 2.

I suppose I could take it off your hands... :D

Japanese reliability is key. Not to mention. Those toyota engines come from one of only two vacuum forges on the planet. Most of my sleds (ski touring) and trials bikes use the superior metal from Yamaha's forge.
Yamaha eh

1. Turbo engines are boring!! Boring in terms of sound and character. High revving, good naturally aspirated engines are far better. Doesn't take any brains with a turbo engine to just pump up the boost for more performance.
2. I know from experience working in the industry that it's really a myth that the Japanese are always better in a quality sense than other manufacturer from other countries. When there is a problem it's usually a BIG problem as problems usually get swept under the carpet for a long time. Yes manufacturers with motorcycle engine design experience usually produce good engines - in particular Honda who are the most innovative of the Japanese companies and who don't contract their innovation and brain work out to others like Toyota does with Yamaha - or copy others as Toyota copied from the Cosworth BDA the basic design principles for their 4AGE engine introduced in the 80's. Even their much promoted "Scissor" gears arrangement for driving their double over head cams was originally a Cosworth innovation used in the DFV.

Sorry I have to qualify - MOST turbo engines are boring in terms of sound and character. The Italians, for example Ferrari still manage to make them sound and feel good.

Sure, depending on if you enjoy the sounds of free energy (wastegate working) or the sounds of air rushing into a plenum
Engineers have always stolen others ideas, its why were’ progressive.
Like music, or the chicken and egg.
3,4,5,6,8 and 10 turbos or na all have distinct sounds
After they started turboing all diesels, no one has gone back to na
How many cars now a days dont have turbo, only a few here in na

I fer one, prefer free energy

Didn't find the turbo in my Elite boring, nor do I find the turbo in my M100 boring (with the boost pumped up to 200hp) nor my BMW...the list goes on. :D

Keith Duckworth was no fan of turbo engines. I thoroughly agree!!

Many quotes in this regard were ATTRIBUTED to him but...

And if he actually DID utter those words it may well have been in response to the Cosworth engines finally losing their well-earned place at the top to the turbo engines in the early '80s. but in the mid '80s he jumped aboard the turbo train with both feet.

Cosworth have long been involved with turbocharged engines.

Is the rest of the drivetrain able to handle the torque from those engines? I imagine they would produce at least double the torque of a high horsepower twincam which is a different level of stress on various components.

I suspect the base power of a T5 to be that of a highly tuned twink
The racers might chime in

For me, free engines not requiring much work, that the industry has already made adaptor plates etc. Aftermarket fuel injection etc...
Vs $20,000...

I suspect the weight of the engines (twinc and T5) to be about the same.

Rather, if one was to modify a car. As in not original engine transmission. If one was concerned in speculative resale of said vehicle.
So, if I was changing transmission in a twink from the 4 speed. Which we all know alters originality. Or going to zetec or duratec etc.
Maybe the non turbo variety of the T5, also called the T5 would be the choice. My friend has. Non turbo T5 with hot cams and free intake and exhaust which sounds as nice as my tuned duratec with cams.

My question was about the effect from the torque of the turbo, not the power. A stock Volvo T5 has 250hp and 258 lb-ft of torque. A highly tuned 1.6L normally aspirated engine (or even the non turbo T5) won't have anywhere near that torque level and it's torque that breaks and twists things. The various bits may be up to it, but Chapman didn't exactly overbuild the cars, so worth considering.

Agreed.
I am looking for options. As when the time comes, and I dont want to dump loads of money into a questionable financial pit.
When I converted my 1995 Volvo 960 Estate to turbo, it really helped towing downed Harley Davidsons. Same for my 1988 Mercedes 300ce.
Not that the elan lacks power getting up the hills, and I dont intend on towing with them. The difference is amazing after a turbo conversion. And maybe more noticeable for us in the mountains hauling kids or gear or...

Before I commit to any new projects, I have to fit a 2017 BMW S1000rr engine trans i have laying around, into a 7...When I have time.

Those Volvos are based on a B block, so I feel some alliances to their history. I dont really like the zetec, sort of care about the duratec. Maybe the eco boost is the answer.
