Whenever a subject such as an engine transplant comes up people are always going to respond by by asking questions and pointing out potential problems & issues, personally I don't consider that a bad thing as it's a complicated subject and the OP, whoever that may be, may not have considered all the ramifications and it also allows the rest of us to learn things about transplanting engines.
There are also going to be people who question the sense of performing an engine transplant unless it's to produce something that doesn't already exist as it's an awful lot of money to reproduce a car that you could buy for less - I don't mind admitting that I'm in that camp - but if someone wants to spend their money doing it that's their prerogative.
I don't think that the majority of people are having a pop at JE - that's certainly not been my intention and I hope it hasn't come across that way. If you're going to post asking for comments you have to be prepared to accept the fact that you are going to receive a broad spectrum of replies but, sometimes, JE's responses to what he perceives as 'negative' comments just seem to escalate things.
Agree with you. People are not having a pop at the person, but to some extent the idea, but meant with the best of sentiment. These seem to be based around value for money, complexity, resultant car, etc. not the individual.
I've done 3 or more engine transplants in my life. The first 2 were simple. Bigger engines in Minis, etc. and in effect just dropping them onto the existing box and all in the pre electronics era. Even they are time consuming and expensive. My most recent became a huge project of turning a 2WD diesel Jeep into a 4WD V8 petrol. It took years by the time I'd shook every possible issue out of it. Electronics, overheating, driveshafts breaking, prop angles to fix. I could have easily purchased a high end comp truck for the price, but at least I converted a breaker into a globally unique truck and have had a decade of European competition out of it
For my 2p worth JE can do what he wants and spend whatever he wants on the car and respect for doing it. His money, life, time and end results. For now I keep all my modding to bolt on and offs and things I can swap over in a weekend.
What I'd love to see is a real list of what needs fixing to make a 3.0l fit a 2.0l
From top of my head:
Engine
Gearbox
Prop
Rear axle to get the right ratios
driveshafts
Brakes to match (subject to separate thread)
ECU's for engine and gearbox (everything from simple mapping to make the odometer, fuel pump, myriad of sensors. etc. work)
Mapping of same to make it work from speedos, etc.
Exhaust system, brackets, etc.
Cats and sensors
Replacement springs
Radiator, fans, etc.
Steering rack, hubs, etc.
.....and I'm only tickling the surface based upon experience
To do this I'd want a decent workshop, 2 or 4 post lift and a tame electronics expert who's done this side of it. I'd want the car off the road for 2 months as nothing is simple as it seems.
Just my thoughts.
