Thread: Reusing Auto Engines.

I feel dirty for saying it, but I drove a turbo diesel focus the other day and it was so so nice to drive. Real wedge of torque from idle, and hauled arse after that.. Trim off all the Ford-ness plastic crap and you're left with something useful

Yeah, the wee diesels are pretty good. Trouble is the road user charges kill the cost advantages. Doing the maths my Bighorn is $26/100km and the Forrester is only $18 not taking into account servicing. With a boat, where you don't have to pay the road user charges, there would probably be an advantage. With the amount of use it will likely get that advantage won't be much, if anything, with servicing costs. So I think I'll stick with petrol for the boat.

Know the feeling, people hear I have a twin turbo Subaru and say oohh that must be expensive to run, but it and the Terrano both run about the same $20/100km.

The QD32 is basically just a TD27 after a few steroids.

1UZFE?

Probably a bit too much engine. Like the idea though.

A straight 6 is probably good for space, long and narrow so easy to get down the sides in a small tub. Unfortunately with the trend for FWD cars to maximise cabin space they are not suitable for cars so pretty scarce. There will be a few straight 6 commercials but they will be heavy. I think a V6 is probably going to be the best option.

A 1UZ is pretty compact and light for what it is. The Beamer mention above was cast iron block and alloy head if I remember correctly, and the 1U was 2 cylinders shorter and 20kg lighter, with double the power and torque. There's a shit load avail off the shelf for turning the humble Lexus into a boat motor too.

Yup.

Heaps of guy's using them in boats so can get hold of marine manifolds etc.

Also they're quite plentiful and reasonably cheap for what you're getting

What rpm motor is the gearbox and leg designed for?

At least three sump configurations too, I love em. They are basically two 3sfe engines on a common crank.

They are geared for the B30 at 5k.

Yeah, I think the output is too much motor if you catch my drift. I think for a 280 or 290 leg it would be good, but that would have to start with a whole new transom I think.

So high rpm engines are probably out unless gearing can be changed?

I don't think there would be any issue going up to around 6k. May need a prop change. Think gear changes would be difficult to obtain.

Leyland P76 may be worth considering. Cheap to buy already marinised from the jet boat crowd, develops good HP, lightweight at about 150kg plus accessories.
