Capri Diesel engine choices

[pauly22]

Hi,

Very good chance tomorrow I'll be the owner of a 2.8 special,

Currently l have a 320cd bmw with 2.0 4 cylinder engine 150bhp. But I want a capri to be my everyday car, my current capri is having a boa swap,

The sierra/p100 engines seem the best bet, but are they quick ? I'm not looking to set the tyres on fire but be able to keep up in traffic etc? What's the mpg like? That's the only reason I'm considering this, my bmw does over 50mpg on the motorway and about 45 average. I need decent economy, use it for work a lot at times, girlfriend lives 120 mile round trip away etc.

There 3 main choices

1.8 sierra diesel with type 9
2.0 bmw diesel with 6speed
Or maybe an older straight 6 bmw diesel from 325/525 omega or p38 Range Rover with 5 speed box.

My plan is to sell the engibe and box, rear LSD axle and front legs off the 2.8 and possibly the injection fuel tank and replace with normal axle 2.0 front legs and a non injection tank, then use the money to source an engine and box and sort other things.

I've got a welder so can do a few things, but don't fancy rebuilding the whole thing,

Anyone got a thread on any of these engine swaps, looksd through the forum on the the engibe conversion pages and couldn't spot anything.

Many thanks

Paul

Same Forum, same section, currently on the same page:

See my project thread. Iv put a 530d engine and gearbox in my mk2 Granada.

Keep the injection tank, you'll need to return pipe with a diesel anyway. What about LPG rather than an engine swap?

I think any diesel engine that's good will be a PITA to swap into anything other than where it came from, and anything that is an easy-ish swap is most likely going to be highly underwhelming in the performance stakes. I think you'd really need to like diesel engines to go down this path, it isn't going to be a value-play so try not to sell it to yourself from this perspective. If you want a diesel Capri then go for it, if you want to save cash then an LPG swap probably makes more sense (but is less interesting).

Easyest swap is the sierra engine (if you can find one) but not the best engine out there for sure.
35 to 40 round town, 50ish on a run with a decent rear axle ratio (3.44 or higher), they are not so far off modern TD on MPG but they are on power, you can get them up to 100+bhp but they tend to loose reliabilty the more you go for, an intercooler, a wee bit more boost and fuel will see 90ish BHP with reliabilty.
If you want more i'd start elsewhere personly but as said paying £500 more for an conversion that only does 5 MPG more is not really ecomonomicly sound ?

There is also the option of the merc om series diesels, which have been used in swaps into many different vehicles now, or vw diesels using a Volvo gearbox.

I'd have thought something like a vw 2.5/2.7 tdi v6 mounted to gearbox of your choice would work well (Volvo m90 probably bolts up but only a five speed). Should match the performance of the old Essex at any rate and be similar size and shape to fit?

Really want to see a diesel Capri done!

Economically I would guess the 2.8 should return 20 mpg on a run probably more if driven economically, if you work it out cost wise on gas that would be the equivalent to doing 40+ mpg with LPG at roughly half the price of petrol (or considerably less if you live near Birmingham). When you are done you could take the kit all out/ off and return it to standard if you want.
I'm not a Capri person but I would have thought if you ever wanted to resell an unmodified 2.8 would be worth considerably more than a ex 2.8 with a load of 2.0 bits and running a diesel?
I'm not trying to put you off, I always wanted to build a rally lookalike diesel Mk1 escort so I could afford to run one years ago back when diesel used to be the cheapest fuel by a big margin.

LPG never gets the uquiv of twice the miilage unless you go over a grand and get a fully ECU controled one or go liquid LPG inj but AFAIK they need to run piggy back in the cars injectors and the 2.8 cologne is MFi so your going to be looking at 35mph equiv at best IMHO(older mixer systems are even worse), then as it a non unleaded engine you'll need a flashlube kit to protect the valve seats, the costs start to add up quickly.

swap for a 2.9EFi (or find the top half from the very rare 2.8EFi) to LPG? no body mods, fully reversible upgrade? 50mpg (equiv)

I have a chipped 2.5 Omega straight six TD in a Scimitar and it goes VERY well - am also building up a 3.0 Essex EFi in another.

I'm not doubting you but from my experience IF the lpg is well set up and correctly spec'd for the vehicle it is fitted to you can get the virtually the same as and in some cases better mpg, problems start when you have badly set up systems with whatever mixers could be made to fit easily/ were cheap/ on the shelf the time.

Apparently there is one injection system one the market that doesn't need an ECU to piggy back off as i was pointed towards it for the turbo pinto.

For an unleaded engine you would be needing to run an additive anyway to save the valve seats, Flashlube kit is about £30 for the simplest vacuum based one, OH's car has one of the digital ones don't think its had more than a litre of fluid in it in 5000 miles.

A BLOS lpg carb £90 should be fine on that engine - it works like a proper carb rather than a fixed mixer

I've fitted a 306td engine and LDV van r380 5 speed box to my Cortina Mk3 estate, its very good,my bro has a Sierra diesel, that's like a slug on valium,it maybe more work to go non Ford, but its worth it!

[pauly22]

Thatnks for your help.

I want it to be relatively simple to do so. I'm bidding on a 1.6 laser.

Will sell engine and box off.

Get s complete sierra td p100 lump and box

Buy a v6 Capri box and switch bel housing from td box.

Pinto engine mounts on the wrong sides,

Probably fit a low pressure pump and swirl pot, as I don't want to go round a corner and no be able to pick up any diesel.

I'll fit and intercooler for frw extra horses.

It's all for economy. I have a 24v Capri for fun but want a cool daily to plod about in.

I had a transit connect with the same engine I think, blew it up but it wast that slow.

Cheers
