Hello all,
I run a mk2 8v gti which recently popped its block. At present i replaced the 1.8 with a 1.6 na diesel engine and although i am starting to enjoy the excessive fuel economy this engine offers I thought its time to put something bigger and with forced induction on... so i got myself a 1.9D turbo - AAZ - in hopes of restoring some power to my golf which at present is being overtaken by ummmm everything...
My background on diesels
I started appreciating diesels a long time ago and have recently converted my brother's mk3 Ford Capri using a mondeo 90bhp idi unit. At present its fitted with an AAZ diesel pump, lancia delta intercooler, a T2.5 turbo with 360 bearing and some other stuff in... and needless to say it now pulls like a train, throwing shame over the 1.8 zetec -130 bhp- it previously had plumbed in. Spinns 215/50 R15 wheels in 2nd gear and had to fit n LSD unit to the back because it chewed 2 standard diffs...
On a more sluggish note... the 1.6 diesel on the golf i'm running is a home assembled engine built from 4 discarded engines... Put in 1.6TD rings running in a perfect bore, and was a complete rebuild including the pump so works like a clock. It has
- gti flywheel from the old engine
- 2 into 1 exhaust kept from the gti,
- some pump mods, new injectors
- gti gearbox which has close ratios and a low final drive which makes it accelerate quite well till it reaches 90-ish mph where the engine just can't revv any more.
not a bad engine but with no replacement for displacement i think its time for the 1.9... However, since it will be used as a daily runner for short distance driving i want to be carefull about what mods and what not mods will i be putting on it.

Sounds like a good project. Do you have any pictures of the Capri conversion or of your golf?
-
yes but no ideas as regards hosting/uploading images, is there any guide somwhere in the forum maybe

testing...
Here's a pic of the Capri just after we took it out of storage before work started... and the GTI in the background :)

Starting up the AAZ after 4 years sitting on a pallet box...

thats an interesting engine/chassis combo ! :D

The Capri TD?

The Capri TD?
yea... i'd expect a big block in that thing :lol:

I had mine fitted with an LS1 engine off a vette, ran it with Megasquirt management... 450 bhp and weighing in at just 1060 kgs! was quite impressive! but insurance was too high as was road tax/liscence so had to sell it :cry: right now its somwhere in Italy. Next one i'll be buying (if i ever do) i'll do up with a supercharged 2.3L 16v duratec engine...

What parts of the engine does the insurer look at to adjust your rate? horsepower? displacement? forced induction?

this picture kind of reminds me of a chevelle

Over here forced induction adds a slight percentage but displacement kills you off ... Also some models require various no-claim bonus years to be elegible to be insured to drive them such as huge engined mercs which pop to mind. Other models you may not be insured on unless you're 25 years of age...

not the final version but you can see some of the work done...

Did not have any problems, maybe because it is a late model, i.e.1986 MK3 1.6 LS (1.8 TD now :P )
-
Awesome work! I'll be interested to see how your Capri pans out (on a VW forum...strange :D ). Did you too find rot where the bulkhead meets the front wings? I know I did.... :roll:
Cheers,
Tom

the only thing that bothers me on this engine is the exhaust manifold... the rear cyl is going to get cooked if you let EGT's get too high... i've seen it on a 2.4D where that cyl had like 60 psi compression, and the cyl at the front had about 360 psi... i guess if you're running it stock then it should be okay though.

Cool project, my first car was a mk1 Capri 2000GT 8)
Do have the car running yet?
I´m planning to convert a Scirocco GTI -77 to a diesel...
-
prothe : nop the car ran a normal carburator with a plunger pump on the old petrol engine block. All I had to do was to add a return, which i did by acetylene welding on the fuel gauge sender unit (did not do welding personally due to very thin metal but left that to a pro).
jtanguay : I share your concern re. manifold however that seems to be the only factory made one that fits! (off a non intercooled sierra 1.8 td). All other manifolds i tried had the turbo facing to the rear and would hit the bulkhead. Mods wise it has a tuned AAZ injector pump and a modified 2.5 turbo, however the intercooler is quite large. Shamefully i admitt that i do not have an egt gauge but will be nagging my brother to be fitting one soon.
TomB : Car had plenty of rust esp under front wings, around shock turrets, fuel tank (replaced for safety) and door sills... a pannelbeater fixed it up as a favour and took 2 years to do so lol
nokivasara : running on and off ... still having interior being done as well as loads of internal body modifications being done by someone who works about 10 hours a week on it lol but on weekends we put a seat in, put the plates off one of our other cars and drive it all day long. No complaints till now.

I know this is a way old thread but nice work with the capri donGTI , I am building a Anglia with sierra td engine , is the aaz pump a direct replacement for the ford one, what did you use for a clutch with all the extra power ;D

I can't wait to see the final result of a restauration! The body looks really badass! Jealous inside... :)
