I can get a 1.9d for peanuts that has only done 100k, i'd like this to be the base for a side project of mine.

I'm thinking of fitting a K14 (that im removing from my tdi anyway)
TD/TDi oil feed pipe and housing
mod the sump/block for an oil return
AAZ complete pump (what's the optimal timing on one of these?)
Rover Boost pin
custom FMIC with 2" pipes
TDI Crank sprocket and new bolt

Any help or input is appriciated!

why ford injectors?

I hear they fit and are an upgrade?

Standard td injectors and nozzles should give all the fuel you can use. The big part is having a IP set up correctly to push the fuel you want.
Do you have the part number for the fuel pump?
Be careful about pushing more then stock boost on a original non turbo engine. You will need to keep the egt's a bit lower to preserve the pistons and the exhaust valves.

You will also need to modify the oil filter flange / cooler for a turbo oil supply line. You could pull one from a td engine.

I think I'll just get the pump from an AAZ that's laying around.

Im fitting the turbo, Oil filter flange and oil lines from my TDi

the N/a diesel's are exactly the same as the AAZ, sodium filled valves and piston oil squirters i believe.

I'm putting a FMIC on there too.

The only worry is the best way to drill and tap the oil return into the block, Is it really that simple or do i need to start pulling the sump ect?

Cheers

i was reading over daves 200hp build the last couple days, and bigger injectors do not make more power for our cars. his 200hp was with a 9mm pump and stock 1.6 injectors mercedes nozzles actually made less power with it.

if its not a turbo engine factory, its not set up like one. i believe they dont have oil squirters like there turbo brothers. and i dunno if a TDI filter flange will fit, but i could be wrong. and the non turbo engines dont have sodium valves. we have broken enough of those bastards to know what there made of, lol.

I'm talking about A 1Y 1.9d, this engine never made it across the pond.

TurboJ · « **Reply #8 on:** March 22, 2009, 02:11:31 pm »

The 1Y is a great base for a performance engine.

For example, the rods look much beefier than on the AAZ (no actual test data on this, but they are really beefy to look at, I-profile style).

The 1Y has oil squirters, a well-flowing (in 8V terms) head and very good manifolds. I would take a 1Y any day over an AAZ.

About injectors, at 280 hp you still don't need upgrades

I'll forget the injectors then! What should i do for the oil return?

so we can turbo a 1Y and look for power with the same confidence than with a AAZ?

it does have smaller wrist pins than an aaz

TurboJ · « **Reply #12 on:** March 22, 2009, 03:24:09 pm »

Many people use 1Ys on their high-power applications, over 250 hp in some cases, and so far I haven't heard one go bust. Looking at the internals, there should be no reason why it couldn't take just as much load as an AAZ. And those manifolds really are hugely better than AAZ ones.
The rods are sturdy, pistons have as much meat as AAZ ones, and those wrist pins don't seem to be a problem.

In fact, for my Evo 2 engine build that will inevitably follow at some point in the future, I would take the 1Y to start with.

I actually sent him a set of newly rebuilt 1.9 dual stage injectors with the merc nozzles in them. The merc nozzles did actually deliver more fuel, but I think the dual stage setup on the injectors may have hindered the upper rpm / high boost power output. If they were in a set of standard 1.6td injector bodies I think they would have performed better. That being said, Giles has said that he does not think that the stock injectors are a limiting factor in going for the bigger power output.

as far as I know, I am the only one to use the Mondeo injectors, I fitted them not because they are better but because I knew that set was almost new (compared to my 400k+ 25yrs old set).
idle quality improved immediately, my old set was really busted, instead of having to wait for a rebuild I used the mondeos.
so far they work but I'm going to fit a rebuilt GTD set in there.
