No it isn't, there's quite a lot of differences.

I recommend this book for bedtime reading. HOW TO Tune AND Modify Bosch Fuel Injection BY BEN Watson Paperback 1992 0879385707 | eBay

And this Haynes manual, not any of the others. This one has specific 16v information in it.

Look on Amazon, probably save some money.

There are 2 fuel pumps on the 16V, a lift pump in the tank and the main one outside the tank. Next to that is the fuel filter and accumulator.

The States is the best place to look for most parts. They had lots of 16Vs there.

Australia isn't the most likely place to find one.

The 8 valve also has two pumps. One lift and one main.

The main difference is the metering head I think. All other bits should be interchangeable.

Is the pump priming when you ignition on or stall?

If the lift pump dies, you will kill the main pump. Ask me how I know. Camden Gti apparently changed the lift pump, but didn't, and I was charged with a new pump plus fitting. I then had to buy an actual new lift pump and a main pump as they both crapped themselves.

Recently when I thought my main pump died, it turned out to be the fuel pump relay.

Gti imports in dural can get the parts in.

You can bolt in the injectors and other hardware for sure but that's not the whole story. 8V K-jet cars are pretty thin on the ground even in the UK as they were dropped in late 87 in favour of digifant.

My advice is don't re-invent the wheel, buy the correct parts.

Read the manual and the Bosch book, then fixing it will be easy.

Failed hall senders in the distributor are pretty common too. Often it starts out dying when hot but seems good from cold. Then it'll fail sooner and sooner until it doesn't start at all. The hall sender can be replaced, jaycar sold one for under $20, not sure if they still do?

K-jet runs at a higher pressure than the digifant, so the fuel pumps are not interchangeable. You get high speed fueling problems.

Actually all parts were changed. Then you were unhappy and waited a year and a half to complain and threw away all the parts. Makes it kind of hard to assist you at that point.

16v and 8v Kjet run different pressures. Like gavin says the states is a good source for parts. Try techtonics tuning.

Is that like giving it a tune up and then having to wait close to 5 hours while you sorted out why I had no power and why my brakes were squealing which resulted in me no longer having disc backing plates, you having to rub down my pads and still having to come back to you to try and tube my k-jet when I dropped it off it was all fine? You even mentioned in a previous post that it was a hoot to drive, yet when I collected it it wouldn't rev past 4k, wouldn't go over 60kph and squealed like a banshee as anyone that was there can attest to?

Did you buy the Helios blue one for sale in Adelaide a few weeks back??

That's my cars twin!!

I had a similar issue with mine, I sourced all the parts OS.
Ill find out exactly where I got what soon for you
