Well since some folk have expressed a bit of interest about my A4 build, I thought I would take the time to share it with you lot. Now I've been messing about with it for years so knowing where to start and the correct sequence of events is going to be challenging! So here goes.
I bought the car years ago, it was a completely standard 1.8T Quattro Sport, 1 owner & full service history, it was in pretty good condition and served its purpose very well.
This is how it started out.
It wasn't long before I got that itch to do something to make it scary, it was drastically under powered and driving it flat out just didn't do it for me. So after numerous hours of research I realised to make it mental would require some serious work, at this point I did consider a skyline, supra, RX7, S4, RS4 etc but that was too easy and would eventually modify that anyway so off I went! Bought an engine in bits off eBay for £60.
Swiftly acid dipped it, painted it & bored her out to 83mm + a hefty 4.5 thou clearance!!!!!
I opted to drop a 92.8mm crank in there to take up the total displacement to 2008cc, the donor crank was taken from a 2.0 8V golf engine, dropped it right in there. It took hours of die grinding to provide enough clearance for the crank to rotate but after millions of hours I finally got there and was satisfied there was sufficient clearance.
TIGHT!!!!
Notched the bores to allow the Integrated Engineering rods enough room to do there thing.
And finally I managed to assemble the motor with some nice shiny bits and the actually fit & rotated! I can't tell you how long this took. I settled on JE's with an 8.5:1 CR
Now this is all based on an early 1.8T engine (058) so uses an internemdiate shaft to drive the oil pump. There quite horrendous from the factory as well as the gear being too fat to run the crank I selected, so there was only one thing for it! Grind it back
Put in the centres of a lathe it wobbles like a fat kid, so off to the machine shop to have the taper removed and grind the gear back.
Happy days! With some ARP crank main studs & rod bolts Job's a good'an.
Another thing I found during my research was that the timing wheel bolts have a nasty habit of backing out. At high RPM I can only guess it makes a bit of a mess! So in an attempt to avoid that I decided to tack weld the bolts into the crank.
That just about covers off the bottom end, any questions just fire away.
So with the bottom end figured out, lets move onto the head. That started out the same way as the block, bit nasty.
So dipped it & lick of paint to tart it up
Assembled with new exhaust valve guides, the inlets were bob on, nitrided stainless inlets & inconel exhaust valves & a high lift spring kit with titanium retainers all supplied by supertech. There was some light port work carried out, just to clear the casting mismatch etc and smoooooooth things out. The stock cams were dropped back in for now.
Happy days.
And my parting picture for tonight is K03 Vs. Garrett GT30R with a kinetic motorsport ported compressor housing.
To be continued........

It was still standard power then!
.....
is that true
And as you've mentioned it chews through everything! I bought some fittings, mostly adaptors from Earls, I get them at massively discounted prices through work, the AN fittings from Torques on eBay and the hose from him also, I'm told its the same as Earls Pro lite 350 but much much cheaper. Its stood the test of time so far.
Everything came in three seperate large consignments to keep the shipping down. I was also scouring the internet for failed / incomplete projects being sold off. I found alot of expensive parts unused and alot cheaper than new, saved me a fortune. I also have a few mates that have some good contacts as well, people never believe me when I tell them what I put the car together for. I also did all the work myself, machining was done by a mate so only cost a slab of beer
