Kev's Turbo Fuel Injected Engine Build (Update 14/12/14)
Hi all,
Firstly this is not going to be a full on engine build thread with everything written or photographed as there is lots of those type threads already
on the internet if you do a search. It's more a quick overview of the process with photos telling most of the story.
Link here to previous parts
that arrived since last year.
Quick list of recent main parts (Supplied by Rod Penrose) :
CB Performance Aluminium Case
Pauter Roller Rockers
Scat Wedge mated Crank, Flywheel and Gland nut
Scat 'H' Beam Rod
Scat Chromoly Head Studs
AA 92mm thick wall cylinders
AA Forged (really) pistons to suit
CB Mini Wedge Port heads
Engle TCS 20 cam and Followers
Most of the fuel injection stuff is from the 'VW Speed Shop' in Great Britian. ECU, wiring, coils and sensors from the USA.
This long process started around November 2013 when I pulled the motor out of my car that I had intended to convert to turbo, injected etc. After
pulling the engine down and inspecting, it did not have the internals that I was told it had when I purchased it as a completed running motor. The
parts were good for what it was, but not for what I am planning on doing. I then had months to wait for some of my parts to arrive from the good old
US of A.
This is just a mock up of the Turbo exhaust to see how it fits and to make sure the Turbo was going to clear my rear valance before I pulled old motor
out.
Parts finally arrived and the long preparation process of blueprinting the engine begins.
The engine case havles themselves need modifications. The oil pump pickup hole is misaligned and as were the main journal oil supply holes. The black
texta lines are indicating where the actual bearing oil groove lies. Both needed porting to match up.
A modification to the Cam followers allowing more oil to pass through and up to the rocker gear. This aids in lubrication, but also aids in increased
cooling of the heads.
The camshaft needs to be clearanced in 8 positions to stop the conrod big ends hitting it due to larger crank stroke.
Camshaft bolts also need clearancing to make sure they dont kiss the oil pump.
Checking the cam lift to make sure it is the same as the supplied information card.
Bolted top half of case on and checked cam shaft and crank shaft end floats. And about to check deck height to see what I have to start with.
Obviously way to much, but needed to work out how much material I need to remove to obtain the desired compression (deck height).
Then time for cleanup so as the assembly process can begin.
Although this doesn't show a time line, there is a lot of work involved to getting the engine case and components to this stage. This actually took
me weeks to here as only working on it here and there. Beginning of the assembly process. Also as going full flow from the oil pump, need to fit
threaded plugs into case and oil pump.
Case halves finally together, oil pump fitted.
Then started fitting a few of the external accessories. Deep sump, oil cooler adaptor, crank angle sensor parts.
Added an extra external oil cooler to the car.
Checking ring clearance and adjusting to suit. Case savers and barrels (no pistons) fitted to engine case as mockup to check head stud bolt lengths.
As you can see here, the head bolts are to long and all need to be shortened.
All rings fitted back onto pistons and pistons fitted into barrels. Then barrels and pistons fitted to engine.
As of today, heads now bolted on for last time with new pushrod tubes and seals.
Just sat rockers on quickly to see how they look and I love it.
As I said, this engine build process has taken me about 2 months working on it when I can. If you ever have anyone build you a half decent motor and
ask why it cost so much, I can vouch there is a lot of work involved and more then I had realised.
I will continue to update over time and when new things are added or changed. Hope this hasn't been too much in one post and bored people.
Cheers, Kev

Looking good mate, did you set up rocker geometry before you buttoned everything up? Otherwise you run the risk of wiping the cam lube off

Good job mate, just finished similar project with CB magna fuel and spark. It is a lot of work. What injection? Maybe I missed it.
Good luck with it all.

Nice going, Kev.....nothing much more to do - looks like we'll see the car at Wakefield Park on Saturday, then ? 
I'd rather wear a Beetle out by racing it than by polishing it!

Thanks Todd, Pete and others.
This was just setting up geomertry for the roller rockers. Half lift and then set adjustable pushrod so as rod is inline with rocker adjusting
stud.
Have done a little more, fitted up tinware and carbies for breakin test run on stand. Hopefully by early next week I will fire her up, all depends on
family commitments this weekend.

Had all the chromoly pushrod tubes cut (machined) to length. The machine shop rang and offered to fit all the tips for me, but I asked them not to.
Look at all the metal shavings that came out of them. Imagine if this went through your engine or blocked the oil supply through the pushrods and you
had no oil getting to the rockers.
Now that I finally had my pushrods back I could install them and finally fit up my new lovely roller rockers. Look at this photo, can you see the new
problem that arose.
That's right, now there is no way my standard steel vw rocker covers are going to fit with those long cam lock down nuts. They are actually made for
bolt on rocker covers. And to add to this, the bigger (thicker) rockers also touch on full lift at pushrod end.
But guess what, I have a spare pair of alloy bolt on covers here and those nuts are still to long. Take the nuts back off again and have them
machined down 5.5mm (more delays) so I can finally get some covers to fit on there.
As you can see above, getting very close to start up. Wired up coil, tacho etc. Just need to get a oil pressure switch and some fuel line, add oil
and fire her up.
But I feel this has been the easy part getting to here. I think wiring in heaps of wires to the ECU, throttle position sensor, air temp sensor, crank
angle sensor, cam angle sensor, oxygen sensor, head temp sensor, map sensor, 4 x coils, 4 x injectors, water pump for intercooler (radiator for this
still to be fitted) and whatever else I have forgotten will be the harder part.
But I will get there, eventually 
Kev
P.S. I would like to also say another thank you to Rod Penrose for his assistance. I needed to borrow a couple of things to assist the engine build
and more so I could get to this stage (exhaust) and he was more than willing to help
P.S.S. Also to AUSSIE_MICK for lending me the tacho. If I don't say it, he might have a bit of a whinge

Nice work Kev thanx for posting, takes time and effort to do so,
but makes for a much needed "go to read" here.
Neat wiring takes a lot longer than you would think, so be patient.

Hi all,
it's alive - YEAH 
As I said, I have the engine set up on a stand and started it up today. Still just using carbies, distirbutor and different exhaust for the break in
period.
These videos don't give a true sound at all, it sounds very crisp and I am very happy with it. I think it does sound better in this first clip than
the second one.

I'm pretty sure I will be running a muffler, as I think it will be to loud for my liking without one. Although I must say, they sound hot without one
but that DB level is more for drag strip I think.
Time will tell
