The past 2 months have been a busy time with upgrades on the car, I have completely replaced the fuel system including the pump, fuel lines, fuel rail, fuel flex sensor, fuel pressure regulator and injectors. I also fitted a good sized oil cooler in the stock intercooler location. All this a fair bit of work for somebody with my fairly limited capabilities but it all worked out fine in the end and io haven’t blown myself up. My good friend the cookiemonster on this forum helped me along the way, he is a real smart cookie!
The other significant upgrade was the air to water intercooler system. This works a treat and I have been really happy with how it performs.
I also decided to go for a Link G4+ ECU. After I gutted the factory ECU box this slotted straight in with no modifications to wiring etc and it ran pretty well and got me as far as the tuner. It’s a good way to go if you want plug and play without the hassle with wiring or adaptor harness
Next job is to convert the ignition to coil on plug and then the switch over to E85.
The otherwise stock engine and turbo made 173 rwkw. During tuning there was an issue with boost control which I have since established is associated with the boost controller so I need to get a replacement before any more tuning. I’ll hopefully have it all sorted and back on the race track by the end of the month.

I like the 'cooler solution.
 
Its very rewarding to look at this kind of work when you've completed it all yourself, good work.

Yes it was a lot of hard work. I cant take all the credit for the intercooling though, a fabricator did a fair bit of. Wish my skills were that good.

Great work Pat!

There is an extensive build thread for my car here: http://www.mr2australia.com/mr2play/tm.aspx?m=18316

Thanks, Im a shade under 50% of your power output! I do plan to put my built motor in there at some stage.

I would like to see you get up on a surf board Doug!
 
We had a nice winter here this year, plenty of dry days to go track racing. Are you coming to Sydney in early January? You would love the driving and social side of it.

Looks good Pat. I will send up the shroud this week. You should cover all the oil lines with some reflective material if you are still have oil temp issues as they are just about on top of the dump pipe. This may be effecting oil temp management.
Must sound pretty good in the cabin with the intercooler right next to you!

No worries Steve will do.
 
The induction sound is pretty cool. I have set up the intercooler tank in the front with isolation valves either side so i can quickly drain it and replace with 3 litres of ice cold water. Its was 28 degrees at Baskerville last week and it felt like driving a car on a cold night!

Here is a copy of the dyno report from a few weeks back. The power delivery is nice and linear and pretty good for a stock motor but you can see the issue associated with the boost controller. I will be going back for further tuning with a new boost controller and E85.

I had the car tuned again last week. This was back-to-back 98 pump petrol to E85, almost 20% increase in power and torque and around 200rpm gain in spool. Im pretty pleased with the result and was worth all the effort of changing over the fuel system. I'll hopefully be on the track on 15 November to try it out.

Time for an update as there has been a fair bit happening.
 
There has been very little in the way of motorsport since MTC16 due to work/family commitments and some upgrades on the car. I did compete in a hillclimb at Collinsvale near Hobart and won my class. This was my first win of an event on Tasmanian soil so I was pretty pleased with myself, as I had come close before.
 
The trip to MTC in both directions was fairly eventful. When I started the car to roll off the boat in Melbourne it was running like a pig and sounded like an old tractor. I had that sinking feeling as I drove off the boat but by the time the car was on the public road it had warmed up and the noise had disappeared.
 
The rest of the trip was uneventful. At MTC on the first morning the car again ran really bad until it was warmed up. This time though I could watch what was happening in the engine bay. The engine was rocking back and forth like it was running on 3 cylinders and was making a god awful mechanical noise.
 
The next morning I had the mechanics look at it and there was all sorts of talk, such as main bearings etc. Turns out I had an exhaust leak due to a warped exhaust manifold. Obviously the gas flow/pressures in these cars are pretty sensitive. The car behaved flawlessly other than some over heating issues and I made a PB of 1.10.96 on the last day with very tired tyres.
 
Returning back to Hobart I had to drive to Melbourne via Kerang in central Victoria to take care of some personal business. Outside temperature was 40 degrees with no aircon, no floor carpet or insulation, no radio, no cruise, hard suspension and race seat, no tacho and no speedo. When I arrived at Kerang I learned that the ferry from Melbourne had broken from its mooring and had been damaged, the omens were not looking good.
 
I made it to Melbourne the next day and waited for hours to get on the boat. Unfortunately I locked myself out of the car just as the queue was starting to move so I had to smash the passenger window to get in! It was a relief to make it home.
 
Other than the exhaust manifold, the lack of an LSD was starting to really do my head in. With the exhaust manifold, I figured I might as well use the steam pipe manifold I had made years ago, and also fit the GT3071 that I had on the shelf. I also bought a Kaaz LSD and convinced myself that the best thing to do was to drop the engine, fit all the gear (including an ATS inlet manifold) and have a good inspection of the engine and give it a clean up.
 
Predictably, one thing led to another! I ended up getting a third lug added to the water outlet housing (great suggestion by Doug aka falcon) as it was painfully obvious that this would be a good addition. I then proceeded to chase down leaks in the engine cooling system by pressurising the system with air and squirting water mist over all joints and ends to track down leaks. There were lots of little leaks due to perished hoses and rusted fittings. So I ended up cleaning up everything and ordered every hose in the cooling system. As a result I know the system inside out and although it was a pain in the ass most of the time, the process was enjoyable. For anybody racing these cars I would recommend replacing all hoses if they are greater than 10 years old and cleaning of all joints to ensure a good seal between joint and hose. I haven’t fitted the hoses or tested the system yet but will do it soon.

Great update. Congrats on your home soil win, hopefully many more to come.
You'll have to come to SA one day and join us at Mallala for some fun!
