Ok, I have been working to add a turbo to the car for an age now, and finally I have the parts - well most of them. Everything is coming in, all I h... Show moreave left to do is the intercooler and the downpipe exhaust.
Turbo is a Garrett GT2560R (AKA the GT28), with a Bell Engineering manifold - the new one. See the pictures here. Show Less
Ok, so building from the previous pages, I have decided to do a hybrid between the Track Dog Racing install for the compressor to interco... Show moreoler side and the more traditional installation on the intercooler to intake manifold side.
The intercooler that I am using is an old Mitsubishi Starion one that was donated by TPSRetard - thanks guy!.
After much looking and examining I decided that I did not want to go to the lengths of the install that TDR suggest - lowering and moving backwards the radiator and A/C condenser, cutting the cross member between the headlights, and lots of other things. I did not mind cutting the hood, and thought that I could get a fit with that.
Here is where I thought I would have to cut to allow the pipe from the compressor to go over the radiator and down to the intercooler - - and here is where it is going to go down - . This is the area that first cut, and found that it was just a little bit too short - . Here is the final cut that fits - .
Other issues were that the A/C condenser (pump?) needed to be bent out of the way a bit, so with a bit of a push and bend I moved the bottom of the pot towards the front and right side of the car.
The intercooler will have to have the ends changed slightly. On the right side (looking towards the front of the car) the end cap on the intercooler will have to have the out-pipe at the bottom and side, and on the left side pointing upwards.
Brackets will be made up to attach to the bolt point that the front tow hooks were attached to.
While I was at it I made a cover to keep the air flowing through the radiators - Show Less
This is the top of the downpipe that I designed and had made. Unfortunately it was made up pointing towards the outside rather than the inside o... Show moref the car, so when on the turbo we had to bang the heck out of it to get it to fit. It will be re made so that the exaust will all hook up.
Here are some views looking at the (simple) cross over that I have made. This will all go once I move to put in the intercooler.... 12 PSI! Until then, just 6.
Here is a view of the exhaust side of the turbo.
Here are some early pics of the exhaust setup...

First Issue: No maps for turbo with stock injectors. Rumor has it that the stock injectors will run out of steam at the top end, we shall see. To get the car to run after putting on the turbo and setting TURBO 1 default settings I had to increase the Master Fuel (z1) from 100 to 153.
Changes that need to be made to the TURBO 1 defaults.
1. Change the injector offset slope (Z825) from 100 to 200
2. Change the Injector Offset (z830) from 030 to 000
3. Change the Prime Factor (z715) from 120 to 160
Changes 1 and 2 - which are the settings from the NA 1.8L map should bring the injectors back into spec and allow me to reduce the master fuel back to 100. Change 3 is to prevent the spark detonation on key on that is occurring because of a leaky injector.
Items left to do:
Heat wrap the exhaust
Heat protect the rubber and other pipes Show Less
