After 9years and 15,000 track kms, loving the NA , I couldnt handle another frustrating track day of "ordinary" high powered cars taking me down the straight at Eastern Creek. Time to go turbo.

Setup
Motec M84 - Tuned, Supplied and Fitted by Phil Armour Motorsport Penrith NSW.
Thanks Phil for working hard to create a great tune. Also for working long hours to get my car ready. Immaculate workshop and professional motorsport business.
Sensors (motec or compatable)- Lambda, Air temp, Fuel Pressure, Water temp, Oil pressure, Boost Control.
Turbo EVO10 - Thanks to Chris at Wollongong Auto Supplies.
Engine - Stock Cultus - 11.5:1 compression
Exhaust Manifold made by me. steampipe bends, twin chamber style.
3" dump
3" exhaust straight through
Cultus reverse manifold
Nissan SR20 throttle body
E85 fuel
Custom Fuel rail
ID1000 injectors
460LPH Fuel Pump
Turbosmart wastegate 7psi spring
Oil Cooler
PWR intercooler
2" pipes from intercooler to plenum
Turbosmart blowoff valve
Fuellab Fuel Regulator
Lightened Flywheel + 4 puk clutch

Tune is
1st gear 7psi
2nd gear 9psi
3rd gear 11 psi
4th gear 12-14psi
5th gear 12-14psi

Results are shown below: I am very happy with the tune. Phil Armour held boost back as engine is old and its a good starting point.

Im planning to build a new engine soon. That will be time to maximise the power.

Thanks to Zuboo for freely sharing his setup experiences. He gave me the confidence to venture into a turbo setup.

Decide on what Turbo to use.

After years of google reading and learning about turbos and compressor maps etc. The turbo choice wasnt exactly calculated or mathematically verified.

Its was a seat of the pants choice that was dictated by circumstance.

I was in Crisbys shop one day.

I selected an EVO10 turbo - Why? (when your ready to get married you do, no other reason)

Because I said to crisby I was thinking about turboing the swift Crisby said

" I reckon an evo10 would suit the gti for what you want to do with it. And there are plenty of turbo parts available. And I've got a new one thats done about 500km that you can have for $500. And its twin scroll. I reckon is will spool up at about 3500rpm, it will be perfect for your track driving."

As it turns out Crisby has totally ass'd it and was 100%! :roll:

The tuner is of the opinion the EVO10 turbo and final setup is perfectly matched to my engine setup. (ie This doesnt mean it will work for everybody who wants to run a turbo)

Thanks Crisby - Wollongong Auto Supplies.

Got a shock when he gave it to me. Its got a huge exhaust flange on it. Got to fit this huge thing onto the engine is a small space and fit a twin pipe manifold between ie 1and4, 2and3 manifold.

More info to come.

3" exhaust straight through for lowest backpressure possible. Compliments of some highly skilled work colleagues.

Its quieter than the NA with its 2 mufflers.

It would be quieter than the NA setup with just one muffler. Advantage of the turbo setup is the turbo's impeller is in the airstream and helps muffle as well.

I did 2 track days.

Car was fast however the front end had really bad (dangerous) torque steer.

Gearbox was sounding a bit ordinary after 2 days so I stopped.

The engine was really good. It was like cracking a whip when I touched the accelerator.

No lag, instant power from about 4000 to 8500. We set up boost by throttle percentage so the power was really manageable.

Parked the car after 2 days and embarked on fitting a honda euro gearbox. Did a lot of work but didnt finish it.

Car is now for sale in pieces.

Motec and harness is sold.

Shell with cage is for sale.
