Did you though of an oil cooler??
If so,what adapter plate would you choose? with thermostat,or without?

duke21 · Apr 21, 2014

I do not plan an oil cooler for now. I will try to max out default injectors and if i get 250-60hp i will be happy. You think the oil temp will be an issue?

Lucian189 · Apr 22, 2014

If you will push the car a little in the summer ,and them you will look at oil temp,you will see 100 or more degrees.and the oem senzor is located in the sump,so upper in the engine you will have even more.I wil install an external oil cooler just dont knof if should I use a thermostat or not.I use the car in winter also.

You must install thermostat if you use your car in winter time.

Will be a fun car with all that installed.

Should be approaching 300hp if not get past it (BHP not WHP)

Not sure what the stock fuelling will do though on those CR engines.

duke21 · Apr 22, 2014

i do not plan for now conversion to Bosch. @devonutopia 260bhp thats all i think from stock fuel system, and im afraid how reliable engine can be with 280+ bhp

Okay lets start

My mechanics and i have finally changed all parts and sucessfully started car which is in safe mode now (MAP sensor changed and EGR removed) and waiting to get mapped after full exhaust will be completed. So some photos i would like to share with you all. First, car before modding:

duke21 · May 3, 2014

Intake manfold is down for cleaning and washing in gasoline. I decided to keep flaps:

duke21 · May 3, 2014

Gearbox removed, old DMF and clutch before removing:

duke21 · May 3, 2014

Old turbo GT1749VC and EGR cooler before removing:

Much more space now

duke21 · May 3, 2014

Difference between old GT1749VC and GTB2260VK:

New turbo and manifold:

duke21 · May 3, 2014

Actuator required some adjustment to fit, because it was hitting in firewall.

Exhaust side of turbo needed cutting few milimeters because it was hitting in cilinder head:

duke21 · May 3, 2014

After few hours of adjustments turbo finally fits

Oil return line needed some chemistry too. Original DPF housing was attached just for driving to exhaust workshop.

Look from upside:

Few more pics of new turbo fitted:

duke21 · May 3, 2014

EGR delete pipe instead of valve. ASV retained:

duke21 · May 3, 2014

New DMF:

And Sachs SRE clutch:

duke21 · May 3, 2014

Darkside's alu pipework:

EGR to IC pipe with 4bar MAP from downside:

This one from turbo to IC was hard to join:

But was ok in the end:

Pipework final:

duke21 · May 3, 2014

Removing stock IC:

IC differences:

New one from S3 Audi fitted:

duke21 · May 3, 2014

Dogbone upgrade on both ends. This is Vibratechnics small end replace:

And installed with torque arm insert. This insert caused horrible vibrations in idle so i removed it later.

duke21 · May 3, 2014

Intake is stock for now, but before car is mapped i have to replace restricting intake part which has smaller diameter than compressor's enter:

Nothing happend:

Old parts:

duke21 · May 3, 2014

Full 2.75" exhaust will be installed in few days then i will post new progress.

duke21 · May 8, 2014

Exhaust is installed but its very loud. In neutral sounds like gasoline. Car is in safe mode with error 008825. Can anyone help?

PeeWee · May 9, 2014

You may need to have a tuner set up for EGR delete on the tune.

PeeWee · May 9, 2014

So a little more research shows this as an Air Intake leak but this is a Gasser code. Anyway its worth a look for leaks.

duke21 · May 9, 2014

I resolved it thanks. Vacuum pipes were wrong connected. Thank you all. Car has around 260hp and absolutely flies. I'm happier then ever
