What do you mean by cheap? Cheap as in economic or cheap as in not good?
There was no pic of the crank so I thought maybe you offset ground it to give you the stroke you were looking for. That has been done for ever and works fine. Does require reheat-treating, or maybe hard-chroming the journals. I don't like weld and regrind that some do; have seen cranks and cams fall apart after a while that way.
You would only save money on the crankshaft, the rest of the parts cost the same. Lets not forget the amount of money you will save will depend on who is doing the offset grinding and heat treating, and how much they are charging.

 

Did you use a stroker crank? You haven't posted any pics of it. It would be nice to have a pic of that if you don't mind posting it.

 

The GT3 is running and obviously the engine build is broken in since you're doing 60-130 mph flatout runs.
Can you dyno the car?

\m/

 

We will dyno the car soon. I will let you know the results.

Yes, we used a stroker crankshaft, i will try post some pictures of the crank.

 

wow amazing. Cant wait for dyno results.

 

looks amazing. i think gt3 and gt3 rs are best porsches ever. naturally aspirated is the best. emeginize fikrinize saglık *** ii olmus

 

I had no intention of buying a Porsche, especially a turbo because of my addiction to naturally aspirated engines. But since you guys started this project I was very excited as if it was my car. And today it is. I have been driving it for the past week and it is heavenly. The instant torque of this build is amazing. You guys are really the best at this.

I cannot thank you enough for you work.

Best,

Osman

 

So the red .2GT3 that had the 4.25L build is your car?
Congrats if that's the case.
Can you post a dyno graph to evaluate the power & torque curves?
Any additional pics of the GT3 along with videos of engine revs and drive bys or track video.
Thanks

Thank you M,

Right now the car is under minor styling work. Red color has been changed to Dark Grey as I have wanted an understated look compared to red. As for the videos, the weather right now in Istanbul doesnt allow for extensive testing. As soon as i have updates i ll post them.

Coming from a garage that produces the fastest tiptronic 911 turbos, it may not be as fast as them but as for driving pleasure i can say its motoring nirvana. I ll post the necessary materials to back it up


Cheers,

Osman

 

Yup forgot your winter weather.
Did they shop dyno the car after the build and break-in?
Your GT3 has a unique rear bumper which I really like.
Enjoy that beauty.

I'm sure we are all awaiting further feedback and details in all forms Osman. Please do post some videos when the weather lifts (March?)

Great project.

Cheers
Jay

 

I think the weather will get nicer end of march. We have not dyno the car yet. But our current horsepower expection is around 550 hp (crank). The rear bumper is from 9FF. The rear fenders are not GT3 but from a Turbo for a possible turbo installation.

I have changed the BBS rims to Porsche Center Lock rims. As I want to have a understated look. I ll be in NYC next week, hopefully all the work will be done by then.

Cheers,

 

Great build, and great choice on the new colour.

Keen to see if you really do get to 550 crank HP

 

welcome to the land of turbos you got an amazing car there(thanks to esmotor) , drive safely.

 

Thank you
