If you stayed 205/207 it could rev to 8.5k would turbo still be making power that high up in rpm? If so then you'd probably have a bigger power band on 2.0

Here are my calculations...

Maxed out tune, reving to 7k rpm....
http://www.turbodriven.com//performa...6_wrsin=92044&

Maxed out tune, reving to 9k rpm....
http://www.turbodriven.com//performa...6_wrsin=92044&

Spinning out to 9k certainly could be an option on a 2.0L...

something looks off with how low the torque is dropping off way to much

Looks right to me...its a VE/pumping issue. The turbo can only push so much air, and the pressure ratio across the motor takes a real nose dive. It'd probably be a shade better up top with a larger turbine housing, but the turbo looks fairly well matched....

Minor detour from the turbo kit....


Header and uppipe are done. They are also wrapped, but I didn't get a pic of that yet...


I made some steady and solid progress yesterday.
1) Ran new crackcase ventilation lines.
2) Made block off plate for the 2011 STi TMIC recirc valve flange.
3) Drilled intake for NPT weld bungs.
4) Ported out uppipe
5) Replaced broken sway bar end link.
6) Bolted motor back in.
7) Wrapped header and uppipe
8) Picked up Brembos.

All in a 1/2 day's time...lol....

Meth injection? 1, 2 or 4 nozzles?

Looks good!

Sorry, no, just vac connections for bcs, purge, and crankcase vent....

This car has been on E85 for 3 years and I'm not looking back. No need for meth injection....

On the home stretch. Oil supply fittings are shipped (ordered them in November, I don't know what takes so long). Ran the turbo coolant lines last night. Milled .040 off the power steering line fitting to make it fit right.

Fitted the header and uppipe. I used this "Gasket Eliminator" stuff from SPA. I don't know if I like it. Its a putty thats hard to apply, and squeezed out of the flange (and I assume into the pipe). I think I'm going to take it back apart because I don't want that stuff going into the turbine. Probably will just go with the standard copper rtv...

^I have the proper ts gasket, but it is used. I hate paying $5 shipping for a $8 part...lol

The gasket eliminator stuff looked interesting so I figured I would give it a try....

Fab'd up the IC brackets last night. I'll have to get pics in the next couple of days. Hope to have this thing on the road this weekend.

Dangerously close to firing this thing up...



Need to double check everything, finish up some work on the downpipe, and reflash....then its time to start...

Interesting piping work. (Not harassing the welds)

How long do you plan on running w/ this setup on stock motor.
I hope you get to drive er this weekend!

^Probably until it shows some sort of failure. There are varying opinions of what these motors can take. I personally want to know the limits.

Glad you find the pipe work interesting The EFR is a tough fit. Or perhaps you don't like the pie cut methods. Its the cheapest / easiest method to prototype something....

I think your welds look pretty decent! I hope you post a clip of this thing when it fires up and then maybe one of it ripping through a gear or two

Thank you. I have to give my buddy Joe (Precisioncustom on nasioc) the credit for most of the welding you see in these pictures. I've done all of the bracket work and some of the stainless tubing, but he has done all of the aluminum and the tough pipe work. When I run out of talent, he fills in...

Can I hint that if you have the time, go back and regap the rings on the factory cast pistons...hint hint

I say this as you don't seem to mind turning a wrench and it'll extend that engine's life.

No I wasn't making funny well the doc, I was just intrigued by how you managed to fit the efr in there. Very creative to say the least, because these are some long turbo that's for sure

Awesome, thanks for the tip. I honestly won't do it, but I'm in the process of understanding the specifics of these engines, and your input is respected. You know your way around these engines far better than I.

What do you gap your rings at if not to factory spec? Do you go looser I assume?

I figured you weren't. Its a hard fit. I had to be very careful with placement. Fitting a Garrett is way easier, but then you have to deal with the gates. I really wanted one of the smaller frame models (6758), but then they scrapped the TS IWG launch on those....
