I have finally managed to get the Liberty dyno tuned. It is an EJ25 that has been fitted with new diesel sleeves, has been fully closed deck, is using STI heads, cams and inlet, 440cc yellow tops, TD04, WAIC, 3" mandrel and Microtech LT8s.

It was dynoed with the 29's on in 4th gear. It showed 170hp ATW (128kw) with 5.5-6psi of boost. The figure sounds a little low but considering the tyre size and minimal boost I am happy with it so far. Torque was excellent at 348NM and it came in very early in the rev range. It seems to be a very good base map to work with.

Once I get the IC sorted out (this one was blocked with mud) and the new turbo with 15 psi it should show well over 200 ATW.

I did a quick calculation with tyre sizes/gearing. If it had been running standard size tyres it would have been 198Hp ATW. Bloody good for 6psi.

The torque is awesome when driving it. 1500rpm and feed it in 3rd and it pulls very nicely. Can't wait to get more boost and better intercooling happening.

NIce work i am glade that you are happy with the results and with more mods on the way this thing shouldbe a real weapon.

My standard RS with 17psi showed 177hp atw on the same dyno just so you know.

I didn't know that. So it must be going ok then hey.

Very nice work Brett, can't wait to see your final results.

We just got a TDO5 in at work Brett, you should still get full boost at 2k rpm with it and the thing will still make good mid to top end.

I think I have already mentioned that having a TDO4 on a 2.5 is a crime.

I think he needs two turbos
And a stash of gearboxes

Definately a stash of gearboxes . . . damn that's some grunt in a Subaru done up as a fourby.

Al, I am looking for a VF24 for it. I would go a VF37 if I could find one at the right price.

I may go to a VF23 but I think the power range would be further up the rev range than what I am wanting.

The fuel economy is a lot better than the 20l/100 that it was getting. Todays effort returned 12.8l/100 with most of that highway driving. A bit more refining in the IC/turbo - boost area and another tune should see it the way I am wanting it.

What about a VF35, 15 exhaust housing with massive compressor. Just what you want.
Common as too, fitted to 01 on Aus STi's.

You got any up there? What are they worth?

Wanna buy a mint TD04?

I drove the WRX's down teh coast again yesterday. They have swapped the turbos from VF23's down to VF24's and they feel like they spool quite quickly in comparison.

Rexnet is the place to get a VF35. 35 is like the non homemade version of Grants 10/12 hybrid.

24 has an 18 exh housing, 23 has a 20 housing.

Ill attest to that the WRX's seemed very seamless in thier power delivery with no real boost rush, but you gotta love those 6 speed boxes.
