4000RPM for peak boost/power/torque?

I personally think a VF34/P20 is a bit small for a built 2.5 litre.

GTPS01/02 for a worked 2.5 seems to go alright.

Yeah thats what I thought as well as I was considering the VF34/P20 on my EJ257. But went for the twin entry HKS GT2835 which currently hits full boost (1.5bar) @3300RPM, I do admit that I miss the response of the VF35 (1.5bar@2600~rpm) but it just runs out of puff too quick on a 2.5.

The TMIC will be your limit i reckon if you've done everything else. Get a nice big TMIC with a decent scoop and waterspray and you're in business.

Other than that, get a FMIC and accept a few hundred RPM's lag.

I'm sure B4GT's beast is a 2.0L not 2.5...

Yeah i want the FMIC but im bone dry ATM. Got a wedding to go to in Europe so the TMIC is the best for now untill next year when the flow will be coming in.

Definitely....why bother building a 2.5 if you not going to throw a decent sized turbo in it eg. TD06+

Ahh, i shouldn't have made the assumption he was looking for more power in his police spec 06 in the avatar

Would be funny having that on the dyno, oohh the irony.

Hah thanks chee. Ok Roller bearing is the vf22.

I was thinking of going to p20 housing but Sean said for the current application the p18 was fine. P20 will add lag specially on a 2ltr because being a bigger exhaust housing, it will require more exhaust to spin the wheel. Upside more torque i spose.
