Hi,

the first time that a turbocharger hit my specifications

http://www.turbodriven.com/en/performan ... s/efr.aspx

- Twin Entry
- Ball Bearing
- Titan Internals

other nice specs

- Boost Controll Selenoid on Turbo
- BOV on Turbo
- optional Speed Sensor

time to source out the correct specs for my engine :)

They look like very high spec turbos with lots of gucci controls.

I keep getting cheesed off with their turbo selection calc page :-(

They're all the rage on MKIVsupra.com after people have been suffering some issues with Garrett. Worth a hunt about for some background over there

Hi,

i have no HP goal, my target is 500NM in a whide range with a rpm limit of 8000rpm

as i can't can read compressor and turbine maps my feeling say that the smaller EFR-6758 can hit my target, looks like you can read them, what would you advise?

background infos are fine, but i think these series turbo have the release in 2011

fullrace can also give some infos

http://www.full-race.com/

■Toyota 3SGTE - Twinscroll External WG only **Exisitng Twinscroll bottom mount**

existing weinscroll mount...? external WG only...?
i definitely will use a internal gated turbo, will a T4 twin entry flange really fit the toyota twin entry flange...?

Hi folks,

who is able to read compressor and turbine maps???

meanwhile i think the 6758 (44lb/min) or the 6258 (49lb/min) both in twin entry spec will fit.....
[CT20B = 33lb/min]

http://www.full-race.com/store/turbos/b ... turbo.html

http://www.full-race.com/store/turbos/b ... turbo.html

the issue is that i want to choose the smallest possible turbo, the targets are
- quick spool up
- boost up to 8000rpm
- 500NM in a whide range

Diceman, i have no boost target as boost is just necessary evil for me, or in other words as low as possible

Aaron from Full Race explained it simple

When these turbos are matched correctly to the engine they will spool quicker than anything else on the market


hope he is in right :)
