I was wondering what mods would be required to fit a Td05 from a 95 Saloon to a 95 WRX wagon? Any help is much appreciated.

Also is anybody aware what the benefits of the Andy F modded td are?

Thanks. Gareth.

Am i not correct then in the assumption that the ECU will see the increase in air flow and add an increased quantity of fuel?

Also you seem a knowledgable chap on these sort of questions so can you also tell me....(a brief answer is fine!) why a td05 will give more power than a td04 even if both run at the same boost pressure?!

Thanks.

It depends on the bhp target you have in mind ? If you are aiming for anything under 280bhp then I'd suggest retaining the TD04 to take advantage of the early spool up, a remapped ECU or manual boost controller can maximise the TD04's potential.

Above approx 280bhp the TD05 is running more efficiently and will produce more power for the same boost level. This is due mainly to the reduced exhaust gas backpressure as a result of the larger turbine and more efficient compressor.

The ECU will see the extra air flow and will add fuel up to the limits imposed by your injectors and fuel pump. The ignition timing however may not be optimum for the increased boost as the original car would not be designed to run with the higher airflow rate.

At present the car runs with an AVCR however i can only run 0.9 bar of boost otherwise i hit the fuel cut. Ideas please?

Thanks. Gareth.

Gareth, I'm not aware of the spec of your car.
Do you have any other modifications such as Decat/induction/pump/regulator ?
Your fuel cut seems very low at 0.9 bar ?

sorry for the delayed reply Andy

My car is a wagon with a td04. Decat and induction kit.

I would suggest you don't need a bigger turbo just yet, I recommend you contact David Wallis or Pavlo for a scoobyecu chip which in addition to an improved map will raise your fuel cut level, then reset the AVC-R to a target of 1.2 bar.
