Z4 fitment - Tips ?
Howdy ho,
Got a Z4 a couple of weeks ago, birthday tomorrow so the mrs won't let me fit it till tomorrow . I understand the battery should be disconnected, and the ECU unit is located under the passenger seat (94 WRX Import). Does anyone have any tips or advice for fitting this ? Will i really feel the difference ? .
Thanks beforehand for any help provided.

It really is straightforward to fit mate, I'd do an ecu reset as soon as you put it on your car though in case there's any error codes stored on the z4.

I noticed a big difference when i put one in my 93 ra, a lot smoother running and more boost.

Z4 ECU
Hi there,
Just got offered a Z4 ECU off a 95 WRX, claiming Boost to 16PSI. I currently have a WRX Wagon Import. Now i Dont know much as im new to this whole thing, but am i right in saying that the Wagons mapping is set to boost higher or earlier that the saloon ? do any of you guys know if this replacement ECU would be beneficial or even work " safely " on an early 94 WRX ( as it was mapped for a 95, is there much difference? )
Cheers

Right, so the saloon is actually set higher on boost anyway ?. Is the Wagon on a TD04 as opposed to a TD05 ?
Can anyone advise me what i can do to acheive the best performance from the Wagon ? is it possible to take over 300BHP without turbo upgrades ect ?
Cheers for the advice !!

Anyone thinking of adding a Z4 onto their saloon i can highly reccomend it. Much much smoother power delivery and you can feel the difference when accelerating.

The TD04 will only allow about 280BHP max.
The best mod would be to get a 2nd hand TD05 and a Z4 ECU. This would take a standard WRX wagon from 220ps to 260ps straight away.

Cheers Scott,
Any ideas what i would exepect to pay for a TD05 second hand ? and what size of compressor would be better suited I.E 16G / 18G ..20 far too expensive !! lol.. for the mo anyhow.
Will the Stock internals fuel pump ect handle this OK or will i need to upgrade ?

16G can be picked up nice and cheap (about £120 - £150). Fuel pump could be changed dependant on mileage. If it's done a few then probably worth changing.
The standard 380cc Injectors will get to to just over 300BHP.
At this stage you are reaching the limit on injectors and TMIC. So they would be the best things to upgrade if you want much more then 300BHP.
Internals should be fine if mapped well....

Cheers Scott, much appreiciated .. ill have a butchers for a 16G then.. are the 440cc injectors the better ones to go for if you intend to keep modding.. i dont know how much over 300BHP it will go after the TD05 is fitted ? .. sorry for my stupidity but what is the TMIC.. im really new to this !! lol

I personally would go for extra headroom with the 550's considering the TD05-16G is capable of flowing enough air to reach ~350hp in std form especially if you plan to keep on modding
