2,5 Tunning

[Z4SpPD]

Can the 2,5 engine be tunned? (without supercharging etc...)
To what extend?

Cheers

in a word, no.

I had my facelift 2.5i remapped (was 177bhp to start with) made a cock hair of difference.

The M54 (192BHP) is pretty highly strung from the factory so without forced induction your pissing in the wind.

Diff suspension and brakes are money better spent.

isn't the e89 204 bhp?

 

[jamie_z4]

Yeah, it might even be 217bhp which was what i had in my 325i e92. This is the same engine i had in the E85 Z4 with 177bhp. the 204/217bhp have a different inlet manifold on so , as per the M54, it is pretty much at its peak already.

So the real question is...

if I move on from my 2.0 e85... (I would like more power, terrific car but...)
Should I go for the 6pot 2,5 204 bhp
or the 2,0 turbo 240bhp?

Is the 2,5 "slow" as the 2,0 due to weight?

Confused... :|

I've had my 2.5 for a couple of months now, and although it's not a fast car it's not slow either (0-60 in 6.6 secs). It depends what you want from the car?

The 6 cylinders do sound great when you give it some beans though!

You could get the 2litre turbo & map it to almost 300bhp if you want power

id go for the 2.0 4 pot turbo - the 23i is a bit lacklusture in terms of performance, especially coming from a 2.0i E85, you wont notice much performance difference, due to the extra weight

Just IMO of course!
