2.5Si engine
Hey all,
I am a new member. I read the forum for some time now and just made my account. I have read the newbie guide. I will post pics and signatures whithin the week.
First of all I have to say I love the community
I am an owner of a 2007 Sterling grey Z4 2.0. I got this car as it had a lot of extraw from the previous owner. (M heated seats, xenon, 17 factory rims, 10 speaker etc). However I am a lot dissapointed by the 150hp the engine provides.
I would like to ask. Can I fit a 2.5Si engine in my car? Do I need to do any alterations? Anyone has done smthing like that? Cost? (Or any power up for the 2.0 engine which is good)
Thank you in Advance.

I believe that buying just the engine is cheaper than a whole new car. A used engine.

Fitting it and getting it to work properly won't be. Buy a new car.

It is possible to turbocharge the 2litre engine, there is a thread on here about it.Z4SpPD wrote:Hey all,

Re: 2.5Si engine
Do consider selling or Part exchanging your 2.0 litre for a 3.0i or a 2.5si it will be the best way to get more performance.
I had a 2.0 litre before my 3.0 and enjoyed the smaller engine but it does need to be revved and used in the high rev range to get the best out of it. I used to mostly drive my Zed 2.0 in 2nd 3rd and 4th when out on the back lanes of Northumberland - that way it was fun.
Unless you are a mechanic and have garage equipment I wouldn't start messing about changing engines - Just make the move to a 6 cylinder.

What you could do is raid your car for goodies before you sell it for a better engined car.

Re: 2.5Si engine
It is a great car. I have it 7 months now. However my previous car was a mini cooper works 220 hp. I was used to the power especially on the highwayRorybeanbutler wrote:Why dont you give yourself a bit of time with the car. Have you had it long? You could fall in love with her.

Re: 2.5Si engine
I am no expert on these things but surely even if you swap for a bigger engine wont the brakes, exhaust and other components be completely different. We are talking here about going from a four pot to a six pot.

Re: 2.5Si engine
As said I would get rid of the 2.0 and start again. Do your homework before parting with the dosh. There is no substitute for a six pot,period

Re: 2.5Si engine
What made you think going from 220 to 150 was a good idea!
