2.5 upgrade, does it is worth it ???
I need to repair the motor of my E30 M3. I want to go with the 2.5lt upgrade. Do you think that it is worth it pay so much $$$ for it, compared with the gain, or you understand that it is more practical to just repair my current motor?? Iused my car on a daily basis.
What you think?
1988 Henna Red M3
I'm facing the same delimma & would like
some input too. It'll be tempting "while you're in there" but I can see the costs rapidly escalating. Suggestions?
if you got the money why are you asking?
This is not the issue, does it is worth it?
I have a 1989 Turbo, and performance is not the issue. M3 e30 are cars with a special suspension which are the envy of any high performance car, but spending 5-6 thousand in an overhaul with a gain of only 60 HP, is to be considered????
I'm going to Knob Creek & may want to
spend the money on another machine gun
Re: 2.5 upgrade, does it is worth it ???
I finished my 2.5 last summer and have put 1900 miles on it so far. If you do it right, it is well worth it to me. The new motor ROCKS! VAC stage 3 head with stock valves, cams, 2.5 kit etc. For all required components expect to spend 7-10k to do it yourself(assembly) add 2.5k for somebody else to put it together. However, it puts a ridiculous grin on my face whenever I rip it sideways. It is all good to me.
here is a video of modified 2.5l
video here (WMV format)
on that setup gearing is as follows:
1st gear goes to 45 mph
2nd gear 67 mph
3rd gear 94 mph
5th gear rev limited at about 162 mph @ 8500 rpm
If it is within your means.......
I've always said that if my motor ever goes, I will do the 2.5 upgrade. I know turner has a basic kit for about $2500. As long as you don't get to crazy, I think you could maybe get every thing you need for the bottem end, and leave the top as is. Maybe just add bigger injectors. Of course, these things do have a way of getting out of hand. If I had the money....

Corrajem3, you know what you have to do here. Rebuild the engine to 2.3 or 2.5L( my choice) and add it an Alpha-N system with the CF plenum to wake-up those ponnies. Enjoy the life!
