Hey guys i need a little help in deciding what motor to put in my project e28. Im not looking for too much speed, whereas between 250hp and 350hp would certainly do the job.So if you guys can help me out with this tricky decision it would make it alot easier for me. Most people i know chose the 745i turbo, but i wanted to check with you guys because this is the home of e28's.
If you have a running M30 car, I would go with a low-medium boost setup TCD kit.
540i swap is a helluva project. It's been done, and to great effect, but it's some work.
745 swap just doesn't seem worth it. Decent results for decent price, but go for the TCD manifold with a modern turbo and you have a much better platform for current and future.
Well i have a m535i low compression motor in really bad condition so i was kinda hoping for a change. Yeah the 745 turbo isnt exactly what i was after anyway. I think its a choice between the turbocharged m30 or the v8. Yes the v8 can be a bit of a hassle but is it worth it in the end?. How much roughly would a good brand turbo cost me for an m30 3.5 and approximately how fast would it be?
How much it costs you depends on many factors. If you buy a kit its ~$4000 to play. If you use 745i parts (which really isn't worth the trouble IMO) it'll be less, say maybe $1500 with an FMU, although Im sure the parts can be had for less. If you can fab and have pretty decent mechanical ability and shop for the right parts (spend money where you need to and save it where used or cheaper parts will work) you could build a very nice system for $2-2500. I have a little less than $2500 tied up in my build and that includes running the car on Megasquirt with all kinds of bells and whitles, so I guess it all just depends.
The v8 swap is only really viable if you can afford the downtime (as is the totaly DIY turbo kit) and have the mechanical ability and tools to do everything yourself.
And the car will be plenty fast with any of the above options. Fast enough that you will start to find out all the other stuff you have to spend money on to make the car cope with all the extra power....
Thanks for that buddy. Putting a 745 or a 540 is not a problem when it comes to money. My father knows exactly what to do as hes done a similar project before and i already have the motors because my father owns a european car factory and i just had trouble choosing which motor i should put and i wouldnt have to pay a cent. I know i shouldve spoken before but i hope that makes it easier for you guys.
If the engines are free and your goals are modest (which they seem to be), the V8 with Motronic swap and maybe some moderate cams would likely be VERY nice for you.
If you want boost instead, the TCDs1 at 10psi puts out around 300hp and boatloads of torque to go with it.
the CSi engine would be killer, but a regular 5ltr would still be so cool. TCD cars would probably out run it, but its NA and theres something cool about that.
Yeah thanks alot guys i think i'll go with the turbo. Just another thing, somebody mentioned above that the turbo is worth roughly $2500, would that be with installation or is there an instillation fee and can anyone fit a turbo or is it hard work?
P.S: If it was between a e39 m5 n a turbo m30 this thread wouldnt have been brought up in the first place coz i know which one i'd prefer
Cheers.
