S65 vs LSX Dimensional Difference

Hi,

I was talking to a shop to see if I could swap an LS motor into my E90. It's an N52 in there now.

Aside from the wiring which they said they wouldn't even consider touching they said that the width between the frame rails is 28 inches and that an LS would need 30 inches at minimum.

With all these little cars running LS engines I wondered how this could be that it wouldn't fit. I am wondering what the dimensional differences are with the S65 and LSX. Does anyone have any data on the S65 whereby I could use it for comparison?

Why don't you just buy a Z06 and save half what you are going to spend and headaches.

Not sure about the E90, but my buddy just swapped an LS with a single turbo into an E46 325 sedan...... Fit just fine! He is making 1000HP on pump gas with it.

LS's are cheap to swap, parts are dirt cheap and ready available. I am quite sure you could do the swap and make it run for 10-15K including the engine. Making the cabin electronics work would be difficult though...... Nothing that custom gauges a harness and a bit of time wouldn't fix though!

  • I want a 4 door that handles well and has strong power
  • My car is pretty well paid off
  • I don't have the budget for a vette all at once
  • I'd like to do something that others can benefit from as well

The main issue that most people are afraid of is the ECM integration with the sensors and gauges. Do you have info on how your friend did that?

Fair enough.
It's been done plenty of times in the E36 body style.
If you look on bimmerforums.com
You will find lots of info, you can reach out to the fab shops and etc to sort out the witting harness and etc.
look under engine swap !!

Good luck !

Run your present ECU as the body computer & run a stand alone for the engine controls.I have seen that done in a E39 with an LS3.

I think that is a gOod place to develop this conversation. I have seen all the swaps in other models and I have been contacting shops to get pricing and feedback thus this thread. I want to find the specific issues and try to plan how to deal with them.

This was my idea exactly. I am just having a hard time finding someone competent to take on the work. I want to really compare engine block dimensions. Tons of LSx specs but nothing to compare on the s65.

Ask this guy to measure the dimensions for you.

I believe an LSx would sit in there just perfectly. If there is enough room for S65, there is definitely more than enough room for an LS.
