Question Motor Swap NEED HELP: Used Long Block Engine M30 E24 3.5Liter

I own a 1986 325 no "e" or "i". I recently drove through a flood and killed my motor. I plan on on putting the m30 3.5liter e24 motor from a older model 635 in. The motor i have now only goes up to 5000 rpms and I dont want to put a beastly motor in just to be restricted by my current computer settings. Is there a chip I can buy to fix this? Is there anyway to put a 635 racing chip into my computer now? I dont know what to do. Somebody please help me out.

When you do the swap you need to use the 635s computer and engine harness. Then just swap gauge faces, I don't know if you really should be doing a swap...

+1, if you thought using the same computer of a 325 would work on a 635 motor, dont take anything out by yourself, not trying to be an ass, but at least ask more questions before u do anything.

if you didnt even know that you have to use that cars ecu i highly recomend you junk the car and move on. a motor swap is WAY out of your league. motor swap is MLB .. your still playing t-ball.

Stop discouraging him. If you think changing an engine is major league then you are still minor league.
It's an all nuts and bolts swap, well documented.
If he has tools and can follow instructions he can do it.

Yes, it is all nuts and bolts. If it is the same engine, but he is not putting the same engine in. I never said he can't, I just said maybe he should not do it.

If it is his main ride, NO. Project yes! How will he ever learn if he does not try? I just think he should read up before tearing out.

And what else is harder then changing an engine? Well there was this one time I did a turbine swap... The only thing harder is performance building in the engine.

my old man always used to tell me "its all nuts and bolts" whenever I couldn't figure something out on my car as a kid. Ha I'm glad to see someone else say it.

ive been thinking about it recently about swaps and stuff, and when you really think about it, its just like a big ass mechano set. who has one of those? time space and tools are all you need to do anything.

Well I was gonna get the parts off of ebay because I'm having trouble finding a car. The plan was to get a motor off of Bavarian Auto Recycling and have it shipped to me for around 800 in all and hopefully turn my beat up 325 into more of a beast I just don't know where to start. Either way I need a new motor because it got flooded out.

There are plenty derelict 535 and 735s out there. You can buy a complete running car for less than the cost of a mystery motor from a recycler. You will have all the components you wil need that way and be able to sell off a bunch of other stuff.
Unless you know exactly what you will need a complete donor car is the answer.
