Hello Members,
I always dreamt of building a setup just like BemDub in an E30.
Am currently building / swapping an s38 motor into my e30 chassis. Its fully refreshed motor top to bottom. I built the manifold by myself which was a fun experience as well as help from the Legend Gunni to have it running and tuned properly remotely.
Could anyone advice what Diff to use on this build as the original diff from the e34 was a 3.91 and currently on the e30 chassis its 3.71.
Would the gears by shorter or longer on the current Diff 3.71
Here is a detailed list of the build
71mm T4 turbo
Tubular manifold with turbosmart 38mm wastegate
Siemens 630cc injectors
Walbro 340lph intank and bosch 044 external pump
Vems 3.6 ecu
Aem water meth
List goes on.
Photos please! I've got an E34 M5 that I am turboing at the moment (final stages) so I'm interested!
I would say get a lower number diff to make it longer (more top speed) because its a very light car with a strong strong engine
20comer,
Bit ashamed to ask lool but I'm having a hard time posting pics, how does one upload pics ?
No shame. I use https://postimages.org/pt/ to host the images. They provide a number different links to display the images. You just copy that link into the new message box and click preview. Try that until you find the type of link most suited.
Anyway, Im sure there are smarter ways of doing it...
