        Nice, yours is the first limited edition M3 with a S38B38 I've seen or heard of.

        18"s with a 3.25lsd, I'll bet that does very well on the highway. I'd love a 3.8 both for the extra power and not having a distributer cap in the way of a normal radiator but hard to obtain in the US.

        How does your stock booster fit? Is the engine off center towards the passenger side an inch?

        Wheels/Tires: 18" Style 32, front - Yokohama ParadaSpec2 225/35R18, back- 255/35R18 (no grip problems here ;))
        Exhaust: Custom dual 2.5" stainless,
        Purpose: DailyDriver - summertime
        Biggest personal swap hurdles: engine mounts,

        as for the cooling system I went the easy route and fitted the biggest possible radiator up front that I could find fit when I did the swap in April '11, was suppose to fabricate the front end and fit a bigger one this winter so that the electric fan wouldn't do all/most of the work, but long story short, the time is/was un-sufficient,

        Future Plans: plans for the engine bay would be a new air filter, thinking Simota CF(GruppeM looking thing) + I'm thinking of painting the coolant tank's top half black? .. and I'd like a brake upgrade ...

        not in US but I hope it's O.K to post some euro trash in here? ;)

          The S38's airbox is very thick, so thick in fact that you can grind it so that it fits perfectly around/over the booster :up:, have never heard of this before but my dad who had done this swap before in the early 90's before it was "common", experimented and figured that one out back then ;)

            No way! How many mm did you shave off? Any pics of the airbox alone or before the booster went in? I wish I had a spare to mess with first.

              Regretfully I didn't take many pics of the swap in progress , and none of the airbox alone ... I could take you a crappy pic of how it looks as it sits but you wouldn't see much..

              Having a spare would be nice for you to have for a first time ;) but if you're careful you will be able to do it... just don't take too much, little at a time,
              It is pretty safe but taking too much wouldn't be nice ;)

              I don't have any spec on how much was shaven off either .. as I said , I just didn't document this swap as much as I now would have wanted too =(

              EDIT: you just shave the edge off so that it "floats" with the booster , going around it ...

                Those motors look right at home in E30 M3s

                  basically looks like a S14 + 2 cylinders :up:

                    It is, but the other way around. S14 = S38 - 2 cylinders. I heard it is called the s14 because it took just 14 days for M Gmbh to design it (lop two cylinders off the s38b35), which as we all know was originally the M88 in the M1. The s38b35 in the M3 would have been too heavy for DTM for which the M3 was designed. I read that they would have put the s38 in the street M3 but would have been too expensive, and probably too extreme at the time. So Hartge and Alpina were the only ones to offer it since their buyers had deeper pockets. Hartge went with the biggest engine available at the time which was the s38b35 for the H35-24 while Alpina used the M30B35 in the B6 3.5S.

                    Bottom line is that yes, these motors are right at home in E30 M3s. That is why the s38 is such a great swap- its period correct, originates from the M1, is the s14's big brother, and over 300hp.

                            It is euro e28 m5 intake. I built this e30 m3 in 1998. I cloned H35 24 m3.
