Just how much of a performance advantage does an S54 provide over an S50 in an E30? The S54 is clearly a more complicated install not to mention more $$. The rated power differential between the 2 engines is not all that big. I want to get bigger power but wonder if the S50 is "good enough" without the need to go S54.

Where is KL? If you're in the US or outside Europe then S54 all the way as it would at least be possible to buy parts for it.For all things 24v, check out Markert Motorworks!Originally posted by mbonanniI hate modded emtree, I hate modded cawrz, I hate jdm, I hate swag, I hate stanceyolokids, I hate bags (on cars), I hate stuff that is slowz, I hate tires.

Well the e30 cluster doesn't go to 8, so that's an issue. You can use a e30 m3 cluster but people want crazy money for them. For now I'm just putting a small shift light in mine until I can afford an AIM dash. s54's are cheaper than s50b32's over here, so it's a no-brainer.- '88 m54 coupe

People use regular E30 Clusters with the S54 as far as I know. The speedometer is off of the sensor in the diff, the fuel level is off the float in the tank, the tach gets the same input through the harness and I'm assuming that you still have the same type of coolant temp sensor for the cluster as the older 24 valve motors.For all things 24v, check out Markert Motorworks!Originally posted by mbonanniI hate modded emtree, I hate modded cawrz, I hate jdm, I hate swag, I hate stanceyolokids, I hate bags (on cars), I hate stuff that is slowz, I hate tires.

thats not a hard and fast rule as my parents S50B32 has about 60k miles on it and it is very strong yet many S54 for sale have more mileage.
still if i was going to go to all the trouble itd be an S54 without question between the two. S38B38 seems to have most potential though as far as the 6's go89 E30 325is Lachs Silber - currently M20B31, M20B33 in the works, stroked to the hilt...

S50 parts are expensive and hard to source. if you're in the states, stick to the S54. The cost between the two swaps won't be significantly different, but you get a newer motor, newer electronics, and more parts availability.
I'm using an E46 M3 cluster in mine but the conversion isn't even a little bit simple. I've been working on it since 2011.. lol

engine for engine price the s50b32 is cheaper, but will be a bitch to get over "apparently" im looking for the s50b32 personally.----WHY and the parts will probably "get me", but ill have the shipper send over extra parts that tend to go. hell idk sometimes you just have to wing it.hell idk sometimes you just have to wing it.

I have to say that I really love the noise that the S50B32 makes. It is also a very simple swap once you solve the brewing issue. The S54 requires a lot more electronic support to run, which is a downer.
All that said, if I were buying today, I would go S54.2006 GMC Sierra 2500HD 4WD LBZ/Allison
