OMG's Personal S54 Build :)

[GThomas]

so fancy.

Couldn't agree more haha.

[nando]

it's a work of art! :)

[dude8383]

Made some more progress last night... Head is on :)

[nando]

S54 throttles are way too big for an S52 - you're not going to make 275whp with them either. Also, the ports are the wrong shape.

Also, this is way OT. :p

NOPE.

2.5K for ITB setup really doesn't matter once you're so deep.
I have the S54 airbox and throttles from my collection of bits on the shelf, Tune and management debateable...

I dont give a shit about velocity stacks looks. That extra HP TQ and throttle response, Mainly induction noise with that factory air box will be nice.

But after it blows, S54 will be next.

Stock S54 290WHP Modded S50/2 275 WHP

Rod bearings, Vanos, Oil pump woodruff key, maybe a new balancer on a 100K motor and you should be good quite a bit more reliable.

I just really want to know the clearance of the E32 735 booster vs E90

I've never seen a reliable street us spec s50, s52 Putting 275 hp to the wheels. A euro one would do it easily, but those cost more then a whole s54 swap. If you have a "recipe for a 275 whp s52 I'd happily take it. I really want build one of those, but I just don't think it's possible, or economical.

I believe the E90 booster is narrower and slightly taller which makes it appealing for those of us going with the S54... That plenum is huge!

Isn't the 735 booster the same as the ix? I have an ix and e90 booster I can compare if that helps?

You are correct. I am curious to see how the E90 booster works with the E30. First time hearing about this...

Looks like a little indentation still between cylinders. Seems like most need at least .005 removed.

Want to do S50 with ITBS, so eyeing the E90 booster setup.

ITB's on the S50 doesn't seem worth it to me. I wanted to go that route but the cost of doing so makes an S54 that much more attractive.

Nice build! Those new Vanos tabs are really nice looking, glad somebody got that solved.
Someday soon, I will start working on mine again. :)

Yeh when I saw VAC release that I was like... done and done. The cryo treated stuff was just looney bin money. This is a nice solution thats affordable and won't cause me any greif later on.

Watching this! I hope I can give you more info on the E90 booster soon.

:D Sounds good man. We can keep tabs on each other haha.

Is it really economical to do a itb s50 swap, when compared to a s54 which already has em? Itbs cost 2-2.5k if you buy em for the m5x. I've been researching this pretty heavily recently. Because I really want velocity stacks.
