It's cool, but to me that's more of a chassis swap. When you move all the wiring and everything related to it to a new car, that's not so much what I call an 'engine swap'. Still really cool to see the engine sitting in the bay, but if that's what it takes to make this work I'd rather just keep my e30 an e30 and put an s54 in 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.
I am a pursit now.

Chassis swap aside...the n55 swap is perfection. Light and can make more power than the s54 with just a tune. Some nut will pave the way for a e30 swap with proper management.~ Puch Cafe. ~ Do business? feedback ~ Check out my leather company ~

N54 weighs in at 430lbs so the N55 is roughly 385lbs and the N20 is 304lbs~ Puch Cafe. ~ Do business? feedback ~ Check out my leather company ~

They integrate the turbo housing;
Both turbochargers and exhaust manifolds of a n54 probably don't weight much more than 50 lbs.
I've had a set at my place- I'm sure someone has a set hanging out and can just weigh them.
As for power both are great; N54 makes over 450rwhp on stock turbochargers and fuel with downpipes and a boost up / remap
As far as the age old twin vs single turbo debate. ...
Oem twins is killer. I've had the same engine (2JZ) in NA, single turbo, twin turbo.
Parallel Twin turbo is the best all round powerbandOBD1 M54/M52TU swap as a M50b25

N55 is the better engine over the N54, has a better power band, less lag and better economically.
Speculating vs their info you're just shooting from the hip.
That is why supra guys ditch two turbos in favor for a larger single turbo.~ Puch Cafe. ~ Do business? feedback ~ Check out my leather company ~

But we all know the real winner here.... N52>>>

Also info on the twin scroll power band vs the laggy twin turbo setup. That is why BMW went to a twin scroll/single turbo. Proven to make the same power with just a single turbo and twin scroll and proven to make a ton of power with a turbo upgrade and running stock management with a tune for the larger components.

****I had a pair of n54 twin turbos and exhaust manifolds on my shelf;
the total weight was not much more than 50 lbs for it all.***
The N54 turbines are very trick; extremely light weight compared to a 2JZ-GTE twin turbo setup
***(the 2j had traditional Iron cast manifold and bolt on iron cast turbochargers; the 2jz-GTE oem setup was about 80 lbs - I purchased 4x used sets to get 1x good pair of twins)***
N54 turbines with integrated hot sides
You can see that the exhaust manifold is actually tubular welded steel with a engineered heat shield
in 2009 I had a car with a 2JZ engine; this is the engine famous in MK4 supra Twin Turbo.
I drove it daily with both Twin turbo and Single turbo; I liked twin turbo (parallel) more than the large single.Last edited by Wanganstyle; 03-05-2014, 03:19 PM.OBD1 M54/M52TU swap as a M50b25
