is this a good way to go?
 
hey guys i have a 1990 520I and im looking to turbo it over the winter along with paint and some other things, i am wondering if the turbo (somewhat) kit is a good buy to build off of. also what else will i need? i will be adding intercooler not sure of demensions of it but for now just wondering about the turbo (somewhat) kit.

S52/S54 swap and you are done.

captain E34 05-03-2012 06:30 PM

Really? Just swap it out and it will be better then the turbo? Will it mount up the same and will it mount up to my getrag 260 tranny?

captain E34 05-04-2012 09:40 AM

Would it be better tp purchase a 540? Like mid 90's?

What motor is in the 520?

captain E34 05-04-2012 01:28 PM

m50b20 150hp i would like to make it atleast 200hp, i could just swap for an m30, wit 208hp but i like that its the original euro engine not found in canada or the states, and the feul consumption on an m30 is rediculous!!

I'm not sure if the manifold is the same as the b25. If not, you'll have a really hard time tracking down a manifold for it, likely needing a custom one made. Be prepared for loads of work, learning and unexpected turns with a turbo.

Why not swap a m50b25 in? Probably a straight swap, close to 200hp.

Well the link on my first post shows a basic kit that includes a turbo exhaust header also a turbo and partial install kit, i believe ill need an intercooler and intake, also low comp pistons and short connecting rods to get a lower comp. ratio

captain E34 05-04-2012 02:29 PM

If im gunna do all that new injectors and higher pressure fuel pump is in order, i wanna stay away from engine swaps, but like if its my only choice then ill just pick up a 540i later in life

You certainly don't need to open the bottom end. Heck, you probably don't even need to remove the head. Low comp pistons, etc, or not necessary at all for a 200hp goal.

You'll need:
-manifold
-turbo
-oil feed
-oil return
-intercooler + piping
-bov / wastegast
-exhaust (downpipe, merge into exhaust)
-fuel injectors
-engine management
-loads of time

Pretty much it really.

captain E34 05-04-2012 08:00 PM

Thats all i want pretty much, and that seems completly doable! Is the turbo kit i posted a good way to go?

captain E34 05-10-2012 02:23 PM

so the onlything i need to find now are the fuel injectors, where would i look for those? and what size or pressure should i get?

Kamil 09-19-2012 08:49 AM

would the 2.8L injectors work for a setup like this or for my 323ci?
