Turbo Bmw 325i
 

Ok so I'm going to help my friend turbo his 1995 Bmw 325i.
The list I have made consists of:

Garrett 60-1 T3/T4E .63 or.82(would .82 be to big for a 2.5 liter 6 cylinder?)
Tial .7 bar 40mm wg or 1.3 Bar 46mm wg(which would be safer?)
Tial Bov
Greddy Profec E or profec B BC (depending on how much he wants to spend)
CCA intercooler
Homemade Manifold
Homemade DP and CP
and maybe bigger injectors
Would this setup be reliable if tuned properly?Is there anythng you recomend?Anything I missed?Thanks.

figure out the fuel issues first, that's what I would suggest.

injectors, management, fuel pump..

Re:Turbo Bmw 325i
 

fueln and ignition management first...If you really want to use the potential of that turbo.

Re:Turbo Bmw 325i
 

would the .82 be to big?

Re:Turbo Bmw 325i
 

My personal opinion is that .82 is huge!!!
BImmer heads flow damn good but I think that's a long shot

On my friends M car he can barely spool by 3500 and .90 and that's not that much bigger

Good luck though my dad and I want to turbo his 98M3 but the thought of blowing one of those engines i don't even want to think about!

Re:Turbo Bmw 325i
 

there was a thread about 2 months back covering turbo bmws.. some good info in it, do a search for it.

Re:Turbo Bmw 325i
 

3500 rpm ain't that bad...wel depends on the rev limiter though...I don't think they rev to 8K like the B16 or b18C's
If they rev to atleast 7K I would use the bigger turbine for a later spool if you are conserned about fuel economy.

Re:Turbo Bmw 325i
 

yea my friend has an m3 also but he doesnt even wanna take the chance of blowing it up

Re:Turbo Bmw 325i
 

Build it properly from the beginning, good engine management and low compression, map it right and there's no chance you'll blow it up.

Re:Turbo Bmw 325i
 

With the 2.5 M50 engine, a .63AR will be full boost by 3500. Not sure what that .80AR will do for you. Also, youll need a chip and injectors. You can use mustang injectors, thats what im using. PM me if you need any help. Ive been thru this already.

PS. Your making the manifold? send me pics

Re:Turbo Bmw 325i
 

wat year mustang?

Re:Turbo Bmw 325i
 

'86-95 GT injectors - 24# or 30# will work great for turbo

Re:Turbo Bmw 325i
 

Since the charm of BMWs is the handling, I doubt this car is going to see alot of straight line action. Or at least I wouldn't reccomend it. While .80 a/r would be fine for a drag car i'd reccomend .63 a/r for a road car; my friend has a t3/t4 .63 a/r on his 2.5 liter Impreza. It's only a 4 cylinder though. It spools very quickly. I too am interested to see how this turns out. Mostly the fuel management. Those things have sensors everywhere. :P

I think my friend Josh is doing this same thing right now. I will see if I can get him on here. :)

Re:Turbo Bmw 325i
 

yea my friendly is definetly not into going straight and he takes full use of the suspension so well use the .63, that is if he coughs up the money otherwise goin to scavenge the junkyard haha
