Turbo Question

[bmwrp8]

Guys Im planning to install a turbo kit for my 525i m20 A/T...my question is If I install turbo would it break my engine i have 260,000kms on it.And I have automatic tranny, would it break if I install turbo on my car? Some of my friends say that putting a turbo in an automatic would kill the tranny do you guys think this is true?tnx.

No way, never. He's asking about dropping it in an auto The question is how much can the slushbox handle?

[Macv]

Thats what's been covered already....

People have bitched and argued about the auto tranny being-able/not-able to handle the extra power.

Here we go.... I was refering to this...

Down the page it mentions...

5HP30 tranny are very robust... even the V12 BMW engine uses this tranny... not to mention Rolls Royce too that has 500HP engine.

And

he told me the 5hp30 was overkill in the 540i/a. it's like having the allison tranny in a truck. this tranny was used in:
austin martin DB7 ( 5.9 liters, V12, 420 hp, 400 ft-lbs. )
Bentley Arnage (6.8 liters, V8, 400 hp, 619 ft-lbs)
Rolls-Royce Silver Seraph (5.4 liters, V12, 322 hp, 361 ft-lbs)

i got the car list from a 5hp30 pdf from zf's web site & i got the car specs from edmunds.com .

But I guess we arent talking about the 5hp30... so none of this matters.

It's a 4hp22, pretty stout when fresh.
Heaping abuse in the form of boost on a 260k driveline is like asking grandpa to move pianos. He'll try and with difficulty succeed for a short period before he expires.
