525tds turbo kit onto 325??
was in scrappy and was thinking of it.Saw a 525tds which seems to have same e/m as an e30 325.Would the whole system be a cheap conversion for an e30 325.I was planning on throwing it on my drift car as i dont really care if it blows up :mad: .be a nice project without presure..ie if it dont work out then so what :D

So basically does the manifold turbo and piping and inlet fit??? could always change the turbo and add intercooler afterwords

just being curious really,,,no imediate plans
unfinished m50 in drive and exams are making sure of that :roll:

the manifold can be modified to fit, but its alot of work and takes too long to be honest...

I think the turbo will be a problem because of the differences between temperature with petrol and diesel.

But you can buy them cheap enough of ebay

Once upon a time, turbo makers used alloys for the diesel turbine housings which weren't as resistant to heat as petrol turbine housings.

Typically the exhaust of a petrol engine will be higher than a diesel so as long as the two types of turbo and fuel weren't mixed up it wasn't a problem.

However, some manufacturers of diesel turbos use much more heat resistant alloys in this day'n'age so they've become more suited to use on petrol engines :D
