Bigger turbo on Lpt engine

Post by Japedo »

I have a 15g turbo and fuel injectors out of a 95 850t with low millage on the shelf.
Can i swap these on my 2003 v70awd 2.5t? I realize i will require a tune, or mbc to see any real gains.

But if u were in my situation with the parts available, would the swap even be worth it? Would the downpipe on a 03 2.5 bolt to the older turbo?
This car is new to us, but runs great, pcv system is in good order, zero oil leaks and has decent power for a stock lpt. But i kind of want to mod this car a bit, the 01 xc it replaced stayed stock for the 6 years we had it. But this car shifts smooth and wants a mild tune atleast im thinking :)

Thanks in advance to anyone with an opinion on modding a lpt.

the downpipe from a LPT wont fit on the larger size turbo. You will have to custom build the downpipe.

Okay, well i do have a downpipe from a 2.3 t5. I could cut and paste that into my existing exhaust.

But im not familiar with these lpt engines. Is the higher compression ratio that these engines have a limiting factor in how high they can be boosted?

Thanks

The rods are the same as far as I know however I believe the cylinder walls might not be as thick as neccessary for the extra compression, probably need to change injectors, and exhaust as well as tune.

Right on, ill do some more research. The 13g turbo it has currently adjusted to make 11 or 12 psi via a ecu tune, and bigger injectors may be all the tune i need. Just an extra 30 or 40 hp would make me smile :)

Thanks for the input osman
