Turbo upgrade on impreza

[Subaru786]

I am getting a used engine for a subaru impreza turbo 2000,1999. As I am getting my engine changed i will be upgrading my turbo to a vf 28 turbo and an STI top mount intercooler, my question is would it run fine without a map am i able to drive it as normal or do i HAVE to get a map?

The person putting the engine in says it is fine and does not NEED  a map any views and help.

It will need a map, and if you're changing the engine it'll be a waste of money if you melt it....

I'd be a bit concerned if they're suggesting it doesn't need a map for a bigger turbo. With a turbo and intercooler swap it will have to be mapped. Also with the engine swap are you fitting the same injectors?

Unless he is changing the Ecu then you need to map

take it else where, they are clueless

[Subaru786]

Yes i will be keeping the same injectors. The mechanic says he has done them before and they drive fine without a map. A map is only

if you want the most gains out of it otherwise it will still drive.

Abit clueless but still sourcing a good engine for good value.

He's totaly clueless mate, walk away and find a proper specialist. after those change its will need a map, no 'to get the best gains', it will need mapping to stop it from self destructing.
