Engine Cutting Out Really Bad

[4doorsFTW]

Hi there I'm new to this forum and. New to skylines in general.

I own a 4 door R33 gts turbo currently when I accelerate while the car changes gears the engine cuts out really badly to the point if I take my foot off the accelerator the car stalls/cuts out completely

Any info on this would be greatly appreciated.

Oh the car is an auto if that helps

Cheers

More info required, non-factory mods for starters (BOV etc).

Auto feel like it's slipping?

I don't know if it's stock or not but it has a Garrett T04E T3/T4 turbo, a turbo smart boost tee that goes to a wastegate. The auto feels fine doesn't seem to be slipping.

After that I don't know if there is any other aftermarket stuff I bought it off a family friend who got the car for a debt someone had to him

Got the car from debt... so he's a drug dealer or something? Either way seems like knows nothing about cars and has sold you a lemon..

[4doorsFTW]

actually he is a tow company owner that lent out money to a friend haha.

The body is straight, engine runs perfect apart from the cut out between gears,

rego'ed

REVS checked out, so its not stolen or financed.

and i bought it for 2 grand

so

Sounds like Turbo seals? Does the car blow smoke when changing gears? Otherwise it could be anything like BOV, Vac Leak...

Not that I can notice. I asked about the history of the car and got a hold of the old owner who had it since 2001 when he imported it from Japan as a n/a rb25de which he turbocharged not long before he handed it over to the friend I got it off, now he said it wasn't tuned after he turbo'ed it, would that be doing it?

After it revs high it cuts out not just as it changes gears. Only just noticed only had the car a week haha

Sorry, I'm new to turbo's just got my full license.
