Is this the stock turbo?

[m1tch]

Well the turbo is quite large as stock, but small for a rotary, check the photo that I posted with the 3 turbos, from left to right:

Greddy T88 - 1000bhp piston engine, 600bhp rotary engine
OEM FC3S turbo - Probably 400bhp piston engine, 280-300bhp rotary engine
OEM T25 from a Z32 - Probably 250ish bhp, would run 1 per rotor on a rotary

Rotaries need larger turbos due to the extra combustion cycles it has over piston engines per rev, so a large turbo for a piston engine, is a medium sized turbo for a rotary.

I would need a GT45 to max my 13b out lol and a GT60 to max out a 2.6 litre quad rotor

the fuel pump is receiving 13V even at idling and that indicates it might got a aftermarket fuel pump? will give that a check soon as well tho.

This does not mean you have a aftermarket pump its just that someone has obviously done the fuel pump wiring mod to achieve 13v which is quite impressive, that will give you more fuel flow for sure.

The only way to check is to open the lid and see whats attached.  With stock injectors then there would have been no need to upgrade.  It will still be good enough for the BHP its capable off and especially with 13v even with the 880cc injectors.  Thats only FD fueling size wise, although the FD pump apparently is a little bigger.
