lol
rossco it would be 13.5 or thereabouts from memory stock (not the RA), but having the dual stage its on 10 low/ 14 high still. the RA runs about 16 stock i think yea? |

V2 Sti is .7 bar (10psi) stock (v2 sti closed deck engine ran 8.5:1 compression & td05).
V2 sti ecu boost cuts at 1.05 bar just like the RS ecu. RA ran same engine & 13.5 psi.

hmmm seems ive been misinformed then as i thought the v2 was 13.5 stock and the RA was 15.5 ~ 16psi stock, both running 380 injectors. was there a major difference in the timing and fuel maps between the sti and the sti RA, as i see youve owned one youd be the one to ask...

Boost was low because they ran the bigger TD05 turbos. v2 sti 260 HP (195kw). v2 RA 275 Hp (205kw). (at the flywheel) You'd only need a small amount of additional boost to make that difference, the main changes between the two are the fact that the RA is basically a stripped out lightweight shell.

compare a torque curve between them, the RA carried power for much longer into its range.

Thanks Stace ^^
I haven't seen anything comparing the two and have only read the 'official' Subaru spec's.

To hell with it, cheapest boost fix, just weld that worthless damn waste flapper shut!! Then you can save weight and money on all the extra bits the ECU thinks it needs.

ok ross, so iv got the boost control solenoid hooked back up (no more shitty boost tee). i run the stock air box with a silicone air intake and 3" zorst. so stock boost with those minor mods, should that be ok without an after market ecu ? shorly the 16bit ecu has some learning capabilities ?

the stock ecu has some tolerance for environmental influences, thats about it.
practically all modifications unless tuned for with an aftermarket ECU will result in poor fuel economy or potential damage to the engine.
