this has prob already been discussed but i just wanna find out this: if i stik a VF34 on a my98 wrx wid mild mods will i notice the power difference even if i have stock ecu managment? like will ther be an increase in power or will it come once i get a ecu?


thanks

you'll get alot more benefits with an aftermarket ecu, wont get the full potential without it.

i run a vf28 with stock ecu n just a safc, but had the vf28 in b4 the safc. I still noticed a big difference over the td04, but yeah, youll get alot more out of it with a aftermarket computer.

did ya install yaself?

nah RMS did it.

when i sold my car (my99) i pulled my autronics out leaving in the VF23, the car had similar top end power but was laggy as hell with the factory ecu.

may i ask why u want to change yur turbo before the basic mods.
i want to knw because i was in the same position not long ago.

well i got the exaust, FMIC, CAI, Boost controller so yer. its alright how it is but i want a little more lag and more pull :P

they aren't hard to install if you do it yourself. I got someone to do it the first time but then i did it myself the second time. Might as well save some money. I installed vf35 on my 95 wrx and ran ok without tune or anything but i didn't thrash it cause was a bit worried about it not getting enough fuel early

why would you want more lag?

cause he wants more pull, but yeah like its said go for an ECU 1st, even if its not a MOTEC/ECUTEK just get one thats in the middle ground, also try get it 2nd hand.
