Just wondering what performance modifications can be recommended for le car??
Currently have manley rods/pistons and vf52 with tune at 155awkw
Looking for ~ 225+ awkw

Do you have any other supporting mods at the moment? Dump etc? Or turbo only? You should be getting 200+ with your current turbo

Dump pipe, 3" exhaust, intercooler, injectors, fuel pump and kido tune on e85, that should get you around 220awkw

The car has had next to everything replaced and an stishortblock due to engine blowing up a month ago but no other supporting mods.

I have been looking for a tbe but so many mixed reviews on every exhaust.
Plus Is it worth getting a frount mount for the slight eztra $$

Has your head studs been upgraded? No point going for more power or especially e85....you may end up lifting the head(s)

Do you mean there were aftermarket forged pistons with different type of piston crown shape/ design?

Do you know your compression ratio at all? And importantly did they use oem Subaru headstuds or aftermarket arp or equivalent ones?

Who built the engine?

All work was completed by techworkz in canberra. The pistons are aftermarket alloy (manley) and maybe im mixing up the piston crowns with headstuds but one or the other was an aftermarket part.

no idea on compression sorry, i really have write down whats been done and get myself a tactrix

A TBE and tune will give you 25% plus , What rpm does your turbo start boosting?

can hear it spooling at 3k and full boost at 3800

what TBE can you recommend? and place to buy

I`m running a 3" TBE that splits into twin 2.5" stainless X force system. The sound is awesome, especially since I fitted a vf52. Its not loud but it is far from quiet. Mine starts to spool at 2750 and at 3000rpm its on. 210wkw Nice tune ,easy to drive 11.8lp100 in the city driving briskly at times.

That is a pretty fantastic spool up time What other supports you got to get that spool up?

I was looking at xforce catback but just unsure of the up/down pipe (ie brand, place to purchase). havnt seen any xforce tbes
Too much stuff for dem rexs and not enough for libs

Spool up is 750rpm higher than the vf46 not really fantastic. Air filter and fuel pump are not much support, but some
I had the original tune and the tbe fitted while the vf46 was in at Pulse racing .

What dump pipe are you running?

VF52 turbo is easily capable of 200+ with the right mods. Headstuds, TMIC, E85 tuned with lots of boost will see 250kW+. I know quite a few MY11-13 WRXs with the same 2.5L donk running 260-270kW with stock VF52s + E85 + big boost.
