Is the above worth the hassel and cost.

Ive a my93 wrx import with the following mods and wondered it if would get rid of some of my lag.

I know it can be done with my manifold or i would be better gettin a sti v3 1.5 manifold?


apexi power fc & commander
twin dump decat downpipe
Blitz Nur spec RX exhaust system
STI alloy header tank with blitz cap
apexi intake system
550cc injectors with carl davey adaptors
FMIC
exedy organic clutch
AP lightened flywheel
walbro 255 fuel pump
Map sensor
SX Fuel Pressure regulator running 3 bar
andy forrest 20g turbo
oil catch can

 

is lag or spool-up the problem?

 

Better to be done to your existing manifold or a spare

I have pics of one done (mine) and can give you dimensions if needed?

I also have a spare phase 1 manifold if you need it to convert whilst keeping your car on the road?

The Phase 1 manifold would have to be ideally switched so the TB is welded to the front side and the existing would be blanked of.

With the version 3 sti manifold you can just rotate this and remove the dowels from the underside so they don’t foul the inlet pipe no other work is needed to the manifold its self.


If its lag you trying to cure i would not bother with the above but rather go with a good top mount intercooler.

 

i am planning a 2.5 conversion in the future but that is a few years off i think so ideally i want to keep the FMIC and was just looking for something short term.

So reversing the manifold isnt worth it then even if i bought i sti v3 one?
