What will limit me first? V3 STI Remap
Hi All,
My V3 STI GF8 is getting an Andy Carr ESL remap at Autotecnica next month and I wanted to see what people's thoughts were on my spec and what might be easy upgrades to give me more performance from the remap. I plan to go MAFless. Engine wise I currently have;
-EJ207 2 litre shortblock, V3 STI Heads
-Harvey Trick Up-pipe
-Samco turbo inlet pipe
-Forge Recirculating DV
-Walbro 255 to be installed
-Standard VF23 Turbo
-Standard Yellow injectors (believe these are 440cc)
-Standard air box with Cosworth panel filter
-3in sports catted exhaust to be installed
I am not chasing a power figure but I do want as much torque as possible from the standard turbo.
What torque/power would you expect this setup to give me? and could I change anything above to eek out a little more performance without breaking the bank? (larger injectors for example?)
Your thoughts would be appreciated

i'd be inclined to add a fuel pressure regulator and a dump valve to your setup along with a newer map sensor (fitted with the ECU).
The older map sensors are limited to 1.2bar max - the newer one will read up to 1.7bar so means you can run a little more boost mid-range to get the most out of it.

Thanks mate, pretty happy with those numbers

the only map sensor that "fits" is the original one, however newage ones and 97/98 ones and even after market ones all follow the same setup - 3 wires and 1 vac hose so fitting isn't a big deal.
if your buying a 2nd hand sensor, ask the seller if they can include the loom/harness fitting and a few inches of wiring to attach to your car.
For the fuel reg, any of the big brand names will do fine - ebay ones tend to be fakes/bad copies and will leak or randomly pack in leaving you without fuel at a time that you really need fuel so best avoided.

I'll avoid ebay fakes, I don't fancy fuel squirting about in my engine bay!
