Current Setup:
Car: 97 Lancer, FWD
Engine: Stock JDM VR-4,14B turbo,450cc,vr4 intercooler,stock fuel pump, stock BOV.
ECU: MD165808 (This ECU came from the 240HP Galant VR-4 RS,with 510 inj and 16G Turbo)
Mods: 3” exhaust, K&N filter, MBC, Exedy Tri puck Racing Clutch, VR4 AWD Tranny locked for FWD setup.

Boosting at 16psi using 97+ Octane Pump Gas.

I'm planning to do some upgrades soon with just bolt-ons. I dont have plans on buying an AFC yet (If possible?), which combo will be best without using an AFC.

My goal is to run higher boosts without fuel cut. Run High 12’s, low 13s at the strip.

Here are my plans..

Option 1:
550cc injectors, 2G MAF from EVO1-3, Walbro Fuel Pump 255lph

Option 2:
Same as option 1 plus Evo 3 Big 16G turbo.

Please add additional mods that I need in option 1 and in option 2…like FPR etc.

Thanks in advance..

If I were you, I'd go with option 2, and a B&M afpr.

as far as running low 13's.... maybe on race gas and a lot of boost..

You will need fuel management if you go with larger injectors. If you go with the 16g, you should go with 650s instead of 550s. You will need an afpr for the 255 pump, however, anything but the B&M ComandFlo.

Thanks for the inputs.

Will the stock FPR give me a rough idle on a 255 pump?

Thanks alot. Got it.

You're welcome.
