SR20VE with SR16 ecu set-up...

Now I've got the VE in and running on the P11, I'm looking at getting the best out of it. Currently I'm running her on just the low cams with a DE set-up (DE ecu, mat, dizzy, injectors). I'm planning to swap to a VE set-up with SR16 cams, SR16 ecu and VE maf & dizzy. However, it strikes me that the SR16 ecu and cams are set for a 1600cc engine and not a 2000cc engine. As the SR16VE and SR20VE both run 333cc injectors, logic says this set-up will mean I'll be running lean.
What are my options on getting around this? Would fitting larger injectors (370cc) help...?

run your de ecu with a afc, then get a rpm switch for the vvl.

im currently running a sr16ve ecu on my setup which has 370cc injectors and franklin S2 Cams (slightly more duration but approx same lift as sr16 cams) and theres been no detonation at all

SR20VE engine draws more air through the MAF, so if you have an SR16VE ECU/MAF it can run quite well as the ECU references a much higher part of the ECU mapping as it senses more 'load' and injects more fuel.

If I understand you correctly, I should be ok with 333cc injectors and I won't have any lean running problems...

You would be better to get 370cc injectors & a fuel regulator then you can control the mixtures a bit more & the 370cc injectors are cheap as. Several VE's here ran the SR16VE ECU on a 20VE with this setup... of course you can make it really hum with a bit of ECU tuning
