you need a chipped ecu, safc might do it as stock maps are pretty conservative...is that a hks gt3037r or a garret gt30r?

[Komatsu X]

its the HKS GT3037 Pro S... how would i go about geting my ecu chipped? I just picked up a APEX'i S-AFC II today.. So do u think i should just stick with that are get my ecu chipped?

[Kansei240sx]

Get it chipped. The safcII cannot run 550 cc injectors on the RB20 as that is larger than 50 percent the original size of injectors. So you have to have a chipped ECU for it to work.... The afc is a nice tool but should only be used for small adjustments.

As far as getting the ECU chipped i myself am looking for that alternative.

[Carl H]

kansei, you *can* run a rb25 off of a rb20 ecu but you will need to remap it and add a rpm window switch for the vtc to work correctly...

so gow big an injector can the S-AFC II handle on the rb20? 405cc? one of the new sponsors...Deatsch werks sells direct fit high flow replacements.have you checked out their link?

you sure about this? safc's have taken DSMs into the 9's.

[DriftingisLame]

DSM's already have huge injectors stock (440-450cc's?). So when you plop in 550's or something you wont have to correct as much as 550's replacing 270's, like on the rb20.

I have 440cc inJectors .. Do you think i can reach 380hp with the 440cc injectors and the S Afc?? are should i just get my ecu chip? i really dont want to spend exter money if i can do it with something i have here at my house..

[mugengsr]

i dont think you will be able to trim the fuel down enough with an safc to make it run right with the 550's in it .. 440cc gtr injectors are still a chore .. ecu tune would be best .. then use safc for fine tuning ..that setup is more than capable of 370hp with correct tuning

Sweet anther RB20 local to me. Lets RACE!!! j/k my car is not running yet lol. Hit me up man, I'll show you a good place to get dynoed at.

[Carl H]

you will need 550's to keep the duty cycles sane, i know this is a highly debated topic but i run larger than neccisary to keep duty cycles down...380whp is roughly 440bhp, so those injectors would be screaming...

[Komatsu X]

sweet im down to ride but in my street car i think it has around 300hp right now .. i got alot of friend at uti so i can get my car dyno for free . well if your down to drift hit me up anytime if i have gas im down lol....

[Yellow4g63]

No Drifto action for me. Let me know when you get your car done.

[Komatsu X]

well just roll ill be doing alot of drifting tho

[mugengsr]

thats is true carl .. the 440's would be working their *** off .. i was not aware he wanted about 370 whp .. either way 550's are a must and ecu tune is also advisable..
