I have a 99 GSR and im starting a build.....i'm getting a log mani, T3/T04 60 trim .48A/R turbo (haven't decided on internal vs external gated yet) and the rest of the basics.......I'm thinkin of getting DSM 450s and i was told i didn't need a new fuel pump, but i don't know what type of management system is right for me. I was thinking of a VAFC, but i'm not sure.

My goal is 250whp......

Any suggestions on the management system welcomed...........thanks

 

I was told that i could street tune on Uberdata myself...but i don't know how. I have been thinking seriously about the VAFC because i know someone who will tune it for me....

 

Ditch the vafc....right away

Either convert your OBDII to OBDI and run crome/neptune/hondata or keep ur OBDII and get e-manage or AEM EMS.

The 60 trim, .48 a/r is small, and is probably doing to die in the upper rpm range.

Yes, you do need a fuel pump, get a walbro 255lph and you won't have to worry about upgrading it for a long time....

TIP: use the search! its got a lot of useful information thats been discussed many many many times.
