HKS VPC installation -- guidance needed

Postby 3sgte4me » Tue Jan 12, 2010 2:05 am

Hi guys,

I bought a hks vpc -- for my st185 engine in my st165 currently running a jspec mr2 ecu.

The main question is about mounting the airflow sensor, and need to whether mounting it in the location of the cold start injector is best.

also, once the cold start injector is disconnected, do i need to disconnect anything else?

--- In addition what are the recommended injector size for a st185 engine with a walbro installed and running a ct20?

The cold start inj is a good spot for it.
you can also drill and tap the TB or the Intercooler outlet.
if you wanted to keep the cold start inj.
once the inj is unplugged there isnt anything else to disconnect.

You will need to have the vpc chipped in order to run the 550's.
you can run the stock 440's, but watch your gauges.
