My setup is running the 42lbers that came stock with the vortech unit. Computer duties are picked up by an autologic chip, and it utilizes the stock MAF with stock IAT location (ugh)...

Now I'm just running the stock setup, and I'm going to give EFF total credit for what I'm about to say (but I agree with him)...

These companies spend a lot of money making a stock kit that works. So long as you don't push it out of it's limits (reading the instructions will help), you should be perfectly fine and safe. People have been running JSRCs and Vortechs now for quite some miles on the included kit without any problems.

So if you buy a proven kit like JRSC and vortech, you slap it on, and you're good to go. You pay upfront for the kit, spend a bit of time installing, and save tonnes trying to make it work (like you'd be doing with a custom turbo).

One thing that is universally recommended is to get the car to a dyno after doing your FI install. $90-$100 will give you piece of mind that things are working properly, or provide hard data to return to the manufacturer to troubleshoot.

my own personal thoughts:

We all know that the JRSC makes a reliable 150 or so HP on a zetec, and close to 200 on an SVT. If you're not going to force it beyond those duties by installing smaller SC pulleys you're going to be just fine, and very happy at the end of the day. But do realize that the JRSC puts a ceiling on your FI mods. You can still gain with simple bolt ons to help the car breath/exhale better, which will lower boost, but so what, they'll respond very well to the mods.

and not confirmed with any empirical evidence yet...

Another reason I think the JRSC is a safe solution is that it pushes a fixed amount of airflow. Adding other mods should only increase the efficiency of the engine, and not force it beyond what the supplied kit can handle in the way of fuel..because only so much air is going to go through a JRSC.

Unlike the Vortech, which builds boost to about 3-4k RPM, and then bleeds off excess... a better breathing engine, is going to allow a lot more air through beyond where the boost was originally capped off, and that could put strain on injector sizings because you would flow more air at higher RPMs... so vortech users may want to be careful of the mods they put on...


I'm not sure how much of that makes sense, but that's me weighing in on the JRSC and the injector question....
