What are the limits of my Walbro 190?

[dsmdeliveryboy]

So I'm running a Walbro 190 in my 1G right now, but I'm highly considering throwing the 18g from the old gsx in it and injectors with link but I'm wondering if I'll need to upgrade to my fuel pump to a 255. I only plan on running about 23-24 psi with the turbo, and I've seen people running upwards of 24psi with a 16g and a walbro 190 with no problems.

I've heard it thrown around a lot that ~400hp is where a re-wired 190 will start to run out of steam.

I have no factual data to back this up.

I ran a 190 with a evo 3 at 21psi, and e85. I kept the same solid afr all the way to redline, with no leaning out.

Will I NEED a FPR if I switch to a 255? Because I might trade someone my 190 for his 255.

highly recommended. it's not a necessity though, your stock fpr will try to hold 37.5lbs, but probably will not last long.

throw a 255, rewire it, throw on a aeromotive fpr and be done with it. if you want to go fast james, at least do the proper supporting mods, or you will be one of the guys that gives us a bad rep. .

i have a 255 out of a rx7. unknown condition, came with the car.

You don't NEED to run one but it will make things ALOT easier, as to why it's always recomended. Your base pressure will be greatly increased forcing you to re-tune just from installing a fuel pump.

Some people debate that a stock 2g fpr in good condition will be fine with a 255, but I don't think anyone trusts the 1g to not overrun.

I have personally run wally 255's on a 2g fpr and 3 1g fpr's with no over run at all. I guess it is like crank walk, it hardly ever happens but people make a big deal of it anyway.

I'm gonna be looking more into FPR's, I may just run the 190 till I can afford to buy a whole fuel kit(something I've been wanting to do but keep putting it off).
