My plans are to go t28 with 370's at 4bar. I know I need a new fuel pump. So just a question about the warlboro 255 whats the difference with lo pressure and high pressure. Which one would I need. Also where's the cheapest place to get the pump? And are there any other alternatives to the warlboro that drop in?

Get the low pressure pump. The stock fuel pressure regulator cannot handle the high pressure Walbro 255, and the car runs pig rich at high rpm. Or, get a nismo FPR, too.

if your going 4-bar you NEED the nismo fpr, so just go with the 255 pump and you'll be all set...also get yourself a fuel pressure guage to adjust your fuel pressure to 4-bar

I noticed a bigger jump in fuel pressure going to the 300ZX fuel filter than i ever did going to the HP Pump. Ive done alot of work with these pump as i sell them and make custom applications here and there for cars that Walbro doesnt have kits for. The 190lph is probably capable of everything youll need with the 370 setup but id say get the big dog...cause HP is addictive and youll add a bigger turbo or run more boost:).

I'd get the HP pump considering he's running 4bar pressure. That's what I'm using at least. No probs even after driving over 1k miles in one day. The pump does get loud after driving for a long time though.

I don't know if Im just not seeing it but is there a 255 low pressure pump? Or is the 190 pump the low pressure pump?
