it's a little more than halfway down the page. it shows thier older one and newer one both being able to handle more than the walbro but I've never seen anyone else with the same pump. Maybe cause it's expensive?

 

We use a special, high flow fuel pump, made by OE manufacturer Denso in Japan
it’s still a direct bolt-in application and still a quality Denso pump.

Hmmm...still a Denso pump. Supra is a Denso pump. Maybe an HKS modified pump?
Supra Turbo MKIV (Denso 195130-1020)
HKS 1407-001US (a modified Denso 195130-0771)

 

Wow, no kidding.

 

No you idiot, I was going to convert it to turbo but It needs the S5 engine.

 

those rx7.com fuel pumps are denso pumps as well.

 

Well, your post did make it sounds like you wanted a 400 hp NA.

 

Bad move

 

yep...my setup, using Supra TT pump, yielded 470 whp on Race Gas.

Just a simple drop in.
