2 Quick Question!!!!

[Happy]

I am maby in the process of buying a a fuel pump but want a know if it will work i nmy car properly!!
Its a trex 190 lph inline fuel pump! Its my roomates and it came with his ati supercharger kit and he just upgraded to a waldbo 340lph pump. So would this pump work and be any good on my car?? And what else would i need to run with it??


2nd question is i got a 16g(small) and am using my 14b hoiusing on it i bought cracked. And was wondering if i could port it out some to make up the difference from the 6cm2 to 7cm2?? possible or not?? Thanks!!

im not familair with that fuel pump, i would just buy a walbro 255 high pressure for $100 for the sake of your car and piece of mind.

as for the turine housing, yea, use it. just make sure you:

A: port the wastegate ALOT, both the hole and the surrounding, area, wallow it out GOOD or you will get boost creep.

B: get rid of the step and hog out as much as you can.

thats what i did and i run 20psi with no creep, and it spools quick.

but get a GOOD fuel pump, that extra 100 bucks might save ya 3000.

do i need a regulator or anything or can i just get the bigegr pump and run the rest stock??

a: real rule #7 http://www.dsmtuners.com/termsofuse.php#rules
b: what PSI does the pump put out? if you dont know the full specs of it, dont bother really. grab up a walbro 255 or 190 depending on your demands.
c: third, try to at least attempt to make your post easy to follow.
d: depending on the pressure it puts out, you may need a FPR at least (wont need it with a walbro 190 which runs around 43 psi, like stock). also look into a denso pump from a supra, RX7 TII, etc. they are quite and very nice.

you could also go by a 190lph from the 3Kgt VR4..they fit in real easy and are uiet..works well and seems to supply enough for your setup without major problems

While your in the rules section, check out #5 too, "5.USE DESCRIPTIVE THREAD TITLES. If it's not descriptive, it's not worth reading."

Spend the $95 dollars and get a walbro, a fuel pump made for our cars and not trying to retro fit another fuel pump you don't know will work or not. You might need an adjustable fuel pressure regulator.

I would be wary of using the RX7 or 3kgt pumps, or the supra pump, they work FANTASTIC, but unless you dont mind getting pretty creative with hooking them up, just go with the 255 high pressur, its direct drop in replacment, yes it whines a little.. but thats because it loves you.

check those out. the vfaq page will show you the diff btwn pumps.

if you look at the bottom of the RRE page, the RX-7 pump is what i have. nice and quiet, ahh. it was not hard to install at all. i was a pure noob when i put it in too!
