SR20DET/ what fuel pump to use?

[s13 ziggy]

i plan on doing an sr20det swap soon and i just wanted to get some things straight

do i use a z32/300zx fuel pump?

and do i use a z32 MAF>?

You need to do MUCH more research before you try this. Those are basic questions. Make Nico your new home and do a lot of reading. I don't know anything about a 300zx pump, but most people go with a Walbro 255lph. No you don't use a z32 MAF, unless you're going for high horsepower and getting a tuned ECU.

well thats why i am on here man.

then what MAF do i use?

[zachattack_5491]

You're missing the reading part though. I'm not hating, I'm just saying it would help to read first, then ask questions. I would imagine you would use the MAF from the SR20.

i understand that but everytime i try to search stuff on here it comes up with random s***. and i would have thought so too but i heard it is better to use the z32 MAF

Oh yeah, I've never learned how to use the new search on here. Last I checked it kinda sucked. This works for me, do a google search but do it like this: "Search term" site:"Nico URL" or to search subforums just put the subforum URL like this--> z32 maf site:"sr20det-forum-rear-drive.html" Sorry if that turns out like a link.

Z32 maf is used when you need to measure more air flow for higher horsepower. The stock maf peaks at like 260 or something, don't quote me on that but you get the idea. To use z32 maf you need to send your ecu in to get tuned, or run an aftermarket ecu like emanage, power FC, etc.

oh ok well that makes since. my friend used a z32 MAF and he fired his up the other day and the first time it started right up then smoke came out then he FRIED his ECU. he was f*** pissed

Supra pump hardwired

[s13 ziggy]

can you please explain?

[Asia989]

it requires 10gauge wire in line fuse and relay. it gives the pump a direct 13-14v insted of 10v
