some fuel system questions...

[Guest ON3GO]

ok i did a few searchs and some helped some didnt.

anyways.

as prob everybody knows ive been spending alot of money on my Z, and nothing is really done, and i have like 2 months to finishg it, like in running order.

lol.

anyways sense im going to do a L28ET swap in my 76' 280Z ( I WILL DO IT BEFORE I LEAVE!!!!!!!!!!) i totally forgot about the fuel system.

like aboit the gas tank, fuel lines and such.

so here it goes.

i wanna do stainless steel fittings.. 1st off is this a good idea?

also what size lines will i need and about how many feet will i need.

what fittings should i look into and what degree bends if it makes a difference.. as you can see im lost and have no clue about this stuff.

sense i have a 280Z, do i still need to rig up my stock gas tank?

if so what do i need to do.. remember cheapest and easiest way to do it.

also this might not be for this secton but do i need a oil-cooler?

i know Earls is good but alot of money but ive been finding them cheap.

good idea? any type of oil cooler would i need?

im sure im forgetimng alot of other things that i need to change and such for this swap so if you know please tell me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

thanks

anybody?

need to figure out how much i need to spend..... im a a very very very very tight budget.

have you finished your suspension yet?

heres the good part about efi on a 280z

its already there!

just put the fuel hoses to the same place as you already have them

no mods to tank, it has baffles

right now im using a tranny cooler as an oil cooler, doesnt work too good.

Im going up to an RVsized oil cooler

For some reason only auto zxt had oil cooler i believe

Colder oil mean better lubrication, better lube means (sp) mo(more) BOOST.

suspension is done, im putting it all together now i just still cant find anybody to section my struts ..

still looking to get stainless steel brake lines too.

i was think of getting my friends FC RX-7 oil cooler but its big, and im gonna be lacking space because of my FMIC and such.

so i dont need to do anything to my gas tank when putting in the 280ZX turbo motor! AWESOME!!!!!

im looking for stainless steel fuel lines now too.......

 

thanks

The manual trans zxt didnt have oilcoolers. If this is true how much boost can you run. Mike i'm stuck the same place as you. And

I also do not know much about fuel management. I'm thinking about going with an sds once the l28et is in, is that a good idea.

Things i know you need for the swapAFM

ECU

injector leads

distributor

knock sensor-can be left out, ive found that when they get old they get

problematic

head temp sensor

o2-car will run without one, but mpg will be crappy and if other

sensors arent workign right with this, youwill foul plug after plug

tps

the fusible links to ignition and efi

good grounds to harness

efi relays one is green and one is tan,

Would be even more lost if it werent for len, he knows alot about the swap.

Any more info on the efi would be helpful.

Thanks to all,

John

I dont like the idea of jumping into a standalone if you havent done one before, Its just me. Its not very hard, and the only issues ive had thus far are from loose connectors, and a crappy 02. Once youve mastered how it works, general principles apply and you will have a much easier time learning how to tune a standalone for max power. I wouldnt go to a standalone if the alternatives were so limited, and the fact that the jwt ends up costing almost as much as a haltec setup, or the difference between the two is insignificant if you plan on doing a lot of upgrades.

I dont think the oil cooler is a good idea, but since most people dont spend five minutes in full boost, usually a few seconds, not a life or death thing, but it is a good thing to consider.
