Ok guys need some more help on this build. I'm looking for bigger injectors. Would the turbo injectors be a better size. I'm trying to get the most power out of my l28 I can with out adding nos or a turbo.

FricFrac

You can't just add bigger injectors...

I'm getting the stuff little by little. What I can afford at the time. I'm not going to put them In until u have everything else.

You need a game plan. What do you want to accomplish and what is your budget are the first two questions to be answered - injector sizing is one of the last things you'll need to worry about....

Ok I just told you I want to get as much power out of my engine as I can. And I'm trying to get the parts I can when I can I know I'll need bigger injectors latter down the road so that's why I'm asking about them because I don't know she I can find anything bout them in the web.

what do you have as now for power ?
and fricfrac is right you need a game plan..
so what is it going.. straight, sideways, or just to have the power ?

Mike, seems like the 280 Z guys here have done the most mods of anybody on this site. Everything you can think of doing to a 280 has been done by somebody here. When you get to a specific point, just give them enough info and ask them. You will get experienced responses from guys who know their beans. Just check out the archived 280 forums to see what I mean.

game plan is def what you need. first things first, no point in stock piling stuff that won't go in the engine for a year or 2. spend the money on sale items early but buy things you need now.

1. get the engine running correctly and reliably before moding it.
2. do good upgrades like a light flywheel and good clutch and ignition. know your ignition system your going to use and work towards that so you don't need to upgrade twice.
3. air intake. super simple but plan it well, cone filter new manifold and tb
4. stand alone ecu. get it running on basically stock motor.
5. header and exhaust. 3-5 can be done in any order really
6. fuel pump and injectors, again make the stand alone work again, its gonna need to be played with every upgrade
7. internals. more compression, flow bench, balancing etc. cam
8. final dyno tune.

Ok i have a plan I know what I need I'm just simply asking about what kind of injectors I need. But every one keeps telling you can put injectors in yet. I know this Im not going to put them in yet. I have a buddy selling some turbo 280zx injectors. I have a chance to get the bigger injectors now but I don't know if they will work for what I need that's why I'm ask you guys. But Boone has yet to tell me if they will work.

Iv already bored it .03 over with flat top pistons. My compression is around 210 on all cylinders. I'm getting a new coil pack and rotor botton and dis cap just pit in new pugs and I'm getting new wires. I going to get a header fIt and Im gong to make my own intake if I can't find a better one somewhere esle. I'm making a new fuel Rail. I'm going tO get bigger injectors. And a stand alone ecu. I'm getting a 60 mm throttle body. And I'm gOing to fab a ram air for it.

You need to do a tunable ECU like megasquirt now, and as you add new parts you can tune your system to them. You need to be able to make adjustments to the computer so that you are taking maximum advantage of your upgrades.

Well see again will the turbo injectors work for what I néed. I know I need a new ecu don't know yet what kind but I know I need one.

PredatorZ

I guess its just not sinking in, anything will work if you get a programmable ECU, but they may be a waste of money, because you might want to go larger.

bigmike409888

See that's what I'm asking if those injectors will be big enough?
