I got a turbo II with a bigger turbo. Planning to run 10-15 or more psi with a haltech E8 ecu. I was thinking of 4 - 1000 cc injectors. Or should I just get bigger secondarys or what? I really don't have a clue.

It's the last thing I need to start up my FC, Any Ideas please? thanks

 

"Bigger turbo" is not particularly descriptive...

4x 1000CC is probably fine for most "bigger turbos". You'll also need an upgraded pump.

 

I got a walbro pump on the way, so 1000cc's should be fine? I will order them right away

 

Oh im runnin haltech E8, should I get low impedence or high impedence injectors? Whats the difference anyway?

 

I just got the 4- 1000cc injectors from venom on ebay. e6k runs them just fine when I had an fd pump in last.

 

Again, what does "bigger turbo" mean?

 

Those are the exact ones I was thinking about getting. from ebay seller tlfsupra89?

 

Depending on the turbo, 4 x 1000CC might be massive overkill, or massive underkill.

It's impossible to recommend a fuel system without knowing the turbo you are going to be using.

I find it amazing that no one else has asked this question.

 

just go with 720 pri, 1600 sec.. it doesnt hurt to have the capability, since they all pretty much cost the same anyway. 1000cc may be to big in the pri for idle

 

What kind of turbo? What kind of HP level?

 

Well I wasn't gonna post my setup until it was done, but here it is. Please don't hate

It's a Garrett turbo with a T6 inlet flange. The specs that I can remember is its got a 1.34 a/r hotside. I got a really good deal on it and didn't know it was a T6 until after I paid for it. I know this turbo is hella too big but I don't care. On the next rebuild ill bridgeport it and throw a ballbearing on there.

Heres some pics, remember don't hate please

 

I wouldn't go with Venom injectors,

Unless you have a bridgeport, that thing won't spool.

Post the inducer and exducer sizes.

The hotside is huge, the compressor looks small...3" inlet?

What numbers are on the compressor housing?

You'll need more then 4 x 1000CC. Best go 1000CC primary and 1600CC secondary if the turbo is a big as it seems from the outside.

 

thanks for info bizmarkie, ill look into RC's instead.

I lost all the complete specs on the turbo. But the exhaust housing looks way different than anything ive seen to my knowledge on turbos (not that much). I believe it was slapped together with random parts. No one makes a 6 bolt outlet flange that big, I have to get one custom made

crap, i got to go to work

so 1000 pri. and 1600 sec. should be fine?

 

800 primary 1600 seccondary. or 550 primary and 1600 seccondary.

it i would go 720pri 1600sec.

i run 550cc 1600cc sec on my bnr stage 1 turbo with my e6x. i have no problems what so ever. the turbo isnt big enough to work out those 1600cc's though.

whatever.

you need to get more specs on the turbo first, then find out what kind of power youll want to be making. there is an online calculator that will tell you what hp each kind of injector will reach at a certain duty cycle.

 

Its probably alot different considering they have to run 6 at the same flow rate per cylinder. We only have two that fire together so it doesn't seem like it would be that big of a deal.

 

It looks like there's a lot of really big quality issues with them in the thread. I think that it'd be better to pick something else...

 

Thanks for the info everyone, yall really helped me out alot. Ill keep trying to find the specs for tha turbo

 

1000cc primary and 1600cc secondaries...

Just as Aaron Cake said...

 

And that's most important. Without knowing at least the size of the compressor it's impossible to know the capabilities of that turbo.

Honestly though, it's a poor choice to just buy a random turbo because it's available. Decide what you want to do with the engine, and then pick a turbo to match or spec it out yourself.

 

What about low and high impedence? Wich ones do I need and what is the difference?

 

That looks like a gt42, is this going to be a pump gas engine or are you planing on ever running race fuel? With race fuel you will need something like 2 82lb primary, 2 160lb secondary and 2 160lb in the tb elbow. Your walbro will not support that turbo on race fuel.

 

I just ordered these for my BNR stage 4 setup

and these

as for high and low impedance, you can do either but with low impedance you need resistors for low impedance.

 

You can get the 1680cc Bosch injectors cheaper from KG Parts and they come with injector clips.

I run 720/1680 @ 40psi base pressure and I see about 80% duty cycle at 21psi boost on a 60-1 T04S turbo, so basically a BNR stage 4 wheel with a much bigger compressor and turbine housing.
