im building a turbo 5.3 for my 87 rx7, im going to be using 76mm turbo. i currently have -6 an lines with dual in tank walbro 255's.

What injectors do you guys suggest using for this set up? E85 compatible is a + as i am thinking about switching in the near future. Thanks

 

80 lb injectors will run out of fuel pretty close to the same time those 255s will.

 

what is your power goal?

 

Im gonna run on a conservitive 3-4 psi tune till i can get a built tranny/rear end. But my overall power goal is 600whp

 

you're well within the limits of the 80's and they'll have room for you in the future

 

80lb injectors will do 600 on gas or e85, not sure if twin 255s will do that on e85, probably.

80s are the ****, approx 325 dollars for the whole set.
hard to beat their flexibility and price

 

Sorry to thread jack but it is related. I am in a very similar boat, is there a specific 80 lbs. injector brand/company that you guys recommend?

 

Siemens Deka USCAR 80lb EV6 or EV1 (connector type)

my buddy at EFI source stocks them and you can also find them on Ebay and many other places

like that ^

 

Awesome.....thanks

 

no problem i also give away base tunes with those injectors installed, for megasquirt and stock pcm

 

Denmah, you give base tunes for E85? I've got a stock cam 5.3 with on3 76mm and those same 80 lb injectors from you're commonly bought items thread. A base tune to get the car running on e85 and maybe let me squeeze a few PSI out of it to check for issues would be great.

Ive fired it up on gas with the stock injectors to make sure everything was in running order. Was wanting to get a base tune from my local tuner so I could drive it there but he wants the full price of the tuning up front for it.

 

i only have an e85 tune for megasquirt 1 and 2, nothing for the stock computer,
honestly i am not a fan of e85, race gas is easier to get around here

 

E85 is at the gas station on the corner. I've used it in other builds. My last car had MS2 but honestly I would like to stick with the stock computer without a piggyback.

 

80lbs it is guys, thanks alot! denmah that would be awesome if i could get a base tune for those for the stock PCM. im looking to get these in about a month. i'll keep in contact.

 

I just changed from 60lb Dekas to 80s. 80Dekas is the way to go!

 

click on my wiki page in my signature and then click the hptuners base tunes page, everything is there

 

How much hp will they support?

 

Not sure but my 60lbs got me to 600+ with meth before they guit.

 

people say as high as 1000rwhp on gasoline, i have cars trapping 140 at like 50-60% DTC at 3500-3900lbs

 

denmah i look at all you YouTube videos you give great info! Trying to find you ebay link for wastegates
