I wouldn't install any of it, if I weren't planning on tuning it. You always stand a good chance of doing irreparable damage.

look into FMU's aka Rising Rate Fuel Pressure Regulator (RRFPR)

I wouldnt run more than 4psi on a T3T4 without tuning.Craving4Boost makes a good point though. An FMU with a 8:1 ratio will be OK for up to 7psi if you run 93+ octane.

For the record both of your Post that you made with two differ names, could have been covered in one thread. Since they are both pretty much about the same thing.

We don't want to clutter up the board with the same questions in differ threads. If you make a mistake in the title in the future please let me know and I will be more then happy to fix it for you.

sorry but i didnt want to seem like i wasnt getting it cause i do but owell. any ways the reason that i asked is that i used to have an 01 firebird v6 and was planning to do a sc or turbo and you really didnt need tuning until you pushed 10lbs or more. plus tuning for the ecu on my firebird was like 300-400 from a company here in texas... thanks for the help

Just run like 100 octane and you can run 6psi alright.

I wouldn't trust me though. I sure don't..

I run 14psi on my car, but I run 110 octane, and like a 8.2:1 compression ratio.

If your trying to be cheap, just but some sr injectors for 100.00 and a SAFC for 200.00 so that you are much safer, not saying this is by no means the best way, but safer than what your thinking.

Best way to do an inexpensive low boost setup:

T3 60 or super 60 - bonus for stageIII exhaust.2 steps colder plugs93+ octanedizzy retarded 2*8:1 FMUWideband O2 sensorNo IC2.5" exhaust

Run no more than 5-7lbs

hey i just got my sr injectors and i also saw some setups using the n60 maf. i just happen to have a wrecked 96 i30 in my garage. iread somewhere that if i do the 370cc injectors with the n60 maf that the motor would be good for 6lb-8lbs. add some alcohol injection and bump it up to 9 or should i dare 10lbs with 93 octane and remind u it is intercooled also. well i think that im going to do this setup so il keep u posted with pics of the install and tell yall how it runs..my setup:t3/t4fmicsr injectorswalbrogreddy bovtial wastegate 38 mmn60 maf

how are you gonna account for the bigger injectors and bigger maf? That will be your tuning right there!!!!

so u think my setup wont work ( sorry for the stubborness of not tuning just want to do this without spending to much money)

i am under the impression of his from ka-t .org

"I had heard that running an N60 maf would require about %30 + more fuel than a stock maf, also the stock 370s run about 30 less"

I ran pretty much that exact same setup on my SOHC KA for almost 20k miles until i siezed an injector

The SOHC injectors are 260cc (DOHC 270cc) and on a T3/T4 50 trim .48 ar turbo @ approx half a bar of boost (around 6.8 lbs) you are pushing those injectors to over 90% duty cycle.

You may want to invest in some used purpletop SR injectors for the time being. they'are about 27% bigger and although you will run a tad rich @ idle, it's better safe than sorry.

I only ran un-tuned because I wanted to test what the motor had in it and I planned on doing a full rebuild w/ one of my other 2 spare motors.

your ECU will be capable of getting you to stoich at idle and mid-throttle but you will need something to tune for WOT and you may want an aftermarket FPR as well.

you can pick up an SAFC II for under $200, if you are planning on running this motor long term I would suggest spending the money.

Man, have you searched this forum at all?

You can't change injector size and MAF without tuning for them. You will need an SAFC at least.

Plus, you are being silly. Why would you want a big, slower spooling turbo and a MAF swap to run 5lbs; it just doesn't make sense.

If you don't plan on more than 250HP (where the 370s will max), you can use the 370s with a super 60, your stock MAF and an SAFC.

man ive have searched for the last week since i got my turbo kit. all i need is some form of tuning. some guy on ka-t.org had a t25 setup with sr injectors and and n60 maf. he was pushin 7lbs without a sweat with no tuning. i also want to know if the e60 maf on my 96 i30 is the same as an n60 maf. sorry for the stubborness but not everybody has enough money sometimes. i just want to run a safe amount of boost without tuning. imsure somebody has done it. i found the guy and his link is up in one of my replies. thanx for all of the input that ive gotten especially me being a newbie at this forum.

Not to be rude or mean or anything, but if you say you saw some guy do it like that then why keep on asking the same question over and over again.

You can't have reliable with cheap. And as for your maf question I did a quick search on Google and found out, that those two mafs are different.

IMO do like everyone said to do, get an inexpensive SAFC, I see them go for less then 200 now days, back off your timing 3*.

I mean all of us are trying to get through to you that you won't really be able to get this done with out tuning.

I also completely understand not everyone has money, thats why I would hold off with this project a lil more and save up until you feel comfortable with your fund. Cause believe me there will be a lot of small things that you will end up buying here and there, and those will add up.

You are going to pay alot more to build or replace your engine in a few weeks than what it would have cost to buy at least a SAFC, but either way you will learn the hard way, just going buy your comments.

I ran 8 months of FMU at 6psi with a couple degrees off of my timing. I'm still on my original engine.

Ok, here is the deal. You are only looking for a bit over 200HP correct? The stock MAF is good for around 270HP and is far easier to tune, so keep your stock MAF. Yo have 370cc injectors - you will need an SAFC to tune for these or you can't use them, got it? Plus, you do not need or want a big turbo. A T3 super 60 will be more than enough to deliver what you need and it will spool faster. So, here is the bottom line and you don't have to ask the same questio again.

Get a T3 60 trim or super 60 trim - T25 will also work.Use 370 injectors and your stock MAF - tune with an SAFCTiming should be fine for 5-7 lbs - to be safe run at least 1 step colder plug, use high octane fuel and maybe turn your dist back 2*.

Don't forget, you will also need a blow off valve and exhaust work.

If you don't have money for an SAFC, sell the 370s and buy a 8:1 FMU to use with the stock injectors and MAF.

Got it?
