turbo_sir

i have a stock jdm gsr in my hatch i have recently bought a t3t4 turbo setup, i would like to run 10lbs. it is my dd so i would like it faster but im not building a race car just got the turbo for cheap haha. i would jus like some advice or opions on what is safe to do in order for it to run good and eliminate any problems it could cause.. recommended injectors, maybe block gaurd? head studs or gasket. really anything to be safe i want to do this right the first time which sucks cuz i have to stare at it in my room every night lol

eg6sir

you can boost 10lbs safely on stock internals

turbo_sir

i heard i would need some arp head studs to run more than 8lbs is this true?

pissedoffsol

ignore psi... you're good till about 275-300 WHP on a professional tune with proper fuel management.

turbo_sir

What is prefered for fuel management? I was thinking of running some 450 dsm injectors my friend is giving me and buying a walbro 255fuel pump, is that good or will I need to get like a aem or hondata unit?

eg6sir

chipped ecu and chrome pro

turbo_sir

K well I have the ecu that came with the motor and it is chipped with a spoon chip is what I was told redline 9k and vtec 5200 would this be okay or do I have to have a chip made for my tune?

eg6sir

you would need a good tune for your setup.. Spoon chip wont be good for turbo apps

pissedoffsol

the spoon chip isn't good for N/A, either.

I HIGHLY suggest you take your car to a dyno and have it pro tuned. the 500 buks you spend will be much cheaper than blowing up.

turbo_sir

so pretty much put some injectors in and get it dyno tuned for 10 pounds and i should be kosher?

gettocrx

Yup! I say 10psi with stock internals will be fine as long you get a good tune and at least rc 440 or 550 injectors!

turbo_sir

K thank you everyone for your help and for the injectors are some stock ones fine out of a dsm? 94 awd talon I’ve heard arguments on both sides for these but they are so easy to find and it’s the size everyone suggests to use

pissedoffsol

they are a pain to set up, but are cheap. you need to bore your rail out a little and wire in a resistor pak.

or, you can spend more money and get some RC440's

eg6sir

i'd spend the extra flow and get the RCs

turbo_sir

k i can get some 1000cc injectors for 340. and buy hondata get it installed and tuned for 600, is that a good deal?

GSRCIVICTN

1000cc injectors for your power goal is too big. I believe you would be better off with some 550's or so.

turbo_sir

see i was gonna roll with some that sixe but the guy installing my hondata recommended 1000s so i dont ever have to buy any more and the hondata will tune the injectors to run how i want them so i wont be dumping extra gas

pissedoffsol

550s are plenty big.
1000's are a PAIN to idle, and you'll spend more time and money trying to tune them for your modest goal.

in all honesty, i'd find someone else to do your hondata... cuz this guy doesn't seem to have a clue

turbo_sir

this guy really does know what he is doing(9 second civic) he just was sayin put big ones in so i wontever have to get ones later and he can change the impedancelevel or something with the hondatafor the injectors to run however we need them. is thata good price for the hondata and tune and everything though?

turbo_sir

no disrespect to anyone i value everyones opinion i just know first hand that he is good at it.

christ.deyoung

but how reliable would that be for a dd?
what engine parts would it be a good idea to upgrade? rods,pistons,valves,cam,springs?

The gsr motor has fairly decent compression from the factory. Running 10 psi is possible but probably isnt the best idea for long term durability. I tunned a stock gsr that had a drag turbo kit with 7 psi and it made about 230 at the wheels on a mustang dyno. The car was very quick just with that amount of boost. You could run a bit more boost if you like, but dont skimp on the fuel management. We were running 440cc rc injectors on that setup and they were more then adequate. I would run nothing more then 550cc injectors for your horsepower goals. They will still maintain good idle characteristics and you shouldnt see more then 80% duty cycle at the absolute most. Defintely convert to obd1 if you are not already and run CROME or hondata. I prefer CROME over anything because it works great and is very reasonably priced. DO NOT buy some unknown chipped ecu for this setup, you will probably blow it up in a matter of minutes. You need professional tunning to make this setup work and be reliable. You are better off buying some new injectors from rc just so you know they are good. I dont like used injectors unless they are tested and cleaned professionaly. But new ones are reasonably priced and are worth the piece of mine, also that way you dont have to fuck with a injector resistor box. They will be plug and play, unless you need the obd1 injector clips. Good luck!!

I'm after a turbo for a gsr B18C which will produce up to around 325hp, however I dont want it to be in boost (or under very little boost) until around 3500+ rpm. Any suggestions on what size/type of turbo to go with?
I was thinking about a Garrett T3/T04E....would this be appropriate for my goal?

turbo_sir

k im going to get some 550 rc injectors and i think im going to run with the hondata cuz i have heard so many good thing about it and how easy it is to tune. i eventually will start to build the motor prolly this winter but until then im anxious to put it on but still would like to do it the right way......chris.deyoung the bigger the turbo most likely the higher rpms it will spool depending one turbo housin. i got a large turbo so i can boost when i really want to as well as get better gas mileage instead of a smaller one that will be boosting alot sooner

boostin4fun

I am using the same turbo for my boosted ls/vtec. However it is a turbonetics that is a 50 trim, .48 ar. It would be great for what you want it for.
