Starting my turbo build

[Fondle]

im gathering the parts, so far i have the turbo and the plugs and wires but i was curious if it would be fine to use stock injectors from a ls1 car, or do i need bigger injectors than those, they are 24 lbs/hr

Re: Starting my turbo build

what year is your car and it depends on the boost you plan on runnign i am running 87% injectory duty on stock injectors with very few mods

Re: Starting my turbo build

my car is a 1999, i think the injectors are off of a 96, im probably only going to run at most 10psi

Re: Starting my turbo build

I believe I've heard people running up to 12 psi on a stock engine. Now that may or may not include stock injectors but you will be able to tell injector duty with HP tuners. You are getting HP tuners right?

Re: Starting my turbo build

Also depends on how big of turbo and cfm, I would think 36lb injectors at least with 12 PSI or might have to go 42lber's. Thats why I bought 65(60) lb injectors to cover me if the 36lb injectors I'm running max out. I think most have ran stock injectors and FMU up to 8 PSI.

Re: Starting my turbo build

i wanted a small turbo so i could spool quick since i was going to run much boost anyways since i have 126,000 miles on my car, so i picked up a t25 out of a 300zx

Re: Starting my turbo build

Whats the specs of the T25 , so it doesn't choke up top in the RPMS?

Re: Starting my turbo build

what specs did you want?

Im currently running 15 psi on 42 lb injectors. I ran 12 on 36's and they were maxxed.

You wont be able to boost too much with the stock injectors unless you use an FMU. 24's may be enough for a little baby turbo with low boost, but thats about it.

what specs did you want?

Size of the compressor, size of the turbine, trim, etc...

A T25 sounds puny. I think you'll upgrade to a 60-1 or 62-1 very quickly.

Re: Starting my turbo build

damn i just had all the specs up and now i lost the page, i think its a 56mm, i need to find the page again

also, i thought i had to have a fmu to run turbo, how do i run it without one?

how many miles are on your camaro?

Re: Starting my turbo build

Get the right size injectors and tune the PCM with HP Tuners. I highly advise against an FMU, thats just a bandaid for fueling. Do it right with injectors and a tune.

how many miles are on your camaro?

Almost 90,000

Re: Starting my turbo build

well im at 126k so i dont want to over boost, do you think a t25 is too small to run 8-10 lbs?

Im currently running 15 psi on 42 lb injectors. I ran 12 on 36's and they were maxxed.

Sweet, I'm planing on 12psi eventually and I've already got the 42 lb injectors in. I'm still learning, so I should probably stop spreading rumors. :D

There is a dude on FTV6 that has 125k on his stock motor and runs 20+ psi of boost and 11's in the quarter mile. Its all about a good set up with good tuning.

do you think a t25 is too small to run 8-10 lbs?

If its a stock turbo off of a 300ZX, Im willing to bet its WAY too small. It was designed for a 3.0 liter motor AND for a twin turbo system, not a single.

I would ditch it and get a proper size such as a 62-1, 60-1, or a t3/t4 hybrid.

Re: Starting my turbo build
