GT42R setup

[DSM "BISH"]

hi i am wanting to put a gt42r turbo on my 93 talon FWD. i would like to know what i would need to run this setup saftely at about 25psi to 30psi. i alreadr have a full msd igniton, wires and coils and ngk plugs. i have a rebuilt motor with about 4000 miles on it. and it has a forged crank arp rod bolts with the strong iron rods, forged pistons, the motor is bored out, it has a HKS 4 layer metal head gasket, arp head studs, and a stock but all brand new head and all hardware in it. a catch can, manuel boost contorller, solid motor mounts, 550cc injectors, and high flow fuel filter. what else would i need to run my Gt42R setup i want safetly?

thank you to anyone who helps me out!

Those injectors got to go otherwise all that air is useless. What are your hp goals?

 

[Dsmj89]

550cc ? Umm yeah you are going to need way bigger injectors to start off, dual fuel pumps, afpr, tuning device such as dsmlink or other of your like, and cams to make the best of that turbo.

 

[Last_resort_DSM]

Definitely 1000cc injectors or bigger, 272/272 cams or 280s if you plan on strictly making her a track car.

At 25-30psi you can get away with a 20g, 50 trim, GT35, holset, or a whole host of other turbos that will spool faster and cost less and not require a whole manifold setup.

You will want a tuning device. AFC, eprom, link/DSMap, you need to decide that yourself.

550's won't cut it. Come to think of it, 550's won't even max out your current turbo. Why don't you do that first, and use parts that will be helpful when the 42r comes around. Parts such as an intake manifold, cams, big 'ol injectors (1k if you want to run race gas, 1.6k if you want to run E85 which you should), a race core FMIC, and one of, or a combination of the above tuning devices.

A big 16g is more than most people can handle with FWD, and with even a decent tune it won't ruin your engine, so learn on it and have fun with it. There will always be 42r's (or HX4/50, or BW S3XX) for sale, so there is really no rush to go out and get the biggest turbo you can think of.

If you haven't learned to drive on a smaller turbo making power, when the 42r spools (at any speed), you will probably wind up in a ditch leaving a cloud of smoke behind you. That's assuming you were able to make a tune for it that doesn't destroy your engine. These are all things you can learn with your B16g, without fear of bodily or engine harm.

Personally I think if you're no focusing on pushing the turbo I think you're best off going to a smaller turbo. With the GT42R you're not going to be happy with it pushing low boost with a ton of lag that cannot compensate for the power that it'll make. Big turbo need high boost.

But anyways, get rid of those fuel injectors, you need to go at least 1000cc or more and dual pumps and ECM Link or EMS. You also need to do head work and go to 280 cam gears. And on the side note, you'll need to worry about the CFM on the intercooler too and maybe a SMIM.

Do you realize that a 42r is like a 1000hp turbo?

 

[1gDSM4g63]

Do you realize that a 42r is like a 1000hp turbo?

Yup, it's capable of that.

Realistically having a GT42R belongs in a non daily driving car. It really is a track car that runs race gas or full E85 and not matter if the engine is built or not you'll have a difficult times with that much power and the engine. And you do realized that it'll be a nightmare in a FWD car.

 

[frankenstein406]

no offense it doesnt sound like your ready at all for that kind of setup. I'd go with a big 16g or evo3 16g then max it out. I'm stoked for my evo3 16g setup. remember the biggest baddest turbo doesn't make you badass its what you can do with your car. my friend has a evo3 16g that he has on a fwd 2g and his biggest problem is traction, he even put on wider street tires. remember its not as easy as slapping on a turbo that can devour souls and running 7s, it takes time, money, and paintence. do you have all three?

 

[1gDSM4g63]

I already with frankenstein406, you don't seem to know so much and you'll most likely be screwing over the whole engine running a big turbo like that. By no means is running a T4 twin scroll turbo a slap-on turbo to make big power.

 

[DSM "BISH"]

i realize it is a high horepower turbo. i drag race mine every weeeknd now and it just had the base 16g on it and i grew tired of it kinda so im upgrading to the big 16g and i have had it for awhile now and i love it. its a good tubo but eventually ill want more and thats why i have the 550's is for the big 16g but these wont be enough even to max out that turbo?

 

[DSM_PWR]

Obviously a 42r is no where in the same range as a 16g...

It seems you havent done enough research on 74mm turbo's and honestly aren't ready... At 25-30psi, that turbo wont really come to life and you'll just be slowing your spool for no reason..

Unless your going for 700-1000hp, get something smaller that's better suited for your goals

If you want to know what supporting mods you'll need, go look at the first page or two of these and look at their mods.
DSM Dyno Challenge - Big Turbo
DSM 1/4 Mile Times - 1/4 ET

A 42r is a huge jump up from a 16g. Not only will you need air/fuel supporting mods, you'll need an FMIC, new head internals, a wideband, some tuning device, drivetrain upgrades, possibly slicks, etc.

With that kind of power you could possibly put down with the turbo, you'll also want (and most likely need) safety items such as a helmet, cage, possibly a parachute, some clothing, etc.

It would be an expensive project, but if that's what you want, go for it. Just do a lot of reading about what the high hp guys are doing and using.



Oh, and get rid of the iridium spark plugs...

 

[DSM "BISH"]

no i know the power ptential of the turbo and what it can do and what 40 psi feels like. my freind has a lexus with a 2j swap and it makes 860. i know what kind of turbo it is and what it does i just wanted to know what to do on a dsm to get it healthy enough to handle that kind of power. i just have a 16g right now because i cant afford a gt42 but im talking bout future plans. howm uch boost can the big 16 g push on my motor with the 550cc injectors?

 

[DSM_PWR]

To a 2JZ engine, a GT55r would be what a 42r is to us...

800hp can happen on a stock internal 2JZ (other than cams,headstuds,gasket)

.....howm uch boost can the big 16 g push on my motor with the 550cc injectors?

For someone who's been here a while... i wouldn think you've learned to search that by now ..

 

[daren_p]

If your future goals are to only run 25psi, then this isn't the right turbo for you. If this is the case, a much smaller turbo that is better suited to run 25psi would more then likely be faster. Sure the 42R will have a much better flowing turbine wheel & housing but if you haven't fully supported the rest of your setup, increasing its VE to support this, all you'll end up is with a laggy turbo that when eventually spools isn't happy with how low of boost you want to run. A smaller turbo such as a 50 trim or even an evoIII16g would probably be the faster car as it would have a much larger power band & is happy running those kinds of power levels.

If your friend has a 42R on his big power setup & this is why your looking at that turbo, remember he has 2 extra cylinders & alot more displacement. The way a 42R sized turbo responds on each of these motors is completely different.

If you plan to eventually run more then 25psi with this turbo & this boost level is just a stepping stone, then thats not so bad but in a fwd car the kind of power this turbo can produce, even at 50% of its rated output is useless unless your running slicks (& have the drivetrain to back it up). Normally if your ready to step up to a turbo of this frame size, you won't be asking questions like, what do I need to run this size of turbo? Also whats your budget? If you do want to build up this car to fully support that turbo & hold up to its power potential, you better have deep poskets. Ask any of the guys on here that are making big power how much they've spent on their cars, that actually race/push them. If you guessed 50K, some would probably laugh at you & say, I wish......

You want to jump from a 16g to a 42r. That is awesome, and you only want to run a 42r at 25-30psi. I have seen a few pump gas 42r setups making like 600+ whp, however who wants to wait till 6k to make power(Unless fullblown track car). You also need to rev your motor way past 9k, 10k would be the best.

You are not ready for a 42r. Dont waste you rmoney just so you can say I have a 42.

If I were you would would upgrade to an FP Green(~400hp) or an FP Red(~500hp) or a FP 3052(~500hp) and start there.

Good Luck, post pics of the build .

hey man its been said before, if you really have to ask about this stuff then your not ready for it. Have you ever driven a 800 whp car on the street? Jumping from a 16g to a 42r is like going from a ford fiesta (fun, fiesty and cant get in too much trouble with) to a ferrari 360 GT (fyi Ferrari 360 - Wikipedia, the free encyclopedia basically crazy all out stripped ferrari track only car). You are looking at $10,000+ easy just on supporting mods for this turbo. Trust me if you had that kinda cash lying around then you wouldnt be owning this car you would be modding the car posted above.

hi i am wanting to put a gt42r turbo on my 93 talon FWD.

I hope you plan on bumping the rev limiter up a bit....if not, look forward to about 1500rpms of useable power.

howm uch boost can the big 16 g push on my motor with the 550cc injectors?

Depending on your tune, anywhere between 1 and 39psi.

sweet. thanks for the replies
