Injectors or turbo?

[TTipswprd]

Based on what ive done to my truck so far, should my next upgrade be a new turbo or injectors? my egt's at highway sppeds are aroun 7-800 with about 1100 max. i dont tow alot but do take the boat up ocasionally to the lake, or a bed full of whatever. I also wonder if head studs afre needed for a new turbo. I do not know a whole bunch about injectors so can the all mighty smart ones please help!

You will find out that if you put big sticks in you will need a better turbo too.

A bigger turbo will be laggier, and won't be fun to drive. A bigger set of injectors will be fun, but you won't be able to use it to work.

Basically, more air without the fuel to spool it is no fun, more fuel without the air is fun, but not useable.

Most people choose to upgrade their injectors before turbo.

I still have stock injectors and a slightly tweaked pump, and just bought a 62/65/12. It's gated at about 30-35 psi and spools faster than the poor H1C ever did.

If your pump is maxed out, you may want to consider getting some injectors and turning it back down, just to make it's life a little easier.

IMHO however, I'd upgrade your turbo and back the pump down a bit anyways. My truck runs much better than I though it would, and though I have to keep an eye on the pyro due to the 12cm housing, It would only be worse if I just threw some hot injectors in it instead.

IMHO of course.

Get a bigger turbo for it that CAN support the injectors, and Then do every free modification to the injection pump and when you can afford injectors, pop them in and back the pump down.

That's the way i look at it, theres so much fuel you can get out of stock injectors with just messing with the pump, Fuel pin ground or aftermarket, power screw cranked and lots of timing and you'd be surprised

ok so for a turbo im looking for basically faster spool up without a whole lot more boost and heat because then i will need to upgrade my headstuds if i understand correctly.

A stock injector truck, with a turbo that will support high horsepower, will be laggy and not fun to drive. Even with a lot of pump tuning it would still be hard to lite, and wouldn't be very enjoyable to drive. (I'm talking about something along the lines of a 62/71/14.)

What are your goals horsepower wise for this truck? A Super 40 will get you 400rwhp that you can still use to tow and play, and with some pump tuning it should lite fairly easy. If you're after 500+rwhp, a 62/71/14 (twins more than likely) is the way to go.

If you still want to tow, go with a Super HX40, especially with stock injectors. I've been told it isn't much harder to lite than an HX35, but it will still cool very well.

You don't need to worry about the gasket letting go until around 32-40psi of boost.

i am not looking for a real high horsepower truck. id just like to putt around and wait for some billy bada$$ that expects to beat my old ugly truck and whoop em! only other mods i want are injectors, turbo, and exhaust with some cooler tubz and still be able to tow a medium load if i have to. i just hate the lag in my turbo. also i am going to college and dont have a job because of recent shoulder sergery so id like to know how much ill be spending in these upgrades.

I'd say a Super HX40 is a prefect candidate for you. It is a perfect towing turbo, and with the 16cm housing, there should be minimal lag. Much less than the 21cm Dodge blessed us '91.5 and '92 owners with.

A Super 40 can be has for under 1K new, and I've seen them go for around $500 used, while a new S300 variant are is usually well over 1K (the 62/71/14 flavor.)

A set of 370's should do well with the Super 40, and still stay cool, or you could go with a set of 6X.016's and mild pump tuning and still keep her cool. When your not towing you could turn the fuel screw back up, and have fun. When you need to put her back to work, turn the fuel screw back down.

If you have an automatic, plan on trans upgrades as well.

Edit: If you just want to get rid of lag right now, you could spend $200ish on an exhaust housing, either 16cm or 12cm and get rid of a lot of the turbo lag.

[TTipswprd]

nope i hate those autos. i got the 5 speed. now then with that done learn me on injectors please:thumright: dunno nothin really about injectors or the terminology anyways

[seeker1056]

370's have no place in a 1st gen - they are smoky, hot, n all around useless
POD's arent much better

spend the money on a set of proper edm injectors like a 6x14 or 6x16

deals can be had for as little as 600 for new and used better yet

define laggy, and unmannerly? I have run an hx35, twins, a Prostreet66, and now a Pro52

The twins spooled the best at around 1600 rpm or so, and my pro52 would be the next best at 1800 rpm and it is a 71mm turbo, although I do have to say my head is ported so it does make a difference on the spoolup

Timing, fuel, exhaust all have a bearing on spoolup

there is no single "best" setup as all trucks are different and so are the drivers, and what is acceptable performance for oen is not necessarily the best for someone else

[TTipswprd]

I understand that evvery driver and their truck is differnt but im tryin to upgrade my truck in the safest way based on my limited knowledge of these things. thats why im askin for input from everyone who knows more than me.

[TTipswprd]

what would be a good set of injectors to go with, 30 hp?

[Richie O]

If you ask 10 different people you will get 10 different answers. I have stock 4x.012's in my 89. They make good power compared to your stock 6x.009's that came in the factory cooled trucks. I put 6x.016's in my 93 because I was not happy with the stockers. The 16's are hazy at idle and put out some pretty black clouds when pushed. If your after mild horsepower get a mild sized stick. I here lots of people say good things about DDP3's for a little more lead in the pencil but not crazy smokey manners. I feel that stacks are needed for any big sticks that smoke badly.

[TTipswprd]

im not really concerned about lots of smoke just worried about keeping egt's in control. i kinda like the smoke i just think some medium injectors would give me a little more power and not alot of egt's. what are the 6x16's?
