Injector decision
 

I'm sure there is another thread on this but I'm going to make an injector purchase soon and cannot decide which brand. BD 60's or DDP stage 2. I plan on an hx35 swap in the future.

why limit yourself to only those. there are many other companies out there that offer the same quality for in most cases much less money. and i would do a 5x12 injector

Check DFI.... we carry them

What is a 5x.12 as far a hp gain?

They are advertised as 40 or 50 HP. 5 holers are a good all around choice. If your looking for something more suited to low end pulling power and less concerned about top end street racing, check into 6 or 7 hole injectors. I have a set of 7X.010" in my work truck. The low end is much better than the 5X.012" it had before.

I want low end, speed does nothing for me. I want a truck that I can use around the farm to pull cattle and equipment. However I am going to college soon and it will be on the interstate some. What setup would you recommend?

If you can spare the down time and want to save some money, have your stock injectors reworked. Have them rebuilt and the holes opened up to .011. Stay on the mild side of injection pump tuning and invest in the M&H dynamic timing device instead of bumping timing. I would also recommend a 60mm compressor upgrade for your turbo. I would leave the exhaust side alone. Smaller housings may spool faster, but the trade off is higher EGTs and that is something you don't want in a towing rig.

i like this comment other than the turbine portion of it. the smaller housing are for quicker spooling. this dramatically aids in towing and reduces smoke. the addition of a wastegate eliminates the reason to have a massive A/R non gated turbine housing. after the 60mm compressor upgrade you are $300 deep into an inferior charger when compared to a good takeoff hx35 or he351 for the same money. i would definatly discard your current charger for a newer style shock charger or much more desirable frame s362 with a 65mm turbine. i really liked my 62/65/14 for DDing and towing. it was an AWESOME charger for a peppy work truck.

Thanks guys that was a big help. What do y'all think about Sdx injectors?

i dont think they are in business anymore? at least that was a rumor i heard around town some time back. that said i ran SDX 5x12's in my 95 for prolly 3 years with nothing but good to say. i pop tested them before i sold them and they were all within 5 bar of each other.

I believe SDX split up and, Chris, the guy that did their injectors started his own company, DFI. I've been running the DFI 5x.012 SAC's for about a month and I'm really happy with them, I picked up quite a bit of power, mpg's, and they run cleaner.

What supporting modifications besides a turbo would I need with 5x0.014's?

ide run an electric lift pump and put a gov spring on the pump myself. maybe a fuel pin. the truck still needs to rev out to make much of any power. so do a few things that help in that department.

I will disagree with you mainly because I've run both a modified H1C and an HTT 62/64/14 on the same truck with the same injectors. The HTT has been harder to keep the EGT under control while towing.

I have the HX35 and 5x.012 injectors. Got it all used with a spare VE pump for $300. :jump: The 4" DE exhaust kit cost me more. :humm:

Way less smoke, pulls great, spools fast. Love the turbo whistle. Towed a few things and very manageable. Only gets hot when lugging it.

Governor spring is next, and a low pressure piston lift pump.

Will an hx35 push enough air for 5x0.014's?

That's kind of backwards.... Fuel makes the turbo work. ;)

Stock non-intercooled injectors can supposedly max out an HX35. Your skinny pedal and fuel screw determine the fuel rate through the injector holes. If I was buying new injectors, I would make sure they are at least large enough to run with a 14mm pump head.

its going to get hot with such a little turbo.

What turbo would y'all recommend? And what is the flange on a stock turbo?

I still recommend the Hx35 or HE351cw since they can be had very cheap used and spool very fast (excellent for stick shift). You can also change the exhaust housings affordably if they are too tight/hot for your liking. These two turbos use the same flange as the stock H1c.... Not sure but it might be T3 flange.

its a t3 divided, you can get a non gated 16cm housing for the hx but you are stuck with the 9cm on the he351. i would also recommend the hx,he351 or my personal favorite a small s300 in the neighborhood of 62/65/14 way superior charger over the other 2.

kinda curious what your thought is on a hx35 with 60wheel upgrade (hx40 7 bladewheel) and a 14 exhaust housing (gated). with 5x12 injectors..:c:

not worth your time. the billet 6 blade hx40 wheel is better than a 7 blade. but all hx30,35 and 40 turbos have the same shaft diameter. that said when you put the most aggressive heaviest comp wheel on the small shaft you are flirting with a bomb. like i said before an s300 is a much stronger charger with a very similar personality to a hx35 in its smaller form. its larger variants can be a pain to drive around. an s3 is a much hardier charger with way more potential than an hx35,40 or he351 could ever have. if $$$ is tight that do an hx with stock injectors if your wife will let you spend a little, get a decent set of injectors and an appropriate sized charger.

well I already had the 5x12 s in and have been happy with them.. I did the 60 comp. upgrade a while back and it made a huge dif.. I picked up a wastgated 14 and put it on since my last post.. not sure what to think about it.. boost is lower and egt are up a bit but I need to adjust my boost elbo.. was kinda curious if the 14 would cool things down and kinda undecided at this point... maybe it will get cooler with a little more boost with the elbo adjusted???? just looking for input.. didn't mean to intrude on the thread guys!!:c:

Couldn't hurt. I have the stock 7-blade wheel on my HX35 (01-02 vintage) with those injectors and I like it. Stock 12cm gated housing. Haven't opened up the fuel more than a couple turns yet because my screw threads are kind of mangled still.

I did drill a 3/4" hole in the divider, and it has an adjustable boost elbow (maybe I'll have a clue what it does after I get a boost gauge).

So today I had the bright idea of switching turbos. School is out and parents are gone for a week, a sick and anemic 2nd gen feed truck sitting in the driveway. Swap hc1 for hx35. Any comments?

hook the wastegate up and enjoy

How bad will the 2nd gen run with the smaller turbo

---AutoMerged DoublePost---

And how do I put the first gen turbo on the 2nd gen? (Waste gate to no wastegate)

they move the same amount of air roughly. the benefits with the later model charger is the smaller, gated housing aid tremendously in spool-up time. all you do is run a boost line from the intake side to the waste gate actuator and the gate will function as designed. factory they build 17-19psi before the open. and hx35 is a bolt on upgrade, no mods needed

So the hc1 will work on the second gen

The downpipe has to be moved back 1-2" to fit the HX35 because it is a bit longer.

sure it will. those turbos are essentially the same turbo just different turbine housings. the old h1c's had 50mm compressors and the later had the same 54mm compressor as the wh1c's and hx35's

this should be close dont quote me
old h1c 50/58/18
newer h1c 54/58/21
wh1c and hx35 are identical shaft wise @ 54/58/12
the difference is the last number which is the volume of the turbine
