I know this is probably an age old question BUT I am going to be ordering some injectors here fairly soon (probably before the 16th) and want to know if I should go with the 435's or 370's from New Era Diesel... I will be putting in a new clutch also so that is not a concern, my biggest concern is which would be more driveable with just a stock turbo for the time being and then later with a set of twins? Will they both be able to net me above 500 RWHP with an HX35/B2 twinset without having to flow the pump? If not 500+ then what could be expected? Also would I be able to tow 10,000 to maybe even 16,000 lbs with either set, especially with twins? I would really like the 435's but if they are not streetable at all then I don't feel I should go that route obviously... Any opinions or first hand experience with either set of injectors would be appreciated, and if you have any suggestions let me know Thanks!

I got the 435s and they are a good injector if your on a budget. If you can swing it, get DDP4s or Hot Rod 370s. Dont get me wrong, I like my 435s, but I would prefer something thats a bit cleaner. They smoke quite a bit and haze at idle. Which in some cases is good for those pesky tailgaters...

With your twins you should be able to cool things no problem while towing with 435s. I doubt that you would have to do anything to the pump.

I have PDR 370s and u have a twin truck to mine... sweet....

and they are not enough injector to push these twins to their full potential, With some 435's, or some DDP 4's u will have some seriously nice injectors, add some laser cuts to them and ull be good to go..

Im actually in the same dillema right now, not so much so, im savin for some DDP 4's then im addin some LC DVs.. with 370s and 181 DVs which come stock on our trucks u should be well in the upper 400 horse range maybe even the 500's, with the B2 under it, however i plan to redyno soon, so just keep up with my sig and ull be good to go...

370s are not a bad bang for the buck tho, nice kick over stock and i drove around with them for 18K with a stock turbo and 14 cm exhaust housing, they are smokey if you get on it tho, and do slightly haze at idle, but with ur accleration control u shouldnt have problems driving them, oh yes, i drove them with a stock clutch for about 13K as well...

Towing? no super heavy loads yet, just a small BBQ pit, and a 20 foot gooseneck with 5 horses on it, NO issues with EGTS and power on tap to spare, consideration of a valet switch is in order tho due to the engine temp being a little warmer than id like.. however its still in the 90s here.... other than that, twins rock for loads...

You need a larger turbo or twins before you install injectors that big, the EGTs are going to go through the roof

I noticed that as well TxDiesel, thats pretty awesome! I even put on towing mirrors tonight, lol. I figure the EGT's will be pretty high but I was hoping that if I pulled my #100 plate all the way back or swapped it for a #10 that they could be somewhat controllable... Maybe with advancing the timing as well. I have literally everything needed to fab up twins (even the bottom turbo, which is an HT3B at the moment) I am just lacking either A: The down time for my truck to take it apart for the actual fabbing process or B: Another HX35 to use strickly as a mock up turbo to build the twins using the stand that I made that has a spare manifold bolted to it .

I talked to the guy at New Era today and he told me if I bought two sets at the same time (my buddy is going to get some for his 24v) he would reduce cost slightly and if I was to get more sets afterwards he could help even more, so I will probably order them soon. Could I somewhat squeeze by with the 435's for atleast a few weeks if I pull the plate all the way back, bump timing to a safe level and adjust the starwheel?

I have gauges on there way so friday I should be able to put them in (I'm off work and no school) so from then on I will be able to monitor my EGT's and what-not (so I don't blow anything up, lol). My biggest reason for wanting/needing injectors soon is because mine are leaky so the sooner I get injectors the better I figure. Thanks for the help so-far dudes!

i love my pdr 370s with o plate. mine do not haze at idle. they will get hot at full throttle. went through tn. emissions with a .03 surprised me.

TxDiesel007

U should be fine for now..

Like i said, i ran 370s for a while with a stock turbo, and as long as you watch ur pyro, u should have no issues whatsoever with egts and what not. Even with the 100 full forward, u can still control egts with ur right foot, I did happen to find tho, that the best position for egts on my truck was a 2/3 forward plate, half starwheel and a full forward AFC, with a stock turbo and it kept my egts managable and my max boost at about 40 psi or so with a blocked wastegate, 32 or so with it running straight.

If your injectors are leaky tho, it might just be the o rings on them, but hey upgrading is a good idea, But trust me, fuel is nice but when u add air to it ITS SOO MUCH BETTER.. u might also wanna consider an intake to help you slightly with the egts...

again tho, feel free to pm me if you have any further questions, ill be more than happy to assist you..

I ran the 435s on the stock turbo for a month until I got my 64. EGTs would climb pretty quick, so you had to be on the look out.

Ok next question; for a first timer how long does it take to swap the injectors? Are there any write-ups on what exactly needs to be done? I am going to work on the twins and getting them fabbed just using the HT3B I already have for now, later I can go a different route if needed . I appreciate everyone's help!

I would go the 435 route.

I'm running those with a HTB2 64/14 and a tuned pump (laser cuts, #100 and recalibrated). The single charger will clear the smoke quickly but it is hazy at idle and on easy take offs. It will easily keep the temps in check.

If you go with twins you will want to turn up the pump to see their full potential. You'll easily be able to keep the temps controlled with the twins. Just take it easy until then and slide the plate back.

Chuck at New Era is a good guy to deal with too.
