bahhh go to buy new rods for my 1.6td build from rosten and there website is inactive. not sure if they are done or just down. just in case, who else makes good quality rods for a 1.6? im aiming for 200+ hp and more torque so id rather upgrade then blow a hole out the back of the block and have to buy new pistons and bore out another block.
Also, i am trying to figure out what to do for injectors. As far as i can tell i need to upgrade them to flow more. 35 psi is a lot for stock injectors
Thanks, Lee

the stock rods are good for whatever power you can throw at them..
the HEAD is the weak point of these engines, as has been stated a couple million times

No need to upgrade the injectors--that's the beauty of the pintle nozzles. The injectors are capable of flowing crazy amounts of fuel in completely stock form.

missed that part the first time around..
the injectors in the engine already are capable of flowing MORE FUEL than the engine would ever be capable of burning..

yea you are right about the head being the weak point, start warping at about 40psi (depends on turbo choices and such) but i have also watched a 1.9 walk the crack out of the block when he stepped on it. blew 4 blocks up before it would be cheaper to buy a girdle.
If the stock injectors are fine then why are the gtd ones bigger? and i have also heard people using mercadies injectors...?

You'd only need the merc nozzle when you are getting up to BIG power, like near the 325 HP range. That's drag racer power, more than a performance street car needs. That's when you have a stack of heads ready for WHEN the head goes . . . again! Just make sure your stock nozzles flow correctly, and replace them if they don't or if the drip.
Put the money into your PUMP, not the NOZZLES!!

Oh I already put money into my pump haha. Gave it to Giles and got him to rebuild it for 35 psi. He said ok an did his thing. 1600$ I have my pump.
I'm going to at least get my injectors rebuilt. But what about gtd ones?

Nah, just get them rebuilt. The stock nozzles,as said, WILL hold up to an fuel you put through them. Addition of power fuel-wise, especially with a Giles pump, is better accomplished by the tuning of your fuel screw.

I don't want to throw a wrench in as I don't know if it is anything or not. There is an obvious difference in the GTD and standard nozzles as Giles told me the price is almost 100.00 per GTD nozzle. My engine lost a precup and I was running more power than stock. I had regular nozzles. I do not know what the difference is or if there is any difference as the GTD was only making a few more hp than the regular TD mainly due to the intercooler. But if they are the same why would they cost 4x as much as regular nozzles? Do they offer a slightly better spray than our standard? I don't know, but VW being VW and over engineering everything I would think that they were thinking about it for the higher performance engine. I have thought of getting some GTD nozzles and doing an A to B comparison between the 2. To see if there is any change at all in performance to settle this once and for all, but around 400 just for the nozzles then to have them calibrated is out of my curiousity range. Maybe I will someday, if my cylinder head isn't going to be done until 2020 or something I may have time to save for them. I have a brand new set of standards ready, so I am 1/10th the way to doing it.

Stock 1,6 NA injectors are dyno proven up to 250+whp. Stock rods will bend with lots of low end torque, high hp does not. This has be seen several times. My friend had my old 1,6 NA rods in his gasser 6-cyl mercedes, those bend at 580hp/720nm

OMG... these rods REALLY ARE tough as hell...
how many RPM do those rods see in the gasser @ 580hp?
the HEAD really is the weak point of these engines!

~6000rpm, not much. I don't think head is weak point, I´ve never had any problems with head or gaskets, nor my friends..With 180-240whp IDIs...

i think the head is just fine until about 300hp or so..
then it starts to FLEX..
