The cheaper Rockauto Jag injectors are the same as the 30% uprated injectors.

Sometimes it's good to be a stubborn old mule.

The correct part number is Bosch 62120 right?

These are the tests on the stock Ford Fiesta ST.
What it all means is yes, the Jag injectors from Rockauto are the 30% up rated injectors.

BRAVO MATE. What a chronicled endeavor of grand proportions.

The price just got lower everywhere, I bet. Nice work Old Mike! Sounds a bit more that the small markup I hear some vendors talking about.

Just so you know, I bought a set of Jag injectors and the Jag HPFP, it looks like it will fit. On the XKR they use two of them, one for each bank. The next windmill.

What’s the deal on the Jag HPFP? Is it the same as whats being sold in the aftermarket or something that’s already known to work?

Nice work Mike! For the pumps, I think I found that the Jag pumps aren’t an upgrade because they use two smaller pumps vs our one ‘large’ pump.

Thank God you were able to draw a conclusion. I think we should find out what else our oil filter fits....

It just may. From what I understand the Xtreme-Di hpfp flows at 200 bar which is the same as the hpfp from the Jag. I think at one point pumaspeed was selling a bosch uprated hpfp and it looked similar to the unit that came out of the Jag and Land Rover, but I can no longer find it available on their website. There was thread started about it, which didnt gain much traction, because aux fuel.

I just bought the Jag HPFP, on paper it looks like it will fit, need it in hand to be sure. I think I found a place to actually test the Jag pump. XDI makes the uprated pump for $1300, the jag pump from Rockauto is $153

I just read that thread from 2018, I have the Jag HPFP on order, we will see once it gets here.

Sorry - I think my response stinks. My bad....

This search was short, Bosch® 66807 - Direct Injection High Pressure Fuel Pump (carid.com) Read down to the description, this is a 200 bar pump, cost $160. On Rockauto RockAuto $153 for same pump, Xtreme DI Ford Fiesta ST 1.6L - Xtreme-Di $1300.99 this is a different design, 200 bar, Puma speed used to sell it for $1300, no longer selling it. I have ordered the 66807, once I get it I will see if it fits on the ST. If I am reading the injector test sheet right, the Jag injectors max out at 150 bar.

Now the fuel pump! This gets even better

I’d love to run full E on a stock turbo FiST with a WGA. I wonder if the injectors alone would give enough flow. It would only be making maybe 240whp
