Will ess vt2-625 injectors work for for 650?

[ss540i]

So I’m planning on upgrading my ess 625 kit and I currently have the white injectors that were supplied with the kit. Are these sufficient for the 650? I know pulleys, tune, etc are also needed, but wanted to see what it’s going to run me to do the upgrade. Thanks

Injectors are also different and cost a lot i believe. Also the 625 kit was given different injectors though out its lifespan. So the injectors depend on when you purchased it as they are always changing the kit to make it better.

at the time i upgraded my kit to a 625, ESS sold me the upgrade with the bosch blue injectors. i know some of the 650 kits came with the blue injectors at one time, like stated above the injector colors changed during the evolution of the kit. the important factor is:

the tuner has to know what color and cc the injectors are, then tune from there. contact Benvo/BPM and he'll set you straight with questions and answers and the correct tune.

i've not come across a better customer service company in the M community. the builder of the system, not so much.

at minimum you'll need the blue injectors.

you'll want to weigh your options here:

purchase blue or black injectors (pre-machined for fitment) + 650 pulley (pre-machined) from ESS with the accompanying tune (they have different tunes based on injector size). it'll be an expensive package.

OR

purchase off the shelf bosch green injectors + spacers + your own 94mm pulley (will need to machine for correct offset) + green injector tune from BPM. cheaper route.

Thank you! I will get in touch with them and see what he has to say. Appreciate your help

What kind of spacers are needed for the injecors? Do you have a link to where I can find these? Thanks for your input, much appreciated.

I run green injectors with spacers from active for the fuel rail. And a bpm tune. No issues here. Car made 565 on pump gas with the bpm tune.

Wow, nice. 7psi pulley?

8 psi pulley and a smaller belt so no slip. car made that in 80 degree weather as well. looking to do meth next.

Are you using the stock crank pulley? Are you running a 94mm s/c pulley? I know some use 7 rib belt to avoid slipping but not sure if that’s necessary.

I'm running a smaller belt too, I'd love to discuss a meth setup with you .

stock crank pulley. no need to do 7 rip if you use the correct belt imo.

Not to high jack this thread but where you planing on tapping in the meth ?? Longboarder has a thread where he didn't make anymore power with meth. I'm thinking velocity stacks

Have you dyno'ed yet for a baseline ? Who's tune will you be using ??

There was a thread a few months back discussing the 94mm pulley upgrade. There are some mixed opinions out there on tuning, but I will say that based on my own research I would not use anything other than an ESS tune for an ESS kit. Now to be clear, I don't think there is any real danger in running someone else's tune. For me it's just a matter of peace of mind as well as principal based on history that many people disregard.

I just emailed ESS out of curiosity to see if they would provide a tune for a 94mm pulley. I suspect the answer in no as they would require the 7-rib belt system in order to provide the 650 tune, but we'll see what they say. Here's the thread I mentioned:

I think Longboarder pretty clearly debunked the benefits of meth on an intercooled system, or am I missing something?

Didn't know bpm would tune with meth on our system ?

Problem with your thought process. ESS will not tune any injectors larger than the blue injectors. Not sure what history are quoting as a number of cars that have been running for years are using tunes out side of ess.


longer boarder didn't debunk anything there are quite a number of others who have successfully made power after adding meth one to include 1sickm3 who made more than longer boarder as was one of the 1/4 mile record holders in a e9xm3. how you spay meth is what matters. If you are using water meth to bring down iats and you spray before the intercooler you wont' be doing anything it needs to be sprayed after the intercooler. If you are spray meth for octane you will see the increase and your car will continue to hit it's timing targets even in high heat.


Lastly ess is the only place you can even get a 94mm pulley from. so why you think they wouldn't tune their own product is quite confusing to say the least.

You know exactly what history I am referring to and even commented on it in the thread I linked. We aren't allowed to talk about it on this forum without having posts magically disappear so I'll leave it at that. I also specifically pointed out that I don't think there is any real danger to using a non-ESS tune. It's just a matter of preference and principal. Anybody who is capable of spending a few minutes on Google rather than an echo-chamber can decide for themselves.

I don't know enough about meth to comment on this, but nobody said anything to counter Longboarder's assertion in that thread: "The intercooled systems cannot rely on water/meth to cool IATs because the heat exchanger is in the manifold, which blocks the meth flow (heats the post-meth intake right back up if the water in the heat exchanger is hot)."

I have read other people ask them for a 650 tune without the 7-rib belt system and get turned down. That is all I have to go off of until they reply to my email.

Do you know if a new tune is necessary to run the 650 boost level (94mm) if injectors are not changed? I recall reading somewhere that there other differences in the 650 tune besides just injectors.
