6 x Xspurt 1000's and Proflow RB25 rail would be around $800 through me I think Mark, with all adapters.

Scotty - will that rail fit with the stock plenum? We are looking at going to E85 in the next few months, so I am interested in an injector upgrade.

I think so mate, the 1000's might be a tight fit, but the shorty 750's and 2000's are definitely no issue. I may even be able to get 1000's in the same shorter 1/2 length.

The SR20 rail kit I sell comes with a plenum spacer to help the 1000's clear the upper plenum. Perhaps you could do a similar thing to the RB plenum halves using bakelite or a similar insulating material, that way you would stop the heat transfer into the upper plenum also.

What paper filter are you using, I was told to be careful when use paper filter cause the ethanol can/does eat away the "glue" that holds the filter element to the casing

I'm using a speed flow 10 micron stainless sceen filter but the paper ones can go down to 5-6 micron which would be better

I am using twin Proflow stainless mesh filters, I haven't cleaned them in 3-4 years, since they were installed. I can't remember what micron they were...

The paper filters I have been buying were SX brand, suitable for alcohol fuels. (They have a similar 8an housing to the proflow/Speedflow style filters, and might just drop in to them.) I run the SX fuel reg in my car without issues so I knew it was good gear.

1250cc are decapped injectors. You're better off with the "1650cc" Bosch injectors which are actually 1550cc (people incorrectly advertise them).  They are not modified.

Tier 1 - ID  Tier 2 (½ the price) - Bosch Motorsport Tier 3 (aka shit and not worth it, also ¼ the price) - Everything else Genuine Bosch Motorsport '040' injectors with adapters for RB

If i was you i would use this Bosch 040 injector and something like the new Walbro 525 with a higher base pressure and you should be good to go.

A little Googling reveals Arram as a Japanese manufacturer who make injectors, throttle bodies and carburetors.

Yeah, just wasn't much info and didn't know if these were common in rb20's or not.

Most of the stuff says 550cc, so should be all good, cheers. ;)

Hopefully it doesn't cost you too much dyno time to set them up, it can take a while to work out suitable lag times etc with unusual injectors, and you are paying good coin for every minute it's on the dyno.

Unless you have the lag time report with them? Might be worth trying to source one.

Never knew injectors even came with a "Lag time report" lol..

I was going to get them tested and flowed before I chucked them on anyway. I think they're a little old.. :P

To save starting a new thread.....

Is the contents of this thread still relevant?!?!

As in are the ID injectors still worth paying basically twice the price or are the EV1-Bosch items closer to the mark 5 years down the track?

(Looking for 11mm units to suit standard RB26 fuel rail to get me around the 400rwkw mark on E85...)

ID1300x or 1250cc.....?!?

There are better options (than ID specifically) and have been for years.  You should perhaps PM Scotty to find out what he can do for you.

Basically, if you can get unmolested EV14 injectors in the size you need, that is best approach.  But even the ones that have been decapped are pretty good.

I had tried pming Scotty before posting but either his inbox is full or there's an SAU issue as i just get an error saying he can't receive messages, or something similar....

Cheers for the reply though....

I do have the 1250cc injectors that Kudos sell in my 'cart' but after reading a few threads on here and then googling I was having second thoughts....

Tier 2 (½ the price) - Bosch Motorsport

Tier 3 (aka shit and not worth it, also ¼ the price) - Everything else

Genuine Bosch Motorsport '040' injectors with adapters for RB26 manifold would be the go. I'm sure NZEFI sell them as a kit.

      R34 GT-T cycling ABS pump

      The team at OBD2 Australia are pretty good, shoot them an email and ask them. I've dealt with them before for work stuff. I'd be shocked if it didn't work, so long as Consult can activate the ABS. But you might need to use KLine for it which would be the stopper, as I don't think that piece does KLine comms.

      Yeah and hence my ghetto way of slamming the brakes, get the ABS to cycle, rebleed seems to be a sensible workaround.

      Hey! Happy to help. Nothing inherently wrong with the adapter, it's more so with Brett Collins himself. He gave me a lot of incorrect information when I was in contact with him and was extremely rude when I challenged him. He stated I could not use any aftermarket twin plate clutches except for his own, not to use the dush shield, bla bla bla and it was all BS.  Collins stated to cut roughly 14mm's off the housing, I took off 15mm to make room for the dust shield. I would confirm with whatever adapter manufacturer you're using.

      There's plenty of OEM steering arms that are bolted on. Not in the same fashion/orientation as that one, to be sure, but still. Examples of what I'm thinking of would use holes like the ones that have the downward facing studs on the GTR uprights (down the bottom end, under the driveshaft opening, near the lower balljoint) and bolt a steering arm on using only 2 bolts that would be somewhat similarly in shear as these you're complainig about. I reckon old Holdens did that, and I've never seen a broken one of those.

      Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go.
