I'm interested... Need to sort some funds out, but if the timing is right I'm definitely on the list to get some of these..

Hey Guys,  

ive organised some sweet prices on a set of 6 x 540cc injectors which are straight fit into the rb25det fuel rail.  

These injectors are high impedence, side feed and same size as stock, so no problems in fitting. They are manufactured by Hitachi Unisia Jecs(same manufacturer for Original injectors for many Subaru cars, STi, Nissan, Nismo, Apexi, HKS, Power enterprise..etc)

The clips are slightly different, and either can be modified quite easily ive been told to fit into our plugs, or we can purchase correct plugs from mitsu electric.

These are ultra atomization technology injectors that assure the very fine atomization of fuel, making your idle stable and providing impressive fuel efficiency.

The injectors flow:

470cc/min at 38psi (standard fuel pressure)

500cc/min at 45psi

540cc/min at 52psi

575cc/min at 60psi

What this means is that to get the correct cc out of them, you will also need an adjustable fuel pressure regulator, but I have been assured the injectors are designed to run this amount of pressure, so they will be fine.

Retail Price on these are $1060 for 6.

If i can organise 10 sets, then the price is $520 = postage ($10 approx?)

So comon guys, this is our chance of gettin injectors finally cheap. Excellent quality injectors made by the same companies as the more expensive ones.

Beautiful timing, put me on the list as a definite (assuming, of course, that all technical stuff is easily resolvable. :cool: )

Only need one more and thats the ten. :P

Count me in.

This is a fine price for direct fitters.Enrico can you tell us if the plugs are a fit or not.

Give me your email so i can contact you.

Like i said im not closin the group buy til next month, + if we get more ill try get more off the price...

Im still waiting for info on the plugs guys.

Are there any other questions needed to be asked?

Enrico - You'll be able to easily answer this one for me. I have stock fuel system running on my R33.. When I want to install these and have them running at an optimum rate, will i need to get a fuel pump and upgrade my fuel rail, or just the case of installing a fuel regulator?

I've always been confused on this point... Otherwise sounds good.

The fuel injectors can flow 470cc at stock 38psi fuel pressure. U will not need to modify anything to fit them, however it is very unlikely that the stock Fuel pump can flow that much though. Therefore to get full usuage out of these injectos, u would need to purchase a bigger fuel pump aswell, so that it can flow enough fuel to the injectors

Hope that makes sense.

Enrico, I was looking at installing these myself and there are a couple of consumable parts that need to be replaced such as o rings and insulators when the old ones come off.

Would you know where I could get these from?

Are you going to have these parts installed or do it yourself?

PM sent

Trust33:

These injectors are brand new, and disigned to fit in the std RB25det fuel rail

ie: High impedance, side mounted.

NOTE: I do not believe that the std ecu (alone) can handle these injectors. You may need a "piggyback" unit or an aftermarket engine management.

Enrico:

Is your contact/supplier able to supply 700cc (or greater) LOW impedance, side mounted injectors?

Just that i am running a wolf 3d and low impedance injectors pulse quicker than high impedance, when idling. The wolf can easily controll both, i just prefer the advantages of the low impedance.

i will find out for u Al.

Im still waitin on the info about the clips and plugs.

Also Im not sure whether the stock ECU can handle these so its best u do ur own research. However if u were still using the Stock ECU id think there would be no need for aftermarket injectors.

Correctomundo!

People with stock ECU and even S-AFC should tread carefully.

It works but it won't work as good as people make it out to be.

Fully programmable ECU is what you need.

Once you go 550cc/AFM, it's time to think ECU.

    • I have seen a case where the starter motor shorting against the casing caused a massive voltage drop + so much EMI that it caused all the sensors to spew garbage data at the ECU. Test the battery to make sure it has acceptable CCA/capacity first, I have gotten "brand new" batteries before that couldn't even power a 10W light bulb without dying probably because it sat in a warehouse too long without being charged. Only easy way to diagnose this 100% is put an oscilloscope on the battery and also look at key sensors to see if there's any clues.
    • There's a bunch of smaller shops that don't quite attract Singer money but are still hiring from that same pool of labor. Those are the body shops that you go to when you can't afford a Singer, but your old Porsche needs some serious bodywork. You can't exactly take those cars to the usual insurance body shops. When I say restomod, I mean they'll do something other than 100% OEM/OEM-equivalent aftermarket parts R&R. In the Porsche world this would be stuff like taking a 50k 964, doing a bunch of deferred maintenance/unwinding the nightmares the previous owners did to the car because a lot of people that own these cars tended to be penny wise, pound foolish types, then maybe some relatively simple off the shelf modifications to things like suspension, transmission, engine, headlights, etc. and you've spent 130k USD. When even the worst houses in the poor neighborhoods are worth 1M USD and the nice houses in wealthy neighborhoods are worth 3-10M USD suddenly 130k spent on a 50k car seems cheap.
    • Hoping to get a few ideas to help troubleshoot this issue, I'll try to keep it short.  A mate popped the motor in his 2018 LDV T60 with the 2.8 turbo diesel motor. He swapped it and I was his phone a friend when he got stuck.  The new motor is in, however it won't fire. The battery is literally brand new, when you crank it the volts very quickly (say 2 seconds of cranking) drop to 8 volts and the engine stops turning over. Watching the belts, I'd say they move about 5cm before coming to a stop. We put a booster pack on, no change.  The only potential issue I'm aware of is, when we pulled the motor the grounding strap was still attached. The strap copped a thrashing before we realised what was going on. It looks okay-ish but it's going to be replaced to rule it out.  The main challenge is, I wasn't there for 90% of the work. This is his first time doing any major work on a car and he was learning as he was going. He thinks everything has been put back together properly, however I'm not entirely confident that this is the case.  It would be good to get some ideas about what else to check. The car isn't spitting any codes so that doesn't help.  I've attached a photo, because why not lol.   
    • I mean an N1 came with a minimal paint thickness compared to dealer models. It’s probably had a ton of vinyls and stuff possible a race paintjob or two over the years. you don’t buy an N1 for its stunning good looks or comfort 🤣 you buy it to send it and measure how much air you can get on the hill at Bathurst
