LOL...does the PFc have a pre-set for 444cc injectors, If you need some numbers for the base tune then i can help you out with some of the numbers from my PFC.

Depending on the turbo you are running our numbers will most likeyl start to differ after 1600rpm.

I'm half way there.Rb20det injectors are out GTR ones in and now need to mod the plugs or get new ones,wire in the resister pack and get it tuned.I've been taking pics for you ChrisR32 to.

do you happen to have pics of the mod'd clip to fit the 13b injectors? Thanks

Its easy to mod the actual injector to be able to take the standard RB20 plug.

The only reason the RB20 plug wont go on is there is a small plastic protrusion in the Inj. socket.

This small lug just needs to be cut away with a stanley knife to make the std plug fit on OK - a fairly quick and easy fix. :)

Roy I have a series 1 RB20DET.The GTR injectors fit the RB20det rail perfect but if you look at the pic the bottom lug on the GTR injectors are off-set more and also has a lug on the inside.I was told they would need modding.

Great stuff, look forward to the end result!

Some pics are not that good.It's straight forward once the plenum is off and some tape is peeled off the injector loom.On the GTR injectors I cut off the bottom lug and the lug it where the plug clips(See pics)

I'll have a daigram up soon,thanks Roy :D

It idles and revs fine with the standard ecu but with the PFC it's very very rich and when ever I drive it I gotta put the injector value to about 650,thats still rich but this friday it's booked in to get tuned.

It was a pretty crude picture, but hopefully it helped. Good to see you had no probs installing them...can i ask where you scored your resistor pack from. If we RB20 owners can get a handle on a readily available supply of resistor packs then we are in business as far as cheap injector upgrades go.

Roy,

I have read up on the message you sent me a while back, and have had a good look at the picks, cheers R31 POWER!

Does anyone else have any other pics or info that would help? What colour is the power wire going to the injector plug?

I have a spare RB20 at home with the injector loom and injectors/rail etc still on it, I might have a go at installing the resistor pack on the spare motor and just swap the whole rail and wiring onto my current motor. Do you guys think this is feasable?

BTW - got my injector pack from Mark Tilbrook, spoke to him at a dyno day the other week, he told me if it works, make him a offer, so at the moment it hasn't cost me a cent :cheers: He was keen to see how it goes

Also, does anyone have a map for there PFC to suit GTR injectors yet?

Chris

It would be more agro isntsalling the new harness then it would be too solder in the resistor pack into your existing engine/harness

As for colours, i cant remember, if R31 POWER cant help you out with colours then i should be able to have a sticky at mien next week and tell you. When are you planning on doing it...anyway you dont really need to kn wo the colour, you can identify it by the way they are wired.

As for a PFC map, buy my TD06 and YES i do :cheers: ...otherwise i can help you out with some base parameters to get the thing to idle and run at low rpm, but i suggest you just get the car to a workshop ASAP...The PFC may even have a rough default settin for GTR injectors?!?! I havent had my PFc that long i cant remember :Oops:

That would be cool. I will try and have a look at the spare motor tonight and see what i can work out, if anyone knows that would be cool.

I bit of a base map for low rpm stuff would be cool, chances are I think my PFC is setup for bigger injectors judging by the numbers that are programmed into the fuel map, either way it will be re-tuned to suit, but it would be handy to drive it rather than tow it to the workshop!

Will be looking at doing it by the end of the month hopefully, whenever I can get some time off........:cheers:

Did you guys use the RB20 O-rings or the ones on the original injectors, or did you get new ones?

Bloody good thread this for RB20 owners looking at injector upgrades!!!!! Roy and R31, give yourself a pat on the back!

Id rather Ms Universe bat me off:thumbsup: . I had my injectors cleaned and flow tested, and at the same time new pintle caps and o-rings were supplied

Shit I was going to write what coulor the wires were but though they would be different.

I can't take credit coz it's all Roy,if it was'nt for his diagram he sent I would'nt have GTR injectors in.

I used all GTR stuff like o-rings and those rubber top bits coz all were new not so long ago.

Chris when you do put GTR inj's in there's a injector harness that unplugs from a plug at the front.It powers the 3 rear injectors and that air motor thingy.We cut the 2 wires going to that motor thingy and used them for the injectors.Read futher.

It's hard to explain but the power feed to the injectors go like this.The main power wire then branches to 4 wires and then 2 wires on that un-pluggable injector harness.So instead of running 2 new wires to those in jectors we used those air motor wires.Plus that plug could be used and it still looks factory.And those 2 wires from that air motor we joined to the same wires that are straight above it in the loom,god knows why nissan did'nt do that before LOL

I think I might of confused you Chris and if so tell me what bits you don't get.

I think I have got the general Idea now - correct me if i am wrong

Wire in the power wire for the resistor pack before it branches off into seperate wires. Connect the seperate wires of the resistor pack with the power wire going to each injector

Is this correct? Do you ahve to run new wires from the resistor pack to the injectors or will the old wire be ok

    • Hi all,  I am in the market for an R200 longnose diff out of a Z31 300ZX, or S12 RSX, DR30 skyline, or similar, in a 3.9 ratio.  Preferably a late model one with the M12 crownwheel bolts.  The only easy to find advert for one of these was my ad back in 2007 when I sold it on this forum.  I sold the diff as I had sold the car it goes to, but as it turns out, after 18 years I got the car back late last year, so now I'm looking for the diff !  If anyone knows where to find a longnose R200 LSD with the M12 crownwheel bolts, drop me a line at [email protected] - Bonus paid if soomeone comes up with the original diff (stranger things have happened !).  Cheers   Ben D    
    • Hi everyone, I used to post here a bit from 2004-2013, when I owned various Nissans, in particular my S12 RSX gazelle, which was sold in 2007.  As luck would have it, after an 18 year hiatus, the car found its way back to me last year, and over the past 11 months I have had the pleasure of restoring it with my kids.  One thing that I am after in particular is a 3.9 ratio R200 LSD for it.  I actually sold the one out of the car here back in 2007 , and it would be incredible if I could track down who I sold it to, so I can see how they have progressed over the years (and to be honest, to see whether I can get the diff back !).  Anyways, hi all and let me know "where are the R200 Longnose diffs all at these days ?  Cheers Ben D  
    • Arms will be the same as the G35 or 350Z, but as above, there was a change in the lower control arm where it connects to the ball joint.  That said, you can remove the ball joint cone from your old ball joints and fit them to the new ball joints.  To be honest, I didn't think the ball joints themselves were different. The main ball joint is a bit awkward to replace, you really need to remove the steering knuckle to press out the old one.  Some people have used tools to remove it in place, but it just seemed too hard to get to. If you are going to press out/in that ball joint, then you may as well just replace the bushings in the LCA and the compression rod.  You can buy the compression rod bushing from Nissan, but the LCA bushes, you will need to go aftermarket. Much cheaper than buying the whole arm.
    • Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
    • Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)
