"you're taking things out of context."

Absolutely not! ID is NOT the only company that does that thorough of testing when MODDING injectors and if you are going to imply that all modded injectors are not good than don't defend ID, or differentiate and accompany what you are saying with "if done correctly" because witchhunter for one off the topof my head uses the exact same procces described on the ID site. I have personally seen cars on witch hunter injectors and garage work bench injectors run and be tuned well. I never said all modded injectors were decent, in fact I even said that you must make sure they are modded correctly and the result is good. I have not only talked to several tuners (be it Subaru tuners but tuning is tuning) as well as have personally played with my friend's maps who also tunes and is running a hellacious custom setup on some modded WRX topfeeds with absolutely no problems. Once again I never said ALL modded units were good I said its something to look at because most of the injectors sold by PE, NISMO, RC, and ID are actually modded units, its just done right. so why would I pay 3x the price for something I can do some legwork on and get an absolutely equal product as well as be a part of the process.

Before I have to go get the flame suit: I am by no means talking badly about ID or NISMO or PE or RC or any of the other countless distributors. What I am saying is that I know their dirty little secret and because I do I would rather put my money elsewhere and save by getting it done by an independent shop (reputable of course) out of good units and take part in the process not only because I want to see with my own eyes that it was done correctly but because I personally enjoy being there for it.

In closing to back up both Vulcan and Tony: I have seen numerous instances of idiots using fat cutoff wheels to chop the plates of the ends of injectors not get them tested put them in and BOOM! Don't do that! Modding injectors yourself or taking them to a good qualified shop is a viable alternative to spending bookoo $ on new units especially when the difference in cost is 2 or 3 fold.


Sorry about the rant, and what we did to your thread. Its knowledge on the subject take it how you will :inoutgay:

In all seriousness, the main thing to look at when getting injectors modded is HOW they are modded, if the caps are drilled, I'd stay the hell away but if the caps are cut I would want to be present during flow test to see the spray pattern, if that and flow volumes check out there is no reason not to run them. Once again that article on the first page ONLY covers Drilled-out units.
to be honest guys that just makes me nervous to drill/cut (what ever but to mod) the injector :/ if i did do it i would have to have someone here that has done it and ran it before on their car

Specify what setup you are talking about and I can try to give you more info.
I'll be that guy; I would not use flow "modified" injectors. The link on the first page explains why.

For the GT28RS, either the Z1 kit or JWT kit, I'd consider either the Nismo 740s or the Injector Dynamics 1000cc/min injectors with the BDE top feed rail. Do not get the Lose Factory rails, there have been too many issues with their install from everyone who's bought them. 740's would be fine with meth injection and pump fuel or race fuel, but if you're running just pump fuel, you may have headroom problems. At that level though, you may need to consider an inline Bosch pump to boost your fuel pressure. You can email Greg at Specialty Z for more info on that.[/quote]
again, second to everything this guy says ---- what some people also do op, is run dual-oem fuel pumps, they're very high-quality (superior to walbro fuel pumps).
the hks front mounts aren't the best, i'd go with aspec massives smic's or the tdm fmic.[/quote]

ok well right now you are looking at this:

sport 700s - 2600
injectors/fuel rail - 1400
harness - 500
front mount - 1000
piping - 1000
-----
6500... still need manifolds (well you dont really need them).. 700. then what are you going to bolt the turbos to? 3" downpipes are another 500. what are those going to attach to? do you have a full 3" system already? this doesn't include labor, or your rebuild kit. 6k isnt going to cut it man, not even close. not to rain on the parade here, but no way can you pull this off with 6k. i like your original idea of keeping the stock turbos and rebuilding, with some supporting mods, and making a decent amount of power.. and save to do the big job right.

Yea thats what i am doing i have no choice im going to save up and doing it right. Until my money is right then ill be getting all the parts. But Ill just be running a forged motor, stock breathing, stock turbo's, ect....

Im going to just run that until i have the money to do everything at once i'd rather play it safe than sorry

Since you're rebuilding/pulling the motor, do the new EFI harness now. I'd also eliminate the second bleeder point for the clutch. Replace your heater core hoses with the Z1 silicone ones, and flush your heater core while you're at it. Same goes for steering rack bushings, motor mounts and chassis fuel hose replacement. I think I posted a link to bi-metal spring fuel clamps that Nissan uses now, no more tighting every season. If not I'll post it again later. IMHO, do as much as you can now, so that you have less to do when you do have money for the turbo upgrade.

A fresh rebuild with excellent compression, new stock turbo CHRAs, MSP manifolds and a dual Selin intake will still be way more car than you have now, and will be very fun. You can run it at 16 PSI with a proper tune, and get close to 400RWHP with ICs and fuel. Save for your breather mods and do those eventually. Building in phases can be fun, as opposed to "zero to hero" (not that your old car was a zero). Don't get discouraged, rebuilding into a bomb-proof engine is going to be a very fun experience. Be sure to create a build thread :dblthumb:

Definately doing a build thread. Yes i am doing stages of the build hah this is obviously stage 1

But here is the issue i would need new style injectors so what should i do i cant get bigger injectors with stock turbos and i surely dont want to waste money on stockies.... Any suggestions?? Does anyone have some i could borrow, Ha that would be unbelivebly awesome???? I would go ahead and get the injector rail adapter (obviously)...

you could for the time being get the new EFI harness and cut the injector clips off your old one and splice them into the new harness, that would be the cheapest solution for the time being.

I ran 740's with stock turbos for years, no issues. As long as your ECU is programmed for the injectors you're using, you're cash money rekkids.

That and I got rear-ended. :frown:

Silver TTZ had 740s with JWT EPROM and stockers. No issues, great idle good power. Got rear-ended by stupid twizzat-smoocher, saved all my parts. Bought Black Z, blew driver side turbo coolant line, pulled engine, upgraded everything including lower plenum with 95 rails and my 740s, got Sport 500 turbos, got sideways. :chuckle:

never add it up... :tisk:

I already had my 740s, bought my 500s used with 6K miles on them, had my UR pulley, Z1 SMICs, 60K kit etc from my silver Z, bought the MSP manifolds, got the SZ downpipes used, bought the SZ tespipes new, had the RPS fly, got the Southbend clutch new from Zspeedperformance, ummm, already had the methanol injection installed, and did all my own labor.

To replicate, probably about $5K if I had to guess.

^ yep I keep track of everything as well, including future mods, sellbacks, and net. i could use some work in the future upgrades though.

Nice, I have one somewhere like that but I haven't touched it in years, just kinda stopped keeping track so I wouldn't have a heart attack every time I looked at it. Although I counted up how much I spent on my swap the other day and let me tell you realizing you dropped 6k on toys is an eyeopening experience.
