Whats prob the best to go for with a t34 (when ive got it rebuilt) dark greens or a set of Greys. It will have a 500 cooler, 044 fuel pump, 3 bar, pectel board and chip to suit

 

Neither,go for 55lb siemens blacks m8.

 

in the words of Frank Abignale 'i concur'

 

403 are old hat now and the modern injectors give a better spray pattern - given the choice it would be the siemens.

 

But if you had the choice of the both what would be better? As the boy im gettin them off is givin them to me free as he owes me a few favors. Or would i be better off gettin Greys, stickin them on the bay and buyin some seimens blacks? What power are the blacks same sort as the dark greens? Cheers for the above tho!

 

what power do u want..???......on a t34.....greens 350+ greys will do about 440 (but not on ur turbo)....nothing wrong with any of these injectors.......better off asking ur tuner what would be good for ur set up............

 

i tried phoning him earlyer but he is pretty snowed under with alot of work, id be happy with 350 but was mayb thinking if greys then i could save up my pennys and get other stuff done, but need to concentrate on my turbo being rebuilt first

 

Pete, won,t Greys be pretty much maxed out @ 440 though i,d imagine...?

Jody, go for Greys and a .48 housing and have yourself a nice Punchy Road car, i had that on mine and it was superb, made 362bhp with similar torque.....

 

ive got the .48 housing and im feeling that setup and figures

was it still on the relible side or was things getting a little bit too much for the standard parts left?

 

.......fuck knows whats happening with what injectors can and can't do at the mo........look at mine on light blues.....and Nash's on greys.........but normally yeh 440 is flat out on greys.........

 

55s are bigger than greys,

i truely belive our 55ib T34 package is the best ever for a road car, endless torque from so low down!

 

No, it was VERY reliable, i drove it hard and it never missed a beat.

I had it live mapped by Karl, block was wire-rung, Radtec Radiator, 500 cooler, Greys bla bla..

I,ve always said i PERSONALLY think a well set-up T34 Car no matter what the housing makes the best road car imo, i prefered the .48 housing as i just wanted a lag-free punchy car and 360+bhp was plenty for me, i,m an ok driver but believe me it kept me on my toes..

 

thats soundin just right for what im lookin for. Thanks alot everyone for your input. Now to start saving lol

 

got greys an t34.48 on mine holding 28psi, perfect for the road

 

Yep, cracking for road use, there,s not alot that bothers with this set-up only the odd Evo and bigger power cossies.....

 

cracking turbo.......but they kill 4x4 boxes..........

 

I concurr- I absolutely LOVE the low end torque from this conversion on my old taxi

 

them rollers you were on that day were a bit optimistic tho...never seen or heard of a car doing that on light blues...good power graph tho..cheers danny

 

I beleive the topic starter asked greys or greens not any other injector?

IMHO greys, they can be mapped to perfection by the likes of NMS.

 

Greys, T34.63. 34lb of boost and fuuuuuuun.

 

Think im defo gonna stick to the Greys coz im liking what im reading from everyone that posted. Cheers fellas, jody

 

....funny u say that cos didnt belive it either till i talked to 2 other very well know tuners that said if the car was running spot on it would...and does that mean the other cars were wrong aswell....???....ported heads,bigger injectors,bigger turbos making not that much more really.........

 

Not strictly true about the Greys - they are an odd injector, where one can vary quite differently from another. Officially they are rated at 501cc, or around 50lb, but the set i have for instance all flow over 600cc at 37.5psi. One of the reasons why off the shelf chips for them can be a bit dodgy.

go for greys over the greens - i got bored of my car after a while when on greens

 

The NEW rating will be lower, they invariably supply more as they gum up a bit, that's why the ones I have cleaned always flow to new levels, older used ones tend to flow slightly better.
The comment about siemens being a better spray pattern, although banded about by a lot, I'm still waiting for evidence from back to back testing, at the end of the day it's the engine that decides if it likes the "better" pattern it may not.
Go for greys if they are free, I had greens 803's, these were on 80% duty at 300bhp, but that's real power, not fairy story.
I run greys with a slightly modded head, std cams, and a T3/34 a T3 comp housing machined out to take a T34 trim, std .48 ex housing.
My last MOT gave 0.97% CO, and 137ppm this is on a 160,000+ miles bottom end/pistons/rings.
This is NOT on closed loop, as I don't believe in it, a recent trip to Scarborough from east anglia returned 38.8 mpg, this was along the notorious A15 etc route, not A1 steady speed, used 47 litres for 402 miles.
If it's mapped correctly it will drive perfectly, I always go as low as 1000rpm in town even in 4th it pulls hard enough for town traffic dawdling, but 2K upwards is punchy.
Whatever you decide, the best money spent imo is with a decent mapping session, instead of off the shelf chip, the chip would do the job, but the mapping session could yeild so much more.

Good reply that Tab...

I,m moving upto Greys when i go for Karl,s Gunship conversion, i feel they,ll cope better than the 803s tbh...

 

Know the feeling....

 

that is a spot on reply there but the siemens are so much easier to map so they make life alot easier for the mapper and then costing you less..this guy cant go wrong as hes been given them but if i had the choice it would be the 55lbers al the time cheers danny

 

iv used light blues alot and on different specs and never seen that power before,im not slating your power just saying the rollers are being optimistic...so yes everyones elses would also be over...just put it on another rollers soon will tell you..if your ever down my way il put it on mine for free...cheers danny

 

......lol...it has been on the different rollers before......it made 407 @ 25psi......then 420 @ 26 psi.....this time it held 27 ish and made 427.....this was the first time my car has made full boost on the rollers....even hit a 31psi spike....which it's never done on a R/R...............and thanks for the offer because all i ever wanted was a "full boost" graph.........ps Ahmed doesn't belive the power it makes either

 

Pete, i also heard Ahmed hates mapping Greys with a passion, my old 3dr Leigh bought off me is with him at present and he,s asked him to consider Light Blues...

 

.......next stage for me would be either 8 injector or pectel ecu and seimens......but i think both of them options will cost ALOT............so my next project might be "save weight" and make a FoCos...........same spec engine 4x4 focus crack...

 

Tuners who say they hate to map greys means they have no idea on how to. In which case find a new school mapper!

 

.......shut up...........

 

lol...ahmed cant map now!!!pete that is great power and is consistant with other rollers...i wouldnt bother changing anything unless you ever go for say 500+..i dont think many tuners would believe it but hey its defo consistant...lol...cheers danny

 

cheers Danny.........but i still want my free R/R....................

 

another reason for that is because he has so many realy nice maps on light blues hence saving lots of time with a very good base map...before all these siemens came popular alot of tuners prefared light blues to greys..danny

 

If I had to buy new, I would not buy greys as they are no longer made, and bosch has only 600 injectors left(greys), so will all the spares dry up in a few years ?
Of course any presently made injector if having to buy as opposed to being given free has got to be a better bet.
If I was using someone who shied away from doing something like this, you'd hear the door shut as I left.
I have a soft map for bad conditions, which is around 200bhp, but copes perfect on greys.
I regularly do 6-8 hours of city work not over 1500rpm, doesn't miss a beat ever, the bottom end delivery is defo better on greys than dark greens.
I'm running mine with resistors, but didn't to start with, as I forgot!!
Amazingly the ecu coped perfectly, but as higher sustained loads the injectors were overheating and shutting down.
Still whilst trying to find this elusive problem I replaced the fuel tank, pump, fpr, etc, so have a few good spares now!!
It was only by chance I found a note I'd written about Roosie owing me 4 resistors that I remembered, and he still hasn't paid for them, tight git that he is!!

I,ve NEVER had a car using Light Blues Danny, what power level are they good for safely?? i know Pete,s is 400+..

 

.......ment to be a good 400 bhp injector.....(think i got doddgy ones)
