Injectors and throttle body

[10000_fists]

Went to some mechanic today an got a quote for Magna injectors(6 of) and a 70mm throttle body and the price was $340, 160for jectors and 180 for TB, do you guys reckon its a fair price cause i do.

[stocky]

i got my injectors for free. go to the wreckers and pocket some from an 89 magna. or see what paradox is doing with his old magna injectors.

if youre gonna get a TB, just get a v8 65mm TB. any bigger is useless because you will be restricted by the size of the elbow intake

What are the magna ones again? The bosch beige tops?

[stocky]

theyre the creamtops. i think they flow around 24lb/hr

i have them in mine. youre gonna need to adjust the tune a bit to suit them

22lb/hr I thought. Basically the same as the blue tops, which I was going to get. Look's like it's time to make a trip to Nick-a-Part and grab some.
Don't worry about the tune, when they go in it will have a new cam and different manifold so i'll be getting a custom tune any way.

[stocky]

yeah noones really sure about what size they are, but most agree its 23 or 24. ive also read that theyre the same as group a injectors but could be wrong there.

only bad thing about getting from the wreckers is that you gotta take apart two engines to get them. damn 4 cylinders. oh yeah, a crowbar or something strong comes in handy

CROWBAR!! Don't tell me your one of those guys who only takes a hammer and the biggest screw driver they own there
Surely they arn't that hard to get off the fuel rails.....

nah i had my big toolbox with me. i had trouble getting the fuel rail off one of the cars if i remember correctly. needed to wedge it off with something, hence crowbar. was at it for a while. almost lost a few tools when they dropped down into the engine bay.

and sometimes i will go to the wreckers with just a few screwdrivers if im just having a look. that box gets heavy

0280150706 248 (12lb/ph--12pound) cc @3 bar 15.9ohm magna
0280155777 200 (19lb/ph-- pound)cc @3 bar 12.0ohm commo factory

these so called magna injectors are ok for n/a motor but not turbo or charged they will and do run out of puff
these part numbers are from bosch
i have 3 sets of these magna injectors and have used them the last 12 months but now they not big enough for my custom tune so getting bigger ones

The magna's arn't smaller. Why would be change to a smaller injector.

youve said it yourself. magna is 248cc, stock is 200cc

yer hi.. soo magna injector's are better in a commodore.. y is that.. sorry if i sound like a dumb ass but im no machanic im a panelbeater.. do they make the v6 go harder or what. do you use the magna injectors on a stock v6???
is it well worth the money?

[vpssguy]

are these magna injectors bigger then 5 litre one cause ive been told they are bigger but not sure.cause if they are i want to get some for my 5 litre vp.

no dont put them in a stock car. me and 10000_fists both run superchargers on our cars, and airstrike owns a v8 that is gonna make a fair bit of power.
putting them in a stock car, especially without a tune, will just make your car run rich

pretty sure theyre bigger. same size as group a injectors

[badger__rox]

ohh ok sweet..

[badger__rox]

how much did a supercharger n **** set you back.. ive been told that superchargers arnt any faster off the line only at higher speeds the make a diffference....

i always wanted to wack a supercharged v6 in a 70 model coralla...

they build up boost as rpm increases. with my charger, because the throttle body is after the charger, when the butterfly is closed, all the compressed air gets trapped in the pipe, so when the butterfly is opened again you get instant boost so its quite good off the line

[cracker]

vn-v6-v8 are the same injector
blue tops come from hsv 5.7L engines and some magnas
creams tops come from gorup a's and older magnas
no point in a stock engine good for mild n/as
best bet is the ecotec injecotors in a stock v6 made mine much better
think ill just run a adjustable fuel pressure regualtor with my set up they can be had for about $100 only looking for 6-8psi sinmluar to a crs blower but with less heat hopefully

The cream tops definatly flow a bit more than blue tops, I've proven this to myself last week because I put some blue tops in my car last week and it needed a kinjflow of in the .12 range to run properly with blue tops yet the group A tune (creamtops) uses a kinjflow of .11 which I tried and was so lean on the blue tops I was making about 80 rwkw and surging and pinging . If you want a good injector that is cheap and will swap into your VN without a retune and probably make you a little more power just because it seems to be a more modern injector with a better spray the run the VP/VR injector that is called a 906 I think

I have the 906's in the SS now mate. As for the cream tops making more power what rail pressure did the VN Group A and the VR/S 215's run? Might be were the difference is because I was led to believe they were the same or the blue tops a bit more.

does that mean i need my tune adjusted to .11 instead of .12?

[greenfoam]

I'm talking about V8s stocky.

Airstrike I often wonder if the group A runs a different regulator because the creamtops are designed for a different pressure but yeah you wouldn't think so ? it's a good question to put the to local spare parts man though

[Bz Kn33z]

906s are 23.3lb hour

[AirStrike]

I can do you all one better...............92-94 Magna's use Bosch 775 blue tops
Now just to get them rebuilt.
