TB42e standard injectors

[Irish]

Hi guys, anyone know what the flow rate/size is on the standard injectors? Can't seem to find any proper info on em.

[billyj]

from memory it was 160 or 170cc

[Irish]

Thanks for the reply mate, that seems a bit small though?

[billyj]

sorry mate that was supposed to read 260cc, still a small injector, wont even keep up to 4psi of boost

From what I have been told

2.60cc and size is 11mm standard for the TB42E, You can not buy these brand new, can but buy reconditioned or recondition your own

370cc for Turbo

Why do you ask?

Their is a mob in Melbourne that does new fuel rail and takes 14mm injectors for the TB42E, I'll send you a link later when I get the info of my old man.

4bfab redrilled my injector rail to 14mm when i went turbo, now running 660cc injectors

Might be the same mob, waiting for an email from my old man

I'll be looking at turboing the Maverick at some point now that it's got efi gear running the fuel management.

Was looking into Nistune + bigger injectors + turbo gear to get a rough idea of pricing. Have twin pot brakes and slotted discs to install, plus I need to figure out how much it'll cost for VASS signoff for the mods too.

im about 5k in with axt manifold and turbo, no intercooler, 3" exhaust, walbro 255 pump, 660cc intectors, nistune board and tuned. as for power nfi atm it really woke up when i added the 3" exhaust and fixed the wastegate recently so really needs a retune.

i may be stripping the tb42e and turbo gear out in 6 months or so to fit a 355 stroker instead not sure yet, only because i have a fresh 355 sitting in the shed

I've already got a manifold so thats one less thing to worry about. Have a started a shopping list for the other bits and pieces and have em on my regular ebay search list. I would have gone down the road of diesel or V8, but I've got two TB42's sitting there(one is in the car). Figure I'll run one til it dies, then pop the other one in. I'm not chasing mad horsepower or anything, just enough to perk the old girl up a bit.

Have been trying to educate myself on forced induction too, currently reading "real world high performance turbocharger systems"", it's a little more indepth than I think I need to go, but good to understand the how and why.

put it this way on 4psi with a shit 2.5 exhaust with restrictive mufflers and a wastegate that was blowing open it made a lazy 100kw at the wheels, which was a great improvement over stock, the exhaust helped a bit more and fixing the wastegates preload helped alot getting full boost by 1200 rpm pulls better than a diesel down low but have some major boost creep which needs an external wastegate to get under control. im still half considering fitting an external wastegate, intercooler and retuning to run on 10-12psi but in reality its only gonna make about 170-180kw when the stroker makes about 220-230kw with great bottom end torque

also be very wary of ebay manifolds as they have a bad rep for warping and cracking

Off topic Irish but when you quoted me in your post were you on a mobile using tapa talk?

[Irish]

Thanks for the info guys, much appreciated :-)

Yeah, haveheard the same about the ebay manifolds, will keep an eye on it, and will probably fab one up if it looks like it's gonna fall apart.

Niss, no mate, I'm just on the regular forum page, using chrome on my HTC M8.

That efi hardware place is real near where I collect my parts for work, might stick my head around the door next week.

Let us know how you go with them if you do

[Irish]

Will do mate.
