New (Or Refurbished) Injectors? 2.7L 3RZ-FE

The pink injectors are far better then the older ones, more holes means a finer spray and better fuel atomization for a more complete burn. I'm not sure why you think they clog but they don't, they are just as reliable as the older ones. Theres a filter in each injector plus you have the fuel filter. Carbon does not build on them because they are always spraying fuel.

 

Good to know... I'll look into the pinky's

 

Anyone try these “18 hole” version from Osidetiger?
I got pinched on some Chinese counterfeits recently on eBay that immediately threw a P0172 rich code and ran terribly.
Need to go with some new injectors for my rebuild.

Man I have some brand new I bought and never got to them before the truck was traded.

 

exact same thing for me as well

 

I’m going to YOLO and throw a set in. I suspect I have ran the Chinese counterfeits for years with my old set.
Will keep everyone posted.

 

I put the Osidetiger 18 hole injectors in. Before & after results seemed to tighten up the short & long term fuel trims. Noticeable idle improvement.
Had a couple days previously put a new Denso front oxygen/ AFR sensor in so not completely apples to apples test.

* note for anyone chasing an acceleration stumble and erratic idle without a CEL check engine light. I had previously bought front & rear combo oxygen sensors from Amazon. The truck drove horrendous with the symptoms listed above. Felt like an EGR stumble from back in the 90s. Finally took to a shop and they unplugged the front 02 sensor and symptoms went away. Went back together with a Denso sensor. Truck purrs like a fat cat now.
New rebuild with LC street pistons, Spool rods, Stg 1 cams, balance shaft delete, +1mm valves & ported head, LC 35lb flywheel & clutch, all reciprocating bottom end balanced to 1 gram, previously goodies reinstalled Thorley Tri-Y header, LC bored throttle body, LC underdrive 3 belt pulley, billet crank gear for the timing chain. Now the Osidetiger 18 hole injectors.
While truck was apart we dumped the Volant dust/hot air intake and plumbed in a stock 3rz air filter box to the elbow in the fender then sealed all the connections so engine is fed air from the snorkel I had previously installed during body work and a paint job. Stock style Bosch paper air filter.
The older I get the less I like cold air intakes and K&N style filters. I want zero chance for dust to enter this engine.
We also installed the Total Chaos lower ball joint conversion and new Moog greasable tie rod ends which were flipped to top mount during the conversion.


For comparison the old worn out 3rz came up our hill @ 25mph and now after engine with 700 miles and mostly broke in come up the hill @ 50mph.
