The overall length and width of the 5345

ikh22 are the same as the 5346

$12 ikh24 denso 5346 spark plug

ikh24 im running in my truck, so they will fit 100%. However if your truck is stock, the

$48 Denso SK20HR11 ---- IRIDIUM PLATINUM power pack Spark Plugs -- # 3421 ----- 6 PCS NEW

Denso SK20HR11 are the better choice imo. The 5345 are one step colder so im not sure what effects that would have running it with a naturally aspirated setup. Typically you go with colder plugs in boosted applications. Now that I think of it I believe @dirtdigginjoe is running the 5345's but his truck is turbocharged

 

Yeah she’s stock for the most part, starting to build her up little by little & hoping to add a header soon but there’s still some time before I go to boosted/SC so I guess I’ll stick with the

SK20HR11 for now.
Thanks for your input!

 

Tinkered a little bit with the tune for the truck tonight. Started out with the file URD provides for their blower and then I added some fuel with the 5th injector. Before doing this I was having an issue where the truck would go lean in 3rd gear WOT at around 3500rpms and up. AFRs were in the high 13s under about 5psi. I wanted to see closer to the 11.5:1 range so I did a couple revisions and now AFRs are looking a little better. I think I remember @Torspd saying you tried to help your friend add some fuel to his tune a while back. Do you remember if it was also on the top end? The rest of the tune seems pretty good, it was only 3rd gear after going into open loop that it would act up

 

Prior to the open loop transition, around that area. Then something around or over 4500+. His was also pushing around 12 psi. We upgraded the 5th to an ~800ccm injector to help.

 

Thanks for the info! Yeah mine only makes about 8lbs at max boost. I put the stage 1 85mm pulley on it yesterday though after i noticed the fueling issue. it was making around 10lbs on the 80mm at 2k feet elevation

That's a good idea upgrading the 5th. Is this the one yall used? I am going to keep this in mind for fueling later on down the road

 

I believe that is the one he purchased.

 

As a follow up to this, I have done a couple revisions to my tune over the past couple of days. The only thing I changed from the stock URD tune was on the 5th injector. All the primary injector stuff and timing has been left alone.

I was unhappy with the AFRs that the truck was having on the stock URD tune under low-mid boost in high load situations. I've got it pretty good now where in the 1-3lb range AFR is in the mid 12s and once it goes over 4.5lbs of boost it drops down into the 10.5 range. The whole reason I went after this was to try to get a good safe tune for my daily driver. I know every truck will be a little different, but figured it might be useful to someone, so I wanted to share.

For reference, I am running the following:
- URD SC w/ stage one 85mm pulley
- LCE header
- URD power pipe
- Stock catback
- Stock toyota air filter

 

Well done, and super handy having posted that up.

 

I am using the

$9 IKH22 Iridium Power Spark Plug, (Pack of 1)

IKH22's with no issues. Sorry for the delay, I've been busy with life lol.
I don't see a reason to go with the IKH22's if you're staying N/A. The truck doesn't make enough pressure at the dome to warrant it when N/A.

 

Does anyone know how many CCs the stock injectors are rated for? Trying to figure out the biggest Injector i can run with the MAPECU3. It says no bigger than double the stock size

 

When I was talking to FiveOMotorsport, the stockers were roughly 285cc if I remember correctly.

 

I want to say the max Gadget had mentioned was around 550ccm. That's from a memory when he tuned my truck with them.

 

Thanks gents!

 

The FSM has a range for the injector flow. I believe the middle of the range is 315 cc. @05Taco4x4 has posted it before if I'm remembering correctly.

 

I did in the Turbo BS thread, but can’t recall. It was something like that

 

Installed this on the truck last night. DNA motoring piping and a borla offset/offset 2.5" muffler.


It is a little louder than i was hoping for, so i am going to cut the front pipe and install this tonight. Hopefully it will mellow things out a little.

 

Has anybody ever flow tested the 2TR stock injectors to see what they flow? There are so many companies making them, it could be why Toyota lists such a wide range of flow in the FSM.

 

Took a little sound clip of the new exhaust setup. It has gotten a little louder since install, but not very much. It's pretty quiet while cruising, and doesnt really get loud until you mash the skinny pedal. I am pretty happy with the way it sounds for a 4 banger

My setup for reference:
URD S/C w/ stage 1 pulley
URD catless midpipe
Two borla 2.5" mufflers
LCE header

Sounds good. I like it. Makes me want to get back under my friend's and add a little personal modification of mine.

Yours says Borla mufflers. You have two mufflers?

 

Thanks man, yes i am running two borlas. A 400496 & 400490. With only one and it being catless it was way too loud and obnoxious for my daily driver. Much better with an extra muffler. I might add another at some point, but it would need to be in the midpipe.

Here's a pic after install
