1997 Tacoma SX v6 5sp TVS1320 supercharged 300 HP! Haltech ECU, Reg Cab 750,000 Build

Hey john I like how you constantly keep updating your truck to the latest technology.

 

me want

 

Got the dreaded P0171 code yesterday And have been dealing with fuel trim levels that were extremely high for two weeks.
So after getting all new vacuum lines and having the dealership try and find the issue with no answers I
decided it was time for a new fuel pump. The last pump failed at 300k and I’m at 605k now.
AFR numbers were getting leaner at full acceleration 13.5-14.5 and higher Long term trims +25 which indicates the engine is running lean and the ECU is trying to compensate.
Having a scanguage to monitor your fuel trims is a great tool to have.
One word of caution if you remove the bed to replace the fuel pump is to be careful with putting any weight on the rear quarter panels as there is no body support on these sections and the can buckle easily. Make sure the weight is supported from the center of the bed area.
So a P0171 code can be a failing fuel pump.
Took about 3-4 hours to do because the high pressure line didn’t want to come off.
Finally got one side off.
The bed is definitely in the 250 pound range and the drivers side has to be raised very high to get
it over the filler tubes and installing the bed has to thread the filler tubes back in that specific area.

Looks like the life on a DENSO fuel pump is 300k.

 

So I discovered a cool option for my supercharger a few weeks ago.
The original 1st supercharger came with a nose support bracket that also had the idler pulley as part of it. The bracket supports the front end of the supercharger as it has 80 pounds of belt tension on it
and has 5 small bolts that hold the supercharger to the intake.

The idler pulley was updated and replaced with a dynamic tensioner and the nose bracket was discontinued. I found out that you can take this original bracket and cut the one side of it off
and it then becomes a nose bracket to support the supercharger with the dynamic tensioner at the same time.

So I found a used bracket from another member, had it cut and the top and bottom ends rounded and sand blasted.
Some 3 layers of paint and it fits perfectly.
Looks like an OEM part now

 

have you tried using the newer dynamic tensioner?

 

quick question, do you get a low rumble from low rpm and climbing up to a high rpm in a lower gear?

 

I’ve had the newer style tensioner on for years.
This is just the support bracket that I cut out from the old type tensioner to give the supercharger some nose support. It’s working great.

 

Nope, that’s sounds like your talking about pinging?

 

The truck made it to the fast lane.

Here is a good video of the truck.

I just watched it and had to come here and make sure it was the same truck haha. Congrats my friend that’s pretty cool!

 

Congrats John! Awesome video and once again awesome truck!!

 

Saw your truck on flt. Looking so good.

 

I just came across your video on YT. It was on my recommended videos. That's pretty awesome man! They should have talked about the work you put into that scoop!

 

Doug Thorley headers now installed,

Definitely feeling the smoother little added power now.

 

Were they a bitch to install?

 

Absolutely!!!!
I was going to do these but because the EGR pipe was not correct and needed to be custom made and that there was a chance the bottom collector might not fit perfectly and need welding I had a shop do it,
Plus the bung for the AFR

They told me THEY WILL NEVER DO ONE again

Said the instructions were worthless, Kit was missing hardware,
Bolts were missing, Exhaust manifold bolts were a job just to remove and get loose
without breaking, said it told easy 10 hours to do.

I’ve always wanted headers and this was one of my items on my list, but because of the expensive has always been the item on my list.

 

Damn that’s pretty wild man! When a shop is saying all that, I can’t image how a shade tree home mechanic would feel. Nice to finally have them in I bet, though. I’ve read they help the motor breath much easier with the S/C sucking so much air.

 

It absolutely does the higher the rpms go, will Dyno it next week to see the difference .

It’s doable for someone if you have a welder on hand and the extra time

 

I did my jba an got lucky didn’t break a bolt or snap a stud off in the heads, only had to have y pipe extended an have a flange to bolt up to the can

 

Well after all these years I finally found a headlight solution for the 7 x 6 my headlights.
The projector headlight mini h1 7.0.

The stock headlights suck no way to argue with that even the upgrade options are not that great.

Just finished doing this upgrade, 220.00 for the projectors and 75.00 for the glass and metal buckets.

A world of difference,
The high beam is crazy strong and shoots super high
