truck header installation


Early Riser

Question

Can anyone recommend a shop that could possibly do a good and resonable job of installing some JBA headers on a 2002 Toyota Tundra V8?

That is going to be a tough one.. that will require drilling into the headers for the installation of Oxygen sensors, etc.. unless its already drilled out.

The reason why its going to be tough.. is shops are not going to want to warranty their work on aftermarket parts.

You might have an easier time getting it done as long as you have the complete exaust specified for your truck.. not just the actual headers.

Look in the phone book for Hovde automotive in minneapolis.. he has a small place there and has always done good work for us when we needed him.. including jumping a few hurdles.. no promises, but he might do it for you.

We also have a life long family friend that is ASE certified and works on city vehicles every day that might take this job on if/when he has the time. email me if you want more info.

Fisher Dave, Thanks for the information. The headers I am buying are made for the Tundra and bolt on to the original exhaust. By keeping the original exhaust, low end torque is preserved, and mid range torque (2400 to 3400 rpm) will be enhanced by the JBA headers according to the available dyno data. The other modification for low end torque that people have used with the Tundra is to add a Gibson mufler to the stock exhaust after the truck's computer has adjusted to the new headers. The Gibson sportsman muffler actually is a very quiet muffler which is good for me because I don't want a lot noise.

A good website for information on these trucks is tundrasolutions. They have a group buy on the JBA headers right now until the 15th. A very good price for both the titanium coated and the stainless.

The Tundra does have very good performance already, but I am looking to add some modifications. By the way ts members with these mods report about a 20-30 mile increase per tank of gas with the headers. That is if the foot isn't too heavy!

I will give Hovde a call and may indeed call on your friend. I will let you know if I need his name. Thanks again for your help.

I've never heard a vehicle yet that had headers and wasn't loud...

most people who put headers on are running strait pipes or some type of performance exaust to make it the most obvnoxious it could possibly be... they can be quiet if the proper exaust is installed, with minimal amount of backpressure to reduce the performance. A good example of performance would be the standard older 350 chevy motor.. a header application boosted the horsepower by about 30 on the average... that was 10%-20% depending on the stock motor(year).

I like to have a little extra power.. but I dont like setting off every car alarm in the neighborhood starting my truck.. or scaring every deer for a mile in hunting season either.. My truck has 3" exaust on it and it is not loud.. or wasnt until I just blew out my muffler.

i must say that you can slap a pair of headers on anything over the stock manifolds and gain power. but, you are only going to gain as much as the stock heads flow.

lots of people get all excited when they read something that says 30 horse gain right out of the box. ha i get a laugh!!!! because they neglect to read the fine print that states " up to a 30 % gain with such and such parts"

better flowing heads, upgraded cam, rockers, springs, performance exhaust. now days you need to upgrade the maf, have a custom dyno tune, play with injector size, fuel pressure, maybe slap on a super charger. keep it stgreetable and still get good gas milage.

have fun, becuase it takes lots of money to build horsepower.

jim

i better go back to the tcstang forums.

jimh I hear you on this one. I have really looked into this topic. The modifications I have been researching, and now gradually moving forward on are proven to be reliable for the Tundra. A lot of people have tried different things including catbacks, duals, flowmasters, y pipes, chips, airboxes, etc. Many of these things just make noise or do nothing at all. The combination of modifications proven on the dynojet and real word applications for torque(not just HP), for this particular truck, are the JBA headers, stock exhuast, stock airbox, and the mufler (Gibson for quiet). This truck's computer is able to calculate the proper air/fuel mixture for optimal power and milage.

This topic can get into some very interesting discussions, which are gone over at length on the tundrasolutions website in both the engine performance and towing sections. Nevertheless, I really do appreciate all the suggestions and insights offered here! I want a local shop rather than taking the truck to the dealership who would charge four times as much as an independent guy. It is also interesting to note that Toyota makes a header system for the Tundra that is very expensive and no distinct advantage over the JBAs. Thanks again.

HiTech Motorsport in Ramsey will put them headers in for you.

Also, they will Dyno Tune your truck to maximize its potential after installing the heads. (this costs extra)

A set of good headers and a dyno tune will make approx. 22-30 RW HP and 25-35 Ft Lb of torque.

I added a high capicity cold air intake and a Hypertech chip to my 2005 Silverado recently.

The air intake produces a throaty sound, added some low end power, and increased my fuel milage.

The hypertech chip removed torque limiting, increased the shift firmness, increased the rpm of WOT shift points, changed the high end speed limiter, increased low and high end power, and has raised my acceleration in 95 degree humidity to better then what it was in 40 degree crisp air.

Worth noting, I used the lowest performance increase setting available on the programmer.

It woke this motor up quite a bit.

Next is some headers and dual exhaust and I'm done with it.

Ohhh. Forgot...

Jim said SUPERCHARGER.

Do a Supercharger (only $5,000), headers, dual exhaust, and a dyno tune after all is installed and you will increase your HP at the wheels by at LEAST 100 HP!

Yee Haa!!!!!!!!! wish I had the $7,260 to do all that right now!

      I have a Weboost cellular amplifier at Wakemup Bay. It increases the signal from 1 bar or less to 3-4 bars BUT there is more to the story than bars. For data (like streaming video) I get faster data speeds WITHOUT using my booster. The reason as I understand it is that cellular data transmits and receives on multiple channels simultaneously (its called Multi-In-Multi-Out or MIMO.) Most boosters only amplify a single channel at a time. While the phone shows a good signal from the booster it can actually reduce the data speeds that are available with MIMO transmissions. A booster can improve your voice communications while diminishing your data speeds. You might want to look at the Mobile Internet Resource Center on YouTube for a better explanation.

      So sorry, wish I could boat over to help. I think we will wait an extra week to head north.  Prayers for a good resolution.

      Good morning Mtnman. Yes, the whole rainy lake watershed is under a flood warning. Water is as high as it was back in 2014. Forecast is that is should peak around May 20. All the ice went out last week with all the wind and rain we had. My dock didn’t make it though. Ice blew in and lift the whole thing, crib and all. Mother Nature…adds another project once the water is warm enough to work in. This week looks a little drier…I hope! Safe travels when you do head North.

      The water was over 22 at the very south end of Mud and the overflow pond. I took that route to get to the cabin, I just moved the signs and drove through, saw a couple carp sunbathing on the warm road. 😂
