2006 Turbo Puddle Jumper

When they said they have an 1800 HP 3rz....

It got me excited... Probably the main reason I went with LC !

 

Easier swap than an LS!

 

Blows my mind how fast an efr turbo spools up.

 

This

 

But that cost. I'm thinking a gtx3071 or the efr 7064 for my truck.

 

Im going with the twin scroll too, for better mid range boost response. I was gonna go with the 7064 but im shooting for much higher HP numbers now. I could probably go twin GTX for the price of one EFR haha

 

My BW 9180, with a 1.04 A/R T4 inlet (despite twin scroll setup), spool through the boost threshold sooner than the SMALLER Precision Turbo 6266. Which is journal bearing, .86 A/R T4 tangential inlet. By a measure of 500-800 RPMs. 1000hp turbo versus a 700

 

excuse me if this is a dumb question but if you put a turbo in and are essentially getting more HP to the wheels does this help with being under geared? i see a lot of built up rigs have 410s and thats what our trucks come with stock. instead of spending money on gears i think a turbo would be more fun.

 

It does but you should never skimp on proper gears for your tire size.

 

Most tacoma guys are driving a V6 and if i remember correctly, the V6 uses a 3.73 and benefit from moving to a 4.11 setup to increase torque. That would lend us to go up to a 4.30ish ratio to get the truck back in the stock powerband.

Now, I want to be the voice of reason for you. The price of the gears and installation of the gears(if you don't install them yourself) will cost just as much as a single, new, turbocharger. After the turbo, you need exhaust manifold, injectors, blow off valve, wastegate, 1:1 rising rate fuel pressure regulator and much more.

I am well into $10,000 worth of parts specific to the turbo build. That does include a $2,000 spare motor too though.

I would say regear to something in the 4.30s, but not further than 4.50s. It will be worth it far sooner than a turbo kit would.

Good luck with your decision, and feel free to ask anything else you may think of

 

thanks for the response @MrCrowntown

 

Holy crap man i had no idea u had that much cash dropped in ur setup. Im sitting at just under $3500 on mine for the 4.0 but i did everything myself so i have $0 in labor. Ur also gonna be able to run like 3x the boost i am i guess since ur on a load of forged internals. But i would think stock internals would handle enough to well surpass the next step in a regear for not much more than a regear front and rear if you can fab everything yourself. Heck on a 4cyl you could mostly get a manifold for about the same or less than i have on headers and all my pipe for crossover and up pipe. Then all u would have to worry with is the down pipe

 

I very much could have went cheaper haha

I decided very quickly, as I discovered the true strength potential of the block, that I could push it to the moon with no worries. So I invested into the idea of 1000hp+ very quickly. I grabbed a couple spare heads that I have been playing around with porting and polishing to get me some sweet CFMs too. Those and the tooling to achieve what I want are included in the total as well.

I am sure the total will go over 20k once I get into axle upgrade and trans bulletproofing. But for the last ten years that I have had this truck for, I have dreamed of doing exactly this. Now I can afford it, and have gotten to a place mechanically and mentally that I'm ready for some sweet, sweet boost!



Edit: I will be doing most of the labor as well, but I cannot pass up an opportunity to be part of research and development for LCEngineering either..

 

You're welcome bud, glad to help anyone I can!

 

Gears are worth it even with boost. If you add weight and large tires gears help a lot. Helps tighten your gear ratio between shifts. Plus you'll never be under 3k rpms.

 

Thats an excellent point that I had honestly not considered yet. Since the redline will probably be extended up towords 9-10k a higher ratio would be beneficial

 

I already want a higher rpm. 7k red line would be sweet.

 

Snag some cams! haha
