Does anyone have any suggestions on where a suitable location is to tap the high pressure gallery to supply oil to the turbo without issues of potentially dropping pressure to an engine bearing or other pressure dependent component?

I installed a turbo on my first tundra ('04) and was able to tee from the oil pressure sensor without issues. I assume this will be similar to the 5.7 but honestly I havent even looked under the new truck to know if this is possible. Is there an easier/ better location I dont know about?

*I am using flow attenuators into the bearing cartridge.
Turbo is: Precision Turbo 6057 Billet BB.

Thanks

I'm interested in seeing the total cost, install, and results of this.... I'll be waiting! :fishing:

Any technical questions of this nature could probably be given to Brian over at Jowett Engineering on here. Give him a try, good luck!

I would tie the oil feed into the oil filter housing at the pressure sensor port. The oil pump on the 5.7 should be plenty capable of supplying enough extra volume for that type of turbo.

What size restriction orifice are you using for that turbo?

How are you going to tune for that setup?

I'm also in PDX - I'd love to see your project and chat a little :D

I make my own restrictors depending on the turbo-oil pressure of the particular engine. My race motors make well into 125 psi and use a .030-.035 for the bearing turbos and .055-.060 for the journal turbos.

For the 5.7 I will use .040.


For tuning I use Microtech. Depending on the manifold layout I will use 8 secondary (batch fired) injectors or 4 low impedance. The stock ECU will control the factory FI until the MAP sees pressure and tuning tuning turns on the secondaries.

I am only looking for 550 HP and not wanting to pull the heads. I feel 550 is enough to take care of most anyone with the TRD supercharger without lowering the CR, increasing the valve spring rate, and replacing rods or pistons....this is after all....my work truck.

I am always willing to talk about projects......once I get further (I am still in design stages) I am great with getting together and showing the progress.


*also.....
I keep cost down by using the OEM headers by using a U bend and pipe at the junction to redirect the exhaust back under the hood and support the turbo frame with brackets (as apposed to mounting the turbo to rigid headers). The exhaust is then redirected back to the factory exhaust. THis is also to prevent issues with OEM o2, allows me to remove the turbo (while only replacing a mid pipe) and lets the exhaust exit the rear of the vehicle (I have been known to use a dump pipe under the vehicle).

^^^ Damn yo! This guy might actually know what he's talking about!? :) Hey HotNuts.... what kind of cost (ball park) are you thinking for this? Also, is this something I can do myself, especially the tuning portion (with only basic mechanic knowledge) ??? I should have some extra play $$$ in summer, and I've always liked turbo better than a belt-driven blower, especially if it's not too expensive. You've got me very interested!

Drop me a note if you are interested in additional tuning ideas.
Will do, and even I am thinking because of my smallish HP goals I would be better off just using a rising rate FMU, larger injectors or even just increasing the FP if the stock ECU is mappable (or if a piggy is available).




You can see I have f-ing issues~....


LOL

Any thought of twin charging? :behindsofa:

It is.
Didnt recognize the dash as on 06 Tundra??
LOL
Just got a new push vehicle (07 tundra *more on that soon).

This vid is from 08. Last year with the turbo motor I spun the car over 200mph on the backup (they take the average of 2 runs after you qualify but was happy to know the car would easily run 225+{geared @ 11K rpm in 6th} (on a 205mph record).

Here is a dyno vid of the car with the turbo motor:
YouTube - JHotnuts's Channel

We tuned to 590 hp (and could of gone well past) but de-tuned the engine to 440 HP for the runs....we simply didnt need it...but it was nice to know it was there!

Any thought of twin charging?
I just looked over the bay, really tight on each side to the fender well and steering box.

Seems to be much easier to have 1 up and 1 down as apposed to 2 up and 2 down and almost no clearance on the drivers side.
I am open to suggestions if there is someone who makes headers for this or any thoughts on how to do it.

I was thinking more along the lines of running a turbo and a supercharger. I have a fellow Camry forum member that did this with his. He runs 560 fwhp and 480 lb feet @ 22 psi.

I think it is appropriate to say that I am aroused both mentally and physically due to this thread. Will keep a close watch on your progress there Johnny!
