turbo or twin turbo titan

big8514 · 08-22-2007, 03:40 PM

Im planning on doing a custom turbo setup on my 2004 nissan titan king cab. as of right now if i do a single turbo its going to go right where the air box is but if i do a twin turbo setup one will go where the airbox is and the other one will go in place of the battery which will need to be relocated. i was just wondering if anyone else would be interested in a setup like either of those. just another choice instead of the stillen supercharger.

I'm not interested in turbo charging my titan but I'm sure a lot of titan owners would be interested. Turbo charging would be the best route and I would love to see some turbo charged titans running around.

seems a little pricy how much would it be?

not sure how many steps in regards to ECU have been made, but i remember that the biggest obstacle in turbocharging our Titans is the ECU. But if memory serves me right, UpRev **MAY** have a solution to our problems....

I would like a single turbo. I would call UpRev and see if they can tune for it before you build it.

For V block engines, I would do the twin set-up. Secondly, putting the turbo(s) in the area that you stated is not a good idea. They should be tucked away underneath behind the motor mounts to keep piping to a minimum, makes for better response and power and keeps engine / engine bay temps down.

I'll agree with Z Hauler here. The more piping between the engine's exhaust and the turbo(s), the less efficient they will be. It would be a tidy arrangement to put two where you're thinking of though, and if you can get a decent tune, the difference in location of the turbos might not be too terribly bad compared to the overall increase. It sure would be fun to see it done!

Unless the Titans started growing incredibly tall engine mounts or very deep oil pans that probably won't be the best location. On the right track as far as piping for the hotside of the turbo but turbos need to be appreciably higher than the oil pan so that return oil drains properly.

As far as single or twins go...just go with a single. Twin's are good for show but you will make more than enough power with a properly sized single turbo, have a much easier time with tuning (a big plus given how little support there is in that respect), have virtually no lag, have cooler engine bay temps, spend less money, etc, etc...

I have seen a few cars with the turbo mounted at the end before the exhaust, Just stating what i have seen dont know that much about turbos or if this will even work on a Titanhttp://www.supermotors.net/vehicles/...s/sts-a1-1.php

1) Twin set-ups are not just for show. I don't know what magazine you read that out of, but that information is wrong.

2) Turbos DO NOT need to be any higher than the oil pan for any reason. The oil system is pressurized therefore it doesn't matter if the return line goes up, down, or twirl around like a crazy straw. It doesn't matter the direction of the return just as long as it isn't too long and doesn't restrict flow.

True, you can make good power with a single set-up, but as far as efficiency, and performance goes, twin set-ups are superior to single set-ups on a V block engine.

1. Only way a turbo can be lower then the oil pan is if you have a pump which pumps oil from the turbo back to the engine. The oil will not travel back up the line to the oil pan by the engine's pump alone. Eventually it will puddle up, may leak and/or blow out the seals on either the turbine or compressor side if not both. This is turbo kit design 101.

2. Putting a single turbo where the air box is will be fine. Don't take my word for it, just go over to LS1tech.com and look at all the turbo kits that were/have been made for the Fbodies. Some relocate the battery to the back and place the turbo there. Some put the turbo between the crank pulley and the radiator. Some, like mine, relocated the alternator to the driver's side(think LS1/LS6 vettes) and place the turbo where the alternator was. Heck, look at the STS kits, the turbo takes place of the muffler but its also designed to run back there with smaller exhaust housing and some guys have coated/wrapped their exhaust pipes/headers. Think they don't work, please go to LS1tech and lookup Zombie and a few others like him. He runs 10s @130+ in Las Vegas in the summer time with a home-made rearmount kit. I've not only seen his car run, I rode in it and let me tell you, for a street car, its bloody damn fast.

Honestly, turboin' your Titan would kickass! One word of advice, no matter how many times you run the numbers of how much it will "cost", add at least another 30% on top of that for things you go "crap, I need this/that/other thing". It will save you a lot stress and frustration. This is coming from someone who has been around Forced Induction since 2001, small time here..

I would love to turbo my Titan but I have other responsibilities to take care of first before I even think about it. That and my wife would probably shoot me if I made my truck into toy #2.

I would advise anyone who wants to get into turbocharging to pick up "Turbochargers" by Hugh MacInnes. It's a good read and very helpful. Good luck and I'll keep looking for your buildup thread.

The placement of the turbos that I am leaning towards would be in the stock cat locations. They would be more level to, not below the pan. Some 300ZX twin turbo is set ups are this very way. Never have I heard of any oil drain issues or problems caused by oil backup.

you would be a god...

Ain't that the truth.....

As far as twin vs. single....it depends on what you want your end result to be. You can get two smaller twins for faster spool time and AWESOME power, or go single BIG turbo. Spool time is slow (turbo lag, anyone??) but the power possibilities are endless.

I know a shop here in San Diego that has a Supra with a turbo sooooo big, they need a 300 hp shot of N2O just to get it to spool. But, this Supra has just shy of 1400hp.

And, as dark blue said, STS kits do well. I knew a guy who had (sold it) a 2002 Camaro with a big *** STS kit. The turbo was mounted way in the back. The air filter was located where you would think an exhaust would go. That car was simply amazing. Fast as all hell. I don't know the exact ##'s, but it was fast.

As long as the oil can drain back into the pain above the oil fluid line, you're fine. Maybe it was me, in your last post, it sounded like the turbo(s) were going to be below that line.
