Twin Turbos

Did Nissan ever come out with a twin turbo, beside the 300's?

there is a Frontier here in jacksonville that is twin turbo from the factory. 1 of 1 custom made by somebody that knows somebody at Nissan

[BeCool]

Yeah right, let me see the pics of it ;)

[CunningLinguist]

ok, my bad. just got clarification that it was made into a twin turbo.

[Mr.K20]

i dont think so.

[edit] RB26DETT

RB26 in an R33 SkylineThe RB26DETT engine is a 2.6L Inline-6 engine manufactured by Nissan, for use primarily in the 1989-2002 Nissan Skyline GT-R. The RB26DETT engine block is made from Cast Iron, and the Cylinder Head is made from Aluminum. The cylinder head contains 24 valves (4 valves per cylinder), and uses a Dual Overhead Camshaft setup (one camshaft for intake valves, and the other for Exhaust valves). The engine also uses a Parallel Twin Turbo system. The Turbo system is arranged so that the front turbo is powered by the front 3 cylinders, and the rear turbo is powered by the rear 3 cylinders. The turbo chargers are of equal size, and are set by the wastegates to limit boost pressure to 14 psi, although the Skyline GT-R has a built in boost restrictor to keep boost under 7 psi.

Most owners that have chosen to modify the engine have been able to produce 600hp without modification to the engine internals (by use of larger turbocharger, and either keeping the stock twin turbo arrangment, or using a single turbocharger). With extreme modification, the RB26 motor is capable of power in excess of 1 megawatt (or over 1,340 hp). [2][3]

There is a common oiling problem with the pre-1992 R32 RB26 motors, as the surface where the crank meets the oil pump was machined too small, eventually leading to oil pump failure at high rpm's. This was fixed for later versions of the RB26.

Originally the R32 GT-R was planned to have a 2.4L RB24DET, and compete in the 4000 cc class (in Group A rules, the displacement is multiplied by 1.7 if the engine is turbocharged). This was when Nismo was going through the process of designing the R32 GT-R to be a Group A race car. But when the engineers added the AWD system, it would make the car heavy and less competitive. Nismo made the decision to make the engine a 2.6L twin turbo, and compete in the 4500 cc class, resulting in the RB26DETT known today.[4]


The RB26DETT was used in the following cars:

Nissan Skyline GT-R R32
Nissan Skyline GT-R R33
Nissan Skyline GT-R R34
Nissan Stagea 260RS
Tommy Kaira ZZ II




[edit] RB26DETT N1
The RB26DETT N1 is a modified version of the RB26DETT engine. Nismo (Nissan Motorsports) found that the standard RB26DETT engine required too much maintenance to use in a Group-A or Group-N race car. As an upgrade, Nismo balanced the crankshaft to a higher specification than stock, as the RB26DETT engine experiences vibrations between 7000 and 8000 rpm. The engine also has improved water channels within the engine block. The top piston rings were also upgraded to 1.2 mm. The N1 engine also received upgraded camshafts, and upgraded turbochargers.

Although all versions of the RB26DETT N1 engine use Garrett T25 turbochargers, the specification of the turbochargers changed through the 3 generations of the RB26DETT N1 engine (R32, R33, and R34). The R32, and R33 versions used Journal Bearing T25 Turbochargers. The R34 RB26DETT N1 engine used Garrett GT25 turbo chargers (which use a Ball Bearing, and has much faster response than a Journal Bearing due to reduced friction).

The biggest difference between the turbochargers used in the N1 engine, and the standard RB26DETT engine, is that the Turbine Wheels in the turbocharger are made from Steel, rather than the Ceramic used for the Standard RB26DETT turbochargers. The Ceramic turbine wheels are found to be very unreliable when used at higher temperatures (such as when the turbochargers are used at a higher boost pressure than stock).


[edit] RB26DETT Z2
This is the engine used in the Nissan Skyline GT-R Z-Tune. It uses the stronger RB26 N-1 block, modified with Nismo parts, bored and stroked to 2.8 L (87.0 x 77.7 mm). The end result was the RB28Z2, which puts out 500 hp (368 kW) and 540 N·m of torque [5].

did you type this up on your own? You have quite the imagination!!! lol ;) I need pics, im a man I do not read much hahahahah

well, i did not write my previous post. i did a little cut and paste action!


P.S. my car is in pieces

What are you reffering to bro?

[CunningLinguist]

i think he's referring to the tow hook in the center of the bumper. it's a show car obviously....not that it won't go fast, but tow hooks are for the real drag racers out there.

[SpeedJunkyz]

You mean someone dumb all that ass in that car and they aren't enjoying? That should be a crime, I would be screaming slideways!!!


SJ

[CunningLinguist]

i feel the same way

[SpeedJunkyz]

im going to track my evo......circuit that is......that'll be fun!!!

I thought about twin turboing it too.....haha than I called myself a ricer and called it a day!!

SJIt's either a real waste of good machinery or a case of too much money. :(

i think hes referring to the rb26dett in the 350z, they are around the same hp stock for stock i think so there was probably nnot to much of a gain from it.

and as for twin turboing the evo
can you even tt a 4 cylinder engine? i always though you couldnt but correct me if im wrong.

Yes it is possible to twin turbo a four cylinder!!! We have a local guy with a TT 92-95 civic coupe. It never comes out though cause its mostly show and its always broke down!!!

Twin turbos rock

[Grrarr]

If you've got patience, time, and a good amount of experience. . . you can sure as hell run a nice twin turbo setup on a four banger, no prob!

All you need is to run a sequential setup, (That means one turbo will kick in at one RPM, and the other will kick in at another RPM), and make sure they are smaller turbos. No need for a bigass ridiculous turbo setup.
After you've got your setup, you need to get someone to tune it, screw around with the fuel map, ratios, etc., and you're good as gold. Make sure also that you're not running a big horsepower setup, otherwise you might as well just run a single turbo.

If you're running a twin turbo setup you're looking for a wider boost range with good response.

My apologies if I've said too much. . . I'm just a fan of twin turbos. Big fan.:Gunner:
