Hallo Henning,

werde wohl mal DAS HIER :
http://www.bankspower.com/galesinsidern ... into-Jeeps
an meinen TJ schrauben (lassen?) :twisted:
Ist bald zu haben ... fuer weniger als die ueblichen USD 4000 ... und ziemlich komplett.

Gut zu wissen, dass es hier guten Turbo support gibt ! 8-)

Chafik ich hab schon 2 V6 Turbos hinter mir...damit stehst du immer mit einem Bein im Grab! Mach es nur, wenn du bereit bist deinen TJ zu begraben, im Falle eines Misserfolgs!

Frag mal Henning ob er einen Turbo Umbau kennt den er für die Wüste empfehlen würde! Würde mich wundern!

[quote=".... Frag mal Henning ob er einen Turbo Umbau kennt den er für die Wüste empfehlen würde! Würde mich wundern![/quote]


Grundsätzlich würde ich nie einen Turboumbau empfehlen, egal ob Strasse oder Gelände.
Gerade im Gelände ist Leistung/Drehmoment im unteren Drehzahlband gefordert , ein Turbolader erhöht zwar Leistung und Drehmoment aber meist nur im oberen Drehzahlband ( sicherlich lässt sich auch ein kleiner Turbolader dazu bewegen auch untenrum Leistung zu bringen. Allerdings steht der Aufwand ( und die mit einhergehenden Probleme ) in keinem Verhältnis.

Wenn ein Auto ab Werk mit einem Turbolader ausgerüstet ist sieht die Welt anders aus. Der Motor ist konzeptionell für den Turbobetrieb vorbereitet ( niedrige Verdichtung, Luftführung, Ladeluftkühler,usw. ). An einem solchen Wagen lässt sich der serienmäßige Turbolader immer verbessern ( Grösseres Verdichterrad, Back-cut am Turbinenrad um den Abgas-Gegendruck zu verringern, und um die größere Luftmenge schneller abzutransportieren, Verbesserung des Ansprechverhaltens, Verdichterräder beschichten, usw...).

Auch wenn ich quasi an der Quelle sitze wäre eine Turboumrüstung nie eine Option für meinen JK, wenn dann V8.

Gruss

Re: Turbocharger

ok ...

why do you think I have posted in response to the OP? ... to hear his opinion. :mrgreen:
For sure I will have to meet Henning ... will be a pleasure!

Actually Tobias (Cybershot) is the one who after a long absence of engine mod courage in the club has reignited something ...
Chuck and Dinostroker aka Cheromaniac aka Dr. Dino are probably the initiators of this something :twisted:

Regarding engine death because of Turbo:
Well ... the 4.0 I6L is unkaputtbar in STOCK form ... 8.5:1 CR ... piston rods and crank good for 400 hp ... meanwhile strong head (2001-2006) ... otherwise you could not use it as a good base for strokers (and some of them ARE extreme).
(Only unknown parameters to me : the stock pistons themselves and heat dissipation capacity)
I know it is not a rpm ricer engine and flat tappets and push rods are not really meant for beating ... BUT
The stock cam is mild and the stock lifters are quite good for more than 400k kilometers if you keep the rpm powerband below 5200
So my thinking: if you can stress a stroker (which is basically the same engine but with more displacement) with 270-300 HP and be fine for a very long time ... then why not with a small turbo and additional 50-60 hp (I do not believe the 45% claim either) to the stock 180 hp ... if the kit is right.
I am not going for MAX turbo performance and turbo tuning ...

What I dislike about the banks kit:
- no intercooler coming with the kit !?
- underhood temps will be high ( with all turbos in general)
- inegrated wastegate and bypass is not necessarily an advantage
what I like about the banks kit:
- small turbo ... good for low rpms ... maybe not enough for high rpms (but eventually not needed)
- otherwise complete kit with piping, injectors, brackets and pcm tune.
- obviously not aggressive ... which means less load/stress.
- high probability that everything is matching each other
Btw.: most strokers do not use forged pistons, but the same material as the stock pistons and run ~260 hp ... only the high end ones use the forged stuff (for pressures far beyond this kit)

What is completely unknown to me with the banks kit:
- oil cooled turbo ... good enough in this application?
- HOW MUCH more underhood temp ... but you can do s.th. about that.
- tune and injectors and stock cam, pistons really matching?
- quality of the blower itself ...?
(- eventually a hesco aluminium head (better heat dissipation, less ping) with increased chamber volume (lower CR) and steel valves (to avoid burnt valves?) needed? but then the total costs are for sure beyond reasonable)

What I would NOT do for sure is stroke AAND turbo the 4.0 I6L and exceed hp far beyond 300 ... although some have done that successfully, but not in the UAE and with lots of additional upgrades to the whole drivetrain :lol:

I will wait for the first reviews anyway and continue listening to you guys ... before DECIDING ;)
between Chrysler magnum 5.9 (same block) V8 and 46RLE tranny out of a older Durango ( quite plug and play btw... :twisted: :twisted: :twisted: ) and this.
A 2006 4.0 I6L stroker is not as economic as for older models (You NEED a 2006 block because of OPDA, CPS etc etc ) ... and still quite risky!
(now I have outed myself 8-) )

Re: Turbocharger

The size of the turbocharger should fit somehow to the displacment of the engine.

If you install a turbocharger which is too small for your engine you will earn a lot of negative results. I understand that you like to fit a small turbocharger which supports and increase your low rev power and torque, but what happens in the higher rpm? the turbo ist still connected. now you are pressing exhaust gases from a 4.0L engine thru a tiny turbocharger. The small turbine wheel is forced to spinn faster (overheating, sometimes shaft sheer-off). If the turbo is a ball-bearing he will die if you exceed 130.000rpm.
Your turbo must fit to the size of your engine, even if you just need it in low rev.
Your 4,0L engine will push at 5.000rpm rughly 10.000L/min gases thru your turbo, this can not be handled from a small turbo.

From the picture of the Banks website we believe that is a GT28 Turbo, this turbo is a ball bearing, but watercooled. For a 4.0L engine the turbo is size whise on the edge.

Even if your engine is quite "unkaputtbar" and you can stroke it reliable, it is not made for drasticale incresed intake air tempretures.
You need an intercooler. In such conversions do not decide over the price. If the price is low something is missing. Propper reliable tuning cost money, price dumping is the wrong way.
Even in the hot summer your intake-air will not increase 60 degree. With a turbo w/o intercooler ( especially a undersized one ) you will reach 130 degree ( if not even higher ), your engine is for sure not build to withstand such temperatures over a long time.
As hotter the intake-air is, as less oxygen it carries, as result you will lose HP. You might gain some HP in a very small RPM-Band, where this turbo is running in the optimum environment, but the overall performance is shrinked.
Maybe you can build a gear box which let this combination runs perfect in a spezified optimised offroad terrain.
Do not trust dyno test, it is easy to manipulate them.

I could write endless over this subject.
I just would like to give some information which you should bring into consideration.

Most properly I will join next Friday the fairwell driveout as a passanger ( my JK with 34" and original R&P has not enough power to handle the first dune ( my other 4X4, Ford Explorer, is even worse, I believe)).
I definately do not want to get stuck in my frist drive-out with the club ( even if I have all required items ready ).

If you are aswell participating it will be a pleasre for me to discuss this matter in details.

Regards,

Henning
