Some might probably remember this same car having a RB26/30 and a powerglide dummied up in it,

but after some calculations it was soon realised that this combination was going to cost tens of thousands

of dollars to complete the engine alone. So the engine & transmission were sold and the project put on hold.

Six months later i came across a low Km LS1 and Tremec 6 speed. For a laugh on a saturday arvo a friend and I thought

we would see if it would even look like fitting, the joke soon became a reality.

Factory Nissan engine mounts were used on the cross member, block to mount brackets were fabricated.

The sump did not need any modification. The factory power steer rack was removed and a VL manual rack was fitted to allow for starter motor clearance. VX Commodore 1&3/4" into 3" extractors were fitted with slight mods, just had to tuck them in a bit. PWR Radiator to suit R32 was purchased and custom shroud and fan fitted. Gearbox crossmember was fabricated

as well as custom tailshaft with masive F100 front Uni. Jim Berry supplied custom clutch and flywheel. Factory LS1 wiring harness will be fitted.

Custom fuel cell was modified to house two Bosch 040 intank pumps and plumbed up with speedflow fittings through a Russell

inline filter into turbosmart reg.

I plan on running the engine aspirated at first with just a cam and valve spring change. Should make 350kw at the wheels.

Hope to fit twin Disco potatoes later down the track.

It took about 4 hours to mount the engine and box, about the same to mount the rack. the headers took a couple of hours to modify, fuel system took about 8 hours. still have to wire it but that shouldnt take to long. could easily do it in a week if you didnt have to wait for parts to be made, eg clutch, tailshaft, radiator etc.

;) how long did it take from the initial fit to turning the key?

whats a proper V8? it makes you wonder why its been done heaps if Ls1s are shit. but u know what your talking about, ill pull it out tonight.

man it's been done heaps, ls1's are shithouse should of got a proper v8... afterall it's a holden.... but either way nice work....

Nice work mate.

How did the weight of the LS1 and gearbox compare to the weight of the RB30, geabox, front diff and transfer case?

Twin Turb's FTW, should have fit them first. :thumbsup:

I'd say the new motor would be lighter than the old one but the gearbox from the Commodore is monstrous. This car never had a front diff or a transfer case btw. :D

yeh, the engine is lighter being full alloy and having plastic intake, the new headers are also alot lighter

than the cast ones. the flywheel will also be lighter as well as the clutch assy as we are going from the standard 12.5" truck setup to a 10.5" clutch, actually using a GTR pressure plate, but the Tremec is big, think of a R33 5 speed then add 20 kilos. Its all good though as the weight is in the middle of the car and the engine sits further back than the inline six also. The turbos are something i would like to do, but want to run the car aspirated first. turbos, manifolds, plumbing, pipework, intercooler would add about 80kilos to the front of the car and would cost about $5500, not just yet. hoping to make around 350rwkw aspirated and turn the engine to 7000rpm, should be fun in a car that ways 1000kg.

I'd say the new motor would be lighter than the old one but the gearbox from the Commodore is monstrous. This car never had a front diff or a transfer case btw. :laugh:

    • Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).
    • Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers    
    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
    • Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
    • Hi All, putting the engine back together and everything is perfect except have this plug left over.. any ideas what it is for and where it goes? Is on cold side under the intake plenum *note not a stock plug, as everything has been modified Cheers
