The new Boss V8s have me scratching my head. AT 6000rpm the piston speed is something like 5m/s off the piston speed of a F1 engine. And maybe the heads are off the Jag, but its not the same engine, the block is out of a sports utility/truck

The stroke is just too long (its a truck engine after all) to rev hard. That said a blower would be nice.

Id say they are awfully expensive and an unknown quantity as far as width which might eliminate the possibility of turbocharging.

I doubt you will see many turbo Boss BA Falcons getting around, if you want to change the headers you have to remove the engine.. its that tight a fit so i dont know where the turbos will go.

Reality check guys why would you even think about the motors youre talking about when the legal, nissan made, realistically priced, far superior in build quality,power output,cost of modifying to achieve awesome HP and fitting ease is available ? The only thing better than 1 Q45 is 2Q45 now i could put the other in the boot and have a 2000HP 4 wheel drive ?????????

Andy32; maybe you dont have any idea about the lt1 or l98 engine but it is extremmly easy 2 get 1000rwhp with a singel turbo setup.

Their is also alot of displacment setting 2 choose from and i remember someone telling me that "cubic inch wins races"

but then again i dont know much about the Q45, so i can't say the l98 or lt1 would be cheaper ect.

Mork calling Orsen, if you haaaave read the regs with turbo 3750cc without 4500cc ,how do the chev and ford motors fit these specs find out about the Q45 and you wwwill run to the bathroom and wash your mouth out mentioning holden and ford and Q45 in the same message.PS note the caps.

Not 100 percent sure here guys but i was of the impression that two of the reasons we all love skylines is that they actually stop and handle nicely. I thought the Q45 was a good idea,(good power, reasonable weight) but surely there would be much more expense involved in the brake and suspension set up if you were to throw a chev in the engine bay. Unless of course you only want to go straight. One other thought i had was that, I for one have moved from Fords/Chevys to imports because of the more advanced design and reliability of the japanese motors and management systems. My opinion : Go hard with the jap v8s forget about the others, they suit the Falcadores better.

Now thats off my chest i can go to work :)

Cheers

^^^u said it dude, i know that it would cost alot more with a heavy chev in it, but we all dream about things, and i would do it in the drop of a hat if there was nothing to comprimise, but as it stands the the Q45 engine would be awesome, i have more than 50kg's or stereo in the boot so in a rough dodgy sort of way it kinda evens out, And i cannon on either side of my rear bumper seating at the lights burbling away, im not sure people would no what to think.

ANDY;

JUST TO LET YOU KNOW HOW VERSATILE THE Q45 ENGINE IS I KNW THIS GUY IN SYDNEY WHOS GOT A SHORT WHEEL BASE 300ZX WITH A TWIN TURBO Q45 IN IT. I THINK IT CALLED A 300ZX GT OR THE LIKE. APPARENTLY HE GOT THE CAR FROM AN IMPORTER ON THE NORTH SIDE WHO GOT IT IN FROM JAPAN AS A STOLEN AND RECOVERED. THERE IS SOPPOSED TO BE A COMPANY IN JAPAN DOING THE CONVERSIONS. NOW IF THEY CAN GET THAT MOTOR INTO THAT ENGINE BAY I THINK YOU COULD FIT ONE IN JUST ABOUT ANYTHING.

The 300ZX despite being a cramped engine bay was designed for the width of a quad cam V6, whilst the R32 for a SOHC-DOHC inline 6 cyl.

What that means when you break out the tape measure i dont know but i suspect for width the 300ZX has a bit more space then an R32.

How did he get the twin turbo VH45 300ZX complianced, or is it a race/rally rego import?

Roy I am hoping for min. 550hp that 300z must be quiteeee a weopon I also wonder how he got it complied and registered I have never heard of it being done I have two mates who go to japan every couple of months and are right into performance so I will get them to check it out.Funny about the weight as the body hasnt dropped much if at all compared to the turbo 6 it actually had an rb25 in the car before,but the weight is actually sitting further back compared to the 6 now.

Birty, I dont have exact figures, but i can get hold of them from my mate whos doing a v8 silvia conversion. His research concluded that the VH41DE (not the more recent 45) is merely 50kg heavier than the CA18DET. The RB is clearly heavier than the CA so im guessing the VH might be well under.

    • My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
    • 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.
