Just wondering every bodies thoughts here. A lot of talk in the USA re the go is forced induction on V36 (7-9K USD) but here in OZ its too dear to import a kit and if you do, you can quickly run fowl of the law and get a defect notice as the V36 didn't come stock with turbos. Ideally an engine swap may be a better approach as you can re engineer to be safe (brakes, driveline) and obtain compliance & fuel emissions. The new motor needs to be the same year model (or later) as the donor car or else hassles with fuel emissions (so no old RBs please).

I can see a few options but lets discuss if you have seen these fitted (locally or OS), how hard, costs and see if we can find a sub 20K winner?

 

Option 1 - QX80 motor VK56VD Also found in nissan patrol. 5.6L V8. V8. Used in Supercars Championship in 2013 by Kelly Racing in Melbourne. QX80 sits on same FM chassis as the V36 sedan so i assume a direct swap in. Stock trim @400 hp (298 kW) and 413 lb·ft (560 N·m) of torque. has uprated 7AT to cope with torque compared to V36 7AT. So just how much power can be got from this quad cam V8 ? The V8 supercars got 650 hp (485 kW) 657 N⋅m; 485 lbf⋅ft.  A flat plane version in japan gave 800ps. 

Thoughts - GOOD: cheap, local stocks, common, easy to get serviced by nissan locally (QX80, patrol), comes with beefy trans. ECU and car electronics should be interchangeable with V36 sedan IMOP.  BAD - nose heavy, gas guzzler. may not clear bonnet or sump too low (maybe not as i read its basically an VQ37 with two extra cylinders)   

 

Option 2 - R35 GTR 3.8TT motor - VR38DETT V6 I dont think we need to spend too much time talking the virtues of this block ! Power ranges from 357 kW (485 PS; 479 hp) to 419 kW (570 PS).

Thoughts - GOOD: Block can be built to handle impressive power (some claim 2500HP). BAD - not cheap !. It would be very similar to 3.7 block, the GTR block was designed for AWD so not sure how to mate to existing trans selections? I think this is just a 'too hard' option.

 

Option 3 - Q50/60 motor VR30DDTT  I read this motor is the baby GTR motor and that got my attention. Its slightly different from VQ in that it uses direct injection and has compact turbos integrated into the manifold I read. Comes as  300 and 400 hp (224 and 298 kW) and has uprated 7AT to handle power 

Thoughts - GOOD: This block and trans may actually be affordable. I found one on ebay and no doubt a JDM importer can get a front cut with one from japan. Fit straight in place of VQ37VHR and should match weight so no imbalance. Smaller displacement means slightly better fuel economy off boost. BAD - its a new motor so not much known about it. Tuners are just now getting 500-600HP out of it in USA. Also ECU and electronics wont be compatible with V36 versions so some serious electronics work is gonna be needed to make it work. I could even see both ECUs ending up in the car wired to various but different systems like radio/gps, radar cruise, speedo etc (V36 + Q50 ECU)

None of those make sense. The only option that makes sense is LS1/2/3. Whatever the largest is that will go in under NCOP. Simply obscene amounts of power made easily and cheaply. Much more compact and light than any of those massive Jap engines.

Oh, and manual. Man's engine means man's gearbox. None of that auto weenie transmission stuff.

This actually isn't true (having just legally done a LS swap into a skyline). It's just that the IM240 emissions regulations are based on the year of the car. That's the target you have to hit.

This generally means that if you use a newer engine, its far more likely to meet newer emissions regulations, which get more stringent over time. (also the R33 is 1/4 the limit of the 'hard to hit' variable that the R34). So put an LS into a R33 lol.

In regards to what this thread is about, LS is always the answer. It is a hard enough swap unless you are an electrical god damned genius to attempt any of the things that would go into a V36. I would say its probably simpler to go turbos, or the even more boring answer, is find a better platform because the V36 does what a V36 will do as well as a V36 ever will. There's also probably* kits out there to put LS's into the USA versions of the V36. They may or may not be suitable.

Note: You could probably pass the emissions IM240 with turbos if you wanted. This is a NSW/VIC regulation but every other state is more lenient than that. I'd still advise against it because you're stressing a motor out, when there's other options that do not have that issue.

Oh, I listed motors that have been fitted top the FM platform so stand a good chance of bolt up (engine mounts, gearbox). LS1 sounds like serious surgery. Agree with ECU that its getting way harder thesedays

      Mistakes were made, my R34 Story

      By Duncan · Posted

      Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
