Why not a 13Bt or even 20Bt. 13B is a bit shorter than LS1 (not sure on weights) so would have better weight ditribution, not to mention a heap more room to move. Only thing you have to watch here is the rotary's exhaust outlet down low on RHS can foul the steering rod-box-lines, although this can be overcome.

You wont match the LS1 torque curve for driveability though !

having been a rotary owner including a 350rwkw series 6 built by supposed best rotary guys around..... i would say its a bad idea...... rotary's are way cool.... but one one rule always stands true ---------->braaaaaaaap BANG

ahahaha, damn you beat me to it. i have a mate with a rx7. seems to be that you don't service them every few months (or 5000kms), you rebuild them, LOL. he once had to rebuild it after 6 months and it hadn't even been started.

A gun conversion is the VQ30DET into said skyline.

They go hard, all alloy, torque, modern stuff vvt etc.

Conversions have been done for a while now.

I am currently doing a conversion on a mates 180sx, VH45DE with a 300zx 5 speed.

dont do a v6 supercharge. you gotta be on some seroius drugs specaily to dump in a v6 from Holden ,single cam, push rod valves over 50 year old technology. ls2 makes say 300kw, 5.liter. a rb26, with less than half the capacity makes 206kw. do the maths

Really it's up to you whatever you decide. considering you can buy a LS6 in the box for under 4k now. turbocharged 8's are hard to beat in respect to torque and power. but really if your gonna run an 8 you wouldn't need to charge it either way unless your after some serious grunt.

would need some fabrication and alike to fit but if thats what you want....

personally i think the RB can provide ample enough for anything. if you want bigger torque and power i don't think much better value comes than buying a complete 25DET head and buying a good nick RB30 and switching the heads over. that's done in under a grand and leaves you with the same limits as a stock 25 + a bunch of extra torque. If you want to change turbo's etc it's preference.

but i don't see the point in putting a holden v6 in there, sorry.

I would personally go VH45DE because of the 6 bolt mains, the fact that it's still a Nissan, and the SOUND!

I can see the logic in going the Chev route though, really a V8 Skyline of any sort is going to make people go wtf!?

What about a 2JZ, thats a six!

myself personally would go either the VQ30-35-40 or LSx, whats a 2jz + 6-speed worth these days?, my guess is that it would still be more than a brand new crate 6.0 chev and 6-speed, plus you can use the standard ECU unlike the toyota so your saving 2k there already....the list of Pros for the LSx Swap is massive, espesially when you put prices next to each other.

    • Yes. You will need to get the original boost sensor and wire it in. That is.... if you plan to use a stock ECU - even a Nistuned ECU. The Nissan ECU will not operate correctly without it connected. And yes, it will do annoying stuff like you are experiencing. You will almost certainly be better off with some aftermarket ECU, than trying to hunt down rare sensors.
    • Ok so ABS/TCS is "not" the problem. Yeah i know now about the ABS with Nistune(i told that to the Nistune guy) but iam not 100% why or why i dont have ABS. ABS cube is in the engine (always has been) but i had braked couple of times rly hard and brakes just locked and scream. Does all Skylines have ABS cube? That boost sensor https://www.sau.com.au/forums/topic/367633-wtb-r34-gtt-turbo-pressure-sensor-pics-inside/ Is this it? I need to ask but i have a picture of engine bay and i do not see that (100% is not in that place) If i do not have this the car can do what mine is?(cutting around 4000 rpm) Here is the pic of my engine bay(only one i have) BUT i think i dont have that cuz loom was used from my RB20DE NEO and i know (obviously) that it does not have boost control or any wire to that...) so maybe that is the problem? (i dont know for 100% if that car where the engine is from had that)...but i dont have the loom from that
    • I'm with you here. It's either loom has an issue, OR, injectors are not functioning properly. It could even be they're just constantly dribbling, hence the wet, but not firing.
    • Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi
