What would be the best engine swap for a 350z and possibly still retaining the stock 6sp gearbox?

My opinion is a RB26 or 20B ROTARY :OMG:

What do you guys think?

Im looking at options at the moment as the car will mainley be used for drift

An RB25 or RB26 is your best bet if you're doing a complete swap. It's really pricey and I don't know anyone other than big sponsored companies that have done it. Good luck finding someone that can do it for you; I'm guessing it will be a bigger headache than it's worth. You'd have to replace engine, engine mounts, tranny, driveshaft... :headbang:

Building your VQ with twin turbos and forged internals would be much cheaper than the swap and you would have more power for the money you spend too. :thumbsup:

why are you interested? Weight? Go with an sr20DET if you are really interested in saving weight. The Signal Auto drift car saved an estimated 600-800lbs .I dont know how realistic these numbers are, but that is what is stated in the article.

Just because the SR20 has two less cylinders, don't think "lighter".. remember it is a Cast-Iron block. The weight savings is actually negligable from that angle.

For a drift car, IMO, I'd rather a Q45 block. Port, polish, bore and stroke. Instant steady torque - no turbo's to have to keep ahead of and continually modulate to keep precise power. N/A is the way I'd go for drift applications.

Ive done some research on the topic. With an rb26 swap you will need an rb25 transmission...these combined will run around 4g's. Being a cast iron blocked motor it is far heavier than the VQ which would negatively impact handling. Im sure its a headache with the custom fabrication and fitment issues...but I think it will run about the same $ as a built and turbo'd VQ. Plus you can always sell your VQ to fund the project or keep it in case you decide to throw it back in. As far as the sr swap, Ive seen the article that toykilla is refering to.

Why would you bother with an engine swap when the VQ engine is such a good platform for high power?

Seems to me that you will trash the resale value of the car if you swap out the engine, food for thought. :cheers:
