My mates in the process of building an RB20DET powered boat :cheers:

I thought that was pretty cool for something different.

Hes already got the engine and is working on it now..

Hes puting a rebuilt and hiflowed T04E on it with bigger injectors and a huge FMIC.

I pissed myself when he first told me and thought he was playing around... but hes serious cause i went round and he had the boat there and the engine pulled apart.... should be fun when its done :D

Yeah, what sort of boat?

If its a ski boat, it will effectively ruin the boat and make it drive like crap. You need instant and enormous amounts of torque in a boat, from standstill, thats how you pull skiiers up. Thats why almost all boats using inboards are V8's - Mine uses a Holden 308 and it can sure boogie. I couldn't imagine being pulled up by something that took 3 seconds to get any power, it would also be a piece of crap to try control while trying to pull a skiier up.

On the other hand, if its a rear mount speedboat with no intention of skiing, wakeboarding or other related water activities, it could be a very interesting job.

I'm planning on twin turbo'ing my boat, just imagine the sound of a 5 litre V8 with no muffling, basically straight through 3" pipes from each V, while spooling up two turbo's - you'd be in two heavens :)

Imagine? There was a twin turbo 454 with open pipes that turned up at one of the dams we used to frequent. It was a friggen unit, had a 3 speed auto behind it too... boogied reeeeeal hard pulling skiiers up (I have no idea how they didn't have their arms torn out of their sockets), then you'd see it almost idling along at like 50 knots next lap around. I think from memory it was called Far Canal or Far Kme or something along those lines... whatever it was, I remember thinking "how appropriate" :)

Revhead, we have an event down here called the Southern 80 where the whole competition is which team can pull a skiier along an 80km distance up the Murray River.

Most of the boats end up having things like twin T88's and bigger on monster 454 and bigger blocks. I think the record was in the mid 30 minutes to complete the entire lap, with a skiier behind you! If I'm wrong someone please correct me here...

But man..... words can't describe it, I've got a handful of pictures of these monsters from this year here:

I saw a similar boat and setup at racepace last year when i was there to get a tune. But it was a twin turbo 350 chev pulling close to 1000hp. Looked like the guy had spent all his $$ on the boat coz he a a shitty old xf tow car.

lmao nope its not going to be used for anything like that... tis more just a project thing... hes had a few in the past few years including a 10sec RX3 and some orange XW fairmont with XY GT running gear and stuff rebuilt... i liked the ford better of the 2... looked horn with these huge deep dish 18" rims...

wont be towing anything on the water... just a fun thing.

      M35 Brake caliper replacement

      By Duncan · Posted

      You can use your VIN to look up the factory part number somewhere like amayama, and then look to order new if necessary. https://www.amayama.com/en/genuine-catalogs/nissan Depending on price you might want to rebuild instead. @GTSBoy I had an interesting insight into US market parts when the Titan rear calipers were sticking. New calipers were dirt cheap, about 20% more than a rebuild kit....they are just considered throw away maintenance items

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

      By Duncan · Posted

      Lots of votes for driving onto a plank first; that is the quickest way I've found, 25mm is enough for my case but that will vary by car It also depends where you are going for. On the 32 I can get to the rear diff with my floor jack if I do that end first, and get it up on stands. Then I lift the front from either front tow hook as high as needed, also onto stands. Sometimes I need a small lift on the other tow hook to get it level enough If I do the front first I can't get to the rear diff because of the angle of the car Other options are getting to the front mount of the rear subframe from in front of the wheel (if only lifting one side, or just do both which is a bit of a pain compared to one lift from the diff), or also the gearbox cross member mount on the driver's side if you are  just trying to lift the driver's side. I This is the jack I use; it says 75mm clearance but of course that is only on the lower section so if you have to reach too far in like the diff you still get stuck. https://www.snapon-bluepoint.com.sg/category/Floor-Jacks/product/Floor-Jack,-2-Ton-Low-Profile

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Ok so i will NEED to have this sensor anyway even with Nistune (or standalone ECU) https://justjap.com/products/genuine-nissan-boost-pressure-sensor-evap-control-system-fits-nissan-r34-skyline-c34-nm35-stagea-pnt30-x-trail-rb25det-vq25det-sr20vet?currency=AUD&srsltid=AfmBOoqfxX48bW9bEwH62orcNhtBfp7ekAL0C9Ca89ySFGUiBzXfXeze Is this the correct one? And this is only thing i need? No other "things" connected to the sensor or something? I do have the wiring.
