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.

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.

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

      By MBS206 · Posted

      For race cars, this is one part where I find having the roll cage bar having gone through a hole in the floor better than the build it up on a ledge inside... The Merc I help on, the main hoop ends are marked on the car, and the jack is marked... Jack goes under a few inches and lifts one whole side of the car up... Removes that fight for long slim jacks for race car duties!   My biggest issue for the daily drivers I work on, is my jacks don't go high enough. The jacks start out on a few blocks, jack it up, then start a second jack under it on more blocks, and then I can get an axle stand under it. My axle stands are presently in use, and are nearly fully extended. The car is sitting with barely more than a cm of clearance to get the wheel off the studs! Sarah's Kluger is the same, as it has an ungodly amount of droop available in the suspension and a distinct lack of good jacking points!

      Happy? Yep, my to do list is getting shorter and shorter. Either this light approaching is the end of the tunnel, or I'm about to be hit by a train... Ha ha ha   Also, Duncan isn't that far out of town that you need to make a multi day drive out of it. 😛
