Time for an update. Now running a 2JZGTE with a Holset HX52 on E50 and around 23psi boost. This setup is good for around 155km/h. With a bit more boost and wings on the front of the boat we should get to around 180km/h, time will tell I guess. The motor gets a pretty hard time in drag races like the...

Anyone running one of these hybrid turbo manifolds? Are they any good. In their listing they state that they are made from "mild steal steam pipe" however there is no such material, steam pipe is much higher tensile than mild. Anyway any experience as to how well they fit etc would be appreciated. h...

Building up a new 2jzgte motor and just discovered my crank is bent, anyone got anything?

what wolf ecu? who tuned it? my mate has a holset hx50 and wolf v500 ecu on his 1j and struggled to find a good tuner Wolf 3DV4 which is the version before the V500. I tuned this myself, I have put all sorts of ECU's into boats/rally cars etc and had no issues getting them going and tuning them. Th...

Hey thanks!!

Motors get a hard time in a race boat as often you can run 20psi boost 5,800rpm for 30minutes without lifting off. Generates a lot of heat! How do you cool it? Raw water from the jet unit goes through a sandtrap (hydrocyclone) and then directly into the water pump, water leaves the head and goes ov...

Here is a vid of our first testing. Had a Holset HX35 on it then. Crank the sound up!

Holy bejesus this thing is awesome! Being in the water means the giant turbo isnt much of an issue with less resistance to the motor? (In regards to lag) Yep that's correct as the jetunit doesn't really load up until 4000 rpm. Motors get a hard time in a race boat as often you can run 20psi boost 5...

About 2 years to build as did everything ourselves. Does about 75-80mph at the moment. Still have to play around with the trim and jetunit intake to get it flying properly.

Hi Karl here, am based in Rotorua. Here is something a bit different. A 23 foot Keelowcraft tunnel hull boat fitted with a 1JZGTE. The engine internals are standard (for now), but the head has a backcountry port job. Runs a single Holset HX-52 turbo, LS2 truck ignition coils and a Wolf ECU. Have a W...
