Here is a pick of my own design manifolds that we do for the 1uz motors, they feature the largest flow through the riser of any on the market, These are designed to match the motor ports and not overlap them as some others do. we have around 100 Lexus conversions into Boats under our belt. We can supply turn key marine motors to all parts
Manifolds $1395+gst
Microtech computer with loom and tuned computer, This is a plug and play loom, $2100+
CNC Drive blocks $145+

We are now welding them as one which means no gaskets so no future leaks and we can allow for O2 sensor ports. We lean them in to help with room in the engine bay.

This is good news! Another question: I need the parts that are attached to the cylinder head, the second part of the knee is not needed. Is that possible? If yes, specify the price for the kit and an approximate shipping to Russia, Vladivostok (the city from the Sea of Japan). Best regards !

Hi, Yes we can send to Russia we have sent a few sets over there. The first part (the part that bolts to the engine) is $750nz (both sides) and the riser is $645nz (both sides)

It takes around 2-3 weeks for them to be freighted to you.
Payment can be by credit card or bank transfer

I have numbered the parts to the manifolds to make it easy for overseas customers whishing to only order for example the manifold (1) but not knowing the what to call it in their language. this should help any confusion

Hi Mike

Tell me, what benefit will replace the factory to the new Microtech computer with loom and tuned computer, this is a plug and play Loom.
What do I get on the boat if I change it?
Will the fuel economy while maintaining the same speed or increase it?

You can see the photo looks like this set Microtech?

I have never seen a lexus engine run correctly on the factory computer in a boat, we tried years ago and gave up. We are now using the Link G4 aftermarket computer and have had a good run with them. The good thing is that you can down load the software yourself and make changes or check for faults from your laptop. Fuel use depends on how you drive it but it is normal to be between 18 and 24 LPH normal river boating, Some see as low as 14 to 16 at a steady cruse

Hi Mike,

I'm planning to fit a Lexus 1uz in my boat, this engine will drive a Berkeley 12j Jet. What would I need to marinise this motor? Computer? Cost? Will you ship to South Africa?

Hello,
for my jet boat conversion I still need an exhaust. I want to run my boat in the ocean....will the aluminium resist salt water? With the conversion now my engine sits pretty low. Are there other risers available that have the outlet as high as the valve covers?

Best Regards
Hans

Hi Hans, Our manifolds can be run closed loop (part of the heat exchanger circuit ) as long as the heat exchanger is large enough to handle the extra heat, That means that the salt water is only going through the riser. Our risers are quite high so I would not see a problem with a low mounted engine

I think to run the manifold closed loop should not be a problem. I'm using the heat exchanger from MERCRUISER for 5.7 liters.
But with the standard risers the outlet tips will be under the waterline as in 1st pic.
I think it's better than in 2nd pic and get welded some special risers here locally.
What's your recommendation?

Yes I agree making a riser would be better if the engine is that low

Hi Mike,

I'm wondering where should the water enter and exit log type manifolds with risers??

Should it enter the bottom at the front and exit the top at the rear (so the water will fill the void) then go to the riser

OR should it enter the top at the front and exit at the bottom at the rear (so that any sand will be flushed through the manifolds)then go to the riser??

Can you draw on this pic the water flow??

Cheers Dan

Thanks Mike I'll make the water enter the lower side at the front and exit the top at the rear then go to the Harris Marine risers. This way I can back flush any sand out of the manifolds by pulling the hose off the riser and put the hose into it if needed.

Cheers Dan
