hi there,glocko here,been lapping up the reading for the last couple of weeks,great site.learning heaps cheers lex.....and every one else of course.current project is a 13 foot jet boat 93 1uzh?as in 4wd.have had a few problems tuning with programmes running too rich ,had a heap of fuel pulled out of it which smoothed it out but lost noticable power.have noticed thru other threads i have 220cc injectors ,would this be the source of mixture problems as i think for the mixtures to be so far out,especially at an idle,specs on motor must be different to others.does anyone know ?if so would upgrading to 250cc gain any thing?cant seem to find much info on the engine.am running link computor ,everything else except for manifolds and k&n are stock.also have developed a miss last time out but have new leads coming,hopefully sort it out.am looking foward to lots more great reading, and and up grades..of course.....cheers glocko...... wet stones are as good as water.......ouch!!!!

Glocko,

Can you give some details on your engine?

Where is the/was the sump bowl? front/mid/rear?

Does the throttle body have traction control?

What spark plug covers does it have (what does the sign say) and what is the logo on the upper plennum?

Lastly does it have a hydraulic fan or a viscous fan unit?

With this information we can fiigure out what you have and maybe suggest a solution.

Glocko,

What is the big hole in the middle?

From the description it sounds (sort of ) like a Crown but could be a LS400/Celsior.

I'd be inclined to have the injectors cleaned before trying to change them. 215cc injectors sound the right ones. 251cc doesn't make a lot of difference.

I checked the part # on Stan Weiss' site and it doesn't tell us capacity only that it came out of a Lexus 4.0litre. At least you know they belong there.

If you are having running rich issues, then get the ecu tuned, but get it running right first.

thanks for the diagram Peewee clears that up,they were all correct.its not running rich at the moment as i had mixtures played with allready.

Joel ,iwill have a look through threads on trigger set ups and check mine out as i have no idea on that area at this time,as for air/fuel r will ring guy who tuned it and find out if he knows,think he saved it all 4 me.
cheers

Supercharged or turbo would be easy to setup on a jet boat and will work wonders. Increasing power naturally aspirated is probably more expensive.
