    Nice work meinstein! Damn afr lambda sensor can be fickle to moisture. I found gauge is sensitive to water intrusion.

    wait, you are going open loop to mask a head gasket problem? If that is the case it would be easier just to fix the gasket and leave it stock.

    i stripped it down had the had resurfaced and new gasket ARP STUDS( when i took it apart i noticed 2 or 3 bolts that were very easy to loosen when i did to spec last time) ARP rocker bolts and open loop with new afr boost gauge (Going to put a bead of clear silicone around inide of face there and on back and around where it meets the plastic.. atm i am waiting on a few last detail parts to get here and running all my hoses. Started pulling in a new wire to power the gauge and will install switch tomorrow. Saturday will be bolting head back on and finish putting back and get ready to water test

    this is how i now have mine set up. This is the IS 260 so at the back right i have alot of open space where i will put strainer and a valve + hose attachment For clean out
    I also have a valve right at pump start to shut it off during clean out so that i have more pressure through engine instead of it going out reducer

    Your diagram isn't straining water to engine and oil cooler (only exhaust)???

    Any reason you didn't put the strainer before the "Y" coming from pump?

    the engine imo has alot lager holes than a intercooler.. When i took fittings out of the IC i saw debris not alot and nothing that blocks flow inside but still sea grass .. so i figured engine will let that stuff pass right through i also dont want to have strainer get so full that it blocks the flow to engine.... It was my 2 cents i read conflicting arguments how engine doesnt need to be strained and how it does but i see no foul.. Im very cautious of where i drive and whats around me the most i ever suck up is sea grass that is floating on surface

    But input would be good

    Referencing our 787 racing days , the filteration was just added because we were using 140 mikuni jets for water flow on exhaust. The 4tec cooling system does not have any orifice that small , highest risk would be bleeder on headpipe after exh manifold. The 4tec has a pretty ingenius screen built into pump for water pickup up. Basically a self cleaning screen. We dont run a sea strainer. I noticed on Chris Mac protyped SD 260 race boat we have there is no on board filter .They failed to heed water pressure regulation and it blew out oil cooler .
