    Good advice! I have a Koso Wideband AFR/Boost/Temp combo gauge coming, with the intention to put the temp sensor in the thermostat housing next to the OEM sender. The Koso has alarms on each reading. I don't know if the AFR alarm is going to be useful unless the Koso can somehow differentiate between closed-throttle-lean and dangerously lean while making power. Boost alarms are "meh", but I'm gonna like having an alarm on the coolant temp.

    I did a lot of fighting with high temps under sustained load. Used the $200 mod with the over-sized alum tanks and 2 cross spacer. that helped but I wanted better and sandwiched 2 stock radiators together. That worked.
    Options i considered was an oversized oil cooler and/or putting a 2nd small aux radiator/fan up front.

    Sand-n-Sea, if I had your welding equipment and skills, I'd be building a copy of your "double-stuff" radiator. That was inspired and impressive.

    I had an "Oh, shit" moment today while installing the low compression motor. I thought I had threaded new spark plugs into the heads previously. When I went to tighten down the first one, I hit a little resistance and put a little more torque to the ratchet, thinking I needed to compress the sealing ring. The plug sheared, right at the top of the threads. Fortunately, I have a good selection of easy-outs and an impact driver. The impact driver is really handy anytime you need to turn and push at the same time. So a few minutes later, I had this:

    Whew! That would have been a lengthy detour.

    We put about 80 miles on the Wildcat today. My expectations going into this engine build were that it would be noticeably down on power to a regular compression ratio X motor. Instead, it feels just as healthy as the "new top-end" engine that just came out.

    I did a little research and the internet experts think 1 point of compression ratio is worth about 4%. JE says the pistons are 9.5:1. My impression is that the stock ratio is 10.5:1, or perhaps as high as 11:1. I've not found an "official" specification. So I lost around 4 or 5% to a lower compression ratio and gained 4.4% in displacement. So no surprise that the "built" motor feels a lot like the stocker that came out.

    You might think this pleases me, but my honest reaction is "Hmmmmm - this thing might break too many parts once the turbo goes in".

    More to follow. Tomorrow I will clean up the Wildcat and start stripping it down for the turbo installation. I'll also be installing a combo wideband, boost and temp gauge (Koso) that will require lengthening all of the various wiring runs, so I have a bit of work to do. I'm guessing the turbo Wildcat will draw it's first breath by Friday.

    You know Im following this project sir and cant wait to get a report with a properly broken in turbo! Now that the SandShow is about over that signals the riding season here in the West. Get her done lmk when your coming down and we will go hit the dunes. Hey SandnSea your welcome to come join the dinosaur turbo Wildcats. I promise you a better trip and will not leave you back. (big misunderstanding on my groups part)

    I'll be out there as usual; mostly Ocotillo Wells. And every trip is an adventure. The most memorable ones are when unexpected happens. So in a way, unexpected makes a trip better. I had a great time with you at Glamis as always Joey

    The project went on hold for a few days while I searched for a lost part. I know I had the oil drain for the turbo when I was mocking up the system a month ago, but where it went I have no idea. So after losing a day searching all through the shop, I made a new drain and gasket.

    All of the mechanical stuff except the new air filter and the intercooler and tubing is now installed.

    I'll start the wiring tomorrow. The turbo system wiring isn't that extensive, but I have to lengthen 12 wires for the Koso boost/AFR/water temp gauge. I hate what I call "mash-crimped" connectors and butt-splices, so there will be a fair bit of soldering & shrink-tubing going on.

    The fuel controller has a manifold air pressure (MAP) sensor in it. It uses MAP to determine how much fuel needs to be added via the added pair of injectors on the shiny intake plenum. That line connects the MAP to the intake system downstream of the throttle valve. I had to drill and tap the throttle body to add the hose barb for the MAP sensor. I also added a barb to the intake manifold for my Koso boost gauge.

    Air intake: the kit comes with a small Uni filter that, to me, looks completely inadequate. I bought a Donaldson swirl canister type filter that will mount ahead of the left rear wheel. (Got a great price on the filter, but it didn't come with a mount, so maybe not so great after all.)

    Wiring is done. What a PITA!!! And the instructions completely ignored the throttle position sensor input. Thank heavens the OEM wiring diagram labels the functions of the wires, so I was able to identify TPS status from power and sensor ground. Similar problems with the MAP "converter" - the wire colors are called out incorrectly and in one case the sensor power is flagged to be hooked up to the converter and sensor ground. I wonder if anyone has fried an ECU because they followed the written instructions and not the color picture?

    I need to adapt the plumbing for the Donaldson filter and build a mount for it. Then I can reinstall the radiator and all of the plastic and try it out.

    Also, I'm retired, so I have the time to mess with stuff like this.

    I just wish I had the body to go with it. After leaning over the engine from various angles in order to do all of the wiring modifications, I went to bed early with a very sore back.
