Got lots done the last couple days. Starting off with the thing I was procrastinating the most. Attaching the fuel line and wire harness to the PPF. Been dreading it because of how tight the space is. Fuel line is held in place by 8x 5/8" rubber P clips and the wire harness is held in place by 9x 3/4" rubber P clips. Took some patience to get in there but I got it all together eventually. Stainless 1/4x20 screws with caps hold each set of clips together. Definitely something better to do before dropping the frame on but since I was doing custom wiring, I waited. Get better pics of this later but here's a couple to give you an idea.   Finally the engine wire harness is done! All neatly loomed, tested and tucked away. I eliminated a few plugs in the process. The injectors are all tied into it as one. Coolant temp sensor tied in with the coil wiring. Quite proud of this. Now the harness comes out with the engine. Unplug the ecu and the narrowband and pull the plugs thru the firewall.    Knock sensor plug is now mounted on the back of the engine.    The FMII comes with a new AIT to use with the hydra. It mounts in the IC pipe just before the throttle body.   I am seriously considering building and selling entire PnP wire harnesses for the Exocet. More to come on this later. Gotta collect a few harnesses to convert. |

Really appreciate the feed back you guys have been giving me about the build. Couple of you were asking for more details on the FMII. Got this guy figured out tonight. It's the pre-turbo intake. Since the hydra is speed density the stock MAF can go into the trash.  Nice silicone formed tube to match the IC pipes. This was the only way I could clock it so the filter would fit behind the body panels. Note the formed vent tube that goes to the valve cover. It almost want to kink so you're limited on how far to clock it. Note it's also right up against the wastegate too.  The air filter just barely misses the sway bar. I had to squeeze the coupler tube all the way into the filter and intake tube. The filter itself also isn't straight. It has a slight angle to it as well.   Current state of the engine bay. I have to cut the BOV tube. Still waiting on my shorter oil feed line for the turbo too.  Glad I went with the FM crossflow radiator and coolant reroute too. To be honest, I'm not sure how the stock style radiators and coolant route will work with all these tubes going everywhere. There's less space between the front of the engine and the radiator than a miata so it'll be tricky. |

Nice neat build.. I have one question do you really want the air filter right behind the radiator fan blowing hot
air from radiator right into the filter..

Nice neat build.. I have one question do you really want the air filter right behind the radiator fan blowing hot air from radiator right into the filter.. No choice.  the sway bar, low radiator hose and inter cooler pipe blocks me from setting it up any lower and I can't stick it out the side because the body work will block it. |

You just got me thinking, it would be very very easy to take a sheet of aluminum and setup an air box that attaches to the frame with P-clips and shields the filter from the radiator and engine heat.
Let me play with some card board and see how feasible this idea is.

In the open bay of the exo I doubt it will matter. The intake final temperature is going to depend on the intercooler vs output compressor air, not so much ambient air intake temperature.

Nice ! I can't read it on the picture, but out of curiosity which turbo is it ? I wanted to get a 2860 or 2871 but FM does not seem to sell them anymore It's the standard FMII with the GT2560R. Ill be honest I have no first hand experience with this particular turbo or setup, but I do understand compressor maps and data. In a nut shell, the idea is this turbo will max out the engine in terms of horsepower you can make on pump gas without being so large that it has no low end torque (notice I didn't say that larger is laggy). Quick throttle response is everything on a small road course or autoX. Hell even the street! Now we will see how much this holds true after I get it together and put it out there but that's just what I gather as the reasoning for this particular turbo vs some of the larger step ups that might have come out in recent years. Quick response on pump gas without blowing up your 150k old stock motor. Sure, makes sense. However if you can read compressor maps you noticed that this turbo would not really be in an optimal place when you're always near the rev limiter, like it would be on my exocet would be since I'm only doing trackdays with it. I assume a bigger turbo would be less responsive with low revs but also produce much less heat for the usage I have in mind, what do you think ? |

Really depends on what type of racing you're doing. You may want the bigger one then (maybe even the new GTX series). Mine is more AutoX than road course so that's what it's built around (I've got a 3.9, 4.1 and 4.3 Torsen to play with too). My fear is how much the tired old engine will be able to take and the larger turbos put more strain in the midrange RPMs which is where your load is the highest. Over the summer I plan to save up for a seriously built motor (maybe even stroked) and then the little 25 will probably be set aside for something larger. ...and to be completely honest something tells me this car will be used much much more on the street than under a timer. Just made the most sense for me to start with the standard one. |

Greg.. check out Very Cool Parts build page 3 he put his filter over and in front of radiator..

The shorter ETFE 4an line came in this morning along with some 1/2 thermo tech sleeve. The new line is 4ft which is still a little long but a 3ft line would be too small and anything in between would have to be a custom line.  Decided to put some sleeving on the brake lines. You can also see I started to wrap the exhaust. |

Been getting lucky with these random Autozone hose finds. They only had silver thermo-TEC sheets there so I ordered another foot of black stuff.   |

I'd put a grommet in the hole next to the brake booster where you have the mesh loom coming through. The way it is being pulled in this pic, it won't take long to start wearing through. |
