    Some spring I was focused in ridding myself of any ebay I still had in my engine bay. The blow off valve was replaced with a greddy piece and I acquired a new exhaust manifold.

    I had found an old Redjack Racing t3 manifold in the classifieds from a partout. This worked perfectly and I picked it up for 600 bucks. Late I found a light crack in it that didn't make me too happy but that has since been repaired. The external wastegate was replaced with a tial 38mm mvs (?) And I had a dump tube and an o2 housing fabricated by BSFab. Later I discovered that I had to modify my downpipe a bit in order to properly route my exhaust. But I digress.

    The radiator was replaced by an aluminum piece and I hard wired in 2 pusher fans to a switch. I wanted my fans running all the time.

    Right around this time I contacted Scott Laird in regards to tuning. Both of our scheduals worked out perfectly. I would make pulls on the weekend and he would give instruction or modify my tune on the weekdays. It worked out amazingly and he taught be alot about pretty much anything I asked. He got my car running beautifully and helped me through some mechanical issues as they came up.

    I ran into a few issues but the biggest was surprisingly clutch adjustment. I had the unlucky circumstance of receiving a bad replacement master cylinder and it took me a bit to diagnose why I couldnt ajust the clutch properly.

    I only had the weekends to work on it and the more I got mad, the less motivated I became to work on it.

    As winter approached I began collecting parts for the next upcoming spring. Due to the car being outside, it makes it unpleasant to work on in the winter so I wait untill spring. I have since collected a new intercooler and piping, a tial bov, fic 2150 high impedance injectors, and front fenders. All of those will be installed as soon as the weather plays nice.

    As for other spring plans, I want to acquire a better catback and coilover to replace my lowing springs. Everyone hates fender flares but I love the look and want to get those aswell. Paint is in the near future and a gt3071r. Carbon hood and carbon hatch are right around the corner aswell although I will have to do some research in the removal and replacement if the rear hatch glass. A new interior is also needed and I would like to get a quality radio. Soon after, I would like to convert to awd. Part of me thinks I should just buy a gsx and swap everything over but why. I've been so far with this car already. Why not go all the way?

    Currently designing a caged front end. Reason being is I'm fairly certain the car has seen an accident. The frame right under where the factory air box should be is a little crunched and the fenders dont quite line up with the headlight nor the bumper. Some door jam gaps are a bit weird aswell.

    Any-hoo, I am designing a caged front end. I am going to attempt to tackle this myself. The goal in the design is I want it to be completely bolt in. I'm thinking, cutting the frame right behind where the air box went and right in front of the upper motor mount. Weld studs on a cap and cap off the ends. Then incorporate this front end into the center crossmember and front lower motor mount. I also want to install a tow hook and a jacking plate on the center crossmember. Everything else I want designed to bolt in place at relatively normal locations. Intercooler, radiator, ext. I also want to encompass a proper mount for my external oil cooler and my horn.

    I dont know if this will happen soon but I want to at least start collecting materials this winter. I also need to brush up and practice quite a bit with welding as I'm not very good at it.

    Material wise I am thinking a mild steel. Due to it being easiest to weld and you can just MIG it.

    Bad thing is whatever I end up doing and when i do it, it will be outside since I dont know anyone relatively local that owns a garage. I will post up some drawings once I'm done. I normally like to just "wing it" but material isnt cheap and im not made of money.

    Pusher fans dont work. They scatter the air flow because air will deflect off of the solid pieces of core and come back out towards the fan. You can verify this by feeling the fan pushing out air by holding your hand to the fan as it pushes.

    Dual core radiators are a complete waste of money and space in the engine bay. The cooling system is only as effective as your thermostat and fan settings. The dual core thickness can also cause an air pressure build up behind the intercooler and decrease the intercoolers effectiveness by reducing the air that can pass through it quickly to transfer heat.

    Not that it matters in new england or anything. In texas I noticed increased temperatures after adding a dual core aluminum radiator to a car. Just wasn't effective at quickly transferring heat like a single core oem unit. Also noticed fans ran constantly because they were less effective at pulling the same volume of air through the radiator

    Nice build

    New turbo is on the way. I decided that I wanted to rid myself of the hx35. It pulled like hell but it doesnt exactly make power where I want it.

    I had origonally gotten the hx35 in the beginning of the build. I honestly should have went down the path of a 16g or maybe a 20g but is what it is.

    After alot of research and a few recommendations from local friends I decided to keep the t3 manifold and I went with a PTE 5557 with a .63 A/R 4 bolt exit. Spoke on the phone today with precision for clarification of oil feed psi. PTE claims that, for this unit, no less than 15 psi of oil at idle and no more than 150 psi of oil at WOT. So it's looking like I wont need to restrict the oil feed like from the OFH ether.
    ^correct this if I am wrong.

    Turbo came in today. Next paycheck I will be contacting Morrison fab for an O2 housing and then install will begin.

    Currently deciding if I want to keep the RedJack Racing t3 manifold I have and get a new o2 housing made or if i want to get a new manifold/hot parts from morrison fabrication.
    The RJR manifold has cracked once before and I sent it to a local friend of mine who repaired it. I have heard that if a manifold cracks, it will over and over again. Anyone know for sure?
    Ether way, decisions are to be made soon.
