  1. Fail-Bucket strikes again. I can't see any of those pictures.
  2. I have been running a NA-T conversion in my 260Z for the last 7 years. It has gone through several iterations and also several bottom ends (due to me being a noob at tuning). I started out with a stock 83 zx motor / efi and added a stock T3, locked the dizzy, and added a potentiometer inline with the head temp sensor to add some more fuel. It was crude but it worked for a while. I am currently making around the 350ish HP range with a Holset HX35 at 18PSI strapped to the side of a bone stock N42 Bottom end topped with a P90 head and megasquirt 2 orchestrating everything. This bottom end has lived for about 4 years unopened with nothing but the oil changed at regular intervals. To back what everyone else has said, these motors are tough. By far the biggest weakness in my experience are the pistons. If you plan on using the stock pistons, don't rev past 6500 or else it will pull the ringlands. Also, I've lost a couple of ringlands on the pistons due to the ring gap being too tight with the extra heat from the extra compression the turbo adds. If you do crack the motor open you may want to gap your rings a little wide than stock. Granted that failure happened at higher boost pressures and horsepower than you may be wanting to achieve. As turbogrill said, a wideband is a must for any turbo venture.
  3. Low compression!!!

    I've always been of the opinion that the health of an engine isn't determined by a certain value of compression. The more important thing is that the individual compression on all of the cylinders are within a certain percentage of each other. I typically say that if the difference between your highest and lowest cylinders is within10% The engine is healthy. This is what was taught to me and makes logical sense to me, so take this with a grain of salt.
  4. Home Built Z 'Full video build'

    I love how relate able the videos you make are! Like everyone else has said, its something that one of us would be doing with our cars versus a professional shop. I have also started watching the home built house videos you have made. I absolutely love it! These are similar things that I am doing with my house/want to do in the future and it has given me some awesome ideas. Please keep it up!
  5. 280ZX "shakotan style"

    I like the direction that the car is headed. I really love the Shakotan/Boso style, but I'm not extreme enough to pull it off. It seems like you have a really nice base to start with as well, that makes all of the difference as far as being able to allocate funds to stylistic/performance mods instead of rust repair, body work, or general maintenance. I see you're in Morristown, I'm just a little ways south in Knoxville. If you need parts or a hand let me know. There is also a facebook group called "East TN Z Club" that you might be interested in joining if you aren't already a member.
  6. Time based access TPSdot and ms pulse width

    The TpsDot threshold is mainly set from the amount of noise that you have in your system. How I tuned my L28 is by turning the accel enrichment off and data logging the car driving steady state speed on a flat straight road. The data log will record the MapDot and the TpsDot. You want to set your threshold above the steady state TpsDot value so that your enrichment isn't being activated when cruising. Granted, I am using a blend of TpsDot and MapDot. I chose to go with both because of the lag of my turbo and boost onset when shifting gears. It was terrible with the larger exhaust housing I had on the turbo. (Disclaimer, that may not be the correct way of fixing the problem. I'm a novice tuner)
  7. That's insane... It's gotten to a point that I take the price of things one ebay with a grain of salt. I had a small lot of these diesel pumps that I happened upon a few years back at a local mom and pop auto, I wish I would have hoarded those few instead of re-selling them. After a quick search, this popped up : http://www.ebay.com/itm/AISIN-Water-Pump-BA010-17S27-/361779382253?epid=75011233&hash=item543bbb47ed:g:0QsAAOSw4CFY0ZX2&vxp=mtr Seems a bit more reasonable.

    I would suggest investing in a good wideband O2 if you don't already have one. They are an incredible tool when tuning and when diagnosing problems if they were to arise. With 300-350 horses your going to need to address your clutch, the stock clutch and pressure plate aren't going to cut it. You could either upgrade the clutch disk and pressure plate for the 225mm flywheel you have, or you can upgrade to a flywheel and clutch setup with more contact area. There are a few options of the latter around including the 240mm zxt / 2+2 flywheel and i believe someone makes a spacer to allow the use of an RB flywheel. The trans should live for a while (I got close to 5 years out of my 83 zx trans) but I would be looking for a beefier solution in the future. That's about it off of the top of my head, if I remember anything else I will be sure to post it.
  11. 480Z - cheap 2+2 build

    The motor is the leftovers of a warranty replacement in my dads old Silverado. From what I gather it had some issues with the crank angle sensor not picking up properly because the crank thrust was out of spec. I know that when I get to it, I will probably need main bearings. Currently the motor doesn't have an intake manifold or front accessories which really opens up possibilities as far as purchasing replacements that would work better with the chassis. I was curious about the truck intake because they are plentiful and can be had for cheaper than the ls1 or ls6 variants.That and it is rumored that they flow almost as well as the ls6 manifold. So, are you saying that the truck fuel rails have a fuel regulator at the rail versus integrated into the fuel pump? I will have to keep that in mind when I go parts shopping. I plan on fabricating my own mounts similar to yours, I can't stand paying money for something I am capable of doing with a little bit of time. Ultimately the plans for the car is to force feed the 4.8 with a T76 with Megasquirt orchestrating the whole show. If it makes 400-500 horses I will be tickled pink; I feel like that is a pretty attainable goal. There is no telling when I will have the chance to get to it though, between the house projects and keeping up my fleet of family cars I seldom have time to tinker. lol
  12. 480Z - cheap 2+2 build

    I like the quick progress! I have a 280Z that is waiting to have a 4.8 slapped in it on a budget. Did the truck manifold have any major issues fitting? I know most ditch it for the lower profile car manifold for hood clearance.

    Photobucket has completely bombed this build thread. In the next day or so, I will be replacing the images and will update what has happened with the car over the past two years.
