    Need Arp head stud socket help!

    I used the craftsman 12 pt 14mm as mentioned below. The problem I ran into on a couple of them wout having a deep socket was that as the nut got turned down the stud would start poking at the socket wrench and so the socket would slip. Had to avoid pushing the socket wrench all the way into...

    Coolant Leak at Heater Hard Line Bracket under Exhaust Manifold

    You can just cut that part completely off right at the throttle body pipe. There is still plenty of firewall hose to make up the difference, then you dont have to worry about leaks...To make it easy to install the firewall hose, clamp the hose on to the pipe first while its off the car, then...

    BHG Confusion...

    I second the coolant pressure tester. The kind you rent at autozone will not fit our radiators.. but you can take a leak down tester or any kind of pump that you can control the pressure and hook up a hose to the rad overflow nipple. Check out my for sale post where I post a video of the leak...

    7MGTE build need input

    If you get your hands on a good harness with all the right pieces you will be ok. You will need a ecu too. The first thing I noticed about my 88 was the connectors were brittle even at 113k miles, it was a delicate task anytime I had to do some work and unconnect stuff, but then after dealing...

    7MGTE build need input

    Not a problem, Im actually teetering on selling the whole car vs parting it out. For your electronics question. If I were you and your kind of starting from scratch on a turbo swap. I would not even bother trying to swap a old heat dried harness with fragile connectors etc and then deal...

    mkiii fuel pump

    I was looking for some info like this: http://www.stealth316.com/2-fuelpumpguide.htm Seems like the main draw back to the mkiv pump is all the amps it draws. Everyone says the stock mkiii pump can only do this or that, still have not seen any real data... I know someone whos got a...

    mkiii fuel pump

    Does anyone know the actual flow rate of a mk3 pump and at what voltage? How much hp are they good for? Everything I find through searching is related to walbros but no one states the specific flow rate of the mkiii pump. I found a great article that says mk4 pumps are actually better based...

    Coolant Leak at Heater Hard Line Bracket under Exhaust Manifold

    I recently did number 3. I cut off the small line that feeds the throttle body. This makes installation very easy. The hose that goes into firewall will still fit on the large pipe. Im in Fl so i dont need the water going to the TB. The nipple under the manifold that feeds the other side of...

    car wont boost over 9 psi

    I believe capping off the 3000 pipe where it enters the tb helps too, keeps the air from escaping into the manifold, cylinders and exhaust... otherwise its hard to build up any pressure and there will be a lot of irrelevant hissing, Right? am i missing something here?

    intake manifold bolt leaking oil?

    thanks for checking that out. I finally took the bolt out tonight, for some reason I have a stud and a bolt switched. I applied sealant to it so that should stop the seeping leak. Before putting it back in I applied air to the bolt hole, no doubt about it, that hole goes all the way into the...

    What piston is better Probe or Wisseco?

    Im using the cp pistons. Very happy with them. Ive found various stories about piston slap with both je and wiseco when researching my purchase. Cp had the tighther tolerance spec to them I believe, and claims to have less thermal expansion. So far, not a decibel of piston slap and whatever...

    intake manifold bolt leaking oil?

    that end does go to the throttle body "tb", just like stock. theres no pcv valve like shaef confirmed. i misread first post that said simply "pcv", not pcv valve. i think its all good.
