These are not the greatest pics, especially with some at night but I thought you guys would like to see them for now.

What are the first 2 pictures? Water injection? Intercooler sprayer? Something else that is not even related to my guesses?

It is a new item for SR20's by Ben Rockwell's company, Overengineered Components. It is a oil sender relocation block. Instead of putting 2 3-way Tees on the block and having 2 senders, one input and one to turbo you conveniently mount this where you'd like. It's really great because you can see if you have any oil leaks and get to them MUCH easier than the stock sender location.

The bracket that the block is on was fabricated by my father and I. I had it powdercoated gloss black.

Those are great!!!
What type of cam took those pics?
I have a didgtal 1.3 and my pics look like butt compared to those. :mad:

Sony Mavica FD-75. They could be much better. I will take some with an FD-91 (my father's) as soon as he gets it back from my sister soon. That camera is still only marginal. Buy a Nikon coolpix 990 an up. THAT is impressive!

Nice work. Thanks for the pics!

You managed to cut up the stock fans and still use them? I didn't think that was possible. :)

When should we expect the big huge Jay Hass-like write-up of the whole install story start to finish? With problems encountered and such?

It was a real head scratcher but we made it work. We just had to modify the heat shield. The downpipe is about 1/4" away from the pass fan motor portrusion, and only that way because we zip tied the top of the radiator forward about a 1/2". Fortunately under a load the engine pulls 'away' from the motor.

More like the first draft! It should be available in paperback and hardcover. :) Seriously I had TONS of issues and still have some unresolved. (it runs great; it's secondary downpipe clearance fabrication mistakes)

Did you have an oil pressure gauge on the grey beast?

See for yourself: http://personal.atl.bellsouth.net/f/t/fthomasr/fmax/

Keep in mind I had to rig the cat *way* lower so that I could drive it. It is lower and *way* over toward the passenger side. When lifted to proper position (about 3-4 inches higher) the dowpipe slams into both the sway bar and back of the crossmember. Even pulled down as much as it is their is only 1/2" clearance between it and the sway bar and the crossmember. The turn in the pipe starts about 3-4 inches too early.

Did not have an oil pressure gauge.

Thomas:

One thing that i've always wondered, I have seen a few F-Max kit setup and I was wondering, why is the BOV connected to a tube to feed back into the turbo instead of releasing it normally? TIA

What you are describing by 'normally' is venting the air to the atmosphere. Because our cars use an air metering system, as opposed to say manifold pressure like Mitsu's-Isuzu's, etc we have to put the air back into the system after the MAF. You see once the mass of air has been counted by the mass airflow sensor, it tells the ECU how much air has passed through so that the ECU can add the appropriate amount of fuel (by injector pulse duration). So if we release air out of the system after it was accounted for (which would be without the ECU's knowledge that it is gone) it adds too much fuel and you get a rich condition. (not too mention the fact that the BOV is open at idle which would be unfiltered air *entering* the system after the filter) Plus this puff of air between shifts cycles through the turbo keeping it a little more spooled. Check the se-r archives for more detailed information.

nice install! I thought about going with painted plumbing, but I love the look of polished alluminum...:) That's a MONSTEROUS turbo! (compared to my standard T03..lol)
one question... What happens when more air passes through the MAF than it can read? I know it can only show so much air coming through....under boost, how does it read that extra amount of air? What would happen if you pull more air through than it can read? Would it just max out and stay there, or would it trigger a MAL ? Reason I ask is that I'm running boost with the stock MAF and ECU, using a Vortech FMU and pump, and MSD boost retard for timing with no problems. I was wondering what happens when the MAF maxes out, and if the JWT program "ups" the amount of air that the ECU can read/understand? Thanks

How far downstream did you mount the O2 sensor? Did you use your factory one? I'm having problems with mine....I've got it coming right out of the turbo housing... Maybe further downstream would fix that. How much boost are you running?

You run lean and BOOM. I reaches a max voltage it can give the ecu and when the air flow goes higher all it does is give that higher reader. In the meantime, the ecu doesn't know you need more fuel and your cylinder temps get hotter and hotter until it detonates.

You run lean and BOOM. It reaches a max voltage it can give the ecu and when the air flow goes higher all it does is give that same max voltage. In the meantime, the ecu doesn't know you need more fuel and your cylinder temps get hotter and hotter until it detonates. As far as I know it will not trigger a MIL.

How much boost are you running? The stock MAF is supposed to be good up to ~7psi where it maxes out, as well as the 257cc stock injectors. The FMU (have no experience with it but understand how it works) should compensate to an extent for your injector size (I wouldn't trust it over say, 11psi). I have a huge Cobra MAF that will not be maxed out at over 25 psi, and JWT just programs the ECU to interpret the foreign MAF voltage as well as provide new maps for flow over and above what the factory ECU were. I am no expert as to the specifics, but this is what I have learned by doing my homework. Experts please step in here to either correct me or add on...
