Precision Turbo Kit Part 1 - Components
This is the first part of a series on the Precision kit.
I got my Precision kit last night and went through it. Here are the first impressions:
The air filter is a pre-oiled conical K&N unit - that thing is HUGE! The filter is connected by 3" tube to the GT28R.
All cold tubing and the (cast) plenum are aluminum. All tube ends are bead rolled. I only found one welded connection in the cold tubing - in the center of the 3" air intake tube. The charge tubing consist of 3 pieces total of 2" tube, plus the cast intake plenum that goes from 2" up to ~3" or whatever the throttle body actually is.
I didn't see anything in the way of support tabs or brackets for the aluminum tubing so we'll see how that turns out during the install.
All hose connections under 3" diameter are by T-bolt clamps, 3" and over use worm type clamps but of the style that does not cause the hose to exude out through slits in the band.
The intercooler is 18" x 6 3/8" x 3.5" and has cast end tanks. I am a little skeptical about the wellnut mounting method for the intercooler - I may add a supplementary mount, or just substitute nuts and bolts where the wellnuts are supposed to be used.
The header and down pipe are stainless coated with titanium of some kind. The finish looks very nice. The down pipe is 2" in diameter. A header-to-head gasket is included, gaskets are not used on the header-to-turbine or tubine-to-downpipe connections.
There is a stout bracket that supports the lower (turbine end) header flange by bolting it to the block. It appears to be ceramic coated - looks very nice.
The internal wastegate actuator has a threaded arm to allow some boost adjustment. The instructions explain how to preset this arm for 8-10 PSI.
Oil is carried from the back of the block (by the starter) to the turbo via 2 prebent hard lines. Oil is returned by a Hitachi oil pump (Edit for those that have enquired: "Hitachi T-Type Oil Pump, 742-4839" - mine also says MFG No. 000151 which may just be a serial number) via braided stainless hoses that are terminated with real pressure connectors - not faux aluminum shielded hose clamps. The pump uses a simple 2 wire connector for power. There is a US made "Digi-Set" timer/relay of some sort that will cause the pump to run for a few minutes after engine shut down.
A new Ford oil seperator is included. It has a threaded nipple TIG welded on for the oil return line. Here is something for you Eric - According to the instructions it also must have some kind of modified or alternate PCV valve as it is warned that the supplied one must be used instead of the factory valve (?)... the part number of the supplied valve is AC Delco Type CV-893C.
There are some beautifully done prebent stainless hard lines to plumb water into and out of the turbo.
All in all it appears that someone went to alot of effort to try and ensure the component quality was about as good as could be sourced. I am left with a very good first impression of the parts and materials selected.
One hang up I found so far - my car does not have air conditioning and the oil pump bracket is designed to bolt to the AC pump. I guess Foci without AC are rare? This means that I will have to fab up my own bracket. Not a big deal, this will actually work in my favor as I will be able to gain a little ground clearance (I have a Cup Kit suspension) by moving the pump back closer to the block, but something potential buyers should be prepared for. Precision is express shipping me a longer oil return line (no-charge) to allow this relocation reward.
