    bwalt's MSP build log

    I was able to take the protege for a test drive this week since the weather warmed up and melted all the snow. With the new compressor housing and old bov reinstalled, the turkey noises are completely gone. There is a very nice, non excessive, compressor whine now any time the turbo is...

    Got my pinion shaft back from the machine shop today. They did a very nice job grinding the bearing journals. Here's the full PAR 1-4 and MFactory 5th gearset. I am so stoked to get this transmission assembled and in the car!!

    New compressor housing for the EFR 7163 arrived. It's the SX-E version which increases the inlet diameter from 2.5" to 3.5", adds anti-surge ports and eliminates the integral BOV. Reason for swapping covers was due to lower rpm (sub 4K) surging and fluttering, reminiscent of the stock MSP...

    Need help fixing my MSP

    Stock MSP turbo is a Garrett GT25 with T25 .64 turbine housing.. As far as I know, a rebuild consists of replacing the center housing rotating assembly cartridge.

    Great news, the new clutch is holding! I've gone all the way to 20psi and man oh man does this thing haul!! 400whp is the goal. I think after tidying up the AFR's and some more boost, it will be achievable.

    New clutch arrived early last month. I chose the Spec Stage 3+ MSP version. It's installed and broken in. Sure am glad I went this route. Streetability is fantastic, even with the lightweight flywheel. Pedal effort has increased but not an uncomfortable amount over the NA Protege clutch. Time...

    For Sale Spec Stage 3+ Clutch Brand New fits Protege, P5 and MSP

    Brand new unused Spec Stage 3+ clutch kit. This is the NA protege version with 429 flywheel torque rating. One of the best performance clutches I've used. Pedal feel and streetability are fantastic for a sub 300wtq protege. Reason I'm selling is I now make more power than this clutch can...

    Intermittent Electrical Overcharging

    Just tug on the center of the belt between the water pump and alternator, it should have a little slack and you should be able to twist the belt with your fingers about 90 degrees. Too tight and you'll put excessive strain alternator bearing, water pump bearing and especially the crankshaft main...

    Intermittent Electrical Overcharging

    Usually a squeal is heard when the belt slips but I'm some cases it won't. It's easy to verify belt tension with the engine not running.

    Intermittent Electrical Overcharging

    +1 on the aftermarket alternators being no good out of the box, even the so called 'new' units. Denso reman probably your best bet. Is your belt tight enough? Could be slipping at higher rpm. Alternator charging control is through the ecu if I remember correctly.

    I just did a couple warm up/cool down cycles and the air seemed to burp out as it normally would. Topped off the radiator afterwards. At some point I will probably put a heat sleeve over the lower hose. Exhaust wrap on the downpipe already does a fantastic job, one more layer cant hurt.

    Manifold is wrapped. Turbo efficiency is up, under-hood temps are down. Also starting to remove the lineup of gauges across my dash in favour of a haltech can gauge. The individual gauge sensors will then be wired to the ecu for data logging and engine protection.

    TheMAN's Turbo LHD Sport20...err MSP Conversion

    Very nicely put together. You have all the goodies from different markets and some rare upgrades. Probably the best example of an OEM+ setup Protege imo.
