I'm looking for some gauge pod recommendations for a 1g. I'm currently running a single A-pillar gauge pod for my boost gauge but I've recently purchased a wideband kit and I'm looking for options to mount the gauge. I may want to add more gauges in the future, i.e. oil pressure, fuel pressure...

I'm looking at this wideband kit on Amazon*: Innovate 3796 LC-2 & Bosch LSU 4.9. As best I can tell, this is a comparable kit to what ECMTuning lists on their site, but LSU 4.9 instead of a 4.2 sensor. Does anyone see any problems with this kit for a 1g DSM? Are there any issues by running the...

My valve cover tends to leak along the front side of the head. No matter what I do, I always find a bit of an oil leak coming from the valve cover gasket area. Sparkplug wells are dry. I have all original OEM hardware, no stripped bolt holes and original valve cover. Sealing surface is clean and...

I've been having an intermittent no-start no-crank issue for about 8 months now, or since rebuilding the engine. I turn the ignition and sometimes a short pause then it cranks and starts. Other times just a click and I have to try over and over until it finally engages. Most of the time it's...

I'm looking for a 1g AC Refrigerant Pressure Switch MB568179. I believe this part is discontinued. My research shows it has a 3/8-24UNF male connector. I see some knockoffs on ebay but the electrical connector would require some modification - doable but not my first choice. Does anyone have any...

I'm installing a FueLab 515 fuel pressure regulator in my 1g and I'm reading some conflicting information about what to do with the stock FPR solenoid. Do I keep the solenoid in-line with the vacuum/boost source or eliminate it?Some say to leave it in-line for better startup conditions, others...

I've attached a data log of my commute to work this morning.I've been experiencing lots of knock under low load, part throttle, ~2k-3k RPM, and usually open loop. In this log, knock continues into closed loop for a bit. I have to release throttle and roll back into it for knock to stop, and...

I'm looking to upgrade the fuel system on my 1g. Currently running a stock system. It seems plenty has changed with injectors specifically so a lot of my research is outdated.Applicable mods: ECMLink Rewired fuel pump Fresh engine with 8.5:1 compression Future mods: EVOIII 16G, Exhaust...

Since more and more OEM parts are becoming obsolete/NLA for the DSM platform, what aftermarket brands of replacement parts do you trust to be as good or better than OEM? Maybe even an OEM supplier. For example, if I'm shopping RockAuto/Amazon/my favorite parts store and I see Denso, NSK, Aisin...

In my 1g I've been smelling antifreeze when I turn the hvac thermostat to heat after the engine is warm. I'm always using fresh air intake and the blower is always on. Only very briefly is the smell noticeable and only when heat is on.Water pump and all the hoses are new. I have an...

I'm testing out a stock 1g ECU (1993 EPROM) and discovered it has no idle control. I know it's the ECU since my original ECU works fine. It doesn't fast idle on startup, compensate for any electrical load, nor does it compensate if I turn the AC on. My logger shows the ISC steps moving, but no...

I'm 100% sure these are reposts, but always fun to see them again.

Found this hanging out behind the front crossmember. Anyone recognize this clip?

My 1ga hood sits a little off the rubber stops on the left side and doesn't align with the popup light. When it's latched I can push it down and it'll sit flush with the popup but springs back when I let go. Seems like the hood is a bit warped, maybe from too much time on the hood prop.Anyway...

For a 91 AWD Manual, does anyone know what the correct Anchor or other aftermarket replacement part number would be for the engine rear roll stop (motor mount)? It's MB436495 from Mitsu.I've now purchased two rear roll stops that do not fit. They were both listed as compatible but the bolt...

Discovered my cam gear dowels are bent when reassembling the head. Decided against using them since I had another set. These are OEM 1g cams. Nothing catastrophic happened when I last ran them. How would camshaft dowels get bent like this? If I want to salvage them, where can I buy new dowels?

What is the minimum thickness of a 1g head to still run an OEM headgasket without piston to valve clearance issues on a stock/OEM build?I *believe* my head was never milled previously and the machinist had to take 0.008" from the deck. From my research, this is the max amount according to...

I've been scouring locally for a shop that can machine my 1g rods to fit 2g pistons and install the pistons. The shops who have responded do not instill confidence. One was asking me about bushings, which I do not believe exist on 1g rods.So what machine shop can I ship my pistons and rods to...

Looking to replace my feed and return coolant hoses for the 1g oil cooler. MD163197 and MD167360. One runs between the alternator and turbo and the other is the short one on the bottom of the oil cooler. I haven't checked with a Mitsu dealer but parts vendors (Extreme, STM, RTM, etc.) are...

I have a coworker, whom I do not know very well, with similar hours and commute as mine. Every time I see her driving I cannot believe she hasn't crashed, lost her license, or worse. It scares me to the point that I'm seeking public advice.For example, if I happen to follow her out in the...

I'm curious if anyone has opinions or experience with either Enginetech or Evergreen pistons as an 1g OE replacement? I'm looking for a set for my 1g/6bolt turbo engine with stock fuel trims. I know there's other options out there like Topline, NPR/Nippon, and Silv-O-Lite. I've not heard good...

This is a 6 bolt 4g63, never been machined, 270k miles, stockish rebuild. As I understand with bore sizes (please correct me if I'm wrong), it's 85mm from factory and usually increments in .5mm (0.02in) when machined. I've seen piston sizes up to 1mm (0.04in) over size for stock replacement. My...

Does anyone have any information on the availability of 6 bolt ARP head studs or somewhere that has stock? Everywhere I look they are backordered with shipping dates all over the board. I don't need them for a couple more months but I'm a bit concerned I won't be able to find them in that timeframe.

I just need to vent for a moment. TL;DR at the bottom. This has nothing to do with cars, but rather mountain bikes. For the record, I live in a fairly low crime area.My son has an excellent opportunity to attend a technical school to fulfil his last two years of high school and graduate with...

I have an early 6bolt with original straight cut oil pump gears. Since those gears are discontinued, can I swap directly to the helical gears or do I have to replace the front case along with the gears?

I'm looking for some replacement piston options for my 6 bolt 4g63 turbo engine. Not looking for forged (unless the price is right) or anything with higher compression. Basically I'm going with a stock-ish rebuild. My current stock pistons have valve marks on them and I've considered fixing them...

Maybe I should be posting this in the noob forum because I'm definitely a noob when it comes to engine rebuild. But hopefully there will be some good info here anyway. Maybe this stuff has already been discussed but it's hard to search this site.I'm prepping my 6bolt turbo head, block, and...

Timing belt broke and I finally got the head off. All the pistons look about the same with valve marks. Are these pistons salvageable?

I'm redoing several electrical connectors in the engine bay on my 1g, like the injectors, knock sensor, coolant temp sensor, oil pressure sending unit, etc. I have to replace a few inches of the wire due to cracking insulation and sometimes broken copper. In the past I just used whatever wire I...

This is the Build Thread for 1991 TSi AWD. Reply below.

I'm looking for some opinions and maybe some first hand experience on performing a DIY head/bottom end assembly vs taking it to a shop. I don't want to put a lot of money into it, hence DIY, but I also don't want to have to tear it down multiple times to get it right. Time isn't much of a factor...

Whelp, got stranded on my way to work. It just died with no warning. No odd sounds and was running fine just before. When I crank it, it sounds like the attached video. Any ideas what's up? Seems like no compression or maybe just no ignition. I'll pull plugs and maybe the oil pan this weekend to...

Shouldn't the oil light be illuminated in this pic? This was taken right after turning the key to the on/run position but before cranking:

I used to order from RockAuto all the time for most my maintenance parts. A couple years ago something changed with how they calculate tax and now all I get is this message when I place an order: "We cannot ship to this address because it is in a "home rule" city that does not participate in...

When I start turning on power hungry accessories - blower, headlights, rear defroster, etc. - my idle becomes a little erratic. It idles a little lower and the engine runs a little rough. Sometimes when coming to a stop the engine stalls or barely catches in time when all the accessories are on...

On a 1g, does anyone know if the transmission breather is interchangeable with the transfer case breather?I see they are two different part numbers. I have a new transmission breather and I'm hoping it will work on the transfer case.

I'm about to undergo a transfer case rebuild (1g/5 speed). My drive gear splines are wore out and it's got over a quarter million miles on it. Nothing broken that I'm aware of. So a new (used) drive gear, all four taper bearings, seals (incl. the two large o-rings) and a new nut will go into...

Hello all, I'm new here but not to DSMs. Been daily driving my 91 Tsi AWD since 99. It's around 270k miles today. I lurked around CoDSM (Colorado DSM) until it inevitably went to the dark side. Looking forward to meeting some of you and sharing my many experiences with these cars.It's...
