I'm about to replace all the timing-"associated" parts on my '92 Talon TSi AWD, e.g. TB, BB, pulleys, tensioner, WP, seals, belts, thermostat, etc., and realized that it's probably time to replace the harmonic balancer as well. It was replaced after the original one failed just over 18 years...

No check engine light or code starts is ok for legit a second or two then idles rough and stalls not sure what is going on. Recalibration wideband.

I’m finding good intercoolers, but hardly anything sold with piping, much less GOOD piping. Any recommendations?

Hello Everybody,I recently purchased a 1998 Mitsubishi Eclipse GST, all stock, the body is in great condition, has everything except an Engine and Transmission. Before you call me dumb, here is a little story. My grandma used to own a GST, she bought it from new and had it for some years, then...

Hello ya'll, kinda new to the DSM world but I learned so much lurking these couple months. I recently bought a 1G Mitsu eclipse, 100.000km (62.000 miles) in good shape, practically stock, GS (European trim, 150hp), LPG conversion kit installed and working.Everything is fine, the only issue I'm...

New here lol bare with me I need guidance …Hello all, I recently bought a 4g63 n/t (didn’t know) it was n/t my goal here was to build a motor in my garage and source out a shell along the way, so as I get into my new 6bolt I quickly see I don’t have oil drains etc after checking the seria...

I have a question and it might sound dumb but I couldn’t find any info about it. I have a 7 bolt 4g63 for my 2g eclipse that I’m currently rebuilding.A couple days ago I rotated the crank until all 4 pistons were even across. I filled each cylinder with oil. When I went back to look, the oil...

So just recently I have started having issues with my transmission. When the car is off shifting is smooth, when the car is idling it's very hard to get it into any gear, once you get it into gear you can hear some chatter/metal rotating on metal noise, this goes away once you start driving...

Hey! My name is Jaime bravo & I’m from the Pacific North West. My 95 gst and I met 4 years ago when I bought it at 15. We had some great times but I Traded it for an s14 240sx it at 17 but recently bought it back as a shell at 19 years old. This time, I’m not a broke 15 year old with a weekend...

I have a 2.4l fwd automatic trans convertible 3g eclipse w/ the 4g64 sohc. So I want to install a 4g63 head dohc stroker but don’t have any experience wrenching so for starters I want to know if I need to buy the heads off an auto fwd or can it be from a mt? And as I believe mine is a 7 bolt I...

So I deleted my ac out because it didn’t work anyways in my 98 eclipse gst what size belt would I use since I don’t have the ac pulley or the tensioner for it

Hello everyone. As we all know, these are trying times, especially for the small business owners. With that, I have been developing, with the help of several DSMers from around the world, a list of DSM supporting vendors. With this I am hoping that when yall need to order some parts, you think...

Recently replaced the head gasket & rebuilt the head of a 4g63 NT '94 Talon. Replaced the IACV as the last one was measuring out of spec (actually, just shorted the entire thing), with a used one off eBay and it has been significantly better.The one thing I can't figure out, is why it idle...

So, I have this snag in my swap process. I am pretty sure that my transmission is stuck in limp mode. It was never separated from the motor and worked fine prior to the swap. Seems likely that it will be a wiring issue but we all know mysterious shit just plagues DSM life.I am curious...

Hello everyone, I just bought an eagle talon tsi awd automatic from my brother, I previously had a 1g tsi but due to fate and this pandemic I had to sell it and my brother agreed to sell me one of his dsm awd since he has others but this car has never used it I bought it about 10 years ago and...

Okay, it’s finally time to say goodbye. Due to financial reason of being laid of due to covid I have to part ways with my baby. She’s been with my uncle in Arizona for a while but with everything going on it’s time to let her go.Bone stock 97 GS-T Spyder with 76,000 miles. Yea, you read that...

I am rebuilding a 1991 4g63t and when i took the head of i saw that the pistons had valve marks and i believe the timing belt snapped when the previous owner had the car which lead to the valves hitting the pistons and cause the marks, is it ok to use these pistons with new piston rings or...

So my closed loop operates fine but I currently have open loop locked because it seems to be more consistent and I want to focus on WOT. I just fixed a huge boost leak where the motor mount had worn a hole in my j pipe and the car hauls ass, however I am still seeing a ton of knock and its...

My DSMLINK v3 is out for delivery right now, it is a used unit. I have done some reading and gathered that I should Download a stock file configuration and or make sure all sliders are set to 0 and I adjust for my injector size.I've recently did maintenance such as head gasket, timing...

Hello everyone! I will skip the storys and get to the point (if you want 'em, let me know). I posted this on DMStalk, now here to increase my feedback chance:I got a 93' Eclipse 2.0L 4G63 DOHC N/A 152.000 KM and after sitting for about 3 years it has the following issues: 1. rough idle: RPM...

So I'm in the process of pulling the motor/trans in my 2g awd. While removing the electrical clips I pulled the injectors. I had just cleaned the whole engine bay in the beginning of summer. Though, when I pulled the fuel rail I noticed it was dirty around the injectors. Sand could have fell in...

Ok so I have all of my timing marks aligned correctly. I am trying to install the belt but it does not have enough slack, I have the tensioner pulley completely lose and the grenade pin still inserted in the auto tensioner. I followed the vfaq for correct routing and that does not work. All my...

Just got my new seals and valves installed, got water sitting on the valves to see if any leaks exists. After that I'll install the BC268/272 cams shafts and cam gears. Everything went smooth and I used the K-motors compressor tool, it was only $50.

So I think to get the experience I am just going to go ahead and rebuild my head myself. I'm not looking to do anything fancy, my car is around 320WHP and I only need to replace my exhaust valves but I figure while it's all out what are other things that should be done.Also if you could...

Trying to get my intake manifold off but I have no idea how I am suppose to access the lower bolts... I have tried with everything that I have to get a socket or wrench on there. The design is dumb it has the bolts positioned right under the runners I can barely squeeze my arm under there with a...

When installing the timing belt with the Kiggly racing tone wheel and AEM cam gears I have lined up the marks on the cam gears and held them in place with the STM cam gear holder. I have lined up the mark on the tone wheel (crank gear/kiggly tone wheel) as accurately as possible (the balance...

So my 95 eclipse GSX has had engine cutout on and off recently while on the road, and now it wont start at all. No spark, no fuel. My research suggests to check the Cam angle sensor (Cam), then the Crank Position sensor, then finally send the AEM engine management system (ems) back to be...

Curious on where to install a fuel pressure gauge on a 2g when using the stock fpr it bolts directly to the fuel rail so no way to put my T barb with my sending unit in between.

Here is a link to their website. I have contacted English Racing but they no longer offer Black Box tuning for our cars. Claiming that they always come in bricked, even after confirming with them that mine is not bricked and I have been making adjustments myself they have not responded at all...

Going to be swapping from my 450cc to 680cc injectors today and I am curious on the latency values. Do I just add to my current values the recommended amount for the 680cc?

So I have the opportunity to get some 560cc evo8 injectors local for $100 maybe less depending on some feedback from you guys. I've been looking around for some 650-850cc injectors and just can't find any for a fair price. I'm almost at the point of just buying brand new.I noticed one of the...

So finally got my cruising AFR up to around 13 and out of no where a day later they just went to 11 and it wants to stay there. My Idle and WOT did not change at all so it has me confused. Any ideas on what could change cruising AFR but not change the WOT and idle?

Out of these two which do you guys prefer?You must be registered to see element. You must be registered to see element.Also a side question.. If you had the option for 850cc, 660cc, or 560cc injectors for my Small 16g, 2.3l with a FMIC at 15-18 PSI should I just go for the larger ones?

Injector latency varies per injector and is suppose to adjust idle AFR. Does increasing latency give more or less fuel though?

So still tinkering with my tune to get AFR set perfect. I have seem to get idle to be near perfect it still shows a little rich after pulling up to a stop light around 12.5 then eventually comes back to around 14.However when I let the car idle for 16+ minutes my fuel trims never changed, I...

Just got a sensor installed and my wideband gauge hooked up. At idle the car sits around 13.5 then cruising it's really rich at around 10.3-10.5. When I come up to a light and idle it's around 11.7 idle however once the car sits idle for a while it will go to 13.5. WOT it pegs at 10.0 and I...

So going over all the vacuum lines and replacing any bad ones on my car and I noticed this has some hoses missing from it. I don't know exactly where they all go to but it seems to be half assed removed. Can I get rid of it completely or what are some issues I may have?

When purchasing link v3 it's kind of unclear on their website if it comes with a ecu with it installed or if you have to supply an ecu. I have my stock ecu but it isn't eprom. What are the cost I'd be looking at for full v3 with the ecu?
