Thanks for all the help

I will drive more the car to see if it adapts. Unfortunately, its still snowing here in montreal.

Steve wong also told me that we can bump the icv a little? Anyone did that??

I have a '98 with LWFW and have never stalled in normal driving (not to rub it in to OP). I wouldn't call the '95 cars flawed, they just are not an ideal candidate for a LWFW without accommodations being made. Luckily, '95s are easier to modify with chips and whatnot and '95 owners don't have to deal with OBDII, so there are pros and cons to that one.

I think Porsche used a DMFW because it's more refined and civilized. The LWFW revs quicker and the car is more raw and reactive. It's a little louder and a more aggressive feeling and perfect for heel/toe. It really changes the car's personality. I personally love it, but it's a pure sports car thing and it doesn't fit the slightly more mature personality baked into the 993.

Paseb - for what it's worth, I let my car idle for 10 minutes without touching it (after battery disconnect for 30 min) before I took it for a drive and never had an issue. Not sure if the chips acclimate the idle or not on the '95s.

edit: I also installed a new ISV and I had vacuum lines inspected and some of the elbows replaced.

Seb, as mentioned, taking out and cleaning the ISV valve usually cures the issue. If not, others have stated that a new ISV valve was sure-fire solution.

To the op, after a couple more drives, the change in pedal behavior becomes second nature. Its part of the 993 enthusiast experience.

Having said that, I don’t think lwfw is an especially friendly street car modification. Sounds like a bag of bolts.

I keep hearing that complaint but I hardly ever hear anything objectionable. Just sounds mechanical. Of course I have a Fister III exhaust, so my car is already rude and mechanical noises are just part of the experience.

+1. Bag of bolts sound comes from changing the trans mount to a solid metal version.

Bug is the wrong word. A 95 993 peculiarity in that the other years seem to handle it better.

Even with a regular mount it is a bit rattly. Different trans fluid helps that too.

The main issue is that the LWF (with it's lower mass) would not stall with a higher idle. But for street driving, a high idle it's not optimum... So when we modify the car its difficult to achieve the best of both worlds: low reciprocating mass for quick spool ups and a low idle for quiet waits at stop signs.. It's not the car's fault, it's our fault for messing with the 993 and wanting it all. If you have ever heard a cup-car idle, then you'll know the meaning of "coffee can full of bolts" ..

How does the mid weight flywheel (MWFW) compare- anyone have any experience of that?

Spools quicker than a DMFW but not as many rattles as a LWFW.

​​​​​​Yep - only ever had stock trans mounts but have had the can-o-bolts serenade for all 50k+ miles of LWFW. Delvac is quiter than PTX, but PTX shifts much more nicely.

This. The need to adjust driving styles is by far outweighed by how much more fun the car is to drive for me. My car is highly modified and used in anger only on weekends. I would not want the same experience for a daily driver.

I daily drive mine three seasons. I like the all-encompassing experience, which is one reason I bought the car. The noise of Fister III exhaust largely masks any lwf noise, although I can sometimes detect a faint, Duccati-like clatter with clutch out at idle. I like Ducati’s and the sound they make so it doesn’t bother me. Blipping the throttle isn’t hard, and has become part of the experience driving my specific car. I don’t personally consider it a defect, but do understand exactly what pp000830 is saying. I won’t make any claims regarding real or perceived performance gains either. I have driven a beautiful, low mileage 100% stock 993 and while it is what Porsche intended the 993 to to be and objectively a nicer car in every way, I much prefer the raw experience mine provides.

As a side note, when my 15 year old daughter drives the 993 she does not blip the throttle and it almost never dies, so technique may be a component. Seems like the higher the RPM is when load is removed, the more likely it is to drop to zero before the chip can do its thing and save the day.

I've heard that is what Singer uses

The mid weight flywheel and clutch kit is available here: https://www.ebay.com/itm/223441142395?ul_noapp=true

Seller states that it is specifically designed to prevent stalling on early 94-95 OBD1 cars.
