Having done a search I find a lot of guys out there installing the TPC kit. But I'm still not finding anyone with an SoK kit on a 95 993. Anyone out there? If so let me know what you think. I have sent and recieved their lit. But would like to get an opinion from someone who has jumped in.

 

You will spend $20K before everything is said and done. For that kind of coin, might be better off trading up to a TT.

 

If I had a 5 spot for every time I heard that, I could probably afford to upgrade to a turbo. See My previous post on a related thread below:
The SoK kit does require an engine disassembly to do the headwork (lower compression) and the addition of a new heavy duty clutch assembly to handle the new power. They even include a software system to custom tune your set up for different driving applications (stoplight to stoplight, open road, etc.) When I recently priced it the total job including clutch package was about $18K. But here's how I look at it. If I were to sell my 95 I could reasonably expect to get maybe $30 to 34K. Add the cost of the Sok kit at 18K and I still would have to kick in at least another 10K to get a decent TT. Although I've never driven a SC'ed car I sure like the numbers- at least 50HP more than a 98 Turbo "S" (last I looked they were past the 100K price.) and the idea of instant power. I should add that my car only has 44K miles on it so it's got a lot of life yet and should handle it. Also I only drive my car as a weekend or pleasure cruiser despite the assurances from SoK that it is a very easy set up to live with on a daily basis.

As also previously mentioned after five years of ownership, I have a lot of extras in my car that mean a lot to me but would be pretty much a wash during the sale of the car. You know how it is , you get to know your car and you feel comfortable with what you have.

 

Add the aux oil cooler and you are at $20K. Once you add the go, you've got to add the stop and brake kids will also add to your bill. Plus, how reliable is the SOK kit?

I also looked at the kit and got their info when I had my C4S. I decided the best decision for me was to upgrade. Plus, I am now a 100 HP over the Turbo S!

 

The black brakes should be fine for the street. I've had no fade yet. Sounds like you have a killer car. But if you went to a TT AND almost 525 HP were not talking upgrades were talking second mortgage.

 

Good point!

 

I searched around for SoK a few months ago and came up with zip. Not surprising, since its basically uneconomical compared to a TT (sorry, but I really believe that). I suspect that VERY few people have gone the SoK route. Ask them for references!

 

The other eric: You're probaly right. Not many have since I can't seem to find ONE! I still believe it's a viable alternative. The guy I spoke to there seemed pretty knowledgeable and claimed they ( SoK) had a 964 race car that had over 24k miles on it and no problems. It all looks impressive but as you stated they're probably between a rock and a hard place. Most guys just kick up to a TT or go with the (much less expensive)TPC kit. As I said I like my car. I have it pretty much the way I want it cosmetically. If I could just find that extra HP and more importantly torque. I'll throw this out there --What about gearing? I have virtually no use for 6th and the dyno showed me that there's room between 1st and 2nd (too big a drop off for my tastes) Anybody??

I like SC very much and I will eventually go that route in some project sooner or later. However, if you want to look at it from a financial POV, your best bet would be to purchase a TT engine and sell your N/A, short of buying a TT car. Don't think about resale value as numbers won't be matching of course. You can get a good TT engine for $15-$18k, or $20-$22k with all sorts of mods on it taking you to 520+ hp including clutch, LWF and PP. Sell your N/A engine and get used TT brakes and an extra oil cooler or have a home made one DIY (do a search here)
As far as gearbox is concerned, changing 1st and 2nd gears will be costly, I assume you have the G50/20 box, if you are upgrading the engine KEEP it untouched! You will need taller 1st and second gears believe me, OTOH it is expensive to replace the first two gears.. You can shorten 3rd to 6th.

 

Jean: The only problem I have is I have driven a turbo car. Not the TT but an earlier one and I just don't like the "feel" of the turbo. Maybe the TT is a different animal and I should get some seat time. I would kick up to the 98 Turbo "S"(425 HP) in a minute and sell my car if I had an extra 70K lyin' around. Believe me I'd GET use to it. My previous 911 was a 77 3.0 Carrera (euro). It was NA, Webbers, twin plug, RSR pistons, etc. I loved that car and frankly it seems that the 993 is not as quick as that '77. That car was an animal (totaled by a 16yr old who ran a red light). But I'm straying here. I was thinking more in line with a new ring and pinion set to achieve a little more umph. But as I have learned in the past there truely is no substitute for power. Gears, cams, etc. just seem to push the power around from here to there.

I have owned among others a 3.6 turbo 964 until recently with 460 hp, 4WD, 6 gears, etc.. and it is not the same as a TT. It was a beast but nothing below 4K RPMs. A TT with very light mods will push very hard starting 2500RPMs. The TT engine is stronger than the N/A as well. Value for money, you cannot beat the swap. Other than that, it is personal taste.

 

That's encouraging. Because I kind of feel the 993 power curve is all wrong to me. It took me a while to get used to driving it at 4000RPM. It's the same for me as it was with your 964 Turbo --Nothing below 4k RPM. The '77 Carrera pulled hard from 2500 all the way to 7200. And I mean real hard. Of course the '77 was a lighter car but I really think the power on at 2500 RPM feels right to me and my style of driving.

 

901 aero,

these guys in the UK - Autofarm - 911 specialist, have built one, its for sale on their website, so I guess they have experience and knowledge, it might be worth asking them for their views, the owner is Josh Sadler, a guru on early 911's in the UK

good luck

P.S. I know what you mean about keeping the car, I am in the same situation with my 993 whcih has many mods - manily brakes and suspension, and I love it, but want more power for the track, i had looked at the TPC kit but it is not recommended for the track - so still searching for a decent power upgrade or thinking about biting the bullet and going for a GT3, but it doesn't look anynear as nice as the 993.

 

I know Autofarm, they built my previous engine, the guys are great but why pay $17k for a supercharged 993N/A engine when you can pay the same for an original turbocharged engine that has factory reliability proven? As I said earlier, the TT engine has several upgrades done to it that you are not getting with a N/A engine, rods, heads, cooling etc.. You can also get another 50 hp for very little investment..
