POV How to Make a 400HP Boxster | Overview & Drive

[@tomkingslayer8375]

you're slowly convincing me to make a poor financial decision

[@nabslp670]

It'll hold its value better than a regular car, not too bad of a move

[@DasCayman]

I ended up timing the bond / interest rate market back in 2020 and I bought this car with 18k miles on it for $50k… at its height it was worth maybe $90k in 2023. But I’ve passed the point of “collector miles” and just want to enjoy this thing everyday to its and my dying breath, bouncing off the rev limiter, sideways.

The instant nature of the revs is what does it for me. Is like a racecar on the street. And it’s astonishing that it doesn’t take much ultimately. Everyone defaults to 911, this is a great example of how good the Spyder platform is.

Having driven a Cayman of this generation, I can say with 100% confidence it was 70% the fun as my GT3. Id imagine with these mods it’s probably closer to 90% for a fraction of the cost. Love it

[@chriskilgore2521]

@@sdlausen1the gas powered Boxster and Cayman is going away after this generation. The Spyder was very limited production for each gen but especially in the 987 gen, only gen to get a hydraulic steering rack as well. I’d say it’s at least as special as the S2000 CR. Having owned an S2000 AP1, and now a 987 Cayman S, the Porsche is a much different car, and can handle a lot more out of the box without modification, when you start modifying them they really become fun. My S2000 was stock and many years ago. I went Miata, S2000, E46 M3 FBO, E92 M3 (supercharged) M6 V10, MazdaSpeed 3 (FBO), another E92 M3 (stock), CLS55 AMG, and now Cayman S. I’ve owned the Cayman S longest, and modified it (coilovers, exhaust, headers, IPD intake plenum, GT3 throttle body, tune, and short shifter) and go on long periods of time where I don’t drive it, then start toying with the idea of selling it. Every time I get to that point I drive it, and don’t want to sell it, most fun car I have ever owned.

Hey boxster fam! I have a 981 boxster GTS with stage 2 Cobb tune and a fab speed headers. Makes about 450 hp to the rear wheels. I’m biased but one of the best sports driving experiences you can have. I will say with the six speed manual. The clutch starts the slip when you really beat on it. Stock clutches probably starts to fade around the 430ish mark

[@DasCayman]

I've said if you could just have one Porsche in the garage, 981 GTS Boxster manual is an amazing option. You get all the modern interior and tech and still a good raw performance. Hardest part about the Boxster GTS manual is.....finding one for sale! There's usually no more than 1 or 2 for sale nationwide in the USA with a manual. Congrats on that!

[@apancher]

450whp? Have a dyno video? That sounds...impressive

[@TexasRiverRat31254]

Life with a Cayman is very good! I'd love to do an exhaust on my 987.1 but I'd need the whole system which is just a bit much right now. If my 80,000 mile service doesn't uncover any expensive needs it could happen. Thanks for the help with discounts! Every bit helps is true for sure.

I've driven a stock version of your identical car, and it definitely didn't feel underpowered. Adding another 50+ HP to it must be bonkers. I'd still take it over a 718 spyder though cause that 987 is just so raw.

[@williammorris3334]

Soul Performance working with Softronics Tuning has maxed out the 9A1 engine with bolt on mods. The intake adds little to nothing. Full exhaust with stage two tune yields 360-370 hp. Only thing after that is more aggressive camshafts which basically ruin the bottom end of the power curve. Frankly spending this amount of money on a 987 is too me a waste. You’re looking at least $100,000 investment for the car and these mods. For that amount of cash you can get a 981 Spyder with the 3.8L engine from the 991 911S. The 981 Spyder makes about 430HP with a tune and headers. You’ll also still have a car that can be returned to stock easily and won’t depreciate except for the miles you put on it.

[@DasCayman]

981 Spyder is a really nice one Porsche solution imo. Modern tech and interior but still a decent raw grunt

[@youmongrel]

I’m really tempted by the Boxster, but I want my next convertible to be one we can road trip and see the country with my wife. Unfortunately while the storage is decent, there’s no reclining possible to even take a nap over long distances and I just don’t think it’s going to fly.

I love and trust these tires with my life. Outside of those I'd also recommend Bridgestone Potenza Sport's. Bridgestone brought me out to one of their autocross events and I was able to use and abuse their M340i's on those tires. If you have the money and the car for it those are the tires to go for. They're also pretty even in the comfort level as well. I use the Nfera's literally every singe day of my life.

Hello, you are also singlehandedly slowly convincing me to pick one of these up. I’m currently looking at one that doesn’t have the sport chrono option. I had a 987.2 2.7L Cayman back in the day with sport chrono which gave the ‘sport’ button in the interior. I remember the throttle response becoming WAY more responsive after pushing that button. I later had a 987 without chrono and I really felt it lacked that sport mode. However I will be ecu tuning the Spyder just like you. Can I tune in the sport mode throttle response and benefits the sport chrono option gives, without physically having the chrono option?

Hey Das! I own a Cayman S 987.2. I al ready have a GT3 throttle Body and a IPD Plenum, air filter, and headers with a custom tune which roughly gives mi 345 hp (320 is stock). I was asking myself if I could install the dundon runner intake, however I have read that with all the stuff I al ready have the runner intake will be pointless, to much air flowing wont make better results. I am hesitant about making that upgrade and making a new tune to adjust the intake runner. Hope to hear back from you soon! cheers.

Hey! I think I got back to you already on IG, but incase others have the same question I'll post it here too. I would not do the Dundon intakes after you have what is already on the car. You'll have too much intake compared to the displacement of the engine. If you did add the intake runners I believe the improvements would be very small and not worth the labor and $4k for the parts and another $1k on the tune.

That GT4 had the full $20k Dundon kit on it. Also the extra ~1k rpm helps the GT4 stay in gear a little longer. It’s also a 3.8L and I didn’t have my dyno tune or intake runners at the time. Nevertheless, you wouldn’t notice on backroads. My friends and I (even with the new RS’s) all say that all these Porsches are the same speed

[@BFCOT]

That makes more sense now. Interesting feedback on the Cup 2, I was going to order 245 and 285 for my Spyder. How much playfulness has the car lost?

[@DasCayman]

@@BFCOT the playfulness will eventually come back once the tires wear in and lose that peak chemical bond structure with the pavement. A worn in cup2 is my favorite tire. 60-70% of the grip as a fresh one and extremely responsive. I think we just gotta do a couple track days to wear them in initially :)

I'll share a bit of information on the MA1/9A1 engine series with you. The 2.9 (987.2) & the 2.7 (981) share the same engine cases and bore dimension, but the stroke is different between the 2 engines. The 3.4 (987.2) & the 3.6 (997.2) share the same engine cases and bore dimension, but the stroke is different between the 2 engines. The 911 3.8 (997.2) & (981) GT4 share the same block and it's base off of the 911 Carrera S; it also share the crankshaft (77.5 mm) with the 3.4 engine. How you get the 4.0 is by installing the 3.6 (81.5 mm) crankshaft into a 3.8 engine. I have a modified 2010 Cayman S and have made all the changes he's done on the Spyder, with some minor parts differences, except for the Dundon intake runners and I have 323 to the ground vs 320 @ the flywheel (stock) which equals 372 now @ the flywheel. Hope this helps you out. Long live Mezger Junior.
