Why isn't there more turbo/supercharger conversions?

[PixelpeepS3]

Been playing around with the idea of scratching my Porsche itch for some time and the imminent sale of the other house means i have some money 'spare'

being sensible with it means i should only really spend £25k ish on the weekend car so i think ill try and squeeze a manual 981 boxster S with as low mileage as possible.

Coming from an all-weather capable 2016 S3 which hits 60 in 4.7 and the various remapping / hybrid turbo options a plenty if i was keeping it for any length of time the contrast from what i've seen is quite bleak for the boxster if i 'got bored' of the performance.

So the question - why isn't the internet overflowing with turbo/supercharger conversions like the MX-5, Civic type R and even the Audi R8 ?

is it really that tight with the mid-engine layout? is cooling the issue? would the gains be minimal ?

Lastly - what colour(s) should i avoid/look for ?

PARR did a turbo conversion on the 987 Cayman a while back, might be worth giving them a call if you like BOOST

Supercharger?

A supercharger is still 'boosting' the engine, it's still forcing more air in.

Buy or try one, then come back and tell us if you think it is/you are missing 100-150hp, I'm doubtful you will. If however you do, you'd be better off buying a 718 and remapping that, rather than wasting your money (imo) bolting a turbo or a supercharger onto a 981.
IF you're that much of horsepower junkie, I'd fit a 3.8 engine into a 981 and tune it, but don't think for one moment a big engined or forced induction 981 will be easy to sell come resale time, or that you'll get back ANY of the money you've "invested" in the conversion.

all the points you've raised are valid and ones i have considered.

i realise i won't make such sense but its because I've never had to consider a car as my 'forever' car.

I went for the 981 with the theory that its the last of the N/A boxster so value might hold a little better (i know doing any kind of mod will make this moot )
I also went this route because i want an event, i want an experience, but i also want creature comforts, reliability and something that the missus wouldn't look silly climbing out of.

I also enjoy straight line/off the line speed, the idea that i couldn't drop a reverse positioned cap wearing focus ST owner / joyrider would concern me.

i've only ever owned quick turbo cars, other than that my EP3 type-R was my last half decent performing N/A car - performance upgrades was only ever an ODB port away which could easily be reversed if it looked like affecting resale.

why i am i worried out resale if i'm planning on keeping it? i have no idea. my life is full of contradictions

It doesn't sound like the 981 is the car for you as there just isn't the tuning scene you're looking for.

it is half the car i'm looking for. The other half is an audi RS3 ?

[Twinfan]

Very different cars! A 718 is probably more up your street.

But thats just what i have now in a different skirt isn't it?

My itch for a decently powered n/a purpose built sports car that is reliable, won't shatter my spine and will look ok pulling up in a little village pub on a Sunday for a carvary seems to just keep coming back to the 981.

I think i am trying to get a car to do everything which isn't possible. Life is a compromise right?

I haven't driven the 981 boxster S - i know it'll be the right car - the noise, the experience and it still has 315hp and doesn't weigh much.

Right, i'm back on track, i'll 'make do' with the performance lol.

There was a time when you would find loads of turbo modded cars at track days. All sorts including GTR's with silly outputs. One thing you could pretty much guarentee was that a lot would be going home on a trailer having shat their oil or water all over the circuit or paddock.

There's no substitue for CC's. I'd keep a flat 6 NA and enjoy it as it was

911 & Porsche World liked this 987.1 Boxster S with the Parr fitted TPC Racing turbo conversion.

TPC have this kit for the 981.

His sir considered the TTRS ? I suspect it would be right up his street, it will out drag pretty much anything in a straight line, utterly dull handling, requires nothing whatsoever in the way of skill to pedal hugely fast, completely lacking in any degree of tactility or engagement (sounds nice for the first few days, then the whole thing becomes so utterly boring, even the tuneful engine/exhaust loses its appeal)
450hp is but a map, fuel pump, downpipe and intercooler away....

Obviously everyone will think you're hairdresser, but you can't have everything ...

[Porsche911R]

I ran a TTRS and my mate runs one now great little cars for off the line and turbo performance and sound the nuts.

Great daily and will kill just about any thing off the line. I used to vmax mine all the time :-)

bloody great engine.

So did I
It was a Plus too. May as well have taken the train, it’d have been a more engaging, fun experience.
A great engine in hopeless chassis with frankly pathetic transmission, let’s not mention the brakes and seats ...

All the proof you need that outright speed means nowt if the chassis beneath you is hopeless.

sounds much like the RS3 I drove around Portimao circuit. Awful thing

As always I added squat, big ARB and 430 BHP, intercoolers and solid engine mounts, the OP wants off the line and straight line performance, nothing better at this price point imo. and forget 4 pots, no torque, I had 430Lbft Torque at 2k revs ;-)

Might as well have been 4300 Torques,
Describe the handling characteristics. Actually don’t, I’ll do it for you...

Driven gently : Mild understeer.

Driven spiritedly : Understeer.

Driven as it’s maker intended : Terminal understeer.

Haldex ? I’ll take a proper front wheel drive car over a Haldex equipped car ANy day of the week.

For someone who bangs on about hating understeer David, you’re giving a lot of praise to a car renowned (even in its latest, light block 400hp version) for being utterly dull (and understeery) to drive (from a handling dynamics perspective)

I’d take an M2 or a 718 S EVERY time.
