Or use the higher compression pistons and tune for a lower boost.

go for it butters I was 2 parts away from my 944 n/a being an n/a -t. Then I bought a 951 That being said you can do it just like any other cars (like 240sx etc) that do it on the cheap. It's been done ( SCULAR on the boards has done it reliably and a few others..) and it will be done on the n/a I sold my friend.

When I say on the cheap I mean just turboing THAT engine. Using the same ideas that most anyone but p-car owners do.. You don't NEEED the turbo intake mani, looks like even the 951 xover bolts to the stock n/a headers, get an oil cooled only turbo, you can do run oil lines easily even on an early car.. use stock 951 intercooler, pipes are easy to make.. MSD BTM for timing retard/advance (or something more advanced like emanage, tec, smt, etc that can also do fuel) etc. I'm sure you know what to do

Sounds like you've really thought this out and have done your homework. Since it will be so simple, I say go for it.

Why not just start with a 944 turbo to begin with? There would be no benefit of making an NA turbo over a 951.

I dont think anyone here thinks that it CANT be done. It has been done. but a lot of the time, not cheap.
Most of these threads just end up in people telling each other it would usually be cheaper just to buy a 951.
Of course it's possible, and if you love YOUR car enough to turbo it, then do it. I know I would be happy with a turbo in my 944... but the thought of doing all that work makes me tired

Yes, turbo-ing an E30 BMW (or an E36 M3 woo!) is more interesting because you can't just go buy a turbo version of those cars for a couple grand more than an NA. In the case of the E30 there is actually some room under the hood too. In the case of the 944, you can just buy a 944 turbo and have better brakes, better wheels, a transmission that won't e-splode, an intercooler with ducting, and all the fabrication is already done. Considering it's only a couple-three thousand more for a 951 and you get all those benefits (plus resale/insurance value) it's an easy choice.

Turbo-ing an NA makes sense when:
You have a race car chassis with a ton of money in it and want more power
Your mom won't let you buy a Turbo but you can mod the NA in your friend's dad's shed
You want more power but have a weird sentimental attachment to your NA, and $5K-$10K means nothing to you.

Because I have a 924S and I like to be different. There is the uniqueness benefit of not getting a 951. I will admit, the 951 is a better car, but like I said, I don't want to be every other person with a 951 Plus, for a good condition 951 with only 50k miles like my 924S has, it would be much much more than to spend under $2k turboing my current car. Plus I bought the car for $2k + waterpump. So, there is no way I could come close to a 951 for less than a turbo project.

Don't want to be a wet blanket - but the money saved will be grossly outweighed by the money spent on the conversion.........

Not at all. But, it seems like most people here think so. Does everyone here pay for a shop to do there stuff or do they do it themselves? I do all my own work. It just takes time.

See my edited post above for price factors.

Go for it. Report back on how well it runs and how much you spent on it. Especially once you get to replace the tranny because you destroyed the ring and pinion, or stripped the 1st and 2nd gears off the input shaft.

Keep the nice 924s and buy a turbo, it'll be much better in all aspects.

Every time I think about taking my car a couple levels higher, I realize it would be better to buy another one and experiment than trash a nice car. To do otherwise could end in tragedy for sure.
