turbo setup on a NA

[will944]

Alright.....I already know that if I'm looking for serious power buy a 944T!!

But I'm thinking about just screwing around and adding a turbo to my NA for some "free" horsepower. I was thinking about a supercharger kit....but don't like the fact that it has to run off a belt. Any power loss is fairly substantial in a 944 as we all know.

So, my question is whether it is feasible to buy 944T headers, x-over pipe, downpipe, turbo, intercooler, etc etc and bolting it up to my 87 NA. Just curious about the fit....would the headers mount to my head?? Clearly custom piping would be made for the parts.

I know low pressure would be required due to the high compression....I was only looking to push around 6lbs. Add some Turbo injectors and an adjustable regulator to work the air/fuel ratio.

Is this possible???

Jesus christ, didn't we just discuss this like 2 days ago??? DO A SEARCH!!!

[will944]

hmmm....thank you gearhead290......great input!!

I haven't seen much in the past week about anything but putting a "S" head on an NA block, and some talk about a guy supercharging his NA, oh....and some info about an RX7 or something.....

I don't eat, drink, and sleep the forum....must have overlooked the thread about bolting a turbo to an NA.....

will944, yes you can turbo an N/A. You can turbo practically anything! Most people here say "sell N/A, buy a 951" that doesn't mean an N/A can't be turboed. What it means is unless you are going to do ALL the work yourself, and have an excellent working knowledge of turbo installation and tuning, it may be cheaper in the long run to buy a car with factory turbo set-up. If you have a good knowledge of what you are doing and have access to fabrication equipment, you can turbo your N/A fairly cheap and have substantial power gains. You will most likely never get an N/A on pump gasoline to the same power level as a stock 951. I say go for it!! Many people ask and talk about doing it but never actually follow through. If you are fabricating the 'kit' yourself you can use readily available non-porsche parts and save alot!
just my opinion though........

[gearhead290]

will944-I did it for you i think I might do it.....

And wolf1-how cheap is cheap? I would be VERY VERY surprised if you can do it for under $1500

[Wolf1]

Gearhead290-You could build a turbo set-up on an N/A for $1500.00. And when your talking about blowers, turbo's and horse power, that is fairly cheap.

[will944]

That is pretty cheap. My family owns a machine shop, so accessing things of that kind is not much of a problem.

My only concern at this point is if the turbo headers would mount to the 87 NA head????

Thanks

[overkill]

Buy a turbo. God I hate this question. Over and over and over and over.

From what I have heard, Yes.

[will944]

I agree overkill! You can get a ****load more power from a 944T.

My odometer stopped....so a sale for all I've put into the car isn't worth it. I was just thinking about screwing around and bolting up a turbo. I start my job June 2nd....we'll see how the finances go.....

If I had the money I would prove that statement incorrect.

Yes, the turbo header will work on the n/a head, but I don't reccomend doing this. You will also need some heatsheilding in different places. IMO this is a waste of time and there are much better ways of spending your money.

I want to know what this $1500 kit consists of, something tells me that you left something out.

[highboost951]

"Yes, the turbo header will work on the n/a head, but I don't reccomend doing this." Why is that?

What do you mean by that?

Gearhead, I don't understand you bud. What do you have in mind or why don't you think you could do it for $1,500?

944 turbo exhaust manifold: $250
944 turbo computers: $350
engine wiring harness: $100
Fuel injectors: $100
turbo: $250
turbo engine mount: $50
crossover pipe: $150
Intake manifold: $100
wastegate: $75
catalytic convertor section: $150
downpipe $50
airflow meter and box: $100
intercooler: $200
intercooler pipes: $50

total: $1,950 Now don't you think with some shopping around you could get all the above for a little less, like less than $1,500?

[highboost951]

"IMO this is a waste of time and there are much better ways of spending your money." are you just grumpy because you car is dead right now? You're just coming across a little negative today

[gearhead290]

Are the n/a heads and the turbo heads BASICALLY the same, correct? I know that there are differences, but aren't the layouts the same?

When I said "if I had the money" I meant that I would show him how you the n/a has the same potential as the turbo engine in the right hands.

Highboost, if you're going to turbo the n/a motor wouldn't you kinda want a good set of low compression pistons? IMO a 10.2:1 compression is just a bit high. AND the prices you listed seemed a little low on some things from what I've SEEN them go for, granted I don't look at a lot of OEM part sales.

are you just grumpy because you car is dead right now?

Yes, actually I am. The drift gods are laughing at me

[1.2gees]

I would sit down here and argue the point, but I don't know how I'd make myself feel not stupid after doing that since I've done it at least 3 times, in the not too distant past. Do a search.

Now for my 3001th post here's what I'll say:

DO IT! PLEASE, document your progress (failure?)as well will you?

"Are the n/a heads and the turbo heads BASICALLY the same, correct? I know that there are differences, but aren't the layouts the same?"

Yes they are, I was just asking why you wouldn't recommend doing this in regards to fitting the turbo header to the n/a head.

"When I said "if I had the money" I meant that I would show him how you the n/a has the same potential as the turbo engine in the right hands." How would you accomplish this? Supercharger right?

"Highboost, if you're going to turbo the n/a motor wouldn't you kinda want a good set of low compression pistons? IMO a 10.2:1 compression is just a bit high." Yes but he's only running 6#'s, pretty much the same as bolting on a supercharger only running 6#'s on high compression pistons. His will actually be 9.5 : 1, not 10.2 that's on the '88.

[gearhead290]

I just don't reccomend the swap.

I would swap in the 968 and turbo that.

10.2:1 compression started with the 97. http://www.dimmer.net/hosted/944central/lna/specs.asp And if you were to turbo it right you would put in lower compression.

[highboost951]

"10.2:1 compression started with the 97" I know you meant '87, but from experience it started in the '88 models. The higher compression pistons were introduced into production in '87 but for '88 cars. This is why the dme's didn't change until '88. I agree to do it right he'd need to lower the compression, we had the same discussion regarding the supercharger guy. If you want some serious power out of an n/a w/o turbocharging it, it will have to have the compression dropped w/ turbo pistons and juiced by a supercharger running 15PSI. But, this isn't what he's after, the same w/ the supercharger guy. Like Ahmet, I hesitate to reply to these posts and this is why I waited as long as I did. I just don't want the guy to be mislead.
Oh BTW: easy on the guy, he's a newbie. I think you've asked or a said a few sillys yourself as we all have. "Jesus christ....DO A SEARCH!!!"

[highboost951]

"I would swap in the 968 and turbo that."

Got some deep pockets eh? I don't think this is what he wants, we all could have said "just buy a turbo", I think you need to talk to D993, hehe.

[gearhead290]

I do recall somebody's signature saying "stupid is as stupid does." This phrase applies to me.

I'm just sick of reading about this, and everytime it's asked it just adds one more thread to click on when somebody actually does a search.
