944 potential

I am thinking about getting a 944. I would obviously want to get a 944 Turbo, or an 944 S2, but I do not think that it is in my budget. I have to aim for the 944. I was wondering what type of modifications can be done to the 944. I understand that putting a turbo in is too expensive and that I should just buy a 944 turbo. But is there anything to boost the power on the 944? If there is what type of horse power does the modification add? I am not looking to go out drag racing, but I would like to know that if I get a 944, I can get a little more power out of it.

on all non-turbo 944's there are a supercharger kit that some 944 tuners sell but its in the price of $5,000+ You can have a none turbo motor converter into a turbo but its very expensive and still wouldnt perform all around like a real 951. only the 944 S2 i can see worth putting that much money into converting into turbo because the body & suspension are very simular to the turbo model but again probably be cheaper to just get the supercharger kit.

What im planning on doing w/ my 951 sooner or later when i have the funds to do so is bore & stroke it to 2.8L or 2.9L so i will have the low end grunt of the S2 w/ the high rpm pull of the turbo. Just depends on what you want to do with the car. what are your tastes and what your funds allow.

I prefer the looks of the S2 & Turbo over the 944 myself. I used to own a 83 944 and was great when i first got it but i knew i wanted a 951 sooner or later but i got the regualr 944 to get a feel for what these cars where like then i had enough money for a 951 and i switched over.

It was hard choosing between S2 & 951 cause both are great cars. I like the S2 because of it having good power at all RPMS but i also loved turbo cars since i was a kid am my parents owned a Plymouth Sundance Turbo. To me as a kid it was fast and loved when my dad mashed the throttle and the boost gauges start moving. Thats all i did anytime i was in that car i watched the boost gauges.

I finally chose the 951 because i can always go bigger displacement and i also like the fact the S2 had a 16V DOHC head but the heads can be swapped with alterations. Good thing about S2 head also is since there is no ceramic exhasut port lining you can really port the ports. lol Although i wish there was away to have the exhaust port relined with ceramic afterwards. Only one can dream.

There really isnt end to a 944's potential. as long as you have enough money there is more potential. When i had my 83 944 only thing i ever did to it was chip, throttle cam, & tires to me since i wasnt planning of owning the car for along time it wasnt worth putting alot of mod money into just maintained it.

for N/A 944 - cone filter, MAF, throttle body, stroke to 2.8 L, port/polish and valve job, fuel pressure reg, pistons and rods - for higher compression and possibly higher redline, chip (or independant engine management), headers, exhaust, lighten the flywheel and crank shaft, cam grind, after all that you'd probably want new injectors.....with all that you might be able to get an extra 40 hp to the wheels....then you could lighten the car...fiberglass body, lexan windows....you'd also get alot just by upgrading the suspension/brakes.....and we all know that a nice system with maybe a pair of downfire 10" subs make a car go much faster lol!

oh yeah....I'm not a big fan of this sort of thing....but a 35-50 shot of NOS on top of that would do quite a bit...but I would use it sparingly, and get the type that brings the power on in a linear fashion instead of the empty-the-bottle-in-one-shot kind.

If you want more HP out of your 944, sell it and buy a turbo. Don't waste your money on $2k-$4k worth of mods like these people say and only have 180 hp (at the crank). And anyways, who wouldn't want a 951?

...yeah...I'd say go with the turbo....I just figured he meant what could you do with a N/A 944...

You should be able to get 40hp from just from increasing the 2.5L to 2.8L w/ tuning. If you serious about modding the n/a 944 id save and increase displacement & supercharge it. The superchargers can make 100hp @ rear wheels alone. If it were me id just save for a S2 and supercharge it. Although a 2.8L Supercharged 83 944 would be a nice sleeper! Its called "Nitrous" not NOS.... There are nitrous kits for the 944 Nitrous Oxide Systems (NOS) makes a kit for the 944 in both dry or wet. They also make Nitrous kits for go-karts also so if anyone is interested in a nitrous setup for there Honda Lawnmower or there Turbo Barstool you can make it happen!

in my opnion, the best mod you can give a 944 or 51 is a mass air flow sensor. Replace the stock AF meter with a MAF that sends a voltage to a massager that converts the signal from the MAF into one that the DME will understand. Autothority sells one, but its too expensive and they give very little info about it. Try www.lidseyracing.com ... they sell diff. stages of MAF kits but id recommend a stage 1 or 2 if you plan on passing emissions!! also if you go above a stage 2 you will almost certainly max out your injectors. If you change out your AFM at least make sure to check the injector duty cycle when demands on the engine are at a max.
There are probably other MAF systems you can get, but for best bang for your buck in terms of horsepower and responsiveness id go with lindsey. You can also find plenty of debate about the advantages of MAP conversions over MAF conversions....MAP advocates argue that MAF systems are ineffective once the weather changes after your dyno tuning because they dont account for air density...make sure your MAF includes an IAT sensor (Lindsey's does, dont think autothority's does). Not sure about actual HP gains on these systems but shouldnt be hard to find. I dont know it off the top of my head and dont feel like lookingit up. ANyway, this conversion works well on 944's and 951's but it really makes the 951 a truly awesome Porsche, because it gets rid of most of the turbo lag.
one more thing...if you have a 951 you MUST get a boost enhancer. It costs about $90 and basically prohibits any air flow to the wastgate until you actually want it. It comes from the factory set at 10 PSI and you can adjust it from 0-20 (im now looking at Lindsey's page). remember that any 951 is old....the wastegate spring was made weak and its now even weaker....usually the wastegate begins to open at about 5 psi and you start losing alot of your boost potential. with the enhancer you get NO loss of boost until your set limit and at that point, you better not have shimmed your wg spring because that extra psi needs to get out before something bad happens. They also sell cockpit adjustable ones but thats more $$

again i cant find the hp gain info...i just remember however that the stage 2 from lindsey although its not bigger than the stage 1, it has a much larger hp gain because it replaces the restrictive ducting after the AFM. If you leave this ducting there is little you can do to increase airflow although ditching the AFM will increase your engine's responsiveness.

87Porsche951, you can have your ports relined by most good engine shops.

Paeco can do it, you can order their catalogue from www.paeco.com
