Ok, I feel bad about jumping into everyone else's questions so I'll post my own. I have an 88 944 that I'm putting a 87 951 engine into. I'm wanting to go with the 35mm Tial W/G from SFR and possibly dump it to the environment instead of the exhaust because my W/G has all the studs broken and they've been known to get weak with age. As far as dumping it to the side, I just think it would be cool IMO. Also, I want to use a 928 GTS fuel pump and adjustable FPR. Iwant to turn the boost up, but it will be next season till I can aford a turbo,So how far can I push the stock one? I vented the front pan for air to the I/C and I'm thinking of doing a water sprayer on the outside of the I/C to keep the intake temp down. I have an ARM1 to keep an eye on the A/F and was wondering what other guages are useful besides boost? Plans for a custom 3" exhaust turbo back are in mind. Cold air intake also with my own MAF, What kind of A/F controller is recommended? TIA

About 16-psi or so is max for the stock turbo. It will still drop to about 13psi @ redline no matter what.
" Cold air intake also with my own MAF, What kind of A/F controller is recommended?"
You can use our <a href="http://www.gururacing.net/DigitalMAFupgrade.html" target="_blank">Intercept-Link</a> to turn your MAF into a modern digital unit. This controller provides the same 3D (load vs. RPM) mapping and adjustability as our MAP kits or the UNIchip. Very easy to install and it comes with a pre-programmed map that should be in the ballpark for most MAF sensors.

Hey Nine-44,
It sounds like you've got the motor swap worked out fairly well. I'm curious; are you upgrading the trans, suspension, and brakes in that beast as well? Did you find a complete 951 donor car? I'd like to make a trip down to Cinci to check that out sometime....

I hate to post the obvious...but someone else is going to eventually.
Why not sell the 944, 951 engine, and just get a 951? Would save you a lot of headaches, and would make more sense.

I plan on playing nice for a bit and then go for the trans, big reds, swaybars in the next year or so. I won't be doing 160 very often and the car stops pretty well in stock N/A form. Already have the Fiberwerks nose and vented my front pan to move air to the brakes, intercoller and eng. Also have turbo struts and brake ducts for the 951. I looked in my Euro select and the N/A vs. 951 trans. part #s are the same except the 1st and 2nd gears and the cooler. The shafts are the same also. My reasoning is this, I had an 88 944 black on black, totaled it, Bought it back from insurance and planned on re building it with a salvage title. Then ran into a fairly straight 88 944 silver on burgundy at a descent price. My plan then was the black car as a donor for drive traine and interior. Had that engine from the black car ready with all new head set and seals with belts, ready for install, just waiting for the silver car to be sprayed yellow. Had the car edged in, sitting in primer, ready to spray, Got a call from a guy that needed a few parts for his 87 951 that was getting a V-8 swap(Not my taste), Asked what was planned for the 951 leftovers, Ended up getting everything I needed pretty cheap. I had plans for the extra eng from the silver car to get built into a twin turbo home cooked, so I knew the costs involved. This is way cheaper to do. <img src="graemlins/xyxwave.gif" border="0" alt="[bigbye]" />

BTW, I have more fun working on it than driving it. It's still alot of fun to drive though(when my license gets square again).It's a challenge to me, to build it up vs. just buying parts or kits or paying someone to make my car fast. As far as the life of the trans, a guy I know(Derric Macey on the cover of Sport Compact with the yellow Type R)He's pushing a SUPPOSED 4-500 HP at the wheels with a trans I could probably lift with one hand, I don't think Porsche puts out junk, so we'll see. Oh yeah, He can't keep rod bearings in it and he can't work on cars either

the NA tranny is fine if your installing a stock turbo motor. I wouldn't push it past the turbo/chip combo though. But I know it will handle 200-215 at the wheels all day long on the big track, driving hard as hell. I would not start drag racing with the NA trany, but opunching it on the freeway, and spirited driving around the town and back roads will be ok. As far as the brakes, those too, as far as we have learned are good also. We have our NA putting about 225-230 at the tires right now running it on the stock 84' brakes and calipers with no problem on the track, we keep them well vented, although for street use, you should be fine.
Again, I am only saying this because we are doing it right now, on the stock brakes in our race car, we just upgraded the tranny with a shorter fifth gear but its still an NA. We are planning to bump the HP up to about 250-260 at the tires for the next race season coming up in feb. And will still run the brakes and tranny until we are forced out of them.
Take Care!

I agree with Anderson-
The way nine-44 has approached this is really pretty logical and actually sounds better than most people upgrading their 944 turbos without considering half the things he already has. As far as the trans cooler- I wouldnt bother buying an OEM one unless you get a deal on it from a salvage yard, as you can make one up for a reasonable price yourself.
I would highly recommend a stand alone engine management system for this car, or at least the link system Danno mentioned above- better safe than sorry. As I have said before- I dont like MAF conversions, but there are plenty of them running around with no problems at all.
nine-44 you should have a pretty good car when you are done- although I would recommend instead of big reds and the turbo box using AP brakes and a 968 six-speed box, but thats just me. Good luck on your project!

<img src="graemlins/soapbox.gif" border="0" alt="[soapbox]" /> No offense (really, and not directed at you personally Elon), but those statements really torque me off. If someone has a lot of time, money, blood, and effort into thier n/a and know exactly what they have and what they are in for, then there is no reason to ditch the car and buy a 951. I mean, seriously, look at all the effort I have put into my n/a. Would I REALLY be better off selling, buying a 951, and then spend a lot more time and $$$ getting it just up to the same shape and state of repair mine is in? (brakes, suspension, wheels, interior, etc, etc) If all I want is around 220-250rwhp, then I already have a great platform for a supercharger or Anderson N/A motor. If I want to do what nine-44 is doing, I would still be ahead by buying the 951 donor parts and getting my hands dirty. If someone is a fairly decent mechanic and likes doing the work (like most of us on this board I would guess, otherwise we wouldn't own these cars) there is no reason that this is not do-able.
Pleeze. Show me a 951 for under $12K and I'll bet that the person that buys it will have additional receipts for at least another $5K in two years time if they actually drive it. So the financial point of this argument is really moot. Besides, no real "penny-pinchers" should own these cars. They are an addiction and will nickel, dime, quarter, and dollar you to death.
So I say wrench on, nine-44. Let me know if you need any suspension or brake help and I'll come to you when I drop some horsepower into mine...

Anyone have any Ideas or comments on the side-dump W/G? I may not go with it being that I'm not seeing anywhere to run the pipes(without them hanging low and getting knocked off on every speedbump) and I don't want to dump it under the car. I,myself, think it would just be too cool, but if it will have adverse affects on performance I'll scrap the idea. I'm not a pennie pincher, but heres the kicker, I'm 23(almost 24) and I've got a Sh*tty job $7/hr(for now, until my license is square). I just use careful budjeting(I spend all my money on the car). So money moves slow and it will be done, I'm just tryin' to have fun in the only way I know how to.

Well, I think the way nine-44's approaching his project is a more comprehensive than most people who just wants to slap on a turbo. I think I've read somewhere that he's got the entire engine-harness along with the computers, not to mention all the mechanical bits like headers, crossover, etc.
As for the wastegate dump, you can actually route it out the passenger side just ahead of the door. The closer you keep it to the tire, the less likely it'll get banged by something. Then you can also ovalize the tubing so that it's just 1" high x 3" wide or so.
For the exhaust, if you're mating the downpipe to the stock 944NA exhaust, I would at least get a straight-through muffler. That's because 'turbo' mufflers by design are more free-flowing and do not block out as much exhaust noise since about 1/2 of it has already been taken out by the turbo itself.
If you're still having problems with that 14-pin connector, send me an email and I'll work up a cross-reference table for you.

Still need the 14 pin diagram, as for the exhaust I'm planning on a custom 3" from the downpipe back. I may get an SFR or similar downpipe(looking at prices ofcourse). I did buy everything engine related for the 951, actually the guy called me tonight and wanted to trade my N/A surge tank for the coolant B/C he only needs on connecting hose for the V-8
. As for the turbo after run cooling, how is the system set up? Does it just run a relay for the fans and pump off the temp switch on the turbo? Thanks
