8v bliss o.k long story short....I think your project sounds cool....I've got an H motor 8v with a t3 turbo..hugh fmic & would love to ditch the Cis for a mega-squirt. The problem is I've never wanted to go it alone. I think you guys could be of some help along the way with your project going as well. I would very much like some encouragement on going forward with the fuel system swap. Thanks. By the way Saabsbreakdown....I mange to adjust my fuel distributor to run 8psi thanks to your tips..but it's still just not enough for me...I want more. ![]() |

I dont have any advice apart from others have said, but Im very interested also. I plan to turbo my 99 a few years down the track, so I can learn a lot from this build. And its always good to see someone try something different ![]() |

hell if you can do that then it will just be keeping the cylinder temps. down. you said for intercooling you were gonna do a FMIC? the cars had their problems cooling wise mainly due to limited space between the the turbo/pipes and the radiator. you'll probably want to use your early style radiatior because they were thicker and put 2 spal fans in front of the radiator like a the real ones were. then shove the intercooler behind the air dam and use the duct for the battery cooler for the intercooler and put the battery in the trunk. thats the easiest and coolest way that i can think of. |

yeah the head cracking kinda sounds like its a no intercooler issue, probably combined with the overheating problems, i'm thinking that with proper intercooling, proper fueling and timing control, plus the knock sensor, it should be fairly reliable. i'm probably going to just run some coil packs from a GM car or something, controlled by megasquirt.

One problem you may have a problem with is a design flaw with the b-motor turbo. The all the stock 78-80's had a problem stock where they get the exhaust valves really really hot and at high RPM the valves will stretch or the head will crack. Also they had a big problem with detination and eating pistons at even 7.8:1 (i think thats it) and like 8psi of boost. But then again if you have that knock sensor you could use that to control ignition timing, are you going to run EZK? Marty will know more than I do since he worked on them when they were new hopefully he'll chime in. And by the way get out of my head. We just got a 77' Pre-production Turbo thats hashed and we thinking of doing this to a 76 99. ![]() |

and yeah the 16t really isnt that big, like i said im considering larger, from what ive read about the holset hx30 it supposedly is very similar to a t3/t4 below 10psi or so, but with much much more effieciency at higher boost levels, should be good for at least 350whp ![]() ![]() Quote:
you should go punch him in the face. hope all goes well for ya, and if i decide not to use the motor i'll let you know, i'm probably going to pull it out of the car sometime next week, so hopefully i can take a better look at the condition of the thing before i go making big plans for it. Paul |

And guessing who has not been answering my calls lately? Supposedly "the first week of November" was the latest estimated date of completion. Sorry for the thread jack. |

And as far as Greg's '79 99...you're getting totally hosed over on that car Greg. Chris should have had that done a really, really long time ago. He's taking you on a very long painful ride. if he hasn't taken the block and head to the machine shops yet then he probably is screwing you over. If he has taken it to the machinists, then he's being an asshole and not puting it back together. If that motor is not all cleaned and totally painted and polished I would say you are getting super-duper-screwed. |

Boy, I'd just skip all the way to a 16-valve turbo. I almost did that with my 99 Turbo, except that I made the decision to keep the B motor because the 99 T's are so rare. There was value in keeping the stock motor (which still needs/needed a full rebuild). The B turbo has no knock sensor, intercooler, an asbolutely terrible water pump which is getting nearly impossible to fix, they're prone to overheating and blowing head gaskets, etc. And you want to put a TD-04 on top of that? Plus, I'll bet it's the same amount of work to fit it in as a 16-valve would be. I forget the list, but there are a fair amount of differences between a '73 and a '78 99. (Oh, and BTW, can I buy your extra 99 T motor in case the guy who is rebuilding mine screws it up? I'm deeply afraid that might happen. Notwithstanding my interests here, my advice still stands.) |

Whoa. A td04? Nice. A T3 did great things to my 83. I can only imagine what it would be like with a TD04 and MS. While you have the head off, how about you take .04" off the top? ![]() |

B-Motor TURBO build? so ive been kicking around ideas for my 73 EMS, and lately ive decided on using a 78 turbo engine that i have from a parts car, supposedly rebuilt, but who really knows. thinking of putting my d-jet intake on the thing and running megasquirt along with a newer 8v exhaust manifold and most likely a TD04-16t that i have laying around. anything i should be particularly concerned about with the b-motor? im planning to give it a fresh head gasket at the least and was thinking about swapping in some later 9.0:1 turbo pistons to make it a bit peppier on the low end, perhaps along with my 73's original pre-smog cam. how high can i rev the thing without stuff breaking? Any ideas are welcome, and feel free to call me a fool and tell me to just put a 16v h motor in the thing ![]() terrifyingly, i might be the most knowledgeable person on here when it comes to b-motors, but i figured it'd be worth a shot ![]() Paul |
