Science Abuse Posted June 22, 2002 Report Share Posted June 22, 2002 deposited my check today, and found out *gasp!* I have too much money saved up! I must remidie this immediatly! What I've got is a 96 Thunderbird with the 4.6. It makes peak power (190 at the wheels) at 4200 and slopes evenly to 170 at redline. I'm leaning toawerd a turbonetics T-series T72, the 76 is a bit pricey. Can anyone recomend a Turbo for my application? I'd like to stay around 400bhp since the engine is basicaly stock, aside the replaced intake manifold. Any recomendations? btw, i dont have room for two, I'm looking for a big single. thanks edit: hjow about this, should I bid? http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=1838081925 [ 23 June 2002, 03:12 AM: Message edited by: BlackBird ] Quote Link to comment Share on other sites More sharing options...
20G TSi Posted June 23, 2002 Report Share Posted June 23, 2002 I might be wrong, but I think the T66 is a bit big for your application. Not sure, but since you're going with a single turbo kit, only 4 cyl. are feeding the turbo. Low compression and small displacement might make that turbo hard to spool without some chemical spool (nitrous). I know there are other more efficient turbos out there, but dont overlook a T3/T4 hybrid. they're really hard to beat for the price, and I'd imagine you'll need some extra cash to fab up a exh manifold/header and flange.

Bahnstoermer1647545488 Posted June 23, 2002 Report Share Posted June 23, 2002 I didn't know you could have a single turbo on a V motor.... that doesn't fuck up backpressure from one cylinder bank to the other? Quote Link to comment Share on other sites More sharing options...
GRN96WS6 Posted June 23, 2002 Report Share Posted June 23, 2002 Alex Alex Alex I am severely disappointed. Buick T Type and GN both have the V6 motor and a SINGLE turbo. tongue.gif Quote Link to comment Share on other sites More sharing options...
Bahnstoermer1647545488 Posted June 23, 2002 Report Share Posted June 23, 2002 Well to clarify.... it sounded like a discussion about using only 3 cylinders to spool the turbo, which is what sounded very strange to me. Oh and also not being a domestic guy at all, I know nothing about those cars to be honest with ya'll smile.gif Quote Link to comment Share on other sites More sharing options...

I've never been so insulted! tongue.gif 4cly!? 6cly!? Boich, I'm boosting a V8, 281 cui SOHC. ok, jokin aside... I am mimicing a kit made by TDC for the 4.6 mustangs. Given that all the tubing is chassis specific, the only thing I could use from the kit would be the T66, or t-76, depending on which kit you pick. I'mplumbing, fitting, and testing onthe OE engine in preparation for the aluminum, all forged, 6 bolt main, studded, girdled, and ported 4.6 SOHC taken to 8.5:1 and given everything that a T-76 can put out. I've decided to watch, and bid....Unless you guys know where I can find a T76 or T72 under a grand....? Quote Link to comment Share on other sites More sharing options...
20G TSi Posted June 23, 2002 Report Share Posted June 23, 2002 conventionally, single turbo kits for v8's feed off of one cylinder bank (thus, 4cyl feeding the turbo comment). Thats what I was talking about. sounds like you already know what you want. Quote Link to comment Share on other sites More sharing options...
Guest 1bad66duece Posted June 23, 2002 Report Share Posted June 23, 2002 i have some used stock gn turbo`s,but the turbo will be the cheapest thing you will need to buy,if you want it to last you will have to dig deep in you wallet!you stock engine cant handle much boost,but it may be fast for 1 or 2 passes down the track.

Doesnt your motor have the cast pistons? If so, you'll break/melt the ring lands off with a quickness with a poor tune. Quote Link to comment Share on other sites More sharing options...
Guest nevarmore Posted June 24, 2002 Report Share Posted June 24, 2002 i remember right there are some turbo setups on V engines with a crossover/crossunder exhaust tube so the single turbo gets power from both banks. Quote Link to comment Share on other sites More sharing options...

I've contacted a former ford engineer, current roushe engineer about this. My stock eninge is good to handle about 400bhp, 450 max. I'll spool the shit out of a T72 on the new moter, this one is just to play around. And, as for the tune, I'll have the best possible, a custom EEC reflash on a dyno by said ford guru. Were I'm about to get confused is choosing and operating blow offs, waste gates, and other such devices I know jack aout. Quote Link to comment Share on other sites More sharing options...
Guest relvinnian Posted June 24, 2002 Report Share Posted June 24, 2002 Show me: relvinnian@hotmail.com T-72 setup on your current engine will put you at the bottom of the airflow map. Not to mention for the setup you are planning you are going to have to significantly change the torque/power peak to accomplish anything. Simple fact of life, that motor needs to rev more, and become significantly more efficient. To give you an accurate indication, I'd need a dyno graph of your engine. Another thing to consider, you won't spool that T-72 properly on your current engine at all, if you design the turbine to fit the needs of a much higher flowing engine. A turbine that spools on your current engine would run out of steam on your eventual project. What's the stock compression ratio? Email me some plans.

rl Posted June 25, 2002 Report Share Posted June 25, 2002 The misinformation in this thread is great! He will be running a single turbo, running off of all 8 cylinders, you just run a crossover pipe and a Y infront of the turbo. His stock SOHC engine can handle 8-12psi all day long as long as it is tuned correctly. Look at TDC's single kit for the SOHC 4.6's, they make well over 400rwhp and are very streetable and reliable.

Guest neonfink Posted June 25, 2002 Report Share Posted June 25, 2002 Christ, your bird is gonna be built! I know a kid who has a 96 Bird, and he swears that thing is sooo fast. I laugh at him all the time, he says he has "special headers", but its just the stock exhaust manifold. I sure would like him to see your car (the tail lights of course) to see what a REAL TBird is. Id like to see your car sometime, too damn bad I live in Zanesville. Quote Link to comment Share on other sites More sharing options...
Science Abuse Posted June 25, 2002 Author Report Share Posted June 25, 2002 heheh, sure dude, I'll enlighten him I dont suppose it's a v6 is it? Those actualy got tubular headers stock! Good for about 145bhp and low 17's in the 1/4 Quote Link to comment Share on other sites More sharing options...
Scotty2Hotty Posted June 25, 2002 Report Share Posted June 25, 2002 I'd say the biggest injector size.....isn't there a 42lb. rl correct my cracka ass if I am wrong..? Anywho that set up seems FOCKIN WICKED AS SHIT! I can't wait to see this that is a nice list of mods I like it. Surely make that bird fly to say the least Good luck.

The biggest I've seen is 160#, yes 160#. They were experimental and used on a mid 7 second car. I've seen 50# for a reasonable price, but theres got to be something between 50 and 160. lol Quote Link to comment Share on other sites More sharing options...

Since we only use 4 injectors (primary and secondary), and flow alot of air, we need large injectors to meet the requirements. Rotaries also have poor BSFC, but that's another story .

Guest ST RACE Posted June 26, 2002 Report Share Posted June 26, 2002 Look in to a TE-60 , 42.5 but get 50's or as big as you might need down the road Find out were you stand as far as low/high impeadence. Stock F-body's usuly use some form of a 60 and run 6-8 lbs boost Quote Link to comment Share on other sites More sharing options...
Alex1647545498 Posted June 26, 2002 Report Share Posted June 26, 2002 well heck just buy the thing anyway... you can always change your mind and sell it on e-bay again... I mean the damn thing is cheep! Quote Link to comment Share on other sites More sharing options...

Unless 500+ rwhp is your goal, I wouldnt go with bigger injectors... especially if you plan on driving the thing daily. For general rule, use the following conversion: HP = (cc per minute / 5) x 8 HP = (lbs per hour x 2.04) x 8 (8 = Number of cylinders) Quote Link to comment Share on other sites More sharing options...
Science Abuse Posted June 26, 2002 Author Report Share Posted June 26, 2002 500+? 500 + 150 or 200 The new motor will have the shit boosted out of it, literaly as much as possible.And I drive it as daily as possible, as it will most likely be Fukin awsome. tongue.gif the curent set up will be the OE engine of my daily driver, SoI'd rather run rich then lean. Also, like I said, the EEC tune will set the fuel preasure, so I wont need to worry about over doing it no matter what size injector I use.
