I have a 65 Special that I'm messing with right now. I was gathering part's for a 350 Buick buildup, but not sure if that is the way I'm going to go with the car right now. A friend of mine has a complete 231 Turbo v6 out of like a 79-80 LeSabre, now before everyone jump's in and tell's me how much of a turd the early turbo car's were that GM attempted to produce, I have a what if question? Same friend also has a 4.1 shortblock sitting doing nothing. Does anyone know what kind of boost these early turbo v6's had? If I built a stout shortblock with this early turbo stuff, would it be possible to make any kind of decent power? The car will be getting a performance built 200-4r trans with a 3.73 geared 12 bolt rear. I'm trying to build something that will dip into the 13's on the weekend, yet still get 20+ mpg to and from work during the week o No: Anybody else have any other V6 combo's idea's??? Doing this on a budget to keep it fun and simple, and at this point the V6 has piqued my curiosity ou: I would bet the car is close to 3000lbs flat without driver, it has zero option's.
Go here http://chicagolandbuick.org/phpBB2/index.php? and search for member b4black. If this is who I think it is he is considered to be the guru on carberated turbo cars. I would also check out the turbo boards for help. I think the biggest problem is that there is not alot of aftermarket support for these engines.
www.turbobuicks.com check out the hybrids section... ask LOTS of questions... very helpful, though some are sarcastic at times.... look for a member by the screen name of "steve wood" very helpful and knowledgeable guy 4.1 can be built up strong; do a search on www.gnttype.org for "budget 4.1 buildup"... most look for the "291" block casting there are guys who have 86-87 intakes from the 3.8's that'll bolt right up to a 4.1, heads, etc. for sale and you can get a wiring harness built for the swap for your application from casper's electronics www.casperselectronics.com wes
also try www.turbobuick.com they have a section on the carbed turbo stuff. Honestly I'd not mess around with that, get an EFI turbo motor and use that 4.1. If you just want a good solid quick cruiser you can build a 4.1 for about the same as a 3.8, its when you get crazy, like me, the 4.1 gets more expensive due to the custom pistons mostly. There is a Hot Rod article on someone who did a 66 GS with a Turbo6 and honestly other than a G-body an A-body is one of the easiest things to swap a Turbo6 into. The big hang up I can see is a fuel tank, if you are willing to live with an external pump then its not that bad but trying to get an in-tank pump could prove challenging without resorting to a custom unit from Rock Valley Custom. I did a ton of research on this a while back so hit me up, public I'd like since others can use the knowledge, for info.
Doing this on a single income, 2 young children budget I should have made it clear, that I'm doing this on the cheap, VERY cheap :laugh: Single income household, so if I can get a 4.1 and a old turbo set up for dang near free, that is the direction I will experiment right now. If I had a complete wrecked turbo car at my disposal, then I would consider the EFI type of set-up. I appreciate everyone's input here, just trying to get an idea if it's worth trying? Or would I be better off building a higher compression 4.1 with aluminum 4bbl intake and header's? o No: Here's the car with it's new 15" tread's :Brow:
Tom, Awwwwwwwww turbos. I have thought about this a bit off and on too. I have a combo, "theory" that you may be interested in. Could be done on a tight budget, and make some decent power if someone wanted to experiment some. Basically, a few parts and a LOT of fabrication and time and I think you would be more than happy. And if your anything like me, I have wayyyyyyyy more time than money. Still interested in a phone call ? I'd give up the info/plan I have in my melon if your interested. Just know though, 90% of the people out there will tell you it won't work......................(but it HAS!!) PS- REALLYYYYYY liking the look of the car with your progress. Sleeperrrrrrr !!
The carbed turbo was designed to give the power of a smog V8 with the fuel economy of the V6. Its not a powerhouse but there are people that have done pretty amazing things with them. There were both 2 and 4bbl carbed turbo, if you can find a 2bbl I have a 4bbl intake adapter just hanging around. If you are going to build an engine, you can pretty easily get either a slightly heavier but more powerful 350 or a 4.1 V6 to do good things for a cruiser. Smokey Yunick made almost 400hp I think out of a naturally aspirated 4.1. Personally with a 4.1 myself I'd be partial to them. I also have a OEM 4.1L Aluminum 4bbl intake laying around but there are some good Buick V6 aftermarket intakes out there. Headers are hard to comeby for these motors as they tend to get pulled instead of hopped up. They are out there but not readily available. I love the first 2 years of the A-body, I'd like to put a single turbo EFI Buick 350 in a 4dr one with a TH200-4R for a neat open road cruiser and total sleeper. If you need help with the V6, most of the tricks from the Turbo6's will work on a NA V6 though you can tollerate more overlap in the cam and will have a different intake to deal with. www.turbobuick.com www.t6p.com www.turbobuicks.com www.gnttype.org (this is practically the best resource for information on the Buick V6 but its not interactive) I'd definately try to get a TH200-4R in it though for good mileage.
I can argue this point in depth. They CAN, and DO, make power if done correctly. Homework, homework, homework !!!!!!!
Kinda like this. No intercooler, WITH A CARB., and it runs 7.27@198.80 1/4 mile 4.72 @158 1/8 mile, on 10.5W's weighing over 3K #'s. I would suggest you forget all the same ole, same ole information that is out there now. And look at different avenues. This ole tried and true big compression and big cams is, while still ok for some I guess, not the norm anymore. Pump gas and 800 hp at the tire is a little more like it. Throw away what you "think" you know and open your mind. It can be done without using the same old boring routine. You wanna be different ? Then be DIFFERENT !! If not thats cool. Build an aluminum headed 463" with a TA 308S and some compression and make good power. Its been proven !, it works !!, but its old tech now !!!
Ok, heres something that I think is getting massively confused here. That picture is a BLOW THROUGH carbed turbo setup on a BBC race motor. What he is talking about is a OEM DRAW THROUGH turbo system designed at the end of the smog era for street cars wanting decent, for the time, power with decent gas mileage. While there are people making impressive power out of a B4Black carbed turbo motors the sacrifices to do it practically take the cars out of the range of a street car. If you want a turbo on a V6 Buick with out the less than optimal OEM drawthrough system you should look into getting a set of 86-87 headers and a 4bbl intake and go with a blowthrough system like shown. It would be more finicky to tune but definately cheaper and most of the parts needed are OEM stuff or easy aftermarket. I'd pick up the 4.1, add low compression Hyper pistons, a Edlebrock 4bbl intake, a flat tappet 212-212 cam, 86-87 Poston Headers (they are steel so easy to modify), a TA49 turbo or a rebuilt stocker to start off with, CSU 650cfm Holley and plumb the piping out of Summit or Jegs mandrel bends. Heck you could even add an intercooler that way without much trouble. The big problems I can see are keeping the turbo clear of the accessories because a distributor doesn't work with the LC2 serpentine system and I don't know what is in the way on the 4.1 V-belt system and getting the carb tuned right. Check out www.gnttype.org for the budget 4.1 buildup.
an 84-85 Turbo motor is an EFI non-intercooler motor not a carbed turbo. The carbed turbo was 78-83 on 3.8's with a 2bbl and 4bbl options. There are fast hothair cars out there (84-85) and with the introduction of a effective alcohol injection system there are some guys who have experimented with removing the intercooler entirely and just chemically intercool the charge. While this works well for racing it consumes a fluid that you have to replace and therefore is not good for a street car. A lot of people now run both a big FMIC (Front Mount InterCooler) and an Alky kit so they can comfortably cruise around without worries and still have plenty of power for a grudge match or a panic dash without the need for racegas. Heck mad scientist Bruce Plecan here in Ohio runs his 86 T-type on 87 octane and alky injection but he's significanly upgraded the car's electronics so that his Volumetric Effeciency is significantly above average and he runs a very tight tune.
i have seen a few with turbo v6s and i am collecting parts for a hotair (84-85) fuel inj setup if the engine is running ready to go give it a try . then decide if you like it.
E85 is around the corner any day We have a Meijer supermarket/ Gas station here in town that I'm sure will be the first to carry E85, and I think we will have it before next summer....My point is that in my reading, E85 run's cooler(85%Alcohol) and that along with it being around 105-107 octane, would be an ideal choice of fuel. Sure you will lose a little bit of mileage, but it's still cheaper than pump gas, and TON'S cheaper than race fuel. So either way I go(350 or some form of V6) I would push the compression ratio high enough to take advantage of the E85's Octane. I was really hoping to come across a set of the flat top racing v6 Forged piston's with 1.868 compression height to give the 350 some compression, but I've heard they are discontinued :ball: So if I have to look at custom made piston's, that kind of kill's the budget, unless I figure out a way to make a blow-through turbo 350 with low compression piston's :Brow: o No:
350 Buick # of Cylinders 8 Bore 3.820 Stroke 3.850 Gasket 0.020 Deck Distance 0.025 Head cc 55.0 Piston dome -29.5 rod dia 2.250 main dia 3.000 rod length 6.387 Deck Height 10.187 compression height 1.850 CID 352.99 Rod Ratio 1.66 Bore/Stroke Ratio 0.99 Static Compression 8.29 That's from an engine design calculator I built using a 0.020 over JE forged piston for a 3.8L Turbo6. Cost per piston is $86.99 from summit and is off the shelf. If you check with the various Turbo6 vendors they might have other good brands, I personally like Diamonds, in stock and can make you a 8 peice package.
turbo What do you need to know on installing a 3.8 turbo motor in the 65 special. I own the blue 64 buick special with the 87 GN motor in it.
I think those wheels look fantastic!!!!! :TU: I have a NOS set of those caps and a set of stamp steelies just sitting around. I always wondered what they would look like on the seafoam green car - awesome! :beer Can you tell me what size rubber you have there (front and rear)?
