i have a ? how would i make my 3.8 into 4.1 is it possible ?
Not directly... the 4.1 is a different block with siamesed cylinders.
You can use the internals from the 3.8 in the 4.1 (with new pistons).
how much $ am i looking at ballpark figure.i want to be a little faster than certain cars .tnx
I think you're asking the wrong question, or I guess I should say, can you be a little more vague? How about we try this again, you tell us what you have, mods included, how fast the cars are you want to be faster than, AND how much faster you want to be. With the question you asked, I'd say anywhere from 1-10,000, in whatever currency.
Really though, you shouldn't need to go to a 4.1. I think Jason of RJC is running in the high 9, low 10 second zone (so far I think a 9.96 @ 133.5mph) with a 3.8. And if you want to run faster than Jason, starting with an 84 with no mods, I'd say to atleast double that figure I gave you.
ok.....an 84gn is capable of low 12s to high elevens with a moderate amt of coin. you will need to update fuel system, ie injectors ot disc style, fuel pump, and adjustable f.p. regulator. stock turbo is sufficient enough, if you want high nines you will need to change turbos and torque convertor. replace stock air box with cone style or cold air kit for better induction. as far as a 4.1L there is a lot of coin involved with building one of these and in my opinion is not ness for the times you indicated you want. question is "jason" running a hot air car if so he might want to let us hot air guys in on his secret formula....my 84gn is running modified cam, fuel system, induction system, slightly ported turbo housing and dual 2.5 exhaust with cat hollowed out but essentially stock otherwise. 1/4mi times are 12.2 @114mph. motor currently appart for some more goodies, headers, girdle and block mods for better oiling(a nessesity if you want anything below 13's with any kind of reliability) good luck with mods, any ?S give me a shout!
ps...the stock intake manifold is very restrictive, some light porting will do wonders!
Great info Sam!
Would you consider writing up your "Recipe" for the Performance Recipes section of the web site? It doesn't have to be formatted or anything, but the text needs to be accurate.
It would be a nice addition ...
Sam that's impressive. I haven't gotten that low with my 87 GN yet, course I need to find time to tune the darn thing, school sucks up both time and money. About Jason, here's a better thing for you to look at http://www.gnttype.org/carofthemonth/archive/91thru120/sub117/comdetails1.html
I'm still curious about Jose though, he's never filled us in on what he has or how fast he wants to go?
I have an 84 t-type and I want to beat a 2000 Firehawk and some 2000 Trans AMs. The guy with the Firehawk said he beat an upgraded 87GN. My 84 is kinda run down and needs alot of motor work and interior/paint. Thats why I'm asking what I should do because I'm gonna rebuild the whole car and I want to do it right from the start. Appreciate all of the responses.
Jose, it's kind of hard to judge how fast that is, if you know what I mean. Any way you could lure, I mean explain to them that they really don't know how fast they are unless they go to the track? ;) It would be easier to help build your car if you had a range to shoot for. I'm sure others will say this too, but street racing really isn't good. I'm not just talking about accidentally killing an innocent bystandard, or getting caught and losing your car to the police, forever. On the street you really don't get good traction, and there won't be any safety personnel nearby if your car does something it's not supposed to do. Without good traction, you might as well not race, you risk damaging the motor from over revving while spinning the tires. I would build the car to be as fast as you can afford and want to go. For most people building a car, somewhere in the 12's is good enough. Past that and you run into rollbar requirements and more safety parts. On the street though, most 12 second dragstrip cars seem to turn into 13 second cars, atleast in my experience. And generally this is from lack of traction, even with good tires the street surfaces are a crap shoot. I'd get the car in good running order first, read all you can on the website, do the spring cleaning, and get a scantool of some sort. Then I'm sure things will come up that need attention and work from there. You'll get them eventually.
And if they are really bugging you about your car, see if you can find someone from your area that has a GN or TType that's running good and have them come by for some chicken, I mean Firechicken, I mean FireHawk.;)
thank for the info.im a new buick owner so i dont know much about them.but thanks alot for the info.
Jose, I just got an 84 T-type myself and am planning on fixing it up. Like you, the engine needs some tlc. I plan on doing everything right the first time, the only way to do that, in my opinion is to start with a budget. I made a deal with my wife to put a certian amount a month for my planned upgrades and fixes. When the parts cost a good bit, I will have to save a few months. I know it sounds pretty hard to do, and it is, however, that will give me time to do my research on the best parts to get for the car. There are plenty of web sites out there to go to for parts and research. You can also use google for your searches. Hope this helps.
Jack, that sounds like a great plan and it sounds even better that you included the wife and this isn't a secret. With her knowing she might even put some extra cash in there for you.
But as far as searching the net for info, this website is the #1 source of Turbo Buick info on the web, so you shouldn't have to go very far. The vendors listed on this site are the ones we need to keep in business and not to mention, you'll have some guarantee that they know what they are talking about unlike someone else you may come across, which will end up costing you both time and money in the long run. I know that there isn't as much info on the 84-85 as for the 86-87 but I'm pretty sure there are some recipes setup to follow. If you have any other questions you can always ask them here or just email the author of the recipe that interests you. The guys here won't steer you wrong, but there isn't that guarantee if you follow Joe Blow's advice that you stumbled across searching. I would search and read, but then perhaps ask about it here before you try it. Good luck on getting the cars where you guys want them, I know mine's still not done, hehe after 6 years.
shoot for low 12's if you run low 12's you should beat a stock firehawk especially if he's running a shitty 6 speed! my advice and this is what i'm doing right now... upgrade you injectors... Blue tops maybe.... adjustable fuel pressure regulator... 160 degree thermostat...new valve springs(lt1 Style)... change over to the 87 style computer, maf and coilpac.. then have someone burn you a chip for your setup.... you should be able to do this without spending over 5-600 $ tops... i also like and run nitrous but that is up to you.. do this and you should beat that damned ol firechickens..
