Caboobaroo Posted September 26, 2004 Share Posted September 26, 2004 Well I'm planning on putting a Datsun pickup solid H190 rear axle into my Brat. I also am planning on doing a 4-link setup in the rear but I know I'm going to have to custom make it myself which shouldn't be too tricky. I just need some help trying to figure it all out and make it work. I am planning on building a tubular chassis that I will have the front end, rear end, motor and tranny mounted too, then I am going to drop the Brat body onto it. If anyone knows of a good website that explains it all and would help me plan out my setup, lemme know please:D Link to comment Share on other sites More sharing options...
bushbasher Posted September 26, 2004 Share Posted September 26, 2004 I suggest you read up on terms like antisquat %, instant center, roll axis etc. Heres a program that will calculate your variables based on the link system you draw up. http://www.performancetrends.com/4link.htm Link to comment Share on other sites More sharing options...
oddcomp Posted September 27, 2004 Share Posted September 27, 2004 sure copyt the setup i taked about using.... i see how you are... lol Link to comment Share on other sites More sharing options...
Caboobaroo Posted September 27, 2004 Author Share Posted September 27, 2004 well the front suspension setup would also be from a Datsun pickup as well. The motor is going to be a Chevy 2.8 v6 and the transmission is a Borg-Warner T5 5-speed. So basically the only thing left that will be Subaru will be the body. I am hoping to build a Brat drag car in a way. Running 11 second 1/4 I hope:D Link to comment Share on other sites More sharing options...
subusolo2nut Posted September 27, 2004 Share Posted September 27, 2004 You can also goto Amazon.com & look for Suspension design books--I've always liked a book in my hands--and a computer in front of me:grin: Link to comment Share on other sites More sharing options...
LUVMYBRAT Posted September 27, 2004 Share Posted September 27, 2004 Hey Caboo are you taking chassis fab after your core program? if you are then you'll be able to get all your answers there. I've seen a few done already, there was a kid, I say kid because he was only 17, he took a older ranger, put a 4-link with air bags placed midway with the axis point almost at the center and 2-1/2 ton rockwells gave him over 36 in. of adjustable travel. there alot you can do with a welder and the right calculations.

Rooinater Posted September 27, 2004 Share Posted September 27, 2004 if you are planning on using it for offroad. which i'm guessing not too much. since you are planning on dragging it. you can look through the pirate board. there's a lot of info on triangulated 4 links for offroad and other uses.

Pirate board? Whats that and do you have a link to it possibly? Yeah offroading is kinda out of the question with a lowered Brat. I tend to go offroading in large trucks but if I want the occasional Subaru wheelin, I know people to go with:D Link to comment Share on other sites More sharing options...
bushbasher Posted September 27, 2004 Share Posted September 27, 2004 the pirate board is a rock-crawling site. They have lots of 4-link stuff but it's all for making huge flexy monsters not for drag cars that want to hook up best on a launch. i doubt you'll find anything other than some definitions, but even then the definitions will be in the context of rock climbing.

MorganM Posted September 27, 2004 Share Posted September 27, 2004 Also I wouldnt post a question on there unless you like getting flamed from every angle Link to comment Share on other sites More sharing options...
bushbasher Posted September 27, 2004 Share Posted September 27, 2004 yeah forgot to mention that. I think you have to sign up to use the search, but I really wouldn't bother posting a question, seriously. Link to comment Share on other sites More sharing options...
Sweet82 Posted September 27, 2004 Share Posted September 27, 2004 Russ, That Brat is going to Scream! The Pirate board is not the most freindly place around. What about good old fashion leaf springs for the rear? All the old muscle cars are making them work? Good luck with your project. Link to comment Share on other sites More sharing options...
Caboobaroo Posted September 27, 2004 Author Share Posted September 27, 2004 I could start off with leafs and then eventually go with the 4-link down the road......but I'd still like to know of a place where I could read up on it and so I can start figuring it out:D Link to comment Share on other sites More sharing options...

Subafreak Posted September 27, 2004 Share Posted September 27, 2004 Not to be an rump roast or anything, I think most of the idea sounds cool.......BUT...Why in gods name are you going to use the worst V6 GM ever made? Link to comment Share on other sites More sharing options...

I resent that. The FWD 2.8s are crap. This will be from a RWD car. I also have a set of twisted wedge aluminum heads for it plus a set of 350 rods with the offset shaved off of them....all I have to say is 12:1 compression. I have one of these motors in my 1988 Camaro. It has 148k on it and I need to mess with the timing again because I screwed it up but it runs like a champ!!!Besides, its one of the smallest v6s and it fits better then any other v6.....so QUIT TALKIN CRAP ABOUT IT!!!!! I hate it when people do that, sheesh.... Link to comment Share on other sites More sharing options...
Subafreak Posted September 27, 2004 Share Posted September 27, 2004 Sorry, I've just never really heard good things about them, let alone someone building one up. I'm used to the ones in the Blazers tossing rods through the blocks, and they were real pigs in thoes trucks. Now that you mention it, they weren't a bad motor in a Camero with a 5 speed, moved out pretty well. But why not go with a Subaru drivetrain? AWD with an EJ turbo motor could get you into some low numbers, no? Link to comment Share on other sites More sharing options...
TomRhere Posted September 27, 2004 Share Posted September 27, 2004 Really, I go along with the comment on the 2.8 being a junky engine. On the otherhand,.... A nice beefy 4.3L with, proper talking, to would do you good. But that's just my opinion. On the 4-link part. Think you'd find some good reading if you went to the hotrod magazine site and did some reading. Draggers have done 4-link rear suspension for eons just about. There should be lots of info in their archives. Don't have a website link for them, otherwise I'da put in here..... Then there's the 5-link setup. Still dun't know what that's all about, but it's supposed to be better. Find myself wishing that I had kept closer ties with my old drag'n days. Lot's of good times, lots of good friends. And humongus HP about the place. Gotta love it!!!!! Link to comment Share on other sites More sharing options...
Caboobaroo Posted September 27, 2004 Author Share Posted September 27, 2004 because I like the thought of a 2.8 and I also have the heads also and performance parts are readliy accessible Link to comment Share on other sites More sharing options...
TomRhere Posted September 28, 2004 Share Posted September 28, 2004 Spoken like a true "Hot-Rodder".... I have this, and that, some of this, some of that. I don't care ifin y'al dun't like it! This is my dream, my ambition, so there............ Wish you thew best on it............................................................ Link to comment Share on other sites More sharing options...
Rooinater Posted September 28, 2004 Share Posted September 28, 2004 haven't had a huge problem being flamed there yet... keep it straight to the point and don't mention the vehicle... Link to comment Share on other sites More sharing options...
bushbasher Posted September 28, 2004 Share Posted September 28, 2004 ...and don't mention the vehicle... no kidding Just search, if you make a stupid first post it'll take a long time to gain some face back, and don't come back at them with an attitude either. Of course who really cares if your goin to ask 1 question and then leave. Link to comment Share on other sites More sharing options...
