FWD intake

[Drac0nic]

while I don't think it's as good as the 86-87 turbo intake, I've been looking at the FWD SFI intake. The water line's off to the side, so it wouldn't interfere with the front end stuff like the 86-87 intake does. while not the turbo intake, I"d bet it's a step up from the 84-85 intake.

I tried posting this a year or so ago. I got no response. I think it looks likre a good deal and will try it eventualy. If you try it let every one know how it works.

got the intake and fuel rail floating around, you'll need another harness for the rail if you use an 86/87 like I've got, I'll tell you that straight out.

Can anyone else provide any insight into using this intake on a 84-85 TR? I'll be running a Powerstroke IC on the car and would prefer NOT to reuse the factory intake manifold. Can the intake just be flipped? Can any other associated parts be resued (like the fuel rail)? Etc., etc.

Thanks,

You can use an 86/87 intake and you don't have change your front accessories like everyone typically does. You don't even have to change your exhaust. What you do have to do use the following:

(all 86/87 parts)
t-body and associated pieces (tps, vacuum block, IAC)
plenum
throttle cable and bracket
modified water neck.

(also will need the 86/87 ecm)

You will have to slice the plenum some to allow your turbo to fit, modify the 86/87 water neck, and modify part the alt bracket. I will be doing this setup with an IC, but you could route the piping right back into the t-body for the hot air purists. I will be fabricating these pieces and working with bweavy to offer them, so if i can help you out let me know. I must give credit to Mark Green for his ideas.

Take a look at the pics.

How did you route the piping from the compressor outlet??? Did you go around back??? Is the turbo blowing down and then routed around the side???


Are you running this yet??? You will find the the piping that is coming from the compressor side of the turbo into the IC will get VERY hot...Not a good idea to run it that close to your coil pack/spark plug wires...

BUT, a nice clean setup, BTW...

I'm a little confused as to why so many people assume a ported hotair intake is worse than a stock 87 or FWD intake. You guys are going to a lot of trouble to run these alternate intakes off of assumptions. I would be more than willing to run my car against any of these cars with 87 intakes.

FJM,

I don't have this setup running yet on my car (waiting for it to come back from the paint shop). My friend Mark Green does, and he has great success with it as does at least one other board member. Yes the turbo blows down into the pipe and then it comes up, over, and along the valve cover. The heat by the coil pack could be a concern. It will be something i'll keep an eye on thanks for advice. Perhaps a heat sheild could address any issue.

Cool84,

I don't think putting this 86/87 is much trouble at all, especially considering the minimal cost. I think the total cost i have so far is 350 or so and that?? And that includes intake, IC, t-body, plenum, sensors, t-cable, IC brackets,t-cable bracket...etc... I still have to make the pipes, but thats it. These spearco and other kits for go for substantially more.

The intake is only part of a combo, so you can run your car against anyone else if you want and win, but that doesn't mean the intake flows better or worse. Unless the two cars are identical except for intakes, the "race" won't mean nuts... Do you have flow numbers for your intake vs stock vs 86/87?

I did have it flowed years ago. While I don't remember the numbers, they were right there with the GN1 heads which was my goal. This is not bad considering I spent $50 and did it in my garage with about 30 hours of my own labor. While I am running an intercooler, I wanted to keep as much of the original hotair components as possible and I considered the intake important.

I don't have track numbers but the car was neck and neck with a new Viper from a roll on 15psi (pump and av gas mix). I know for a fact a ported hotair intake will flow all the air you could ever need for 10 second and slower car.

 

[fullahotair]

It sounds like you got a pretty quick car - well done. If you goal is to keep hotair parts, then i can see why you would want to keep the intake. Like you said, you have evidently gotten your intake to flow well, but i would be surprised if a stock hotair flowed the same as an 86/87, but perhaps they do...i don't have any hard numbers, this is just my own evaulation of the intake designs. I have a ported intake myself that i was going to use.

However if you intend on getting an IC with minimal cost and perhaps minimal piping, then i would venture to say that utilizing the 86/87 intake conversion like shown in the pics above may be the way to go. As mentioned above, i only have about 350 in setup so far (all deals from this board and the other one) , but i still have to modify the plenum, and make some pipes, but i don't expect that to be all that much.

Its all the matter of how you want to go about achieving your goals, and no one way is more right/wrong than another.

soo ive read all of that and it seem really cool! but i stil dont see an answer to the question. will a FWD intake work on a hot air car?

sorry if i didnt see the answer

thanks

Does anyone have any pictures of these FWD intakes? What year cars did they come on?

Pics and info much appreciated.

Thanks,

Sorry I don't have pics. They look like an 86-87 GN intake. They're not quite as tall (smaller plenum) and they're one piece. Any mid-late 80s FWD car with the Buick 3.8L. They are all over the junkyards.

The V2 intake was flowed at 230 cfm per runner, I was told. Better then the 86/87's and same flow as the GN1 heads. The V2 is just a modified hot air intake. Why not modify your stocker??? -Nick.

That's what I've been saying for years. That's quite a bit more flow than a stock FWD or 87 intake.

I saw your previous response and thought I would chime in with what I knew on how well Jay got the V2 intake to flow. Nothing wrong with our stock intakes.-Nick.
