98+ Firebird side vents for intake

[T-Punk]

since my turbos will be back in this area anyway i was looking at using the side vents for my intake. I think i could fit a decent size cone, tube, or oval filter in there behind the vents. i know i would have to go through a lot of work to change/clean my filters but what my question is would there be enough flow throuth this area to make a good intake. my worry is that it would have negative air pressure in this area when im moving. please help.

don't think this is possible effectively.

ok, i wasnt sure. I just thought it was good because it would keep my intake from getting mud up in it and would get cool air if ther is enough air running in there. I'm open to suggestions though. My turbos are going directly on the manifolds and my piping up to the IC's are going incon style through the suspension via rubber hose where it goes through the suspension (dont want to have to worry about a metal pipe going through my suspension). I just can figure out where to run the intake for my turbos to. I need some ideas.

To be brutally honest, I would NEVER go for a setup like yours. It is a mix between a front turbo and a rear mount turbo, overall, bad idea. The heat from the engine is going to build up MASSIVELY with the two turbos there. THe oil system will NOT be fun and neither will bolting everything up be fun/easy.

I hope you have a LOT of patience and time for fabrication. A LOT. I do not see how the intake for your turbo will possibly be cold once it hits it. With it that far back, right next to the manifolds and engine, it is pointless. Just attach a filter directly to the turbo, you will probably get the SAME effects.

My advice: Take a step back. Is this really feasible? Do you really have this much time, patience and money? Will it really be more effective and as powerful as someone's turbo kit, such as Tiago's? You are venturing a little TOO far here I believe. You seem to still be an amateur with all the posts you make, get experience then try harder things.

I think what he means to say is that go for it but just know that theres a good chance what you are making wont work out the way you hoped... :D

have you ever seen the incon kit? it has the turbos positioned in this exact same place and it was one of the best kits ever made for the LS1 F-body. The reason i want to place the turbos in this location is this is where the hottest air is in the exhaust, the hotter the air the higher the velocity, the quicker the spool. I'm not trying to outdo tiago, i dont have the knowledge to do that you are right. I do think however with all the schematics i have of the incon kit i can replicate something very close. What i am trying to avoid (and was hoping this post would present a solution for) was having to run the intake pipe for the turbo all the way to the front of the car through my suspension. I also dont know why you think the air would be hot in the part of the car i was talking about puting my intake (its not even near the engine its up inside my body and is seperated by plastic and metal from the hot innerds of my car). The spot i was talking about is inside the fenders behind the tire (on 98+ there are two vents on each side and i was hoping this to be enough to get sufficient airflow to my turbos). However i was fearful that there would be a venturi effect in this area when im moving which would actually suck air away from my intake if i were to place it in there. Just clarifying in case you misunderstood, if you still think this would get hot air explain dont just say it wont work and not tell me why. Now as for the turbos making my engine hot... i think thats pretty much a given of any turbo system, but they will be water cooled which will help a little. i also plan on getting a bigger radiator, an oil cooler, and a trans cooler. I know my engine compartment will be a lot hotter because of the turbos but i think all of this will help me out. Also if i can afford it i will probably go with a pair of aerocharger VATN's to make everything easier (including oil systems because they have there own sepperate oilling system) As for my fabrication abilities, they are up to snuff and i am fairly proficient with working on engines. Also i have more patience than anyone i know (im planning on this taking the better part of two years to complete). Now as for tiago, i have nothing but the upmost respect for him and his kit and if you look in my past posts you will find that I always tell people to just buy his kit because i know most people dont want to go though what i am planning on having to deal with. The reason im doing this my self is because i take pride in building things with my own two hands and i dont want to have what everyone else has. I see you didnt settle for the average set up as well. Granted you had the turbo god himself fab it for you but still. You have probably got the best turbo'd car on this site and i hope to see what you can do when you get the whole kit ironed out. Oh and as far as oiling being a nightmare, i have to agree (unless i go with the aerochargers like i said erlier). I know im going to have to get a scavange pump and do all the plumbing and mounting for all that as well (i planned on that already). Now as for me being an ametuer... i admitt i am not the fountain of turbo knowledge that tiago is but i do have a pretty good grasp on turbo technology. I'm not saying your wrong when you say it might suck, at least at first, but at least i am trying new things to see if they work so others will know.

Incon setup worked really well, where did they get air from? I thought they had a filter behind the intercoolers?

[T-Punk]

They did, i just wanted to use less piping through my suspension.

yeah the air was ducted from up front near the intercoolers to the turbos then ducted back to the intercoolers then on up into the intake..
2 filters 2 sets of ducts, 2 intercoolers combined up in front of the radiator where the windshield washer tank is..

[T-Punk]

exactly. Im just not totally secure with running that much around and through my suspension, but it looks like it might be the only way to get it done. If you have any other ideas let me know though.

[DavidSiri]

Not trying to bash you for your idea, if you go through with it and it turns out well, more props to you. I myself know that if I were to get into it, I would get very frustrated very fast because of all the potential problems you may run into. I am not a genious when it comes to turbos at all, all the knowledge I have gained has been from doing two turbo installs with Tiago, all the fabbing and what not as well as reading up. I COULD install a kit no problems I believe now with what I have done so far.

I am not trying to say don't do it by any means, sorry if you took it as that. Good luck with whatever you choose....

I hate trying to do complicated things in tight spaces, which is what I believe you will be doing.

[T-Punk]

Yeah, basically any real work on a 4th gen requires doing things in tight spaces. Im probably going to end up getting a second motor to build up with everything and then pull the old one and put the turbos and the new engine in at the same time (mine that is in there now will probably have over 75,000 miles on it by the time im done so its a good time for a newer engine anyway). Besides if it gets to far out of hand im sure i can sell the peices off at little to no loss as long as they are pretty new. But i have decided not to use the side vents, Its just not a good way to get enough air. So ill probably end up running it some other way to the front so i can get a lot of good clean cold air.
