Turbo header pics.

[IThaJokaI]

Put up some pictures of your turbo headers. Im going to be building my own custom manifolds and I need some Ideas. So show me what you have.

Thanks,

try hmt.com alot of people make there on and they come out nice, should be able to find ideas before on here

[IThaJokaI]

Ive looked on HMT but I also want to see some professional manis so I can see what Im actually going for.

I will post some pictures tomorrow or Saturday. T4 divided dual 44mm

what are you making them for?

here some of the stuff that i've built

[IThaJokaI]

Im building them for my TT v8 corolla that I am currently building. Along with the help of Smokins13sr20.

ls1?

[IThaJokaI]

No, right now its between 302 sb ford and 305 sb chevy... I cant decide because, well I just cant lol.

are you planning on running a carb?

what intake and fuel managment are you planning on using?

[IThaJokaI]

Yes, its a 68' 302 or a 85ish 305... Both are carb. I will run a 600CFM carb or maybe bigger. Most likely run a 600 until I reach the max output and then go up. I dont want to deal with FM or anything of the such.

turbo carbed setups arn't the greatest. they will work, however you'll be re-tuning all the time.

do you have a plan for your carb setup yet? pull through or blow through?

[IThaJokaI]

Blow through. Ive heard nothing but bad things about draw throughs.

why would he be retuning it all the time?






and dude...dont even consider a 305...that is a waste of money. go with the 302. lot more aftermarket support. but get ready to buy a new block around 450-500whp.

[Sneakin Deacon]

also, there are a lot of alternatives you can use...if you are not too cramped for engine bay space, may want to jump on summitracing.com and check out part number ADD-717044, weld on some v-bands and fab up a Y pipe

depends on how close the turbo is to the intake and if you run a intercooler.

lots of vw guys run draw through setups.

carbs and turbos arn't a good mix. turbo cars are already hard enought to setup with efi, let alone a carb. there are more issues with carb/turbo setups, then efi/turbo setups hands down.

if carbs were a great way to fuel a turbo car, people woud be doing it all the time. its not very often you see a carb/turbo car that actaully runs reliably. i'm not the first person to say it and its not suprising to hear this argument.

if you guys are stuck on a carb, i'll shut up then.

[Sneakin Deacon]

its not that they are hard to tune, its that i don't think alot of people understand how a carb works. and most people use to just jet the shit out of their carbs so they would have enough fuel at WOT...but pig rich at idle..

if you take the time to fine tune the PVCR's size, you'll only have to up the jet sizes a little bit, rather than jumping 15+ sizes. if you wanted to run a 2:1 or even 3:1 rr fpr, you could feasably get away without touching the jets and just working out the PVCR sizes since the PVCR's only flow fuel during low low vacuum and boost, and the more boost there is, the more fuel pressure there will be.

[manifoldmike]

you can tune a car once for full throttle with little to no difference among atomospheric changes, however its the daily driver stuff that becomes a pain.

i've personally delt with my fair share of headaches with tuning issues. my beef is with idle, decel and partial throttle. even with a good efi system, they can be a pain. i'm not an expert with carbs, but i've had my fair share of war stories with professionals that are.

carbs were originally built for vaccum and arn't designed for boost. the cost of getting a carb to work properly on a boosted system may sometimes out weigh the cost of a good efi system. if its not money, its countless hours trying to get it to work properly.

i'm somewhat biased to efi because i'm a younger guy and i've grown up with it.

your right with the tuning and reliability, however to the average user, its not that easy.

tell you the truth, if it were my project, i would get an ls1 or a 5.3 truck motor with a harness, pay the $100 for an efi live copy and then go get it tuned.

sorry for the high jack.

if your making headers. its probably a good idea to run thick wall stainless of the head to a v-band clamp connection. from there on you can run thin wall stainless with bracing.

im young too, im only 21, and i've been on both sides of the boat as far as carb vs. efi.

EFI is just so fucking complicated, i hate complicated things. you have to adjust IFR's, MAP vs TPS vs IAT, speed density vs MAF, and the list goes on. it basically boils down to 90% of the time, you will make more power with a carb'd setup due to the intake manifold design, you get a much more direct and tuned runner with varying lengths. they LS1 guys using the carb conversions are picking up astounding amounts of horsepower just by doing the conversion.

i like efi for a daily driven car, but personally i think it overcomplicates everything in a race type car.

[IThaJokaI]

Well, in my case this car will be nowhere near daily driven. It will only be driven on the street rarely and when so, It will be at WOT 90% of the time. Im only 19, and Im nowhere near rich so the played out LSx idea is just not even there for me.
