Turbo plan/questions

Alright laying in bed thinkin, what are the advantages or disadvantages to recirculating or venting to atmosphere?

[AustinSilvia]

i've never actually used or seen (in person) a recirculating bov. i know they are out there but people buy atmospheric a lot cause they sound soo damn sweet.

just a question... why do you say "infamous ssautochrome manifold?" i think it's probably the best out there for the price. they have 2 of em, one with their turbo kit, and one that just comes with a down pipe. the equal length one that comes with the turbo looks pretty damn sweet. anyway i got one and it seems to be done well. the welds aren't the prettiest but i doubt it'll fall apart easily. i'll let you know how things turn out. it costs like half of what the cast iron log manifolds and crap like that cost... log style... i could make a better manifold than that with my dinky little mig welder and some pipe from home depot. anyway just curious to see if there's a reason why ssautochrome's is apparently infamous...

Well with atmospheric, you get a loud sound.. but you have to run the maf as a blow-through, or else you'll run really rich inbetween shifts.

I don't think there's any advantage or disadvantage to running either besides the sound.

Previous SSAutochrome manifolds were notorious for cracking. Allegedly, the new manifolds are a revised design that doesn't have this problem, but only time will tell.

Someone on another forum alledges that an old-style SSAutochrome manifold destroyed his turbo. I take that with a grain of salt, but it really sounds like the old design had problems with cracking.

The new ones are certainly cheap, and they might hold up well. I suppose we'll know in a few months. Personally, considering the price I wouldn't be too terribly upset if one cracked. They're so cheap they are almost disposable. Usually, you get what you pay for, but I guess we'll see with the SSA manifolds.

How much are the SSA manifolds? My jgs log manifold cost me $120.

Whats anyone think about the EDT manifold here for sale on Nico? It looks really nice to me, and would give you much better master cylinder clearance, but not so far forward as to give you problems with the distributor... But $400 good?

yeah time will tell. personally i don't have any past experience with them, but we'll see how things turn out. like i said the welds are strong, although not the prettiest. for my application i kind of doubt i will run into problems, but you know i'm definitely running a low end power budget setup, just to give my car better overall balance. i'm not focusing on making major power, just building a reliable balanced car... like you said they're not really expensive so taking the chance to see if this thing flows better and performs better than a log manifold is something i don't mind doing. they'll hear from me if the thing cracks, but i doubt they give a crap. they're just a bunch of guys throwing crap together who happen to have a tig welder...

by the way, for whoever was asking about the ssac manifolds there are 2 different ones on ebay. one that is included in the turbo kit (it is an equal length tubular manifold that will house a t3 or a t4... this is the one i have). the other one can be purchased seperately from a kit and it is made for a t25 or t28... it is basically the same a an sr20det manifold. the first one, that is part of a kit, well the kit can be had for like $800 or so... it includes turbo, manifold, wastegate, bov, flanges (all except the damn turbo exhaust flange for the down pipe, which is an odd flange, that is less commonly used), and all gaskets, bolts and everything to hook it all up. problems i have run in to include: the flange from the manifold where the turbo bolts... they decided to thread the bolt holes... maybe not sucha bad idea, but they did a crappy job of threading them so basically that sucks. the manifold barely clears the brake master cylinder and lines, so we'll see if my brake fluid boils and my brakes fail,.... i'm making a heat shield, and we'll see how things go. other than that there aren't too many problems so far. i have to break it all in for about 500 miles and then i'm ready to go for the most part. if you do decide to buy this kit or anything from them, they don't include good intructions. you'll be better off asking people on the forum what you should do. discard what they say about the install cause it's all bad advice. anyway so if you're looking for high power i'm not going to reccommend this kit or anything but like was said before they may or may not have a history of cracking manifolds and we'll see how things turn out for my car. oh by the way the other manifold (sr20det style) by itself with gaskets and bolts and stuff costs about $200 or something like that.

Seems like a created a useful post. Ther is tons of onformation in this thread. Thanks to everyone

bump.....

just too much good information.... THANKS

regarding BOVs. somewhere i heard that a recirculating BOV lets more pressure build up during the shift and therefore gives you more boost after the shift. since youre usually at a lower RPM range after an upshift this will would give you some boost where as usually you might not have any at low RPMs.

im not sure at all if this is true or not but does it sound right to anyone else?
