Default question about turbo downpipe

hey guys, i just bought a turbo from someone for 1000$ (t3/t4 turbonetics) and the kid did not come with the downpipe. i found one on ebay from ssautocrome (yes i've seen your guys posts about how much they suck but i wnated to knwo if this product would be better than their headers)

http://cgi.ebay.com/ebaymotors...ZWDVW

and they are the only place that sells the pipe with the flex pipe / flange.

The SSAC downpipe will most likely only fit if you're using an SSAC manifold. The reason that it's hard to find pre-made downpipes is because each one will fit differently depending on the manifold design.

Your best bet is to get the exhaust flange for your turbo and have someone make you one that is guaranteed to fit (or buy a welder and learn how to do it yourself).

yeah most likely its not going to just bolt up to fit your manifold and turbo. if it has the right bolt pattern on the downpipe and you really want to getit you can and hopefully a local exhaust shop can take it and moddify it to fit.

when i got my turbo and downpipe they were mocked together and i still had to completely modify the down pipe to make it fit with the F'ing from cross member in a prelude.

well its the whole downpipe though.. and i went to an exhaust shop today and he said that i'd probably be better off buying it somewher eelse b/c its going to be really expensive from them. plus the way my manifold is the turbo is on the top of the mani. so im going to have to add / modify it anyways

a downpipe is completely dependent on the manifolt and turbo in order for it to fit. you need to make sure the bolt pattern is the same on the DP as your turbo, and then ask an exhaust shop if you but a generic downpipe if they can chop it or add in a peice to make it fit.

first.....let me get this off my chest......

<FONT COLOR="red"><FONT SIZE="4">$1000 for a turbonetics t3/t4!@@#@$^%^!~!!!!</FONT></FONT>
- Hey, i've got 100 acres of land in Madagascar that i'll give you for $1000.-----you could've bought a precision sc61 for 700-800 new......you're crazy!....

ok, now that that's off my chest-

you will have to make your own d/p, or get someone to do it for you. a d/p and manifold and turbo have to be made for eachother. if you change one of them, then the one or both of other two will have to move in order for everything to fit together. so you will have to get one made. luckily, it's not that hard.....just buy 2- 2.5" or 3" 90* stainless steel bends, depending on what size d/p you want, and a flange for the turbo, and cut and weld where needed to route the piping down into the exhaust. the chances of you finding a d/p that will work are slim to none unless someone makes one to your particular setup already. you will also have to cut into your crossmember most likely, which isn't that big of a deal.

Good luck man.

ok....the deal wasn't quite as bad as it was before. but i don't really know where to start.

first- that mani looks like the old drag kit manifold i think.

second- PLEASE, for the love of God and all that is sacred........don't turbo your poor Prelude using that VAFC and an FMU. you won't get a good tune and that motor isn't going to last you very long man. you need a standalone, some good injectors (i have some 680cc's for $200 shipped), a fuel pressure regulator, a walbor 255lph pump, and a tuner that knows what he's doing.

if you get that manifold from him- they actually did make a d/p to fit that setup, but good luck finding it. i think it came with the original drag kit. see if the guy you got the kit from still has it. but if he doesn't, it won't be hard to make. i think the d/p that came with that kit was only a 2.25" anyway, which is too small for turbo.

wats wrong with the vafc? (is it because u cant edit the ig timing) and i've got a p28 whic is chipped and i've got crome / uberdata (but i cant find an h22a stock map). plus the vafc seems sooo easy . umm.. injectors. if i am stay at like 5-8psi wont the stock 345cc injectors work just fine?? and finding a tuner would be kinda hard for me to do. i wrk 6d/10hr. so i cant really do that.

it just sounds like you are trying to squeeze your way into a turbo setup.....which is definitely not the way to do it. i know going with all the best brand parts is expensive, but it's really the only way to do it---and get your money's worth. i'm not hating on you at all man.....i mean, i understand where you are coming from---you want a fast car, but don't have a ton of money to do it with. that's completely understandable. but you are doing it a risky way, and you're engine will eventually show you that.

well if i was to use crome /uberdata would that be better for the motor than just the vafc2?

Yes, that would be a lot better, but you'll need to buy some bigger injectors like the ones that Chris mentioned and a larger fuel pump (if your kit didn't already come with one).

By going that route doesn't mean that you can load up a basemap and boost away though. You need to find someone who can tune it for you.

yes that manifold is a drag kit.. you would need to search around a bit at the different generations of the kits and find the one that has the manifold that is that size

you need a custom exhaust man. the stock exhaust is WAY too small in diameter, and you will lose TONS of power from using the puny stock diameter exhaust. you need a 3" exhaust, or at least a 2.5".
