turbo ka downpipe options?? help me out

[reed1285]

whats up...new here. im a member of 240sxforums.com also and asked this same question on there, but it takes an act of congress to get some help on that site for some reason, so i thought id ask here. ok im fixing to put a new exhaust on my turboed 95. what downpipe options are out there for me? the one on there now is custom, and its welded to the catalytic converter, then the other side is welded to the rest of the exhaust pipe. i dont like this cause the guy who did the custom work made it to long so my exhaust pipe hangs dangerously close to the ground. im looking for a good downpipe so i can bolt the cat converter on instead of having a completely welded up system. but im not findin crap yet, everything is for a sr20. ive heard that you can use a sr20 downpipe with some modification, is this true? and what kind of modification is needed? or where can i get a downpipe made for the ka. thanks and any info is GREATLY appreciated

you can use a sr downpipe i believe just fine... i used a sr megan downpiple with a flewpipe added to it but had to add a 2'' extension to it since the flex pipe it the firewall

You will have to have a new DP built for your particular ka-t set up and your current exhaust modified so that it fits to your liking. I would not recommend just buying a DP designed for an SR to try and bolt into your KA-t set up as you will wind up needing to modify at which point you may as well just have a new one built.

information such as:
turbo/turbine housing outlet design
manifold
would be needed if you are hoping to just buy a DP however it sounds like your current set up is not going to accept a new DP with out some cutting/welding/fabricating

What setip is your Ka-t? Topmount or bottom mount? If it's the bottom mount and you have the typical t25/t28 turbo then you should be able to run an SR downpipe with no issues. Any five bolt one should work.

sorry guys i shouldve been a little bit more clear on my setup. im using a precision t3/t4 .60 trim, on a top (more like side) mount cast iron log mani (car still has ac) the tial wastegate im using is also dumped into the downpipe, i know that whatever downpipe i get i will have to do a little work to it just because of the dumped wastegate, i dont like them open. ive found one made by xcessive manufacturing that looks pretty good. its designed to be used with their top mount manifold on a ka....i wonder how well it would fit my setup? thanks for the input...oh and its the 5 bolt turbine housing

By far your best option is to have someone who knows what they are doing fabricate something for you. Nothing else is going to fit correctly, coming from a fabricator i would much rather start from scratch than try and work with something that may not even come close to fitting.
I would say do your best bet is to find someone in your area that can tig weld stainless (perhaps even a hot rod or other performance shop, diesel, motorcycle) if they don't have material call email my former co worker and ask for the fallowing. [email protected]

2 90* 3" SS bends
3' of 3" SS straight
2 90 1.5" DIY dump tube (i'm assuming you have a 38mm gate?)
1 dump tube flex section

This will get you everything needed to have someone build you a very good DP/wg vent. Wont be super cheap but you won't have to do it again.

Cheap option say fuk it, take it to a diesel shop or other exhaust shop and tell them you don't like how low it hangs and you want it flanged by the cat so it's 2 pc. i'm sure you can get some (for lack of better term) red neck fix for around 200 bucks ;)

good luck (thinking more on it go the cheap route for sure, no reason to invest in a super nice DP when you may end up changing out the manifold or turbo in the future.)
