Boost Designs: Anyone heard of them

[240KAT]

Does anyone know if their fuel rails will work with SR? I see they seem to be a KA specialist..but im sure about swapability of fuel rails and such.

Yeah, I've heard of them and plan to pick up there stage 1 turbo kit after I have my engine rebuilt. They seem to be a quality company. From what I understand the owner also owns www.ka-t.org.

Incorrect. Different people on KA-T.org. He is just the sponsor that sucks them off the most, and gets their own forums.
His stuff is questionable at best, in my opinion.
Search here for things I've said about them.. or even on my website, or NICO..
It's a good deal if you plan on getting every part of your kit, including exhaust from them. Don't bother trying to mix and match.

So, Jeff who or what would you recommend for a good ka-t project? I'm planning on having my engine rebuilt after I get my coilovers, but I was under the impression that this was a pretty solid company. Have you ran accross any other better kits? I did check out the ka-t faqs in the tech area, but they seem to be more of a mix and match diy system, but I might have to go that route too!!!!

[infinitexsound]

u can run theyre manifold and ditch the dp and have one fabbed instead... its just better this way because u wont have lining up issues plus u can use a flex pipe for insurance..

as for building motors.. hmm i say do it your self buying a crate engine is nice if u can afford it... but building it your self will definetly be a little cheaper.. plus its on ur schedule...and u learn some skills while doing it and researching...

i still think their fuel setup is pricey cause i built one similar for 1/4 of BD cost...

ya, definitely not the same people. lol

but anyways, i used the exhaust manifold on my car and did a few custom things to make it fit with my previous FMax intercooler setup. i used a different turbine and wastegate flange so i really didnt use anything from the kit except the manifold and downpipe without flanges. the manifold has worked out fine for me.

I'm running the FMax intercooler/piping on my BD manifold also.. I just cut a 2" section out and got a 90* silicone connector.

The guy above Ryan was right on the custom downpipe. I made a post called "what's necessary to swap the flange on the BD downpipe".
http://jeff.obhost.net/filestorage/turbo/pic221.jpg

That's just the flange, because they use some Mercedes turbo with a Mercedes 5-bolt flange, and not the aftermarket standard ford 5-bolt flange. So that's 2 spacer rings fabricated, 1 ATP flange, 1 ATP 2.5"->3" expansion, 2 more O2 sensor bungs because one becomes worthless later. Then cutting the dp in half at their weld, flipping the dp, adding spacer rings, and a ton of welding. You can see them all. Now, my wastegate isn't fully lined up to perfection, so I need to grind off ~1/2" of ceramic coating from the dp dump tube and cut/weld it back together so it's spot-on.

Then.. it doesn't mate with an sr20det downpipe. Now.. I like using the sr dp because it's 3", and requires less pipe routing (imagine snaking a 3' pipe through the steering column/tranny, ect. But they terminate at the end of their own exhaust. Proprietary again. So to fix that.. I hacked up my sr dp.

http://jeff.obhost.net/filestorage/turbo/dpside

You can see another spacer ring, the flex section, and some creative cutting/welding on the sr dp to work with the BD dp.

So ya.. many hours of work and welding there. If I'd have known earlier, I would have made my own dp in less time and cheaper.

Next up is the fact his stuff is getting a) more expensive and b) longer wait time. A) His cometic hg was $80, now $100. PhatKA-T went just the opposite. B) I know people who have waited 3 weeks for a fuel kit.. and when he emailed them.. the reply "IT WILL BE A 3 WEEK WAIT, IT SAYS SO ON THE WEBSITE." First.. don't yell. Second, it says 3 weeks for turbo kits. Not a crummy fuel rail and some lines. And ya.. it's a crummy fuel rail. There is a discussion on it on NICO.

I don't want to badmouth the guy. I'm happy with the manifold or I wouldn't have bothered dicking with the downpipe.. I would have sold the stuff to some other unlucky sap. But when I said.. "You know. I've had a turbo 240sx long before you knew what a 240sx was. I know what people want.. and proprietary isn't it. It would be mere hours to slightly adjust the downpipe to work wiht an sr20det downpipe. Change flanges at the shop, not sell these things individually knowing full well they won't work on someone's setup unless they previously bought the whole kit sans the downpipe (which he doesn't sell)." That's shady business to me. Selling someone alone you know won't work?? Come on now.
Just like making a 240sx exhaust that doesn't terminate at the end of the cat. His exhaust isn't a cat-back, and WILL NOT WORK ON NA KAs. You need a extension pipe made to meet with the stock header. If you have an aftermarket header.. the BD WILL NOT WORK AT ALL. It's stupid, see?
I always got a cocky answer. "I spent hours dyno testing and flowbenching to ensure maximum power". Ya? Where are these dynos? What is the before/after? How much gains were necessary to be such a hassle to customers? "Well.. the KA and SR are very different motors!" Bullshit. Both are turbo, both like to breathe. A 3" pipe is a 3" pipe. His exhaust makes the most power? Oh ya? With that slip-fit in the middle of it.. hmm.
How many people plan to go KA-T and need an exhaust? I didn't. I had my Dual N1 before ka-t plans. And.. when I switched to ka-t version 3, I still had the n1 dual. But.. his downpipe makes it necessary to buy his exhaust.

I'm just sick of dealing with these pieces because nobody (including him) warned me that these things were SO FAR off of the norm. I mean hell.. my topmount revhard and t4 used FMax (sidemount and t3/4) intercooler piping. There is a norm for a KA.. and he missed badly.
I'm also sick of his ever increasing prices. The ever behind schedule parts. The poor attitude on his posts. The disgusting spelling/grammar issues. And most importantly, bieng told that his stuff makes the most power without any proof. Even PhatKA-T put up their 633rwhp dyno sheet/video. Their stuff makes the most power.. Boost Designs needs to put up or shut up. They need to have things that work with other systems. Or how about that Intake Manifold from Boost Designs that has been bieng installed and dynoed for the past 4 months??

To me.. it's just a bullshit company run by a bullshitter. Corners cut, costs cut, lies, dangerous fuel rails, ect.

yeah, i was planning on getting a BD kit a while back, but then i started looking at their stuff and easily figured out it wouln't work with other things (specifically the DP). So i said fuck it and started peicing toghther my own setup for wayyyy cheaper that their stage 1 kit. I got a t3 super 60 for 200 bucks and a top mount RH mani for 200 bucks...can't beat that! BTW, will an SR down pipe work with that rev hard mani and a t3 or will i have to fab up some custom shat?

[Jeff240sx]

You still need to fab up a downpipe from a topmount.. but it's much easier to just aim for a sr20det downpipe. You just end up needing a 90* bend and slight (30* or so) bend around the steering shaft.

As Jeff said, I wouldn't touch their fuel rail after his little "quality control" mishaps. And the way he handles himself on ka-t.org and through other forums is less than impressive...

[infinitexsound]

ok jeff some venting... done... yeah i did like them when they first came out... but after just researching and being the DIY type of guy i said screw it... i was gonna buy their manifold until u posted up that picture of how things lined up... obviously my mind changed, proprietary is true...for the main things...

i cant still believe their charging so much for the fuel setup when i paid 1/4 of the cost...

what numbers are u getting with ur kit jeff?

I don't have dyno numbers. I am having a boost issue. My old tial 35mm at 6.5psi on my revhard/t4 made solid 6.5psi. When I switched to Boost Designs/sc50 (t3/4), using the SAME wastegate, SAME spring, SAME vacuum source, it made 10psi. Figuring "Ok.. BD uses a generic 38mm gate, so I will too" I bought a tial 38/40 hybrid gate to hold boost solid, at 10.5psi spring.
Well.. I had to let off at ~60% throttle because I was making 14psi. With 50# injectors currently.. that's unacceptable.
I still haven't figured out the boost issue...

Holy carp!!one1!! I didn't even see there was a question about the rail.
SR has different injector spacing.. and fuel rail mounting points. Can't use a KA rail on SR, or vice versa.

[infinitexsound]

cool deal good luck with that man... project silvia fuel rail and use denso style top feed injectors "t2"..<gonna have to machine very little off . buy new clips and wait for a good price aeromotive fpr .... all together probably around $250.. but i waited and waited and got mines total for $150...it works to be patient.... well see when my motor is done... ill post the facts and dyno sheet on ka-t and here...

[raen419]

a local guy i know (keep in mind i live in b'ham, AL) has their stage 1 kit on his hatch, he loves it. not sure how long he's had it, but from what he's seen, and heard from other people, they're a quality copmany.

[sideview_180sx]

why not hit up jgycustoms.com or some other sites that sell SR fuel rails.

[bing]

i havent dealt with boost designs at all, but i havent heard anything bad until this post.

i do recognise alot of their stuff as being taiwanese or chinese products imported over here, that is not necessarily a bad thing.

WRONG.... not a big fan of boostdesigns myself.... but to clear somethings up... there shit is not imported... its made here in the US by a company called ATR.... atr knows there shit... they been messing with turbos before some of us were even born..... well... the younger people... some of boostdesigns shit is questionable.... like the wastegate and bov.... dont know too much about that.. dont even think its ATR.....

i dont like boostdesigns much at all... but i had to clear that up....

[bing]

yeah i was speaking specifically about the BOV and wastegate.

i would imagine that some of the IC's and other components of hte kits are imported as well.

alot of companies design their products here and outsource the production overseas.

i dont know anything about ATR so i cant comment on that stuff.

[Jeff240sx]

ATR works on GNXs...
