Boost Boy-->?'s about Ur SDS

[float_6969]

Hey, I was under the impression that you have an SDS unit. I wanted to know if I could ask you some ?'s about it. My main ? is whether you used the stock coil packs or used their ignition system. If you did use the coil packs, do they seem to fire well being run in pairs? I would think that in the higher RPMS the smaller coil size would have trouble with recharging. I wish you could sequentially fire the ignition. I don't really care about sequential fuel injection, but I'd rather keep the coil packs if I can. My max power goal would be 300hp, but I'm more concerned about a broad powerband than anything. I'm autoxing and I'll need it. NEway, I just wanted to hear your opinions about it being used on the CA. Thanks!

boost boy, doesnt use the Nissan coils he uses the coils and plugs from SDS, he says after 18 psi the stock nissan coils dont work well , forget the word he used, the SDS is a batch fire Ign if i remember correctlty. goin for 300hp you could prob get away on stock IGN and Emanage, and maybe just Eprom tuning instead of goin full standalone

[float_6969]

the batch firing is the ONLY thing that I don't like about the SDS unit. And I don't even care about the batch fired injectors, it's the batch fired ignition that bothers me. I want the tuneability a standalone provides, but I don't think I need THAT much tuneablitiy. Is there a piggyback that will adjust fuel & igntion both?

[boost_boy]

Most standalone systems are batch fired and the stock CA18DET coils are good to a certain extent and can support 300hp, but I was looking for a chance to toss them and the SDS system gave me incentive. If you're autoXing, a system like SDS would be instrumental to have because of tuneability/adjustability as opposed to piggy backing. Why do you care about how the system is fired, when reliability and performance are the main concerns. Just ???s I'm asking you about what you want and what you need. I mean for the money spent on an SDS, it will have surpassed the performance of an emanage or other piggy back system. I'm not knocking them, but I'm very comfortable with the system I use on my cars and what I install for my customers. They love it and have no problems with it and so do I!

hey dee, i e-mailed you yesterday but dont know if ya got it yet. im me sometime or e-mail me back about it. thanks

Hey Ian,

I got your message and still do have you in mind. Regardless, I will still be able to get you a system at a competitive price.

[float_6969]

Well, guess I should ask if I really need that much tuning capability. I'm not afraid of it by anymeans, but I certainly don't want to purchase anything I don't need. At max I'd be going for 300hp, and I prob won't go that high. More intrested in a wide powerband and quick spooling than peak power. I think that 250hp is a more appropriate #. My reasoning for wanting to use the stock coils was for 2 reasons, first, I didn't want to purchase a new ignition system if I didn't have to, and secondly the 'cool' factor of the coil packs If this is any indication, I don't plan to go into internals, except for a headgasket, and MAYBE oversized pistons, but that is more for displacment than the strength increase. If I do I'll prob cryotreat and shotpeen the rods, just cuz it's cheap and I'll already be in that far. But thats a long ways off. Anyway, I guess I'm not intrested in standalone if it isn't required for my needs, but if it would be that benificial, then I have not problem with going that route. SDS would be my first choice if I were to go standalone. As far as the batchfiring, it's not that I have a problem with it. But with the smaller size of the stock coilpacks, it doesn't allow for a lot of time at the higher RPMs to recharge. I guess, I just kinda want your opinion as to whether I need standalone for my goals. I know that I don't want to have anything to do with ECU retunes, that's just silly in my opinion. Thanks for you input. BTW- my name is Ryan.

i hate to sound like a dumbass but what exactly is SDS? I know its a standalone system but is there anywhere i can find more info on it? Like a company website?

[slw240sx]

its simple digital systems, boost boy has a link for them, ill post it if i come across it in a min

[boost_boy]

Hey Ryan,

Unfortunately, the standard coilpacks will go bad sooner or later and can get expensive buying them from nissan because of their scarcity. If you're looking for 250-300hp (I'll assume this will be at the wheels), be prepared to toss those those stock injectors or use additional injectors because the stock fuel system will be out of gas at around 230whp (if not sooner). The stock T25 will be on it's face after about 13psi and anything after that is flirting with that turbo seal failing. The factory ECU will need modifications or need assistance from one of the little trick-boxes (ie S-AFC, VPC,etc) that in my opinion are designed for someone who likes the lok of multiple equipment in their car. Standalones standalone in the fact that they do their own thing. The SDS http://www.sdsefi.com will handle all your tuning needs via an LCD programmer as opposed to using a friggin' laptop. With an untuned SDS, T3/T04B stage 1 turbo and MSD 50lb/hr injectors my girlfriend's car put down 286.1 whp and 235.2lb/ft of torque @14.7psi of boost. Just an idea of what the system is capable of assisting you in achieving. That T3/T04B stage 1 is a quick spooling turbo that will get you going really quick and efficiently.

[float_6969]

Thanks Dee, that was the info I was after. I had every intention of upgrading the injectors. What duty cycle were the 500cc injectors running at that output? Should I spend the money for a BB turbo? I'd like to use as small as a turbo as possible, but still stay within it's effeciency range. When did that hybrid reach full boost? Is it tuned now? What kind of #'s are you putting down if it is? I'm VERY familiar their site. I pretty much have it memorized. I dreamed SDS for a full week after I first went to that site! How did you mount the HALL sensor? did you just use some of the timing cover bolts? I think that would be the hardest part of the install. I don't have acess to any machineing equipement, so that part would be hard for me. Well, I guess, I'll have to replan my upgrade path. Regardless, that is a ways off, but first hand info was what I was after. Thanks!

i just got a chance to look at that site and damn is that thing expensive! oh well. back to work for me

[/quote] You would rather pay JWT $600 to do your ecu, $200+ for an AFM and you'll have to give them the type of injectors you plan on running so that they can program the ecu to run it! I don't see where it's too expensive at! You're paying for the opportunity to not only tune your own car, but to have full flexibility of any mod that you install. It's no expensive than any other standalone system out there, but more simpler. And yes it works! Would love to race another CA powered or SR powered vehicle that carries the JWT remapped stuff! Oh yeah, I've done that already and won over and over and over again. I owned 4 of these sytems at just over $1300 each; sold 2, put 1 in my girlfriend's car and have yet to use the last 1 and I'd do it over again.

[iliketocrash]

btw. where'd you buy your t3/t04b stage 1 turbo from?what turbine a/r did you opt. for and did you by it internally gated or do you use an external. i'm asking because i'm doing a comparison to find the best turbo i can for my somewhat limited budget.

[CA18Fastback]

dee, can you e-mail me soon. i really need to get an SDS from you ASAP.

Thanks!-Ian

SDS is a favorite with guys down south it seems.... they work wellIf you have big plans down the road, its a good building block, but for 300hp, it might be overkill.Some of my buddies run sds, and say the system is "injector hungry". They like 'em thoI know of people running great on imported systems, need laptop, but very good display, compatible with lotsa oe triggers, coilpacks, etc. price ~$700 landed. I'm getting one for another project

Go to the uk or aussie sites or even freshalloy, and copy a 250-300whp combination. CA or SR, doesn't matter, they both put out the same with equal mods;z32 mafs + 444cc injectors + chip (or piggyback) + T28 + fmic / pipes + 2.5" exhaust.... have already put down 280-340whp depending on tune.. very responsiveNo need to waste $600 at jwt

[Oneor1]

Hey Dee, I wrote you an email a day or so ago about those IM parts.... that we talked about a while ago..... do you still have em? let me know cuz im ready if you do..... Later man

Hey Rick,

I'm ready when you are!
