If i was you i would do it, non sequential w/ 99 spec. They put out more boost equaling more hp. With help of bolt ons and a pfc im pretty sure you would get alot less lag. I have a non sequential and going to do just that. Later once my turbos start going out i will put in 99 spec's or BNR's.

 

Well, I'm truely sorry that you feel that way, but you are honestly reading way too much into this. First, I never stated that upgraded solenoids were a new idea created by me (I first started looking into them about 2 yrs ago, and there were a few others that had done so long before me). I never sidestepped any question. You asked where you can buy them, and I told you from me. Although there are several companies that offer off-the-shelf solenoids (and I'm sure you can find some that are very similar to the ones I use), the operators that I use are built to my specifications. I gained distributor status because I could get all the components at a much cheaper price (which includes decreasing taxes somewhat) and supply them to FD owners at a LOWER price then they could get on their own. As I stated before, I increased the price only enough to help defer other misc costs. I made basically nothing on the sale of these (and that is the cold-hard truth). Shoot, I got tons of e-mails from individuals asking for help and recommendations. For various reasons, I recommended to many of them that they just keep their stock solenoids (for an example, just look at post number 18 in this thread where I recommended to herblenny to just use his stock solenoids. If I was only interested in making money on these, then I would have fought my hardest to take him in as a customer).

I make plenty of money in my other jobs, that I have no desire/need to try to make a small profit off of something like this. If you think that my primary motives were founded on nothing but a desire to make a buck, then you obviously don't know me very well.

Good luck,

No, I do not know you, and I am sorry if the assumptions I made are incorrect. I can only take situations at face value and interpret them to the best of my ability unless everything is explained and laid out in front of me. And from my interpretation, everything was addressed and then some except where to purchase the solenoids. If they can be made to your specifications, why would they not be able to be made to any other's specs? That was my only qualm.

 

Sure, they can be. But why? The whole idea is that there really is no point. I've already gone through the trouble of developing/designing/specing them, and have jumped through the hoops necessary to obtain them at a distributor's cost. All in an effort to help out a few FD owners get a system that would otherwise be a complete waste of their time to build on their own. If you don't want to take advantage of that, and you would rather design and build your own system, then go right ahead. This is no different than those that want to build their own VMIC, or engine mounts, rather than purchasing pre-fabbed parts. But IMHO, that DIY mentality coupled with some incorrect assumptions is really no reason to start flaming another individual.

Take care,

i will be using 99 twins in non sequential mode when i have finished my rebuild. only reason for it is to get used to the lag of a single cause i'm converting when the funds build up again after the rebuild bill oh and the turbos were free with the car - theyre not that hard to find here in aus :P

 

Dude, the thread is years old...but good luck with the build...

 

said it like a champ!!!!!!! learn to fix your damn FD's people and know what the hell youre getting into before wacking the beauty into a beast!!! IMO stock setup is the only way to go far as a "daily driver" fd goes.

 

I ran my 99 spec turbos non sequential. It was the worst think i ever did to my car. My sequential was working perfectly. I wanted to try it because the 99s were suppose to spool faster, so i thought the non sequialtial lag would not be that bad. I almost went the full non sequential, but i decided to put it back to sequential. I was much happier with the sequential system.

One thing that no one ever mentioned was that the car will be a lot louder with the non sequential. My car was really annoying at freeway cruise. It was hurting my ears, but it was fine when it was sequential. I was running a down pipe, high flow cat and pfs exhaust.

 

If you want to run non seq... just go single and limit the boost to 9-10psi.

otherwise, fix the sequential system.

You lose much more low end versus what you gain in the top end.

 

or if get tired of always fixing it . I had a perfectrly working sequential system started crapping out on me. Replaced all the vacuum lines worked fine for about 3 years. Then about avery 3-6 months a problem would surface. Deal with that for about two years so I decided to give non-seq a try.

Verdict: bah, lag and boost threshold really sucks but it was really nice as far as reliability.

 

i never undstand why people want to go non sequential.

I mean you build boost instantly when sequential on the first turbo, then it switches to using both turbos anyway higher in the rpm range.
Iv never driven a non sequential FD but i can never get my head around why you would want to get rid of the instant boost in favour of no boost untill you would usually be on both turbos anyway?
to me it just seems like it creates unnessacary lag with no benefits other then the possibility of better gas milage and a more simple system
it seems by the time the non seq guys are building boost, a seq FD would already be hauling *** and long gone.

 

Hey Rob, are you still making the solenoid kit?
If so how much? Do you have any current pics of the kit?
Thanks

 

Just downshift...that's the key to non sequential.

 

Why the hell would you spend 3k on twins...... just to run the non seq? they are less efficient all around than a single... and you can run a single at low boost all day and make more power than the twins due to efficiency, charge temps, etc.

buying 99 specs to go non seq is pointless. just buy a single and be done with it.

The key to non-seq is fixing your sequential system.

 

Who the hell is spending 3k on twins?

 

From the first post:

Need I say more?

 

99 spec twins are NOT 3k. For this amount of money, you should go BNRs instead since it's cheaper.

Oh, sorry... 2600. lol

My point stands. Thanks for the $400 correction when we are talking about new turbos here.. with the BNRs only running $2350. (I know this for sure )

 

Why the hell would you want to go through the headache each time you have a boost problem and trying to diagnose all those vacuum lines

 

my 99 spec twins came with my car for freeeeeeeee

 

Great, so now you want to run the equivalent of an INNEFICIENT single?

Seriously. You have 99 spec twins. run them sequentially. Non-seq IS NOT a faster car. Yes it requires you to learn more. Yes it requires you to use your brain more. No, it is not faster in 99% of driving.

No point.

 

Why the hell would you want to make your car slower in 99% of driving situations?

Seriously, there is no strong argument as to why to go non-seq.

pro non-seq:
Less troubleshooting
Less knowledge required

Against nonseq:
slower 99% of the time on a street driven vehicle.
low end suffers

Against Seq:
Required to learn more
Required to know your car better
Required to more troubleshooting IF something goes wrong

Pro seq:
How the car was designed.
faster in 99% of driving
Friggin fun!

Really dude. I mean... Really?
