running the twins non sequential how ?

4.5? a little bit excessive John, we were hitting 12psi before 4k(without a clipped primary wheel), even with the Apexi base map it was hitting 12 on 4k but I guess everbody maps differently.

I suggest you try a drag with a seq. set running the same power you will be left way behind, or try a bit of track work with that set up, unless you keep it in the power band you do struggle, this is only my opinion from experience gained running stock setup twins, non seq., mid sized single and large single turbos, I know where I would spend my time and money in the future.:Thumbs-up

For something being used as a daily driver and A/B road blast, mid-sized single is the best way to you do you think ?

Just been mailed about this so thought i\'d post.
I did a full non-sequential conversion on my first FD. This was the proper full conversion, and in my eyes the only way to do it.
This involves the turbo pack of and other supporting mods carried out.
By doing it the cheap way you will not see anywhere near the full benefits of going non-sequential.

What\'s the costs and extra work required ?

Ross has beaten me to my next question (possibly prompted by knowing the answer)................ John were you full conv? wastegate porting, flapper removal, Prim WG chamber welding and transitioning etc etc didn\'t find falling out of boost a problem, but im not exactly a track virgin either. lol

Devils Ref: cost me pretty much a new pair of twins (£350) as the secondary on my stock set was toasted when I bought the car porting work required a conical carbide cutter, which was free but they cost around £7, also a welder (from work!), a grinder (or drill and disc) and some blanking plates, I made mine, but you can buy them for about £20 I think.

Not forgeting the time taken running back and forth to work to do the modding and fitting, which was a couple of days to be fair and a few bits of skin that always get shaved but always seem to grow back on the knuckles.

[Shyne]

One other thing, if cost is an issue, then on a positive note, the bits you remove when doing the conv are all bits that Seq car runners need, sols, actuators etc so you can help some people with broken seq systems and earn back some of the cost at the same time, now theres handy! lol

Mine was a full conversion, call me picky but I just did not like the power delivery, boost came in one big hit and for me much to late and the dyno proved no more power than stock twins [within 2hp!] if you can afford it go for a single convesion, non seq. twins are more laggy:rolleyes:
Put it this way if you want to launch at 5-6k you will see a benifit but hay that is a lot of shock through your drive train:Hammer
As stated before it is a good way of getting rid of 2nd turbo blues but as a power mod personaly it did not work for me.
