non seq is not worse than sequencial, just different, though less complicated which in some way means more reliable.

as for getting your stockers rebuilt, most big rx stores offer it, ex. -rx7store.

this is really popular info so search around the forum for non sequencial and where to rebuild turbos.


as for 400rwhp... you'll probably need rebuild or a single turbo. a strong engine of course. an ECU such as PFC. Fuel injectors, pump, regulator, possibly a fuel rail for the new injectors. a bigger intercooler. of course you'll want all the normal things like nice aftermarked radiator, AST, intake, downpipe, catback. probably will remove the air pump and main cat too if emissions aren't a problem. If they are, then that's another issue.

it just makes it so there is no boost spike, they spool up at the same time

you need at least my mod list with the bnr twins...as far as proven 400rwhp. I will have my dyno sheets in the next day or two and am hoping to hit that same kind of power level with the m2 set. different turbos have the power at different times. the m2 set currently offers the most power down low as they are dual ball bearing and put on full boost by 2800 rpms. non seq stockers usually put down full boost by 3500-4000 rpms in contrast.

non seq is very simple and will save you headaches...however i swapped to non seq at one point and found it to be too laggy and i didnt enjoy having to speed into the upper rpms in order to relish the power.

bnr is or m2 or TEC r the only places that i would deal with regarding rebuilt turbos. Ive had two sets fail from other companies like turbo city and performance techniques.

wargasms dyno site is very helpful in seeing what turbos do what in terms of power output and placement. check the most recent m2 upgrade thread of mine for the link...or do a search in wargasms posts.

Thanks, for the info...
I was reading on ebay that a guy was selling someturbos and that that non seq gain 30+- hp because they both kick in at the same time, is that ture?
........what about going single? is that what i should be doing

particleeffect

Both single and non seq are less complicated and atleast in single's case, almost always offer more top end power. At a cost of a little bit of low end power. Use the search for more info.

artguy

non seq takes away power down low...and puts it in the middle of the powerband instead.

its simple...efficient...and too laggy for my tastes.


if you are going to upgrade your turbos you need just about everything in my mod list.
