Non-Sequential does not add HP, just changes the power curve. ArtGuy and CaptBill are both running sequential.

I'd imagine the M2s running parallel would be like running the stockers non-sequential as far as spooling goes. Probably have full boost by 3200-3400 rpms. Not many people have these turbos since they are $$$ but artguy seems to say they put out some power - no dynos yet though.

Rikki, curious as to why on pump gas you think 365-380 is the limit? Are you talking about running the M2s atthat or that much hp on any FD? I'd think the M2s could put out decent hp on pump gas.

Actually, if done the "right" way, going non-sequential does increase hp. That's a full conversion where the restrictions in the manifold are removed. Talk to www.n-tech.net about it.

still the idea sounds a a bit queer,,,, i mean the original set up may not be the best but still, they were ment to be sequential i mean ones bigger then the other, running at the same time just aint right. IT AINT RIGHT!!!

RX-7 twins are the same size. Cosmo twins have a larger secondary.

i considered it...but I dont think you will want to...the quick spoolup is a blast and it definitely shows its strengths when racing other cars running non seq and similar boost.

non seq = LAG....LAG SUCKS ***!

quote me on that.

thats why i went with the m2 set....spoolup and more power in all ranges (not single turbo power but not single lag either)

if you want a car for the street the m2s running seq in combo with a streetport is the way to go IMHO.

hopefully will have the car dyno charts/tuning done soon. Dave at KD redid my maps and is sending them to me tomorrow. My car gets out of the paint shop on Friday...then its just a money thing til it gets done on the dyno...soon.

I also need a diff map sensor as well...the stock sensor only handles boost to 16.3lbs..after that yer farked. Doing all this is a learning experience...it seems like the list never ends.


goracer...we should meet up after my car is tuned. they started having those "saturday night car gatherings" we often attend in SD, up here in OC. Im wanting to check it out. There is a certain rich kid with a newer supercharged M3 who is lookin for a spanking from a black rx just like mine ...maybe it will be the rx that sees tail lights...we shall see.

rikki...do you think an upgraded ignition system/fuel pump/ injectors would allow for more hp than you suggest is safe on pump gas?
