60-1 & 62-1 club!! post if you have one
Yes! I finally get to join.
62-1 with a .96 hotside newly rebuilt with the big shaft option with gold back plate.
Heres a list of mods.
1987 S4 Turbo II
S5 Turbo II motor and trans.
Street port
HKS Light weight flywheel
ACT clutch
Racing Beat Rev II exhaust
Racing Beat FCD
720 CC secondaries
Greddy RS BOV
Power Steering, Air pump, Cruise control,and AC Removed
ACV EGR valve Block off plates
And these are the parts sitting in my living room lol.
Turbonetics 62-1
XS power Manifold
HKS External wastegate
Microtech lt-8
Greddy Front mount
Walbro 255
RC 1600CC injectors.
Trying to get everything done in one shot.
What kinda power do you guys think i'll get?
Also am I missing anything?

Thanks Brian 
Its progressed a bit further then this now as well.
Am finishing off my twin plate install this weekend then hopefully off for a tune (shortly... but dont know).
Unfortunately where I live Mircotech's are the most comment ECU. So Ive only found one reputable guy to tune my haltech... I believe his still out of the country so might have to wait a bit...
lol only wish I could get someone with your skills down here for a tune

[QUOTE=arghx;8072960] Stock FD has 550/850, and there are people running 850/1300 on the stock lines and rails, which is enough injector for 400rwhp.
I'm relatively new to the rotary and I'm bewildered on the injector sizing I'm seeing. 2x850cc/min + 2X1300cc/min = 420 lbs/hr fuel flow. That translates to 630 HP @ the crank assuming a reasonable .60 BSFC and .90 DC (420*.90/.60). So is that 230 HP being lost on the drivetrain? 630 HP seems like quite a demand to be placed on the 1.3ltr for any period of time specially without ceramic seals.

Rotary engines don't consume fuel the same way as pistion engines, (short answer, they like more). Additionally, detonation = death, and to keep afr's low many (I would almost go so far as to say most..) tuners dump in more fuel which neccesitates larger injectors, becasue they are also not fond of running more than 70% duty cycle on said injectors. Which leads to the injector sizing you have witnessed.
Its always fun to tell my piston engine friends about my fuel system upgrade plans, I could build a house from the bricks they've shat...

eh??
its pretty explanatory i thought.
anyway, i dont care about big hp or big turbos. i wanted a peppy car that would make girls cream their panties from exhaust note alone. 20b can do that in almost stock form, but... i had some problems with the stock twins.
first of all, they are heavy, ugly, and complex.
so i could try to do 1 of 3 things. run simplified seq, run parallel, or go with a relatively small single.
second problem that arose that brought me closer to single turbo, was the fact that i didnt know how to do simplified sequential and after talking diligently with many people that are more knowledgeable than i, i realized that i was not going to get a fast spool with the stock turbos in parallel. the best i could hope for was full boost by 4k, maybe 3500 if i clean up the cast manifold. also, while debating and arguing (always losing) with myself, i pulled the stock turbos off the motor to see that the primary turbo had oil all up in its face and compressor tract, leading me to suspect a blown turbo.
so scouting, more questions, deliberation and phone calls led me to decide on the 60-1 as my turbo of choice.
i know that i will get resistance on doing this since 20b single turbo cars are decided by the community to all be at least 500hp or be considered failures but low hp is my goal.
even guys at banzai said i was an idiot for going with such a small turbo. nobody understands this. i dont understand why they dont understand me but ill have fun anyway.
my goals as defined: 350hp +/- a few @ 10psi, full spool before 3k rpm. low heat, little strain on engine and badass sound.

I believe it will work exactly as I intend. The hotside is big enough for it to not die too bad and I need spool as early as possible for my intentions.
Either way, ill find out how things work soon enough

i called the company asking where the hell my turbo was. been waiting for it for 3 weeks. turns out that they ran out of stock and arent getting any more in so i got a refund. ordering a .96 hotside t72 from rotary works on friday.
and just like that, im out of the 60-1 club
