100% stock s5 T2 about 10k miles, I'm going to do 550 and 750 injectors, rtec 2.1 ported waste gate down pipe full exhaust, intake filter with a heat shroud, and a fmic, with the throttle body mod and all emissions removed, walbro 255 FP, it will be stock turbo for a while.

 

enough to keep you happy for a month.

 

2 billion hp. But if you searched you have a basic set up. So I'd sayy 180-230 rwhp depending on the tune.

 

182-226 rwhp ;-)

What are you replacing the stock turbo with? Maybe a BNR stage 2?

 

what is horse? It all depends on how generous the 'correction factor' is and how the dyno operator is feeling that day. You can also have fun with the fuel calculator.

 

"What kinda power am I looking at?"
about 12 volts..if your alternator is spinning!.

 

I'd definitely say more than 180. 180 is stock hp.
Something in the low to mid 200s though is reasonable. You need more injector and more turbo to get higher than that.

also the throttle body mod and removal of emissions dont really affect hp at all.

 

Reading the first observation with:

550 and 750 injectors
rtec 2.1
ported waste gate (S5 turbo not as necessary as S4)
down pipe and full exhaust (just don't get short sighted and get rid of your stock cats for ever tightening emission situations down the road)
Intake Filter (CARB approved is your friend)
Heat shroud for doing your homework
FMIC (upgrade your radiator to compensate for resultant cooling issue due to air flow restriction)
Throttle Body Mod -- (moderate at best power value to tell the truth. I wouldn't do it unless it was defective)
all emissions removed (if you're going to make it primarily a track car , if your keeping it a daily driver. You just don't gain anything from a performance standpoint and DO gain a potential major headache down the road)
Walbro (Denso a better choice)
Stock Turbo (down the road consider a to4b that will mount stock including under the heat shroud to keep outa smog tech's view)

Bottom line, I strongly urge you to NOT be short sighted in what you're doing to a Bone Stock 10,000 mile (so very rare) S5 TII. I don't care what the smog check situation is NOW in AZ; it will only get worst going forward. And a low mileage car like yours, you need to consider resale value consequences.

 

210-220 to the wheels I would say. Depends alot on what the boost level is. 10-11psi I would guess with the intake and exhaust set up you mentioned.

Listen to Hozzman on what not to do. His advice comes from a place that is rare from most giving advice.... experience, wisdom, hindsight.

 

^ Thanks.

Case in point, an AZ guy looking to buy a TII. Read check is requirements:

https://www.rx7club.com/west-sale-wanted-classifieds-195/looking-clean-turbo-ii-have-cash-will-travel-972975/

If you're going to pull emissions, please just sell your car to that guy and buy a far more common high mileage TII and have your way with under the hood plans.

Sidebar, I'm putting 200 to the wheel with my S4 TII with S5 Turbo, RB RevII exhaust and FCD, drop in K&N, stock primary injectores, 680 secondary, Greddy Boost controller and AFCII running about 7-8.5 lbs of boost at max. I would not go higher boost with this set up as the AFC doesn't provide timing adjustment like a HalTech or the like would.

I'm putting 306 to the wheel on my S5 TII with FMIC, HalTech, about 14-15 lbs of boost, RB RevII exhuast, K&N cone filter, Aeromotive fuel system, and TO4B turbo. I got to 280 with the stock S5 Turbo.

In all cases I have all my under hood emissions in place. I just smogged my S4 at a test only. Passed. I smogged my S5 about a year ago at the same place, passed.

 

Well it's just the engine and tranny and wire harness, I'm going to drop it into my s4 drift car. And yea I was looking into saving up and doing the bnr stage 2 or 3 build with the new waste gate and then bigger injectors if needed. Now is the bnr turbo builds off of tje stock rx7 turbo or do you find and supply a to4?

 

if you are going to remove everything just skip the rtek and spend all your money on a haltech. then you can gain a lot of cash from selling your rare turbo electronics/harness on the forum.

 

Yea but haltec cost like over a grand doesn't it?

 

You get what you pay for.

 

There are members on here who have made gobs of power with an Rtek 2.1.

 

Very true, but in the long run I'm searching for 300-350 whp so I don't think a haltec is all so necessary to have, the extreme amount of tuning would be nice but that power can easily be reached with a rtec 2.1, injectors, and turbo upgrade

 

I believe RWHP is what was said.


RTek 2.1
720cc primaries
1,000cc secondaries
Walbro fuel pump
BNR stage 4 turbo
Racing Beat REV TII exhaust
FMIC or V-mount

You'll hit 300 just fine. (Depending on tune.)

 

So I was looking at the different lvls of the BNR turbo upgrades, and all that's needed is just the stock S4 or S5 turbo, and cash?

 

Yes.

 

Ty guys

 

if he plans on tuning it himself it will probably do, if he's paying someone to tinker with it by the hour it closes in on the cost of a real standalone with more room to grow real quick.

hell i'd say go with a PnP megasquirt over the 2.1, same cost and they have most of the bugs worked out of it now and has gobs more stuff to play with. no offense to the Rtek guys, i just think it was ill implemented with a basic palm pilot, low resolution scaling, tedious setup with limited growth potential(it quite simply hasn't been keeping up with the market). it reminds me of the microtech except with a hp ceiling of closer to 350hp but they're both carved out of rocks.

 

Go standalone. The rtek is good bang for the buck dealing with the stock turbo and dropping 720cc's in the secondaries (1.7), but beyond that you are getting it a grey area. An area that will have you wishing you would have just sprung for the standalone when all said and done.

When you go standalone you lose the restrictive afm, stock ecu, stock boost sensor.... you can get some cash back right there and you will never look back. BNR stage 4 can throw 400 to the wheels.... that is like 450 crank hp in an FC with a hybrid turbo. Again, 450 crank hp in a 2800lb car.... near stock spool, stock exhaust manifold, no external wastegate, no custom downpipe..... Stupid crazy awsome bang for the buck.

 

I didn't think they made a pnp megasquirt for the rx7? I know they make one for the miata cause my buddy has one. Any links on this or what pnp megasquirt works?

 

I suppose it all comes down to money... Do you already have the RTek? If not, do what Karack said... Go PnP Megasquirt.

I LOVE my BNR stage 4.

 

Nope nothing yet, I've been looking and reading a bunch off the forums and I can't find a actual plug and play MS? Is there one that comes close to and just needs a few wires crimped or soldered?
