Thats not even English 

I'm a full ching chong bing bong and my engrisher is better LOL

We sponsored topstages S14 for wtac this year, its an built sr20det with solid head and pro cams. Upgraded to our ATR43SAT turbocharger from Garrett GT3071. Car made more power through out the whole rev range and maxed at 381rwkws e85 fuel.

Haha, the car had upgraded fuel pump later on so I upsized the turbo to an ATR45SAT which made 408rwkws on an aggressive tune. Backed to 399rwkws for tracks. It run 1.251 at Winston last week beating previous wtac winners result of 1.26

I think 420rwkws is about the most this turbo can do. have to upsize wheels for more power. But Its plenty for what this car needs so far.

Hi all.
I'm about to order the atr43sat for a 25. Looking to make 450-500rwhp Questions are:
Can that be had internally gated through standard dump?
If I need to change dump etc might as well go ex-gate yeah?

Speaking of Non VCT, low cr engines, did you ever end up doing any development with an RB20 Tao?

There are so few of them around and took a while to find the right car. Picked up a 93 model R32 GTS4 in good mechanical order. Will be starting developments based on R32 Rb20det engines. My goal is to 270rwkws on pump 98 fuel with good turbo response.

Car is pretty basic with a return flow cooler, and a turbo back exhaust fitted. I will be Nistune it and drop in some ID injectors for starters. I will list prices and places as project move along.

haha true, my plain is to drop in a RB25det NEO motor off a Stagea in it later on, Nissan should've done that years ago.

I will be using our ATR43SS1 as well as doing some high flows, and see if there are room for improvements.

Will be moving to a new ATR45SAT Ball Bearing soon.
Will put results up here once dynoed.
Below is what im going from -> to.

ATR43SS2+ gate off housing - > ATR45SAT BB
Stock ExhaustMani - > D2 Stable High Mount + Gate of mani
44mm Tial Gate - > 50mm Turbosmart Gate
Stock Plenum - > Custom FFP + Sard Fuel Reg
Single 460 Walbro - > Probably Surge tank
Nistune ECU - > Adaptronic ECU +Wideband/Airtemp sensor
Z32 AFM - > MAP inside adaptronic
E85 - > Still E85
Stock Head - > Only doing ARP headbolts
And a bunch of other random stuff

Was ~450 hp at the rears - > Hoping for + 550 hp at the rears

Current full boost is around 3800 @ 20-21 psi
Im hoping for similar response, looks like it will be close.

    • Had I known the diff between R32 and R33 suspension I would have R33 suspension. That ship has sailed so I'm doing my best to replicate a drop spindle without spending $4k on a Billet one.
    • OEM suspension starts to bind as soon as the car gets away from stock height. I locked in the caster and camber before cutting off the kingpin. I then let the upright down in a natural (unbound) state before re-attaching it. Now it moves freely in bump and droop relative to the new ride height. My plan is to add GKTech arms before the car is finished so I can dial camber and caster further. It will be fine. This isn't rocket science. Caster looks good, camber is good, upper arm doesn't cause crazy gain and it is now closer to the stock angle and bump steer checks out. Send it.
    • Pay careful attention to the kinematics of that upper arm. The bloody things don't work properly even on a normal stock height R32. Nissan really screwed the pooch on that one. The fixes have included changing the hole locations on the bracket to change the angle of the inner pivot (which was fairly successful but usually makes it impossible to install or remove the arm without unbolting the bracket from the tower, which sucks) and various swivelling upper arm designs. ALL the swivelling upper arm designs that look like a capital I (with serifs) suck. All of them. Some of them are in fact terribly unsafe. Even the best one of them (the old UAS design) shat itself in short order on my car. The only upper arm that works as advertised and is pretty safe is the GKTech one. But it is high maintenance on a street car. I'm guessing that a 600HP car as (stupidly, IMO) low as you are going is not going to be a regular driver. So the maintenance issues on suspension parts are probably not going to be a problem. But you really must make sure that however your fairly drastically modded suspension ends up, that the upper arms swing through an arc that wants to keep the inner and outer bolts parallel. If the outer end travels through an arc that makes that end's bolt want to skew away from parallel with the inner bolt, you will build up enormous binding and compressing forces in the bushes, chew them out and hate life. The suspension compliance can actually be dominated by the bush binding, not the spring rate! It may be the case that even something like the GKTech arm won't work if your suspension kinematics become too weird, courtesy of all the cut and shut going on. Although you at least say there's no binding now, so maybe you're OK. Seeing as you're in the build phase, you could consider using R33/4 type upper arms (either that actual arm, OEM or aftermarket) or any similar wishbone designed to suit your available space, so alleviate the silliness of the R32 design. Then you can locate your inner pivots to provide the correct kinematics (camber gain on compression, etc).
    • The frontend wouldn't go low enough because the coilover was max low and the upper control arm would collapse into itself and potentially bottom out in the strut tower. I made a brace and cut off the kingpin and then moved the upright down 1.25" and welded. i still have to finish but this gives an idea. Now I can have a normal 3.25" of shock travel and things aren't binding. I'm also dropping the lower arm and tie rod 1.25".
