Hey Tao, what turbo do you have to suit an LS1? Have a guy wanting to do an LS1 VL. I was thinking ATR46?
-

Made 280rwkw on P98 with intercooler causing restriction (china 510x250x65) on 17PSI.
Waiting for ethanol content sensor and feature pack nistune to arrive and will couple with a PWR intercooler and go back for e-flex. Pretty damn fast lol. Has 3.70 gears so it's not as stupid as same power with 4.11s but has 100% traction and just hauls lol.Specs:
- RB25DET NEO: New nissan head gasket, genuine nissan headbolts- ATR43SS2
- Turbosmart 40mm comp gate off rear housing
- Xspurt 1000CC injectors
- Z32 AFM on factory R31 airbox with lid cut out at rear
- 3" induction pipe
-3" Dump pipe > 4" highflow cat > 3" exhaust with 2 large mufflers
- Nistune ER34 ECU
- 510x250x65 intercooler (china) with 2.5" piping
- Aeromotive 340 fuel pump

Yeah his after external gate version, going to put gate off housing, whats the price for the external gate version?
-
Ive finally got my 25 back in the 31 with the atr43ss2, going to be getting a flex tune done shortly so will update what it does.
Tao what turbo do you have for a SOHC rb30? Mates after something quite large. Does the ATR45 come in a trim suitable for a 3litre?
-
Will have to wait a bit longer to get results of my SS2 on the 25neo, got defected and epa'd lol so rocking the 30e again until later this year.
-
Just dialed more fuel into tune to play it safe (was running 20psi through highflow, 14psi gate on ss2)
Holy f**k hahaha feels SO good, retained all of its down low driveability and once it hits about 3600-3700 rpm its a massive rush of power and noise, even running quite rich still pulls better everywhere than the highflow. Doesnt have the kick from 3000-3400 but after that its like an on/off switch.
WIll post up results once i get access to a dyno.Its hitting 14psi so far on gate pressure no controller at 3700rpm on a logging run.

Installed, housing mod by scotty, rest of welding im finishing up now myself. screamer is done, just gotta lengthen cooler piping to joiner and weld on a nipple for wastegate reference and we're good to go. can't wait to see how the SS2 goes.
-
Aiming for 290-300rwkw on 98 with the ATR43SS2 op6 version, which tao has explained has a larger rear wheel to suit the .63 rear housing. Yeah i don't think it will be an issue and its piped very direct, not a return flow or anything, just all these stories in this thread are making me worried about it haha. i hope it doesnt drop alot of pressure across core.

Hoping mine doesn't get same issues with the .63 rear, however should be easier to hold 20psi externally gated yeah?
My cooler is 510x250x70 , tube and fin, which is worrying me a bit, however can't go any wider due to auto spoiler motors for the flip down lip on the 31. Could go to a 510x300x100 probably max. -
The op6 rear uses a larger rear wheel though according to Tao, says results are very similar.
-
Pulling the highflow off right now after i saw that lol , i love how consistant yours sits at 20psi with the same gate as me, hopefully i don't have issues with the op6 rear housing for control.
-
this makes me think you spent waaaay too much on a 31. Either way it's going to be a monster
more than you can imagine for a 31. lol.
had the car for 5 years though, and was my first car so doesn't really bother me.
*i do everything myself so dont think about fab or labour costs*

Picked up this bad boy today after reading all 530 pages of this thread
Going onto an RB25det NEO in my R31 Ti
- Sard 650cc injectors (pretty rubbish)
- 2.5" cooler piping from turbo to t/b, 510x250x65 intercooler tube and fin (may be a restriction)
- 3" dump pipe, highflow 4" bodied metal cat, 3" exhaust with 2 straight through mufflers
- Aeromotive 340 stealth pump
- Nistune ER34 board
- Hypergear ATR43SS2 with op6 rear end to suit
- IWG welded up
- Turbosmart 40mm comp gate welded onto housing
- Screamer slash cut at passanger foot well
- 3" metal intake
- Z32 AFM
- Stock R31 airbox with highflow 'drift' filter and rear of lid chopped out (loses ALOT of power with unmodified lid, tbh most likely going to fabricate a custom airbox with panel filter.)
Hoping for 300 on P98 but will be more than satisfied with 280ish. Going to trial nistunes feature pack flex fuel most likely as well and bang some ID1000s or similar in for when i want more power. However on a R31 live rear axle with a poo rebuilt LSD that works when it feels like. will be a bit death lol.

Hey Tao, What would you recomend for a VH45DE engine? pref in single config. Street driven so reasonable response around 400rwkw minimum range?
