    I have a friend on here who had a 2.8 with an efr 8374 with a 1.0 rear on it, the emap was rising fairly a lot and the turbo speed had been reached, with that setup it made 485kw the wheels. He then swapped the rear out for a 1.45, the emap went down, the power went to near 520kw and had zero noticeable extra lag

    In the process of building a nitto 3.2 mated to a PPG sequential. I went back/forth with my EFR turbo choice. I think I will go with the 9180 (twin scroll manifold w/ twin external gates). I feel like going with a 1.45 a/r since I'll be using a sequential.

    Any newer takes with this turbo on with a 3.2 stroker?

     

    Why 9180?

    Why not 8474?

    No real data as such but the 2 G series cars id piped up have both already ditched them lol.

    2.2L evo with a G35 900 .83 rear made 500kw but was quite lazy. Evo has gone to a 9280 1.45. Results are yet to come. 

    3L GTR with a G35 1050 1.21 rear made 630kw The GTR went to a 6875 PTE and the PTE Chopped it absolutely everywhere and made quite a bit more grunt! 

    I have a dynosheet somewhere but CBF finding it 🤣

    Back onto the topic of billet turbos instead of billet blocks

    i was at a dyno day at jem early this month and decided to ask Adam about the 6870 2.8 combo while I was there, he said it should make 650kw at the wheels and be all in at 4500

    I think he's dreaming....

    Have a look another look at Reapers graph that you posted? 

    A large static cam 2.8 will do better than a 3.2L V cam? 🤔

    I don’t have my heart set on the 6870 at all, in fact I’m still pretty set on the 6466 with the slightly bigger rear on it, doesn’t mean we can’t try and see what else is out there and get some discussion going. 
     

    The thing with the vcam is if I decided to go back to it, It is cheaper to sell the step 1 and buy the step 2 or pro then it is to buy the parts to upgrade it anyway 

    The thing with the step 2 and or pro is you really don't need the extra 20° of swing they give you and realistically the cams are still average for your application. 10.8mm of lift maximum is more than ample anything over that is just hammering your top end unnecessarily.

    30° of swing is more than enough and a custom grind cam will far outweigh the extra swing performance wise & $$$ wise! 

    A custom grind intake cam will be thousands of dollars less so I don't know what you're basing that on? 

    I think you're bang on in going up a turbine size mate for the extra flow and to help keep the EMAP happy with the extra cubes.

     But f**k those Jun cams off dude lol! Or at least the intake cam 🤣

    I’m building a street car that I can take roll racing, not a car dedicated to winning roll racing. there’s a difference! 

    Realistically a 2.8L with a 1000+hp turbo isn't gunna be THAT streetable. It kinda puts you in "the middle" as it's not going to be good on the street & it's not gunna get you anywhere in roll racing either.

    Obviously this is just my opinion and no doubt a 650kw car is gunna pull like a freight train once it wakes up!

     But making a car that's gunna be laggy on the street to compete in the 2nd biggest dick shwinging contest after WTAC every couple of weeks/once a month is going to ruin the car for all those other drives you will take it on.

    I think you're off ya head ditching V cam and the 6466 man. 

    6466 + vcam + 2.8L + sequential will make for a brutally fast/responsive car thats gunna do street duties, SAU cruises amazingly well! But realistically it ain't gunna change your roll racing result at the end of the night cos you're going home once the big boys come out to play anyways. 

     All you're doing is sacrificing a f**ktonne of low/midrange & overall average grunt for a lazy 50kw up top dude? At the expense of 80-100kw of midrange grunt  and far more drivability off boost ditching V cam.

    Ditching V cam on a street car is a huge mistake. You've felt the gains its given you and you're basically going 2.8L to give you the low down grunt V cam has given you. You're taking a big sideways step with shit cams and no skinny cam. Bigger cubes & v cam is the only logical choice for a street car. All you're building is a top end screamer in the "guise" of a street car imo.

    The DBW does nothing but mask the problem, it is still totally pointless restricting the engine when you actually need the power, the DBW cant magically 'add' power. And this is why its important to use the right turbo, way too many people get hung up on the modern bullshit as a panacea for bad fundamental choices, a loss is a loss, too small a turbo gives power where its useless and not enough where its needed, simple.

    Thats a pretty "broad statement " turbo size pends on many things. Too big of a turbo is exactly the same as too small of a turbo it depends where you drive the car as to where you need the grunt.

    8474 didn't deliver anything special in my application, 2.8L high comp RB26 2.8l.  WIth a 1.05 rear, compared to the 9180 it behaved very similar.  It was quite more eager to come onto power faster on full throttle in 1st and 2nd gear, but it felt so restricted as soon as you got it moving.  The 9180 didn't feel like it was choking the engine as much, overall felt much more healthy and a better match  

    The 9274 was the next turbo I was going to try, but it looked like it would just be an extension of the drawbacks I had with the 8474.  74mm wheel simply too restrictive to swallow all the flow the larger compressor can give.  Wasn't impressed with the 9280 from very limited testing I done

    Why are you chucking money at all these different turbos when your setup isn't optimised?

    $1570.

    But I also found a nistune for $650 but some guy said the nistune will restrict my power to around 300kw. 
     

     

    $1570 is a rort. I wouldn't pay that for that heap of shit.

    Whoever "some guy" is is a knob lol. I'd go Nistune over Halal all day.

    If you want the best its Motec or Emtron really.

    I agree with the Pig. Build it the right size with quality muffs and there shouldn't be an issue. 

    Something the pig didn't point out is the mess this shit leaves under your car. These things are starting to become quite valuable too so having it caked with exhaust soot and oily shit makes it a nightmare anytime you wanna work underneath the thing too.

    This kinda thing devalues your car and is what draws the police's attention to our cars with this kinda rubbish and unnecessary noise.
