Hi Guys,

I currently have a GT2835 Pro S putting out 273 RWKW with the usual mods (PFC, injectors, fuel pump, exhaust, front mount etc etc) running 18 PSI.

I am getting pon cams soon 256 inlet 260 exhaust to the the power up a little more (to about 290 rwkw)

Anyway, my question being, is it worth my getting a 3037 0.68 housing to get around the 320 rwkw mark (hopefully), or should I just wind up the boost a little more after I get the cams on the 2835 to push out 20psi and get around 295rwkw?

that is, is it worth all the hassle/money for an extra 25 rwkw and more lag?

Would my 1/4 mile time drop by getting the 3037?

Cheers guys

I dont think you'll make a real 295rwkw out of a 2835. Happy to see that proved wrong however :)

The 3037 wont make 'that' much more, the rear housing is the governing factor there more over the comp wheel which will flow more no problem if you put the bigger housing on.

How it affects your 1/4... proably not a lot. You'll still have a pretty reasonable power band to choose from if you upgrade, it just wont be as big as the 2835, but considering drags is more top and low, you should be fine there.

Your 1/4 will more be dictated by the tyres/grip you have for the most part with that kinda power. If your doing it on street rubber... you wont notice much as it'll all be wheelspin with either power.

Cost vs gain... end of the day you'll benefit more from decent rubber on the car as opposed to upgrading the turbo with 1/4 time in mind :D

If you want to pick up a hardly used 3037 pro s turbo kit click on the link to my for sale thread in my signature for more details :P

Make me an offer if your keen.

Cheers

Dollars and major hastle... I wouldn't bother...

What ash said about rubber is a great point... But its a recurring investment... A turbo is a one off spend...

what do you intend on using the car for? I have the same turbo as you and a well sorted suspension setup and i can't really see the need for any more power on street tyres... hence me looking for a gtr atm... :spank:

how's your suspension setup? If its not full house thats where i'd be throwing any lazy cash... But thats me :wave:

+1

i wouldnt bother spending more money for such little gains, not woth HP vs $$$

all depends on what you intend on using your car for, 273rwkw is plenty of fun for the street :spank:

:wave:

I want to make it pretty much a straight line car. For this reason, I got the stock springs in the back, and a good bilstein shock setup all round.

I guess I'll see what I want to do after the cams go in. I would hate to get the 3037 and be disappointed as it wont have that much more power gain, with more lag.

Maybe it's time to upgrade to GTR? haha.

Thanks for the advice people.

dont we SA people need a race track before worrying about straight line performance?

sell it and get a garett 3582r-iw .82

boost will start low 2k

full boost before 4k, and potential for 350 rwkws.

i would think a 3582 at 15 - 18 psi would be smoother on the engine then a 3037 on 22 - 24 psi

thats why i allways stir up the gtrs lovers

after 6 months they upgrade,

following 6 months they upgrade again...

costs a fortune to upgrade dumps and lines every 6 months.

waste of time

stick a gt3582r-iw on it from the get go and just dont crank the boost as high.

when you rebuild and want more power turn the wik up. simple cost effective modding.

GT35? That thing wouldn't even start to spool up until 3,500 rpm with a 2.5 litre engine? I don't want to have to be reving my car past 5K everywhere I go just to get it moving.

Anyway, I'll see how it goes after the cams get put in (30 Oct).

What is a slightly bigger turbo than the 3037 that HKS make as a bolt on application?

There is none, the 3037 is the biggest bolt on kit hks make for the rb25!

Ive recently been in a jzx100 with a 3037 pros and a 34 gtt with a 2835 pro s

the 34 was much nicer to driver round town than the 100

and the 3037 was fairly lazy and thats on a vvti late model 1j

it did get abit hairy compared to the 34 which just seemed to keep pulling

they ended up making similar power to on the same dyno

low 250's on a mainline both standard internals at sensible boost levels i.e 1.2 ish

(3037 was the bigger .86 rear housing)

Edited by 1400r

the 3037 is not lazy in my engine it comes on hard and early all the way to 8,000 rpm

if you get the right money for the old set up do it.

or get your self a nos kit

    • Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
    • What ECU are you running? This is probably the biggest question. If it's a PowerFC, I'd probably change the ECU and get something newer that will handle the injectors in a nicer way.
