Hey all

Ive decided to go the neo 25/30 route, retaining the VCT for my r33 track car

my goal is above 500kws at the wheels

Parts im looking at are

- ARP Main Studs

- Forged rods ideas?

- Pistons ideas ?

- Sump Ideas?

- Going to have the block drilled for 12mm GTR STuds

- Cams ideas? 

- Turbo maybe a garrett 35/84?

- swap or sell my plazmaman and get a neo one with stock runners

Im going to get my tuner to do some oil upgrades also

 

id then sell off my current injectors, fuel rail (unless it would fit the neo head? from a rb25), spitfire coils, 6 boost mani and FP HTA 3076R turbo

Id re use the exhaust, turbosmart wastegate, fuel pressure reg, link G4 computer

this sound about right?

any help and ideas would be great

I bought a modified sump from Lewis Race Engines at Callington. He takes a standard sump, adds wings on the sides and baffles around the pickup. He does it on a swap basis - you give him your sump & some money, & he gives a modified sump. This was originally on an RB25, and is now on an RB30 bottom end. I can't remember the price, but I am happy with the product.

It all sounds like serious intent.  So probably going to take a serious spend.

Sump - dry

Rods - Carillo

Pistons - SPS

Cams - Kelford

Ignition - Yaris/Audi/R35/Chev coils, crank trigger

Turbo - BW 8374 or Precision 6266 at a minimum.  Probably go up to a 9180 or 6466.

Head studs I would go to 1/2 inch.

The focus of the build would be airflow, and reliability of fuel, oil, ignition, and cooling systems IMO.

Make sure you source the Yaris coils yourself, as the "kit" ones often come with generic Yaris coils..
Buy the loom/bracket, but better off getting brand new coils from Toyota OR remove them from a wrecked Yaris.

Sump wise, just get an ASR one - great quality and you have options for trap doors/baffles. I had one made up specifically for my AWD NEO motor to fit a RWD R33. They provided a brand new pick up, and welded up the sump too suit.

If you're injectors are 3/4~1/2 height (without the extensions) then you can re-use it on the NEO intake manifold without any fancy injector bosses.

I suggest you get a decent oil pump OR alternatively get billet gears by Spool to suit the pump.

Yaris coils or the ones from the ZZ motors in hot Corollas (& Celicas).  They vary in some small details, like which way the plugs point.  The right ones to get are the ones with the plugs horizontal, not angled up.
Make sure they are Denso.  Genuine Denso.
Hi sorry to hijack but ive never heard of using yaris coil packs. Why so?

They make silly amounts of spark and don't have issues like LS truck coils which at times like to fire early when you add the wrong dwell which can lead to you taking out a motor.

Also who wants LS parts on their motor? Haha

Why the 1/2” head studs? I have read that some don’t like to do that to the RB30 block as they weren’t made for that size, and possible warping of the deck with meat taken out around the threads. So the alternative is ARP RB25 studs, why not do this since the block AND head are made for that size (you are running an RB25 not RB26 head). Just curious, I’m no expert.

Would love to go 3.0 under my neo det head!!!

    • 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.
