Garage 7 just finished tuning mine today. Boost is straight off the wastegate spring 17psi and boost controller not dialed in yet as my rear brakes locked on witch put a holt to the tune.

Engine:

S2 RB25DET Unopened apart from cams.

GTSR exhaust manifold

Kando TD06 20G 10cm with 45mm turbosmart hypergate

3inch turbo back exhaust-Kakimoto cat back

Splitfire coilpacks

Tomei pon cams 256 8.5mm lift

Adjustable Tomei exhaust cam gear

N1 oil and water pump

1000cc injectors with top feed fuel rail-Tomei fpr

Freddy intake

600x100x76 intercooler with custom/short piping

Denso intank, 044 external and 2l surge tank

52mm radiator with 2x12inch craig davies thermos

HKS 13 row oil cooler with grex oil filter relocate block

That's all I can think of at the moment. Will be rebooking after the new year for 20+ pound run.

E85 ?

[Ad's]

Yes sorry E85. Will push over the 300kw mark once the boost it turned up. 350kw may be possable apparently as she has heaps left in it.

Here are two more ATR43SS2 graph sent in, all E85 fuel, R33 Unopened engines. 3inches intake and exhaust, ECU, generic 600x300x75mm cooler, and E85 fuel, Peek power made at 19psi.

This is Traditional ATR43SS2:

Twicked version, conservative tune, but notice the difference in upper rev torque:

Gday all

1993 r33 gtst rb25det

Tomei poncams 256s 8.5mm lift

supertech valve springs w/ matching retainers

forged short block with cp pistons and tomei rods. Acl race bearings. Arp bolts all round.

Forward facing plenum

90mm throttle body

Fmic

Discotune steampipe manifold

Gtx3076r .82

3 inch straight through exhaust

1400cc injectors

walbro e85 lift pump, surge tank with 044

Haltech platinum pro plugin

Yellow jacket coilpacks

heaps of other good fruit too.

This is just the base tune which made 295rwkw at 17.4psi, caltex 98.

Coilpacks were holding it back on running more boost as they are on their way out, so i am converting to ls1 coils before tuning to e85. Full fuel flex system in the car ready to go.

Will update when the e85 tune happens.

Hahaha the classic uncle eddy's special

That's one strong engine though!

Now this has given me a bit of hope for mine

Very nice results too

R34 GTT RB25DET NEO unopened engine.

- Adaptronic​ ECU
- 1000CC ID injectors
- Factory cams, cams gears, and all manifolds.
- HyperGear ATR45SAT Ceramic Ball bearing Internal gated RB25 bolton Turbocharger
- JJR 3 inches turbo back exhaust, front pipe dropped before cat.
- Walbro 470L/H Fuel pump
- 4 inches induction pipe
- Split fire coil packs
- PWR 600x300x81mm intercooler

Some updates on the ATR45SAT CBB Turbocharger. made 336rwkws @ 22psi on Pump 98 fuel, internally gated bolton.

Sorry not the prettiest looking. I just can't get same power out of fancy looking bits.

I think this turbo is too big for a 3 inches turbo back system for an R34 GTT. I can't get much more power then the G3 SAT with exhaust connected. Result above was obtained from front pipe dropped before the cat. it would be a very nice turbo to run on an external gate off an factory exhaust.
