yeh f theres another gb im in too.. spewing i didnt get in with that last one!

what are the full benefits of the extractors performance? sound? fuel efficiency?

Car revs out better, less flat spots. Gives more performance in the low and mid-range. Sound is changed as well.

As there is no forced induction, you can't push more air into the engine. Relieving the restrictions in the intake/exhaust system is the key to making power.

Larger mandrel bend extractors and HP Coating helps to scavenge the exhaust gasses out of the engine quicker.

Combined with a hi-flow cat and mandrel bend catback system means that the exhaust gasses leave the engine quickly which in turn means more air can get back into the engine quickly. Air + Fuel + spark = Power. Fast air flowing through an N/A engine means more power is made. Jap engines typically make power through revs, so being able to get through the rev range quickly means that real-world performance is improved.

Fuel efficiency ultimately depends on how a car is driven. eg: I can use half a tank in a week, or in a night. It depends on how much right foot is applied.

Hey Guys,

I may be interested, R33 GTS4 RB25DE. How much would it cost?

i think James is in the process of figuring that one out now. im not sure whether yours will be different, as obviously youl have an extra drive shaft in there somewhere to contend with...

g'day guys... sorry about the delayed response...

i've got a reply back from partsco.

all prices are subject to current exchange rate

we need 10 confirmed orders to get any sort of discount from Coby.

D12 extractors ~AUD$180-190

F124 gasket ~AUD$10-15

HP coating ~AUD$250-260

Shipping (track and trace) to Australia ~AUD$110-120

at this stage, i need 10 PM's with a definite yes to go ahead. once numbers are set i'll require a deposit to lock the buyers in, in previous buys i've not done this - however i've been caught out with people pulling out at the last minute. this deposit is refundable, only on the condition that we do not make the numbers required for the group buy to proceed.

cheers

eug

I am keen for a set for RB20 DE

R32 skyline

D12 extractors ~AUD$180-190

F124 gasket ~AUD$10-15

Shipping (track and trace) to Australia ~AUD$110-120

So im looking around $325 for a set ?

How many numbers do we have confirmed so far ... Im in talks with

Craig Saunders

Director

Partsco.com Ltd

If we can get 10 or more people confirmed as definite we will get a good discount from COBY ...

Craig has informed me that it is more financially viable to go in the group buy than it is to proceed with my 1 off order , so I may get refunded from my current order and proceed with the group buy ...

but it depends on how many confirmed orders we have so far as to weather or not I cancel my current order and proceed with the group buy ...

I currently have payed $306.25AU delivered to my door

If we can get 10 or more confirmed this number will be a lot less ...

well if your in contact with partsco then what am i doing here??

at this stage there isn't enough numbers to go ahead as what i was initially led to believe. truth of the matter is that this has occurred time and time again over the years and quite frankly it ruins it for everyone - as that's how group buys work.

people who have PM'd me so far:

hr32gts

na_beast

ShanO'

Peza

if we do not get another 6 people then it can not possibly go ahead, if Mick does decide to purchase a once off unit then we need another 7. although if numbers do not pull through, he may need to just do that to get his headers.

remember you guys asked me to coordinate this group buy, i don't mind helping out fellow forum members - but those who said they were interested but haven't PM'd me are letting the rest of you down.

    • Oof, I will forevermore have those shredded gears in mind whenever someone talks about showing mechanical sympathy towards their car. Thanks for the photos, fascinating stuff!
    • Curious to see how the SpeedTek stuff holds up
    • The holdups last year were drivetrain related. I had the car out right after getting the bearing issue resolved. Third launch and the car didn't move after releasing the clutch. It had sheared all the engagement teeth off the 1st gear.    Thankfully no other damage was done. I set an aftermarket gear beside an OEM gear and found that the engagement teeth on the OEM gear were much larger and better supported. Looking through my bin of spare transmission gears I found that there are two types of tooth on the OEM first gears - the larger tooth and the smaller tooth. It looks like most aftermarket gearset manufacturers base their design on the smaller tooth. OEM large tooth left - Speedtek, OS Giken, etc or OEM small tooth right Decided to give that larger engagement tooth a try. Pressed the ring off an OEM gear and sent it to a transmission manufacturer here in the States. They did their "faceplating" operation with my synchro ring on the Speedtek gear.   I reassembled it, took it back to the track and promptly destroyed the gear itself.  I'll rebuild this and use it as a spare - thankfully just first gear and the countershaft are damaged beyond repair. Definitely disheartening but my welded on engagement tooth ring held up!  Moved to Speedtek's dog engagement design as the gears appear to be much stronger. So far they have taken much more abuse at the track. Also scored a Stillway lockout from the Netherands for super cheap. It's for some other RB transmission so it took a bit of fabrication to fit but honestly a very easy job. I also had to heavily modify the gates as they were very different.   Then for some reason at the last test and tune a silicon coupler below the throttle blew off and took out the radiator and fan. Thankfully it was in the burnout box and not down track. This car is really beating me up - I still haven't made a pass in it. Ran it through the gears many times on the street but it keeps biting me at the track.  Currently in the process of replacing the radiator and remaking the throttle pipe to remove the coupler and use a cast 90 and a vband. I WILL get this thing down the track...
    • Covers most of the above points really. There's a few exceptions but most just see driving as an irritating but necessary task they must complete if they want to get anywhere on time. Also see it as a good time to show their awesome multi-tasking abilities on their mobile and/or doing their makeup.  
    • I don't believe I posted pictures of the second oil pump pickup I added so here they are. Data shows it gets oil pressure up to the relief pressure much earlier in the RPM. Is that important? Not likely... This was just another attempt to fix the bearing issues.   I also heavily opened up the inlet to the pump since it now had to flow oil from two pickups. I believe the diameter increased about 1/8".
