Advice needed thanks.

[trustr32]

Id stick with the individual throttle bodies personally. it gives the intake the unique gtr ufo type of sound. but upto you really they both look pretty nice.

[Tyranus]

What i want to know is if there is a big power difference inbetween the two plenums ?

From what I can understand is that for big power RB26 applications single throttle plenums are the way to go when you're running a single turbocharger setup, whilst six throttle plenums are more useful for retaining low mount / oem turbo chargers.

Hope that helps.

I guess its the same go when you have an RB28?

Cheers Mate.

The N1 block is here, still waiting for stroker to arrive.

Its being sent off to the machining shop tomorrow, its slowly coming together

first ive heard of that...

people are making 900hp plus with the standard plenum and throttles! the thing with the 6 throttles is that it causes a slight disruption with air flow (turblulence) and can be hard to tune, however there are plenty of people that can tune them and do time and time again

Look mate, I acknowledge that standard RB26 plenum can be used in high horsepower RB26's. HOWEVER, Standard throttle bodies on big powered RB26 can cause difficulty when tuning the car (as you have mentioned) and research has found that single throttle setup ups for big power applications (500+kw) are better for flow and tuning.

Just have a look at all the big powered RB26's (500+kw) and you will see they do not use standard six TB's.

Also, I do not see many low mount set-ups running single throttle plenums, why?... because there is F all performance gained from that upgrade at that power level.

no need to get up on your high horse about it! clearly you are a little sensitive on the issue but im not going to get in an E fight with you when clearly you cant except either

[Ants]

Nope, not sensitive on that issue.

I don't have a high horse either....Just stating a fact buddy.

Now lets just move on and give this build thread back Sedat.

[Tyranus]

There has been a massive delay with my build. The workshop who is doing my build is moving from Campbellfield to Sunshine, once they are settled in my build is going to commence. In the mean while i have picked up a Nitto oil pump.

Parts that i have so far:

HKS Cam Gears

HKS Fuel Rail

HKS T51R SPL with T62R front wheel

HKS Manfiold

HKS 60mm Wastegate

Nitto 2.8 Stroker

Nitto Oil Pump

N1 Block

Mildy ported RB26 heads with bronze valve guides ready to be sent off for a massive overhaul + CnC porting.

After a MASSIVE delay it has finally arrived.. my Nitto 2.8 stroker..

Because i had to wait so long for my stroker to come i took my mechanics daily for a little "test" drive. Least to say i was very impressed with the cars stock performance.

[linkems]

Almost looks too good to take out of the box

For a whizzer as big as you are planning to run, go the 90mm single throttle body plenum. It will be easier to tune. Any advantage of ITB's will be negated by such a large turbo and the delivery it will provide.

I don't buy into the 'single TB for big power, ITB's for small power' internet theory. It's been disproved in the real world time and time again. Single TB's are simpler to tune with.... and big power with an rb26 means big lag. The main advantages of ITB's are in the lower end or transient throttle- both of these areas are 'dulled' down with a large turbo.

Personally I chose to stick with ITB's, greddy plenum and twin trust td06 l2's on my rb28. I believe I achieve better throttle response, better transient response, higher intake air speed, more even air volume between cylinders and a better sound.

+1 on the better sound!

Small update:

Nitto oil pump is arriving this week.

Ordered these parts which should also be coming this week:

Tomei Oil Restrictor

ACL Race Bearings (Main & Conrods)

ARP Main Studs

ARP Head Studs

Nitto Full Gasket Kit

Nitto 1.5mm Head Gasket

Nitto Oil Head Drain

ATI 1000HP Balancer and Water Pulley

Thats it so far..

[r32-25t]

What the nitto head oil drain worth?

[Tyranus]

What the nitto head oil drain worth?

Because my mechanic is good mates with Nitto, he got it alot cheaper than its RRP...

[Tyranus]

Went past to the machine shop, i was greated by pleasent surprise.

BJ Engine Worx have already started working on my block
