"Street" GTR nearly ready - at last

[Munro]

After 7 months of being off the road after the harmonic balancer broke the snout off the crank, my "street" GTR (Dougs old R33 GTR) is nearly back on the road.I only got to drive this car a couple of times before I broke it, so it's great to see it almost ready after such a long time.

Despite what 'some' people think, I am on a buget like everyone else, so this project took much longer than expected.Parts & machining also held things up, but Mick, Mark & Tyson at Tilbrooks have done an awesome job to bring on this new build & turn this car into a very different animal then before.

When I bought the car from Doug it had twin TD06 turbos, which endowed the car with amazing top end power, but with no boost before 5500rpm & a synchro gearbox, it did not really suit my application of hills driving.

With the engine pulled down, we thought about what we really wanted - & thats

mid range torque, a generous power band, & a gearbox that would compliment the new engine setup without blowing itself to bits.

As the block was already bored & the pistons were showing signs of wear, we decided to start with a new block & crank.O ringed, linehoned, & bored to suit the new wiseco forged pistons, the block was blueprinted, the carillo rods were cracktested & resized, & the crank was knife-edged, nitrided & the whole lot balanced together with the OS triple plate clutchm & new R34 balancer to spin to 10,000rpm.The engine will not be reved that hard, but at least we know it's been done properly.

The race car has had a dry sump fabricated for it, so the modified Trust sump from the race engine seemed a natural addition for this engine, along with the HKS step pro cams & valvetrain ( the OS 3 Litre now has HUGE Tomei cams), the 1000cc injectors( race car stepping up to 12 x 1600cc), and the ARC coolant header tanks system( no point on race engine as radiator going in boot) all perfect hand-me-downs from the 'other' R33.

With additional head porting, extra compression(9.6:1),full metal gasket kit & meticulous preparation by Tyson & Mick, the engine was assembled together with the existing HKS cam gears, GReddy plenum, 85mm single throttle body, Trust pulleys etc etc.

[hippy]

it did not really suit my application of hills driving.

is that all you going to be doing??

[Munro]

The Trust twin entry intercooler is being replaced by a new custom single entry bar&plate cooler to suit the 800hp garrett roller bearing turbo.Mick has fabricated a killer manifold to mount it & the huge Sub-zero wastegate.

Should make low 400s at the treads on PULP, but with awesome mid range torque.When I'm ready, we will tune it with better fuel for high 400s & then drag race it(just to see what it does as this car has never been raced), but what I am really looking forward to is the raised eyebrows from the two-wheelers up the gorge.

I would never contemplate this setup in a RWD skyline, although it does have an HKS torque split controller for those times when massive sideways action is needed!!! Hence the number plates.

After selling the R34 earlier this year, I am hanging out to get this car on the road. Looks like I'm getting a good Christmas present this year - & it's wrapped in silver.

See ya on the street.

[Munro]

For those of you saying - yada yada yada, where is the bloody race car?????

It is happening - slowly, but surely. The streeter has taken priority ( & why not - how do you guys feel when u cant drive your cars?), but now that is nearly out of the way we can concentrate on the crazy one. And it has gone crazy.

The "3 litre Streeter" is no more. It is now a full blown race car.

Methanol, 12x1600cc injectors, grout filled block & the hugest turbo you have ever seen are all sitting on the bench waiting to go on. The head can only be described as "off it's face" with custom ferrera valves, 11.6mm cams, +++.

The dry sump is a work of art, & the whole engine should be together by next week.The Holinger is waiting for some new parts(just to be on the safe side), & after the holidays Tilbrooks will be going hammer & tongs to get everything ready

for the 4,6& rotor Nationals.

We won't get time to paint the car, but it will still look OK - so stay tuned.

[Steve]

Good to hear santa will be kind:) That must make Mick, Mark and Tyson elves:p

Huge turbo going on the drag car???? I thought the one going on your street car was bloody huge! (saw you and it at tilbrooks the other day - I was wearing white)

Where do you expect the street turbo to start making boost?

[Munro]

Nah, thats a medium one - the race turbo will support 1300hp (tho we wont be making that much)The 3 litre will probably start boosting around 6500 (will rev it past 10000) but the streeter should come on around 4-4500.

This is still laggy but with an engine built to sustain 9500 rpm will still give a good power band coupled with the close ratio 5 speed dog box.Pfitzner's box is quite streetable compared to the old Trust box & the Holingers, & because it wont need the clutch on changes should keep the RB26 on song & right in the meat of the torque range. Of course it wont be the friendliest car in peak hour traffic, but when there is a gap - look out commuters.

While I'm on the single turbo subject, I have a new tow ute in the garage. I have changed over the SS V8 ute to a new XR6 Turbo ute.I've only started running it in, but am very happy with it so far - looks great in Blueprint with GT wheels & brakes.

[hippy]

u go through cars like i go through undies ... in fact i dont' think i go through undies that fast!!!

[hippy]

oh.. please compare the SS to the XR6T please ... which is better ??

[Munro]

u go through cars like i go through undies ... in fact i dont' think i go through undies that fast!!!  

Well, I have sold 5 cars this year ( equals my record for sales in one year )

turbo diesel rodeo

Honda S2000

EVO VII miss this one

R34 GTR Vspec what was I thinking

V8 SS Ute no more V8 in shed

But times they are achanging & sometimes u have to move on - or u have no choice 'cause u need the shed space. Ba Bow. :aroused:

[Munro]

The XR6T is 150 odd kilos heavier, has leaf springs rather than the holden's independent, & does not handle as well (but the SS had bilsteins). This one is auto 'cause the ford 5 speed is cr#p & can only tow 1200kg.Power delivery is good, & overall the ute feels very good to drive - love the dash/interior except the poxy cheap door interior door handles.

The modded SS had 235rwkw & 6 speed, so ATM would be quicker than the ford, but not for long - I have already ordered a power upgrade kit for it which should put it in the vicinity of 270-280rwkw & buckets of all important torque.I think the SS would be shamed with this new setup, but I will always like Holdens.(Unashamed V8 head at heart - even if they are fast becoming boat anchors - haha.)

At least the race car will never be late to the Drags.

[hippy]

top stuff ... but will that power upgrade kit void your warranty??

[Munro]

Warranty? Dont be weak. Never stopped me before.

Short engines are $1800 approx. If it breaks then it wasn't good enough & needs to be made better anyway.

Dont know anyone with a GEN III V8 that hasn't done edit & extractors. The cars can easily be returned to std if there was a problem. The ford should be the same.

Some will be happy with std power, but if u want more u have to take the plunge.

Some new ford turbo owners might wait 3 years till the warranty runs out before modifying - but I am not interested in that - to each his own.

As a short guide...

My XR6T ran 12.9 with 300rwkw

My VYII ran 12.8 with 210rwkw

Good luck with the Ford Powerup John!

[TIMMMAYYY]

out of interest martin which oone ran the better 60foot and by how much?

[Martin Donnon]

out of interest martin which oone ran the better 60foot and by how much?

Ford XR6T 60' 1.92 sec

VYII V8 60' 1.77 sec

[whatsisname]

Nice 60's Martin, if they were on street rubber?

[Steve]

5 cars, almost time to apply for a dealers liscence:). Good luck with the GTR, it looked very, very tidy when I saw it, perhaps another entrant for the SAU SA autosalon stand?

Any ideas on whos powerup you will be using for the XR6 yet? I have heard 'rumours' of 11 sec cars getting around on the east coast with a few bolt ons.

Martin, with an extra 90rwkw, why does the XR6 run slower? Must be alot more to it than a 150kg and 0.14 60 foot times, with the disparity in ETs, it would appear something else isnt right. Also, as the holden has IRS it would be an advantage to the ford?

[Rob]

Howdy John, long time no talk! .

Far out that street GTR is sounding extreme!, I am very jealous!.

Also the Drag car is sounding very crazy also.

I think I say this for everyone, we all envy you very much

I think with everyone getting there cars back on the road this calls for another "Drifty Cruise" !, I am thinking either a Saturday day cruise or a Friday night special and maybe something mid Janurary after everyone has got over xmas & the xmas holidays.

Now I can not promise it will not rain, but looking at this weather we shouldn't have a prob! .

What do we all think?.. will be good to get all the old school together with the new school.

Rob.

Nizpro have one in the 10s, and APS have one doing low 11s.

Can't wait to see these cars of Munros in action.

Dont get too excited lads, only 'Commonwhores' and 'Fowlcans'
