Volga is fantastic, I bet that hit the ground hard, they weigh as much as a small country don’t they?
[/quote]They are indeed heavy… but they’re also built like tanks from what I hear. They still had front kingpins until 2002.
No, not really. RB28DETT is a GT500 block based in design on RBX block, which in turn is based in design on RB26 block.The RBXis as much a “modified rb26 block” as you are a “modified your father”. All the lubricating and cooling was re-worked for the RBX, and to finish it of, the RBX is not compatible with both RB26 and RB28 heads. It wasn’t “modified” it was separately cast.
Of course they’re incompatible. All RBs were cast with significant differences, and few of their heads are compatible with each other. They’re all still RBs stemming from the same design though; that were enlarged, refined, and for speciality purposes like the N1, RB-X, and GT500, strengthened for the demands of racing.
Sigh
The RBX and RRR, as well as N1 engine are all incompatible with anything but their own heads.
There’s one main difference in “regular” RB series engines, it’s either VVT or not. You can not bolt a vvt head on a non vvt block and make it run, and you can bolt a non vvt head onto pretty much anything. There are no individual casts for each version of RB engine with “significant differences”, more so the 2.0 and 2.6 engine blocks are cast same, and machined differently. 2.5 is cast differently to allow for changes to the front of the engine block.
According to what I know; the 78mm and 86mm RBs have completely separate castings because of the large bore difference. Then there are the race castings for N1, RB-X, and GT500… then the VVT differences, as you mentioned. They’re all different. As for heads; I honestly don’t know of any ones that are cross-compatible without serious modification (or possible at all) besides the RB30E and RB25DE pieces.
Just to clarify, I’m not stopping this because the last post you’ve made has no wrong info in it, I’m doing it precisely because each post you’ve done has it.
What is this sorcery?
Seriously though, of all the cars the Welsh could possibly make, they have a company producing lightweight, mid-engine rally coupes. I love it.
… ok ok not particularly convincing I know. I can’t really find any proper offroad lambos. Only unintentional ones. And this one is road rally, but it’s also road rally ON FIRE
…ok Lambo’s not a great prospect. While looking for more “exotics that have no business being rally cars”:
Which kind of reminds me of:
911s actually DO have quite the history of being used in rally.
Not at computer, but ford australia did produce a xy falcon 4x4 factory option anyone care to google and post a pic. And aussie amatuer rally 180b/gemini/cortina must have a dirty great 2bbl carb and a 14" air filter sticking out the bonnet. Old school 4cyl power…is that lundgren from the expendables?
Thats her, they also did a gtho version and in person they are god awful…interesting but awful awful cars…and looks like i may be joining the porsche club the xr8 has 3 people interested aus wide and the offers are much more than i paid for the car and the French roads are calling @winning
The Lancia ECV1 (Experimental Composite Veichle) it’s the evolution of the S4, unfortunatly he never run a rally due to the soppression of Group B and S. only one were made. i had the opportunity to talk with the owner Beppe Volta (an Ex Lancia Tuner), he said that the engine made 600hp on low boost, more than 800hp on high boost map!
There the engine, 1759cc 4 cylinder “Triflux” crossed valves layout (intake-exhaust exhaust-intake) with two exhaust downpipe, 2x KKK K-26 Turbines, and one intake collector.
