Why Use Cosworth Over Renault (the New Gtr)


Recommended Posts

From what I have read, Nissan are using Cosworth in the development of the new GTR. Although this sounds like a good move, why would they not call on the resources at Renault.

I would think Renault through their racing heritage whether formula 1 or other would be in an equal position to advise and provide this advice at a discounted price.

maybe it's more relative to the forced induction knowledge/experience that cosworth has, over renault?

more experience with 6's maybe?? maybe there were already connections with the ppl working on the engine, with those at cosworth, maybe even some JGTC connections?

i guess when it comes to specialists engine tuning, Cosworth might have more know-how - same sort of logic with going to Lotus for suspension tuning... both are up there in their respective fields...

then again, i'm probably the worst person to comment on this... maybe Justin can help out :P

Nissan and Cosworth have had an on-off relationship going right back to the late-80's. One well known engine developed by Cosworth on behalf of Nissan was the RNN14 Nissan Pulsar GTi-R SR20DET. As for not using Renault's assistance, I guess it's a matter of 'going with what you know' and have Cosworth on board, rather than risk building what would be - in essence - the first French engineered GT-R. :P

Which would be bad.....

From what ive read its more about Cosworth getting the new GTR to pass EPA regulations which wont be easy for the USA,Renault have lots of Turbo experience from the Turbo era in F1 they also won the most races in the turbo era...

i'd tend to believe in this day and age a matter of financial figures, who can offer what and for how much, and then the contract is awarded to that group. Even though Renault and Nissan share finances, their departments may still operate as totally seperate entities.

It's not exactly like Cosworth are lacking in credentials. They have done turbo all-wheel-drive road cars very successfully in the past (I'm thinking Ford Escort Cosworth when I say that).

Since it was formed in 1958 by Mike Costin and Keith Duckworth, Cosworth has become the most successful engine manufacturer in the history of Formula One, with a string of driver and manufacturer titles to its credit. In addition, it has also achieved enormous success in a variety of formulae, including IRL, Champ Car, WRC, sportscars and MotoGP.

Cosworth began life in a small workshop in London in 1958. However, things quickly grew and a move to larger premises was soon required. The company moved to north London, where it began working on the development of the Ford 105E engine. Cosworth actually achieved its first victory when Jim Clark took a win in the Formula Junior category in his Lotus 18 at Goodwood in 1960.

By the mid 1960s, the company had moved to Northampton where bigger prospects were around the corner. In 1966, Duckworth signed a contract with Ford to develop a new three-litre Formula One engine, and the legendary DFV was born. It got its first taste of victory in 1967, when Jim Clark again provided the maiden victory at the Dutch Grand Prix. The DFV, in subsequent development guises, went on to dominate the sport for 15 years and clinched 155 race wins during that time.

A host of famous names benefited from Costin and Duckworth’s approach – Jackie Stewart, Emerson Fittipaldi, James Hunt and Nelson Piquet all took championships using Cosworth engines during the 1970s.

During the 1970s Cosworth engines crossed the Atlantic to take the Indy/CART world by storm. There, the DFX version of the F1 powerplant began to take an incredible 151 race wins in a 14-year reign, culminating in ten driver’s championships and ten Indianapolis 500 victories.

As the 1980s became the 90s, Cosworth continued to provide winning power, with the Ford Sierra Cosworth RS500 taking the 1987 Touring Car world title and the Cosworth-powered Ford Mondeo winning the World titles for Paul Radisich in 1993 and 1994.

In Formula One, the DFV was replaced by the HB which won 11 races between 1989 and 1993, while Nigel Mansell’s 1993 CART championship and Jacques Villeneuve’s 1995 Indy 500 win were both provided by Cosworth power. In 1994, the Zetec V8 F1 engine was introduced and powered Michael Schumacher’s first world driver’s title. In rallying, the Ford Escort Cosworth notched up numerous wins during the 1990s and the Duratec-R engine in the Focus WRC gave Ford more success.

Bringing the story up to date, in 2004, Cosworth provided the power to 30% of the Formula One grid, as well as to the entire Champ Car World Series and the Ford BP Rallyesport Focus World Rally cars.

The only good engine I can think of made by Renault is their F1 engine, which has little bearing on how to build a decent road car engine. If you look at their street cars, most of the engines are average.

Cosworth has much more experience when it comes to building streetable engines. You've got all those hot Fords (Escort, Sierra, etc) and they tend to do a lot of work for specialty low-volume British marques too, I believe.

I have seen a doc. concerning the Cosworth Empire.

Its beggining and future prospects.

The new Infinity gtr35 ...oh not skyline boys...but INFINITY, is a car designed for the USA so more

than likely will come with soft suspention :woot: a large and heavily weighted machine to

compete with the HUMMERS . :D

As far as Cosworth is concerned.......they have no strengths, all i saw was weakneses.

The flop is about to launch.... :laugh:

^^^ I also heard Nissan are designing a special 'sub- $30,000 GT-R' based on the R31 sedan just for you Tekin, complete with neons, 22inch DaVincenzo wheels, Luis Vuitton pattern crushed velvet interior and triple supercharged steam engine with 88mph speed limiter... should be good for 2006 --> 1885 times...

You are just waiting for me to reply..... :laugh:

Go on have your laugh....I am getting a scooter for my next ride...

This petrols is killing me.

Oh by the way ...you have to have owned a GTR before you can comment on one... :kiss::laugh:

OK lets see what you have said on the other thread..

Rezz you should not be so unkind to Tekin, he comes from MELBOURNE, he probably has a VALIANT CHARGER at home painted that bloody awful green, with chromies.

I remember hearing something a while back in relation to a patent Cosworth has on a Zircon Sand based casting process - they were going to use it in manufacuring the new GT-R powerplant - could have had some bearing on it.

I think the moulds are made with ZS which ultimately results in the ability to achieve much tighter tolerances...

    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
    • It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.
    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
