Rover 220 coupe turbo acceleration 0-220KPH (137MPH)

[glamfusion]

to gear placed in 4th and 5th?

@glamfusion

I believe they where 4th and 5th from diesel rover, now i have put the correct gears in with a slightly shorter 2nd gear.

[glamfusion]

@info4jon I do not speak good English.

I have the gearbox of a 620ti. you who do you recommend?

[info4jon]

@glamfusion

Es una cosa de preferencia personal, yo prefiero las velocidades mas largas de la caja original, ya que las de las 620ti son muy cortas y hay que darle mas revoluciones en la quinta para quedar en la misma velocidad.

Si no lo utilzas en la autovia, supongo que la caja de la 620ti sirve..

Personalmente, yo tengo ahora una segunda un POCO mas corto del original y las demas son originales con todas las rodamientos nuevas y on torsen typo b.

[glamfusion]

@info4jon Tambien tengo la caja de cambios original del Rover 420 sli tienen diferencias estas dos? yo lo uso tambien en la autovia. cuantos psi tienes y que velocidad maxima alcanza el tuyo?

[info4jon]

@glamfusion

no debes de pasar 12psi con los pistones originales porque la temperatura del aire sube demasiado (y no ganas potencia con el turbo original, ya que esta a su maximo) y los pistones queman.

[glamfusion]

@info4jon Tengo pistones forjados!

Cuantos psi tiene el tuyo? y que velocidad maxima alcanza? usas msn?

[info4jon]

@glamfusion

Que codigo lleva la caja original? Deberia estar una pegatina con el codigo, si empieza con k7, es el mismo que lo que tengo ahora (aparte de la segunda que yo cambie)

La velocidad maxima no estoy cierto, llega a 240kph a 5900rpm (cuentakilometros) y pienso que siga mas pero no hay manera de probarlo.

PSI, el coche lleva el contralador original y no tengo indicador de psi, pero voy a conseguir uno. De fabrica deberia estar entre 6 y 11.7psi dependiente de la temperatura del aire.

[glamfusion]

@info4jon actualmente lo tengo con 20psi y la idea es subirlo aun mas pero el controlador de la ecu mems o centralita a los 20 psi esta cortando y realiza una falla para proteccion del motor, por eso estoy por instalar un Megasquirt con un map de 4 bar.

Se que los rodamientos de la caja de cambios no resisitiran pero lo atendere en su momento.

No se el codigo de la pegatina de la caja de cambios. la del 620ti tien diferencial torsen (es la que tengo actulamente instalada)

This gearbox is that car? Relationships are longer than the 200 disel.

[info4jon]

@sergiosasa Hi Sergio, its a K7BSUT so it should be from a late coupe turbo but someone must have changed the ratios for 4th and 5th.

I have now put the correct ratios in for 4th and 5th and a slightly shorter 2nd so that the turbo comes in at lower Kph and gives slightly better acceleration.

The 4th and 5th I think were diesel gears mixed with the coupe turbo 3.73 final drive which made them very long. now its much better and Im a lot happier :)

[tutepika]

soooooo nice! its all standard? i have bought one last month and i didnt test it yet.

[info4jon]

@tutepika Hi, yes its standard except for a Cat back Scorpion, 4th and 5th gear are the wrong ratios for the car at the moment so Im currently having my old gearbox repaired to put it back to how it should be.

Parts are a nightmare im afraid...

@testacorsa150

Engines dont break unless people have been playing with them, the only thing is the slight oil weep form the oil feed between block and head. Its not detrimental.

My gearbox is back together now, new torsen, 7 steel caged bearings except for one, all new.New oil seals and completely stripped down to component level, cleaned shimmed and reassembled.

4th and 5th are now original with a slightly shorter 2nd so the turbo kicks in a little quicker and pulls better. Things to look for:

[testacorsa150]

@info4jon Good to hear yours is back togeher with better parts, and better ratios. I hope you will up another acceleration video. I will be sure to do the same if I get my hands on the one i´m looking at. Keep it rolling, and thanks again for your answer!

[info4jon]

@testacorsa150

Cool, post me if you buy it  :)

Will prob do another vid one day, taking it easy at the moment while I sort some smaller bits that need doing.

hope to hear about your new car soon :)

[info4jon]

@testacorsa150

Look for engines that have had bleed valves fitted to boost pressures used over 11.5 psi. Dont touch them.

Make sure your gearbox is quiet.

Check refrigerant is clean, check for water in rear bootwell or evidence of leaks in the car.

Boost should kick in at 2100rpm, if it doesn't something is wrong...

Check for corroded hoses and stuff under the bonnet and check the oil is relatively clean.

All levels should be between min and max, if they arent, its not been well looked after...

[testacorsa150]

@info4jon Wow! thanks a lot for your time to give such an extensive answer - it has really helped me a lot. The one i´m looking at is an original example, with relatively low mileage (150.000 km). I have been looking for a long time, and the ones that looked like they have been tampered with, i´ve just ignored. I will be sure to bring your check list for when i have a look at the car this weekend, if it hasn´t been sold - fingers crossed!

[info4jon]

@testacorsa150 Hi!

How a was the car?

I had to do a LOT of searching too! A few wasted LONG journeys to be honest, there aren't many good examples about...

I hope you find something nice :)

[testacorsa150]

@info4jon Hey champ.

Soory for the late reply. The car was sadly a shitbox. The guy inherited it 4 years ago, and changed the oil once! So you camn guess the rest... The clutch was gone, oil dripping from the gearbox, and other sad stuff. I should have found it 4 years ago, when it was still a peach! I am still seaching, but have to get something as a daily runner now as my trusty old citroen zx is eating a gallon of water every week - lol

@testacorsa150

Sorry to hear that.

How much are you looking to pay for a good tomcat?

My gearbox is holding up well after I reconditioned it :)
