Fc rx7 turbo. Teach a noob please

slammed 66 · August 09, 2011, 10:03:36 PM

Hey fellas.

So... I\'m about to become the owner of an fc rx7 turbo.

I\'ve always wanted one but have always been massively scared by the black art of rotaries.

So what do I need to look out for?

I\'ve heard of people adding a little oil to their fuel to protect the rotor tips. Is this advisable?

The car in question has covered just over 100k and I\'ve no idea if it\'s ever been rebuilt. Is a rebuild expensive on these? I should imagine it\'s highly specialised.

Now my favourite part....

Steps to more power. How should you go about getting more power without instantly exploding it.

I hope all of this hasn\'t already been covered a million times already.

Thanks chaps

Ross

Hi there,

Is the car standard? Is it a FC3S turbo, or turbo II? Do NOT just whack the boost up to get more power, you need to make sure that the fueling and cooling is up to scratch before you can get more power out of the car.

The car is 20 years old, so certain things like cooling and ignition are getting old and so you should think of replacing and uprating those parts.

General things are to regularly check and change oil, also only use good high octant fuel in the car.

It might be worth getting a compression test done on the engine to find out how strong the engine is.

Rebuilds depend on what you get done, most people get bigger ports and changed certain bits when putting the engine back together. Rebuilds are from about Â£1-3k depending on what you want to get done etc. There are many rebuilder for rotaries, or indeed you could rebuild it yourself, its just a few plates, some housings and a few seals and long bolts lol

Basically, if you look after the car and don\'t be silly with it, the engine will last ages, mines on 89k miles, still got very good compression.

Remember that the OEM turbo and fueling is only good for about 0.9bar or about 275ish safely.

Main issues with the engine going:

Running lean on boost - not enough fuel will mean detonation which will take out a whole rotor or housing (Â£Â£Â£s)
Ancilary failure - cooling usually radiators or old injectors or igniton - overheating will mean water seal failure.

Are you the same Ross that was on RCC?

Hi Brett,

Yeah that\'s me dude, how you doing fella? Been a long time.

By the way, the car is a turbo II according to the script on the inter-warmer

Oh and it\'s standard too other than an airfilter. It\'s actually the Â£800 vert in the sale section which reading back over the months may have had boost issues at some point.

What are your plans with it then? You would need more power than a coupe to have the same acceleration due to the 2 extra floorpans and weight the cab has, on the up side, they don\'t rust as easy due to the extra metal!
