Been considering fitting a let in my mk1
What's involved in doing so ? I have a c20xe in mine but really
Like the thought of let lump . Smile

What kind of money does one cost ?

Not really any different to an xe conversion other than the extra piping for an intercooler and different exhaust.

So pretty straight forward then ?? Is there a big difference in power ?

Depends what you want from the car.
A c20let will be much less reliable, parts are expensive, ect. they are obviously much quicker but as I say depends want you want from the car.

Tune the xe motor will be a lot more fun with 200hp NA.

What would be the cheaper way to gain more bhp

A let will put a smile on your face every time you plant your foot, but an xe will probably be easier to drive fast as you can put the power down.
The main problem with a let is finding a good one, their all quite old and likely to be abused, I know the same can be said for an xe, but hardly anyone will have a std let so the components come under more stress.

I had a let for several years, I do miss the craziness that happens when you plant your foot, but I'm now after something I can drive fast without the crazy.

Jon ,You say an LET will be less reliable then advise a tuned XE instead ?? I know what I'd rather have !

Calibra C20let

Astra xe

There is a big difference in weight to consider too.

Thanks for that Lloyd Smile

I thought the let
0.60 would had been faster than that . Has anyone ever super charged a xe ?? I've seen a mk1 escort that had been done rapid comes to Mind

I havent recommended anything.

If you want a c20let, just do it.

From my little experience 200 bhp in an astra mk1 is more than it can handle . All the power from the engine should go to the road. If you fit a LET then its better to uprate the cars structure , brakes suspension etc etc ..
Its my opinion better to have less but on the road with 100 handling than more without handling and control.

Mines 290bhp fwd with an limited slip diff which is highly recommended for a turbo motor. So it's not just spinning up 1 wheel.
