300 is possible but ur need to spend a little more to make it reliable also. if its going into a corsa i would suggest a rebuild 1st as it will save money in the long run

and an 20XE corsa is the best car for her to learn in?

So, 300bhp, what phase is that?

U dont want a Z20let as it costs more to get to those sort of levels!

u want phase 3 EDS £400 odd quid
or Vmax evo 5 about £400ish im sure

£150 bigger intercooler, £110 injectors, £90 fuel pump, £681 (delivered) Matheus turbo kit

can also buy copies of the chips on the net from various places at a fraction of the price!

Depends condition of the engine really!

my mate managed to get a LET engine with an f28 box and tx box for about £200

fair enough the wiring was burnt and he got no ECU, but the engine was in bloodu good condition.. until he put 26PSI of boost through it and done the woodruff key

anything modified from factory spec is not going to be reliable, people just expect things never to break.

acclerated wear driving style and servicing.

It is often quoted that a good well looked after and regularly serviced LET with a good strong kkk turbo will be able to acheive 300bhp with only so much as adding a FMIC to lower inlet temps and obviously upgrading engine mangement.

There is someone on club calibra running phase 3.5 on a lower comp pistons and has been for 2 years with no mishaps.


Its all in how you treat it IMO.

Mines totally standard bottom end and head. Gets loads of hammer. But is also looked after well.

Not let me down yet!

Its about to come to bits though.
