Title: Make a Fwd LET (Part list?) :P
Post by: Round_Lake on November 05, 2017, 22:23:28 PM
Hello mates Emil here from Sweden!
I own a Sydney Irmscher cali with the c20xe and want to get power power in the car to make it match my GT dreams I have for it :)


I have considerd a V6 swap but want to se if a LET build maby is easier to do.


What I would love to know is what parts would be needed to make it happen, will not convert my c20xe but insted I rather buy LET parts.


So do I only need a few parts or a hole LET drivetrain?


Also can I stick with my gearbox as I will not go above 250hp or is a F28 a most?


Why Im a bit scared of to do a v6 swap is beacuse I dont want to swap the ECU and electrics as Im not pretty good att it.




Ty for all answers as they will help me a lot, everything is welcome :)


Regards Emil

Any gearbox the XE used the LET can also use, ie F16/18/20/28

Ah okay but can the F20 hadle the power of a LET with say 250hp?

A friend of mine has a vectra A with 290-300 hp and uses f18 or f20 can't rember, so 250hp will handle with no probelm

f18 wide ration , is basically the same as f20 , i think slight difference on fist and second, and clutch plate assembly  are different, but they both work
