Starting my S1 XJ6 LS1 swap

Agreed: bumperless is best!

Could you imagine placing a bumper on this? Bumpers are for golf carts and tug boats.

fresh off the dyno. came in a bit lower than expected. no where to go but up.
needed a baseline and needed it to run/drive so i didn’t have to keep a foot on the gas pedal at stoplights.
was dyno’d in second gear. shop said they have seen too many ls conversion driveshafts come apart in 3rd on the dyno.
so add maybe 10-15 hp for not 1:1 gearing.
the stock intake and stock exhaust are killing the power. next will be an ls6 intake and some custom long tube headers and 350-375-ish at the rear wheels. then a set of heads.
when the shop puts up the video on their you tube channel, i’ll put up a link

got the windows tinted and the stock ls1 intake swapped out. next is custom headers.
that ls1 needs to breathe

That is one lump extremely well done.

If you need a Jaguar SI front bumper, you may want to contact Peter Crispen. I believe he may have one for sale.

thanks again for the kind words.
and i have the front bumper, i just prefer the look without it.

Seems as though Boss Gunnar did it. I can live with it. I can read up here and visit regularly.

Wherever posted. A pleasure to read and admire…
