I used to think throwing the LS1 in the FD was blasphemy. Now I'm starting to think I wanna try it. Unfortunately I'm too lazy to do the work myself and the whole bill is roughly $12-13K for labor, LS1, and T56. But man, you can't really go wrong with an LS1 FD IMO. Low-end torque (wtf is that), reliability, kick-*** aftermarket support and only slightly ******* up your weight distribution from 50-50 to 53-47.

haha right on but let me correct you because i corner weighted my car and my friends stock rx7 and his was 53 front/47 rear and my LS1 was 50.5 front/49.5 rear. your results may vary. i have it video taped on my site.

I'm not calling you a liar but that simply dosent make sense. How does a heavier engine and tranny equate into less weight than the front of a 13b. Does all the other miscellaneous stuff under the hood of a 13b car really weigh more than an LS1 car?

it wasn't an apples to apples comparison but it goes to show that a well executed swap won't affect any handling goodness.

my battery is moved to pass side bin. it had PS, AC and ABS removed

The LS1/2 is an aluminium block though? When you count in all the junk for the 13B and turbo's etc. does'nt it come to be 50-100 pounds more for the 13B? I read it somewhere, I forget where.



I for either one honestly, but what do I know, I don't have an FD.

I'm with UnNatural, Im 100% against anything but a rotary in an RX car. I don't see the point in doing this swap, If I want an LS1 powered car I'll go buy a Camaro.
