no

rg200amp

im gonna say no, but..........

with ehough money, time, and money i guess

you would need to fit new trans, clutch, ect. . . . . . . . .


and you would need to move everything
why not just buy a vette

I've seen more Ford engines swapped into Mazdas, usually a 302. I think the reason was oil pan clearance, but there is no way to know without getting an engine and measuring everything, then you don't know until you try. I would think you'd get front to rear and left to right clearance problems, plus the LS7 being too tall.

Bingo.

If you really want to get exotic and try something that would fit, look for a surplus Allison Model T63-A-700(250-C18) Gas Turbine Engine. 325 HP out of a 140 Lb motor that measures 40" long by 33" diameter. No radiator needed. Probably better with an automatic.

just let it stick out the hood. custom hood

Georgia8er

A custom hood would solve the height problem, but not the others (if they exist). I do like the gas turbine idea, but where do you vent that super hot exhaust?

If an Ls1 will fit in the Rx8 so will an Ls7...same exact block with different technology bolted to it.


Use the Search Button...I know I read somewhere someone had it done with an Ls1 or Ls2.

A few ppl have talked about doing this swap a while back but I guess they were just blowing smoke cause we haven't seen one yet.

Go the Major Horsepower forums. I've started a thread about this. There is a well known company that does LSx swaps into RX-7s and 240SXs looking for someone wanting to do this. They build kits to make the swaps bolt on. This is definitely not DIY without.

Is it possible to swap a fc3s into rx8 cabin........?Any after effects pls advice........

BlueRenesis82

no way are you going to fit a whole fc3s into a rx8. you would totally ruin the interior and gas mileage would get worse

kent_sg

Coz my apex seal break and i tot of changing to fc 13b turbo. Its not the whole fc in rx 8 but only th engine mounting n the 13b turbo with microtech.pls advice if any after effects like the mentioned gas mileage and wat else..........

If your going to do a high power engine swap with the 8 just go for a 20b mazda eunos cosmo engine it'll mate up the stock tranny

kent_sg

From the place I'm in, 20b is not available. anyway wat's with the 13b turbo (Fc3s)? Is there any Problem with it in 8? Are there any sucessful 8 with 13b turbo (Fc3s) engine swap.......?

or just buy a mustang in addition. I can tell you as Cobra owner as well that the Cobra fails to scratch any itch accept for speed and power. That's about the end of it's entertainment.

If you're REALLY pushin to do a swap, go 3-rotor or 13B TT...still a hard swap but not NEAR as hard as an LS7
