Try www.v8roadsters.com for all the mounting hardware. Front and rear subframes, oil pans, steering conversions, oil pans, radiators, headers, etc. Very high quality stuff!

That dude did it with a LS1, but pretty much the same. Ask him for pointers, he even has the gauges working in it.

Seen subframe mounts and custom RX8 LS headers for sale by a reputable shop in New Zealand, http://www.racefab.co.nz/ click on mazda parts.

They've done a few LS RX swaps.

This is definitely the best way to get an RX8 moving again, have fun not rebuilding it, or going through the usual muck-around operating procedures, needed to keep a rotary happy for general use. Love them, but they will never be made again for good reason.

If you're going to make an audacious claim like that, you better back it up with evidence. No one wants to read mere hearsay.

Dumbass posting irrelevant information, then getting butthurt on being called out. Why not go out a post a link to a g-body ls1 swap while you're at it?

Default Rx8 ls1 swap

All you need to do is go to the rx8 forum to find out about Hinson.customer support sucks,they take forever to send you the parts.i called them a bunch of times about their kit,never got a straight answer,was told they would answer my questions by email,that was 2 months ago.the guys at rx8ls1.com are great I can text them with question,and they actually text you back!

Yeah...I'm the one that's "butt hurt"...


You win Nick, I'm going to bow out now. You've obviously intimidated me with your superior knowledge of the LS world.

Oh yeah, speaking of butt hurt...I hope you make up with your boyfriend tonight so you feel better tomorrow.


(OP, I apologize for mucking up your thread, Best of luck with your build.)

Very funny did you sell your car yet!,I read all your stuff also,nice car.the only problems with the rx8 is the can bus system,and the rear gears.other than that it's not a hard swap.im putting a 8.8 irs rear in the car with 3:55 gears so that problem is solved.

both are easyish hurdles. can bus can be overcome by using the RX8 pcm. in order to have a CEL i wired in my own LED into the cluster. same for the Cruise light. i deactivated the unnecessary lights. the RX8 rear is very stout. its an FD rear. 8.8 is great for the gear selection. I am installing a set of FD auto gears which are 3.90. perfect gearset for the weight of the car. I still have it. its currently getting a bunch of upgrades like built trans, wheels, cam, pcm relocate with new harness and the 3.90s. i averaged 24ish highway mpg with the 4.44s.

get on NoRotors. lots of smart people there. avoid RX8Club. bunch of.whiney pussies on there. basically the swap section is.full of guys with stock cars trying to make the world love the roturd. i used a complete Hinson kit and paid over $5000 for it. i only bought it bc it saved ALOT of.time and guesswork. plus i like using properly built parts. i wouldnt use them again. components are tip tip but i can go on and on about the support. the instructions are useless. if you call them with a question they try to sell you something and when they find out you dont want to buy anything they put you on eternal hold or "ill call you back." the guy i bought the kit from waited 8 months for the kit to be.built AFTER he shelled out big bucks on the kit. in that time he fab'd his own stuff. i would use V8R or dare i say Stephens kit. im not impressed with his.kit though as it looks.like its made from home depot steel. and his parts are very clumsy and not very well designed. even intermediate fab skills should be a requisite for someone doing a swap. otherwise buy an LS car.
