rx8 20v turbo motor swap

[tinker-27]

im not changing it at the moment im going to see how it is , they rev to 7k if needed but depending on spec . the vag motor will make way more torque so we will see how it drives ( im sure it will be good)

Great project. That engine is easy to update and get more power. And dont need massive amounts of money to do it.

I think it would be nice allday car. I wouldnt worry about finaldrive. You can think it later, when car is ready and you can see what kind of mpg itl do...

My vote is to keep the engine bay free and mid mount it - I was looking at one of these for a mid engined car project, just mount the engine in the rear and the box is a front transaxle meaning that it would still be rear wheel drive, also the Audi A8 V8 engine apparently bolts up fine to an A4 front transaxle

I\'ve seen a couple of these conversions now, if you don\'t like the rotary then they\'re okay.  Personally I\'d never change out my rotary engine for a piston engine, since it looks like you\'re doing it to a 192 then with a 7000 rpm redline you shouldn\'t lose out much in top speed, if it\'s onto a 231 then you would since that needs all 9000 rpm to make its top speed.

Whilst i love your inventiveness and ability to perform such conversions, i just dont get it! The soul of both the 7 & 8 is the engine, if you want something uber reliable and bullet proof, dont buy a rotary!

Well an RX8 with a blown engine is worth about £1500, cheap car to have as a project, don\'t really like the rensis engine, rotaries should either be heavily ported or have a turbo fitted, they should be easy to get a lot more power out of.

Understood, but, add a conversion on that and your way over a rebuild, then you have to factor in, what someone is prepared to pay for a rx8 with a conversion! Sorry, bar the fun aspect to "tinkering" to do the conversion, i just dont get it

Will be watching with interest

rx8 are heavily ported dude. ports are so big that even racing beats porting templates dont reomve much more material.

RX-8\'s need a Greddy turbo kit or a supercharger conversion is what he meant to say.

[Grant Monkhouse]

RX8s need the engine throwing and a single turbo REW bridge port motor throwing in there. all electronics thrown + interior all setup for a monster go round corners race car, maybe not too comfy on the road though??

[BlitzBoy]

you can turbocharge a RX8 Renisis engine quite well no need to chuck it in my eyes

i know, having seen turblowns power production theyre great, but hes using E85. not something that is easy to get over here now

regular pump gas + AI with window washer fluid in the small tank should provide close to the same power outputs.

Turblown setups are producing peak power comparable to majority of turbocharged 13Bs. Honestly, 90% of Rx-7 people didn´t breach that self imposed limit of 15 psi boost, limiting them to around 400 rwhp. Turblown GT35R kit on Renesis does it at 10 psi...
