Im pretty new to the world of rotary engines
i wanna swap a 20b twin turbo into my 04 rx8 what do i need to accomplish this?
thanks

 

To accomplish this, SEARCH.

Oh, and save up about $25,000.

 

i wish this thread was this kind of Deja Vu.






























But it's not.

 

You'll also need one of these that auto-replenishes.

 

The list of required items:

- A 20b engine
- A Turbo
- Another turbo
- A better transmission
- Lots of custom fabricated parts
- A custom oil system
- A custom cooling system
- A reinforced custom driveshaft
- Reinforced axles
- Suspension upgrades to handle the power
- Big brakes to give you a chance at living
- A shop that can do 9 months of labor doing the swap
- A shop that can do the tuning so you don't end up with a paperweight
- A rather large bank account with at least 5 zeros behind a 6 and in front of the decimal point
- A increased volume of gray matter
- A clue

 

^ I like that answer

 

1 million dollars!

 

so i take it i cant make this happen with only 4 grand?
found the engine on tigerjapanese.com for 2,600
will the 13b trany bolt up to the 20b?

 

you cant even make the stock renesis reliable with a single turbo for 4k..

Save another 5k and you can turbo the renesis without a problem. Save another 56k and you can have your 20b + twin turbo system.

 

Why twin turbos? There isn't any benefit over a single one.

 

consider the cost from tigerjapanese.com, shipping, and the cost to rebuild. You can have a 20b, but not in the car.

 

A 20b swap, even NA WITHOUT turbo's is roughly $20,000 in labor.




Turbo'ing a stock Renesis is roughly $10,000, parts and labor.


For $4,000, pay off a bunch of the car, or upgrade your suspension.

 

Because the twin turbo badge/sticker goives u an extra 50hp. Hee needs to make sure he gets one.

 

With 4 grand?
You can get a Cobb AccessPort from MM
A midpipe
A catback
BHR ignition
BHR Radiator
BHR Fuel pump upgrade
a Sohn Adapter
a Racing Beat or AEM/Mazdaspeed intake
A reinforced clutch pedal

and have a little bit of cash left over, but have a more reliable 8 (depending on its current condition) with marginally more power.

 

ok thanks
if i was going to just boost the renesis what kit should i go with?

 

There is this new kit by SEARCH thats pretty good....

 

not again, SEARCH

 

i feel like i've been here before

 

^they are every where

 

OMG... you should totally do this.....


I am subscribing to this thread....


Cant wait to see your progress. Post lots of pics!!!!!

 

 

It's picture time!!! Everyone post pictures!!

 

Short answer, there isn't a kit for the RX-8. Not a single one.


Every single forced induction method for the Renesis is incomplete. The closer to completion a given "kit" is, the more it costs, but even the most complete kits cost $6,000+ and still need modifications to get it to work correctly.


You need to start with a budget of $10,000 for forced induction on an 8. Pay little for the parts, pay alot for the labor, customizing, tuning, and probably engine rebuild. Pay alot for the parts, and assuming you aren't scammed, you will pay less for customization, labor, and tuning.



Go read the build threads and see the nightmare you are getting yourself into, the problems each build has had, the resolution, etc....

 

Lol that's priceless.

 

come on guys, dont be like that. If he gets the engine for 2600 that gives him $1400 to spend on the swap. I think its possible.
