Hey guys. So a friend of mine bought a 2004 RX-8, 6 speed manual. 30,000 miles on the chassis, around 15,000 on the new engine. The engine has been replaced. Problem is, when we started it, the car just died after 2 mins of idling. We started it back up. So that was fine. Then something really weird was happening with the throttle. So, every time I rev it, the engine would rev up to like 1200rpm, drop down to idle and then rev until I let go of the pedal
it's like I'm blipping the throttle right before I rev it. The needle bounces up and down once, and then revs all the way until I let go of the pedal. This happened in neutral btw. Just wanted to know what you guys think.

I'll try cleaning the throttle body. Thanks!

AFR is air-fuel-ratio. So metered would be the actual ratio ex. 1:1.
The command would be the amount that is executed. So this is out of my field of knowledge. But I broke down the words to deduct this^^^^

So commanded is showing it's all ok and metered is showing the car is running lean ![Frown](https://www.rx8club.com/images/smilies/frown.gif)

So som3 Google research returned with.....check the MAF. Have you cleaned it yet? If not ONLY use MAF cleaner. Also check to make sure the connection is good. It's secured down. Look for leaks in the intake accordion or around the intake. From what I read, MAF reading would cause your AFR meter to run differently from your command due to an obstruction in your MAF's reading.

Ok. Serious (although admittedly dumb) questions. I have a 2009 Series 2 6speed manual RX-8 and am thinking about an Engine swap. Originally I was thinking of swapping with the 13B ReW (the "w" indicating the presence of twin turbos) but to my understanding the twin turbos of the REW will not fit in the Rx-8. So if it has no twin turbos should I just get a plain 13B RE (without turbos) and if I got that would an originally non turboed 13B RE be able to accommodate a single turbo if I added one or is the 13B RE not designed to handle the production of the turbos found in the 13B REW?
Aside from all of that, what is the difference between the 13B RE and 13B REW? Is there a difference in the exhaust ports and strength of the material etc?
If I were to do a swap, what all would I require?

But to start
Do you have the ample time it will take? Tools? Knowledge of the 13b itself (I doubt)? Fabricating skills? Money. About 8kfor the bare minimum I would say. If you did all the work yourself. You can keep things like the PS, throttle body and ac, transmission otherwise, you will need to replace alot. Do some reading, this isn't a very simple answer.

This is a question where you should look into some ones build. Firecrans for ex. There is way to much to list for this thread.

Does it do it with your foot on the clutch?
