all of this has been answered. search and you will find all the answers. read through the major horsepower section

sent from my droid DNA while gettin jiggy with your mom...big ***** style

 

sorry but i spend easy 1 week to read all the topic and i find anything for answer my question, i just find other member projet but nobody have a good explain to all my question i think it is quite a different setup to another


I just want some advice, and the search function does not work for me

Or maybe just leave me the link of the topic that answer to my question because I started to feel pain in head with all subjects on this awesome forum

 

Danny,

You are correct that it is painful in your head to get the answers, and you are correct that you could spend a week straight reading all the information.

That doesn't mean that you don't need the information. Because you do. Turbocharging an RX-8 is NOT as simple as just providing quick answers or a few links. It's going to take WEEKS or MONTHS of research and planning if you want to do it right, and then months or years of careful work to actually implement it. If you aren't willing to do the digging for the information, then you simply are not ready to turbocharge an RX-8.

You have to get every single last thing right on the very first try, or you will lose your engine immediately. This engine does not take turbocharging very easily at all, and there are HUGE risks to both bank accounts and hardware.

We can't give you simple answers because the only simple answer that exists is "don't turbocharge". Any other answer gets very complicated. You HAVE to understand every single facet, or you don't even stand a chance.

Start with this subforum: https://www.rx8club.com/series-i-maj...r-upgrades-93/
Start from the top and read each thread with the word Sticky to the left, then keep going and read every big build thread. Most of the informative build threads are on the first page.

 

Yes i know it very complicated is not my first custom turbo project, and i don't want easy answer

I just wanted to get some advice from people who have already made ​​a custom setup or by trial and error. With my old project I could tell people I counsel you to do as his, but his forgetfulness to do that etcc.............. i just want some advice

 

I just gave you some advice. I gather that you are choosing to ignore it.

 

I have a sohn for sale

 

sorry my mistake i just view your link for the subforum its hard to see with a 10 inch screen XD


sorry for that and yes I have taken note of your advice

 

How much you want for it

 

1.
2. 3 if you can make it fit , but for 300hp/250whp 2.5 will suffice
3. 3 is better but for 300hp 2.5 free flow will suffice
4.Walbro has worked ok for me but a series 2 assembly is a better upgrade (for cornering starvation issues) and stock flow is sufficient for 300hp.
5. stock P1 and sec , blue P2 . For 300hp/250whp the stock injectors will actually handle it .
6. Low is much more difficult to build but yields a better result ................ unless you want the bling of a top mount.
7. Cobb or Mazdaedit , depending on where you are ...... mazdaedit would be my first choice .
8.Stock Omp with increased rate (via the cobb/mazdaedit) , no sohn or premix

So yeah , a few of those answers are just my opinion based on 5 years of experience with my own car plus from tuning numerous others of various layout .

 

Thank brettus ! I appreciate
