(((So I know ill get a lil crap for this but... Ive been searching. EXCUSE THE CAPS COMP> ERROR IM LOOKING FOR THE CHEEPEST SAFFEST STARTING POINT WHAT DO I HAVE TO HAVE AND MAKE THE MOTOR SAFE> Statring with the greddy turbo kit. fuel enj? coils?

 

skip the emanage and go straight for Cobb ap by mazdamaniac.

 

Cheapest starting point is to read everything there is on turbo kits and understand what you are getting yourself into
Making the motor safe ...... hard to know what to advise you here . You are always going to be at a higher risk than N/A . It mostly comes down to tuning .

That good set up. I agree get the cobb from mazdamaniac

 

My plan is when I go turbo is to upgrade my engine seals and rebuilt it.. Cuz I read somewhere rx8s are not made for high miles

 

nothing wrong with stock internals up to well over 300whp .
Good tuning is way more important

 

Ya good tunning is best and to start out with low boost. And then work ur self up..

 

Although the emanage sucks, that upgrade kit is included with all current GReddy kits brand new. But you should get the AP anyways.

And you don't need the GReddy pan.

All the answers you seek are elsewhere on this forum. Utilize the "Search" function

 

you probably wont need new plugs running on the stock greddy kit either, unless you really crank up the boost. If your going to just run stock boost or lower than 10psi, put that money twards new coils. I for one wont even install a boost controller untill i get new coils and fuel pump. I dont want to be tempted to turn it up!

 

Thanks for all the help

 

I also agree on the AP and READING AROUND THIS FORUM!!!! As for the motor being safe....tuning like BRETTUS said is the most important thing when it comes to "engine health"
