I know i asked this ealier but i can't find my post....ok im going to do a vacuum hose job by myself yea im 18. and im going to school to become a mechanic and i love rx-7's so i want to know everything about them and be able to work on them like nothin. but yea i have done all my other mods myself and car runs great. but yea i need to know what exactly to do when i do the vaccum hose job so i wont mess anything up and what to take off. and one other ? i dont have my power fc tuned yet but i have mods that people told me it would be ok without it being tuned for now. but my other ? was that if im running 96 c sometimes on mly temp is that ok or to high and if so would a aluminum radiator help that out ? thanks alot guys. peace out

with the vacum hose job make sure to take your time with it and dont rush, if possible go one hose at a time so you dont confuse the lines, and yes an aluminum radiator will help, also try to make some ducting to make it even better.

96 c is perfectly normal. Having a powerFC telling you the temp all the time made me paranoid for a while too.

thanks and I just got done reading something and it says not to use syntethic oil in your rx-7? i have used it twice on my car and it runs fine....i dont get it...

That's been a highly debated topic on this forum. Some people think synthetic doesn't burn as cleanly as dino oil and can cause problems since oil is actually injected into the combustion chambers. Personally I use castrol 15w50 and change it every 3k miles and never had an oil related problem.

I believe you can run sysnthetic oil if you are running a midpipe, other than no because if you are running a cat it will get clogged since synthetic oil does not burn like regular oil.

allright thanks guess i should get a midpipe.. haha

This is NOT TRUE. What will kill a cat is disconnecting the air pump.

If you get a midpipe you'll also need to add a manual boost controller to prevent boost creep. And, you'll have much more noise (maybe cop issues) and the nasty odor of raw exhaust.

Hi-flow cats give you most of the hp increase of a mp without those problems. Plus you can pass an emissions test if the rest of the car is running right.

These threads should help you out.

NO BOOST CONTROLLER WILL STOP BOOST CREEP!

When will people stop posting this crap?

ok well is there any high clow cats on there that are cheaper than 425 at the rx7store? and yea if i do get a midpipe ill have to tune my pfc right? but i would rather go with a highflow cat just dont want to pay 425 .

Pardon me, I got that wrong. But with a midpipe you have to be watching boost.
