alright i'm finally stepping out of the HONDA game... and going back to my MAZDAs again i got 3 of them all with blown engines.. got happy with BOOST! lol they each seen 10k rpm plus.. GREATEST FEELLING EVER! but whatever about that.. heres what i need and i would greatly appreciate to everyone that helps!


I'm about to buy a 3rd gen rx7 wreck'd with only 32k miles for $1,100.. now i'm wanting to take this engine and put it into my 2nd gen body.. 91 GTU that currently has the TURBOII engine in it.. Now, I'm needing info on how to get the 3rd gen engine into my 2nd gen and what will i need to complete this conversion ... I HAVE NOTHING BUT TIME! any links to a write up or anything would help..


THANKS!,

Put an ls2 in it and then you you won't have to worry about another blown engine. Or learn not to rev to 10k.

its just nice to have that 10k.. ls2 = alot of money or nay? how much cutting and converting will i have to do?? i've heard this conversion is a easy one so this is why i'm leaning towards it..

Is it?

Perhaps you could explain why you would want to turn 10k rpm when power is already falling off by or before 8k rpm. Do you have a peripheral port engine that you neglected to mention, and if so, what rpm did it idle at?

my car idle'd around 1500 if dont recall like freaking 3years back.. since than all cars have been sitting in the garage in my parents back yard.. 2 i ment to blow up on purpose just cause i bought the car for 700 and one for 800.. 1 i didnt that one that idles at 1500... my dad use to rebuild rotary engines but he doesn't know crap about the conversion that are done to them... just factory manitance and.. the engine build.. but now since i've done sold all my hondas except one that my wife drives gets about 32mpg THANK GOD! lol my Lexus is killing me on GAS soo i'm wanting to do this swap.. or do you think i should just go back to the turbo2?


also i dont know crap about mazda's... just to let you know that but i've been thru 3 T2 motors... but i swear i love'd it when my dad gave me his T2 as a birthday gift..

If you're worried about gas....Rotary isn't the way to go.

if you get the wrecked FD i'd be happy to try and take some interior pieces off your hands.

Also where is Da Burgh?

dis-guy

hmmm im good i'll keep everything and i dont care about gas saving.. my lexus gets only 19mpg and i doubt the rx7 will get that low... as long as i drive it normal.... now has anyone found any infos?

there have been a few guys who have done this swap, there are a few threads in the 2nd gen section.. search on 13brew or 13b-rew...

any how there are a couple ways to do it... the first way is to buy or fabricate a cradle mount that bolts to the engine in the stock FD positions and bolts to the FC chassis stock location

the second way is to drill and tap the bottom of the center plate for the passanger side mount and then fab up a driver side mount

one other issue is the oil pan and other small stuff
