hey guys,

 

just some quick questions,

 

when i get my blacks i want to upgrade my ke70 to a turbo but not the 4K so i was thinking a rotory or a 4AGZE...

 

what is cheapest?

what is easyest?

what is more powerful?

what rotory is best?

how hard is it to get a rotory engine convo engineered?

 

sorry if this thread annoys anyone, its probly been asked so many times,

any help would be great,

cheers, KE70YO!

what is cheapest? 4agze

what is easyest?4agze

what is more powerful? depends

what rotory is best?depends

how hard is it to get a rotory engine convo engineered? ask an engineer.

 

if you want turbo, the rule (in QLD at least) is such a way that a 13B turbo is to big for a ke70, but a 12a turbo is ok.

 

so you can either have a 12a turbo, or a 13b non turbo.

 

12a turbo are pretty rare in aus, and they are all stuffed by now anyway.

 

in fact almost all 12a's are stuffed by now, and you can't get 12a housings new anymore, though a few place around are machining down 13B plates for use in 12a, at a cost.

 

12a's are also carby from factory, so its alot of custom work..

 

you will need to do ALOT of research, 12a's mount from the front of the engine in rx7's, but there are ways around this. as you want to get them to mount from the sides if you can, so you can just mount them to your existing crossmember.

 

in summary to put a turbo 12 rotary in you car:

 

custom engine mounts

custom gearbox mount

custom wiring

figure out what intake manifold you are going to

figure out how you are going to setup you EFI system, staged injectors? what CAS are you going to use?

figre out what ECU you are going to use.

custom intercooler piping

possible custom turbo manifold

exhaust

decent fuel system (surge tank etc)

custom tailshaft

bigger differential to handle the power

 

 

 

for 4agze

 

convert everything to AE71 spec, bolt in 4agze, intercooler piping, fuel system, wiring, drive!

 

which one is better?

 

4agze for ease of installagion and happy drifting for a few years

12a turbo for the awesome power and response that is possible if you do it correctly.
