Hi all, back last year I purchased a rx7 hoping to learn a thing or two about them on the way, but nearing the end of the year my to4r decided it dint wanna play ball and gave up the ghost leading me to try and find a new turbo something along the same lines or maybe a bit bigger but want some advise or recommendation's.

Current spec is
Aggressive Street port
Hks manifold
44mm external wast gate
Screamer pipe
Hks down pipe
850cc primary and secondary injectors
255 in tank fuel pump
Blitz cooler with alloy rad and 2 oil coolers
Along with a lot of other mods clutch box Lsd e.c

The to4r originally on there was a hks to4r
Compressor side a/r is .70
And hot side is .96
Any thoughts on advise on new turbo or a newer more powerful one to upgrade to ?? Any help would be appreciated thanx

 

If you have that turbo running on the engine then you would want to replace it with the exact same size turbo.
That way you do not have to get the car re-tuned.
By the way you did not mention any ECU.What are you running to control this setup?

 

I don't no the ecu as the car was an import they did not specify what system it ran but it's not standard I'm still finding new stuff on the car hah ohh left a bit of a big thing out as well it has a good reddy pro spec 2 controller. Next time im down the unit ill have a good look. I have tried looking for that exact turbo but can't seem to find one any were as it's a very old unit. Ohh and thanx for the reply

 

If you find the wheel specs or measure them and use the same size of Compressor and hot side then you pretty well have what you had before.
It would just be another name of turbo.

 

I'll have a look tonight thanx bud

 

Ecu is a hks fcon v pro and also found a new cartridge with the exact dimensions of the old unit just a more modern one will be ordering this along with a new anti surge compressor housing next month .
