The TO4R is a Garrett turbo that was originally built for HKS to sell. You can now buy them from a number of turbo dealers that sell Garrett products for substantially cheaper than HKasS offers them.

Not on a FD, no. Saw 640.XX on a Mustang.. Don't have a sheet anywhere though..not my car. TO4R.com has quite a bit of info on the turbo. Supras of course.. I know the turbo will do 600. Whether or not the car will hold up is another thing..

Are there any 600hp RX7's? Other than the full drag ones.. The Scoot one did 700 something.. but that was a T51R-SPL

I rode in a friend's car last night, that has this turbo. He is having problems with fuel pressure. But, 15psi felt damn strong. It comes on mighty quick too. I didn't notice the lag at all. Maybe I was just overwhelmed though.

do know where it was fully spooled by? I'm thinking about getting this turbo, but i read about it being kinda laggy.. https://www.nopistons.com/forums/pub..._DIR#>/sad.png so i might get a little smaller t04, but im not sure yet...

So the compressor on the T04Rs from suppliers like cheapturbo are the same as the HKS versions?

Laggy https://www.nopistons.com/forums/pub...R#>/violin.gif

This was my car I took rotary speedster for a ride in.

The other night I logged a couple of run's in 4th gear, In one of the I went WOT at 2900rpm and at 4000rpm's the boost was at 15psi. The other run WOT started at 3600rpm and at 4200rpm 16psi. Its a little different in other gears. But that just describe's the boost threshold??

Describing the lag on this turbo I would say its similar to my non-seq twins with the wastegate enlarged too big(doh). Anytime the revs are over 4k the boost comes on very quick. example 4400rpm 3rd gear go WOT @ 5100rpm 14psi.

Hope this helps some and dont confuse you to bad. https://www.nopistons.com/forums/pub...IR#>/wacko.png
