Blitz Turbo Booster For Twin Turbo

goodoldgrandad · August 29, 2006

I have just bought a Blitz Turbo Booster (Dual solenoid version) and the fitting instructions are very poor. As the V300 has the Supra engine I did look for clues on the Miv club site, but as the engine bay layout is different I was hoping to find some experience and hints from V300 owners before I start open heart surgery!! If anyone has any photo's or can identify where the best places are to splice in the Boost Controller plumbing it would be very helpful.

I hope you've picked up a Boost Cut Controller too to enable running higher boost :).

No not as yet. I planned to be limiting the Boost with the Blitz Controller to that recommended on the Mkiv club site for the standard Supra TT engine without re-build (limited to 1.2), and understood the Bliltz unit had user settable safety cut limits to protect against over boost problems (so you need not have a seperate over boost cut controller often recommended on other manufacturers units). Am I wrong? Do I need to install a seperate cut device as well? Unfortunately the Blitz instructions are poor.

Any suggestions, installation help, or set-up advice would be greatly appreciated.

I'm not entirely sure on the specifics of the Blitz unit so unfortunately can't help you there :(. Gaz or Yoshi might chime in with some more info on how to wire it up? I think Yoshi has a Blitz EBC too :).

Just thought - if you meant am I fitting something to over-ride to normal turbo pressure sensor to prevent the management system shutting down the answer is yes - I'm going to use the Greddy fuel cut voltage regulator.

I'm sure you don't need a GReddy Fuel Cut Controller...it's the Boost cut controller you need :).

My mistake - I meant the Turbo Boost Cut Controller (not fuel cut device), which I've got. I'm just seeking clarification of the connections/wires on the Aristo TT as opposed to the Supra TT. I still can't find the ECU in the engine bay!!

Anyluck Gramps?

No !! Can't find the black plastic box the electronics are in. Still searching!!

Is the ECU not in the black box with the arrow pointing at it in the pic below:

That's where it was in the IS and the box looks the same?

goodoldgrandad · September 4, 2006

I'll have a look - it's the only one left to open!!

aido · September 4, 2006

Cool, fingers crossed that'll be the one mate - you should see all the wiring harnesses when you pop that lid open, think the ECU also just slides out, can't remember if Zee's had any screws or nuts hiolding it in when we were working on that?!

Hope it is in that box as I'll have to go through the same things you're doing at some point :)

Yes spot on - in here under a white plastic cover. There appears to be two different terminal layouts available, so I've traced the wires back from the Turbo Sensor. See the post on the Greddy query for all the details at:
