1jz Turbo sizing

[kikwear002]

Im trying to figure out whats a good turbo everyone is running.

Goals are 500hp

my setup is
1jz stock engine
31x12x4 fmic
50 mm wastegate
50 mm bov
tublar manifold
650 rc injectors
3 inch full exhaust no cats

still trying to determine to go megasquirt or someother managment.

looking for some to spool around 4k

thanks for the help

go with a t67 .68 or .58 rear

I would recommend a PFC or Aem to get the most out of your setup efficiently....good fuel,ignition,and timming is most important in my book

I recommend Megasquirt. It's all you need unless you're going to build a race car, and will definately give you 500RWHP easy depending on turbo selection.

You'll need a LOT more with the AEM to get working, and for the price of a new PFC, you can have a Megasquirt II AND buy a laptop, and not need extra software with the PFC.

Buy a Megasquirt premade, install it and be happy.

GT35R FTW

i would get a 63 or a 67

gt35r you'd be pushing kinda high to get those numbers atleast i'd think so

63 or 67 all the way

Eh.... AEM is great. Easy to hook up and easy to work with. Don't buy the hype, it's not as hard as you think.

Although, having THIS really helps:

Plug N' Play harness into the Supra. You only have to run 6 individual wires for the injectors to convert it to sequential fire. That's a no-brainer.

On topic.... A nicely built 4067 dbb is a great turbo on the 1JZ. Good response and it will make your power goals.

for 500whp, a 63 or 67 is alot bigger then you need.
Who cares how high you have to push it, if its in its efficiency range.

Chris, Does Richard sell those off the shelf like that now? Last I talked to him, there was more work to be done to convert over to AEM.

AEM IMO is alot harded to tune with then the other systems out there. I played with the interface and its just alot to take in for a newer tuner. There is alot of screens to get lost in and a lengthy config process before you get started.
But it deff has its perks once you get used to it.

 

[s14eva1]

Yeah...+1 for that conversion harness


Chris,are there certain model aem boxes you recomend?

30-1100. Supra Turbo box.

Richard sort of makes the harness, but he isn't advertising it. The harness is plug and play now for the exception of the injectors. You have to wire up a resistor pack like you were doing MKIV injectors, and you have to run the 6 injector wires over to the injectors. This is because the AEM runs sequential fire and our engines are configured for batch fire. Beyond the 6 wires, it's a plug and play deal.

As far as tuning, the AEM looks like it is very complex, but honestly they have improved it greatly over the past 4 years. I would recommend it over any other standalone at this point.

Thanks guys, I think im going to go with the Gt35r. Along with megasquirt. I've been reading there is something special you have to do withg the mega squirt to make it fire the coils correctly? anyone know about this?

Yeah it;s kind of difficult. I'm trying to duplicate my setup right now. I'm sure I'll do it soon enough but it's not a priority. As soon as it's done I'll be posting it.
