turbo project/v6 stock internals limit?

[jhenty]

Alright guys Im going to turbo the beast, you may have seen all my supercharger and other stuff for sale in the for sale forum. Im going to start with a simple 4psi boost on a t3/t04s hybrid, running smt6 for engine managment with a single extra injector placed before the throttle body. Im going to tune my way up from there and eventually go all out this summer with forged internals.

Now that I let you know some of the project details, does anyone have any idea what would be the psi limit on a turbo like this? Im going to play safe and not go further than 6psi before I rebuild the motor. I should make power around 3,000 rpms when tuned correctly and EVENTUALLY around 330whp at 10psi.

Project starts in two weeks pending the sale of all my current stuff.

I'm going to guarantee that you will not hit 330whp w\ stock internals that don't have broken piston lands or other damage... your trying to attempt things that people have in the past... If I were you, and you don't mind a little damage to pistons, then try to push the stock internals.. otherwise, I would just jump straight into getting forged internals...

not to be a damper on the fun... i love modding this car platform, but its just so hard w\ the engine that is in place as is

[hskrsolara]

just go all out the first time so you wont have to redo all that work later.

[jhenty]

im not going to up the boost until I forge the internals, I wont go higher than 6 psi without forged and Im only starting with 4.

I'll share this info through personal experience from me and joeB.

6psi on stock internals is safe. Proper tuning required.

7psi - 15psi on TRD s/c is safe with just forged pistons and stock rods.

20psi on forged pistons and stock rods.......RESULT: bye bye rods.
(I've never felt so much power in my life! Too bad it only lasted less than 10 seconds)

[jhenty]

hahaha 20 psi, that must have been fun while it lasted. Thank you for that information, exactly what I was looking for and what I planned on doing. From what I've heard the t3/t04s turbos can put out around 400bhp at 10psi on an engine such as the 1mz, but I wouldnt go anywhere near that until I get the engine rebuilt. What compression do you suggest when i do rebuild....8.5 or so?

8.5 to 9 should be fine. I'm running 9 on my setup with up to 23psi.

Rizal stepped in and got everything answerred there for you. What size is the trubo you're going to be running? Let me know how everything works out. Next to a 2JZ-GTE engine swap converting to RWD, turboing the 1MZ is on the top of my list of things I'd love to do with my Solara. But unfortunately, the turbo kit alone would cost a couple grand, then getting a shop to fab up the piping and everything, on top of the neccessary upgrades like injectors, fuel system etc. You'd want to run the thing rather hard, so you need new pistons. Then you're pretty much doing a lot of work for restricted gains if you don't get a P&P, and full exhaust. Then standalone ECU management and tuning.

It just adds up to be so much so quickly.

And this is why my car is sprayed .

Good luck Jhenty, I can't wait to see how things turn out.

you have that beast runnin perfect yet? I so want to see some videos of that monster

[Mandarinsolara]

could the 1mz fit 13.5:1 pistons without worrying about interference

i think 13.5:1 would be lovely accompanied with 8-10 psi on race fuel

[SC V6]

ummm... yeah, I doubt thats possible

Gimmie two weeks. In the world of custom fabricating that could mean a month or a month and a half. I'm getting impatient too bro.

[jhenty]

rizals setup is a lot more complicated than what im going for, he uses a HUGE turbo and hes going to be making more power. Im going to be custom fabbing everything myself with a different sort of fuel system than most are used to.

Im going to be runnings an extra injector before the throttle body (850cc) that only operates under boost. I'll probably have to convert to a return style fuel system when i start increasing boost anywhere past 4psi. Also using a walbro 255lph pump.

Turbo is a t3/t04s 60-1. Fuel management is going to be handled by a smt-6 piggyback. This will control the extra injector, timing, and modify the stock fuel maps. I'm starting very conservative because I know I will need forged internals shortly after boosting because I'll want more out of the car.

If all goes well hopefully I'll consider making a few kits for those serious enough about them. There will be problems along the way, I know this, but starting slow and being optimistic about it will help me achieve exactly what I want with it.

Thanks rizal for the info and thanks everyone else for the support. I'll keep you updated.
