Turbo BS Thread

My question is, how many psi will the stock computer handle? If I decide to turbo instead of engine swap.

 

If you plum it in after the cat, back pressure shouldn't be a big issue.

 

Yup did a DW 200 and added the external filter. I also did the better fuel tubing for the pump

 

I believe the ecu can be tuned now with ovtune

 

Even the 2nd Gens?

 

The 2TR is getting shit on by them. It's up to the individual to make all motor (best we can) or turbo boost and R&D on our own. Read as: they're only giving attention to the V6s and said there isn't enough interest for 4 banger, when there definitely is.

 

Hmm. I wanna turbo it, but I want to keep the reliability of the electronic, and plus I have no idea how to tune

 

I said in here that I plan to get the LCE header, and I will soon enough. 100% certain.

Would upgrading to the Walbro 255 be a good idea as well too? Or similar fuel pump upgrade kit? Suggestions and ideas welcome.

Trust, I'd rather boost mine and run a reliable 7psi on everything as stock as I can stay to be budget-friendly (cheap AF!), because I'd be willing to buy a nice turbo and accessories to make up for keeping stock internals and ECU.

EDIT: I also off road several times a year, so that's a concern of mine, too. Want something useful on the low end, and strong enough to handle the abuse and mud.

 

Once a few of these members with a 2TR get theirs running on a Haltech, they could possibly throw you a base map. You'd need one as well though.

 

It doesn't understand PSI. Only Mass Air Flow, in grams per second. MAF sensor based.

The Map-ECU3 can kind of help, but your ecu is reluctant to relinquish control of closed loop. Cheaper and easier than the Haltech though. Just has less capability.

 

Doesn't it say MAP when hooked too the scan Guage 2? I could have sworn it did. I also heard rumors the stock electronics could handle 7 psi. Is that true or is that bullshit?

 

Heard the same

 

Mine does too on torque pro, but that is just a calculated value to make you think you have a map sensor.

 

It has a MAF sensor. 100%.

My friend is running 11psi URD S/C', with a MAP-ECU3 , and upgraded 5th injector.

 

Can someone link me to the whole extra injector idea, cause I don't get it. And also, isn't a super charger awful on fuel mileage?

 

It's all awful on gas mileage if you squeeze the Go button hard enough

 

His 2TR does quite well. He's getting around 400 miles on a tank. In tuning and driving style.

URD may have a 5th injector kit on their website. www.urdusa.com

 

So again...

Is upgrading the fuel pump worth while having only all-motor upgrades? With plans to turbo at a later date?
If so, which one?

 

not really. id only do it if you need one.

 

You’ll need it for turbo but unless you’re doing legit head and valve work on your motor no intake/exhaust upgrades would warrant a bigger fuel pump.
