boosted 3rz with stock ecu

[The Witzl]

im gettin an aftermarket ecu in a few weeks

Problem solved.


Dont bother "replacing" the TPS. I have NEVER known a TPS to break, i've only known them to be broken by roughhandling...... the only problem people have with the TPS is they dont adjust it.

Out of interest, what power are you getting out of the 3RZ with the turbo, I have seen the ARE 180 with the built 3RZ and have been seriously contemplating replaceing the 3sgte with a 3rz, but havent found may people that have played with them here in Aust

[EldarO]

the ARE 180 cant be compared to anything living, that thing is mental!

I've got a 3rz ute as well, and its pumping out an easy 300rwhp at only 14psi on basically a highflowed vg30det turbo.

The ARE 180 is just mental, fully worked everything and dry sump.

Do you want it to turn or be a dyno queen? I would've assumed the 3RZ would be fairly heavy and thus make a mess of the cars balance.

Hey Guys

The 3RZ should not be any heavier than the 3SGTE already fitted into the car, I understand that the ARE 180 is off the dial, but if I was to do the conversion, we would build it to the same level as the ARE car any how, but I am simply enquiring as to if there are any inherant issues with these engines?

Are you sure on that? I would've thought it would easily be bigger than the 3S.

Surely it can't be that much heavier? The 3s-gte is no light weight.

the 3rz isnt a big lookin engine . around the same size as the 3sgte , u could easily make over 400-500hp with a forged rebuild and the usual to go with it. i know of one making 500rwhp daily driven, thats a built motor but nothing thats not usualy done to any forged engine.

It's 2.7l, and built with commercial use in mind, it's bound to be heavier. The 3S is pretty bloody light compared to something like an R-series engine, and they're smaller than a 3T!?

[BeRad]

but its still a 4 banger at the end of the day, it cant be as heavy as a nissan fj20 etc and they put them in light arse datto 1600's and still drive quiet well. i guess it all depends what you want it for, circuit racing etc it wouldnt be the best choice, but just to have some fun on the street and at the drags would be ideal in my eyes haha. massive amounts of torque for a 4cyl and then backed up with boost, cant beat it, im in love with mine and its not even running properly yet haha

If you go digging into performance forums there was a big thread on 3rz pros and cons. It's got a good following in the states and capable of big power, but it's a truck motor not a sports car engine. How it would last in a circuit/race car is a bit unknown. Apparently it's a little bit like a baby 1FZ-FE - strong as anything with huge torque/power available but not real practical for a racing car.

Hi,
Here is some 3RZ-FE pron for you guys.

i think the 3RZ is a great little motor, decent displacement, although, at 2.7 litres, and 4 cylinders, your looking at a less than ideal stroke/bore, maybe a little bit on the too-much side...

still, they're proven to make big power, but as to whether they are suitable for high revving-applications, who knows.

that said, with the right amount of design and money, anything can be done...

With a 95mm stroke they're certainly not built for revs. By comparison the 7M has a 91mm stroke and it's hardly known for its revvy nature.
