Default Turboing 1zz questions

Hey guys so, tired of the the celica Being so slow, so soon I wanna go turbo. I have a couple questions like how much will I be be spending for a decent turbo, and what engine mods do I have to do to go turbo? I heard we don't have to rebuild our 1zz's but I have no idea if that's true. Thank you

still not low enough /:

For 6-8 psi a rebuild is not needed. As for how much you're spending that depends if you have an auto or a manual. You are looking at at least $4,000.

I honk at other Celicas on the road.

Without building the engine and running 8 psi you push aprox 180-190 to the flywheel.

It's about a 40 hp or so increase. Increase in torque is around 12 ftlbs according to monkeywrench racing.

Thinking if it's even worth it

This is why most people go with the engine swap first and build the 2zz. Like Fox said, just to get your 1zz pushing about the same power as a stock 2zz, you would invest approximately 3000-6000 depending on turbo, if you do the labor, and tuning. Don't get me wrong. It's totally possible to build a 1zz. You just need $$$ and patience.

Very few people have swapped then turboed. They Swap and super charge.

The 1zz has more torque then a 2zz. A turboed 1zz can be built to withstand more power then the 2zz going turbo to turbo. It's significantly cheaper to turbo a 1zz then a 2zz.

I didn't say turbo, I said "build". I know 2zz engines are boosted sometimes. Personally I am building my 1zz(I'm hording all the parts I need). My point was that if OP's goal is just around 200whp out of a GT, it's better to swap the engine. Now my goal for my 1zz(about 300-350whp), will require lots of internal mods.

Again a stock 1zz has more torque then a stock 2zz. It is a better idea to turbo a 1zz then to get a 2zz. In reality, unless you supercharge or buy a Lotus 2zz, the 2zz really is not worth the upgrade. Buying a 2zz and then building it will only gain maybe to 200hp without boost. But they would be way high up in the range, to where a 1zz will be better suited as it gets its power much lower.

I think you also missed that OP has an auto which is a problem. You have to switch to a 2zz auto trans or manual transmission as the 1zz ecu controls the tranny. So spending 3k to boost his 1zz is a much smarter idea

I'm not saying you're wrong. It's just your tune(stance on the matter) is much different than what I get on NewCelica. Try posting anything supporting modding a 1zz and watch how most of the old-timer members will tear you up.

"Build" was an ambiguous word meaning FI, turbo, or supercharge. Again, I'm trying to build my 1zz auto as well. As you can tell, people like me who have faith in a 1zz got torn down with little support.
