Will you build and tune it yourself or do you need to pay for labour?

What's the budget for building it up to 500whp?

Does the car have to stay auto? If so, you might be looking at a ZF swap in future.

For a visual -

They also make them with the motor mounted on the side

Nice, let me know how you find the 98 tune

The suspense is killing me lol. Are you going to buy a flex sensor, then add the 98 tune to your current tune? It sounds like your just going to delete the current tune and re-tune the car on 98 =/ If you've only known your car on e85, I don't think it will be long before you install the flex sensor and go back to running e85 when its available lol.

This is very confusing. "flex setup" = being able to run 98, e85 or any % of ethanol. If your tune only supports 98, that is not a "flex setup". I don't understand your hesitancy for running ethanol. It's just better. It makes more power and is safer. What's not to love? Also it smell amazing lol.

But if you've got the flex sensor whats the issue? You just run what you can get your hands on. I can't see any reason not to run e85 if it's relatively local to where you live.

Any damage to the box/input shaft?

Quick update. The engine grounding strap was replaced, the engine is now happily running. Tested the voltage drop before replacing the strap, was about 1.2ish volts down between engine to battery, chassis to battery. With the new grounding strap, pretty much no voltage drop at all.

Do you mean not a limit to a certain power level? Surely if an injector is 100% open, there will be a limit to how much fuel can flow through it.

So you want to run e30 on stock injectors and fuel pump?

What extra parts are you thinking you'll need to run e85 compared to e30?

Would this not be the same for the exhaust you've posted up? If your exhaust volume and emissions are fine, why does the brand of pipe matter?

First thought, have your current injectors flow tested. If they test fine, keep the diagnostics going. It's not the injectors. If the injectors are the issue, find some new or used (cleaned and flow tested) injectors. While I really love a good excuse to get a modern ECU installed, just needing new injectors probably isn't a good enough reason to do so.

@sunsetR33 There is obviously a huge culture gap here. There is nothing in place like this in Australia, where if you fit a Mines branded pipe and later replace it with a Jun branded pipe, both pipes are essentially identical - BAM - huge penalties! Where is the Mines pipe?? You can't have a Jun pipe when you said you had a Mines pipe! Makes no sense to me. Surely makes no sense to anyone else here either. I'm sure a lot of us would agree that our registration/engineering system is pretty stupid at times, but it's not that stupid. *** More serious question here. If you replace a factory rubber hose with a silicone hose, is the car illegally on the road now? Does it become legal if you have certification of what brand the silicone hose is? Then would it become illegal again if you replaced that silicone hose with a difference brand of silicone hose? And then would it become legal again if you had certification of the new brand of silicone hose? I really want to know that answer to that question.

Is this a trivia question or is there an issue you'd like help with?

We are talking about different things, all I'm saying is there are plenty of people out there that don't stop modifying their car after it has been engineered.

I'd say the most common scenario is the car's build has 2 stages, all work that can be engineered is done first. The car is passed then the second round of mods start, all the ones that can't be engineered lol.

Things change over time but all that matters though is that the vehicle is compliant with the rules that were in place for the year when it was constructed. Go back far enough, cars didn't have seatbelts or catalytic converters. You can still legally drive them without a seatbelt or cat fitted. It's not like vehicles need to be updated every year to match the updated ADR's to stay road legal.

I do

You've just discovered a really good reason to tell yourself, yes, I do need to buy an aftermarket ECU. Put the MAF in the bin. Slap in the new ECU and have a think about what turbo sounds you prefer. Do you want a 90's style BOV wooosh? Do you want a hektik tsututututu? Mate, can't go wrong. Just gotta get that ECU and the world is your oyster.

Maybe something like this - Plus this -

As GTS mentioned, it takes a bit of faffing, some fiddling and a little modifying. With the strainers, you can buy different styles. Some sit flat on the pump, some angle down. Here are some photos of mine, ignore the ugly welds lol.
