I tried searching for this. I'm looking to, maybe, go MK turbo in separate stages to cut down on the upfront $ and down time.
Probably MS3 first, learn to tune some, then MK kit, and diy an intercooler last.

Before I take off the front bumper and fiddle with pipes for a month (I have little free time), I would like to get the manifold, down pipe and exhaust on and done in a weekend and practice some tuning and enjoy driving some more before the last push with intercooler and tuning for turbo / injectors.

Here's the ?, are there adaptors out there to delete a turbo? Again I would like to get the manifold, downpipe, wide band, and exhaust done first. I would think someone would make a T3 delete pipe from manifold to down pipe. I would still use the turbo to position it all, although a good delete pipe would serve a purpose there too.

Is there such a thing? I couldn't find it.
I realize just doing it all at once is simpler.
Thanks for any help.

 

I’m no expert but I think you can wire the wastage open to keep the turbo from building pressure.

 

IMO, get the ECU installed and spend 6 months fiddling with tuning. Save up your money and do it all at once. Spending money on a turbo bypass of some sort is just going to raise your overall cost.

To answer your question, I've never heard of or seen a bypass for a turbo manifold. I suppose you'd want a turbo flange that then mated up to the downpipe. You could have something manufactured I'm sure, but again it seems like an unnecessary project and expense.

If you have a kit you should be able to get it installed in a weekend, give or take a couple nights the week before or after. If you want to do prep work, I'd say get your oil pan drilled/tapped ahead of time and cap it instead of trying to install the manifold, downpipe. Exhaust could be installed early too assuming it bolts up to the current manifold.

 

I've seen it done for emissons a long time ago, where the CHRA was removed and blocked off, so exhaust still went through the manifold, turbine housing, and down pipe, and coldside intercooler pipe got a filter. But it's far from ideal, and I don't think anyone's done any long term testing of it.

Wiring the wastegate open isn't going to do anything, MKturbos over boost enough, you'll just end up with really shitty spool and still at least 5-6psi above ~6000. Here's your warning: port the wastegate hold before installing the turbo.

As you said, I would install the MS/wideband first, then injectors, tune that for quite some time, then do the entirety of the turbo install at once.

 

I installed my intercooler and pipes before turbo. You can do everything but the hotside work first.
