Revert to twins or go single?
Hey guys!
I recently picked up somebody else's unfinished project and am trying to come up with a game plan.
The engine bay is about halfway disassembled, no rad, IC or piping installed. The engine itself has the intake up to the throttle body and a single turbo manifold installed. I do also have the stock twins.
The question now is: Do I buy a turbo for the manifold, make up some IC piping, maybe a V-mount setup and bite the bullet on a standalone ECU all in one shot? Or is it worth it to first assemble the car in stock form and source all the missing components for a stock TT setup?
What do you guys think?

What will get it out of the garage earlier and allow you to enjoy it more?

Staying stock twins but going full send with a greddy v-mount, PFC, azeknight solenoid kit, axillary injection, 99 spec twins, pfc and 4.44 rack and pinion for the rear end. I am primarily driving on the street, and want to keep the FD as true to it's original intention as possible. If/when the 99 specs go out, will try to source another 99 spec if I can find a good deal on them or maybe one of the Hitachi ones if they're ever affordable. 7670 and 8374 are future possibilities, but would love to stay twins.
Really comes down to what you personally want. Should stick to that. For me making sure my FD is streetable, retains "drivability" and has power at the low end was important to me personally.

Some single turbos are hard to get right now, expect 3-6 months probably to get the turbo.
Post up some pictures if you can.
Getting the turbos with all their piping shouldn't be too difficult to find good used.
Do you know the health of the engine?

Wow, that is tough. It boils down to what you want after a bunch of research. You want a drag car or a good all around street car. Are the single turbo parts of good quality? Will an efr bolt right up? If you aren't interested in the fastest spooling singles on a street car I would stay with twins.
It is about $ and what you will enjoy the most.
Post some pics and give some more info in what you got.

To elaborate on what Zepticon said, if you have all the stock parts at least keep them as the car could be converted back.

what do you want to do with the car should be the main question because you can have a mint car and be single (turbo) at the same time ...
the answer will lead you to the direction you should take

Thanks for all the feedback and guidance guys! It's definitely nice to see a community be so supportive to a newcomer.
Before buying the car I borrowed a Rotary Compression Tester and the numbers came back decent but not great. I don't remember the numbers offhand but I wanna say the worst was high 70's and the best was low 90's. (Before correction).
There is also the question: Do I rebuild now for peace of mind? Or do I trust the numbers and just run it?

As far as my goals for the car:
Ultimately I'd like to be around high 300's to 400whp. I want to drive the car on the street and the occasional track day.
I do have a spare GTX3582R Gen2 from a different project (I didn't like how laggy it was on an RB). Which I could throw on the 13b. From what I've read on the Turbo Comparison chart that should be a decent fit for my power goals.
Are the stock 93 twins capable of the power goals I have?

I have a bin of misc parts including the stock intercooler and a bunch of couplers/piping. The turbos themselves are still on the manifold and seem to be a complete assembly. I also have intakes for them. It would seem that the twin setup is at least 75% there but it would be on me to make heads or tails of the mess.

Be sure you have all the solenoid and vacuum piping, if not you'll need to source them. Not sure if you mention if this is a LHD or RHD, but did the engine harness get touch?
Lay everything out on a spreadsheet with cost and availability, it will help you make the decision logistically and financially.
