Lotta questions you'll need to answer first though.

1. Budget
2. Power desired
3. Budget
4. Fuel system
5. Engine build
6. Budget

Etc.

You posted in the right section, but your question is too broad. Have you looked at the Sticky posts on the top? What is your budget? What are your power goals? Looks like you're a new member but at least do a little research with the search button...

EDIT: THE TECH beat me to it.

Probably 5k max
300kw or over will be fine
No clue about fuel system
Pretty much stock 13B-REW

Best bet would be a kit. Will go over the 5k budget by the time you do fuel, ecu, tune, clutch, intercooler, and all the little things that come up.

Well over 5k, my friend.
Turbo kit = $2700-$3700
Fuel system upgrade= $400-1200
Aluminum rad =$150-$300
Intercooler =$350-$900
Ems=$700- $1200
Tune$350-$600
chances of something goes wrong= priceless.
Other small stuff like bov, boost controller, new vacuum lines, block of plates, etc...
You have a good homework to do..
The numbers above are just rough idea.
Good luck

you're in NZ, call up Green Brothers or some other shop and let them do it. It will probably work out cheaper.
I dare say $10-12k minimum.

Yeah if i wanted a company to do it I would choose either green borthers or curran brothers. Both do good work. I'll probably wait til i can afford it safely if i don't end up selling mine

You could definitely swing uprating to something like the SP twins or BNRs within your price range, along with a few upgrades (ECU, secondary injectors, and IC being chief among them) to bump your power ceiling on sequential twins, without going too far over your budget. That would give you the pep characteristic of the oem twins, with the potential to meet the power of a smaller to mid-sized single. You'd just need to maintain the complexity of the sequential twin system (do yourself a favor and MAKE SURE your solenoids are properly functioning.. issues there will cause problems).

To go from fully stock to properly done single turbo in one fell swoop is pretty pricey. Your better bet would be to add half of the ancillaries while retaining the twins, then add bits here and there until the rest of the supporting mods will support the single conversion. At that point it would be easier on the wallet to swap the turbo/hot side piping and modify the mapping.


The other advantage to upgrading it piecemeal is that if one of the modifications causes an issue you'll be able to identify and isolate the culprit MUCH more easily

Definitely do fuel, EMS and intercooler first for your twins while keeping single turbo in mind.

From that point it is just bolting on a good kit and hooking everything up.

Upgrading the twins would still be pricey and going single turbo will clear alot of room where as upgrading twins there will still be a birds nest of vacuum lines and stuff so yeah

Well, you wanted advice/opinions. What you do with it is completely up to you.

You think upgrading the twin is pricey? Going single is even pricier... Then you definitely bought the wrong car for cheap reliable power. Sure going single will simplify a lot of stuff, but like the other said it prepare to spend more than 5k.

In NZ you'll find its cheaper to buy an already built single turbo car. Half the cars on trademe are single turbo. I nearly bought a 300kw rx7 for the same price I paid for my stock one!
Fix the twins and have some relatively cheap fun first ☺
