Default Question about swap.

So i'm doing a swap soon of a 93 EJ20G in my RS

I got alot of question concerning the swap.

1.So for the wiring do i have to rewire the whole car? like changing all the fuse box and all these things?
2.Where to get replacement hose?
3.Can i just buy a straight inlet turbo then buy a 90 sillicone inlet?
4.Do i need to replace my radiator for a slimer one in aloy? (Like the cxracing one)
5.I'm going FMIC, I've read somewhere that we need to relocate the coolant tank?
6.For CAI, what are my option?
7.And i'm thinking about trying the ESL live map thing? does anyone already tried that?

1. the majority of the car has to be wired and extended when merging the harness.
2. ECS sells and merges harnesses
3.you can do the straight inlet turbo, a few guys on here have a VF series and whatnot with a 90 degree tight radius coupler.
4.you can use your stock radiator, it is 100% fine
5.the coolant tank does have to be relocated, bc the charge pipe goes right down where it used to sit, right beside the radiator fans and the timing belt cover on the drivers side.
6.for the ej20g, apexi makes a kit designed for this motor, and for the 90 degree inlet on the turbo, comes with everything.
7.ESL?? never heard of it,b ut from the sound of it, kinda sounds like the maps are down loadable, kinda like chrome on turbo hondas, i would try to stay with something alot more users have and give good feedback on.

It tastes like burning

1) There are ways to do the wiring were you do not need to extend any of the harness and you don't need to redo the entire RS wiring. I have done the wiring prep for a few members here if you want to consider sending it out.
2) What kind of hoses? There are Samco kits for nearly all of the coolant hoses.
4) I wouldn't recommend the stock radiator just out of principle.
7) The "Live Map" name is a misnomer. They only allow remapping capability to vendors in the UK, not to individual users. I can help with a chip upgrade for more boost and a better tune if that's all you are after.

you need the heater hoses that were cut, you cna use your stock rs ones. as for radiator hoses, you can pretyt much go to the auto parts store and just pick the ones that bends the right way bro.

Just look at pictures of other people's FMIC kits to get an idea of what to do. It's not hard at all.

If you want OEM, there is an inside-the-driver's-fender-tank that came on older model wrx's. I got lucky in finding mine. Autozone also sells a tank and hoses that will relocate it but this is only marginally better than a soda bottle.

i have done a EJ20K in my 97 legacy and as far as wirring gors it was time consuming but easy. I modified the stock engine harness to fit the engines sensors and then I cut the harness at the ECU and soldered the wires to the EJ20K ECU plugs.

do you have the entire wire harness/ECU with your motor?

when I did an S14 SR20DET into an S13 I used the entire S14 harness and the only modifications I had to make were wiring the Tach, CEL, and some other dash warning lights and the power relay to the ECU. it was like 8 wires total. Saved myself a lot of hassle doing it that way instead of trying to mate two different harnesses.

accessories (lights, starter, ignition) are separate from the motor so you shouldn't worry about that junk.

And piping/FMIC, that's where you get to show your creative side

if you can't find a stock canister just make one or take one from any random car as long as it fits in your bumper or wherever you want to put it you're groovin.

or, even better, haha, run your charge pipe through it, then you'll have FMIC and water cooled
