Default Questions for those who have done the RS->WRX engine swap...

Hey there and congrats on the successful swap guys!

Anyway, did any of you do any engine mods such as the Vishnu Stage 1 or new turbo, etc?

Did you use the stock clutch or go with aftermarket? What fuel pump did you use? Did any of you swap the rear diff or transmission?

What was the process with emissions? Will your insurance go up becasue of the higher HP engine? Did you have to inform insurance about it?

Any difficulties on the install? Any parts that you wish you would have had or would recommend picking up up to make the install smoother?

Arnie,

I suggest you get hold of the folks at I-Speed. They are the official contact for the RS-WRX conversion. They can answer all of your questions on the swap.

But I suppose I can answer some questions.

No extra engine mods on my car, well except maybe getting my intake manafold powder-coated red. Other then that, nothing for now. I'm just happy to get my car rolling again, but I'm sure I won't be happy for long, and will want to upgrade (you can Never be just satisfied)

Clutch/Flywheel - All three conversions are using aftermarket clutch's and flywheel. For me I am using a ACT/JUN setup and couldn't be happier. The car revs with ease.

Tranny/Diffs - You DO NOT need to change anything. I am using the stock RS transmission (I know many who read this just cringed) But we beleive that the RS unit is just as strong as the WRX unit, plus it is MUCH CHEAPER to replace if I happen to break it. If you want to change the tranny anyway, give Chris or Bill a call and they would be more then happy to help you. Your choice.

You must use a upgraded fuelpump as the stock RS unit does not flow enough fuel when the engine is under boost and WILL cause it to run lean........and as anyone knows YOU DO NOT WANT THAT. Talk to the guys and they can see what application is best for you.

Yes I contacted my insurance agent on this (State Farm) and he said that my insurance WILL NOT increase due to the swap. He said that they only rate insurance on the "original" stats of the car, BUT will cover any loss of the new engine if the worst happens. SO basically I get to have a WRX, without having to pay the insurance that everyone who has a 2002 WRX has to pay.....Cool Huh?

As for any questions on the installation, I must refer you to Chris/Bill/Adam of "I-SPEED". Thanks

Cheers

EddyL.

thanks Eddy! I have been in contact with Chris to get the other details on installation but I wanted to see how the customer end is working out with the day to day reality of having the swap. Bill and Chris are great and I'm definitely saving my pennies for the swap.

Anyone else?

Call Steve at Barsotti Auto Care. He did the switch for me and I'm very happy with the outcome. I just got done auto-x in Stockton and the car is so much fun to drive.
Now all I need is a camber kit and some V700's!

Yeah right... LIAR Somehow I doubt it will stop after camber plates and V700s. Hell, with this group cars may as well have sails.

I saw one of the EJ20 conversions that Bill and Chris did. A fantastic looking job.

95 impreza L putting a EJ20 twin turbo in, anyone done the EJ20 twin turbo swap? i read you gotta cut the firewall to fit it in, is this correct or wrong?? does anyone know if the EJ20 twin turbo engine uses which tranny? can i use a 2.5rs tranny? or best if i get a wrx tranny? how much would that cost me? any quotes? i'm ready to do the swap, but before i start i wanna do all my research, sorry if i'm asking newbie question, but i'm new at this subaru stuff, i just know my hondas, and toyotas, not subaru yet.., i was wondering can i use the USDM wrx ECU? or what ecu does it use? just incase the engine i'm getting doesnt come with a ecu, i just emailed the guy to see what the engine he's selling includes, he hasnt gotten back to me yet, so i just wanna ask ahead of time..

which swap would definitely be easier? EJ20 turbo or EJ20 twin turbo?

question: what is this crossmember i keep hearing? sorry if it's a stupid question, dont know anything about subaru engine, cuz i read in these forums you gotta change it to be able to swap in the EJ20..

about the 95 impreza L i'm buying, it really cheap 1 grand maybe a lil more that's it, body is in ok condition, no major rust, so i'm just gonna swap right away when i get it, the suspensions are dead, so i'm gonna have to fix that, will the stock impreza L suspension be able to handle the motor? if not i gotta upgrade to wrx suspension? that's about it.. anything would be helpful guys thanks a lot

the EJ20TT you are getting is probably off the Legacy B4. you will have hell of a time trying to get this fit into your engine bay.

I think the single turbo EJ20 will be easier, and the best way of doing it is to get a front clip of JDM GC8 wrx.

How long did it take?
How much did it cost?
Where did you get your motor?
Any unforseen problems with the swap?

One big question: Who removed the motor from the wrecked WRX and what did it entail?

Thank you

gee so many question and so little unpaid time For those of you who do not know, i am a consultant by trade so I am used to billable time, lol.

I couldn't possible answer and twin turbo questions because I have not done any research on it...yet. My opinion is that it would be a tight fit.

here are some questions I can answer:
How long did it take?
~40 hours
How much did it cost?
it depends on what parts you get and/or want. plan on spending between 6.5-8.5k
where did you get the motor?
From a salvage yard
Any unforseen problems with the swap?
a few. make sure that the motor is operational prior to purchasing it. Make sure it isn't throwing cels either
Who removed the motor?
the salvage yard. it took a lot of time and heavy machinery for some rolled smashed cars to be relieved of their engines.
If you ever saw some of these cars, you'd not believe tht the motor would survive....but it does!

chris,

As I understand it, the wiring is the biggest pain. Is there anything a potential customer/installer can do to help/speed up this step? For example, labeling all wiring/connections on the donor harness as well as on their car. Would this help speed up the process and take away some of the guess work?

Do you guys have access to a wiring diagram for the WRX or was it just the process of tracing wires to their source?

There is no guess work involved. We have all the manuals for the impreza from 1995 to 2002. We pretty much follow the diagrams. Sounds easy huh? hahaha, some wires keep asking you to refer to different books...those bastards!
We have noticed that each car's wiring is a tad different. We trace back the wires to ensure that everything is ok and there are no surprises.
Even if someone gave us a car that had lables on the wires, i would still check and double check. When doing a job like this under the i-speed name, I need to make sure that everything is %100 ok. The only way to know this for sure, is to do it myself. I am certain that if it waas your car, you would want us to check it...right?

Sure the labels help....that's what we do before we start soldering.

FYI: the labeling/wiring, start to finish, takes about 17 hours
start to finish

17 hours! Wow, but I can certainly believe that. Hey, but with more installs you'll only get faster! But it probably won't save us any money off the install costs because you can up your labor charge since we will be paying for a more experienced mechanic! ;-) Does any of the stock wiring stay put? Or are the "only" wires you change out the ECU to engine ones? I haven't looked to see where everything goes from the ECU but does it also control secondary functions like taillights and headlights?

wow arnie.. you have a lot of questions! but that isn't a bad thing

you should trust Chris and I-Speed by now since they have done numerous installs and swaps.. so if i didn't trust them, i wouldn't have let them do the conversion for me.

My car is still running great at this time.

3200miles, no problem so far.

Arnie - It is just a time consuming task..doing the wiring. At this point there really is no way to make it go faster. I realize that some people think that 17 hours is a lot, but they have no idea what we do in 17 hours. I am talking about everything from cracking open the books, labeling all the wires, pulling out the dash, pulling out the existing wires, seperating them from the ones I need vs, don't need, soldering all of them, and using a heatgun and shrink wrap to ensure that they are securly fastened, then double checking to see if everything is correct...THEN putting the dash back together. Does that Sound like a quick job???

RimRockaz - My questions have nothing to do with not trusting Bill and Chris. I've seen their work and they have done work to my car at a couple of Sat. installs, so I know they are 100% reputable as well as being all around good guys.

I'm asking as a curious guy wanting to get a better idea of what is really involved in doing the swap since I wasn't able to attend any of the last few swap installs. I've never done an engine swap and the process of doing it fascinates me. Of course, I'm also saving my milk money to have Bill and Chris do the swap, but I'm not content in just handing over the keys and saying, "go to it boy's". I like to learn as much as I can about my car and I'm sure these questions help other's as well. I'm not trying to find ammo to throw at the boy's to lower their costs. They are probably by far the least expensive out there as far as install costs, but well worth every dollar.

Chris - from your description I can imagine how/why its so time consuming. I had visions of it being "somewhat" easier. More along the lines of just yanking the pertinent RS wiring out and plugging the WRX wiring in. Had no idea that there would be so much "slicing and dicing" involved. Thanks a lot for shedding more light on the complexities of the installs. Till now most engine swaps have been simply reported as "its in and it was tough but my mechanic got it done!" Very few have given us the behind the scenes nightmares that await.

quite frankly, thats all i could say "its in and it was tough but my mechanics got it done" when they finished my conversion, because i did not participate the engien swap. if it was about Mazda RX7 FC3 13B engine swap, i can shed some lights..

plus, I promised Chris not to shed any info that i know like the final cost and such..

Hey RimRocKaz, no offense taken! I may have come accross as nit picky or something when I asked my questions. As far as the end costs, I would only speak to Chris directly and offline. I completely understand discretion, esp. since every case is different. Hell, this is something (dropping in the EJ20) so many of us have dreamed about since getting an RS and its great having a adventurous competent group of installers in our own backyard. I remember trying to figure out the costs of shipping my car out to Rallispec to have them do the swap a few years ago.

But I appreciate the ride offer, (and will take you up on that!) as well as all the insights people have provided thus far.
