Arrow Finalizing the EJ18 turbo project...

Alrighty, ive got just about everything I need for my EJ18 turbo project sans a few details. Heres what I have so far:

WRX Turbo (TD04)
Apex-i S-AFC
Vortech RRFPR (with an unknown ratio)
Apex-i ITC
Greddy EGT Gauge w/ probe
WRX turboback
VDO boost gauge
WRX fuel pump

As of right now, im still working with these EJ20 heads that I got to see if they will actually work with the EJ18 block and how much actuall work it will take to get them to work. Since I have no idea if they will work or not yet, I guess we can just ignore that for this post. (If they do work, I plan on using WRX injectors/fuel rails and probably a WRX intake manifold, or maybe an RS intake manifold, but the rest of this kit will apply to it)

I do plan on running Legacy Turbo fuel rails/injectors with the kit, as well as the stock exhaust headers with a custom uppipe (possibly subachads uppipe) and have the stock wrx downpipe modified to work with that uppipe (or perhaps the other way around if I just have a custom uppipe made, but a suggestion on which of these two ways to go would be apreciated).

I have not decided on a specific intercooler yet, but I do have two options right now: A legacy turbo Air-Water intercooler or a FMIC using a GC8 designed core that I can get. I havent made up my mind yet due to the WRX heads. I can probably use the heads to get the air-water setup for cheap, but the GC8 core I am getting for free but the piping will surely be expensive. So really its a cost issue for the Intercooler, and it will depend on which way will cost less, but I like the idea of the Air-water intercooler because it looks totally stock. (TMIC is out of the question, I dont want to do a hood conversion)

As for the intake, I will use the stock airbox probably with the MAF adapter I already have along with some piping I already have as well, so thats not an issue.

However, I guess I need to know what else I need to do, like what extra piping, wiring, etc. I will need to complete this.

But I guess my biggest question is whether my management setup is overkill or underkill, and what I need to do with the RRFPR and I do plan on running somewhere around 6-10psi since scubydrew's setup is comparable to what I will be running http://forums.nasioc.com/forums/show...488&perpage=30

Anyway, any and all info will be usefull

i have a wrx tmic with samco hoses available if you change your mind... i was gonna turbo my 2.5, but i need to keep the car as reliable as possible seeing as i wouldnt have the money to fix it if something major broke.

i wasnt gonna do the hood conversion either, but rather graft a scoop onto the stock one and cut a hole in it. im sure there are a couple other options for getting air to flow through the tmic too... anyways, i wish you the best of luck with this. i'll be looking foward to the results

I'll trade you the ej22t manifold, injectors and rails for the GC8 FMIC core you can get for free. Let me know.

Good update on the turbo project, sounds like it's finally coming together. I gave you a ride in my car a while ago and it's much stronger now that the RRFPRR and new set of exhaust pipes. Too bad the engine went boom...

Have you installed anything yet? Like the AFC or ITC?

Oh and hi Josh. Yes I'm still on the forums I'm not living in Tigard any more, I'm actually in SOCAL now. Not sure how long I'll be down here. Just making the best of things.

a kostamojen what clip does your ecu have. if it's blue and has 2 seperate sides it's the same as mine. if not i believe it'll be green with 3 parts. anyways if you find out you have the same plug i'll send you the itc pinout i used. btw there's a feature on the itc where if the dipswitch is on you can only go plus or minus 5 degrees. the guy who sent me the directions told me to have this on but when i tried that my car did not start. after turning it off it started fine. drew

Let me know on that IC I have a little welder that I can use to make the piping. Let me know if you need any other parts off the ej22t longblock too.

Yeah dude, no problem. No hurry. I wont be able to put my engine back in for a few more weeks anyway. I might be selling my polished TMIC if I get that one from you. Let me know if you know anyone who might be interested. It's a dual core SPearco unit.

Question: What about using a TD05 from a JDM engine for this kit? And how about using one of the little oil boxes for the kit from that same engine? And has anyone tried the modified stock injector thing with the EJ18 injectors yet?

so are you looking to go with FMIC if you use the GC core? a ittle confused with the piping cost being high. Sounds like you still have a little decision making left but sounds like you have a sweet car once it's done.
Take it easy, Micah

what boost levels are you planning on running in the long run? are you going with lower compression or whatever will work with the WRX heads?

Whatever boost i can run... Im thinking around 10psi with the ITC, might run lower. I dont plan on running the WRX heads right now, im going to build that EJ20G instead and put it in whenever I can (several months from now)

Naw, still havent installed it. Although it looks like i need to do it myself, as its going to cost too much to have it installed. I think I need to do the boost gauge, EGT and ITC myself as well.

You should be ok. The AFC is not hard... Did you figure out if you have the right ECU pinout for your car yet? (from apex'i's site?) I'm looking at doing my EGT and oil pressure gauges this weekend. I'm just going to follow the scoobymods instructions that tmat wrote and everything should be cool. The boost gauge taps into one of the tubes that will be installed with the rest of the kit, so that one will wait.

That explains a lot. I was confused about why you were doing this when you have those pretty pics of your new block and TD05 over in conversions...
I am gonna do the similar sort of thing with my Legacy.But, I am gonna drop an EJ20 into it and sell the car to pay for the build of the EJ22-T, before I slip that into a GF Impreza...

Considering that most of what I do for the kit will wind up with the EJ20, it makes sense to just go ahead and do it now too.

Ok, looks like im going with a legacy turbo crossmember and the headers/uppipe i have from the EJ20G. I also have the water pump from it, i hope its compatible... Any tips for this?

Oh, and will a TD05-16G be too big for the EJ18 kit? Its going to work better in terms of placement than the TD04 (cause of the air inlet) but its going to spool much later...
