August 5, 200817 yr Ah, what a difference :-p And I think I might have found my low idle stumble/vac leak. When I was loosening the TB bolts, I found one on the bottom that was loose. I got.......creative with using the RX throttle cable. It will do for the moment. Some of the IC I have will also make do on the 90 coming from the turbo. Unfortunately, the rear bearing I was going to replace will have to wait till Thurs when the correct part comes in
August 7, 200817 yr Ok, back on topic. I should have the RX road worthy Fri. I still need the seal, the Dealer will have it tomorrow. I would have it done tomorrow, but I have a unpleasant task to attend to. Our Fire Chief's Service is tomorrow and its going to be a all day thing. For you locals, watch the 6pm news, it will be noted. Well, it was sort of on topic
August 12, 200817 yr Ok, still have a real bad low idle. It seems like a vacuum leak, but its impossible to locate. It seems to run better once its warmed up tho. When I put the intake on I didnt get the heater tube that has the fitting for heating the TB. How important is that? I dont think it would cause it to run like crap at idle.

This happened to me about a month ago with a vacuum leak. Everytime I was at a stoplight or whatnot, the engine would putter and almost die if I didn't rev it. I found the leak. It was an unhooked vacuum line the day after I put my turbo and intake back on. As soon as I plugged that up, it ran and idled fine.
August 18, 200817 yr Author Brief update , I now have a Rex TD04L-13T-6 but am holding out for a rare TD04HL-15T which was native to a JDM EJ205 . Basically it has the HL rather than the L version of Mitsubishis TD04 turbine which is a little larger and in a similar looking Subie type 6cm turbine housing . If I can get the turbine housing I can build a hybrid "TD04HL-13T-6" using the HL turbine and housing on an otherwise normal Rex TD04 turbo . Also should have a Liberty RS (Leg RS) up pipe soon and the spider plenum has been adapted to take an L Series MPFI throttlebody . Progress is slow but that's life , cheers A .
August 18, 200817 yr Mine just made a 400mi trip and got about 30mpg. And it ran like crap! I have vac leaks all over. The TB gasket was bad, I replaced it. I still have leaks :-\ I'm going to take it off and really check it out, it may have gotten warped. The non-turbo spider I have looks like it might be a better choice anyways, it has less junk on it and the wiring harness looks to be a better match to my RX.
August 18, 200817 yr The non-turbo spider I have looks like it might be a better choice anyways, it has less junk on it and the wiring harness looks to be a better match to my RX. thats the reason i went with the n/A spyder manifold/
August 20, 200817 yr Ok, I pulled the intake of the risers today and the gaskets were trashed. I had some spares and got it back together soon after. It runs like it did before the swap Better throttle response and hits redline fast Now I just need to figure out a few of the vac lines for the heater, diff lock, etc
August 24, 200817 yr Well, I tried some more boost the other day. Kicked it up to 14lbs and got no predet. But I did get fuel cut Probably a good thing tho I think this is where I stop. I cant afford to put more money into the engine side. It needs paint and some other things I want to do. Its still quick and fun to drive and reliable. But I have other projects to get to. I'll get a dyno run done in the next few months to see what its actually putting out. I had 100whp before all the mods.
August 29, 200817 yr I have 280ZXT injectors but I thought about crushing the FPR, should have similar effect and of course it's free. We'll see how it goes when I put my TD04 on, just waiting on the downpipe!
September 13, 200916 yr Author In this first pic I noticed a fuel rail conversion for O Ring style injectors on a Spider inlet manifold . Would it be possible to see closer pics of how those rails are held down ? Cheers Adrain in Oz . Rotate the throttle body. Man, this seems like such old news! Here's some pics of how I did mine. Basically what you are looking at there is a rotated throttle body, and a samco y-pipe for a WRX, cut with a pipe in the middle for added length. Ultimate got the same Y-pipe treatment too. I never was 100% sure my TPS worked correctly, or if my problem was all in the cams. I also found on ebay a RUBBER (not fancy silicone) elbow that worked for the turbo to MAF intake. I believe it was made by APEXi for custom cold air intake setups. I believe it was like 60mm or something like that. It was a good tight radius.
