    04' GTO front mount TC78 LQ4

    Its been a long time since i posted on this forum, so i Just thought id share my latest build with everyone here. After the first round build that never got started and had to sell all my parts, and the nitrous, and the previous rearmount turbo setup, i finally got to get started on my Front Mount TC78 with a 1.15 A/R hotside Build. Round 4?? i think now, lol.

    Its been a real pain in the ass so far, no lies. I wanted to use the driver side, Not happening :bang: i now have to relocate the battery to the trunk, (needed done anyway, forced upgrade? ) and re-route a couple coolant lines, nothing i cant handle though.

    I currently have a built 4l60 with a yank 3200 stall, and now a LQ4 with ARP 2000 rod bolts and Head bolts. Should live for a little while, atleast until my AES 390ci motor is built.

    so, on with the pics. (sorry, my phone only has a 5.0 MP camera )

    turbo


    manifold on motor


    driver side exit


    bend down from driver manifold, PAIN IN ASS! i hate pie cutting, oh, the pieces that made this, are the left overs from the pieces that were supposed to make it, lmao. i guess my thinking was way backward. lol



    looking toward passenger side where turbo will be



    a look at the driver side down turn


    passenger side downturn that will go into the merge


    basic idea of where the merge will be, i may not use this piece, i may make my own to save alot of space. its probably too tall this way.


    Lots more to come, this was just today and a little last night.

    Im still a bit nervous about the alternator on the lq4 as the upper bolt on the bracket that bolts to the block next to the motor mount is not the same size, so i will need to find that bolt from a junk yard or something. just doesnít make sense. :bang:


    Well i decided to tackle my down pipe tonight, and was quite surprised with what i was able to do this time around, seems like after my attempts before then jay really helping me out the other day, i was able to get something else accomplished, im quite happy with it, turns out any kind of extended welding is not easy with a hood that doesnt dim the arc for shit!
    heres some pics, im going to be installing an electric cut out on the downpipe so that i can meet the rules for having mufflers and still be able to run wide open for mega fun :twisted:











    more to come as things progress

    Nice.....very interesting. Are you doing all the fab work yourself (welding, etc)?

    im doing all the fab work yes, i tacked everything together, yes, and did some finish welding on things that wouldnt be seen, but the downpipe was taken to a pro to be tig welded.

    We just got a spool gun for our millermatic at work, so i may even be doing my charge pipe without any couplers, except 3.

    havent decided yet.

    Yeah, that motor is going to be a prime runner for a true street class limited to an 88m turbo.

    That is the next endevour, although, not with the goat. Probably an Fbody since i cant stand mustangs, and hate just about every other car out there.

    I still think they are played out, No offense, i still like them, just wish i could find something GM body that will work and is not ugly as hell.
