    build 1 my 88 mazda rx7 ls1 swap

    here is the story my rx7 has been with me for a very long time! i love this car for some reason! i just cant seem to give it up! I had a 13b NA in it and i said well i want more power so i swapped in a 13b turbo

    so after blowing yet another seal i got sick of the motor and i was going to sell the car off. then a buddy told me put a v8 in it and call it a day. I thought he was crazy but then i started searching and sure enough people started swapping v8s in them! so i picked up an LT1 from a junk yard



    after the machine shop got it it was bored out 30 over.

    new pistons

    all together well the short block



    now don't laugh but at the time all i had was this bright blue paint..lol


    all together


    intake after a nice hot tanking and paint



    flywheel resurfaced



    all together now

    mount kit installed

    motor fit in pretty good and i was shocked to see the shifter in the stock location



    after a few more weeks i finally got it running


    then i bought a house and had some time and space to work on the car
    now don't laugh to hard at my wife no clue why she thought the camera was not picking up audio!

    lol

    yes those are mustang wheels

    i had some issue with it and it was electrical! and boy did it bother me but i finally got it working again man i miss having a cammed motor..lol

    and my first time auto crossing

    then i started having electrical issues again and i ended up like this

    yup you guessed it opti spark again! then i said ok thats it i am tired of this time to get an lq4. so i got my LQ4 home and then a buddy came over and said to me "hey what are you doing with that motor?" told him its going in the 7 and then i he told me something i will never forget! "lets trade block for block" you cant even imagine the smile i had on my face i was like hell yeah!
    so i got it home and this is what i had!

    inside the vally

    inside the valve cover

    with the ls1 intake back on it!

    ported ls1 TB (thanks jamie)

    fuel rails and lq4 turck coils on it


    maf and water pump bolted on

    ls1 flywheel bolted on with arp flywheel bolts and apr pressure plate bolts


    the things not on yet!
    f body crank pulley, because i don't have a puller for it yet

    f body altenator, because i don't have the mounting bolts yet


    and the wiring harness and pcm in the box not ready to start modding it yet..lol

    playing with the slave cylinder to make sure that i can use my setup


    i took the stock quick release from gm so i can use my SS line from the lt1


    happy to see that it fits well and i am going to buy a new fitting so is 180 not 90 degrees


    thats all i can do for now until i get some parts solds so i can buy more parts to finish off the swap!

    Some stuff done today!
    ran my fuel lines today! and put in my vette fuel filter and ran the lines the way it needs to be. I ran it the same way Granny shows on the website


    ran the line from the master cylinder to the slave cylinder


    and installed the oil pressure sensor


    things not pictured the water temp sensor is in

    I think all that is left for me to do is the headers, get the lines from the heater core to the water pump. mine are to short so i am going to route that this week!

    ran the hose for the PCV,

    if you guys can think of anything i need to do please let me know. if not i think i am almost done. all i need is headers done, a small pipe from the headers to the exhaust, O2 sensors, starter bolts and bolt the starter to the block. wiring and ready to go!

    greg doing what he does best! wiring



    then busting a groove on the welder!

    but getting welds like this!


    Chris finally getting off his ass and doing some work!


    he did a great job on my gauge cluster! The stock rx7 cluster is a cable speedo so we took an integra speedo and wired it up to the VSS and its almost perfect! when it should of been 60mph it was reading 57 i can live with that much better then having nothing or having one that says 45 and doing 63 like my old one was!

    greg had to put all 125 pounds on it to get it in place! LOL

    still not there yet!

    you can't see the hammer but i am beating the hell out of the firewall for about 1 inch of room for the header to get in there!



    finally got it to line up right!




    now i have to figure out what i am going to do with the pcm



    finishing touches before we start it up



    and finally this!!

    finally off jack stands and moving under is own power!!

    well i worked on it some today. i spent yesterday and today trying to find some intake piping so i can make a nice cold air intake but i couldn't find anything that was 3.5, since my MAF is 3.5 i figured i would be able to find something man was i wrong. A & A had only ricer intakes that where2.5 or 3 inches but no step downs so i could at least put the 3inch intake on. So i ended up going to home depot and went to the PCV section and i fould a 3 to 3 but when i messured the inside of it, it came back 3.5 on one side and 3 on the other side. so i took it home and used all my old LT1 stuff and came up with this



    what do you guys think?

    i am proud of myself! i actually sat there with a wiring diagram and found the illumination wire so when i flip the headlights on the gauge turns on



    now all that is left is to put the rest of my interior back together mount the pcm,wheel alignment and exhaust. I should have my interior back together this week I hope

    i got her back on all fours and started getting things together. i have so many small things to work on. but here is what i did today
    don't mind the open master cylinder i was about to bleed it but my garage is such a mess i couldn't find my bleeder..lol enjoy!
