ZONES89RS

iTrader: (2)

Well, since you have done the swap before, it should go really smooth, i canot wait to turbo my 5.3 i just dropped in the 86 TA, but that will be 2000$ or so later, LOL.

good luck with your swap. definitely no need to rush, I think a few of us are taking our time with things; the best deals come when you're not in a hurry!

INTIMIDATOR Z

iTrader: (4)

think im goin to sell the one motor to pay for some swap parts or i was hoping to try and trade it for a 4l60e.

INTIMIDATOR Z

iTrader: (4)

looks like one of my buddies is goin to buy the other motor for $250. got another buddy who has a working 4l60e from a truck that he'll sell me for $100.

tryin to think what else to get. mounts, intake, waterpump (might modify a turck one), harness (so i can start setting it up)?

1ADan

iTrader: (4)

intake - go ls6 if you're using the heads you have now. unless its free (as mine was), the ls1 intake's not worth paying for just to change down the road again

mounts - i opted for the standard sbc poly mounts and the 1" set back adapters, but I'm not planning on running A/C. if you are, go the spohn/hawks/etc style mounts

INTIMIDATOR Z

iTrader: (4)

i still havent made up my mind if im goin to do a/c. ive never really had a car that had a/c so im used to it. so i might just ditch it. do you mind showin me which mounts you used?

INTIMIDATOR Z

iTrader: (4)

would this oil pan fit?

dimensions of that one:


dimensions of f-body pan:

1ADan

iTrader: (4)

I used non-setbacks when I put in the 5.3L, but didn't like how close it put the oil pan to the factory kmember. Pocket and I compared measurements (he has the spohn conversions I believe) and they put the motor back 1" closer to the firewall and open up some more breathing room around the kmember. This is what's going to be used when I move the 6.0L into place in the next couple weeks:

INTIMIDATOR Z

iTrader: (4)

alright i just happened to have those saved in my watch list. so id have to buy LS clamshells? would i have to get the other frame mounts? what did you do about fuel lines? also which fuel rail did you use? sorry if im bugging ive been reading different threads and gettin different ideas.

im goin to be keeping the stock tank just upgrading the fuel pump and adding the vette filter.

INTIMIDATOR Z

iTrader: (4)

i was looking at these which i guess bolt to the factory mounts?
http://cgi.ebay.com/ebaymotors/ws/eB...#ht_1476wt_939

1ADan

iTrader: (4)

no ls1 clamshells - these use your factory third gen v8 mounts & clamshells. I replaced the rubber inserts on the frame side with poly, but its a recommendation, not a requirement.

fuel is being done via 6an line. My car was carbed from the factory, so it made more sense to replace everything this way then to buy new factory FI lines. Using the vette filter/reg as well. Factory fuel rails with an adapter

INTIMIDATOR Z

iTrader: (4)

something like this?

1ADan

iTrader: (4)

sorta. russell makes a quick fit adapter that clips right onto the rails like factory and has a 6an thread on the other side. then i have a single 6an line going to the rear of the vehicle to the fuel filter. pocket's got a great diagram for fuel fitting part numbers around here (repost for ease of use):

INTIMIDATOR Z

iTrader: (4)

alright. i cant wait to get this thing in. dont get me wrong i love my tpi i just hate the chug chug sound it makes. want a smoother sounding motor.

Demon355

iTrader: (1)

You put a turbo 5.3 in an RX7? Dude...why own the 91 Z? Whenever I come into money down the road, I'm going to build an LSx FD!

INTIMIDATOR Z

iTrader: (4)

i love 3rd gens. i sold my 02 z28 to get a 3rd gen.

i did the rx7 cause all my buddies were doin datsuns and i wanted something different at the time.

INTIMIDATOR Z

iTrader: (4)

looks like im gettin rid of one of the motors either tonight or tomorrow. pickin up a 5.3l haness and ecu from a guy tomorrow if he keeps his word and holds it for me. then just gotta bother my buddy on when i can pick up his 4l60e. with that stuff ill at least have all the big things together.

1ADan

iTrader: (4)

that's the easy part, but having already done one swap before, you don't need me to tell ya that

oh, and i think it got overlooked, but stay away from the hotrod pan, as it hangs lower than the kmember by a fair amount. stick with the fbody pan for piece of mind, especially if you go to lower the car at all

INTIMIDATOR Z

iTrader: (4)

yeah lookin at the measurements it looked like itd be too low. my buddy asked me if i would be able to use it. wish i had some more extra money cause theres a guy on tech sellin all the accessories i need for pretty cheap.

think i still need:
intake
rails
injectors
throttle body
starter
f-body balancer
spark plugs
255lph fuel pump
alternator w/bracket
waterpump w/ tensioner
power steering setup
motor/trans mounts
vette regulator
coil packs
o2 sensors
gaskets
flexplate
couple sensors
oil pan setup

thats all i can think of off the top of my head.

INTIMIDATOR Z

iTrader: (4)

i gotta see what to do about the trans mount cause the 4l60e from the truck is like 2" shorter then the car. oh and i gotta fab up a torque arm mount.

White'89

iTrader: (8)

What do you mean its 2" shorter? Is the tailshaft 2" shorter or is the mount?

INTIMIDATOR Z

iTrader: (4)

well my buddy had both a truck and f-body 4l60e and we measured them next to each other. the truck is shorter then the f-body trans. dont remember if it was 2" exactly but it is shorter. the bellhousing and torque convertor are shorter on the truck trans.

INTIMIDATOR Z

iTrader: (4)

picked up the trans, harness and ecu today.

oh what fun its goin to be starting on all that wiring.

SiCkRs

iTrader: (6)

Nice so you do the wiring work yourself then?

INTIMIDATOR Z

iTrader: (4)

yeah i did it on my last one and on a c4 that i had that i swapped a LT1 into. kinda know how it works.

INTIMIDATOR Z

iTrader: (4)

and heres the trans

INTIMIDATOR Z

iTrader: (4)

well tore apart my motor yesterday. changed the cam (to a stock 02 z28 cam), checked it out, cleaned it a little and painted it.

INTIMIDATOR Z

iTrader: (4)

yay got my motor mount adapters today. man these are some heavy duty pieces.

1bdbrd

iTrader: (1)

With the mounts that move the engine back, what do you do about a transmission mount or even the tq arm? I'm liking that idea a lot honestly..

INTIMIDATOR Z

iTrader: (4)

im goin to pull the tailshaft off my 700r4 and put it on the 4l60e. with the truck 4l60e its actually about an inch shorter then the f-body 4l60e so it should fit into the stock trans mount pretty good. im not goin to be runnin a crazy exhaust right now so no need to buy a trans member.

bigals87z28

Ahh...the 700's tail shaft is a 4 bolt, the 4L60E should be a 6 bolt. Just putting that out there.

edit: ahh, looks like you have a 4 bolt flange back there. What did that trans come out of?

Pocket

iTrader: (24)

The trans you've got is also from a 4.3L S10, the converter isnt right. You'll need the crank adapter kit for an older trans

1bdbrd

iTrader: (1)

So say a t56 wouldn't just bolt up with something like that on it then? Damn. That would have bought needed room up front if so

INTIMIDATOR Z

iTrader: (4)

i did not know that bigal and pocket. ill have to look into what i have to do. how can you tell its from a 4.3l? just curious.

lookin at pics of other 700r4's that ive worked with and i did notice the 4 bolts. dang.

1ADan

iTrader: (4)

the mounts he got will put the motor in "proper" spacing as the old sbc was; should be about the same as what the spohn ones do, so you can reuse your old drivershaft and torque arm (mount will have to be specific to the fbody 4l60e you're using). crossmember will be different, so that will have to be modded if you're using the stock piece.

ZONES89RS

iTrader: (2)

Well, i have used those adapter plates a few times now, they are great but be ready to slot the clam shell to the inside 1/8th inch on both sides usually so they will allow the engine to drop right to the mount and the bolts to slide right in.

Demon355

iTrader: (1)

Agreed as I use the aluminum adapters.

1bdbrd

iTrader: (1)

Well right now the car has a t56 and a Skulte crossmember in it which I plan to keep both. I would like to move the engine back as much as I can but I don't want to run a different transmission crossmember if I don't have to..

INTIMIDATOR Z

iTrader: (4)

started on the fun stuff today. found some plugs im unsure of and 2 that were missing the connectors. need help identifying some of these.

started with this pretty much:


half way:


all seperated:


heres the ones that i need help on (all 4):

INTIMIDATOR Z

iTrader: (4)

this is my first time completely building a harness. do you guys take all of the pins out of the red/blue plugs and then re-pin them accordingly? goin through and i got most of the stuff im not using but gettin stuck on some of these plugs. also since i have a truck harness and im goin to be mounting it inside the car i think i have to repin the injectors since the truck harness usually mounts up front. any help is greatly appreciated.

Pocket

iTrader: (24)

I strip all the PCM pins and build the harness to suit any car. You're going to have a rough time keeping it together because stock location on the truck was front battery tray on the drivers side, Stock 3rd gen is pass rear. Ample length, just have to reorient it all. Drivers coils/injectors and sensors wont have enough length without coiling up the pass side into a big wad

The busted connector with 5 wires is the truck MAF. If you source a replacement, you can actually snap it right on there without any splicing from the connector design

iTrader: (14)

Adapters made from 5/16" plate instead of 3/8" plate help.

INTIMIDATOR Z

iTrader: (4)

alright so it looks like i have to take all the pins out and pretty much lengthen/shorten them according to where they need to go. looks like i might need to get an engine stand at least.

on another note decided to sell this trans and just try and get a 4l60e from a f-body.
