Re: My 1989 IROC LS1/4L60E swap
Can anyone help me with a good pic of the area that needs to be cut out for the 4th gen coolant tank mod. I have been looking for some time and cant seem to find one. I dont want to mount it under the tray as some have done but I have seen it done two ways from above. I dont want to cut the side support, only batt tray? From what I have seen this will put the tray on top of the frain rail by an inch or so.

Re: My 1989 IROC LS1/4L60E swap
Potentially there are other R4 compressors that will work and have the ports clocked differently so the lines wouldn't be against the inner fender. My friend ordered an R4 compressor from Advance or something and wound up getting two, one was for his truck and he isn't sure about the other. I am going to see what the second one he got was and check to see if it clocks the ports different.
I downloaded the instructions from Holley before I bought the brackets, so I knew what I was getting into before I purchased. IMO the brackets are nice, but by the time you are done buying all the parts necessary the pricing comes close to buying a GM C5/C6 serp setup which comes with a new alternator and compressor. The only reason I bought this setup was that I wanted to use the stock R4 compressor for this build since I already had it and I had an f-body water pump so it was less parts to buy since I already had a truck accessory setup.

Yes, Stock V8 manifold assembly. Never even cracked the system open. Would be cool to find an R4 with manifold outlets clocked in a better position. With the Hi Pressure switch there it wont allow any re-clocking.

Re: My 1989 IROC LS1/4L60E swap
Thanks! Starting to realize the lack of room around the transmission when it is installed. DAMN! Gonna have to hook up lines and electronics as well as o2s before the trans goes in the hole!!
I need some help guys. 1. My doner alternator has the big red wire that goes to the Batt. and on the plug there is only one little red wire, Where does it go??
2. the tan wire from the Oil sending unit. where does it go?
I see the draw back (one of them) using the factory 89 K-member. You really cant tilt the engine back enough to easily get the bell bolts in during trans. instal.

This wire here, plugs into the alt. and goes? It does not go to the computer that I know of.

Alt wire goes to the PCM R15 for 99+ PCMs
For 98 PCMs is gets 12v IGN through a 470ohm resistor

Another for ya, on the 89, the stock fuel pump relay has two wires I'm not sure what to do with?? Blk/Wht and Grn/Wht. Looks like they went to the stock ECM. With that being gone what do I do with them?

Re: My 1989 IROC LS1/4L60E swap
The 98's used a dummy light in the cluster for the resistance. You can grab a 5 pack of resistor for a buck at radioshack
25th is correct, BLK/WHT is grd, GRN/WHT is 12v controlled by the PCM

Re: My 1989 IROC LS1/4L60E swap
One more out of the 98 PCM.??? R32 (org/blk) is for park neutral sig. Im assuming there is a wire on C207 that would go to the N.S.S. in there.
Opinion?? There are many wires that look like they could be used in the C207. I know the years changed these things alot so I will put what I have and see if you can tell me what they would be best for or to delete.
A - Brn - Emission ctrl.
B - Blk - Fuel Inj.
C - Brn/Wht - Ign, SES,Tach
D - Tan-Wht - Coolant Fan
E - Wht/Blk - Ign, SES, Tach
F - Pnk/Blk - Ign, SES, Tach
G - Blk - Fuel Inj.
H - Tan/Blk - Engine data and TCC
J - Org - Emission ctrl.
K - Brn - Idle speed ctrl, fuel ctrl and data
L - Dk Blu - Pass Key
M - Blk/Wht - Idle speed, fuel ctrl and data
N - Org/Blk - Idle speed, Fuel ctrl and data
As always, Thanks in advance. G.

Looking good... I'm avoiding the wiring on my swap too... but then again with my customers and my shop I can't afford to play with the car at all... cost of doing business though I guess....

Me Too. From what I have found on the car D is a trigger wire for the cooling fans.
H - I am very curious about. I did not lable these before I cut them so I'm not even sure whitch wires from the C207 went to the engine compartment and others went to PCM. Rookie move! I ban myself.

I hear ya! If We had some work mine would go on the back burner.. At that time of year again where folks just dont want to spend $$ on their cars. I run a Transmission shop and It has been a roller coaster the past few years! I wish I were so busy I did not have time to work on it, the pocket book would like that but for now I need to get this to where it will move on its own power and get it off the lift ( for when we do get busy).

Re: My 1989 IROC LS1/4L60E swap
A little more done today, Wires are everywhere but they are all hooked up except for A/C stuff. With the key to Accessory, My lights and buzzer are there but when you turn to start- Nothing. Gauges move but no solenoid. Looks like I will need to by-pass the Starter relay for VATS on the car. I Need to brush up on that one. Still don't know if the Nutral Park wire on the PCM has to be hooked up to something. Must go find that topic. G.

Re: My 1989 IROC LS1/4L60E swap
OK, got the relay bypassed and now it will crank. Trying to build oil pressure is realy making me nervous! No plugs, coils or fuel. Been cranking on this thing for a good 4 minutes total in 15 sec intervals and still nothing showing on the gauge and no oil up to the heads yet! This sucks! I feel the crank and rods are gonna run out of assembly lube and scar the bearings............... Any suggestions?

Where on the block do you hook up such a thing? Pressurised tank that is.

Hook it to the same place your oil pressure guage threads into, or any other oil pressure passage you are able to tap into. You can also drill and tap the small block off plate above the oil filter on the pan, and use the pressurized oil prime method there, or use a line guage there as well.

Re: My 1989 IROC LS1/4L60E swap
I rented the pre-lube kit from Napa and will tap the port on the block just to the right of the oil pump (left front of engine) . Only problem is that nobody (Parts houses, Friends, Friends of friends) has the adaptor fitting to go from the pipe threads on the hose to the metric threads on the block. They just say to fill it up and fire it up. I did not want to damage the bearings at start up.
Know where I can score a fitting?

I read somewhere on here that capping the waterpump is not good. I found a hose that worked. It is 5/8 hose so you have to use a little hose stretcher on one end. I also see that this Pt# will work as well -gates b87629.

Re: My 1989 IROC LS1/4L60E swap
I did get a little done today.
Put the factory plug back in.
Friend of mine had this port he tapped so I used it.
And why not, They claim to make more power..
Got the radiator in and fans on. Spent 1/2 the day looking for a fitting that doesn't exist. I believe The Autometer Number above is the correct one. I couldn't wait that long.
A few steps closer.

Re: My 1989 IROC LS1/4L60E swap
OK, HELP! What Transmission dipstick and tube are most of us using for these swaps?? Have we found an OE that will work (Be able to mount to the trans and clear the hood).
Trans is out again. needed to get the correct dipstick tube and need to lengthen the O2 wires. Found out the hard way that with those wires short I would have to remove the trans to plug them in! I like it tight, but not that tight!
