This is what I did about my a/c interference, and I live in Texas, I don't know what I am thinking

That is all going to get painted, if anyone is wondering

jk Hector... yes it gets rather hot up here and the humidity is fukt... today was 104 F. Other Canadian facts you may not have known:

YES we get winter AND summer
NO I do not have a pet polar bear
NO I do not live in an Igloo
YES our beer is like moonshine.
most Canadian girls at 15 year old can drink most 19 year old men under the table
Steroids are legal to posses and use you just can make or sell them (this goes with a slue of other drugs)
Prostitution is Legal here (you just can't live off the evails of...)
A gallon of gas is almost $1.30 more here than across the border
Yes our health care is free (but taxes are super high)
You can't sue anyone and win cause it breaks down to hearsay somehow.
Most of the funniest guys in the movies or Comedy come from Canada; names like Jim Carrey, Mike Myers, Howie Mandel...


NOW back to this install any pics????

I know this has nothing to do with the OP swap, but just reading through this and seen this...
You get caught here with that,its ranked up there in the worst clssified drugs on the planet,about like having heroin or something to that affect....lol
Crazy how laws are different across the street....

I don't know what that comment is all aboat. It must be aboat us southerners and how we like to inbreed. Yup, that must be what it's aboat.

ROLMFAO... its funny your from GA. I was there once in Atlanta for a S.P.L. competition and we loved it there. I sat with a guy and he seemed pretty normal and we joked about Igloos and Inbreeding. We laughed about how some people think a 2 min drive across the bridge = 12 ft drifts of snow. (yes we actually have 12 ft drifts of snow and sometimes have to shovel off the roof of the house first but that is WAY up north. So next time your having a bad day just say to your self "hey at least i don't have to dig out my house today") and how buddy ran into people saying wow its sure not like it is on TV down here... After a few Canadian brew (he was so hammered he was slammered and I was rather tickled myself at that point) he went on to tell me about the difference between a "Redneck" and a "Hillbilly". He said a Redneck loves the country and prefers the quiet over the busy city and city folk; NOW the term hillbilly is used when someone who looks like the photo's you see and does date his cousin... We (rednecks) even call em Hillbillys down here..... after two more brew he had all 6 of us educated on the difference between the two and said now educate everyone up there in Canada about the difference and I will educate everyone down here that you guys really don't have pet polar bears and that ya'll DON'T live in Igloos (well not most of us anyway)...


While in GA I did notice you guys have some pretty good looking (and really friendly) county women...


Good times there...



AND NOW BACK TO YOUR REGULARLY SCHEDULED POST....

[HectorM52]

Awesome. Even I didn't know all that!!

[94ss s10]

any one running the stock s10 rad with e-fans im trying to figure out if that will be enough to cool it, using the caprice's reservoir and stock hose routing, also will i have a problem with the filler cap on the s10 rad poping off to vent the caprice rad doesn't have a filler on the rad its a sealed system

[JonathanMaples]

im running the 4.3 s10 rad it works fine for me so far it'll creap up to just under 200 but it stays there im running a tauras fan with a temp switch in the rad to come on at 185 and cut off when it cools it down to 165(if u use a temp switch make shure its working and on a relay),im also running the stock 195 stat

Only if the orginal engine had fuel injection, and not throttle body.
The throttle body pump only puts out 13psi, and not enough volume.
The LT1 requires 41-47psi pressure, and I'm not sure about the volume.
We got an in-tank, aftermarket replacement pump from Advance auto that
puts out the correct pressure and enough volume.
Don't know about the in-tank pump for CPI engines, but they put out too
much pressure! Use the pressure reg at the engine for control.

Won't work the way you are proposing. If you are using the Caprice reservoir,
you need a sealed radiator, like in the Caprice.
If you use the S10 radiator, like I am, you need to do some hose re-routing.
I am using the stock S10 reservoir bottle. It hooks up as before, with
overflow from radiator to upper hose connection and drain line as before.
The change comes at the water pump. The 3/4" heater feed line must
have the pressure reducing valve in it. On a Caprice this is located
AFTER the reservoir line, buried in the heater hoses running along the
right inner fender. It is a small black cartridge, crimped inot the heater line.
The throttle body water line coming to the front in my case got re-routed
into the fitting on the face of the water pumps of the Z28 variety. The
pumps used on the Caprice do not have this port!
If you need a pic, I can dig one out to show you. This is a high (15psi)
pressure port. Depending on how far you set-back the engine, will determine
how much room you will have up there.

Not true with an LT1!
We set the engine/trans back 1", and had the right front corner of the
oilpan contacting the crossmember. Now some of this depends on how
far down you set the engine. We have my engine set at less than 1"
above the crossmember, and kept a 4 degree or less angle on the drive line to prevent any problems with the driveline.
We "massaged" the interfering corner of the oilpan to provide clearance.
It does no harm to the internals! It does not take much. Use the contour
of a large diameter socket laid against the corner and tap LIGHTLY with
a hammer. You only need about a 1/4"-3/8" indent, and then only at one point!

Thanks in advance. I can weld anything so if i have to cut and relocate some sensor on my manifolds believe me when i say i can do it.



Best Regards

Yes you can use the stock manifolds, if you relocate the engine. BUT,
you have to remove the heat shields on them, they take up too much room!

[rkmdogs]

Here is a pic from a different angle that shows the hose arrangements,
especially the one from the throttle body down to the water pump.

In addition to the previous threads I have posted on this matter, let me
fill you in with some pics on the water pump issue and solutions in the pressurized part of the cooling system.
First is the Caprice or "B" body LT1 water pump. Notice that the lower left corner of the pump has no opening.


Now we come to the "F" body or Camaro water pump. On the Z28 engines
they had a provision for routing water lines to cool at the oil filter. This required a fitting at the lower left corner of the water pump. This was a
right-angled hose connection, which hooked either to one of the cooling lines to the oil filter, or the upper hose of the radiator if the cooling option was not used.


In an S10 conversion where front space is a major issue, we decided at first
to modify a Z28 pump by blocking off this port, to create a shallower profile.


But then, see that little tube sticking out of the lower left corner of the
throttle body? That is the return water feed tube for the heating of the
throttle body to prevent "icing: of that item, preventing the throttle plates
to move. Some people block this off for racing, but if you drive on the street
in cool or damp weather you need it. Unless you are using a closed radiator,
like on a "B" body, where this port is fed back to the reservoir tank, you
cannot do the same if you are using any radiator that has "venting"
provision. This is the type of radiator most cars and trucks use, as is the
case with the S10/S15 trucks. So this high-pressure port has to feed back into the system somehow. We chose to do it like the Z28, by removing
the plug we had put into the water pump, replacing the plug with a
right-angle barbed hose fitting and plumbing a small line from the throttle
body port back to the water pump.
That's what you see here.


And that is how you solve that problem!

[HectorM52]

Great info for anyone that is confused with hose routing...

However, you keep saying "lower left" when that looks like "lower right" if you ask me????

Sorry about the confusion Hector. The directions I am refering to are relative to the car, not the pic. That is, when I say "lower left", that is the left side of the car.
Hope that clears it up for you.

I have been told that you should not have more than 5 degrees slope
on the motor/trans assembly or you will have all sorts of driveline
wearout/vibration problems.
My install is @ 4 degrees. We are not up to being ready to fire it up
yet, but the other factor you need to watch out for is side-to-side level.

This all controled by motor placement and what you use for motor mounts.

[94ss s10]

thanks for the info on the cooling system im going to try to use the s10 rad with a over flow tank, keep the caprices hose routing remove its tank and just conect the two hoses together that went to the caprice tank and see how that goes, but for fans i have about a inch and a half clearence between the ferthest point on the motor and the rad so im stuck putting fans on the out side of the rad i got my eye on a set of 12.5 inch by 3 inch fans on a 1990 bmw in the junk yard that look like the would do the job

[94ss s10]

what brand and part # are thouse rad hoses they look like a good fit

[rkmdogs]

Quote: Originally Posted by 94ss s10

Those are NOT intact hoses as you see them in the pic!
They are hoses that were purchased from Advance Auto parts, based on
comparing their profile with a template, and then trimming to the shape
you see in the pic.
I do not know what they were for originally, but the label #'s on them are:
71794 and 70724CS.
You can see those numbers in the pics.
Sorry that I don't have more info.
P.S I did not use the Caprice reservoir bottle because in the conversion,
like on all injected S10's the ECN sits on top of the reservoir bottle!
There is no provision to mount it there on the Caprice bottle. The Caprice location was under the air filter box at the left front corner of the
engine compartment. Won't fit there in an S-10 with the washer bottle
there!

I think you might be asking for trouble. On the Caprice, one hose came from the throttle body water line. The other line out of the bottle went to a "T",
and one end of that "T" line went back to the water pump and the other end
went to the pressure reducer and then on to the heater core. If you hook
that 15psi line from the throttle body exit direct to the heater core line,
you could blow the heater core!---- and that would be a BIG mess, inside
the cab. Chevy warns that the heater core is not supposed to see more than
5 psi !

[94ss s10]

i think i still have the pressure reducer in there, so should that not still regulate the pressure

[rkmdogs]

It all depends on how you do the routing.
If you still have the pressure regulator in the 9C1 hose, it is a small black
cylinder in the middle of one of the radiator hoses. It has an arrow on it and the words "heater core" molded on the side of it.
Just make sure that it is on the inlet side going to the heater core.
Have fun!

what did you do with your oil cooling lines

[HectorM52]

I removed mine and put them on the shelf. They keep that thing cool.

[94ss s10]

really? think its going to stay cool enough

[HectorM52]

The shelf or the motor??

Just kidding. Yes, it stays cool. That's a function of the fans + the radiator.

[94ss s10]

does anyone know if that your trans. is in limp mode that it wont go into reverse, i have'nt really played with the linkage yet and im not yet ready to take it for a test drive so i dont know if i have all my gears but it does shift into drive by the way this is a 4l60e trans.

[slyfox]

ok I am sure some place people on here asked the question but here goes

i am looking at a 2000 extreme with 2.2

i can get a good deal on a 93 lt1 motor with 700r4 trans

i wanna keep it simple the lt1 is tbi but there is a kit to change it over to carb. yeah carb is not prefered but i dont wanna mess with the computer part of it i know nothing about.

so with that being said what will i need to do for the lights gauges the things you need to work ?? i would rather keep the stock dash but if i have to remove the cluster and put aftermarket gauges in i will

i am prety sure i am just gonna run a fuel pump on a switch with a regulator or if the stock pump will work i will use that and have the cooling fans on another switch..

i know i need motor mounts, headers, the carb conv kit, radiator maybe a driveshaft ? is there anything i am missing ???

anything else i need to know would be great input

thanx in advance
Brent

[HectorM52]

If you're willing to shell out the cash for a new intake, carb, and all the parts necessary to go carbed then why not put some cash into a wiring harness? And you're willing to put a switch onto 48 different items that are already controlled by the PCM!! That's nonsense!

There are 50 LT1 S10's on this site - start gathering parts and I bet a ton of those guys will help you get it in. But I would think starting your own project thread would be the way to go.

Feel free to PM me if you have any specific questions. I would say that searching would be your friend as far as all the swap parts go.

Good luck.

First off Brian, LT1s are not TBI engines. They are direct port injection engines!

The other things that you need are a good dose of common sense, and tons of money!
As a start read the JTR handbook on line about this conversion, but take that
advice with a grain of salt. 50% of it is wrong!

[slyfox]

ok so can some one tell me where to get a harness for a 93 vette motor then i been all over and i only see for the 94 and up lt1 motors current performance only does 94 and up unless there is another site ??

The optimum angle for installing the motor is something less than 5 degrees,
to prevent alignment problems. Mine was set at 4 degrees. In order to do this, you have to set the engine back 1", and to the right 1".
You need to go to the www.V8S10.org website for more info. My whole install file is there!
