Down to the nitty gritty with my swap...

1) I have the original 87 wiper motor with the integrated pump (currently out of the car). Is this going to bolt back in or am I going to need the newer style?

2) I'm using stock f-body manifolds and one looks to have a spot for an 02 sensor. Will I need to have an oxygen sensor bung welded to the other side's y-pipe? Is the hole on the one manifold actually for an 02 sensor?

3) On the original harness - there's a brown wire that shows to be connected back to the voltmeter. John @ Speartech said this wasn't needed on the new alternator as his harness takes care of activating the generator from the ecm. Should this brown wire be grounded or should I just tape it up and hide it in the loom?

4) Where's the best place to get some fuel rail covers?

It's so close I can feel it... and it's a really good feeling

As for the hole in the manifold, it was to my understanding that its used for the AIR system. For FRC's, try LS1tech, eBay has some but they are pretty expensive.

Whats up 3.1. Glad to hear you are getting down the final pieces of the puzzle.

I can help alittle...

1) I have the wiper motor with the integral pump and have no clearance issues. Im not running a pump in that housing anymore though. Im using the 4th gen washer bottle, with the built in pump. Just used the connections in the wiper cover to power it. I think as long as you take the cover off while putting th emotor in, then put the cover on you will be fine. Ive heard some people say it wont fit...but mine has plenty of space.

2) Pretty sure the O2 sensors go after the stock manifolds...as was said. Not positive what fitting youre talking about.

3) I would say your best source for info on this question would be John at Speartech. Im alittle confused as to what exactly you are asking about there... but he's your best option I think.

4) Fuel rail covers. Here are the part numbers for the black covers, with red lettering. They also have the single slots on the left cover...if you need the dual slots, its a different part number.

LS1 fuel rail cover (from 99-02 Corvette, black, red letters), LH = 12561503
LS1 fuel rail cover (from 99-02 Corvette, black, red letters), RH = 12561502

Here's the dual slots...

LS1 fuel rail cover (dual slots) (from 97-98 Corvette, black, red letters), RH = 12556455

I ordered mine from gmpartsdirect.com. They are $33 a piece there...which I think is the best I found. You could try newgmparts.com also. Maybe even rock auto...but I dont remember them having them. Summit sells them as well...but I think they were more epensive than the GM site.

If you need one with dual slots...let me know. I have a brand new one that I took out of the box, looked at, and put back in the box. Ill cut you a good deal.

Good luck gettin her finished up!!

with regard to the manifolds...

the driver's side has the o2 bung in the manifold (toward the collector), the passenger side does not. you need an o2 bung in the exhaust, close to the manifold, on the passenger side if you are running o2s. i would run an sd tune and eliminate the o2 issues altogether.

everything else you asked about...meh, i have no input. i have no wipers or fuel rails haha.

Thanks for the help guys. I'm off to try the wiper motor, hook up some vacuum lines, and finish up the wiring. Then the long wait until my father is off from work again... to get it tuned and the exhaust built

Vacuum lines? Only vacuum line I have is the brake booster.


My washer is a little close but fits. Oh and I don't have anything special hooked up to the alternator but I am also running a standalone harness.

Mine is a bit more complex - I'm using the heater diverter valve as well as the original 3rd gen cruise control.

My test-fit of the wiper motor didn't go so well - the pump hits the engine. Ghettocruiser has indicated that he rigged his up to use a 4th gen pump with the original wiper motor, so maybe he'll chime in with some details.

Anybody have a good source for the pigtail that connects to the 88-92 windshield washer pump? I'm going to see about rigging this up (or swapping to the newer style washer motor)...

Like midnit...I dont have any vacuum lines. Just for my HVAC vents, and the booster. I did have my vac gauge hooked up...but havent done that yet because I have to re-do my pillar pod cluster when my wide band gets here.

Im curious about the diverter valve youre using. You're talking about the heater control valve right? Ide like to see pics of how you have it mounted and which one you are using, because I think Im going to slap one in mine this spring. I have the hard vac line that controls it just sitting there since I put the newer HVAC controls in my 86.

Anyway...about the wiper motor. When you pull the pump out, as Im sure you know, there are two connectors up in the wiper cover. The larger spade terminals fit in there perfectly. So I just wired the positive and negative of the external pump right into those, and dumped some hot glue in there to keep it secure and weather tight. As for which is pos/neg...you can kind of figure that out by looking at the back of the cover. One of the terminals will be coming from one of the cover bolts...the other from the electrical plug. I cant recall which is which off the top of my head. But that fires my 4th gen pump off with no problem. Works perfect!

I plan to pull my cover and maybe trim some of the pump housing part so it looks alittle better. But it doesnt look bad the way it is. I loomed the wires and tucked them out of the way.

Here is a super crappy pic of my clearance. The pump might hit my FRC...but it clears everything with the FRC off by a good amount. When I was thinking about using the old pump, I just planned to use a hole saw to make a nice clearance in the back for it. It wasnt going to take much though.

cool, im also beginning my 3rd gen lsx swap,
but im going with a 375ci 6.0
how much power are expecting from your build?

cam-

1. my stock 87 is on and works no issues. had to take it off to drop the engine in though and then re-install. I dont use the squirter at all my car never gets dirty or goes out in gack so its redundant

2. yes and yes.

3. this is the wore I ran to my stock 87 volt gauge

4. no clue I dont run em

What's the deal w/ that? 6L == 360 to 366 cid, and 6.2L == 372 to 378 cid. So, if you started with a 6L, I'm guessing that you're having it bored oversize?

Thanks for the info Justin. I've also got an 88+ wiper motor coming from ebay - so if I can find all of the pigtails to make it look clean I'll go that route...although keeping one I know works sounds just as good.

I tried to put the oxygen sensor in the driver's side manifold and ran into clearance issues with putting it in (not terribly tight down there - but tight enough not to let me move around an 02 sensor much)...I think I'm going to cap the one on the manifold and just have bungs put in both sides of the y-pipe.

I'm expecting stock LS1 numbers, maybe a little more with a free flowing catback. Then again - maybe my tranny choice will suck up a few hp At this point I'll be glad if it sounds like a v8 and moves under its own power. ha!

375ci 6.0 means .060 overbored 6.0 block= 375ci 6.2
6.2 blocks alredy come 4.065 bore thats why they call them 6.2
lq4/lq9 come with 4.00 bore or 6.0
by 6.0 i meant block
