Thread: Almost done with top swap, but in serious need of help

Hey guys, we got all the hard parts mounted except for the harmonic balancer... we cant get the original off the engine. Thats problem number one.

Problem number two... the left engine mount (side closest to pulleys) will no longer fit, there is only one hole on the from head for a mount.

problem number three... We dont have vaccum line configs (I would really appreciate some pictures if you have them of the routing and where things go and what they look like)

problem number four... The belt assembly doesnt make sense to me. I feel like Im missing a pulley somewhere or I have an extra, I cant really take a picture because it was in the car and is difficult to show the whole assembly.

problem five... there is no PCV valce connection, so there is jsut a leftover connector on the harness... is this normal??

Please guys, Im almost done, I need my car back ASAP, I didnt think I would run into so many problems. If any one is in the area and willing to give me a hand in finishing, it would be greatly appreciated.

Are you using a pulley puller?

You should be using the mount from a supercharged engine. The one for non-supercharged engines will no longer work.

I see your edit. What PCV valve connector? The PCV valve on the non-supercharged sits under the MAP sensor. On the supercharged cars it sits in the blower.

Are you talking about the MAP sensor connector? Or EGR connector? Since there is no PCV connector we're playing guessing games.

I would assume he's talking about the MAP sensor, since it's the only one by the PCV valve on the NA engine. You need to extend that cable to connect to the new MAP sensor location, either splicing it yourself or getting an extension cable sold by most of the vendors.

yeah thats it, can someone show me where the map sensor is? and btw... the belt assembly is difference than above. The engine I pulled from is out of a 98 bonneville. There is one bracket with a tensioner and idler, but there's gotta be one more pulley by itsels... anyone know where this is, where to get it, and how it bolts to the block? the engine I bought didnt comewith that pulley. I made a thread not too long ago with a picture of the bracket I have.

yes we did try a pulley puller, but it just ripped the holes on the balancer open, and now they dont come out.

and where can I get the engine mount?/ anyone have a picture of it?

EDIT: would it just be easier to just get wiring diagrams to both cars, and then compare?

I know I need injector connectors as well, anyone know which ones I need and where I can get them? same goes for the MAP sensor extender.

The MAP sensor for the supercharged engine is a separate box that sits towards the back of the engine. You need this adapter to go from the non-supercharged connector to a supercharged MAP sensor:

(actually, you only need the black wire. That kit includes the connector for the BBV which isn't needed per say).

If you feel like splicing you could use this:

Here's the injector connectors by themselves:

you are using one MAP sensor that has one connector on it. you should be using the l67 MAP. you need to get an adapter that goes from the l36 MAP connector to the l67 MAP connector.

you have to use the l67 throttle body. youre going to need to do a hell of a lot of tuning anyway..dont tell me you got into this without having a way to tune for it

i dont know. try it and let us know what you find.

Your L36 throttle body is a decent amount smaller than a L67 throttle body.

^ that is what i was thinking but i never lined them up next to eachother.

Stock L36 is 65mm. Stock L67 is 69mm.

Honestly, sounds like more research before hand would've done you some good. Being prepared makes all the difference.

why did you send out the l67 TB when you could have went at it with a dremel for an hour and done it for free. if youre going to buy a throttle body or pay for one you might as well get a northstar then.
