Thread: Well I'm Starting My Top Swap, Just Some Questions

First I will be swapping my engine harness, Got a GTP ECM w/4t65-E Std tune, Headers, Homemade intake, and a full top end.

Ok now the questions...

1: Is there a good write up on where the sensors and vac lines go?

2: The headers I got from ebay had this extra stuff with it and I have no idea what for. See Pic

Hit up Blue...he has the vaccum pics.

that stuff...I always toss aside.

I searched for blue but didn't know what user they were

First link didn't work, thanks for the second. My other question is the fuel rails, will my l36 lines connect to the l67 rail?

Sweet. How does the Harmonic Balancer come off, i can't get my jaws around it to pull it

This is what they said i would need so far this is the only thing anyone has in town
Buy K Tool International Harmonic Balancer KTI70344 at Advance Auto Parts

The puller i rented from o'reileys had the special bolts in the kit. I bought them before anyway but the kit had them. And yes the fuel lines will fit, but one of mine kinked so be careful. I have a lot of other info if you need it.

I was under the impression the L36 fuel line did not have a source for a return line. The L67 rails require one. Then again I'm not too familar with the L36 fuel system.

So far I'm good on questions. Thanks everyone. I'm sure when i start putting it together I will have alot of questions

There is a return, its just in a different spot than the L67 one.

Just woundering if it's safe to drop pulley sizes with top swaps?

Yea you can drop pulleys but you need to do more mods than the equivalent GTP.

Right now I have the tb ported to 75mm and cold intake, the charger ported, lim to match. headers no cat, 3" all the way back then spilt to dauls
