x2 on you shouldn't have a 3800 in a 96- the only factory engine options were a 3100 and 3.4 dohc. If you have a 3800, it has been swapped.

As for a top swap thread- search for 'top swap', but I haven't found any thread that I really link people to that has a good walkthrough. Basically, you can tear the engine down to the block (obviously leave the block on down alone, and leave the front timing cover on)- following normal repair manual instructions; then put it all back together with the new parts. The only bad thing is, you need to know what parts to get, as the list is a little long, but you should be able to find that via searching.

 

Then maybe I am misunderstanding something. It says its a 3.4 DOHC 3800.

 

Post a pic please, where does it say that?

Since the 3800 was not a DOHC, that means it is a 3.4 dohc, which came in the 96 montes. Easy way to tell- when you pop your hood, if you see this:



its a 3800

If you see this:



it's a 3.4 dohc

 

Figured id throw in my $0.02 . A gtp pcm fits perfect n a 98z34 pcm tray. I figured out a CHEAP way to extend the fuel lines without cutting on the car. Find a donor car and cut the fuel line at the metal part leaving at least 2-3". Take a spare 3.1 fuel rail and cut off at the quick connect again leaving least 2-3". At the parts store grab two steel brake line quick spices, 1 3/9 and 1 5/16. Spice the corresponding rail end to the corresponding fuel line and poof there you go, clicp in adapters for a total of about $10

 

Hello Bumpin96monte
I don't mean to go the past but I working my way in the new generation going back to your past posting 3800 mod plans
I just bought a 1999 Chevy Monte Carlo Z34 w/3800 Series 2 with
200 BHP(Breaking Horse power)per GM specs I want to increase the power a bit for now then more later but in your article you are only talking about the L67 and the L36 now I don't know what Gm code it is but I don't think it's either one of the ones you mentioned maybe you can help me out with that and give me a list of places where I can get pair of headers Prom Chip (Hypertech. Jet) and some other quick mods i can do to it for now the plan is getting in to the low 13's with it like my (69 Impala Custom coupe 13.52 sec at 106 MPH) any and all info would be greatful please reply back to kc8trl@gmail.com

 

the 3800 series 2 not supercharged is a l36. i dont see you getting low 13's on a N/A car you will need either a supercharger or turbo. possibly nitrous could get you there but not sure on that.

the l67 is a 3800 series 2 supercharged fyi

 

I'm new to this community. Nice to be here. I would like some help if anyone can. I own a 98 z34 3800 series 2, about a month ago it took a crap on me upon further inspection it had thrown a rod bearing. After countless efforts to try and repair the damage with no luck. I caved in and found a SC 3800 out of a 99 regal gs. My question and it may have been answered and I'm just retarded. Is what do I need and can use off my old 3800 n/a engine and from my car to complete my swap.. thank you in advance for any help that comes my way.

 

New here also I am pulling L67 out of 2000 regal SC I am wondering if a wireing harness from it will work ??

 

Hey bumpin, could you send me the C100 pinout differences between 99 z34 3800 and a 98 ls 3.1 ? I am having no luck at finding the differances .
Thx in advance
