I am looking at a 3800sc engine. The owner, an older gentleman got a crate engine as payment from someone who
owed him money but he does not now what series it is. How do you tell?

Thanks
Keith

It's usually written on the engine cover but if not the easiest way to tell the difference between a series II and series III 3800 engine is to look at the the fuel rail. The fuel rail of the series II engine has a regulator on it and a feed and retrun line. The series III uses a returnless fuel injection rail with only one input and no regulator on it.

Sorry to intrude. Dennis, do you know the whereabouts of the 3.4l turbo write-up you did that is listed on the spacecoast site? I can't find it using the link provided.

Thanks

Now.....Back to your regularly scheduled program..................................................................

I would just look at the supercharger/fuel rail setup. series 2 will have a bolt on the middle of the supercharger that bolts the rail down. Series 3 would have a supercharger with all the ribs seperated,

If I am not mistaken, The series 3 s/c motor comes with a genV eaton M90 and the series2 comes with a Gen3 M90.

The throttlebody on the genV is bigger and the blower is more efficient. (from what I understand, the pcm has more torq management in it and is more difficult to deal with also) If you are thinking about swapping into a fiero, the series 3 throttlebody wont work because it works electronically and doesn't use throttle cables.

The block is basically the same, with some minor differences (such as how the a/c bolts up). The series 3 has forged rods and the gen 2 has cast. The fuel lines on a series2 has a feed and return, I think the series 3 only has a feed line.

The LIM (lower intake manifold) has a slightly different opening for the different blower, and I heard the Heads have slightly bigger valves in the series2 but I don't know if that is fact or speculation.

The series 2 is a L67 and the series 3 is a L32.

here is a pic of a gen3 blower (from L67 on top) and a gen V (from a L32 below)

Can you take the throttle body from a series2 and bolt it to a series3 instead

not without an adapter. I know they are available at www.zzperformance.com and www.intense-racing.com
(cant seem to link to the Intense one but its under the induction section)

besides just getting it to mount up, there is the pcm problem this presents... the series3 pcm isnt programmed to use a cable throttlebody, or the sensors it has. I am not sure how to get around this.

If i get the wiringharness and ecm from a series2 would that work

How much money is he asking for this crated engine?

Series II is cable throttle control and Series III is electronic --- or cableless throttle control. Therefore, to put a Series III into a Fiero instead of a Series II, aren't you going to have to spend huge piles of time, effort, and money to essentially attempt to change a Series III engine into the more workable (for a Fiero) Series II engine?

It doesnt seem like it would work for you in this case. You could probably get 800-1000 dollars for the supercharger and LIM if you were to take them and sell them on ebay or www.clubgp.com.... Not to mention that the block probably wouldnt be too hard to sell for 400-500 dollars also. You could use that money to pick up a low miles L67.

We've discussed this on other threads so here is some info.
The series II and series III engines are totally different animals. To operate in true series III mode you will need a TAC (accelerator )module), regulated returnless fuel pump , returnless fuel rail, and many other items needed that interface to the 2006 PCM. If you replace all the series III sensors ( MAF, O2, etc) then you could use an earlier PCM and harness but these earlier PCM's do not have the capability to shift the 2004 - 2006 4T65eHD transmissions that are behind these engines. You could conceivably use an earlier tranny or change the line pressure solenoid on the newer transmisson to the earlier one. WE are now investigating IF this can be done.

I have a 5spd right now and want to keep it or am thinking about Archies 6sp.
I am not planing on going to a auto. Thanks for all the input

if it is a series III you want it like they said above all you need is a tb adaptor and run a series 2 tb or a north star with an adaptor, if you need a harness and pcm call ed morad 216-798-6902, he can get you a gtp harness and pcm for like 300.00. you want the gen v charger it has like stated above greater effecenicy and better output. everyone is swaping gen III to GenV's in the gp world if ouy have any questions he can help you out hes been parting out grand prix gt se and gtp's for 7 yrs that what he specializes in.

Turns out that it is a series 1. He want 2k for the engine and trans, accesories, harness, PCM and scanner to read engine codes.
Plus a running 87 gt parts car. Are there any issues witht he series 1

Series 1 is not interchangable with any of the latter years. And there is little to no aftermarket available for it.

You might be able to mod them enough to keep up with a stock series 2 setup, but it would cost you about $600+ for that.
