Engine build up??

[hellix2484]

OK so I have been studying the swapable parts guide and this is what I have come up with for my engine build.

00+ engine Block
93-98 Crankshaft
96-97 head/manifold

forged rods
Hyper pistons


I know there are some things that I am missing, but this is just a rough list.

What Wiring harness/PCM will i need to use? This engine is going into a 2001 SC2.

probly a pcm and harness from a 1st gen cause of the head/manifold

on all that you listed, what's your reasoning?

if you're spending the money on forged rods get forged pistons too don't cheap out.

00+ block - stronger and all the accessories from previous years fit. Also, The internals from previous years will fit in the '00 and up blocks.

96-97 head - Linear EGR valve, otherwise compatible with 91-94 heads. Compatible with any year block.

93-98 Crankshaft - lighter weight.

I already have a set of hyper pistons so I was just going to use them but I am guessing that CP pistons would be the best?

[slowion2]

CP, JE, Ross, Wiseco, all are good

people debate on which crank is better, 99 and up has more counterweights and is supposed to be smoother in the higher RPM's, something to consider.

95-98 heads are all compatible with the electric egr.

[hellix2484]

where would I get a set of CP, JE, Ross, or Wiseco pistons?

do you have any suggestions?

I currently have a 91 engine block and Crankshaft, but I have heard a lot of bad things about the 91's

I also have a 91 head/Intake manifold/fuel rail/injectors.

Could I uese any of that?

[jts749]

the 91 crank will only work with the 91 ecm

[slowion2]

the 91 crank will only work with the 91 ecm

no, it will work with the 91 block only, I think maybe 92 also. there signal for the crank pickup is in a different place than all other blocks, so you need to have the same year crank and block in that case.

if you couldn't source a 02 block, you could get the tie plate from one to strengthen the bottom up.

[SupraCharged007]

its not the block that matters. The reluctor wheel on the crank is the issue, its 10* off IIRC. You can only use a 91-92 crank with a 91-92 pcm. IE, through that crank away.

if you go with what you said in your first post, you can use the stock harness and PCM from the 01, You may have to splice on a couple connectors for fuel injectors depending on which ones you have now and which ones your injectors will have. Other than that, everything pretty much swaps up. Only thing I would worry about is the fuel lines cause if you look at the feed line on the 00+ plastic IM, its a good bit different than the 99 and earlier. Also you'll prolly need a new throttle cable if memory serves me correctly.

[slowion2]

you sure? it was explained to me that it was the pickup on the block or something to that extent

I remember bill deebs using a 91 or 92 ecu on one of his builds because it was less emissions friendly possibly? this was back a while ago too.

[Jason96SL2]

It's the timing like he said. Are you going for an NA build? If so, the hypers may not be a bad idea if you're not going over 10.5:1 compression. Some lightweight rods and 8500 rpm might actually make 160hp in a saturn. haha. If you want real power get some forged pistons and boost it.

yea, all the blocks are the same more or less. The sensors are the same too as far as I know. The reluctor wheel attached to the crank is different though. Also the code in the pcm is changed up to reflect the differences in the reluctor wheel [img]{SMILIES_PATH}/wink.gif[/img]

[hellix2484]

so basically I need to match the Crank with the PCM and the wiring harness with the Head.

And I can scrap the block and the head from the 91.

What about the intake manifold/fuel rail/injectors from the 91?

What about the valves and springs from the 91 head?

Yes I am planning on boosting in the future. It may take a year or two but I will get there eventually. LOL I like to do my homework first so I will be asking a lot of questions so bear with me.

I have also been reading a little in Maximum Boost by Corky Bell. From what I have hear it is the book to read when turboing.

[jts749]

the manifold, injectors, and fuel rail are the same as far as i know

[hellix2484]

the only difference on the injectors is the impeadence. Low or Hi.

Which doesn't really matter since I will be replacing the injectors.
