bout damn time... there was about 110,000 on this engine.

 

Its going to be a very long, and expensive build from here on out...

[5speedz34]

That engine was rebuilt by Michael....wasn't it?

[z34_nut]

Yeap.

 

On the exterior... it lasted a very long time... but I'm going to be very interested on how it looks when I take it apart. I'll finally be able to put my own damn engine in there... thats pretty bad for an engine builder to put it off that long.

[5speedz34]

Ya, so it had like what 50k? What are your plans? You know there is a Fiero guy pushing 400 whp on a Turbo 3.4 with a tune, stock bottom end and ported heads/custom headers.

[z34_nut]

I was thinking Turbo as well.

 

These cars LOVE to breathe. I figure I'll do my port magic on the intake (or build a custom one), and on the heads... make this car wake up. I already got a hook up on pistons and rods... (forged).

 

Found some cam profiles, and also better springs + stainless valves for my application.

 

The joy of ODB 1 is the fact is MUCH easier to smog... and if I want to retain that, and make serious power... I need a turbo.

 

I fully expected this car to quit at some point (soonish) and have been researching some parts for it in my downtime.

[5speedz34]

When you say much easier to smog you mean mod it and pass smog? Or pass smog with mods?

[z34_nut]

mod it and pass smog? Or pass smog with mods?

 

i'm so confused... lol... its the same thing only the words are switched!!

 

Its both?

[5speedz34]

OMG wow.

 

What are you saying...Is this just a continuation of our AIM convo?

[z34_nut]

Apparently... lol

 

Anyway, its easier to pass smog with mods if you keep the ODBI system.

 

Less requirements, and easier to mess with... ODBI is a post 1974 owners dream.

[5speedz34]

So you can get away with more mods on OBD 1 as opposed to the same mods on OBD 2? Since OBD 1 controls less? Could you even get the car tested with OBD 2 equipment? I mean would a shop do that?

 

What do you plan on doing for a trans?

 

EDIT: How does testing work on California? Do you have to go to a shop that does testing, or a state office? I would try to find a "hook-up" with testing.

Who's there?

Why does it say I said that?

Good luck and keep us updated.

I'm not understanding what OBD1 offers vs OBD2. If you're talking smog laws, I can see an original OBD1 car being easier to pass smog due to higher smog limits, lack of computer check, lack of a need for sensors to be up and running (like post-cat O2's) etc. But what can you do with an OBD1 system that you can't on an OBD2 one? I'm not talking vehicle specific, I mean the system itself?

that sucks the motor went with so little mileage

[PCGUY112887]

OBD-II would actually be easier to pass emissions testing, the computer part at least, since it's very easy to fake OBDII testing.

[Brian P]

^ I agree with that at least for my application. My HC levels are high at idle and I am within a few PPM of failing emissions every year. If my car was a 1996 or newer I'd have no problem passing until there's a law against modifying emission-related computer controls.

Got a toasteed one in my 94 CSC, 93k on it. Sucks, nice car too.

[5speedz34]

Couldn't you run a emissions-friendly tune, and then change it back when your done?

[w-bodys_are_the_best]

I think you'd need a newer block to run OBDII wouldn't you? The motor I bought was a 91 installed into a 95 monte and he said the 91 block didn't have all the sensors a 95 did.

[GOT2B GM]

Why does it say I said that?

 

oops quoted the wrong person LOL

[z34_nut]

If I go Turbo, yes...

 

But that still doesn't get you around visual testing.

There's an ability to tune using your MAF sensor. Speed Density tuning would be proffered in my application, but we'll have to stick to the O2 sensors for a good one.

Unless you mean something different, OBD2 cars can tune via MAF all the time. I did that on my Olds, even though I did a SD tune as well. I'm thinking you must be referring to something else though.
