Junkyard Mods

[theoutlaw82]

I'm trying to compile a list of junkyard mods for the 1G and 2G in order to make a tech article. Basically any parts that you can swap from other cars to this one that are an upgrade. If you guys know anything please share. So far I have.

6. 1G 5spd 14B turbo (if you have an auto)
7. 2G Mass Airflow Sensor
8. 92 and up 4 bolt rearend swap (for 90 to early 92 awds)
9. 92-94 M/T D intake cam and C exhaust cam.
10. 1990 Oil filter adapter with external oil cooler.
11. 1G 1.8L EGR block off plate
12. 1G Manual Steering Rack
13. 1G Base Model Doors (No power windows or locks reduces weight)

2G Upgrades

8. EVO oil filter housing for external oil cooler
9. 2005 Outlander brakes
10. 1G 1.8L EGR block off plate
11. 2G AWD Front Brakes ( 2G FWD)
12. 2G Base Model Doors (No power windows or locks reduces weight)

For 1g-2g o2 housing.

 

[MEz]

1g BOV for 2g

 

[Airsign89]

Although its rather obvious, 14b as upgrade to t25.

 

[theoutlaw82]

For 1g-2g o2 housing.

Thanks. Its added.

 

[Bud92gsx]

For a 2g even a 13g is an upgrade.

1g auto mods are 5speed ecu, fpr, manifold 1g/or 2g, injectors, and 14b.

 

[jimbob_843]

2g mas for the 1g guys. And also 2g exhaust mani for a 1g

 

[Airsign89]

Although its not a direct swap and I've heard its difficult, 2g(awd that is) transmission in a 1g.

I forgot, the 1g(92-94) manual transmission cams stamped with the "c" and "d", are a tiny bit more aggressive then the 2g cams.

manual fpr? auto have higher fuel pressure? a manual fpr will cause a auto car to run to lean with stock 390's

 

[Bud92gsx]

manual fpr? auto have higher fuel pressure? a manual fpr will cause a auto car to run to lean with stock 390's

Yes manual ecu,fpr, and 450's.Will not mess anything up.1g 450's flow around 410cc's with the lower fuel pressure.The auto's run 42 ish.That's why you have to swap all of those things or the car will run rich on the auto fpr, and retard timing during brake boosting.

For 2gs, they run 42 ish and same injectors and pressure.And 2g's flow 450 cc's.

I did forget to say 1g manual cams are a tad more aggressive on adding that.

A 1g head isn't an upgrade for a 2g, a 2g head is an upgrade for a 1g because of the smaller intake ports.

 

[Airsign89]

A 1g head isn't an upgrade for a 2g, a 2g head is an upgrade for a 1g because of the smaller intake ports.

I was gonna say that but because there has been alot of debate about it decided against it. Also, in that same arena, isn't just swapping, without any portwork, a 1g intake manifold onto a 2g not really an upgrade because the shape of the runners aren't the same as a 2g? This is a question, so please don't get angry if it is completely incorrect.

 

[Bud92gsx]

A 1g head isn't an upgrade for a 2g, a 2g head is an upgrade for a 1g because of the smaller intake ports.

Stock for stock and lower rpm power yes.

But you know as well as I do, this is very debatable.So yes it could be marked down as a stock upgrade for 1g's.

And you would have to open the intake ports to put the stock 1g IM back on.Why throw a complete 2g head with 2g IM and tb on a 1g?

 

[NeMiZiS]

A 1g head isn't an upgrade for a 2g, a 2g head is an upgrade for a 1g because of the smaller intake ports.

I was gonna say that too.

 

[Airsign89]

Ok last one from me, its for 1gb and all 2g's, the 1990 oil filter housing with the external cooler.

 

[91stocker]

Yes manual ecu,fpr, and 450's.Will not mess anything up.1g 450's flow around 410cc's with the lower fuel pressure.The auto's run 42 ish.That's why you have to swap all of those things or the car will run rich on the auto fpr, and retard timing during brake boosting.

Why would you want less fuel pressure? I would think the auto fpr would be the upgrade to the manual. More fuel pressure with out buying a 200 afpr.

 

[theoutlaw82]

So after some research I removed the 1g head swap on a 2g. Anybody know of any gear swaps or suspension mods?

 

[gofer]

2gs can't run a 90 OFH unless they've done a 6-bolt swap, they can run an Evo III OFH though.

The 2g IM is only an upgrade on a 1g if they also switch to a 2g head, too.

-I think you should add 2g AWD brakes for a 2g FWD.
-95 EPROM ECU
-99 ECU
-3G Eclipse brake booster and brake master cylinder

 

[Airsign89]

Gofer, thanks for the info, I wasn't 100% and shouldn't have posted that as it relates to 7 bolts. Also good info on the evo III OFH.

 

[Bud92gsx]

Why would you want less fuel pressure? I would think the auto fpr would be the upgrade to the manual. More fuel pressure with out buying a 200 afpr.

You don't, correct.But if the manual ecu is used to 450's running 38ish puel pressure.Why run 42+.You a tad rich with no tune.This is a stock upgrade no need for a safc or anything.

If anyone can figure out how rich you would be with the auto pfr, and how much damage you can do, please let me know.

2g's can use 3g rear upper and lower control arms.

2gs can't run a 90 OFH unless they've done a 6-bolt swap, they can run an Evo III OFH though.

7 bolts can also use Evo 8/9 OFH.

1g AWD brakes can also be added for a 2g as long as you get RRE adapter brake lines (1g brakes use screw in lines instead of banjo lines).

 

[psycho]

2005 Outlander brakes are an upgrade for a 2g.

The calipers are the same (2 piston) as the GSX. The bracket is taller, allowing the use of 2005 Outlander 11.6" rotors.

Caliper Bracket P/N: MR307282

 

[theoutlaw82]

1g 1.8L EGR block off plate. Will fit both gens.

 

[DSMReviver]

Snowborder how is 3g's upper and lower control arms an upgrade? I am not familiar with this..

 

[snowborder714]

They're tubular and potentially a bit lighter. I'm not sure if I've ever seen weight comparisons on them yet though.

If anything, they just look a lot nicer
