95-96 Cam Angle Sensor Mod. HKS Cam Gears?

[Area1320]

I did a search and just came up with "this cam gear vs. this cam gear". No info on what HKS says about using their cam gears in a 95-96 4G63. The HKS Intake Cam Gear for 95-96 models require modification for Cam Angle sensor but fits Eclipse / Talon 1989-1998 Turbo 4g63. Any info on what modification needs to be done or has anyone done this? Anyone here have HKS cam gears (Both intake & Exhaust) on their 95-96. Please give me a hand thank you!

And now looking at the HKS Catalog for 05' it says 97-99 Models Require Modification For Cam Angle Sensor for the 264 or the 272 Intake cam.

And the catalog also says 95-96 for the HKS cam gears.

Anyone know?

i belive its the 90-94 and 98-99 that needs modification.

The 95-96 Cam angle runs off of an inner section on the intake cam angle gear. Any other year does not do this. I believe that the hks cam gear does not have this inner section. Hense, modification would be to either use a different year cas and invert the ecu reading, such as in dsm link, or to some how adapt the hks cam gear to support the inner section for the 95-96 cam angle sensor.

Exactly. The 97 CAS is the best choice. Some minor wiring but it bolts to the passenegr side of the head like every year but the '95/'96.

So the easy way out is a newer CAS re-wired in. But will the OEM ECU read this newer sensor or it's a must to do a computer now? 1G CAS possible at all like doing a 6 bolt swap?

You could use a 1st gen cam angle sensor like a 1990 with the nice long leads, or a black top one from the 91's, 92's. It will be much debated if your car will need a resitor in the baro wire or not to stop the random misfires codes from occuring, some cars throw fits, some fire up and go with no issues. This will require you to invert the spark plug wires from the normal firing order as well because the car will be sparking on opposites now.

I "THINK" the 97-99 CAS will work with your ecu but i'm not sure, sorry, just never tested it out. I know the 1G CAS will work however. If this doesn't make sense email me, just replying fast!

Just to save time "I did not write this". From RRE's web page this is the answer to the questions:
"If buying the 97 cam angle sensor parts new from the dealer you will need the following:

The Sensor and the bolt that holds it on.
1) MD327107 Sensor, Camshaft Position
1) MF140003 Bolt, 6mmx 12mm

The cast aluminum housing assembly that holds the sensor.
1) MD344722 Support, Camshaft Position Sensor
1) MD329502 Cover, Camshaft Position Sensor
1) MD329503 Gasket, Camshaft Position Sensor
3) MF140204 Bolt, Cover 6mm x 14mm
2) MF140025 Bolt, Support 8mm x 20mm

The piece that bolts to the end of the camshaft and the bolt itself.
1) MD327621 Cylinder, Camshaft Position Sensor
1) MF241261 Bolt, Camshaft

Expect to pay between $100 and $150 for the parts depending on the dealer.

We find it cheaper to modify the 1G head to fit the 95-96 sensor when doing a swap here in the shop. A guy in the middle of nowhere with out the equipment to weld aluminum and fit the 95-96 sensor under the intake cam gear will have an easier time by using the 97-up sensor.


To install the sensor fitting onto the end of the intake cam, you will need to drill and tap the end of the intake cam to be able to bolt on the 97 fitting at the end. All DSM cams have the drive slot there for the fitting, the drive slot is the same as the slot for the 1G cam/crank angle sensor. In the end of the cam there is a dish shape that makes starting the drill in the center easy. We stand the cam up vertically and use a drill press to drill straight down into the end of the cam. The casting drills easily and it could even be done with a hand held drill if you are experienced. Tap the hole with a 8mm x 1.25 bottoming tap. Even if you _slightly_ skewed the hole at an angle, it will not affect the sensor fitting. It is centered and held in place by the shape of the end of the cam, just do it.

The wire colors are the same with the two sensors. You want the black wire on the top, blue wire to the middle prong and red to the bottom.


If you are going to re use the 95-96 sensor, the most fun part is building up (by welding) enough material under the intake cam sprocket. These spots get machined flat and true so they can be tapped for a place to bolt the 2G cam angle sensor on. It's got to be perfectly located!

This is only necessary on the '95-'96 cars. The '97's have the cam angle sensor back on the passenger side of the head. "

Hope that helps.

Yeah i understand both of you thanks! What road do you guys take when someone wishes to put cams or cam gears for that matter in a 95-96 head?

On one hand i want to tap for the 97 CAS and on the other hand i just want to swap to a black top 1G CAS. (From what I've seen the black top is less likely to mis-fire on 2G's)

I find myself surprised to find this topic hasn't been explored further. What nobody with cams in there 95-96?

I personally used the "95/"96 sensor on the one head swap I did. The problem with that is you will need to get the steel plate for that sensor mounted to the cam gears you have that dont have the plate. It may be easier to use the other 2 options, due to that fact. I will post the link to the page, as I believe it also explains the 1g CAS wiring.

there you go

 

[Raph]

sorry to barge in on this, but does anyone have one of those 95/96 CAS lying around?
sorry again,but this is urgent..dsmer in need,all the way in europe.


i imagine that if you switched the cam gears on a hks cam with a 95/96 cam,it should work out fine.. (if you ordered cams for a 95/96..you would have the oems lying around..) does anyone follow what i mean?

 

[Area1320]

haha no check ebay for a cas. I have 1G's laying around not 2G's.

Anyway here's the link for others wondering about 1G CAS swap for a 2G head.

http://www.roadraceengineering.com/1gcasin2g.htm

I'll let you guys know how this goes or what i do!

But he wants to use the HKS cam gears, not the OEM ones.
Mike
But yea, keep us posted

 

[Area1320]

Yeah I guess i can't get everything since my car already comes with the eprom but whatever you know. haha

 

[Area1320]

Ok i got the HKS cam gears and all my new timing belt parts, 1G CAS (Black Top) and now just shopping for the cams and i'll let you know how it goes..haha. Why not do them both at once if it's not gonna work. haha. wooo

 

[flinguist]

I've got a '96 spyder with a 6 bolt and my '96 head w/ HKS cams. The shop that did the install used a 1G CAS to supply both the crank and cas signals, but the car was missing horribly. Fortunately I have DSM link, which has a feature that allows you to disable the misfire, and the car runs great now. Running a 1G cas can cause a misfire problem, because the 1G cas signal is not accurate enough for the 2G ecu.
