2G head swap CAS question

[ZacTsi]

Hey guy's I tried locating information for this topic but couldn't find much. My car has a burnt valve and I need a new head. It's a 95' Talon Tsi so the CAS is under the intake cam gear I believe. My question is this, could I fit any year 2g 7bolt or just 7bolt head on this car with no problem? Would my CAS be able to be fitted onto that head in the original spot or would I have to use that year and style CAS. Also is a 6bolt head an option or not? Thank you!

To reuse your cas, a 95/96 head is needed. 1g and 2gb heads dont have the provisions for the cas behind the cam gear. But a 1g or 2gb head can be used by rewiring the cas and swaping the spark plug wires around.

i have a 95 tsi also and i was gonna put a 1g head on also but to tell you the truth i would just go with a 2g head enless you can weld theres a tut on how to do the swap just type in 1g head on 2g block on google

If you get the head that had the 1g CAS, then you'll need to use that head along with the wiring harness for it.

Ok thanks guys. Yeah I've heard also the 2g heads flow better? I'll try and find a 95 or 96 head then, but if I come across a 2gb head I would have to use that style cas, and also extend the wiring over to that side of the head? Or do they sell a wiring harness for it like you said? and lastly change my firing order?

No it is not.

You can use any 95-99 Head, if you get a 97-99 head you just use the cam gear and sensor from your old head and bolt it to the new one and use the plug from your old one for the hole where the 97-99 one goes. This would be the easiest way, you wont have to mess with swapping plug wires, wiring harness, etc...

Why not just have a machine shop fix your old head?
You may end up with just as much money into another head than just fixing your own.

Crfidah the only welding you would have to do is if you want a 2ga cam sensor on a 1g head because there are no mounts for the 2ga sensor. Which for all that trouble it would be easier to go with the 1g cas instead.

Except for the fact that the 97-99 heads do no have the bolt holes behind the cam gear for his cas. It's been done by building up metal then taping, but it's much easier doing the ways I mentioned.

Then why are all the 2g heads the same part number?

 

[1995gstdsm]

wierd, i have a '98 head going in mine and everything is there to bolt my '95 sensor up

 

[1995gstdsm]

and my buddy has a '95 head in is '98 with no problems

No, there is no place to bolt up your original 95-96 CAS on a 97-99 turbo head, but there is a place to bolt up the CAS for a 97-99 on all heads from 89-99. You can always install a 1g CAS into that new head of yours.

 

[boosteclipse]

Neither my 97 head or 98 head has the bolt holes, that's why I'm running the 97 cas in my 95 gsx. May just be another weird dsm plan change in different heads.

 

[pauleyman]

Its likely a part number supercession. The original part numbers were not the same but they are now which they wouldn't do without the provision for the 95-96 CAS.

2nd gen heads are the better heads and you can throw a 1g cas on a 2g head without the ecu havin problems. Happy Re Searching thttp://www.roadraceengineering.com/1gcasin2g.htm this might help you out! Good Luck

Ok Thanks for all the help! I'm either taking it to a machine shop or putting in a lower mileage engine I found thats out of a 2gb so I guess I'll find out for myself If it's possible to use my 95' cas.
