97+ 4g63 fit into a 95 body?

[Clipz0801]

Just wondering if my 97 4g63 FWD will fit into a 95 shell AWD. Any problems or things that i might need to buy or such.

Are you talking about the transmission or the engine? The block will go in just fine, but the transmission may need a different mount. My buddies 95 FWD Auto had a different tranny mount than the manual mount, so I'm not really sure. If you're swapping the entire engine, you may have to do something for the cam angle sensor since either the 2ga or 2gb didn't have them (can't remember)

The 97 engine will fit into the 95 as all the 1 one mount on the engine is the same, and the other 3 mounts are on the trans.

You'll certain need to use the awd flywheel.

Also, the 95 and 97 cas signals are inverted. I'd checked if they are interchangeable, as am not 100% sure.

my speed shop mentioned something about the cam angle sensor too... thats not too pricey to arrange is it? And as for the transmission... were keeping the awd trans thats already in the car... only arrangement is that i need to take the 2600 out of the FWD and toss it in the AWD. Could the stockflywheel stay in there for a bit, or is it best to change it?

You will HAVE to use the AWD fly wheel.

The 95 engine has a Cam angle sensor, and a crank position sensor plug on the wiring harness. The 97 uses a relocated CAS and an different signal plug. If you are going to keep the 95 wiring harness and CPU, you will need to do a CAS conversion by swapping a few pins on your ECU and you will have to run a 1g CAS. I would recommend that you swap wiring harnesses from your 97 and run the 97 computer to not bastardize your electrical system. I did the 1g CAS conversion and I hate it.

I'll find a link for you in a minute for the CAS conversion.

there is the vfaq that you will need to wire up a new CAS for the 95 computer. Read through it, I can't stress enough how much you should simply swap wiring harnesses and CPUs.

 

[Clipz0801]

removing the wiring harness and the ecu from the 97 and placing it into the 95 should be an easy job right? And if i were to replace the CAS will it be a problem later on for the engine when i want to up the performance?

 

[flashburn02]

You would have a high risk of getting random misfire doing a CAS conversion. Which is what my problem is. If you research "random misfire" you will get a ton of threads for people who get CELs on a 1g CAS swap.

It's not hard to do the wiring, but it is time consuming, you do have to do some work in the dash but its still plug and play though.

only other problem i can see is wouldn't the 97 ECU be programmed for a 97 FWD not a 95 AWD?

If you plan to get dsmlink or chip your ecu, I would stick with the 95 ecu (if it's still there, and if it's an eprom).

 

[flashburn02]

only other problem i can see is wouldn't the 97 ECU be programmed for a 97 FWD not a 95 AWD?

The only difference between the two CPUs are the FWD are throttled to 135mph and the AWD have no governor. I have heard talk of the FWD run slightly better fuel mixtures than the AWD CPU but I can't verify that.

And yeah, run dsmlink on a 95 CPU if you can. But if you can't afford DSMlink now i would run the 97. When you can afford it, DSMlink can invert the CAS signal for you on the 95 ECU

 

[Clipz0801]

Ok so let me get this straight, all from the begining.

-You want me to take the wiring harness off my 2g 97 FWD
-Replace the 95 harness with that of the 97
-Plug the 95 ECU in
-And run the DSMlink off of the 95 ECU

SO with that said i dont need to change the CAS and i should be good to go, right? And what ordering specs should i use for the DSMlink.

im running 580cc injectors
idle is maybe around 750-800
no clue wtf launch is
havent messed with rev limiter
and im running the MAF-T

thanks guys

 

[Clipz0801]

oh and if possible can i just run the SAFC-II and the MAF-T. I have expereince with tuning using those, but the DSMlink is a whole nother ballpark

 

[Dream On]

Yeah you can run whatever you'd like. I was just stating that if you use dsmlink in the future, you NEED a 95 ecu (eprom) for it to work.

 

[Clipz0801]

sorry for being a pain, but if i stay with the maf-t and safc-II i would need to change the CAS even if im using the 97 wiring harness and the 95 ecu?

 

[flashburn02]

OK: If you have money to burn, go with DSM link and the 95 CPU.

Otherwise, stick with the tuning you have now and the 97 CPU. If the 135 MPH governor really bothers you, you can desolder it from the CPU.
