Evo VIII Cams in DSM? [Merged 5-9] 8 cam

[acidxrain]

My friend is upgrading the cams on his evo VIII so he'll be getting rid of the stockers. Would the stock evo cams be a good upgrade for my car (97 gsx)?

 

[DSMSpyder99]

i dont think they will fit only EVO 1-3 are combatible with our 4G63. The 4G63 on EVO 4-8 are flipped versions of ours

 

[dsmturboawd]

^^ correct.

Hi,
I was wondering if you can use Evo 8 camshaft from HKS in an '96 Eagle Talon turbo.

 

[anoldsman]

Sorry but you can not. The timing sensor on the EVO VIII is on the exhaust cam, the motor turns the opposite direction, and the angle from the dowel to the #1 lobe looks to have been changed.

one of my friends at school is selling his cams off of his Evo8. I was wondering would they work in my car and what would be the gains?

 

[95TalonTuner]

no.

 

[Bohrn]

Evo 4 thru current cars have the engine reversed in direction, meaning that the cam gears are on the wrong side of the engine.

Evo 1-3 cams would have a much better chance of working.

If you want cheap cam upgrade, get 90-91 turbo tsi 5spd cams. I think they are better than the 2g cams and can be had for cheap

 

[Talon007]

1992-1994 5spd cams are the best, 90-91 are the worst 1G's.

 

[GS-T_racer]

thanks for the replys i'll look into the 1g cams

 

[90AWDTalonTSi]

I read some where that the Evo cams are upgrades to 1g stock cams-is this true? f so I can get a set really cheap. Even if its only like 5-10hp, its worth it. Or is it just a total waste of time?
Sorry, I tried a search, but came back empty handed.

Thanks-Jeremiah

There have been quite a few threads on this, surprising you didn't turn up with anything - but suffice to say, the Evo VIII cams will not work with our cars because the EVO 4G63T engine is rotated 180* compared to ours. It sucks, I know.

That doesn't hold true. Do you know which direction the engine turns? Just becuase it's mounted 180 to the 1g-2g doesn't mean anything. The engine still turns clockwise.

A more educated guess may be that the cam journals are resized. or that the cylinder head length is slightly different due to a revised valve cover, which could equate to optimized cam length. Etc.

I'm not saying it'll work, but if doesn't, it's not because it's 180 off.

Hey I was just drawing the conclusion that every other thread on the subject had come to - don't shoot the messenger I had merely meant to say that the two engines camshafts aren't compatible - the rotation being one example of the differences.

 

[my95tsi]

Actually they fit just fine. Morphius is right on his philosophy. We share the same motor as a evo 4g63 except for a few minor differences. The engines still work the same way but the evo motor is reverse. The evo cams will bolt right up and i will be getting them in soon b/c they are free.

[HokieDSM]

Well, as I said, every other thread on the subject has said that they won't fit - but if you're gonna put them in, then make sure you post your experiences! I've not read a case of them working successfully, but if they did, it'd be pretty interesting.

Please keep us informed!

 

[my95tsi]

i plan on making a tech article of it but according to my buddy who has worked on countless evo's and dsm's he said with minoir modification that will swap just fine.....

 

[smokey90gsx]

What are the cam specs?

 

[98RedGs]

What good (gains) do you get out of using those evo camshafts?

To anyone that has done this "install" or "swap" please explain.

I have no idea what the cam specs, so I can't speak to HP gains. However, they are hollow, so you've got less rotating mass which means less valvetrain loss. How much? Someone that's done it, needs to post some dyno numbers.

However, they are hollow, so you've got less rotating mass which means less valvetrain loss.

And, as a bonus - less stress on the t-belt.

I'd definitely be interested in getting some rock solid data on this. Not everyone can afford $600 for a set of shafts.

 

[99rs]

WOULD THEY FIT THE 420a????

 

[98RedGs]

WOULD THEY FIT THE 420a????

Does a 420a (neon engine) look like it would take any parts from a 4g63 engine? No.



So to answer your question which I think you know the answer to already... No.

Turn off caps lock.

 

[my95tsi]

you'd have a better chance with an srt-4 but still no

 

[my95tsi]

the only reason i wanted to get them was because they were hollow and you can't go wrong with lighter. Plus my buddy is putting HKS cams in an evo 8 and then he is going to proceed to put them in my talon so we'll see.
