Cam Upgrade

[Andy.B]

I guess both...

The I intake manifold is different, with larger ports, and should be swapped in at the same time as an 885 I head.

And I would also recommend a compete I exhaust, including the exhaust manifolds, cat assembly, and muffler. It will flow better and sound better than the e single pipe exhaust.


Edit: I see what you're asking about. If you stick with the eta and decide to go with the chip/diff/exhaust route, I would go with the I exhaust manifolds/cat/muffler.

So any e30 I car will have these? I will definitely snag the headers and exhaust. I may also grab the diff while I'm at it. I am also snagging a shifter out of a Z3.

I may go ahead and snag the I head too, I have ported and polished a lot of heads. I would just simply clean the castings up wouldn't remove any material because on paper those heads look pretty good.

But this is a maybe, I will prob just do the easy stuff this year because I want to get rid of all the gremlins and paint it in the spring. Diff, exhaust, intake, chip, from what your saying I would prob be happy with that.

The diff you want for to upgrade an eta is actually out of an e28 5 series. 325i's have 3.73 diff's which are too tall for an eta.

[Bullhead]

The e28 is the car that looks like our e30's but bigger right? It has the round headlamps etc...

Well shucks all they have is a 1983 5 series so I won't be nabbing one of those lol.

be wary of using an I intake manifold on the 200 head the step down will be nasty. id only swap manifold etc if the head gets done to

Roger that. I have decoded to just do exhaust, chip and a K&N filter and grab a better rear diff.
