325ix upgrades

Hello,
Just purchased a Metallic Blue, 90K 325ix. It is an auto, so not going to break any 0-60 records. However, is it worth the $ to do a chip, exhsust or air intake to give it a little more life? Not ready to go into the engine for camshafts etc..

Thanks
D

IMO easiest bang for bucks is decent headers (extractors) and bigger bore exhaust (say 1/2" bigger diameter). Chips can bring in their own problems and often need dyno time to optimise. Mild cam can be good next move. Please do brakes and steering B 4 any performance mods.

Thanks for the info. I know this will never be a screamer (especially with the auto). I just love the classic looks...

With or without engine mods not slowing down for corners looks fast. Do brakes first.

even on my M52 E30 i had standard brakes. nothing wrong with the E30 brakes if the fluids are kept up to date and the booster isnt leaking (very common these days to be a vacuum leak)

i would (and have several times now) be focussing money first of all on making the car manual, and then look at a good shock/spring package. stripping out the sound deading in the boot and ditching the spare wheel is also "free horsepower"

**im not sure if its easier said than done doing a manual conversion on an iX, they werent available here so have never seen one in real life let alone own one. but its a walk in the park on a RWD

Its a PITA to find the parts for a manual swap here, or so I've been told.

Chips will not require any sort of tuning; that's why you buy a chip and not a standalone engine management. Its a plug n play kinda deal, and at least on manual cars they'll make the car feel a bit quicker. However, being an auto I'm not sure anything will make it really feel fast.

My 87 325 had the 2.7 eta engine. A Dinan chip made a monster out of that car. OK, not a big monster, but from a boring car, it became one that would accelerate to 60 as fast as the E 30 M3, after all these years I still miss the red rocket.

Check with Dinan, don't take my word for it. The 2.7 in the 325e has so much torque, and it is much easier to tune than the 2.5 from the 325i. And 8.0s 0-60 isn't exactly neck breaking

Ok good point, guess I forgot that the ETA was a torque only kinda car.. What does the Dinan chip raise the rev limit to? Aren't they only able to hit like 5k stock?

With the chip, if memory serves, the limit was raised to 5300, maybe 5600. Before the chip it was a pretty lazy car, not very rev happy, I don't think it came anywhere close to 5k, but it's been so long, I traded that car in 94. What I do remember for sure was that once the chip was in, it became a whole different car. About a second and a half off the 0-60 time, gas mileage worsened -who cares-, but the throttle response was amazing at all ranges. I was told to use only premium gas, otherwise something unpleasant might happen if I revved too high.

To be honest, there is more throttle response in a mk3 2.0 then a eta. I would put my foot the the floor and it was like "Oh you want me to go faster? Let me think about that first." The car drove great but was not fast at all.

you guys must of had something wrong. as long as i was about 2500 to 3k and hit the gas, it would pull until 4500ish then of course around 118 it would hit limiter then go into oh **** going to fast mode and kill the fun

Fast is good. Stopping and cornering also has its merits.

The stock eta feels like that, yeah. A friend of mine had a GTI just like yours, put in a 2.0 16v and added some throttle goodies to it. My chipped 325 blew his doors off twice by quite a margin.

My Rabbit GTI is about as fast as a Eta. It handles better and its more fun to drive. I'm not saying a mk3 2.0 manual is fast but they have good throttle response.

They were fast for those days, no question about it. I drove my friend's GTI and loved it, looked great, sounded great, I just wasn't too much of a fwd fan. He loved my car too, we just could not believe the improvment that little chip brought, turning an average car into a real performer.

I sold Supoerchargers to Steve Dinan about 20 years ago and got the impression that he knew what he was doing
Though I firmly believe Fuel efficiency must improve when tuning a car !

Depends how you tune it... I used to have a 95 eagle talon awd turbo. Very fast fun car, except when cornering( had a buschur 50/50 locked transfer case). When I re-tuned it for the big holset turbo with dsm link, I set it up for track only, increased fuel pressure and had 800cc injectors. Trust me, 10mpg and a low 11 sec quarter mile goes hand and hand. Running about 12.6:1 on air fuel ratio.

Tuning normally Aspirated cars vs. turbo is 2 different kettle of fish.
NA can be run incredibly lean at part throttle giving you good fuel economy.
At WOT most NA vehicles run way too rich, loosing power.
But even Turbo cars can run very lean off boost
Since most of us are law abidibng citisens, we should be running at part throttle most of the time giving us excellent fuel economy. I hope that qualifies my statement ?

Any suggestions for a shop in Denver to swap a manual in place of the auto. May be too big investment. Also don't know if I should....

Thx
