Intake system?

^^ yep, that will also add power.

[Bimmerman325i]

best way to add power is ditch the B27 and get something with a "LS1" or "S54" in it.

fixed that for you.

best way to add power is ditch the B27 and get something with a "50" or "52" in it.

I ran a jim c chip for the past 8 months on my 173 with full 2.5" exhaust and s3.73 and wasnt super impressed. Throttle felt more on/off and didn't pull much harder imo. Then again I have no cam or intake. Went back to the stock chip and 89 octane and actually like driving it better. Plus, i've heard things about valve float on chipped cars without a cam. If anyone wants a 173 chip, $120 shipped.

I agree, I just find it funny that people talk about the E30 as if it is engineered so well that nothing will do anything for it. They may not make a ton of power, but if BMW had made the ulitmate eninge it would make more power.

[iamsam]

a CAI on an E30 is rarely a benefit, the E30 has a pretty efficient air box. GRM did a test where they lost 5 hp when they ditched the stock box for a cone filter and no heat shield. With a really good heat shield and proper air routing, it is possible that a cone filter may help.

Don't bother, you will lose power. It is well documented, search for it.

Tune up, chip and a 3.73 LSD will transform your car. Don't waste money on useless crap. No one on Ebay knows as much as the guys in Germany.

Obviously not, but everyone talks about BMW as if they made the most absolutely perfect engine. They had to make some compromises. If the design is so great, wouldn't the engines make a lot more than 168hp from the factory?

"6" is my guess

[devon.818]

I've wrapped it past 6 the other day

uhm?
if its an e there is no 6?

my eta is chipped, i redline it and it pulls still while redlining.
luke, you really selling that diff for 100$?
i'll take it.

[Bene]

does it have the i throttle body and intake setup or is that all e?

anyone have pics of a stock e and i engine bays?

[StereoInstaller1]

I have seen 3.73s in good condition sell for as little as $100 and as much as $500.

How do you know for damn sure your car is shipped? "PO said so" never ever cuts it with me.

How high can you spin your motor?

[blue325es]

Well making plans for my next paycheck.. Haha how much is a diff?

[devon.818]

Well I was told it's got a dinan chip.. ( I have the dirty exhaust car from boulder if you remember it from CL) I welded a new exhaust but was stupid and didn't get a high flow cat:/ just tryin to get a little more power out of it. Thinking of a comforti chip instead? Ive seen the high beam delete and I don't think it looks right. I dunno.. Any ideas? An 3.73 LSD is a little out of the budget right now:/

best bang for the buck is a chip, but you already have one....i'd say do maintenance, seafoam the engine, highflow cat is a must.

you dont have to delete a highbeam, you can do run hosing anywhere...
new diff will DRAMATICLY make a difference.

what is your budget?
