e30 turbo?

[quertreiber]

FLG Tell me why you would advise someone to disconnect a vital sensor to somehow increase HP?

Well. Obviously you never really played around with E30s. On newer cars I would agree. On the E30 is an easy way to make some HP. All the O2 sensor does is check the mixture. Nothing else. You disconnect the sensor and the Motronic goes to default in the mixture. It will keep the normal ignition and timing tables. All it does it takes the rpm signal, throttle signal and AFM signal and uses this information for the fuel injection. And to be on the safe side the Motronic will make the engine run a bit rich. This is where the HP increase comes into play. Yes, your fuel mileage will go up as always if you want more power. I'm running my E30s now for years without the O2 sensor. No problem at all. In Germany they don't even have a check engine light for that.
Cheers! :D

OP you sound like a young guy that has a lot to learn but doesn't know it. We all were there once before.
Do a bit of reading on e30tech. There is some good info on there. Not like the bullshit we have on here. I can't be fucked pointing my finger at anyone at the moment. Just dont be influenced by their false information. And don't agree with the things you want to hear. I'm just telling it to you straight out. If you want a reliable kit spend the money, if you want to redo everything then go ahead and buy an eBay kit with an rrfpr and ebay turbo chip. For $1500 more you can piece yourself a setup that will give you less headaches and perform better.
I work in this industry and I know what works and what doesn't. My last motor I built made a 1025hp. That was a sohc Nissan rb30et. I have also had to redo peoples turbo setups because their Chinese kits have been giving them grief. If your not on a tight budget why not just do it once.
Like I have mentioned earlier I have been in a turbo m20 with an eBay kit. It was quick but nowhere what I expect from a tough turbo 6 cylinder. Infact I'm making that owner another turbo manifold because his Chinese one leaks exhaust gases too much. Like they say the poor man pays twice.

e30tech has a lot of good info. Its technical, not fuh raze. lol

I really wanted to go turbo. I added everything up and decided to put it off for a little bit. If I turbo my car I want to do it right... rebuilding and balancing my bottom end, all arp hardware, oring'ing the head, welding the head, decking the head. twinscroll, twin tials, ebc, standalone ecu, etc.

I added things up and it looked like I would be spending about 6k. I decided to put some of that money towards other things. I am young too, and I haven't driven the e30 that much as it has been apart... I am now planning on spending some of that on a cage and track time. I have never even tracked my car, so how can I judge it without fully pushing it? the track is way more badass then speeding around on the street like an idiot and most people that track e30s have N/A m20s...

I agree with quertreiber it really isn't worth spending money on these engines unless you go forced induction. These aren't v8's where porting the heads running a hotter cam will give good gains.
But I don't like the ebay kits. The turbos they provide are too small, poor quality and they sound funny :p
Manifolds are crap there is no other way to describe it.
Intercooler kits are ok. Not great but not terrible either.
You can piece up a better kit yourself for a little bit more money. Just be patient, look for the deals, know what your buying and get your motor tuned correctly.
Begi fmu and turbo chip isn't a good way of tuning, its for tightarses that don't understand how crucial this part of turbocharging your car is. You may get fueling right but your best also setting up a good timing map, if you want to make good power and have your engine last a long time.
Thats where a standalone ecu comes in, you can gain full control of your engine management system. Blueapplesoda and whodwho have made it easy for us with their plug'n'play megasquirt kits.

One of those ricer mods.
Swiss cheese the airbox.
Use hose clamp on fuel return line for more pressure
Cannon muffler ect.

Well. I'm all for a build that costs you thousands of dollars. Sweet. If you don't have that kinda money and still wanna go fast you have to figure out a way to do so. Thats where the ebay kit comes in. And to be honest I'm running an ebay kit now on the 4th E30. All of them worked out well. Considering how many problems you see on this website or e30tech where people build stuff for a lot of money and can't get it to run I think the my ebay kit is doin pretty good.
Back to kamakaasneal. If you don't have the money for a turbo build or other quality bolt ons don't do anything and save your money. I think bolt ons like cams on an M20 is a waste of money. Get a nice sounding exhaust and disconnect you O2 sensor and call it a day. Cheap power.

[Hey_You]

well if you can do the right things to it yes...and yeah i plan on keeping it for as many years as possible but i cant keep it as my ONLY car..kinda impracticle...im just trying to get as much fun out of it as i can b4 moving on...plus i get good pay so i can afford both a really nice e30 and a newer car..without much compromise so i figure why not do both?

Then yes, cams and basic bolt-ons would be your best bet. Maybe build a 2.7i if you wanted a little more and have it drop right in

[kamakaasneal]

well i AM on a tight budget cuz i just work odd jobs...get roughly $130-$180 a week depending on what i do so i don't make enough money to truly get most of what i really want...the tint on my front lights was pulled off of my rear windows and x-acto knifed onto the lights and all the custom paint on it i bought spray cans at auto zone and used them...the only money ive spent directly on the car so far was on the $7 piece that fits in the back of the steering wheel and completes the circuit to the horn...everything else was something i did on my own. luckily my dad (who has almost 45 years of experience working on cars and trucks, and is a nuclear physicist) is there to walk me through most of the stuff xP so yeah, money isn't my strong point currently as far as funding a super awesome e30 sleeper goes, i can just do what i can to make it start :P so i'm looking for cheap power...but thanks, id hate to put on a turbo and have it backfire...i'll put that money to other use :) maybe...cams ;)

This is actually relatively easy. Get that kit. Oring the block (if in budget). Get arp head studs and factory head gasket (lot of opinions there) get a fmu and some 21-24lb injectors. Get a turbo chip (have to make sure you have the correct dme) get your boost,a/f and oil pressure gauges and have fun. You can spend lots or a little. My build was prob around 2g with me doing a lot of fab and all install work(plus running car) and last night I had a lot of fun in it. I'm running 15 psi and have that feeling like there's nothing faster, course there is but for total investment of around $3500 it puts a big smile on this face.

ok, you make it seem easier...haha thanks...yeah this should be 12 psi but i might be able to increase it o.O thanks dudes :)

[quertreiber]

Look at my build. I have my turbo build in the project garage posted.

[quertreiber]

Yeah. It's pretty straight forward. Low boost setup is reliable. I bought the same ebay turbo kit. Needs some fabrication but I can tell you with an E30 Turbo you will beat that Z4 and the bitches will be trippin!

[The Humjet]

I tell you what I was really surprised when I first took my mates m30b35 swapped e30 for a drive. So much low down torque if you just like to take off the lights quickly and give people a run its a good cheap option. There are a lot of guys out there that we pissed off when we blew the doors off their cars at the lights. I have also been in a low boosted m20 they are both very close I couldn't pick which one was faster. For an inexperienced driver (no offense) your better off putting in an m30 just because powerband is so broad it won't catch you off guard.
For a couple thousand dollers you can put in an m30 that you could rely on to take you to work everyday and run a low 14 second/ high 13 second pass.

[Hey_You]

If you make good money, buy good parts and do the build right? Megasquirt, Holset, and the other supporting items and be done with it. Or better yet, a DMS Kit!
