MAZUR's E30 S50 Turbo - REV B

[e30polak]

What turbo and fuel?

GT35r82, but with a .63 hotside. He made the 600+whp on 100 octane. He has a 3.3L, 8.5:1 bottom end, factory rebuilt head, factory cams, factory Siemens DME tuned by Brett that used to work with TRM. He makes 400 wtq by 3100!!!! :crazy:

On 91 he makes around 550whp... ;)

Damn, a .63 hotside? T3?

Tell him to watch out because GT35's cause bent rods (according to ICS)

Well he's running Pauter Rods, so I think he's ok. ;)

And yes a 0.63. He spools quick!

While working on the car today I snapped a couple pics of one of my old pistons. The second pic shows the common porous look you get from detonation.

Awesome build Richard.

I am coming out to AZ for labor day, maybe Mitch and I can set something up, cause my buddy just finished his M50 swap, and both of our cars are sure to be the fastest things on the road.

may see if I can hook up a switch to enable WBo2 feedback. Since a wideband measures lambda, it'll hold my AFR's where I want them no matter what mixture of fuel I have at the time.

Here you go again with this stupid Autotune, you need a solid map PERIOD. Nothing can help if your maps are off.

There is no way in hell you are giving the AEM authority to modify that HUGE of a change in any given time. That is just foolish.

E85 and Gasoline are two different animals, you need to run two very different maps man.

You need a computer on hand if AEM cannot switch maps on its own.

So drama queen found his way to this thread as well?


First off, you must be only picking and choosing the phrases you want to argue without reading the whole post.

I DO NOT want to run on gasoline, BUT, I'm sure there will come a time when I'm stuck without fuel, no E85 in site, and my computer is at home. Hmm, why not just let my wideband do all the work so I can at least get home? You actually think I would boost under such a circumstance?

I don't know if you know, but the stock ECU in your car is running a fuel map trimmed by what you call "AUTOTUNE" :roll:

Can't you at least use proper terminology?

[Tchao]

Jesus Christ Richard just trying to help, no need to get all defensive.

And yes I know what I'm talking about. You do not ever give ego readings the amount of authority needed to correct the differences between e85 and gas. Period.

And for you to leave it in the ECU like that is a joke. Go post up on BFc that you will give the EMS 30% correction based solely off ego feedback.

No ecu, including stock will change a large percentage off it's programed map.

What I said is 100% true, not picking anything, without a computer on hand you must preset your ems like that day everyday....

[mazur]

And for you to leave it in the ECU like that is a joke.

O2 feedback is off for E85 buddy, which is 99% of the time.


And I'm not sure what strategy is being used by the stock ECU, but mine increased fuel by 20% when I took off the stock 02 sensor when before I was turbo. Just a point of interest.

[Tchao]

Safe map and fuel trim is different dude.
Im not here to argue man...just trying to help you out, if you don't want it just say so.

You cannot allow the ems enough authority to override your map enough to compensate for the use of gasoline on an e85 tune.

ITS ALIVE!...finally. :rolleyes :)

Started right up nicely, no goofy sounds, no leaks. Just a bunch of smoke from the mani as usual from oil hands and wrap.

Only gave it about 4 psi part throttling it for break-in (with some brake boosting as well), mostly because I didn't trust my fueling enough for WOT. My Synapse wastegate is supposed to limit me to about 5psi at its current setting and I heard it creeping open a couple times, so I'm thinking it may actually hold that number.

Also, the smell of E85 is very pleasant when burned. Sort of a sweet alcohol smell :D



Anyways, I'll to post some pics tommorrow of the final product.

the project looks great man.

im sure your aem has unused sensor inputs correct? why dont you put a switch on one, then program it as a "limp-home" map that you design for gasoline use. i havent done alot of work with aem but i would think you can put a fault value for the input that would make it switch maps.

Hmm...that may be possible with the NOS fuel map since it can be switched and I believe can have negative valued cells. I'll have to research how this map actually works. Thanks for the idea.

Alright, finally got some pics. The wrapping is that new, uber cool, lava titanium/unobtainium alloy stuff. ;) The blanket was bought on Ebay and so far I'm happy with it, although I have nothing to compare it to.



Also, I finally utilized that black, bulkhead trimming that really cleans up the engine bay from the wiring loom eye sore. Just needs a couple more simple mods to fit up better. Using a single heavy gage wire (scrap part from my E36) for the ground distribution also helped isolate wires away from the strut tower to clean things up.



So I used that wrinkle paint for the first time. The IC tube you see in the pic was my first, so it looks shitty, but the other one plus my coolant reservoir and oil cap look titties. All it takes is just another coat on top to fix it up. :)



Some may notice my brake reservoir tank placement looks like a major after-thought. Well, that's because it was. I got rid of the ABS pump in plans of having my dual MC setup done before I was finished. Well, you can see that didn't pan out and I had already shaven the bracket off to where it used to be mounted. Here's a teaser of what's to come though. (Tilton MC's and bias bar) For those who don't know where this will go, it basically replaces the stock brake booster and master cylinder setup.



A quick disconnect tee was installed for the WG signal lines. A LOT better than damn barb fittings.






So anyways, she's running well, but need to begin dialing in fuel for boost. I should have time this Sunday for that as long as I wake up early because it's been really hot out lately. My plan is to get it to a dyno once I get the fuel map down as best as I can so I can tune my spark map. Hopefully I get to that stage sooner than later.

Another note: For break-in, I secured two hard drive magnets to the sides of my oil filter reservoir in hopes of catching metal particles. For my first oil change I found a decent amount of deposits stuck to the wall. I'm going to keep them on to see if if the amount of residue that was collected repeats itself for the next oil change.

looks nice, those pneumatic fitting are so much cleaner than silicon hose and hose clamp. i replaced all my vacuum lines with them and they are way easier to work around, and holding up better. keep up the good work, maybe our cars can meet on the track soon.
