thiazole great turbo trade

[ricehunter]

Just wanted to thank thiazole for the great turbo trade, I'me very happy with it :D just need hard pipes now

[prophecymiller]

Any report on how it's running? Did you get your problems sorted out? What psi are you running it at? I can't remember, but do you have stock injectors or any fuel compensation? What rpm does it hit full boost and what rpm does it hit max torque? Just wondering...

[ricehunter]

Umm torque I have no Idea, haven't dynoed it yet, but it hits full boost at a little over 3k @ 15 PSI but I know I need to get a diffrent BOV. BTW I'll have the type R soon (pending UPS) which Hopefully i can trade for a type S/RS w/recirculation

Edit: almost forgot, stock fuel system, I'm gonna hunt down some 750's + and proably borrow my bro's AFC if he'll let me until I can get DSM link (hopefully Santa will get it for me :D)

[Wazzelby]

Which turbo did you get from Bob? The T28 or the 16G?

[ricehunter]

t28 traded it for my suround sound system, man Im gonna miss that thing, but I'm happy :D I had to lossen the pree load so I didn't hit fuel cut =\ that would be bad...

[prophecymiller]

What kind of exhaust are you running? I'm not sure but 15 psi is a little high I would think for a stock setup...Maybe 12 would be more safe and should still make more power than before.

[ricehunter]

Well, I'm running a stock O2 to a 2.5" DP that transfers to a 3" exhaust, I was going to do a full 3" but the flandge after the cats didn't match up. I swapped out the BOV for a GReddy type-S and hopefully a hardpipe & FMIC setup.

Did you mean it may be too much for my stock fuel setup? Thought I would be safe @ 15psi untill i upgrade to the 750's & walbro 255 w/afc

[prophecymiller]

I'm not really sure the airflow vs. fuel flow numbers, so somebody who is more knowledgeable about the math can chime in here, but I think I remember that I was starting to hit 100% duty cycle on my 450's at 14 psi on the same turbo according to dsmlink...you could look it up with an engine math calculator online.

I'm enjoying your surround sound system as well. I have Netflix and a theatre room with a DVD projector (can you say 12 foot screen?). The only thing missing was a decent surround sound system.

As far as your injectors go, you can probably handle 14psi, but don't go any higher than that until you get your injectors/fuel pump upgraded. You should really log it to make sure, though. I was pushing the limits of my 750s on E85 which is probably similar to running 550s on gasoline. The problem isn't maxing out the absolute flow of the injectors, but maxing out the injector pulsewidth at lower rpms because that turbo makes so much low end power.

I'd be interested to know how those 750's run with an afc. I'm debating going larger than the 550's I've got now, but didn't think anything that large was a good idea with just an afc. Or are you thinking you'll just live with it until you get the Link?

[ricehunter]

Glad it is being put to good use, it wasn't being used with the last month (scene I sold my xbox)

Well I may do 660's with an AFC then upgrade to 8-somethings with the link so I can properly run e85, and hopefully I'll have a hot-wired 255 in there by then.

I ran 660s that flowed more like 720s with an AFC and a B16g. It wasn't fun. I had a hard time keeping knock at bay because I was fooling the ecu into such a high timing map. I ended up having to run WI to run any decent boost and it still never really ran very well. Having control over timing goes a long way to having a car that runs well. A 2g *might* not be as bad as the maps aren't as aggressive as a 1g. Then again, with the higher compression, it might be just as bad.

[thiazole]

Can you pull back the base timing a few degrees to help compensate? Also, I thought the 2g had less compression...

When you're ready to do the hotwire, let me know and I can help you out if you want/need it.... I did Quinn's back in the day and I haven't heard him complain (about it... we all know he complains!) since then ;)

Plus I have a mess of tools (the few that are portable) for electrical stuff that never get used anymore ;)

[XakEp]

Hurrrrrr

At least you did a good job and didnt cut the wire anywhere near the wire connectors on the ECU.

[ricehunter]

That would be awsome :D now all i need is the 100 for the fuel pump...Craigslist in my friend

[yokotabrat]

Sure, although I thought the base timing wasn't adjustable on certain 2gs unless you swapped to a 1g cas? Don't know for sure on that one. In my case, I was running timing advance in the range of 30+ degrees. Compare that to 10-12 degrees when I started doing my own chips. Pulling 15-20 degrees out of base timing would probably make the car run really bad at everything other than WOT. :D

2gs definitely have higher compression stock. 8.5:1 vs 7.8:1 on a 1g.

Yah fixing that crap SUCKED! I forgot about that... I did resolder those PITA's right?

Don't need a new pump to do the hotwire mod ;) Just need the upgraded wire size and the connectors... new pump will connect to it just like the old one did :D

[XakEp]

I think so. If not you're more than welcome to.

[thiazole]

Oh yeah, that's right. For some reason I was thinking a 1g had 9:1.

[ktiedt]

Heh, I vaguely remember laying upside down their soldering and retaping the lines, heat shrink would be a good upgrade though :p

[XakEp]

Heh, I dunno if a safety repair counts as an upgrade. Considering how the rest of the car is, hrmmm...
