BLOZ UP Posted October 2, 2013 Author Share Posted October 2, 2013 (edited) Tired of being thrown around on autocrosses is more like it. Also, barely fit with my helmet on in the stock seats. I'm hoping I can get whatever seat I get lower than it is right now. Edited October 2, 2013 by BLOZ UP Quote Link to comment Share on other sites More sharing options...

BLOZ UP Posted October 13, 2013 Author Share Posted October 13, 2013 Took apart VG33, going to see if I can get it to the machine shop tomorrow to clean it up. Checked main bearing clearances and bores. Looks legit. Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted October 24, 2013 Author Share Posted October 24, 2013 Reviewed datalogs and smoothed out area at and around 220kPa @ 3000 RPMs (17psi). Turns out in 4th and 5th gear I get full boost (17psi) at 3000 RPMs. Nice. Getting close to the surge limit of the compressor (according to my spread sheet calculations), but some cams and head work should increase the margin a bit. Oh, and switching to the 3.3L will definitely help as well, which I can hopefully have done by next season. Got new Hawk pads on. Will bed them in this weekend and give them a try.

78zstyle Posted October 25, 2013 Share Posted October 25, 2013 Man, going to a six cylinder will be a real nice upgrade. Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted October 25, 2013 Author Share Posted October 25, 2013 Yeah, from my 5.5 cylinder. For real though, +0.3L, 10%. Should mean I get 10% more power. Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted October 28, 2013 Author Share Posted October 28, 2013 I'm having trouble at low rpm and high boost. Lots of shuddering. Pretty nasty feeling. Feels like it's misfiring. Double checked and redid my flow calculations and I should not be surging, or even close to surging. Not sure what's going on. Spark blowout? Bedded and tried out the new pads. Seems to bite a lot better. Painted the VG33 block. Need pistons. Quote Link to comment Share on other sites More sharing options...

It actually ran pretty good at WOT.. Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted October 29, 2013 Author Share Posted October 29, 2013 How broken? Maybe that's it. I've been beating the crap out of this thing. Quote Link to comment Share on other sites More sharing options...
78zstyle Posted October 29, 2013 Share Posted October 29, 2013 (edited) When I disassembled the engine, the piston came out with zero resistance, the skirts were broken on both sides. Rings were kaput too. Edited October 29, 2013 by 78zstyle Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted November 12, 2013 Author Share Posted November 12, 2013 (edited) Fixed spark blowout/misfire issue. key was 0.030" on all cylinders except #5, which is at 0.040" (pretty much stock). Runs like a champ now. Hard to start, but that's this crappy compression. I also pulled a couple degrees right at peak boost at 3000 RPM for good measure, and interpolated a few lines around it. I was going to creep the boost up to the 20-22psi range to dial in the fuel table there, but I think I'll scrap that since the tune is good enough to try on the VG33, and it hasn't blown up. I'd like to not break stuff I might need when swapping to the VG33. Plus, winter is coming. Edited January 20, 2014 by BLOZ UP Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted January 13, 2014 Author Share Posted January 13, 2014 (edited) Started it and warmed it up. Missing on one or two cylinders until warmed. Next autox is in early April, so it's time to finish my VG33 rebuild. Edited January 13, 2014 by BLOZ UP Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted January 17, 2014 Author Share Posted January 17, 2014 (edited) I'm going to get started on the motor swap soon. I will see if I can pull the old motor this weekend. Only thing I know of is an exhaust leak on the driver's side. I've had this before--it might be the flange has warped. I can get that resurfaced and it's not something I'm worried about. I'm using silicone gasket so that's the main problem. It only leaks when cold, suggesting that there may be some warping as temperatures change. I will split the flange in between the primaries and remachine if necessary. I'm replacing the VG30 with a VG33 and will be taking them off, checking them out, and getting them coated. Also, the free picture hosting I used went under, surprise surprise, so I'd have to find the photos from this thread again.

BLOZ UP Posted January 20, 2014 Author Share Posted January 20, 2014 I did a final compression check before dissassembly: 1, 2, 3, 4, 5, 6 (PSI): 161, 185, 161, 185, 80, 185 So, not horrendous, but the passenger side bank is pretty weak. Could be a headgasket, although the coolant and oil stay clean. It does eat oil quite fast, and there's coolant on one of the plugs, oil on another. The driver's side is also suspiciously high. Regardless, the motor is coming out. Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted January 22, 2014 Author Share Posted January 22, 2014 (edited) I tried my hand at polishing the crank. Good god I was nervous about screwing up the surfaces. I used 400 grit just briefly, since I really just wanted to get some month old surface rust off. Ended up working really well--looks spiffy again. Honed the cylinders. My hone is apparently a little on the rough side. Cross hatching is, uh--a bit pronounced. I used a shitload of oil but oh well, there ain't no glaze anymore. Cleaned the bores. It's the god damned Exxon Valdez on the garage floor now. Installed main bearings and crankshaft on the VG33. I did manage to dent the #1 top bearing--just a tad. I dropped another bearing which hit it with the corner. Ugh. Don't think it's a big deal, but now I'm paranoid. Well, not paranoid enough to order another bearing. I figure if this engine spins a bearing--any bearing--I'll blame it on that. Maybe I should refrain from rebuilding motors when it's butt **** freezing in the garage.
