rus Posted April 20, 2013 Share Posted April 20, 2013 After almost a year since the beginning of the project I've decided to finally start a build thread. What started as a vh45 swap (still have vh swap parts if anyone is interested ) has turned into vg30 swap Here's the progress so far: Wiring is almost done, holset is mounted and downpipe is done. I'm using walbro 255 fuel pump and -8an and -6an fuel and return lines. Holset is mounted using a modified turbo relocation pipe from Acadiana sports car Still need to get a radiator, figure out how to mount alternator and how to route IC piping For now I will be using 2nd gen dsm smic that I got from a friend. Planning to run 6-8 psi until I get better injectors. More pics coming soon. Quote Link to comment Share on other sites More sharing options...
rus Posted April 21, 2013 Author Share Posted April 21, 2013 Just realized that this should probably be in the members projects forum. Can somebody move it? Quote Link to comment Share on other sites More sharing options...
rus Posted April 26, 2013 Author Share Posted April 26, 2013 Test fitted s130 radiator with taurus fan. Seems like it's a little too close to the turbo. Seems like I have 2 options: trim radiator frame and fan shroud to fit a 90 degree elbow for intake, or somehow fit radiator through the hole and tilt it forward. Also finally clocked the turbo, which was a huge pita. Quote Link to comment Share on other sites More sharing options...

Pharaohabq Posted April 29, 2013 Share Posted April 29, 2013 There's some guys doing VG30 swaps in the V6 forum on here too. it looks like yours is coming together. Quote Link to comment Share on other sites More sharing options...
rus Posted May 2, 2013 Author Share Posted May 2, 2013 Yes, it's slowly coming together. If only I had more time to work on it. Quote Link to comment Share on other sites More sharing options...
rus Posted May 2, 2013 Author Share Posted May 2, 2013 If I go with a blow through MAF setup, it'll save me a lot of time since I won't have to worry about intake piping around radiator. If I set my maf sensor on the straight pipe about 6-7 inches away from throttle body and if I thermal wrap my downpipe to prevent heat soak, would it work fine without a tune?

rus Posted May 22, 2013 Author Share Posted May 22, 2013 finishing Intercooler piping that is evo 9 IC btw Quote Link to comment Share on other sites More sharing options...
Pezhead Posted May 24, 2013 Share Posted May 24, 2013 Nice to see that the VG conversion is still alive and kicking. I started a conversion that unfortunately had to sit for quite a while (a.k.a almost 20 years). Good luck with it. I'll be interested in how you do the electrics as I couldn't get my computer to power up. I'll be posting up some info on my project some time, but unfortunately it's a long distance and long time love affair. My Z is at my mom's place in Seattle and I now live in Sydney Aus. Only make it back to the US once a year, max so it is back on hold for quite some time Quote Link to comment Share on other sites More sharing options...
rus Posted May 24, 2013 Author Share Posted May 24, 2013 Yeah I'm too deep into it to quit now, It's been almost year now. Wiring was probably the most difficult part of this project but it seems to be working. You just have to follow the diagram. All you really need is s30 wiring diagram, z31 ignition and charging system diagram and vg30et ECU pinout. Good luck with your project, it'll be worth it in the end.

rus Posted May 24, 2013 Author Share Posted May 24, 2013 Will probably have to change some of the piping later to make it more efficient but this should work for now. Quote Link to comment Share on other sites More sharing options...
rus Posted June 1, 2013 Author Share Posted June 1, 2013 Managed to get it running today. Runs a bit rough but should run better when I fix all the vacuum lines. Only problem so far is sometimes it hesitates when I open the throttle and sometimes dies after I close it. Also found out my FPR is bad. Running open downpipe Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted June 1, 2013 Share Posted June 1, 2013 Congrats. That rough running is from being too rich from the vacuum leaks and un-tuned state, as well as the FPR, like you said. Runs way better than my broke, low-compression VG. Looks like your engine is the same position as mine. What kind of mounts do you have?

But hey at least your car is complete and drivable and there are lots of VGs at junkyards. I still have a lot of work to do just to be able to drive it. Engine should be in about the same position since we both used stock mounts to mount it. Basically I just have 2 brackets that connect stock engine mounts to mounts on cross member. I'm still trying to find a drive shaft that would fit my car since my stock 5 speed shaft was too long. Transmission is 25.3 inches away from differential.

78zstyle Posted June 1, 2013 Share Posted June 1, 2013 I think if SOMEONE (HINT HINT) would make a swap kit, this swap would be way more popular. Quote Link to comment Share on other sites More sharing options...

Transmission is 25.3 inches away from differential. I used the 280Z 4 speed driveshaft with the VG's Nissan 71C transmission. I also used the 280Z transmission crossmember (although I had to swap the isolator or something, can't remember, but it was bolt on).

Haha I wouldn't have time nor resources for that.. Plus where is the fun in a bolt on swap kit that doesn't require any serious work?? I used the 280Z 4 speed driveshaft with the VG's Nissan 71C transmission. I also used the 280Z transmission crossmember (although I had to swap the isolator or something, can't remember, but it was bolt on). Hm I'm using the same transmission with stock 280z crossmember. I guess I need to find a 4 speed driveshaft. Either that or pay $300 for a custom one. Quote Link to comment Share on other sites More sharing options...
rus Posted June 3, 2013 Author Share Posted June 3, 2013 Does anyone know if I have to use original z31 turbo fpr or would any vg30 fpr work? Or are there any other options for a junkyard FPR? Quote Link to comment Share on other sites More sharing options...
Pezhead Posted June 3, 2013 Share Posted June 3, 2013 Check AutoZone. I thought Mine was missing so ordered it from them. It wasn't very expensive. I ended up returning mine as it was still on the front of the motor. Quote Link to comment Share on other sites More sharing options...
