I was planning on testing the car up by you @ ubly. I could easily get 10 passes within 3 hours there. Much better than waiting for 20 minutes to get to the line at milan.

Well I drove the car today, It feels ok = needs more boost. Right now I have the boost set at a steady 8psi, but creeps to about 10 under WOT while the VCT is working. I couldnt get the tach working however. Which sucks but oh well. I think I will be upgrading the car most of the summer with little things. The butt dyno reads about 250-300whp. I will get a baseling soon to see exactly what it is. The engine pulls hard through all the gears. The complete exhaust and IC pipes cost me $320. The IC pipes are stainless and the turbo back is aluminized. I have the magnaflow 14834 stainless muffler mounted out back. The bad; I need to take the tranny apart and measure the end play for 5th gear, under power it makes noise. No biggie parts are readily available and easy to get ahold of. Pics and exhaust clip.

HOLY CRAP!!! Very nice numbers! When I get my car back from the exhaust shop we should terrorize some mullets!

Freakin sweet! Moving along really FAST!

Well I finally got my car out of the garage, only to find that one of the o-rings on the AN fittings is bad. It drips once every few minutes. The radiator hoses are done and in also, waiting for the filler neck. I have all of the parts to finish it up on the way, then off to the exhaust shop for everything else. I have the 3ZR- 1 springs installed also. Pics... Me with the car...

Damn, I had no Idea that there was someone from Bad Axe on here. Lol I have a place in Harbor beach, On shock rd. Next time I am up there we should meet up. I will be up there with my Z in the next few weeks. Nice looking set you got there, and a great price! Mine cost me about 2700 shipped to my door.

I did a little work to her tonight. I have the radiator installed and the new shocks in the rears done. I will have the fronts on and installed tomarrow night. I should have it on the ground and in the driveway by this weekend. Pics...

Do you ever get that feeling that you have just conquered the world when it is just a small task? That is how I felt when this happened... That was the first startup of my rb25det in the 88 300zx. Now its time to get it back together... 2nd Startup...

Did a little work this past weekend on the car. I put the driveshaft in, put the tranny mount in, installed the full wiring harness, hooked up the oil cooler and a few other odds and ends. So far I dont think that the driveline angle is perfect, so I will fab up a new tranny mount. But the angle it is at right now is acceptable for test runs, and initial shakedowns.

Well as of yet, I havent even finished my RB build. As soon as I finish the RB build I will start the VG build. I am about a month away from driving the RB car, as long as there arent any hiccups. I dont plan on having the comparison sheets complete for at least a year. A lot of the same parts will be on both cars also. I just picked up a whole slew of poly parts and new race springs for the RB car, should be installed in about a week. Once I am back in Michigan permanently things should start happening very fast. Thanks for the compliments on the car, it keeps me motivated.

The rb speedos are the same as Z31 and Z32 trannies. rb20=z31 rb25/26=z32.

So I got to work on the car and mocked up the radiator and fmic. I am sure that the radiator will be moved more forward and the fmic will be moved wherever. I also located the oil filter block and am waiting for the cooler. The drive shaft with out the rear flange measures 25 3/8" which is being made this week. I plan on wiring up the car tomarrow, but who knows what else I will get done. Pics...

I Have a series 1 rb25det, and it has both holes drilled. I used the same method as above, however I had to bend the dipstick tube a little to be easily grabbed to check the oil level.

Well the wrecked 84 turbo runs great, the 86 turbo has the engine removed and the rb25det 88z31 isnt running yet, I have to wire it and run the fmic piping and a few other things and she will be ready.

I knew I could find an example for a guage swap. He can make one for you. He has turn signals and everything. His screen name is zmech on http://www.redz31.com/forum/

1/15/07 Well I have been looking for the 10mm fittings for the slave master for 2 weeks now and I am at my witts end, no auto parts stores carry the ones I need. I have had a parts guru looking with me, to no sucess. But I finished the crossmember and installed the new rack, rack bushings and tie rods. Once I get the fully treaded 10mm line nuts I can final install the rb and get her running. Pics... 1/21/07 OK i got back to work on the car today, but didnt get much done. I found the 10mm line nuts that I needed at the local dealership. So I then made the new clutch line from the master directly to the flex line on the slave. Pic... Tomarrow I plan on setting the engine for the final time along with the tranny. Updates will come regularly and more frequently in the next few weeks. I final mounted the RB last weekend, and installed the new poly mounts thanks to Jason @ Z31parts. I also installed a unsprung Nismo clutch disc and heavy duty pressure plate. I got a new vertical mount radiator and electric fans to install later. I also bought some new wheels and tires. Rears are 18x10 et 22 with yokohama AVS sports 275/35R18 and fronts 18x9 et 24 and I am thinking of going with either falken azenis 245/40R18 or cooper 2XS, not too sure yet, right now the fronts have 275/35R18 toyo proxes T1-S and fit perfect. I will probably have to roll the rear fenders a little to be sure that I dont cut a tire. Anyhow pics....

10/14/06 So I got everything bolted up on the Z, The crossmember bolts directly in now. It went pretty smoothly only a little bit of prybar action. The turbo elbow has more than a half inch clearance between the heat shield and the steering shaft. I did encounter a clearance issue with the speedo sensor on the passenger side, I will bring home the air hammer soon to fix this issue. I also had an issue with the tranny mount bolts, they were too wide so I ground the head down to the bolt itself. Now I am wondering if the driveline angle is correct. I guess I will have to bring home a magentic angle guage. Here are the pics... 11/25/06 Sorry it has been so long for an update but I have been very busy with the house weddings and wiring. So I got rid of the greddy fmic for a brand new treadstone/spearco fmic. The main reason for getting rid of the greddy is because it was used, and I sold it for way more that I paid for it. Next I swapped the auto pedals for a clutch and small brake pedal. This took all together like 20 minutes, very easy to change over. I am on final mock up and am removing the engine tranny tomarrow to do all of the final welding. Then I put her all together and start the power steering mock up and remote oil filter and cooler. I will be sending the car out then for the FMIC piping and then she should be running. Pics Updates should be coming more often now, Likely every weekend. 11/29/06 Here is a couple pics of the modified crossmember. Right now it is just tacked together, tomarrow I should have it done. 12/10/06 Sorry for not updating sooner, I have a lot to do in the next few weeks. well, the crossmember is finished, and I got a slew of new parts. I got the turbo calipers, hubs, rotors, new rack, new tie rods, new rack bushings and a few other things. I will be ordering Jason's poly mounts very soon also. Unfortunately I wont be able to use the tranny mount that he makes. I also made an interesting discovery about the shortage of turbo calipers. The 1995 infinity J30 calipers and mounts will bolt up and have larger pistons by 1/4" each. Well here are some pics.

10/07/06 As Dramier suggested I cut the core support/ hood latch out to get the engine/trans assembly into the car. I plan on making some brackets to weld onto the removable hood latch portion, so that the timing belt will be easy to access instead of removing the whole engine. I finally dropped the whole assembly into the car, and wouldnt you know, I dont need to modify the tranny tunnel at all. But on the downside, I do have to make a bracket to mount the tranny to the trans crossmember, this should be butter to do. Z31 tranny mount on left, RB tranny mount on the right Z31 tranny mount on top, RB tranny mount on the bottom The shifter lines up perfectly in the old automatic hole in the tunnel. There is about 1/4 inch clearance between the steering shaft and the turbo elbow/downpipe. And there is plenty of clearance under the hood. 10/09/06 I made up some brackets for the tranny today. I havent gotten around to putting it in yet, but I am 85% sure it will work with no problems.

8/10/06 I got some new parts yesterday. The 200zr oil pan and pickup. I put them on after relocating the dipstick tube. I will have to straighten out the tube because the dipstick will not go in or out smoothly. It is quite hard to find a reasonable place for the tube, the coolant-oil cooler is really in the way. I also recieved my guages that I will be using temporarily until i get the chance to make everything for the aftermarket guages. The plug for the dipstick tube is easily removed from the inside of the engine. To install it into the front location i set the plug into the hole and tapped lightly onto it setting it in place. I then grabbed a 1/4in extension and set it into the proper place. Here are a few pics... **edit** FYI http://www.nismoparts.com/catalog/?section=756 is now carrying N1 water pumps, N1 oil pumps, exhaust manifold gaskets, timing belts, idler pulleys and tensioners. The tensioners are the same as VG30's though. 8/13/06 So I did a test fit today... So far the issues are that I would like to have te engine sit down in the cradle about 2 inches further lowering the CG. I think I will cut the existing crossmember down. I also need to change the angle of the engine mounting pates that I made by about 10-15 degrees, this can be done when I cut the crossmember brackets. I will need to make a powersteering hose to run to the rack, and mount the resivior on the US drivers side. There is pretty good clearance all around the engine other than that, I think that A/C could easily be used if I wanted. Well if you have any questions or suggestions please leave me a message. Here are the pics. 9/16/06 Ok so I finally cut the engine mounts for the RBZ31, Now I am waiting for the harness (two weeks). I plan on welding up the new mounts tomarrow, well as long as the test fit is good. Then I will move on to the transmission fitment. Enough talk here is a pic of what I did today. 9/24/06 I did a test fit today, and it looks pretty good so far. I need to bolt up the tranny for final fitment. Aslo there is going to be a revision in the mounting plates that I made. They are going to be an inch longer and the bolts are no longer going to be staggered. like this... So here are some pics of what I got done today... There are just a couple of interference issues so far, most notably the power steering lines to the rack. The other is the steering shaft it clears but not by enough yet... Another issue is the ride height, right now with just the rb in there it seems way too high, seeing as to how much the tranny weighs it will still sit a little higher than factory. No biggie, I plan on getting coilovers anyhow.

another thing I forgot to ask is.... Do you have a digital dash? If so you still can use the guage. You would need the longer speedo cable though and re-locate the vss located on the shock tower.

7/23/06 I don't know what got into me lately, but I now have the engine on a stand, the car is being stripped of all the engine bay rust and I am getting all the measurements done for setting it in there. This engine will be a very tight squeeze as the engine alone is about 30 inches and the measurement from the firewall to the core support is 31.5 inches. This should be fun. I plan on cutting the core support out and making some brackets to bake it a bolt in core support like the dodge intrepids are. Well here are some pics.... I am not done removing all of the rust in the primered areas, it started to rain. 7/26/06 Yet another update on my swap. OK, so I took some more measurements today... What I need to do to get the RB to sit in the engine bay... I need to swap the two engine mount brackets on the crossmember so that it moves them in 2" each. 18" 22" The factory engine isloators form the VG bolt on to the RB, so I can use the poly mounts. The only difference between the isloators is the diameter and the length of the stud going through to the engine mount bracket. Well I guess that the two studs is a difference too, but That is only on one side. RB isolator VG isolator Also the distance between the tranny and engine mounts are identical between the RB and the VG at 39.5". Factory tranny mounts will be used. Now I am waiting for the 200ZR rear sump oil pan and pickup. By the time they get here I should have the mounts swapped. So it will also be test fit time!!!! 7/28/06 I'll get around to the engine bay measurements later. Right now I have a bunch of sand stuck to me form sandblasting 90% of the rust out of the engine bay. Pic... 7/29/06 Measurements of the engine bay and the RB engine itself. I think I will not be moving the existing mounts on the crossmember... Instead I am thinking of making this out of 1/4" steel plate...(for mockup) then reinforcing it. Any suggestions? (besides being in actual scale)

Was your z31 a turbo?

I am updating this thread over in the member's project thread form now on. Here is the new link. http://forums.hybridz.org/showthread.php?p=736735#post736735.

Here is a link to what I have done already, I will be posting all of my updates in this thread as it seems appropriate. http://forums.hybridz.org/showthread.php?t=109458. Please post any comments there. I will be adding everything (pics) into this thread as time permits. 4/30/06 Started removal of parts today. now she will sit in the air for a few months...Started taking apart the old Z31 VG30E, before I started and about to get dark outside so I quit here. Total lapse time about 45 minutes. The radiator is just sittin there, cuz I am going to start the engine tomarrow and change the oil for whomever buys it. I plan on taking video of the engine running. 5/02/06 After another day, the engine is ready to come out. 5/22/06 Well got the engine out today, As I decided to go out and party yesterday. It was really easy just forgot to take off the crank pulley at first. The new home for the RB25DET!!! 7/20/06 OK so I actually started to work on the car again... Right now I am flipping the engine mounts on the crossmember, Putting a new clutch and all new timing parts. While I am at it I am going through the turbo because I found a MAF screen and plactic in the intake piping. I am first cleaning out the garage though. Here are a few pics of the ride and engine(s).... A couple more pics... The timing belt appears to be unworn/unstretched. Thus confirming the 20k miles that the importer showed on the video.

Arent the cams for the european Z31's different? I remember hearing this a long time ago, just confirming.
