Just another SR20DET 240Z build... not 56k friendly (if that still exists)

Recommended Posts

As far as tuning systems goes, anything can be learned and tuned, but why be the car someone learns on? The AEM will give more accurate tuning RPM band wise, some more features, and be a self contained unit.

Not sure where you got your statement from but Aem is 16x16 maps IIRC

Haltech has had 32x32 maps since the e8. I have it on my Z. If a tuner can tune AEM, then can tune a haltech.

 

 


Also, AEM has had NOTHING but problems reading the Nissan Factory CAS. You even have to install their own disc in. Haltech reads the factory disc.

Haltech is a better system. I would even take an out dated E8 over a series 2 AEM

I like Haltech, I was just thinking I would try AEM EMS2 this time around. The Haltech Sport 1000 is the closest comparable price wise to the AEM EMS2 and is on my list to look at when I get closer to placing an order. I was planning to use the AEM disc, but using factory might be nice. The price difference is negligible, but I would be dealing with the patch loom again (I think). The AEM 17x21 (LoadxRPM 3D) map size is actually good from what I have seen, the Haltech we mostly filled more data for the mapping sake rather than tune (but it did make me feel better having the detail).

 

I don't know, I may end up doing a 180 and going back to Haltech. This time around whichever I choose, I want to use the EMS to control a boost solenoid rather than a separate EBC.

 

Here's a fresh set of pics with the flares on the car:

Just a few more pics of the car after it was primed and the engine bay was receiving paint. Hopefully I'll post a few pics soon with the engine in place (then we will finish paint... we voted to not move the engine/transmission across fresh paint).

Very cool build. How does the circuit sport oil pan fit? Does it sit a lot lower than the sr OEM oil pan and is there plenty of room between pan and the crossmember? Thinking about running the same oil pan here

 

It actually fits really well. I will post some pictures once we have everything back together. Paint was delayed due to work/other projects, but I have a bunch of pics to post today. The quality is excellent on the pan.

 

build looks great!, love the zero rust motivation!

 

and does the sr use the original tranny mount and doe it sit behind the subframe?

 

I used new mounts, but the original mount holes. The new mount is just a simple bar that has a bushing block on top for the end of the transmission to rest on, then bolts up into the original mount holes in the body. There are two mount styles depending on the years. Some cars had mounting bolts running veritcally, some had bolts running horizontally. Here are pics of each (I have a 73 so there is overlap and I got the wrong one the first time):

Sorry for the long delay. My virus scanner kept blocking me from coming to Hybrid Z and I was so busy with work I took it as a sign that I should be doing something else. Here are some more update pics of the build. I decided to paint it white again, but we will be doing a large center stripe with two narrow stripes to each side. Ed Hubbs will be airbrushing some subtle Asian themed scene down the stripe using the similar methods that you would for ghost flames, then the whole car will get hit with another House of Kolor Crystal coat to make it all pop.

 

The engine valve cover will be getting painted after we set the engine. We don't want to worry about scratching it with the chains while we are dropping it in.

What are you doing for fuel delievery? This question is plaguing me currently and haven't really found a set in stone response.

 

What part of fuel delivery? Are you talking about tank and pump, lines, or under the hood? We decided to fabricate in a Z32 300ZX fuel tank, and use the OEM Z32 TT fuel pump. We are trying, not sure if it will work yet or not, to use the stock hard fuel line to the engine bay, another feed line as the return line (so they are equal sizes), and just a decent FPR at the front. If it doesn't work out, we will start tweaking things. My biggest concern was getting enough fuel forward, at a good pressure, and getting it back out since the old line sizes were for carbs not FI.

 

The car got hung up in paint. The guy doing the work had some personal problems that set him back on his schedule, but hopefully I will be getting more updates posted soon. We ended up having to respray the undercoating to fix some overspray and other issues from body work, so we did that right before we set the engine and transmission, bagged it, and sent it off for final paint.

We actually just decided after looking at the changes to get the Z32 tank to fit it would be much easier to use a 240SX tank. It actually ends up sitting nearly in the perfect position and seems to line up with the factory strap positions. The car should be coming back from the other shop next week so we can get back to fitting things. If all goes well, the 240SX tank would let us convert the spare tire well into a small tool box area, gain a few gallons of tank volume, and use the stock 240SX fuel pump assembly (or upgrade to whatever solution we want).

If your stock tank is good, it's not that difficult to put the stock sx sump, pump and mounting ring in it. You would need to shorten the pump mount a bit but it worked out fine on mine. I left the stock gauge in too. Just a thought.

There are a lot of little benefits to a more modern tank, and I'm hoping to be able to avoid needing a surge tank (although the new box area replacing the tire well would work quite well). I am also going to gain a fair amount of room to access the diff with the tank in place. I'll post some pics when we get back to working on it.

 

The plans are always in flux as we just pick through the parts around the shop and see what fits where the best and what makes the most sense for the rest of the designs.

Mini-update: Just a few pics when the car came back from paint. Unfortunately you can't see all the sparkle in the paint in these pictures, but it's amazing. Later I will get some video and high quality pics.

Nice build man. Great work ,any updates?

 

Also, you mentioned the tranny mount is a bolt in into the stock location, but what about the engine mounts?

Do those bolt to the stock holes too or are they weld in? Any pics of those mounts?

Thanks!

I had the same question, my mounts are custom and I was told to mount the mount to the engine then drop in the engine and where it sits nice you drill in holes for bolts. I don't know how the mckinny or vildini ones go though

Sorry for being away, I have been extremely busy. The engine mounts are the McKinney mounts on my car (there are a lot of similar mounts). They are a basic cradle design that just rest on the frame rails. In my case we installed them both with welding and hardened bolts. Basically we wanted a fail safe in case it came a part under hard driving at the track or on a long road trip. Here are some pics I have of the mounts. There are actually some lighter versions that I would have liked to use from JWSportCars.com but they didn't have any available when I started my project.

Now that I read over your thread and are spending some $$.  If you end up going with EFR and full race you might as well get their twin scroll manifold T4 style and get the newer/bigger mixed flow EFR turbo in the same twin scroll setup.  They've got dynos showing it still does better in response than a 2871r yet makes so much more overall.  You may find yourself with some clutch slipping and transmission issues depending on driving style and actual results with power.  Personally, I think I got just as much fun factor of a turbo upgrade by moving to the 350z 6 speed instead of the stock 5 speed SR transmission.  It was a bit of a pain though I admit doing the swap.

As for the 6 speed conversion, I actually have that on the list of potential upgrades. Initially I just want to get everything tested and bullet proof, then I'm going to pick an upgrade to do, test the heck out of that, then move on. I'm setting this car up to be as rugged as possible so that I can jump in and beat on it without worrying about having to fix it along side the road.

 

It's been a long time since I posted my initial build plans. Having spent some time talking to the guys at Full Race through email, I think I may very well do a twin scroll setup. I think the first phase will be to move to do ECU replacement so that I can get some time playing with it and tuning before I make big changes to the boost or fuel systems. The new Haltech Elite has me drooling a bit, and I maybe willing to delay buying other parts just to get that ECU and do some playing with it on the bits that came with this engine before I upgrade. It will just depend on the wife and how much money I can spend and how quickly before it becomes a "conversation"  ;)

 

Unfortunately my car was back burnered until this winter while we wrap up my Dad's 55 Buick, but it's almost done and then mine should wrap up fairly quick. The same guy doing work on his car is who was going to do my fab work to convert my spare tire well into a tool box and the wiring harness, but I gave up my spot in line for the Buick. His car just got a full undercoating, powder coated frame and suspension bits, fully rebuilt suspension, brakes, and engine. Right now the engine is going back together and some little touches are being done to give it a little something special before it is out the door.

Just an update for everyone asking what was happening with the project. I put the project on hold this winter while we moved it to another shop and the wiring harness is sorted. Unfortunately I hired a shop to do the work on the harness and it never happened, so I had to order another one through McKinney Motorsports... but now it's been a couple months and I can't get a hold of them either. Hopefully McKinney will get back in touch with me at some point or I'll find out what happened to them so that I can get back to making progress.

Casper - I had a very good experience with Wiring Specialties.  They completely took my Haltech Sport 2000 Harness and made everything to length, terminated the connectors (to include repairing the 83 Turbo CAS ends).  Wiring Specialties had it for 9 weeks, they had projects in front of mine and communicated that to me beforehand.  When I opened the box and looked at the completed harness, I was impressed.  Talk to Yury about a harness before buying anything.  He could have made me one cheaper than the one I bought from Haltech and then had him "cut it to fit". He was responsive to emails and answered the phone or called me back if need be.    

 

I took some pictures and did a write up on their work.

I decided to try McKinney Motorsports new offering of a customized harness as it is virtually to OEM spec for weight, wrap, etc. I hate a lot of custom harness work because they rarely use high quality and "excessive" durability wire. If I hadn't already ordered the wiring harness back January I would have been interested to get in touch with them. Hopefully this harness is as good as promised, otherwise I will be extremely pissed off waiting this long and double pissed if I have to go with another vendor in the end. This is already a compromise as I would have liked the first job had worked out because it would have been a nicely tucked and would have seemed almost as if it were OEM.

That looks like quality work. If this falls through I'll give him a call. The SR harness is an ugly blob.
