240SX VQ Swap - Project S13 V-Spec with VQ30DE from Maxima.

What is this 3rd throttle control for? I can see the main throttle control and the cruise throttle control, but not really sure about the 3rd. Looks like it's vaccume activated or something.

[Soravia]

I'm thinking about making a drive shaft fab out of the stock OEM auto drive shaft before I go on to getting an all aluminum shaft. What is the difference between 350Z/G35 6MT output shaft pattern and the KA24DE 5MT output shaft pattern on their transmissions?

Are the shaft patterns on the G35 MT and AT different? Or is it just the overall length?

144.5 lbs

That's the weight of a 350Z 6-speed transmission with full fluid. It'll get here on Thursday. I'll be buying the oil pan for it as soon as I'm done tearing it down for inspection. Hopefully the thing will be faultless. Most Z owners are pretty abusive.

I got a chance for about 3 hours to work on my S13 today. I just need to unbolt the drive-shaft and pull out the engine and transmission now.

I'm looking to buy a G35 drive shaft end on the transmission side. Anyone have one for sale?

[Soravia]

I just worked on it a bit today.

The 6 Speed came in.

The car on jacks and engine hoist.

I tried to take the transmission out. Got the mounts and drive shaft out. But the thing won't come off the engine after taking out 10 bolts from the bell housing. WTF??

just looking at your project thought i would tell you about what you where askinging about on this pic. this is a coolant thermater coolant passes through behind where the blue corated area and as get gets hotter it moves outward and what this does in sense controls your high idle and when, i would like to say if you take it apart plan on buying a new one it is like wax inside of it that expands when hot pushing the plunger outward curving the high idle but i thought i would help you

[Soravia]

I don't like coolant getting anywhere near my throttle so I'll remove it. RX-8 owners found out that not running coolant makes the throttle a whole lot cooler.

I've decided to buy a Maxima flywheel and bolt the CPS ring to the 350Z flywheel.

Quote »On Mixing and Matching: Basically, the flywheels have a timing ring on it that is read by the Crankshaft Position Sensor, and if you use a 6-speed flywheel (which has a timing ring meant for the VQ35DE ECU) on a VQ30DE engine, it's not going to read right.

But, if you plan to use a 6-speed transmission, the 6-speed flywheel sticks out further towards the transmission than the 5-speed flywheel does. In other words, the 6-speed transmission will never engage the 5-speed flywheel because the throw-out-bearing can't reach that far.

So, you can't use a 6-speed flywheel because the CPS won't read it properly and much up timing and stuff, and you can't use a 5-speed because it can't reach the TOB. What do you do? You have two options: either weld the 5-speed timing ring to the 6-speed flywheel, or talk to Travis aka TurboS13Hatch of Maxima Forums about buying a bolt-on timing ring that has the proper timing teeth as the 5-speed flywheel, but bolts on to the 6-speed flywheel. Now, you can use the 6-speed transmission with 6-speed flywheel and still use the VQ30DE and/or it's ECU with no worries.[/quote]

damn i cant to see this when its finish

[Soravia]

I figured out why I can't pull the transmission. The auto trans (which I haven't owned in 4 years) is bolted to the flex plate and needs some PITA work to come off.

I'll just lower the front of the car and raise the rear to pull out both engine and trans together.

BTW. I'm looking to buy a 350Z flywheel & Clutch kit. cheap

[Soravia]

I ordered a set of poly mounts from eBay. Includes transmount bushing as well. Same price as in fab market section, but with trans mount included. $122 shipped. Hopefully it fits perfect.

[Soravia]

$121 for upper oil pan from dealer! Should get it Tuesday.

[brandonDavid]

lotta hard work and diy going on in this build, i'm gonna stay posted. it looks awesome man.

[veebee]

quiksteel should sponsor your car with as much of their product you've used lol. this is super interesting, though, can't wait to see it when it's all done. i love diy/originality build ups like this

[Soravia]

Nice coupes you got there. Ever tried swapping the two front ends? LoL

I just got the engine and trans out of the car. The driver side motor mount was broken and on top of it, the nut got stripped. The thing is also very hard to grap because the steering rod connector is in the way. >.<

I'm going to cut the rubber with a saw and grind of the bolt from the mount. I need that engine bay cleaned of ASAP for some Semi-gloss black paint.

The trickest part about DIY is finding time and location. I'm just lucky to be able to work a couple of hours a day after work. Makes me want to call in sick and spend the whole day there. :P Can't really do that with the economy slow down though. If the boss figures out that he can get by w/o me I might end up going on a job hunting. LoL

[veebee]

haha yeah that's true. as far as front ends go, no i've never swapped the two lol. a buddy of mine has a coupe with an s14 conversion up front (s14 sr, kouki front end) and i'm truly not a fan. i'll stick to silvia fronts on coupes, and s15 fronts on hatches, lol.

[Soravia]

I'm looking at the F1 Racing flywheel from ebay. It seems to be steel that I can weld in the Maxima sensor ring. Except that I don't have a clue which goes where.http://cgi.ebay.com/ebaymotors...ZWDVW

Anyone have close up pics of both flywheels?

[Soravia]

Looks like the bottom of the Z transmission housing has bolt holes. I can use those in my plan to make under-body aero trays for the S13. I'm looking at aluminum sheets from Lowe's and Home Depot for that.

[Soravia]

Got some flywheel pics for stock and JWT. Nice close ups showing the sensor ring.

[Beancooker]

Awesome build you're doing man. I'm impressed. I'll be glad to see it when it's all said and done.

Aluminum and steel have different temps to melt at. That means aluminum would be evaporating at the temp steel melts.

I need a TIG welder to weld Aluminum to Aluminum. Those things are huge and expensive.

Get a spool of aluminum wire and a bottle of 100% Argon gas. It is possible to weld aluminum with a MIG. Run a higher pressure of argon to keep the area well shielded from oxygen. Keep the heat low, and wire speed high.

[Soravia]

I dream of Twin Turbo (about 600HP)

[Soravia]

Took me a lot of time looking for a sensor ring and I found one right here.

at the back of my engine. LoL

[Soravia]

I'm planning to use the front header from the Maxima to clear the steering shaft and be able to lower the engine more to clear the hood.



Let's hope the thing will clear the crossmember.

EDIT; It doesn't. The only way seems to be to mod the stock Z33 manifold.

[Soravia]

Bought a Maxima A32 flywheel and a Z33 flywheel. Let's see which makes the easiest mod.

[Sleeping240]

nice.. gotta keep an eye on this one

[RCA]

Awesome build! I have never seen a person do so much of his own work! Ussually you hear what intake mani will fit and where can I get it...

Naa you just build one lmao! AWESOME job!

I dream of Twin Turbo (about 600HP)

SO WORTH QUOTEING...That is the sickest 350z I have ever seen! Modified Mag did a great cover on it. The fabbers @ Jun are magicians! They sure as hell used alot of quiksteel

[Soravia]

Proof of JDM tyteness

LOL

PITA to unbolt. Wedging in a wrench helps.

The crank is held down like this to unbolt the torque converter from flex plate.

A32 Maxima flywheel just came in.It weights exactly 20LB with the sensor ring bolted in. Might shed half a quarter pound if it was welded instead of bolted.

The distance between the back of the flywheel and the teeth on the ring gear are about a quarter of an inch. The sensor ring teen are higher than the back of the flywheel. There is also a thin 1/8" aluminum spacer that goes between the flywheel and the crank.

If I use enough spacers between the crank and the Maxima flywheel, I might be able to resolve the issue of 350Z starters breaking when used with A32 Maxima flywheel. (Most likey because the A32 flywheel gear teeth sits closer to the starter)

Now I need some measurement from the Z33 350Z flywheel. The thing won't be in until next week. IF it gets shipped tomorrow.

[Soravia]

How can I test the solanoid on the starter without turning the flywheel? I'm trying think of ways to test the fitment between 350Z starter and Maxima A32 flywheel.

[RCA]

Go to a parts store and ask for a Z33 starter and a A32 flywheel.
