They are much stronger than the universal joints for us stock s30 guys...But you have to have a 250 buck adapter to make them work.

On a 15in wheel, 4.5bs is as much as I can use with a slick with no spacers...maybe a 5-5.5in if stiffer sidewall...

Not unless you get into complicated custom strut angles and stuff.... Are you talking of a s30? You could with a spacer but I assume you are talking about stock locations..What diameter wheel?

I didn't hear anything.....So I always start laughing at the guys at the track that tune by ear, and claim the just change the tune when they hear it....yea right...

On the later models w electric pumps you can have a pressure regulator go out and cause the same problem.... Just figured I would put this in in case any one searches for this problem.

Yea, mine is going great at 14psi right now...need a good clutch and to install a lsd, but already hurting feelings at the drag strip. Is there no sound on your video?

You go with yo bad self...

Make sure you do what datman says or what Phil did and use a the stock z wastegate actuator or a low psi one....If not the holset one will most likley put you over 30psi, and we don't want that..lol

Loved it...Where can I find a few demo crews like that?

DDDDuuuuhhhh... You know I had looked over this already and missed it, Thanks and these are nice and a heck of a lot easier than trying to magnify the haynes manuals. One more quick thing, Why 2 fuel pump relays? I'm very weak on wiring issues.

I'm in the process of doing a little rewiring and would like to find out what the under hood relays are to... There a 4 of them under the relay cover and I think through wiring dia.... They are 2 fuel pump relays, 1 AC relay and I can't figure the other out... It has 5 blue wires and 1 green wire... Is it the ignition relay? Thanks

Several people make 350+hp with stock pistons and rods... read some of the turbo na post and post on how much boost pistons will take...detonation is usually the limiting factor.Also read up on differences in na and turbo motors...they both have the same compression if later models and the pistons are cast only with differences in where the ring lands are cut.

On the subject of the TKO...Don't overlook there are 5 types. 3550-TKO, TKO,TKO-2,TKO-500, TKO-600. Which is he using and what kind of cost is involved in getting it to bolt to the L6?

You must have used the datsun rod...there is a difference in approx 3in between shifter locations, the ford rod is too short to reach. The input bearing retainer is 4.9in o.d. datsun is a 4.8in o.d.....the hole in the datsun bellhousing is to small unless you pressed it on "which I don't think can be done" or removed some metal.... As far as handling power goes, Garrett76zt stated in older post "I feel like the tranny would have held up just fine at 18psi/pump gas (340hp)" after he did his in running 11.8ET runs...seems that the torque levels of the l28 are what kill the trans after doing some reading, which Zgad talks on. "I was making somewhere around 430hp/470tq to the wheels (per a recent set of dyno pulls) at the time" on N/A trans from your old post...so your probably right about that..I should probably invest on the next step higher being the z32 trans. I just wanted to document some of this info for members to think of all the work and options involved.

Yes, mine and big-phils were at 20psi before detonation took over...mine would have been fine I believe, but had problem with edis causing timing not to change....Which I had no clue of till afterwards.

I need a few sets of spacers for the z31 5lug hubs like Kyles drawing, for 240z and 280z...But could they be less complex? My 280z hub 4x4 brake spacers from jsk were simple flat circular design....

Thanks for the quick follow up Tim, but I did know yours was a g-force unit and do realize they are much stronger but, I could not afford to do this right now...plus don't have near the power you do yet...How much is a gear set from g-force, I'm thinking they are over 1000 bones...I know your trans is probably a great one, just not what I needed at this time. The t-5 might be a better option for some.... Tim when you say the center section will bolt right up, I know it will but also know a ford bearing retainer will not fit the housing without machine work to one of the parts plus the shift rod will be too short...right??? Not to try to make this sound like a hard job, but I would have to have a datsun t-5, buy a WC trans, rebuild kit, shifter, custom centered clutch, and have to pay for the machine work or other work I could not do...ending up with a T-5 that handles the same power as a KA trans, which are cheap as dirt, require machine work, that I can do at home, same clutch, same shifter... It just make sence to me to not to the T-5 unless I could go g-force.. How am I making it sound harder than it is? If I'm wrong about anything, let me correct it early on...Thanks and more power to you Tim, your car is tha shiznick.

These are notes that I was taking to plan a WC t-5 swap into my turbo L-28 280z, after seeing all the changes I would have to make to the trans, I have decided not to do the swap. I'm posting these notes to let members know what's involved...Feel free to add anything or comment on the process...In my opinion there are not a lot of detailed post on this process, which can be done in many different ways...I will discuss a few and talk about the cost involved...Like I said I have decided to do a different swap...which will be a KA for now seeing the cost and power it will take. From what i've read Timz and Speeder both have custom WC t-5 center sections w custom datsun tail housings, which is going to require a Datsun t-5 bell housing, shift fork rod, tail housing, and custom clutch to fit the 10 spline of the ford input shaft...Ford front bearing retainer will have to be machined on the o.d. to fit smaller hole in bellhousing or housing hole enlarged...It is also possible for the retainer to be shortened. I would think it would be cheaper and easier to machine the retainer. Tail housing will have to be modded for a larger seal being the output shaft is larger in dia.. Timz told me that the shifter hole in the z had to be modded some to make shifter work even though the datsun tail was used. I have read Speeders post that you would also have to build a custom mount too.... So if you plan this swap you will need one of each trans to start with. The inputs are different, both in spline numbers and the flange the blocker rides on...I think you could swap them if you wanted, as long as you used the correct retainer and the blocker from the orig shaft. The tappered bearing appears to be the same...The datsun shaft looks to be weaker due to it's smaller dia. The outputs are the same length and so is the overall lenght from tip of input to tail shaft, numbers of splines are different....Bell housings are different depths along with the retainer bore. To use datsun tail housing you will have to machine for larger ford seal and the bushing changed inside, being you will use a larger dia yoke for the ford output. I dont know what you would do about the speedo gear being it's in different locations on the output shaft. If ford tail housing is used it is going to put your shifter around 3in foward of the datsun location...you will probably be ramming it into the stereo when shifting if no custom shifter fabbed. Now about the cost.. I have a datsun t-5 ..Free...A possibly good ford wc t-5 is going to prob cost at least 200-600+.. WC t-5s were rated at different hp and tq levels....and most out of the stangs have been beat over time, so plan on buying some parts..The gear box on ebay offers a 2.95 gear set that brings the tq up to 335lbs and 350-400hp for 361.00. Billet syncro keys for 60.00..The deluxe rebuild kit is 265.00..yoke is 54.00...Plus what a good shifter cost and throw out bearing...So your talking about well over a grand for a rebuilt trans that will only take 350-400hp....I can pick up a KA trans used that has been in a low hp car for less than 100.00 ....the shifters are ok stock, you can use your same clutch, a housing off a old datsun trans modded youself...So the KA will handle from what i read the same power, and I can build it for near nothing...If I end up w more power I will go to the z32 trans which will take 600hp, and you can do that for around 650 total..if you do it yourself...Why go T-5? .................................................................Ford WC T-5 ................................................................................Datsun T-5 Input bearing race o.d. ................................-.668 .............................................................................................-.621 Bearing appears the same Input Splines .................................................-10...................................................................................................- 24 Input Shank ...................................................-1.005..............................................................................................- .906 Input rear seat for blocker 2.4 Larger on datsun Pilot bearing shank ........................................-1.0 ................................................................................................-1.100 Splines start back .........................................-1.150 ..............................................................................................-1.730 Front bearing retainer Datsun is too small for ford input shaft so you would have to use ford part OD of part .......................................................-4.911 ............................................................................................-4.855 Taller by ...........................................................-.850 Through out bearing bore or area where through out rides ............................................................................-1.431 ...........................................................................................-1.296 Output shaft Over all length is the same on both shafts splines................................................................- 28 ...............................................................................................-26 Spline length .......................................................-4.2...............................................................................................- 3.1 spline dia...........................................................- 1.18-1.2......................................................................................- 1.085 Speedo center from end of shaft ........................-9.3...........................................................................................- 5.7 Shifter location measured from frt of tail housing to far side of shifter mount surface ..............................................................................-12-3/8 .......................................................................................-15-5/16 Shift fork rod.......................................................- 17..............................................................................................- 22 Tail seal o.d. ......................................................-2.368 ...........................................................................................-1.982 Tail bushing ...........................................................-1.5 ...........................................................................................-1.3 Trans mount to center bolt hole.......................- 5.5.................................................................................................- 6.5 Warning these measurements are as close as I was able to measure with the tools I have compairing the two trans....It may not be exact, so use caution if using the for a build.

My bad, his name is cold fusion...ask him if he is interested an making some.

I have a old ESAB plasma....I love it.

He's right 5-600... But if you have time to watch z31.com classifieds, have them some times and don't know what they have and sell cheap... I saw one sell on there for 200 a while back. Good luck

He does sell the spacer alone...I too would be interested if someone would make a run of the spacers... Ask coldfusion.
