Ive pretty much decided I want to build a ka-t. I have pretty high goals for my project and want 400~450 whp on pump gas with torque to match or at least close to it, and all on a SAFE RELIABLE boost setting.
Im aware that the z32 swap is the way to go for oem transmission swaps for an sr(at least if you do not want to get flamed for bringing up an s15 6 speed ). Well I have a few questions if you all would not mind helping. Does mazworks make a z32 kit for the ka(or anyone else) ? Are there any OEM 6 SPEED transmissions that can be bolted up to a ka ? Like a t56 or z33 ? Something that is easy to come by or cheap if you had to replace it or parts on it. The reason I ask is because im a tight ass on spending my money. I have another deployment(iraq here I come) comming up in 6 months and will have about 7~10 to spend on my motor. Well I want to get my motor and drivetrain finished with that budget. I would love to buy a nismo/hks/os/whatever 6 speed, but im not "special olympic" enough to drop 12~20k on a transmission for a street car. I also prefere a 6 speed to a 5 speed. So any input is wecome. I read on another post that Xcessive made a z33 6 speed swap for the ka but I could not find it.

this sounds like a very intersting project.
i too want to go Ka-T, but idk about the 6 speed part. sounds pricey. And for the Xessive z33 swap, i bet there was alot of modification to make that work. -makua[ace]

I'm working on the KA 6 speed tranny project after I get my car back from getting it's cage...
Using a Z33 350Z six speed tranny that I got from someone who worked at a Nissan dealership... I spoke to Mazworz and they can cut you the adapter for and machine the bell housing so it can fit... Together I'm guessing he would charge about $650 for that... The shifter would sit about 4" too far back so you would have to make a custom bracket for the shifter as well as a custom rear tranny bracket... A custom driveshaft ofcourse... There is no speed sensor on the transmission... But I think I can make it work... It's far from bolt on so I'm guessing that's why they never made it as a kit... They would have to sell it for like $1500 or more...

How close are you to making it run ? Also when I called them about the same kit for an sr they said two things.
1. the z33 bellhousing was too wide for the s13 transmission tunnel(I have an s14 now so im not sure if the tunnel is bigger or not). 2. the splines for the transmission were a little off centered when mated to the sr. Thats why I never bought the sr kit they make.

FYI
T-56 (From A Viper Or A Vette Or A Camaro) Is 2600$ Brand New.....Used They Are 1200-2000$ Z33 Trany Don't worth it....you will shift way toooo often and with your 4.08 rear end...boy oh boy you will hate the car.... Supra Gatreg V160-V161 Is The Real Deal...That Thing Handel 1400whp 8.49s 1/4 mile run's easy.....Granted it's 5255$ for a brand new new trany and 3000-3500$ for a used one... If i were you i'd invest in q45 3.55 (90-96) or 3.69(97-01) rear end and you will get the kick out of your KA-T... Oh and cory's 563whp S13 hase a STOCK Ka Tran's.... $$$/benift KA trans > ALL (b/c it's cheap) Ali

and NO you wouldn't be constantly shifting the 350z guys switch the rear end for a 4.08 out of the Q45 and they say that first gear is almost usless for anything but burning rubber.

I would say stick with the stock tranny any just lower the rear end gears. Ali is correct, for cheapness stock tranny is fine. And if your goal is 400-450 then there are plenty of ppl making that without massive projects to have a different trans.

The Z33 six speed is just as strong or stronger than the Z32 5 speed... Others have taken them apart to take a good look at them...
The input shaft on the Z33 six speed is identical to the KA and SR.... The truck VQ tranny rear shifter bracket fits on the Z33 tranny to make up for the 4" longer situation or you might be able to just buy the VQSwap.com shifter bracket which already includes a short shifter... No idea on pricing but it can't be that much... The stock Z33 rear end has a 3.53 final drive whereas the S13/4 have a 4.08 (in most cases)... With the Z33 transmission and a stock S13/4 final drive it will make an effective final drive of a 4.6... A higher final drive means faster acceleration through the gears (and remember there is one more gear now) but a lower top speed... For a roadcourse racer like me it's perfect... We aren't running much top speed anyways... The S13/4 tranny tunnels are big enough for the Z33 housing... Don't forget that people are running full VQ swaps already without touching the tunnel... The bellhousing is bigger though and even Mazworx said it wouldn't fit in their machine so they would have to machine it by hand... And the Z33 is strong!... Bulletproof for my NA KA project... I'll never have to replace my transmission again... And since my Z33 trans only has 8K on it, It will feel like driving a new car... S13/4 transmissions are getting old now and rebuilding one costs about $800... I'd rather adapt this... Right now I am rebuilding the motor as my cage is getting finished... I have a super clean tranny already... It won't be another month until I start looking at getting this done... I'll keep everyone updated ofcourse...

So with the z33 trans on a ka24de would it be possible to have a tach, speedo, and reverse lights ?

Dunno,
All I Know That The Real trany to hold big Hp Is either a rebuilt T-56 Or A V160 Trany From A 6-spd Supra.... Example : YouTube - WOTM Supra in car video - [email protected] YouTube - Darin's Supra [email protected] And YouTube - Darin's Supra 6 speed record YouTube - Street Dodge Viper twin turbo 1700hp drag race. Can You Hear The "BOOM" At 00:50 That What 1700HP Sound Like Son... ![]() Oh And What Is The Fastest 6spd 350Z Record In The 1/4 Mile.....? Ali

I own an 01 z28 camero with a t56 in it. It has a really close ratio gear set but im ok with it. I also owned an sti which has a 4.11(or around there) ratio. I just prefere a 6 speed over a 5 speed. I like to auto cross and drift so I always want to have my max power band. Shifting is fun, plus a 6 speed ka24det would be a fun setup, and orig.

We test fitted the Z32 tranny onto the ka-t of the Federal S13 car. We used the mazzworks kit i believe.

IIRC From Ka-t.org alot of guys say the trany handel drifting-auto croos easy.....what kill the trany is lunching (Drag lunching) from a Dig..... Also In Drifting And Auto Cross you don't to shift too often...alot of LSx Swaped S13/S14 Invest in Q45 Diff....B/c Drifting In 4th Gear Is Crazy( LS1 S14 Drift car).... So Go With A Stock Trany And See What Happen, Regards, Ali

can you get a s15 tranny and swap the s13 bellhousing and still use your s13 clutch?

i have a z32 5 speed on my ka-t datsun 510. our fabricator could take the 2 bellhousings and mate them so it'll bolt right up on any of the transmissions you've mentioned, and as far as the splines on the input shaft , our clutch guy could build a custom clutch for it as well. it's all possible, it just depends on how much you have to work with on this project. i chose the 5 speed z32 instead of the 6 spd z33 because the 510'll be a daily/drag car and i didn't want the extra gears. we also have an s13 rear subframe /w z32 diff in the 510 as well. befriend a good fabricator and your options increase =]

Is there any chance you could get a quote on how much it would cost to mate a z33 to a ka24de and get it to shift right.
Would it be possible to have a working tach ?

the tranny for these applictions won't affect the tach working but if what you meant is working speedo then that too is not a huge hurdle that can't be tackled.
no sweat, pm sent Dave |

there is a speed sensor in the tranny.. at the end of the sensor is a gear that sticks in the tranny..that is what sends the signal to the speedo..any aftermarket speedo would work, and i dont see why the stock one wouldnt either

i was told that the s15 has a deeper well bellhousing and youd have to get a different (s15)flywheel to make it work(sorry to thread jack).
