Better off getting 1 piece driveshaft and TT diff and axles. I do not know about the driveshaft part, but the diff on na is R200 and TT is R230. The axles are also bigger like the diff. If you did not get the driveshaft from the swap, you would want a 1 piece as a upgrade.Originally Posted by 300z32x
Keep us update!!!
P.S. Do not forget about suspension upgrades!!!
i am keeping the R200 rear diff, so a Z1 custom 1-piece drive shaft was budgeted with a TT front flange (trans) and NA R200 rear flange (rear diff). the bolts dont line up on the NA and TT trans or R200 R230 rear diff on the driveshaft. It will work out better this way. axles and the R200 are more than capable of the power outputs.. the R230 would be pointless with a 3.89(?) ratio, hence why a lot of people switch to the R200 rear diff...
One step ahead the suspension has been tuned via Energy poly bushings, SPL aluminum subframe bushings, Stillen sway bars, Carbing Struts, Tein H-Tech springs, and KYB AGX shocks... no recent pics though...
Once engine is swapped if i can have the bottom end spec'd out as plan before the drop i will be able to squeeze out some pretty impressive number on stock heads and stock fuel system on race fuel... i am going to aim for about 18-20psi on race fuel, and 15psi on pump until the fuel and turbos are upgraded... then head work comes next! im looking for a total power output of around 660+whp on race fuel at 23-24psi, and 535ish whp on pump at 23-24psi.
*edit*
Next Update will be when i order my engine, trans, etc. Then i will do a super detailed write-up with pics off my work, parts, trouble spots and maybe the entire swap.. to be used as a future reference (future sticky?) for anyone else who wants to do this swap...
Wish i did this when i helped my buddy with his swap!

What are you doin with the na engine and tranny?
more than likely rebuild then sell, the tranny is an auto, i will have it clean inside and out, freshen up the torque converter, and seals.
the engine will recieve a new gasket set, and maybe 120K kit
why are you intrested in purchasing them? you can rebuild em

Naw man after thinking about it Im gonna keep saving for my tt swap.more than likely rebuild then sell, the tranny is an auto, i will have it clean inside and out, freshen up the torque converter, and seals.

why are you intrested in purchasing them? you can rebuild em
i highly recommend the TT swap, its soooo worth it... plus in a vert would be amazing! this would be my second TT swap, one on a buddy of mines and now mine... you get wicked fast acceleration from the NA rear diff. once the swap is done the start is a very proud moment, and the first time you make boost will feel like you lost your virginity all over again. even if you keep an auto tranny, with great traction, it still makes for a fun car. you could punch it and still spin tires, it will be a completely different car.

About how much did it cost all together?
My swap is a pricey swap due to assloads of aftermarket products used, plus new OEM products aswell, but a ball park figure for my swap is in the around $7000 (without bottom end build up), but that is with a very reliable build, 460-ish whp @ 15psi once swapped. subtract the cost of used JDM OEM stock products not going to be used that i will sell (which includes clutch, resurfaced flywheel, harness, ECU, and an extre 60k kit)... once all is sold it will be around $6000-$6500.
A simple RELIABLE stock swap would cost around $3500-$4000 depending on what you want new (i recommend mounts, harness, radiator, all hoses and 60k kit)...
A JDM front clip would be they cheapest way for a decent swap. $2750+ but that is using stock used JDM parts, and i dont really recommend but some peoples budgets are smaller. I've been planning my swap for a loooong time and saving for a while also... lol i still need a bit more money to complete the swap.
Read into the swap, find out as much information as you can, ask people that have done this swap (feel free to ask other question; i might not have the answers to some questions... so give Z1 or Z Car Atlanta a call, if other people can't help), the swap is kind of tricky and that was with a friend on his Z... im doing this one solo on my own Z. money will disappear but once the swap is done you will be super happy with the results!
Good Luck!
"Your Z sideways is a N"
dont know if your still looking for the stuff but you can everything you need to swap over right here http://cgi.ebay.com/ebaymotors/1991-...QQcmdZViewItem
ouch! why would you show me that? that hurts the heart!
thanks for the link but i should be set... i would hate to buy another Z just for the engine. plus i have ordered most of the parts i need all i need is the engine, trans, and components plus a few other misc. item, that i found a great deal on already! and budget isn't right yet to pick up that, just yet... i wasn't going to do the swap until april or may-ish. plan to have all the parts and everything installed by mid-late march. if budget is right might go with bigger injectors and turbos plus sending my ECU out to get re-tuned to compensate for the injectors; or Z1 Ultimate rebuild kit before dropping in the engine. that means i will have an extra 60K kit if anybody is intrested in pruchasing one.
"Your Z sideways is a N"
Thats not a twin turbo...
Oh yeah I have had my Z for almost 2 years and have been doing research on the swap since then. I was just asking because there is no better way to get an answer to something then to ask someone who has already done it once.
And the first turbo car I have ever driven was in fact a twin turbo 300zx...and yes...I lost my virginity all over again lol
Well then you should be in good shape to do a this, its really not all that bad its just easy to get frustrated IMO (short temper). By the time im done with swap i will be a NA->TT swap master!.... when your swap comes around let me know if you need a hand!
lol a twin turbo 300zx is not the same car as a NA-TT 300zx... acceleration is the main difference! my buddy raced his stock swap'd Z against a stock TT, and absolutly waxed him!
The NA R200 rear diff (4.08) will be fine, the axles will hold up just fine aswell... I've heard some high hp (450+) 240sx's also using NA 300zx axles. I will be doing this swap very right, very organized (baggies and labels), and very detailed for all others
*edit*
as of now while its still NA my Z is my DD, but i am also doing a QR25DE swap into a 89 nissan pulsar (uber light, and old DD), lol that car is going to zip, and be my DD!

Oh I know that. The rear diff makes it accelerate much faster. Im just glad it was a Z I lost it too. Once I felt those twins spool up and my body start going deeper into the drivers seat...I knew I would have a twin turbo Z one day lol.Well then you should be in good shape to do a this, its really not all that bad its just easy to get frustrated IMO (short temper).

IMO, I would take the smaller number final gear for gas mileage. But I do my project around my DD, so mpg is a huge factor for me. But if this is a racing project for you, then I would go for the 4.0 something diff. What are you going to do with the output shafts and axles? People with high power 240sx breaks their axles and do the q45 conversion...
Keep us the update cause my friend would do the same if he can find a good, cheap z32. I believe you are doing everything right and it will have a great outcome.
based of looks interior and extrior, performance both handles and power make the Z the holy grail of the automotive industry, with a great sticker price, even when it was new!
"Your Z sideways is a N"
for anybody else intrested in this swap i found a GREAT deal on a VG30DETT engine set, WITH FREE SHIPPING all for $2195!!! this is were i am sourcing out my set... it include complete motor, throttle bodies, 5spd transmission, clutch, flywheel, harness, all required cables, ECU, alternator, starter, PS pump, PS high pressure lines, A/C, fuel rail, injectors, manifolds, and turbos. a buddy of mine has bought an S15 SR20DET from them and stands behind them. so i will try ordering from them and maybe second that.
http://www.jazzproparts.com/VG30DE_TT_p/vg30de%20tt.htm
I will be purchasing from them hopefully by early-mid march and will begin the swap as soon as it arrives.
"Your Z sideways is a N"
I am almost ready to purchase my engine set to finish things up on my swap.. I found a lot of Z owners helpful over at www.fairladyzx.com
"Your Z sideways is a N"
Okay swap is getting ready to begin with the final purchase today!
Todays Purchase: VG30DETT engine set and 5spd trans with Z1 clutch, flywheel and driveshaft, SSQV's, AND Z1 Ultimate rebuild kit (now looking to boost around 20-23psi, since heads will be stock)!!!! This also means I am officially broke!
Also I sourced out a used OEM TT AC kit out of a totaled 96 300zx.
Once the engine arrives I will break it down and take it apart, and prep it for cleaning... I will throw the bare block and the bare head in a Steamer for about 20-30 minutes... I will then Cyro treat them along with the Tranny for extra strength. All while cleaning the guts of the head, valve covers (then powder coat), and other misc items... Once all is done start piecing the motor back together with the cleaned OEM and new aftermarket goodies so I can just drop the motor in add fluids and crank it up!
All while ^this^ is going on I will also be removing the VG30DE components, and prepping the engine bay. Than apply the same cleaning methods on the DETT for the DE, then put on the new gaskets and the 120K kit and put all left over parts up for sale...
"Your Z sideways is a N"
hah, that's usually how it goes. i'm in the same spot.
good luck on the build though!
have you tried twinturbo.net?
i've tried a bunch of sites, used info from TT.net... but got questions answered from other people that have done this swap aswell over at www.fairladyzx.com
"Your Z sideways is a N"
Even though we are broke know soon we will be content with it... As the 300zx will be a completely different car, MUCH-O EL FAST-O!
"Your Z sideways is a N"
^^ yup, same here!
hey jsut to let u know i found a 300zx twin turbo mint condition 86000 miles for 5000 grand on craigslis,org.
I am plenty good on another TT-Z. The Z still has yet to be completed due to an amazing deal on a 92 Acura NSX. The NSX wasn't running right and so I have been investing a lot of time trying to fix the seized motor, and bent valves!
The Z will be running before the end of this month!
**edit**
I might try to make time to wrap it up this weekend! Its near complete just need to drop in the motor and trans and wire it all back up!
"Your Z sideways is a N"
Actually I have seen a VG30DETT powered Z race a LS-powered Z and the VG owned him on Dual Intake, cat-back exhaust, injectors, and ECU, with boost right at 14psi.
I am not saying the LS is a crappy motor, but just because you have the LS doesn't mean you going to be a beast, its hard to fab aftermarket support on the LS inside the Z!
"Your Z sideways is a N"
if you need a front clip, i got a buddy who wrecked his Z... its a 1995 with 67k miles. He just spent liek 2 grand on installing new 740cc nismo injectors and not even 150 miles later a lady totalled his ****. I think he wants around $4000 for the clip. That includes almost everything from the shifter forward.
