Hey my gotchilla mateys

I'm looking to buy a gtst r34 and planning to convert the engine to a RB26DETT from a 33.

since the gtst are only rwd. what would i need to make it 4wd?

would i require a whole front cut suspension or just the gtr diffs, if so would i need a 34 front or a 33 is fine?

also. what other bits and pieces would i need that differenciate the gtst from the gtr, i know there is the brembo brakes and capliers. are the injectors and fuel pump the same?

regards

rb25 aka (rice boy age 25)!!

It's GT-T R34, i'm not sure about R34s, but the R32s and R33s came out in a GTS-4 (AWD GTST) version. Main difference is ofcourse, the RB26 engine, AWD system, Body shape and materials.....

CLARIFICATION: In my previous post i meant SOME of the major differences between a GTR and GT-T that is, difference between a GTS-4 and a GTST is the engine (has a front diff, i.e different sump although this is interchangeable with a regular RB20) and the AWD.

uh.. would u know if there is a gts-4 for a 34? would save alot of hassle.

so the entire floor pan to awd. if i was able to get a whole r33 front cut. would everything there be sufficent enough as i heard the 34 might be a little different from the 33 settings

Yes there is a NA version of the R34 available with ATTESSA. I don't believe it qualifies under SEVS, however.

It does qualify, just very limited plates available for it in Aus...www.imports101.com.au would be able to find one for you...indicated price was round $19-22K

[the amount of $$$$ it'll cost ya, just buy a GTR......easier, and its designed properly]

lol. who can afford a 34 GTR?. i've been asking around and i might just know someone that can offer a good price for the swap. but would it take a whole r33 front cut to do it?

Best thing is not to bother with the 4WD unless you do actually buy the R34 25GT-Four otherwise there is a lot of fabrication around the front driveshafts and chassis to be done on the regular GT-T...ideally to cut cost you should start with a 25GT instead of the GT-T only major difference being smaller brakes (you should upgrade to the GTR calipers and discs anyway) no HICAS (no big loss)

hey dan. thanks for getting back to me so quickly, i'm posting here as well

ok so if i aquire a 25gt or 25gt-x r34 with the attessa. pretty much if i do an engine swap. then it can almost be branded as a gtr aside for the brakes and all and would i need a 34 gtr ecu? or any aftermarket will do

in other circumstance

incase i can't get my self the 4 version. and had to go with a gtst, and want 4wd. all the goods from a front cut will do the trick. money aside.

You have got to understand that between the three models of GT-Four, GT-R and GT-T they are very different cars. The front rails are different and need to be altered in the RWD, same with the floorpan (especially under the driver for the transfer case). The wiring is completely different, which then impacts other devices like ABS.

Then to top it all off you want to use an R33 front cut. If you want to do the conversion properly (aka everything working 100% and looking like a factory job) you really need to start with an R34 front cut. For the price of an BNR34 front cut + the initial cost of a registered R34, then other bits like interior, rear end, brakes etc you're easily looking at the same price as a GT-R outright. Add on labor and workshop charges and it's just not worth it.

If money isn't a problem as you suggest then why don't you buy a GT-R from the beginning?

I'm just a layman, but i would presume you do not need to change your drivetrain to put an rb26dett motor. Just try and get a hold of one without the gearbox, as you wont need it. Just the same as putting one in any gtst.

but yeah, you'd be seriously biting off a big chunk to convert from 2wd to AWD. What a nightmare!!! and what are you getting - a gtr that looks like a gtst... Why bother, other than for people to laugh at you when you tell them how much it cost to do. Get an r33 GTR if you want 4wd, you can pick em up for under 40's now

    • Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?
    • This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?
    • So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!
    • OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.
    • OK, so regardless of whether you did Step 1 - Spill Step 2 - Trans pan removal Step 3 - TCM removal we are on to the clean and refill. First, have a good look at the oil pan. While you might see dirty oil and some carbony build up (I did), what you don't want to see is any metal particles on the magnets, or sparkles in the oil (thankfully not). Give it all a good clean, particularly the magnets, and put the new gasket on if you have one (or, just cross your fingers) Replacement of the Valve body (if you removed it) is the "reverse of assembly". Thread the electrical socket back up through the trans case, hold the valve body up and put in the bolts you removed, with the correct lengths in the correct locations Torque for the bolts in 8Nm only so I hope you have that torque wrench handy (it feels really loose). Plug the output speed sensor back in and clip the wiring into the 2 clips, replace the spring clip on the TCM socket and plug it back into the car loom. For the pan, the workshop manual states the following order: Again, the torque is 8Nm only.
