Rebuilding Dr30

[sr201600]

I am currently rebuilding my DR30 and need advice on a couple of things

*Does anyone in Aus have replacement driveshaft or someone that rebuilds or exchanges them

*Im looking for a turbo that will bolt to the standard manifold and by able to support 300 -350 atw hp

*Also what size injector would be required

*Does anyone make a patch loom for a aftermarket comp for the FJ

*Does the car sit very low when swapping to S13 coilovers in the rear

*Who is the best nissan dealer in qld to see about getting part nissan japan

any help would be great

are you referring to the gearbox to diff? or the diff to wheels?

if diff to wheels, the shafts from a Z31 300zxt are bulletproof (from import wrecker) also plenty of custom places can make them, also the subaru WRX gear is VERY similar and can be adapted with some research or experience

GCG make some of the best turbos available, and can pur something together to suit the stock manifold bolt pattern with your choice of front housing and turbo trim

somr GTR 440cc injectors should be alright, normally take the total HP aimed for and add 20% and it gives you the MINIMUM cc's... very basic guide

Adaptronic make an excellent ECU, is aussie made, and hass all the features of a $3000 motec or similar. but a shitload more affordable (like $1500 tuned and installed) I can point you in the right direction of someone who has one, they may be interested in getting the tune copied as a basepoint

S13 coilivers should get some that are height adjustable, problem solved

There arent any R30 parts specialists in australia, but importmonster have some good links to yahoo japan, you can get HEAPS of good stuff

SSS in Sydney accasionally bring in a frontcut or 2

Depending on what's wrong with your own half shafts, just about any CV repairer can do them. If it's just the boots gone, just replace them with a/mkt replacements.

As Mag's says, the Z31 Turbo or HR31 half shafts are the ants pants, but they are nearly as hard to find as rockin horse sh!t. I just purchased a set for 35000 yen for my track DR and with freight into Melbourne warehouse they will cost me a tad under $800.00. But, it's not just a simple swap, the inner flange needs to be changed as well, meaning an rebuild of the rear trailing arm, but once this is done, you will never break another half shaft.

Turbo's ........... well these are just about anything goes, but for 300+ rwhp you could get an VG30 hi flow, or an GT3082 or similar. The first thing you have to decide is what your going to do with the 300+ HP, are you going to drag it or track it, because turbos are different to what purpose you want it for. I just bought a custom Billet D-GT2 for my track DR from Mr Turbo in Queensland and it's relatively small due to response required. If your going to drag it, then lag isn't a problem, but on the track, you want as little as possible.

Injectors ........... to support 300/350 comfortably your going to need about 550cc & I have 4 that have been cleaned & flowed from an S4 RX7 low imp plus 3 not done. You can have the 7 for $250.00. 440cc as Mag suggests will do the job but the duty cycle will be getting up there.

I am running an Adaptronics on my DR30 and it appears to work really good so far. May I suggest you do a search on their web site for an installer/tuner in your local area if that's the way you choose to go, but get a new ECU, don't screw about with copgy back ideas.

As for DR/HR import parts ............ good luck, as they are getting very thin on the ground in Japan. SSS can't get enough of them and between Stewart Wilkins and myself, we buy everything they can get their hands on. We are both looking to the US but haven't had any success as yet.

Hey Dennis

interesting info!

for a road car whats a good (next one up) from the Vg30 that has the nissan flange? my Vg30 is leaking oil from the front cover, and id like to go a bit bigger giving me tuneability for future mods. i dont mind lag.. infact i kinda like it haha

was thinking about the factory turbos of things like the Gts25t or such??

Hey Dennis, a few mates have found the HR31 half shafts turn the glass after 450rwhp have you had this problem yet?

Marc, id be trying to hunt down a HKS T04E kit for your FJ, should be a bit of fun!

[Ghostrider]

No I haven't, but I don't have 450hp and really don't think I need it for my fun toy. I have changed the diff ratio to 4.11 and think I'll have more than enough punch on the tracks I have available. Eastern Creek I'll change to a 3.7, but for Wakefield & Winton I think I'll be fine.

If I send you over a rocker cover, can you get it done in the same magic red colour as the manifold?

Cheers, D

Yeh dude i smashed out an email this morning. I have a throttle here I can get painted up for you as well if needed.

Marc,

I have an R34 NEO turbo for my new L28et, but I'm not chasing masses of HP either. With 380cc injectors & relatively high compression, I'm trying to get torque as opposed to HP.

I do have an VG30 hi flow, but am reluctant to part with it for now, but I think they are the best of the factory options and they can be sourced for about $300.00. As it has been suggested the HKS T04E would be fun, but again, anything with the HKS logo is expensive. There are all sorts of combinations available with a T03 mount, just be careful not to buy a T70 Chinese model that does not spool up at all.

Cheers, D

whats a Vg30 turbo off? is it of a v6 nissan vg30 maxima turbo? or what ? is the turbo of the neo bigger than a vg30? to be honest id never heard of a vg30 turbo until i got to aussie so i dont no its trim, impeller or housing sizes??

[Ghostrider]

Z31 turbo is the VG30 to use as the Z32 has 2 smaller units and used individually aren't worth much at all.

Cheers, D

I havent seen a T04E kit for an FJ on Yahoo for a while
