I can understand having issues with the plenum,however i'm using a greedy inlet manifold with a sub zero 80mm billet throttle body.I'm more concerned with cam cover issues,pretty much everything else should take care of it's self????

Has anybody given there respective rego depts a change of engine no. and not been asked for a look at the change over?Thats to say notified a change of engine no from an rb25 eng no to an rb30 eng no and not been asked or quried?

Regards,

SKYLINE (Kym)...... :innocent:

This is a really long thread now.

I remember near the start someone was collecting the info to be put in a word document and posted up. Did this ever happen?

Further searching has come up with this:

http://www.skylinesaustralia.com/forums/sh...ead.php?t=35556

So Joel, did this ever get posted?

Thanks.

Oh wow son of rajab help me son of rajab jesus wow....

I read all 72 posts haha

Now that was a chore and a half to do.

:band:

Now here is the trick and I need honest advise here. I am pretty sure you guys in AUS have been getting the new skyline ( G35) down there. For those that work in shops Like SydneyKid: One of my options for a chassis donor for the rb31 motor is a G35. If I were to say go 4wd the setup will bolt up correct? I did see a 350z with a rb26tt AWD in it fully functional. Was told no extensive modifications were done to it. Could anyone comment on that? Also other vehicles of choice are the following:

LS400

SC300 - Soarer

GS300

Q45 - 1995 + ( they look alot like the chasers hehe)

I was also thinking of a Volvo S60 ( but engine bay restricts that)

Anyone else would like to add some chassis suggestions to the list? I do not want something too old, but yet not something to cheapy looking like a 240z or something like that.

Remember I am living in the states and can't afford an insane skyline. Damn too way over priced over here. I thought of a s13/s14 but I am parting out my current drift machine to pay for this project. Mainly the motor

:elaugh: I was also thinking of a porchse hmmm...

Anyone give me some ideas, but something tells me a G35 will be the winner that or the GS300.

P.S I am to keep this car with motor for te rest of my life. That's why the motor is going to be overbuilt. So as to have more then ample tolerance for the hp and what I will be doing drift, & road course.

If anyone can contribute any pictures please do do.

Thanks

I am at :hippy: with motors.

Hi Daiso, lots of questions;

I have seen a couple of 350Z with RB26's in them but they were 2wd. They are designed for a V6 so just fitting the in line 6 in the engine bay is not easy. It doesn't bolt up to the 350Z gearbiox either. The floor pan, front suspension and engne location would make fitting 4wd very expensive and extensive.

If you are looking at Toyota chassis then you would be better with an engine that simply bolts in and has the turbo/turbos on the right hand side of the engine. Say a 1JZ, 1.5JZ or a 2JZ they bolt straight into the SC300, GS300 and IS300 and numerous Supra models.

We don't as yet get G35 here, they are pretty much the same layout as the 350Z with a V6. So the same problems exist in fitting an inline 6 in them plus they don't have with 4wd. That might come with the new GTR, one day.

I think the S14 240 is the go, the RB20/25/26/30 conversion is common in the US, there are quite a few shops who can supply the kits, engine mounts, radiators etc

My 20 cents worth.

well a z350 jsut ran 7.30 @ 191 mph so there is you best engine base

cheers

Ehh

s13/s14's are not an option here. I know they are easier to use as well as a 350z. But I opted to use only the G35 ( in terms of nissan) for it's style and well virtually I am makeing my own skyline without Altessa system. Since the majority of serious drivers take it off anyways. I am fully aware that useing the Lexus chassis will require custom mounts and a drive shaft. Wireing well thats a given. I am going to make a tad simpler by not going AWD. But still the cars listed are somewhat my options. Another thing I was thinking is audi 2001 +. They have the rounder curves and would look great as a road racer. Sleek and and well sleek. hehehe. The readiator support and firewall will have to be modified slightly but I am confident it will fit. Also takeing into account that the audi motors are V type it will fit. I had a S4 bi - turbo motor and tran which I sold off. and that thing was rahter big compared to the inline 4 or 6 of a nissan.

As you can tell this is going to be a long term project. That's why the motor must be prestine and I am going to pay a pretty penny for it.

I guess its my choice in the end.

Thanks

Daiso

daiso,

it might be a good idea to start a new thread on your topic, you may get a lot more reply's (as the majority of people porbably won't be monitoring this thread because of it's size) and help keep this thread purely about the RB30 conversion

Thanks

Your right, so back to the topic RB30's.

I have read the thread and well I was not really satisfied how the turbo topic was covered. What I am looking for is as high HP I can get but no or almost no lag what so ever. I hate lag, which is why I am decideing on rb30. I want to source our a turbo as my motor is being built. Would anyone like to post their turbo setups and advantages disadvantages? At what rpm are they hitting maximum turbine efficency and what powerout put is being putout?

Please let me know, I am not sure if there is a turbo out there that would be able to max at 700 - 800 at around 5,500 -6000 rpm. Anyone has thoughts. Also not sure if this is practical, but would it be to much to ask the turbo to be daily driveable???

Thanks

You get a bit desensitised to power outputs on here sometimes. I took a friend for a ride in an R34 GTT last week, it has 265 rwkw (about 435 bhp). He is very used to powerful cars, currently he owns an F360 Ferrari and he has had a few Porsches before that. After a few minutes of driving in the R34 he was stunned at how fast it was, he simply had no idea what a Skyline was capable of. I then tried to explain to him how much faster the race R32 GTST was with more than 400 rwkw (650 bhp) and 200 kgs less weight. I don't think he could comprehend it, so I promised when the new RB31DET goes in he can come for a ride.

The point is Daiso, do you have any idea how fast a 700-800 bhp Skyline really is? Then think of it as a 2wd daily driver in the rain, heat, snow (probably not in California), traffic (definitely in California) etc. On the race track, the extra 200 bhp comes in very handy, but I don't think I could ever use it on the road.

If you still want to check out some turbos, pop onto the Turbonetics site, the dual ceramic ball bearing, titanium compressored T66 is the go for a bit over 700 bhp.

Hope that helps :burnout:

Thanks sydneykid.

You absolutely have a valid point there. To be really honest, and hopefully I am not running people thru bush's of confusion here, but reason why I say " daily " is again dependablility. In all practicality the motor will not be driven daily. As you have mentioned 700 - 800 bhp car in traffic, rain etc is just asking for trouble. Especially morning traffic, stop and go... stop and go in a 2 - 3 plate clutch.. I had a hard enough time with my single disk Ogura race clutch for my 340hp sr20det. Again this project is going to be long term and I am deffinantly not going to sell it ever!!! just like I am parting out my 180sx. I want to choose 1 setup and go with it till it dies on me and have to replace it. I don't want to drive.... get use to the power and then spend more money to upgrade a turbo etc when my initial goal was that higher power figure. If I am going to invest such a large amount of capital I want to invest it once or as few as possible after the initial investment. By all means, and I have mentioned this before with sydney kid, I am not going to use the full 900 the motor will be built to tolerate. I always overbuild all of my projects for longevity. Would it be possible to have some " Ideal " turbine graphs posted so I can do a bit research on this myself?

Thanks

Daiso

:rofl:

JNR24 what engine did you have in your R33 before your RB30 conversion?

Damn this was the longest thread I have ever seen.

what do any of you guys think is best for an immediate upgrade in engine power?

I was looking at this website and noticed they had heaps of stuff for Skylines and is this Turbo much different from the RB26DETT one?

http://hioctaneracing.com.au/eshop/product...products_id=366

Yesterday I picked up a VL S2 RB30E bottom end for free.

It was striped down and I found it to be in good condition, even the Nissan bearings were hardly worn.

The girdle looks to be very similar to an RB26 one as SK has said before.

Attached are some pics.

    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
    • You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
