Looking on Spool imports site I see they list a complete RB34 short engine, block, crank and pistons etc etc

Has anyone got one and what do you think of it and the build work done?

btw, for use with RB25/34 road/drag use

cheers

They used to have a video on their site of one a dyno making about 900hp but haven't seen anyone actually post one up here.

Cheers, from what Spool have told me that bottom end is good for 8 - 9k rpm limit

But what head would peeps recommend using between the 2.5 GTST head and the Neo head for a 3.4 conversion?

To make full use of that rev capability I have the option of using my current RB25/30 GTST s1 head with Tomie pon cams but still on hydraulic lifters. That I've been advised (and used) 7.6k as a limit and believe it shouldn't be reved higher?

Or go buy and build it with a neo head and high lift cams to make full use of the bottom ends rev range

26 head is out as none of my ancillaries are going to fit. Any other options other then convert my GTST head to solid ?

atm I am using a T3 bb GT35 but with a 1.06 exhaust housing. If that will now be undersized I don't know? But when it was mapped as a 3.0 it wanting to keep making power past its 7.6k rpm (safe) limit so maybe not?

As for the rev range yes it seemed odd but as they don't know 100% what I will be bolting onto it that's maybe why?

I haven't got a problem with that, more that I am happy I know a safe range ... or max when built

Yes the head needs to be right and be able to run to the bottom ends limit

A GT35 will have epic response on a 3.4L certainly wouldn't be testing the bottom end of the spool kit. Nor would i think it'd warrant a big $$$ head either.

I'd imagine a GT35 falling off around or probably before 7K.

Depending on what exactly your plans are for the car maybe start looking for something like a 6466?

As above I can only repeat what I was told by the dyno operator re it still making power all the way to its redline of 7.6kI

it would have reved on and made more if it wasn't for the hydraulic lifters

btw this is a sunday toy and for occasional drag strip use hence wanting the spec

Sounds like a bit of a greek salad.

Your going to the trouble of selecting a 3.4L for a drag build and then talking about limiting it with the head and turbo.

For drag, RPMs can help with the power up top, turbo needs to run up there and not be restrictive in housing.

Big lift cams and big turbo housing can get you some serious MPH but will sacrifice streetability.

The other thing is rod stroke ratio and piston speeds if your going to rev a 3.4L hard.

Get yourself a RB30, forget about stroking it and go from there.......your not in the zone for a stroker.

25/30, forged bottom end, bit of head work, right cams and turbo and your there without the stroker expense, if it blows its not so much of a money pit and cheap to rebuild/replace.

No I don't want to limit it with turbo or head but just thoughts on what would be the better way to go?

Maybe there isn't? If I stay with a GTST it will cost to get the head converted to solid and new cams

Or if I went neo it will cost again for cams and a head.

Both might end up about the same?

Yes I use the car up the strip but its not going to be an out and out drag engine, as I still drive it as a day to day car (when its not raining lol)

Will see what turns up anyway as neo heads aren't that easy to come by by the looks of it either

Neo head with a shim under conversion is on par with a 26 generally.

Gt35 does not seem big enough to warrant a 3.4

6466 is a great combo for a 3l.

You should make 500kw + (e85) never have to worry about how high your limiter is.

Save the extra from the stroker crank, put it into the head.

Get Rips to ship you a 3.2 engine - he may be able to find you a Neo head as well.

What's involved in doing the shim-under conversion on the Neo head?

Cheers, have decided to go for the neo head so am on the lookout for one now

As for the 3.4 motor its a done deal. Deposits made so the sooner its built and over here the sooner I can get on with it

In the mean time I have my 25/30, turbo and injectors etc etc which I can use to help finance this new build

Will see how it all pans out I guess so no doubt I'll have a few more questions lol

btw, Talking of injectors am I still likely to get away with my 740 nismo s/feed injectors, greddy copy manifold on a Neo?

Or is that impossible to say till its fully speced

Cheers

    • Well, I can recommend the partial AV system translation CD I ordered from Car Audio Workshop in NZ. Whilst it didn't address the date issue, it has conveniently translated on-screen menu items into English, and now allows the GPS-received time to be offset in hours rather than minutes, so I can display Eastern Australian time accurately ( and bump it by another hour when daylight savings starts ).
    • Yuh, if it's 45°C outside, my car is driving in it.
    • I'd be curious to hear more. Otherwise, have you driven a modern x-trail? I wonder how it compares. Here in Australia they are/were popular for rentals and fleet vehicles. I have been in some and my impression was they are bad. But, this may have been very different in the 2000s at a good trim level. Twenty years is plenty of time to make the model worse. I do very much agree with the 2 silver cars in the garage approach. But, not driving because it's too hot would not leave a lot of time in the year for many Australians. I don't think you need to worry too much unless the car has actual issues with overheating. 
    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
    • Thanks for that, hadn’t used my brain enough to think about that.
