nisspeed bulit my mates motor and he is running 30 psi through it.

Rhemac they do alot of engine work for tillbrooks.

There are quite a few more that i can not think of right now, but speak to cubes, black32 or sky30 as they all have well built rb30 motors.

Lewis Enignes is building my RB30/26det drifter. Ported head, h-beam rods, jun crank collar, the works. Were looking for 350rwkw's to start with then once I get a better oil pump well be able to crank it up some more.

Darren is building a couple of RB30's at the moment so nows a good time to contact him about it.

8391 6125,

Cheers,

yea lewis, if not lewis, go willal racing, tested and prooven.

i had my forged engine done by Willall racing and they did a great job but im sorry but willall racing dont build motors anymore because Peter hall their skyline engine guy left a while ago, even still they use Nisspeed 2 do all the their machining of the block n head etc so i would go there and have it done, then they take it and get it tuned at Morpowa which are also great tuners coz they are next door, but Willall still tunes cars by Martin

Known Pete Hall for over 20 years from Adelaide Engine days and he really knows his stuff........he's at Outlaw Speed Shop now.

yeah peter is a great guy and was very helpful and know's wat he's talking about wether its skylines or gen 3 v8's

im thinking of getting chris milton at milton engineering to do mine...recommended highly by a mates dad who builds/restores ferraris etc. Take a look at their website and give them a bell to see what their like for yourself.

Yeh Chris is alright, BUT our saloon car has more grunt down a straight line than his.......LOL and my mates old man built the engine!!

I think Tilbrooks old engine builder(don't mistake that with that tool that used to dyno there back in the day) went to JMS to work for a while and is now at Wheelworx!! You could try and see if Joe wants to get him to build you a motor, not sure if they are doing that there or not, I know they have macines to do it!!

My experience is otherwise.

35pounds seat pressure for a performance turbo 24v nissan motor is apparently really really good. NOT :)

Prior to that they set it up so it was floating all over the joint. 15pounds seat; floated from day one.

umm 70pounds is where u want it. They looked at me with a shocked face.

I've had the head off 3 times to sort out the lack of seat pressure that they should have been able to sort from day one.

Speak to Nisspeed, Lewis or Adelaide engines if you want some one to build your motor with experience under their belt.

Bit of a catch 22 situation. My experience with reconditioning heads is that you keep your seat pressures to a minimum unless your running welltite inserts (or similar). Obviously the higher the revving the higher the seat pressure you'll need but some reconditioners have gone overboard with seat pressures in alloy heads and pounded the seats into the head to the point were they have to be removed and have your head welded. Thus said 15 pounds on an 8000rpm motor will just float the valves.

Thats exactly it SLED, minimum seat pressure that works. Which comes down to experience what does.

The RB26 heads run 50lbs seat pressure standard; the rb25 runs very close to that but uses the heavier hydraulic lifters. As you would know heavier valve train requires more seat/open pressure to control the valves.

Mine being setup so loose because they really didn't have any experience with the rb25 head has cost me a lot of money and what really got up my nose is when I sent it back to be fixed up I was charged quite a lot.

Such is life; given time they will get the know how of what does and doesn't work with the rb25 heads.

Typically its known that ~70lbs of seat pressure with the hydraulic rb25 head works very well.

R32Abuser; if you do get a motor built up by them ensure they restrict the oil delivered to the head.

Without a dry sump setup its really the only way to control the oil being dumped in the head and filling your catch can under constant high rpm as without a decent vac setup the oil cannot return to the sump quick enough.

I run a single 1.5mm up front and blocked rear. Works extremely well.

Don't get me wrong Miltons do awesome work; its just a slight lack of experience with one motor type that left me a little unstuck. They are getting in to the drift scene so no doubt a lot of R&D will be done.

In saying all that there is ALWAYS some one who's had a bad run with a workshop from time to time. ;)

The experience wasn't bad just the outcome which has been frustrating when I had to go else where to seek advice and get the problem finally rectified.

That sucks with the issues you had Cubes, you would think they would have had enough experience in that area.

I never really noticed too many probs with too much oil upstairs until I got my mods done and now it seems to be an issue. I've got to organize an air/oil separator.....too many junk catch cans out there unfortunately and I dont know which way to go at the moment.

Yeah I guess its part of modifying; nothing ever goes smoothly. ;)

The biggest worry with dumping oil in the head is if you track the car. Constant high rpm and the oil isn't able to return to the sump quick enough which ultimately results in oil surge. A lot of the blokes get around it by over filling the sump.

Mine was extremely bad as I have close to 90psi over ~4000rpm ish. after a hard pull on the rollers I could see the oil puddling with the lobes slightly poking out the top of the oil. Restricted the oil down and its now spot on.

I run 2 catch cans one either side down low as its neater than having big hoses winding through the engine bay.

Tomei sell oil restrictors but its a pain in the arse pulling the head off for a $5 part.

Kisin and R32Abuser, it may be worth having a chat to Sean at Boostworx. They have tuned and built a few rb30det's; they also get work done by Jason @ Nisspeed.

Sean is well aware of the oiling issues and has had quite a lot done alot of fiddling to get it right.

Appreciate the advice :thumbsup:

on my holden v8 speedway motors we used to drill a hole under the valley cover into the timing chain area for the oil to drain back thru and tap into the back of the heads and put a return line back to the sump .

i would have expected somelike like miltons to be more clued up than to make seat presure mistakes .

he has been around a long time i used to race agaisnt him at speedway yrs ago

Yeh tell me about it...... In our IPRA car we've chucked a 3SGTE in a RA40 Celica, 3S came out of a Mr2, so in the rear and FWD specs to front founted RWD car, and those engines have a mad lean on them in the Mr2, and we obviously had to straighten it up, Alot of people have had issues with this, as we did early on!!

    • No, I refuse to buy their cheap ass crap! I do need to order a bunch of different nuts/bolts to refill my nut/bolt wall though. Maybe you could go for a walk through Bunnings for me? (Or send me some stuff from your work? )   I really struggle to work out how the US standardised to Metric in what the 70s or 80s, and yet, half a century later, there's been little done to actually bring it into fruition. It truly baffles me    On the whole Fastenal thing, I went reading their site (My god they sell a lot of varied stuff!), and it seems like it really depends what store you're near if you can walk in and just grab a few small things, or if that branch is primarily distribution with only a small window of "counter time" available (if at all). That definitely makes it harder, as move locations and it drastically changes your ability for success   For things like your M6x1.0, if you want to work on your own Skyline, and you also have a "home workshop" I'd recommend setting yourself up a small Nut/Bolt wall/section. It doesn't even need to be big at all. Most things depending on the diameter, will be a specific pitch, like the M6x1, M5x0.7 etc. Bigger bolts is mostly 1.5, except for a small number of things and that will come down to torque. From memory bolts for the brake calipers (and other things that need a lot of torque) will end up being a 1.25mm pitch. Save up a few dollars, and order a range of nuts/bolts. If you want to minimise cost a little, buy something like M6 x 40, and M6x70mm (1mm pitch) in both. In addition, buy yourself an M6x1mm thread chaser. That way you have long bolts that you can cut down to size, and then chase the threads out. Funnily enough, I find what I'd pay here for ordering 5 bolts, I can pay about 50% more and you'll get 100 of them.   If that doesn't quite work out due to space / ability to buy plenty up front, then each time you need some bolts, order 100 of what ever you're getting. Put them in clearly marked containers. Over a few years, you'll acquire plenty of different sizes, and will end up ordering less and less. And the cost for 100 bolts won't be much more than you paid for your 5 you needed to order anyway  Just takes a little planning ahead, by investigating what nuts/bolts you'll need, and ordering them before doing the job.     Edit: If it's also primarily for working on just the Skyline, for some reason my brain is screaming that at some point, either Nissan, Nismo, (Or possibly a third party) was selling a "kit" of every nut and bolt in a Skyline, purely for people restoring/rebuilding. It'd likely be quite expensive, but would give you every/any nut/bolt you need for stock/factory things. I'm not sure if it's still available, or even if it actually fully came to market, it's just something niggling in the back of my brain that you could look into further if that sort of thing interested you? (It might have been for the R32 GTR or something specifically too, and not just any Skyline)
    • 90lb/min @ 20psi is wonderful, not so much of a problem with the G35-1050's compressor efficiency (aside from how bad they roll back at higher pressure ratios).  The issue is more to do with the turbine's flow, which is why I'm not sold on going an even higher flowing compressor with the same turbine.  I'd say go back over Motive DVD's testing of the G35 1050 and Hawkins's comments regarding exhaust back pressure issues with it, I'd need to go back but I have in my head he went to the biggest hotside and ended up sacrificing a lot of spool (so it ended up behaving like a bigger turbo) and still had EMAP issues.  I've heard various other experiences along the lines of that. At this stage at least I rate all I've seen about Xonas (for transparency I've not used one directly, but I have spoke plenty with people who have) to have low exhaust restriction for the response they offer for any given setup - basically they allow the engine to breathe, which is good for the engine and makes making power a lot easier.  You arguably don't have to even push quite the same amount of airflow through an engine to make the same power if you don't have the bum plugged up with exhaust gas struggling to escape the engine due to an underflowing turbine.   In terms of reliability, to be fair I've had great luck with Garrett turbos as well - my GT3076R lasted forever, then I sold it and the next owner had no issues, then that car got sold and it was still going strong last I ever heard about it.  The trick is with the old GT-series turbos the compressors etc were no way near as efficient as what we have these days, it was almost hard to push them into severe overspeed situations without having a boost leak or something - and that is what often starts the failure situation.    In terms of your G35 I'm pretty sure you're running yours within sensible limits, something people with Xonas and Precision turbos aren't often so inclined to do.  The "compressor maps" are "Joe blogs ran 45psi through his 6466 so I can do the same" and built their setup to send it to the moon.  I've seen EMAP and compressor speed data where people have actually set that stuff up on Precisions and Xonas which have been run hard and the comp speed numbers are very very exciting at times - like I've seen 76mm Precisions run at rpm that you ideally shouldn't run a G35 1050 lol.   I know people who have run G-series Garretts hard and hard a failure, then replaced them with Pulsar turbos as a cheap "get it going" stop gap with the intent of doing a proper upgrade when THAT fails... and are still running the same thing.   Like anything, ymmv and it's not always to do with the quality or trustworthiness of said product. I've been provided with a bunch of compressor maps for Turbosmart turbos and will update my list based off that, they could prove to interesting reading and an interesting alternative as well.
    • Just cage it, call it a race car, and then fall in love with the chirp chirps through pit area!   Also, this is coming from someone with a completely locked diff...
    • I still have an old R32R left over from when they were a thing in the early 2000's. It was, for its time, done about right. But its time was 20 years ago.  I did try and update it a while back but it was cruelled by a (recommended) muppet of a tuna who couldnt tell his MAP from his TPS. The original spec was: Power FC, 700cc Sards, Nismo pump, 2860-5's, cams (Basically Poncam A's), Z32 AFM's and a half sorted oiling system. Thereabouts 430rwhp irrespective of what was done. So, yeah, very 1990's. I eventually got sick of it not being very refined and bought a Link G4 PNP with some 1000cc Bosch injectors. This was tuned badly and I put the car in the shed for a few years whilst I sulked and went and did other things. Ive come around to the idea of getting it going again so it has a new gearbox installed and some other minor things in the planning. So my questions are, variously (In the context of keeping the Link) What other sensors should I be running eg It has no wideband on it at the moment, nor fuel pressure. $? Is it worth chucking the old ignition system (ignitors etc) for new ignition coils? $2k? Cam/crank angle sensors? Can keep the aircon? $? Anything else? Sorry to launch another what should I do with my car thread but, you know, what should I do with my car? Random photo for historical context.
    • If you think that's harsh, go experience a KAAZ 🥲 Thoughts and prayers for Dose. I had mine modified by a diff shop to make it less brutal, no idea what they did but it's not as brutal as before. The Asian in me was being tight before and went KAAZ instead of a Nismo, lesson learned.
