Hello from XS Engineering

[Z-Tuned]

^^^Well said Eric.

The oiling issue has always been first and foremost on the minds of GTR owners. But as common as it was I didn't hear much of people tracking them anyway. I hit 5 track days last year (yaya short season man) but I'd say I might have been the most active in a Skyline in a large area. The only concern I had was the cooling, since only the rad and stat are upgraded, I haven't installed the oil cooler.

You certainly aren't going to drive wild enough on the street to cause a problem. But what is the issue with the N1 pump?

Igors AutotmotiveForums GTR has had wild problems with oiling resulting in well, you know. But they are going with an Accusump because the car is hitting 1.6-2.0g and other weird Gs in other directions like at Laguna.

Another thing I wanted to clarify for you is that Canadian GT-Rs are not junk. The general standard may be higher in the US cause if you were going to drop $16K for DOT then you obviously had the coin for a good car as well. The lure of $10,000 GT-Rs is too much and some of them are being plated. But lots of great cars are pouring in. N1s, Nismos, Zenitainis, HKS cars ... mine was manhandled a bit by Seigo Yamamoto a Garage-S before I took delivery FWIW.

Yeah, I didn't mean that Canadian GTRs are junk. I was just commenting on what Marke was saying about them. One of these days I'll have to check it out up there.

I know Igor's been having some serious problems with oiling. Our last engine suffered from oil starvation too and we hurt the engine a bit. Expensive mistake....Never again will we have an oil issue because we're going with a dry sump. No more messing around....

^^^ hehe yeah can't you tell I'm just trying to keep the nameplate elevated here. There are some really questionable "Skylines" rolling in that exhibit in shows when they should be out in the parking lot. There is a running joke that Skylines would be real fast at the races if they didn't blow up...not the image some of us were hoping for.

But I guess yeah some people drive 4cyl LX Mustangs and some drive GT500s, its just the way it is.

About the oil pump again...you didn't use N1 or stock so what was in the car before? What is wrong with N1 fo a street/track car?

[XSDAILO]

Well, an N1 pump is basically a stock pump with a slightly higher tension pressure relief spring. So it's a great OEM replacement or for an engine making a little more than 400hp, but anything beyond that you'll want a real oil pump with larger and/or wider gerotors. I personally like the Tomei pump the best, but I've had good success with the HKS and Reimax pumps too.

While we're on the topic of oil pumps... What are your opinions on the Trust and Jun pumps? How do they compare to the HKS, Tomei and Nismo ones? I know they flow more than stock/N1 pumps, but they're also usually cheaper in price than the ones you mentioned.

Thanks,

Here are my thoughts real quick:

1. Oil pump drive in early R32's - people make a much bigger deal about it than it really matters. I don't mean to be making fun of forum people, but I think even forum members will admit that there is a bit too much "monkey see, monkey do" going on. The reality is that unless you are revving the piss out of an engine on a road course where you're always in the 7-8k range, making a ton of horsepower and the harmonics of the crankshaft are getting out of control, or the engine is just a piece of $hit, I would say 95% of the street cars will be fine. The one guy who probably had a cracked pump rotor was drag racing it, road racing it, or tried to do a 25 hour race. Or was dumb enough to build a "built" engine with a stock or N1 oil pump.

2. JDM Rom tunes- Yes, ditch the ROM tuned ECUs from Japan. You will destroy your engines. Japanese ROMs loose the low octane maps (they make all ignition maps the same so the car will run much more consistently) so don't think you're protected in any way. Sell it and get a Power FC or V-Pro. Do NOT get an AEM (unless you want to make a bunch of tech calls and do their R&D for them).

3. 100k engines- It really depends on what you want to do with the engine. Make another 30-40 hp or 300-400? Obviously if you have an engine with 100k and want to make another 300-400whp with it, then you're just a cheap bastard and shouldn't be playing with GT-Rs. If you're not a cheap bastard and want 300-400whp, then yes, you probably should rebuild a 100k engine regardless of health. To make 30-40whp on an engine with 100k shouldn't be a problem if the tuner assesses the engine to be healthy and capable (namely compression, leak down, and visual).

I didn't really know that GT-Rs in Canada are so beat. I guess the open laws over there for imported cars mean that importers will bring over units that cost them less. This means there will be some beat up cars. It's so difficult to get a GTR legit over here that it is expensive. Since its expensive, they will usually be clean cars I guess.

Wow! I really like this guy! That's exactly what I think! word for word!
I'm lucky enough to own one the nicest GTR in Canada, I've been trying to sell her at a price she deserve so that me and my wife can move back to Japan, but no luck so far!
I did put my car on ebay and most of the interest came from American people. I respect that they at least understand the difference between a good GTR and a crappy one!
And about the oil pump drive issue, I can back you up on this one, I had discussed it with my mechanic at Zele/Nismo International, and said the same thing!
Hopefully your posts will open peoples eyes a bit!

We've used both the JUN pump with good sucess. No problems with it. We've used the Trust pump when the customer supplied one once. No problems as far as I know, but that car isn't regularly being raced so I couldn't tell you if there were or will be any problems with it. We've only raced GTRs with the Tomei, HKS, Reimax, and JUN pumps and haven't had any issues with any of them. Its just that when you physically measure the Tomei pump, it's bigger and badder than the others.

If you're going to rebuild an early BNR32 engine, then I'd recommend going with a later BNR32 or BCNR33 or later crank with the longer drive. It just depends on what kind of engine you're trying to build. Glad you agree with me!

Hi Eric, I was just watching Hot Version 85, where they had you squaring off against the Mine's R34 in a Togue Showdown. Congratulations on being featured again by the way, I believe you were in American Touge 2 as well in the R34? In any event, I couldn't piece together what happened to the R32 on race day. Something to do with the engine, but I couldn't quite hear what you said on camera, and my Japanese is rusty at best.

Cheers,

Peter

We hurt the engine the last time attack due to oil starvation under high G loads and didn't know it until that morning at AT3. We beat the Mine's GTR by 3 seconds at the Time Attack and we were pretty sure we would have smoked it at AT3, but I guess we'll never know. There's always next time I guess. You can read more about AT3 at on my blog here:
