"An RB25 would have been better for cruising." Well, when I am cruising down the highway on a trip, I would rather have the fuel mileage. Of course there are occasions when another 75 horsepower would be advantageous. I have often said that stoplight drag racing is childish and immature --- but if a guy pulls up next to you in a BMW, well you just do what you have to do .

My local JDM source just got in stock an R34 front clip, with an RB25DET NEO and a 5 speed. The price is $4000, and I was very tempted. But there are two things putting me off: 1. The R32 front clip I am using cost me $2000 and has 57,000 km on it. 2. The NEO motors are rare here - none of the local tuners has ever worked on one to my knowledge, much less done a swap. I am sticking with Plan A.

We have been so focused on getting this thing put together that we failed to notice something unexpected - there seems to be no adjustments to the caster and camber of the R32 front suspension. What are we missing? Do you just have to buy aftermarket parts?

With our fabrication skills, we can easily make the tension rods adjustable, but the funky angle of the upper control arm complicates the camber issue.

For the past few weeks, Sean has been dividing his time between the Studebaker project and doing some upgrades on a 1968 Mustang convertible that belongs to a friend of mine. We started with the idea of just buying and installing some of the disc brake and power rack kits that are available for the early Mustangs from various sources. But as we looked at the options on line, we kept thinking that they are not cheap, and the quality is certainly no better than the Nissan parts we are using on the Studebaker. Not entirely Skyline related, but some of you might like to see what we have done with a few used Nissan parts - this will be a truly unique Mustang:

Sean has finished the turbo/intercooler plumbing and has been modifying the bumpers for the Studebaker. A lower valance panel was fabricated for the rear end and the bumper was moved in tighter to the body. Both bumpers were reshaped somewhat, and studs were welded inside for the mounting brackets, so there will be no bolt heads visible.

The Infiniti J30 (Nissan Leopard) fuel tank is installed in the trunk, below the rear package shelf. Because of the inevitable effects of gravity, there was only one choice for the fuel filler location. I used a filler cap from a motorcycle. We also converted the hood to a front hinge arrangement to provide better access to the engine compartment. (Don't be confused by what you have been told by those guys who live on that big island off the coast of France - a boot is a type of shoe invented by that famous shoe salesman Wellington, and a bonnet is a type of hat that some ladies wear to keep the sun off.)

Can someone please tell me the year of manufacture of this Skyline? It is a R34 front clip with a rb25NEO motor, currently for sale locally. Total mileage is 95,396 KILOMETERS ( 59,276 MILES)

After months of body work, many coats of primer and hours of block sanding, I finally was ready and took the car to my painter friend. I have painted all my project cars, airplanes, motorcycles etc since 1958, but I never sprayed a pearl paint and I never spent so much time prepping a car for paint. This is as close as I will ever get to a show quality paint job.

Installing the headliner was not much fun, now it is ready for the window and windscreen install. I have been working on the dash, built my own heater using a couple of Skyline heater boxes, some ABS plastic, and the controls from a Mazda RX-7. The Skyline pedal assemlies are installed, used the round pedal pads from the studebaker to maintain some semblance of the original look. The Skyline key switch was adapted to the dash.

My fabricator, Sean , has been finishing the fuel, brake, clutch and power steering plumbing and wiring. The fuel tank is installed, and the filler connected. I painted the engine covers, power steering reservoir and few other bits, and now the engine compartment is complete.

With the headliner in, we were able to install the windscreen and rear windows. These are all installed from the inside, and the rear glass is very tight, not an easy job. I made some terminal strips to facilitate the wiring, ran wires to the rear, lights on the left side and fuel tank on the right side. I made rubber gaskets for the headlights and tail lights, and those are now installed. All the lights work perfectly, hope that bodes well for the fuel injection wiring. The ECU and fuse panel are inside the glove box door. I spent many hours adapting the Skyline instruments into the Studebaker instrument cases. The custom made rear valance panel is installed, so we could then weld on the exhaust tips to fit the cutouts in the valance panel. More photos of all this are now shown on my web site.

I will be keeping that up to date, then post here when the car is running, hopefully in a few weeks.

I hope to get my airplane projects and some airshow photos on the site in the next few months.

The Studebaker has been running very well, excellent brakes and steering, can't say much about the handling until I get some bucket seats - cornering on this very soft bench seat feels like sitting on a beach ball. The RB20 has been only going to 8-9 psi boost, so we investigated and found some boost leaks. With all that sorted I was still getting 9 psi max boost. I have read in several places that 12-13 psi is a safe limit for this ceramic turbine wheel.

I hate paying money to buy something I can easily make in my shop, so I decided to jack up the boost pressure myself. It is obviously not possible to take the wastegate actuator apart and shim the spring, so I just added an external spring, with a clamp on the actuator rod which is adjustable. We set it up on the bench using a spare turbo and adjusted the spring so it opens the wastegate at about 12 psi. We installed it on the car and it goes up smoothly to 12 psi boost and is stable there. I can't measure the power increase, but it definitely has more power and I am now quite happy with the performance.

This is so simple I assume others have done this ????

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
    • There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again? 
    • I haven’t yet cut the chassis, maybe I switch to a reverse flow. I’ve got the Intercooler mounted as I already had it but not cut yet. Might have to speak to an engineer 
    • Yes that’s another issue, I always have a front mount, plus will be turbo plus intake will big hasstle. I’ve been told if it looks stock they’re fine with it by a couple others who have done it ahahaha.    I know @Kinkstaah said the stock gtt airbox is limiting but I might just have to do that to avoid a defect so it atleast looks legit. Or an enclosed pod so it’s hidden away and feed air from the snorkel and below Intercooler holes like kinstaah mentioned. Hmm what to do
