  1. Dear Sir,

      If you would care to sell the Turbo Hydramatic automatic transmission, please advise if the auto trans would bolt up to my late 50's 283 SBC Engine.

      I am anxious to put a 283 SBC Engine in my 300ZX. I live in western PA and could make arrangements to meet you and pickup trans. I also would consider a transmission adapter to bolt the 283 Chevy engine to the original Nissan 5 speed manual transmission, if you have a source for this type of conversion.  Thank You.

  2. Currently looking for Gutted Plenum for Z31, with passages cut out, with a new top plate, Northwestern PA

    and I have a current plenum in trade. prefer to leave all inlets open, will consider welded closed inlets.

  3. If your goal is only 350 bhp I'd be surprised if you couldn't get that out of the motor that you have with intake/cam/exhaust. I expect my lightly cammed L33 5.3 (better heads, higher compression) to put down somewhere around 325 to the wheels.

    Please guide me in the correct direction. I have a 283 SBC Engine with about 300 HP for installation in my 1987 300ZX with low miles on the body. Are there suppliers available to adapt the Chevy engine to the car body using front engine mounts, and to adapt to the Nissan 5 speed stock transmission.      Or, to provide drive-train adapters if I use the entire Chevy engine and transmission in the 300ZX body.  I have owned the car and the engine components for 10 years and would prefer to purchase new or used/modified components.  Pdfflyer  at Roadrunner.   Thanks ! 

  4.      Like you, I have a Z, and I also acquired a great running 1991 Q45 VH45 engine, and would like to re-build the VH45 engine and install in the Z with a turbo attached.

    I look forward to any details of your conversion which you care to share.

  5. We look forward to your continued documentary on the

           RARE VG30DET Dual Overhead Cam, single Turbo V6

    Who in the US is capable of maintenance on this engines heads, and valves ?

    Can these engines be serviced by the US Nissan Dealers network ? or JDM Sources

        Any specific dealers of which you are aware ?

    There are a few US Contributed videos on YouTube, but no one ever replies with usable information.

       Best kept secret is where you can find an uncut wire harness, and a suitable ECU to couple with these engines.

     Most wire harnesses were cut in Japan ? 

    What are the ECU Numbers available for these VG30DET Engines ?

    Any information    would be appreciated.

  6. I am going to do a vk45 swap on my my 280z. If all goes to plan, I will be making the car AWD. Using a combination of r32 and z32 parts. I have done exstensive work suspension wise to make the car handle the power. Basically made a complete rear subframe and a arms using 300zx knuckles, diff, and coilovers. For the front I am using GTR knuckles and spindles. I have the fabrication part of the rear done, but hopefully finishing up fab work for the front in the next week or two. Once the fab work is done Ill make a thread though. What part of SOCAL do you live in? Im in north orange county.

    I find this to be one fascinating topic.  How far have you progressed in fabricating an AWD car using the 300ZX components coupled with a vk45 swap.

  7. Big Phil,

     

    Nice to talk with someone knowledgeable on the RB engines

    Is the Skyline AWD Trans swappable to fitup the bellhousing mounting of the Skyline trans.

    to a Z31 engine ? I have a lead on a Skyline 5 speed trans obviously.

    I wanted to mount it in a Z31 engine/ body. What is required beyond a custom driveshaft length ?

  8. I tend to agree with DandyZ

    Make sure you have purged the air out of the system.

    Jack up the front of the car and burp the air out with cap off.

    I had a problem with a new Z radiator until the system was cleared of air.

    Only other possibility is a stuck thermostat, and the original radiator may have been fine. Take out the thermostat, give that a try.

    You definitely have an air pocket in there somewhere, and diluting the water with antifreeze has no bearing on the problem.

    All of the vehicles on the NY State Thruway are running antifreeze set to -20 deg and they run all year that way,

    even in the heat of summer. Northerners set the antifreeze to be worst possible case, and go with it 3365 days.

  9. So here's the deal i'm looking for:

    a set of 16"/17" / 18" wheels with a neg or zero offset for a Z31. The reason being is because i need something newer and i need a taller rim that steers okay. Post pictures or send me an email of what you have to sell. thanks. Paul

  10. Please refresh my memory.

    I have searched the archives and still have a question on the ECU Changes on Z31

    Will an '85 ECU work on an '87 car ? Both are turbo cars with a 5 speed, without digital dash, and have original equipment

    as far as AFM, and factory equipment sensors.

    The ECU I am considering is an A18-636 654 which already has a JimWolf Tech upgrade for the injectors

    Will I have to change any other components under the hood ? to use the earlier ECU.

    I distinctly remember, the automatic ECU to be usable in a 5 speed car, although not preferred.

    Is there any other ECU Changes to be concerned about? Regards, and Thank you

  11. I am very interested in dropping a VH45DE into a Z31 1987 300ZX car

    with a 4 speed automatic formerly supplied with the '92 Infinity Q45, swapping the sump pan,

    and getting on the road this year. Turbo on this engine could be added within a year.

    Any inputs desireable.

    PDFFlyer

     

     

     

    I can't even find a harness where I am.

  12. There is a 3rd option to rebuilding with a Turbo addition, versus an RB25DET option,

    and that being the use of an Infinity VH45DE V8 as used in the '90 to '96 Q45, or VH41DE as used in the '97 to 2006 Q45

    which is now an obsolete Infinity rear wheel drive platform. This DOHC VVT engine makes 280 hp without any turbo

    and a great deal more with the correct turbo installed.

    There is considerable more discussion on www.nicoclub.com and www.VH45DET.com and a few conversion pics. Engine mounts are considerably different, and radiator cooling must be re-determined, and hood/ground clearances are a must do effort in this conversion.

    ZMech has posted his VH45DE conversion pics on this HybridZ website. There are several VH45DE videos on Youtube as well.

     

    Heya guys,

    I'm new to z cars, I'm a muscle guy. But I've always had a thing for nissan z cars and the other day I picked up a 85 NA z31 with ~140k miles for 700 bucks.

    The transmission is in good shape the clutch is ok for now and the engine runs, but with what seems to be a bit of a misfire. and theres a terrible exhaust leak.

    My question is, to make decent power would i be better off:

    a. Rebuilding the VG30E and turboing it. or

    b. Buying an RB25DET and swapping it in? (paying a shop to do swap since i'm pretty much lost in the world of imports lol)

    any info on which is better for power, which is cheaper, or just prices in general would be helpful.

  13. The Z31 VG30ET engine required a specific crossmember as compared to the Z31 NA crossmember.

    I'm sure you could fabricate the changes into the crossmember for the Z32 car body.

  14. Does the proposed kit offer any headers to utilize in converting 300ZX to use VK45 Engine?

    or, are there plans to develop such a kit for Z31 cars?

     

    Pdfflyer

     

     

     

    WE are gathering all the parts now will have a kit by summer for the VK56 and then the VK45; have trans adapter, clutch done...

  15. Braap,

    I have a 300ZX Z31 and just bought a 150K mile good running VH45DE Engine, '93 I believe. Thanks for the tip on the NiCO forums having extensive info regarding the Q45 and VH45DE and what years have what options etc. Has anyone come up with a bell housing to bolt to the VH45DE that will bolt to a 5 speed Nissan transmission? Are the exhaust headers custom made, I see where Zmech custom made his. Pass on any info on Nistune, any link would be appreciated

     

    '90-'96 Q came the 4.5L VH45DE. VVT was deleted on the '96 model and was also OBD-II. Contrary to internet myth, the VVT delete did NOT affect the peak HP of that engine. That is a bunch of speculation from those who "think" VVT only affected the upper RPM range and have no data to support their claim. my completely bone stock 150,000 mile '96 Q45 with an old dirty stock air filter put down over 240 HP to the wheels at Torque Freaks through the auto trans, as much to the wheels as some of those false claims state the engine made at the crank! What deleting the VVT did affect was the lower RPM torque. The 96 was just tad bit less torquey below 4000 RPM, barely noticeable seat of the pants, but it was there and could be felt in back to back driving comparison. '90-'95, torque was flat. '96, at 4000 rpm it come on hard and runs the same torque/power curve from there up to redline as the '90-'95.

     

    '97- up to I think it '01 or '02, was the 4.1L VH41DE, VVT was brought back. Stock, the 4.1 was down a little on power compared the 4.5L. Really boils down to if want 4.5L or 4.1L or going to be build some hybrid VH monster as discussed on NiCO. Thanks again, Pdfflyer

  16. There is a Z31 owner in the Baltimore area who reports that he swapped the heads and the intake, but not the Supercharger.

    He stated and added that he opened up the Z31 Exhaust manifold mounting holes slightly,

    Another Z31 owner in the Rochester NY Area swapped the entire VG33E Engine into his Z31, again without the SuperCharger. Search the archives, for a white Z31 in Rochester, NY area for a name.

    Possible, to use Supercharger depending on where the Supercharger is physically located on the engine with respect to the hood.

    Paul

  17. Okay, I'll join in Hi to all my contribution to this comes from my first hybrid was a z31 turbo v6 in a '86 2+2.

    Where are you located ? US ? State ?

     

     

    I would like to do a Q45 either 4.1 or 4.5 liter V8 the motor and gearbox as radiator with the addition of better fans is adequate add a one piece tailshaft and add a gear selector and off you go .

    Here's the story on this: I own an '87 300ZX Turbo with a 5 speed.

    See where this is going? How much ?

    We develop a kit to do the VH45DE. We split the costs and the profits 50/50. Then, once we get 20 people seeing the VH45DE-into-Z31, and half of them buying while the other half asking for LS1-into-Z31 instead, inside of a week, that's all it takes.

    You can guarantee quality mounting parts for the VH45DE for under $100/set. Set the number as 10, and we should be able to do all of that within 2 weeks of 10-hours a day, 5 days a week.

    What do you need $$ to get started ?

  18. A stock 85-87 z31 T3 is easy enough,IIRC the compressor outlets are different.

    The turbo outlet from the compressor to TB pipe is different.

    You may require rubber plumbing from the MAP to the turbo inlet to increase the diameter for the T3, and

    the oil fittings should be exactly the same.

    The easiest manner to swap it is to remove the exhaust manifold from the engine block.

    The exhaust manifold studs are usually the most difficult part of the swap. TIP: Have several replacement studs on hand.

    There is not any increased stress on the engine,

    the same exhaust drives the spool. Depending on the trim of your new turbo, it may induce less stress

    to produce the same HP.

  19. There was a guy using a Z32 Crankshaft in a Z31 motor about 5 years ago.

    His name in Danny Muir and you are going to have to search for him on the Z31 boards,

    Z31.com, RedZ31.com, going back 5 years or so. He lived in eastern southern US, maybe FL, SC, or Georgia, and has built around 6 - 7 performance Z cars using modified parts and high perf turbos. Tell him I recommended his expertise on Z32 cranks usage. Paul

  20. As long as everything was originally Z32, it should go together. I cannot comment on the LSD. Z32 Turbo engine were a shoehorn fit into the frame. Likely install from underneath rather than from above. The original Z32 Turbo cars did have 4 Wheel Steer, not sure if this was an option on Z32 NA. The driver's side motor mount may have to be re-located for a Turbo, as it did on the earlier Z31 model, in order to accomodate a turbo, only the driver's side engine mount changed.

  21. I Realize the Z transmission will not hold up like a T56 or a T5,

    Have any Hybridz Z members coupled a 283 to 305/307 Chevy motor to a stock/ rebuilt Z 5 speed Transmission. 1987 to '89

    Trying to keep my costs down and get the conversion done in order to drive it a few miles this year. In the following years, I plan to build the motor and replace the Nissan 5 speed. Any Sources of an adapter, have searched/ written these Archives here to no avail. No replies offered an adapter source which is current. Read where the legendary Scarab Z used a T5 5 speed from a Camaro,

    Also which 4 speed Automatic transmission is preferred, for power, for economy from which year GM Vehicle? and, which GM Trans fits the trans tunnel the best

  22. The US Shiro edition model was available with the pearl white exterior paint, recaro seats, 5 speed, T25 Turbo, A/c, and no other electric options only in 1988. The Shiro included special white wheels, suspension, the low end heat controls, and various other weight savings. No electric seats or windows, special non-adjustable electric shocks. Other white Z cars were sold in 1988 but there were likely non-turbo models, or 2+2 models.

    The US Shiro models were never available before/ after 1988, about 4,000 were sold.

  23. This has been done quite frequently. Because of the Nissan Turbo position on the drivers side manifold, the LH engine mount is different, as is the (under) frame crossmember to which the engine mounts. The Ecu is quite a different part number. Turbo gages have to be changed in the gage console. A single wire in the wiring harness has to be added. Several persons on Z31.com have accomplished this swap. Some members have even added the turbo gear, exhaust manifold, and blowoff valve to their NA Engines. An intercooler is added in this case to prevent pre-detonation, and you must use high octane gasoline if you are still using the 9 to 1 compression engine.

    The exact diffence between the turbo and non-turbo engines is all about the pistons. The exact same heads are used, and there is an extra fitting on the intake manifold for temperature, I believe. There is a different exh. manifold on the drivers side, and the drivers gages. Other than the Ecu, everything else is pretty much the same engine. The earlier 5 speed transmission will not bolt to the Z31 unless I'm wrong. The NA transmission will bolt to the turbo engine. For further information write to http://www.redz31.com and Jason will direct you to a detailed conversion on his website

  24. I have not done this conversion myself, but have read up on it. The Pathfinder VG33 NA (SOHC) Block will bolt to the original Z31 Heads and Intake manifold. The exhaust manifolds for the original Z31 supposedly line up but the VG33 exh. manifold studs may be a few mm larger in diameter.

    Maybe someone on Z31.com have another Best Practices for this conversion
