    Engine swap possibility (for CA)

    You wouldn't have to weld the center diff on a 4WD tranny, you can use the tranny from a JDM altezza(JDM IS300), It uses the beams 3sge and is rwd, that the tranny you'd want. The biggest downside is the motor is rather heavy for a 4-banger, but it does have a lot of power potential. And you would want the second gen motor(90+), the first gen form the st165 all trac has different heads that nobody makes cams for.

    vg30dett weight vs vh45dett weight

    No manual tranny bolts up to the vh45de, however there are a few adaptor plates out there to fit it to the Z32 tranny and I think theres one for the mk3 supra tranny.

     

    All vh motors had timing chains, the earier U.S. versions (90-93) had a single chain and the later versions and JDM vh41he's had dual chain set ups. The earlier vh45 had sodium filled valves, vtc (through 95, in 96 it couldn't meet emissions and was dropped), and more aggressively tuned ECUs too. So and earlier motor will put out a bit more power than the newer motors (like BRAPPs.) Oh, and the vtc was activated below 4600 rpms, so it doesn't have that much of an affect on the top hp, but gives the older motors two hp peaks.

     

    I may had been guessing too much about weight difference, but I still can't find a verifiable figure for the vg. I still think that the vh is lighter, maybe not by much, but at the least they're about the same weight.

    Alright, I still can't figure it out. I had a mechanic look at and he said that everything mechanically checks out. He changed the water pump because it was leaking (Which must have been why i lost coolant). Right now its hard to get it started and even then it runs rough and won't rev. As for the magnets, they look to be ok based on marks on the pully. If it was thrown off how would I adjust it? And does anyone know anyone in jax, fl that can help?

    Alright, I changed the oil and put coolant in it. I also changed the spark plugs (old ones were black from it running rich). It will rev to 1k and stay there now. The fuel pressure regulator reads about 38. I'm not sure how to check the timing with the coil packs if someone could help out there. I put the uv dye in and theres some small leaks around the bottom of the radiator (at the drain plug and somewhere on the lower hose) but they aren't leaking much at all.

    Tell me more about the overheating. Where both fans running? I know you have no distributor' date=' and if the engine starts then the magnets in the SDS are being read. Have you made any adjustments to the SDS? Is it running in all six cylinders or have you lost a couple? How much boost where you running?

     

    Need more information to help.

    The fans were working and I think all the cylinders were running. I haven't had the car long and I haven't messed with the tuning yet. I'm running 10lbs. of boost. When it was overheating there was alot of steam and coolant was dripping from the frame under the radiator. When I ran the compression check I pulled all of the spark plugs and no water came out. Now the radiator is empty. I'm starting to think that I have two separate problems.

     

    Its still starts and ideals and if i hold down the gas it will slowly rev up after 30 sec or so, so I can move just no power. And I have coil packs.

    I have a 70 240z w/ an 83 l28et running an SDS standalone. It was running fine one night when I was driving home from work doing 45 when I tried to speed up and had no power. I pulled over and it idealed low, I gave it full throttle and nothing for about 30 sec. and then started reving slowly. I could hear boost building up but no power. I was close to home so I tried to limp it back. Then it started to overheat. I popped the hood again and it was steaming and the radiator was wistling like a tea kettle.

    I thought it was the head gasket so I ran a compression check, and it all turned out good. Has anyone had anything like this? Is something other than the head gasket rob power and loose coolant or do I have 2 separate problems?

     

    Thanks.
