Sorry to sound like an idiot. But what exactly is the advantage of using a custom oil pan? And at what point of modification would you need one? Lastly, could it be installed with the motor in the car?

John, How does the hood you describe compare too the CF hood that motorsport just started selling? I believe There's is complete for $700-750. Is that the normal price for CF hoods? Seems pricey. Is the weight loss (time gains) really that singnificant or is just another look cool and trendy while getting some performance gain as a benefit?

Buying a 260z in CA is not desirable because of the smog laws when doing a motor swap. '1973 is the cutoff year am I correct? I wonder if you bought a 260z that was made in late 1973 if you would be ok.

Hey JeffP, I was curious what was the most power you could safely get at 91 octane with that setup. I'm guessing you used C16 at 20 lbs of boost.

The owner of Alt Z in Huntington beach has dropped an Rb25det in his 240 and made motor mounts for it. I went by and saw it as I pondered the same swap. Call him up if you're serious and he may be able to give you a few tips. 240 hoke you're right. Lots of RB26 info but not much 25. I guess most people aren't much in favor of the rb25 motor.

Hey that would be great. I just bought a new grill so its on! I lived in newport for 5 five years. Wish I had known there was a z meet in huntington. I'll come down to the next meet on the 10nth and see what we can get together. Let me know when's a good time to work on the car. I'll have the barbeque and tools ready. Thanks a lot

Well, I've actually done a lot of the work myself under mechanical supervision, including, taking out the first motor and sticking the second one in. I did the simple bolt on stuff like intake, dizzy, turbo, exhaust manifold, and I can put the cooling together. But I've never touched a FI system before, and basically figured out how the injectors and fuel rail went on pretty easy. Next step is to figure out the FPR, fuel pump, and then ignition, then wiring. I'm sure I can figure it all out, and just scared of messing something up and flushing thousands down the toilet. But it's gotta get done. Not doing any good sitting in the driveway.

Hey I was wondering if anyone here was part of the group z club that meets in buena park next thursday at fuddruckers. My mechanic buddies have abandoned me on my project with about a 2-4 days left of work to do, for someone who knows what their doing. Anyway, I'm pretty much a rock when it comes to putting a car together. I have the motor/trans in, intake, injectors, exhaust manifold/turbo bolted up. What I have left is wiring (which luckily is all labeled) ignition, fuel system, cooling, and gauges to hook up (which I have 0 knowledge about) but I figured if I saw someone else's swap and took a whole bunch of really good pictures, along with the manuals I might be able to finish the thing by myself. So if any turbo guys live locally, maybe I could pay a visit to see your car. I figure if I do a little at a time I could have the car running by October. BTW, I may be asking some incredibly simple minded question as far as mechanics go on this board. I will further exhaust my research before asking them but please bare with me as this is the first car I have ever worked on in my life. Everyone's been a great help so far. I appreciate all the help.

I've never messed with wiring the ignition on the car (or much else for that matter) and my knowledgeable friends have abandoned me on this project so please forgive my ignorance. Ok, so I'm using a Z31 turbo coil and HKS twin power. When reading the instructions for the twin power it seemed that all the wiring comes from the twin power and connects to the coil. Is this correct? Or is there additional wiring that is supposed to be with the coil itself that I need to find? If so I suppose I will take a trip the JY and check it out. If anyone has a similar setup w/ some pics, I would be happy to see them. Thanks.

Cronic what setup are u running engine management-wise and what type bov are you using?

Do any of you know off the top of your head, what size the bolt is that screws the injectors into the intake? (280z).

Same thing happened to me two weeks ago. I just bought a tap from the local hardware store and rethreaded it. Took about 5 min. Seems like noone carried the right size in stock though. I had to get it special ordered.

Perfect. Thanks a lot! Great info on your site as well.

Ok, I might get flamed for asking for this, but............ I have the chilton's manual for my 240z, however I'm doing a turbo conversion, and was wondering if anyone had the hayne's/chilton for the the 81-83zxt. I just need the page with the wiring diagram, and didn't feel like paying for an extra book for the one page if anyone had a scan of it that they could post. I know its being cheap but budgets tight. If noone can I suppose I'll buy another book for the page. If someone could though, I'd greatly appreciate it. Thanks

cygnusx1, Is that kit specific to the Zcar? $250 sounds like a good price. Are you saying that with a little hacking the kit just hooks up? Is there any advantage of piecing a mandrel bent kit together opposed to using this one? Who is the retailer of this kit on Ebay? I'm probably going to start intercooling in a few weeks and this kit looks pretty good. Thanks BTW, slow n rusty, do you think the owners of those cars would mind you emailing me those pics? That would be much appreciated. Thanks

My friend and I are about ready to start the wiring on my project 240z turbo conversion. My buddy (who is much more mechanically inclined than I) said that we need to drill a hole through the firewall and run the harness through there. My question is, is there any specific spot that is recommended for drilling the hole? And is there any place recommended against? There is no current spot that already exist to run it through as far as I can see. Thanks for the help.

Ok my P90 head has been ported and polished pretty extensively, and I wanted to open up the intake runners to get more flow. I cut out the gasket with a dremel and matched it tp the intake ports. I figured I could take the gasket and inake manifold to any machine shop and they would be able to port it for me, but noone seems to want to do it. I called an import shop and they said that they had to have the head which is on the block so that's out of the question. I have a dremel at home. Is this something simple I could just do by myself? When porting the intake runners, should I just port at the opening? How far in should I go?

I'm using the greddy type R bov rick. What would you suggest with that system?

Interesting. Does anyone else attest to this? I do have a pretty good intercooler. Its a large HPI model. I would like to vent but if recirculating will give better boost response then perhaps that is the way to go. I have the Greddy type R, which I don't think makes as cool as sound as the type S does anyway, so no use in sacrificing performance for sound as I got a pretty big turbo which I'm hoping won't lag too much as it is. I guess with a full t4, any method to fight lag is the way to go. So recirculation it is.

Hey I just bought an Aeromotive adj FPR for only $129 at Suprastore.com. That was the best deal I've seen out there so far. Anyone who's shopping for one should check it out.

Mine is unsprung then. The rest of you who mentioned 6 puck not being that bad, were you speaking of sprung or unsprung. I'm just trying to get an idea of how streetable my car will be. Bastaad is yours similar to mine or a street disc?

Sorry I'll read it again and look.

John If I follow ur advice will this protect the thrust bearings and crank? or will it wear them out regardless? If so I may just get another clutch though I hate to shell out that kind of money

Should I be using the 280zx OEM 02 sensor or the Z31's? I read through the post and it didn't mention it. Thanks

How do I tell if its sprung or unsprung?
