What is the best Head Gasket for the money? Also can a 87mm bore HG work with a normal 2jzge? (unless I'm mistaken, our cars are 85mm stock...)
hey jeff how's the progress on the car?
Thanks

The disadvantage of BB turbos is that they are very expensive to rebuild. Most shops don't even attempt to rebuild the turbo, they just replace the whole center assembly which obviously is not cheap!
Best for the money, I would just go with Cometic and also don't forget to pick up a set of ARP head studs. All aftermarket HG are 87mm bore I believe. It's fine to run it on stock bore. Stock bore is 86mm, a built engine with bored out pistons can increase the bore to 87mm and will raise the engine to approx 3.1L of displacement.

Quick question about the injectors...will a OEM Rx-7 460cc injector be a direct drop in for the 2zjge? (and what year range does that apply for with the rx7) and what do you think of $35 per injector? (rebuilt w/warranty)
Thanks
Thanks

Heres a question.
I'm starting to buy everything I need for the NA-T what should I buy first and where?
Also, what all do i need to buy for the conversion?
I want to be around 400 hp when it's all done, I know mostly what I need but I figured I'd ask before I start buying and buy something wrong :P

Since most of the aftermarket folks have moved on to newer model vehicle, this might be your biggest challenge. My suggestion from the research I've done to date is that you go to Titan Motorsports or MVP Motorsports and search NA Supra applications, 93-98, for conversion to Turbo. I think what you'll find is that for a nicely done EM you're going to pay $800-1,300 for the part but you'll thank yourself if you ever want to run boost high enough to move to the 360+ range.
If you want to PM I'm happy to share what I have.
You also might want to visit The MKIV Supra Owners Club for tips (http://mkivsupra.net/vbb/index.php) or Supra Forums (http://www.supraforums.com/forum/sho...d.php?t=414073). On the Supra forums I dropped you off on a page that shows a lot of the set-ups guys are running for road racing, a lot of them are NA-T set-ups.

Hey man - I think we're in the same spot. I'm in the process of doing a HP/$ comparison and matching that against a cost/benefit analysis on parts to figure out the best direction. From that research, IMO, the first place to start is a strong NA-T exhaust manifold, then the properly matched turbo, then wastegate, etc. so on.

The biggest problem I have is trying to pick the right turbo and where to buy all the parts that also won't kill me price wise (before anyone preaches, yes, I know this project will cost a lot of money. )

So, running a colder plug is great right...why not just put coldest possible plugs in every car out of the factory? Well, the spark plug will foul quickly if the plug is too cold. If it's too hot then it will cause pre-ignition. The heat on the plug helps burn away the carbon deposits which foul the plug. So as you can see, you must find the plugs that are best for your power goals. Generally, you go one heat range colder for each 200hp or so you pass the facotry rating. Most 2JZ guys including myself have good luck running NGK 7 heat range plugs. Some people run 6 range, but thats for extreme power applications(I might have to switch to those soon lol). Anyways, for your car just get a Iridium plug with heat range one step closer than stock and you'll be good to roll. Also, if those platinum plugs haven't been used yet then I recommend you return them and buy Iridium tip plugs instead.

Also, you can use the ebay manifold and intercooler. It works great for low power(under 500-600rwhp) applications. You don't need a serious high dollar manifold until you start exceeding the 800hp+ range. I'm currently running an el-cheapo ebay manifold and I'm about to push around 800hp through it. I'll report back soon on how well it holds up
