Couple of questions that I could not find the answer to:

[Pharnhyte]

First I plan on running a GT35 turbo in the near future after I take a run at the fastest stock twin 1jz title, but I have a couple questions though

1. Max Revs on the 1jz stock everything? I have mine currently set to 8k, the 1jz revs higher then the 2jz, and some of those guys rev even higher on completely stock heads

2. 1JZ factory pistons- are they forged or cast, I cant find the definite answer anywhere, I have read that the 1jz ones were forged and the 2jz ones cast. I want to know for durability reasons.

3. Injectors- 440's drop in 550's need a resistor pack, what about RX7 550's they are supposed to drop in to, does this mean I wont have to rewire anything, I can just put them in, and clip them up?

4. My car idles great, with my stinger, but why does my exhaust burble and pop every so often? I changed the plugs and gapped them correctly.

I plan on having a 11 second DD MK3 rather soon (600 miles a week), and I want it to be as street able as possible, with little to no sacrifices.


Thanks

Steve

1. It all depends on your boost levels. The more boost you're running, the more you're going to start pushing valves open. I wouldn't suggest anything above 8k on stock springs. You will probably find as you start pushing 20+ psi, that you'll be floating even at that rpm.

2. Unless someone has figured out how to forge a piston with internal channels, both the 1JZ and 2JZ pistons are cast. They have an oil passage within them for piston cooling that the oil squirter squirts into.

3. Are RX-7 injecrtors side feed? If you're looking for drop-ins, Denso (who make the stock injectors) make high-impedance side feeds up to 800cc. www.horsepowerfreaks.com is probably the easiest place to get them.

4. What condition are your coil packs, and coil pack connectors?

Hey thanks, I am not sure what kind of injectors the RX-7 ones are, but I will check out the ones you mentioned and Sard ones.

I am also not sure of the condition of my coil packs, I changed my plugs the other week and they looked great, and my car does not miss or anything, so I am ASSUMING that they are in decent shape.

I haven't seen any side feed rx7 injectors.

FD rx7 injectors are side feed
