Best bang for your buck aftermarket supra parts

^^^ This is true. But...7mge has 9.2 compression. You can run regular 87 octane under normal conditions, when the outside air temp is below 100*. The knock sensor will let the computer know if your getting any pinging, and it will back down the timing to stop the pinging, which is HP loss.

I've never heard it pinging, no matter what fuel I use.

In the summer it gets over 100* here most days. My a/c is on, day and nite, so I run 89 octane to keep the pinging away, and my timing advanced, thus keeping my HPs up.

I can tell the power difference between 87 and 89. Can't tell any between 89 and 91, so I must not be getting any timing retard with the 89.

BTW...I run my timing at 15*.

Someone should sticky this.

I disagree about the earlier statement about cams. From what I've gathered, the cams in the 7M are robust enough, in both the NA and the Turbo motors, to support high HP.

Besides maintenance issues, this is where I would search for "inexpensive" HP in an NA:

1) Intake
2) Exhaust
3) Header
4) Ignition
5) Fuel
6) Electric Fan
7) Flywheel
8) Underdrive Pulleys
9) Ceramic Coatings
* 50-80 Shot Dry Nitrous setup

This is for going all out:

1) Headwork
2) Cylinder Overbore
3) Rod/Piston Upgrade & Compression Bump
4) Tuning
* 90+ Shot Wet Nitrous setup

Great listing in there! .. It appears I started in the wrong order (?) as I've only so far gotten the 2.5" exhaust, with two resonators and I think no cat-back if that's what I think it is (they don't care for emissions in my country). By the way, anyone knows stock diameter on exhaust?

Cool thing that there are plenty of "cheap" mods that one can do with time. I've been thinking of staying N/A with my car.. I don't have a big need for speed anymore.. just want it to have enough power to make donuts and powerslides and that sort of things. I'd rather not have a turbo on the daily driver, although my previous 2 turbo cars never gave me a problem... but non-turbo's are.... simpler? :P

So intake/header/ignition should be the next few things. I've already found out that OBX is pretty much the only (or at least the best) way with the headers. And K&N is best for intake, although I went to 935motorsports.com and wasn't sure of WHAT exactly I should buy, when I decide to buy what everyone calls "intake". (Can anyone lighten me up a bit here?). And by ignition, I assume that means: good cables, iridium spark plugs, coil blaster and msd? (MSD being that thing that makes the plug discharge more than once, right? I could also use some explination on this).

God bless the forums. Too bad I'm probably the only dominican in here, heh. But I'll make ya guys proud of my Supra! =P

The list I've made is not necessarily meant to be followed in that specific order.

MSD stands for mulitple spark discharge. There are other companies that make similar products. A high powered coil is controlled by a computer allowing for mulitple sparks for several degrees (angle wise) throughout the duration of the spark cycle of each cylinder insuring complete ignition and combustion. This in turn gives more power, easier starts, and usually also translates to better gas mileage.

Yes, when I meant ignition, I meant the whole package. Wires, plugs, cap and rotor (if applicable), a coil, and a multi-spark box.

What brands are good and where's a good place to get them at a reasonable price?

My n/a has plenty of power to get sideways, loop, spin wheels in 2nd gear, whatever you want really lol. MSD is a company, and i think what most people would be referring to is an aftermaket igniton coil, i guess. Also get a new cap and rotor, since the n/a has a distributor.

True, But i know wit my friends camaro, tpi and running 10:1 pistons, on regular gas you never hear a ping or knock or anything, it runs beautiful. its just because the knock sensors and computer are fast/good enough to prevent it. but like you said there is power loss...so it does help to run higher octane if your compression is higher than about 9:1. But my point is (to others) that just because you dont hear the pinging, doesnt mean its not retarding the timing.

what about from 87 to 94 octane, would u notice a difference? Here it doesnt cost much more, and at some stations 90 octane is considered regular :S

[yuuki32]

not sure but unless the engin has a different compression than the JDM one it should be better to run higher octane. they are marked as premium only and premium in japan is about 97 octane at most gas stations.
