I put eibach on mine and had the same or worse results and added two spacers per spring and they still suck. The shop that put them on threw the stockers away. Unfortunately no one makes a stock level spring with better spring rates.
What gap are you running on the coppers? According to NGK's website the NGK Iridiums as well as all the plugs for a 2JZGTE
(1JZGTE Swappable)are pre-gapped to .044. If you gapped the coppers to that then there is your problem, its way too much. Try a gap of .028 and see how it runs under...

Then see if it will run.
Ok, since you bought it locally then there probably isn't a part number. A generic manifold by HKS would be reasonably priced which is what I would want. Some of the prices ive seen are way too pricey.
The ecu will store the codes, just jumper te1 and e1 as stated here and count the flashes to get the codes.

Oxygen sensor will help on the mileage if you havn't changed it for awhile and might give it more pep.
My mileage when I was NA was horrible, between 14-18 mpg and my top end suffered and 0-60 was 10 seconds plus. I boiled it down to the differential was from a later model turbo, like the...
Side tank rads are the norm for BMW's of which I have a 750il with the filler elevated on the firewall. I suppose the stock rads on them are also dual pass, it makes sense from the design but with the sidetanks on those rads you would have to fab mounts to install in a mkIII and reroute the...
I bought stock 89+ mounts from the dealer and will have them checked when I get it on the road tonight. The Fan clutch Im running now is the same size as the LS400, just stiffer from a heavier silicone I would guess. I run the LS400 in the winter. I'm wondering if the blade just failed from the...
The fan was less than a year old but not original toyota. It didn't have any cracks at all, the cluth is from a landcruiser pick up and is extremely stiff. I can't validate about it locking up.
Just put on a shroud again, must be my 5th one with the Koyorad and on the way home made the decision to not run with the shroud anymore. As I rounded a corner, I gunned it in second and after hearing a large bang @ around 6000 RPM and getting sprayed with debris from the front and from under...
Then fill up your Supra and write down the starting mileage when you fill up and subtract it from the next fill up, write down how many gallons when you fill up and divide by the miles driven.
How old is your O2 sensor?
