The AMS EVO VIII/IX F1-I Intake Manifold was designed to outperform every 4G63 manifold available including our own VSR. We referenced many modern design examples and engineering studies to bring you the best intake manifold ever made for the EVO VIII/IX.
The New AMS EVO 7-9 V-Band Turbo Kit produces unmatched power and spool and is simply the most durable kit on the market making everything else on the market obsolete!
What gear oil should I use? There are several gear oils that will work depending on horsepower or intended use. For most transmissions we recommend Redline MT90 or Pennzoil Synchromesh. For drag use or high horsepower cars please contact us. Please let us know if you need any Redline gear oil.
Is there a break in period? We recommend driving easy for the first few hundred miles to allow the gears and synchros to bed in. It is normal for the trans to be stiff for the first few hundred miles.
My car is hard to put in gear or the car must be in gear before I start it? This is very common when the clutch is not releasing. Most often while having the trans rebuilt the clutch is replaced. Installing an upgraded clutch requires more clutch pedal travel and needs to be readjusted and worn parts replaced. We recommend a new clutch fork, pivot ball, OEM or ACT throwout bearing and a braided stainless clutch line.
After my rebuild I can't get my car into reverse but will go into 1st through 5th? The most common problem is that the reverse light switch is over tightened or missing the washer underneath the switch. Simply remove the switch and replace the washer.
Do you sell complete rebuild kits? We do not sell complete rebuild kits. There are changes made to almost every year trans. There are different shift rails, gear sizes, gear tooth profiles etc. and it would not be possible to make up a kit.
