How many guys would be interested in a custom intake manifold for your turbo/NOS/NA SR20DE(T)'s? There are two stages.
The first that I have on my car has internal velocity stacks (that are raised off of the plenum's floor), tapered runners and a large plenum. My manifold was also port matched to my intake runners. It changed the characteristic of my mid range and top end substantially. I would recommend this one for those with the T04E/T3 and larger turbo's or those spraying over 100shot of NOS. (Stage II)
The second unit is similiar, but instead of internal velocity stacks it incorporates radiused velocity stacks. This would be perfect for those with the T25-T28 turbo/NOS from 50-80 shot and NA engines with major bolt ons. (Stage I)
If any interest is shown, I'll post the pics on this site. The prices for both are $800 for Stage II and $550 for Stage I.
The units are available for all SR20's 91-99. I have cores for the 91-93 high port motor. You will have to either send in your core or be charged a core charge for 94-99 low port motors.
