Certainly wouldn't expect hp gains but the difference in how she drives now is noticeble and the sound is just awesome compared to before, for autocross I think this is right on as your not doing high rpm driving its lots of sharp little corners and that is where the 1nzfe was weakest having that dead spot in the throttle.

After I get a set of exhaust headers made I will look at a cam regrind from Franklin cams here in auckland, they like messing with toyotas and they have done them before as we use the 1nzfe as a jetboat engine here a lot.

Excuse me? I wanna see this, that sounds awesome. The 1NZ-FE doesn't get the love it deserves in North America.

Theres a company here that specilizes turning them into jet boat engines, they are light wight, reliable and have plenty of torue for the job being designed for a cvt transmission they are perfect for jet boating. https://www.youtube.com/watch?v=mkyk9MPCe-M

have to cut 1 bolt (knock sensor bolt I believe), and cut some coolant line and reroute the line

Nice so the bolt i didnt know I had to move and the hose I had realized was going to need modified, Right now im pretty happy with how the long set up is performing but will in the future try that, did you notice any difference?

in real world driving, I'm not noticing any differences

but on dyno, my peak torque shifts 300rpm higher

with stock manifold, the torque drop 25% between peak torque and torque at rev limiter

with RS manifold, the torque drop 19% between peak torque and torque and limiter

Fair enough Im liking how mine runs now with the longer manifold, but may still change it up at some point.

Need to dyno my car to find out and won't do that till i have a tune for it.

Going to get a trd cap and leave it upside down just for remcafe! lmfao

put the extenders on the stock intake...

It is! Its crazy torque down low now with the other mods Ive done, very very easy to loose traction now in 2nd and in the wet in most gears lol.

I haven't been active for a while because the car currently is just damn fun to drive, the Throttle body change, intake runner spacer, intake tube and airbox mod are just working so damn well. The car has no dead spot any more and will DURTTTTT all the way from 1.8krpm..give her the beans and it lights up till red line. With only 6400rpm max it feels like I never get off the torque curve. I dont think I will change the manifold to the shorter one as currently she destroys the tires in 1st and 2nd gear and feels like you are actually driving a hot hatch.

yes yes we need info and pics..its hard to fathom such a tiny engine being used for that
jetboats here are typicaly heavily boosted 4s v6s and big v8s
