Re: ITB Conversion on 16 valve 4AGE truly? maybe i really should obtain a new 1 then? presently i get about seven.5L/100km for my very normal ae92 SX? (roughly 450km's involving gas lights) i havn't experienced mine plugged in for over 6 months considering that redoing the exhaust prior to xmas! (snapped it off)
I also modified the stock 16v throttle bodies ISCV, plated the back and included a brass barb. and mounted it.
The Silvertop engine featured a little recesses / shallow bevels main into all sides with the cam bucket recesses. This is often to aid Along with the oiling with the bucket and supplies further clearance for taller cam lobes. Inside the Blacktop’s these had been substantial increased.
I took the initial silvertop manifold and hacked the crap outside of it, I Slash the whole ISCV ports off the best and began rounding the runners until finally I received to this.
Im thinking about dropping the 4A-C and wanted to understand what your experiance was with Every single of your 4AGE engines:
i don't forget getting a picture of a boost gauge i attached into the vacuum block, I am going to check if i can discover it as i are unable to recall what it examine, And that i also throew a mates extensive band logger on there to check AFR's and MAP. i have a few screen photographs of aspect throttle, and WOT.
These intakes are engineered for top Improve ranges and high engine speeds within the get-go! All Weldspeed consumption manifold runner bases are precision CNC machined from 6061-T6 billet aluminium with integrated bell mouths.
due to the fact I've a bigport I stuffed in the spaces to seal the ingestion flange. Just implies I've a step on the inside.
This can be a 20V engine With all the cam-belt include removed. Seen could be the left hand facet pulley that's the VVT gear.
Whilst assisting in restoring and modifying non-conforming equipment, you'll execute all examination with nominal instruction. You may give complex assist over the small business although complying with HS&E guidelines.
With no VVT operational there should be a substantial reduction during the mid assortment ability. If there isn’t a obvious reduction then it’s remarkably likely that the VVT pulley is not useful and needs substitution.
I was typing as well fast and considering much more CHP on the NA determine but did not catch it. a hundred and eighty WHP is stepping into territory that is a great bit more expensive and fewer functional.
Things which I would not look at Definitely essential but a good idea. Outsized valves. Personalized header created for your Construct and RPM objectives.
All ECU’s use various sensors to find out load. Nevertheless the tactic employed may differ amongst engines as the Silvertop works by more info using a simple Vane form airflow meter while the Blacktop takes advantage of a more advanced vacuum (MAP) and throttle position (TPS) for much larger throttle openings exactly where there is not any vacuum.
