The 1UZFE EGR Delete Kit is available for sale here.
Amm? Not meaning to be smart ass but CV's etc are part of transmission..
How quick is the gear change on TKO ?? Mine could be alot better...
Dang! Well it was worth an ask. Also good to here an answer from someone who has already looked into it.
Are you planning on selling these units? I have no welding or fab skills.

TKO600, shouldn't break? Boost control would be good....Autronic can do it i just need to set it up.....i get a bit lazy on the details sometimes

Justen, I do mechanical CAD work all day long. If you get me the info I need to draw it up I would love to help this get into production.

No dyno yet....test dyno is moving so tossing up whether to wait or just use another dyno i know reads about the same.....the risk using another dyno that nay sayers will call foul? anyways,, trap speed improvement indicates good gains...could be as high as 70kw and that was with less boost.
Anyone waiting on emails will have to be patient as our dept is moving offices so i have lost email until at least next Mon.

Just trying to sort out is it longer runners for bottom end torque and short runners for top end ,or the other way round?.Just some conflicting posts in this thread.

only the HARMONICS of the pipes changes with length.
shorter pipe, higher freq harmonic, and the HARMONIC itself is suited to higher rpm
the shorter pipe, however, also has a different x-sectional velocity profile, and for a given dia of pipe, may or may not have issues with the boundary layer choking the flow
if youre intake is sonically choked, then a shorter runner manifold will increase tourque at low and high rpm due to better flow velocity profile.
whether or not the harmonic of the pipe comes into play is an entirely differnt consideration (and one where the long/low short/high internet simplifcation stems from)

Yea generally on same engine size .. The sedan version is shorter than similar engine in truck.. The F series 5.0 / 5.8 for example had heaps longer, higher inlets to gain low rpm torque, than there car version..
Same with Toyota's V6 engines when comparing similar engines ..

Hey guys,
Do any of you know if the lower intake out of an early 2uz would fit the 1uz heads and the 1uz upper intake?
The runners are a bit longer than Justen's design but are not cross flow so I figure a swap might be beneficial.
I know the 2uz's in the first couple of years of Tundra are cast two piece units. The newer 2uz Tundra's are one piece plastic.
Thanks for any thoughts.

No chance KC....everything is different...studs, port angle, etc etc not to mention the variable length intake. One of the 1st things i looked into
SPF replied to your last queries. Currently off work again on doctors orders so no email access....back on thurs
