2JZ-GE torque dead spot

[CrUZida]

Lets hope no pesky high powered 1UZ's turn up!

I've heard rumours that Damien is coming, but I haven't heard him say it himself...

[gianttomato]

Must build monster engine.

2JZ No shit?

nah, damien says he wants to come - last dyno day where he stands a chance for 4.0L NA horsepower trophy

Would you be interested in sharing what pipe sizes and lengths you used on this set of headers, They sure have open up the top end with no Dyno measurable drop in low RPM power. I'd be very interested to know what size primary and secondary's you used and if you kept the factory poprt pairing. ie 1-2-3 and 4-5-6.

Rod, Port pairing was kept as per factory ie 1-2-3 and 4-5-6. Primary was mandrel bent 1 1/2" into 2" secondary then 2 1/4" at the collecter thru 4" high flow cat and 2 1/4" exhaust with resonator and straight thru box. Will get back to you with lengths.

Do you have the same steering rack limitations in the crown as the MA61?

[ViPeR_NiPPleX]

i eagerly await primary/secondary lengths! I would guess 150rwkw would be the rough limit of an unopened motor.

Wayne,

Mate my Stearing box is deffinatly a PITA. I had to use a 1JZ-GE Exhaust manifold as the stock 2JZ-GE manifolds would not quite clear.

This pic sums it up pretty well


I actually already have the flanges cut for a set of Custom JMR pipes but the 1JZ-GE manifold got me out of trouble and I just have not had them done yet.

That's pretty much what I have, although I only have a 3" high flow cat have the 2 1/4" exhaust resonator and a 3" cannon

The limitation is because its a steering BOX, not rack and pinion.

MA61's are racks so they will have different limitations, but from what ive seen factory exhausts (at least for N/A) clear the steering column.

[1983supra]

In an MA61 the off the shelf headers like Xerd and Tune Agent won't clear the steering column and alterations are not an option, hence the need to fabricate a custom set.

[gianttomato]

Steering box is a major PITA. Only way out is custom or 1JZGE exhaust manifold.

Or retrofit a steering rack eh

You mean futuro-fit

[gianttomato]

Yep, you could do that too!
