haha, you had to pick that video?
that would be my car. And it's not even close to being any good at a drag event.
The diff mounts were bent, and so there was not traction but only found out when they broke at another event. Still ran a 12.7 @ 127Mph, slower than my best time of a 12.3 @ 110 with my old engine.
A 7A build is not as hard as it seems. 99% of my engine are toyota parts.
Still on standard 4AGZE pistons, Standard head and cams,
Only parts special in there is the con-rods, and thats only for reliability.
325KW at 20psi.
I would chose what I have over an SR20DET anyday, as the only one that I have races against that have been quicker have not been reliable.
I run the W series of gearboxes. At 18psi thay will last for a seasons racing, but at 20psi, the dont last one race weekend. I fitted a kit to mine as I dont like R154's etc as they change like a truck,
and this gave me the strength reliability and closer ratio's.
Here for a link for those interested in the gearbox.
do it man, build a big ass 4ag, but you will have no power before 4500-5000 rpm like none so be prepared for mass amounts of clutch kicks or just keeping it singing above 5k.
300kw is atleast 20psi and atleast 8ooorpm on pump fuel, so you need everything to accommodate that.
dx20vt
did you change your ratio's, first gear is poinltess in the 58's. ?

This is why
11,000rpm burnout anyone
doms rigolis ex wifes car
There is an issue of zoom with backyarders car, quite a piece of engineering, cunt to work on though.
Yeah,
1st is now way higher.
Shift point from 1st to 2nd gear is now between 90 to 100Kmh
sweet, thats great. Ill email GHB.com about a gear set .
ill prolly drop you a few pm's aswell about ratios.
cheers.
I had trouble with the high first gear at the start, with the std ratio's I could keep up with the Evo's off the start line when i got the start right,
and with the new box it took me a while to figure out how to launch it again. Just took another 1000rpm and a slight ride on the clutch for the first 1/4 sec, and when i got it right it now takes off as well or better than it used to.
Tell GHB I told you about the box if you contact them and and will tell you all you want to know and much more.
ok no probs,
yeh your new gear set would be similar to taking off in 2nd with the standard 58 gear set and i can take of in 2nd anyway in traffic.
which is what i was going to do at the drags, (launch in 2nd) but im scared of stripping teeth (ive only just rebuilt the box aswell)
ill give ghb a call and go from there.
as im leaning more towards the drags, i was actually going to put a 4 speed jatco in, but if i can get a long 1st gear im set, as i cross the line in 4th gear and rev limiter, sometimes i had to shift into 5th so if i play with ratio's it will be perfect for the 1/4 and some circuit work.
cheers man.
One of the guys at TAFE who does mainly dyno tuning, has a 2J at the moment stock bottem end and its handly 960 something (when i saw him last week)
