1GGZE - good base for strong NA motor?

[oldcorollas]

totally losing velocity?

[gianttomato]

they look like OER

you are looking at $2K to $3K or over for a kit.

Many 6 cylinder kits available in Australia. Hardest bit would be to make up a manifold to bolt them to. I'll be honest, 48mm would be overkill - 45 would be adequate.

GT what throttles did you use on the 2JZ? EFIHardware?

[Johnzoku]

from that article (referring to ITBs)
that sounds like such crap. throttle size has near nothing to do with torque in th low end, and it only influence on tourque in the high end is if theyre too small to accomodate all potential flow

but i guess the same could but said about potential flow at the lower end of the rev range. you make the intake to large and the air that enters the throttles and into the head is greater than the engine requires untill the revs get higher causing it to bog down and not produce as much torque potentially.

tweakit.net in australia have two different kits available for 1800 and 2200

the 2200 one is to suit tripple doec weber manifolds.

and this ones just make it up as you go.

but then again finding some GTR or ae101 ITBs might work out alot cheeper than buying a kit like this and then building manifolds on top of that.

altho, these look pretty tempting

thats incorrect thinking. throttles dont push air in, and engine sucks it in. it doesnt care what size throttle there is.

tuning comes from port length and dia

throttle is exactly that a thing that 'throttles' the flow down the ports

[gianttomato]

Takai, secondhand Motec ones.....don't think they make them anymore.

some rb26 throttles mebbe? look cheapish

[oldcorollas]

LOL

$500 is cheap? if they were $50 you might consider bidding
($100-150 is normal depending on condition)

[ill-minded]

by cheapish, i meant cheaper than the previously mentioned sets

the second link is at $250 with all the extra crap with it

[oldcorollas]

heh heh, relatively cheap...

yeah, throw all that extra crap out

hmm, i have 3 sets of ST TB's i'm not planning to use.. just cbf putting them in classifieds

another 6cyl kiddie out there keen?

[oldcorollas]

does the 1J have the injectors in the head?
if so, surely there is a webber manifold somewhere.. then get some dead carbs and use them.. should be cheap?

[gianttomato]

There's actually a mob that use ST ITBs on JZs - they make a manifold for them too. There's a pic of a VVTi 1JZ with them all nicely set up too. Have link somewhere.

Why don't you just buy a VVTi 1JZ and do that? They come with beautiful headers too. Would absolutely shit all over a 1G.

The pop up on ebay occasionally - one sold on there last week for $500.

ahh thats fair enough, i always saw it as something like sucking a drink through a straw and a... larger dia. straw , harder to drink with the larger straw than the smaller one till theres more force behind it to draw it in. like throwing alot of wood on a small fire and expecting it to all burn at once.

but i guess that only counts if there no head work done to accomadate the increased volume coming into the head.

another 6cyl kiddie out there keen?

im rather interested if you still got them, might send ya a PM.
