Throttle body upgrade

[Datsunreal]

i have reached the limits of the nissan L-jetronic EFI system on my green weapon. it just cant deliver enough fuel for the cam at the top end, ive done all the usual tricks but that flap airflo meter has to go! im going to run a fuel only haltech system with L28ET injectors. the throttle body on the standard injection is only 51mm or so in diameter and could be limiting in the future. does anyone know if RB30 or other throttle bodies bolt on to the L24E manifold? i got one from a CA20 but it was the same size.

240SX Throttles are popular, they are 60mm. And the QH45 Throttle is 90mm. Arizonazcar and pallnet sell spacers so you can use the stock linkage with the 240sx throttle.

Hi,

I just brought a 60mm throttle body of a KA24e,

these can be found on 2.4 liter Pintara T and Ti models,

or in my case a Ford Corsair 2.4 Ghia (89-92), they are re-badged Nissan Pintaras,

they have the same bolt pattern, but you would need something in between, to cover the bulge in the intake manifold.

I've heard the ford 65mm falcon throttle bodies (from the XE/XF type) can be adapted to fit. I think thats what Simon DeGroot has/had in his 240Z/

just updating.

i got an XF chook tin throttle body 65 mm. it looks huge! i hope its not too big for a high revving N/A L24 any thoughts?

You could fill that hole up with epoxy steel (jb weld etc) I used it on a hole in my manifold on the K and it lasted a year getting hot and cold with no problems, mine was used as a daily driver as well.

After doing some research on http://forums.hybridz.org/ it appears that a 1 inch spacer is used with this mod, to allow the use of the original linkages, and the spacer also covers the "egg" shape hole in the intake manifold.

After I get my Megasquirt running, I'll look at fitting my 60mm KA24e throttle body.

ever thought of going 6 throtle bodys my mate does it and its insane

[Datsunreal]

im sticking with the standard TB until i get the Haltech working properly, then ill see about getting a bigger one. same as nigel, get it working then make it better.

I'm still running my original throttle body,

but using the KA24e TPS to connect Megasquirt too, I had to make the little adaptor plate to connect it.

A cheaper way to go ITB may be to get some from a 4AGE 20v from a toyota wrecker?? grafted to a triple webber manifold??

Custom itb would be mega bucks I'd say?
