Hi guys..

I've just been offered a 70MM Power brand "professional products" Thottle body, and EGR Spacer.

Will a bigger Thottle body actually help my engine, or hinder it?

I've heard of bigger tb's actually dropping performance due to too much air being taken in..

Any help?

Cheers.

Simply, you just don't need a 70mm TB yet. If it is at a good price and you are planning a few mods later on then I guess it won't hurt.. But you really need good heads + intake. Plus, the MAF is only 55mm so there will always be that restriction there too.

I just installed a 70mm MAF, i have explorer manifolds (which aren't bad i've heard) and i wanna do heads, but thats a bit rich atm..

I want to collect little parts as i go, but he's asking around $300 for the TB and EGR spacer. both 70mm. I wanna collect rockers, cam and TB, then heads later..

Is $300 too much for the TB and Spacer?

$300 is very reasonable. Is it polished, or just normal finish? You can get polished ones for not much more than that - not sure what brand they are though.

I have just fitted 70mm throttle body from AU3 XR8, the tickford one with the 70mm mass air meter, it is fitted to a EL2 XR8 with the explorer manifold and it made a big difference, i just thought that buying the 65mm was not worth it so i got the 70mm

going from a 55mm to a 70mm will feel like a big difference, but really the best option for you would be a 65mm...
I went from 65mm to a 70mm tickford one and it made no difference at all...

$300 isn't bad, they are $430 new. As said, 65mm is probably the best option but 70mm is fine too.

it really depends on how far you want to modify your motor, a 65mm would be the best option for mild mods, but if you are considering doing going a bit further with alloy heads, cam ect... a 70mm - 75mm might be the better option.

Whatcha think?

i have the power plus egr block, not the easiest thing to fit as they are made for mustangs, all the intake is on the right hand side, i had to custom make a brace to hold the accelerator cable, delete the egr and you will also have to modify the ball linkage on the t/b aswell to suit the aussie motor, all in all it would be easier to get an au 65mm t/b and egr block(out), the au's didn't have an egr.
