5afe throttle body upgrade

[produb405]

Assalamu Alaikum, hey guys,
Has anyone tried the 4afe and 7afe throttle bodies on 5afe? as the stock 5afe throttle body is very restrictive,its only 45mm whereas 4afe has 55-60mm throttle body (correct me if wrong) don't know about 7a i think it'll be the same,but if intake manifold is properly ported with head a throttle body upgrade will be a great step, just wanted to ask!

Bro @Hassan1991 knows probably.

[Hassan1991]

@crystalways3 thanks
4afe has 50mm throttle body 4age has 55mm throttle body...don't know about 7afe but surely it will be bigger then 5afe....
intake manifold will not fit i read somewhere and also had seen pictures of 4afe and 7afe intake manifold they both are different injectors position are different in 7afe injectors are fitted to the intake manifold while in 4afe/5afe they fits to the head.....
yes it would be great throttle body of 7afe would fit on 4afe so it should fit on 5afe also change the injectors.
After market throttle bodies are available also search them....

Really? Aftermarket throttle bodies? Where can u find them? And thanks for your precious time.

[produb405]

And with the manifold i meant to port and polish the existing one.

Is 2nzfe and 1nzfe throttle body different?

[Hassan1991]

Never mention
yes widely available....
also available on pakwheels store...
you may also need to upgrade fuel pump.

[produb405]

Right! Thanks alot brother

[Hassan1991]

it might fit's....same series means parts are replaceable but the problem with these engines are that they have many different electronics...so you have to check both thoroughly.

[Hassan1991]

your welcome

Also brother would a nice set of newer injectors help? ive heard they have better spray pattern and average will not be affected because ecu controls it better.

[Hassan1991]

yep i suggested you before.
that's called duty cycle of injectors.
i tell you setup...change injectors,throttle body,fbr,fuel pump,maf sensor, and headers (measurements of these items depends upon how much extreme you want to go)....you will get significant increase in hp.

[produb405]

A series have map sensors no mav sensors right?and explain fbr pls?

[Hassan1991]

yes sorry map (maf keh keh ka usi ki adat pr gae ) and that's fpr( fuel pressure regulator)

[produb405]

Cant find aftermarket TBs in pakwheels store or any other

[Hassan1991]

I had searched now 70mm throttle body is available last i remember 55mm throttle body was available......probably sold.

[produb405]

those 70mm and 90mm are big probably for jz's.

[produb405]

Yeah, i doubt they wouldn't even fit this tiny 5a

[Hassan1991]

fitting is not a issue actually it will be useless/unstable.
