throttle body ???

[86gter]

its me with more questions.
can i put a 70mm throttle body and egr spacer on with the 19lb injectors and speed density setup. i am not switching over to mass air yet.

i have a stock 86 motor and need to know

1) is this worth doin ?
2) what else i need to change

I don't think it would be worth it. Your best bet (and cheap too) with a stock 86 is an 87+ upper and TB. 70mm is going to be way too much with stock heads and cam.

Yes you can just do the swap, should need anything else. One thing to keep in mind is the intake is just as restrictive, the 86 was the worst piece! You wont gain as much with the stock intake, and if you wanted to use a 65mm it would actually keep the velocity of air a little higher going into the motor.

i already aquired an 87+ upper just need to get the lower from him.
and what throttle body do i use with that setup cause i also have a 60mm t/b

[wacostang]

i believe stock is 58, so 60 isnt much od an upgrade. A 65 would flow a little better, little better throtle response, and can be had for $125 new. Its up to you wether a few extra ponies are worth the money.
Also if you plan on future mods you might as well upgrade now.

yeah i guess thats what i should do is get the 65 then and be all setup correctly


thanks

I am running a 70mm BBK/Edlebrock throttle body, EGR and a 89' upper intake.
Car was much more responsive and runs just fine. I am also running a o/r hpipe as well.

The lower is the same. Only the upper is different. You won't benefit from a 65mm on the 86 heads. They do not flow past 4500-5000 rpm anyway. Just get/keep the 87 TB and upper intake and take it for what its worth....

i'm not sure how to check, but when i got the car they said it had head gaskets changed and they put e7 heads on it.

how do i find out?
