Thread: 2.3L VE Motors Build For Cheap With Mazworx Headgasket

And a properly setup individual l throttle body setup is a budget?I learn something new everyday!

The day I see an ITB setup cheaper than a custom intake manifold give me a call.

Sometime we need to thing before we type.

It gets done all the time on diyefi forums. You can hack up a bike throttle body setup and mate it to stock runners for less than $300.

you really think its that easy on a SR20 equiped car. I guess you are ready to go standalone to.

this 'budget' thread is funny as hell

Can the GTIR SR20DET intake manifold which is itbs work on the SR20DE and SR20VE?

You would have to if you were going to do a DIY itb setup.


43mm insider diameter on the R1 ITBs.

4*((43/2*pi)^2) = 18 248.9 mm^2

N1 throttle body at 70mm (IIRC)

((70 / 2) * pi)^2 = 12 090.3 mm^2


The cross section of the total throttle body area is 50.1% larger and it has a straight path to follow.

How is that not an effective, cost minded budget intake setup?

How much is your ITB setup vs a $800 ported N1 set up?

keep in mind you will have to add in the cost of your standalone and injectors and i am not familiar with how you expect to bolt these itbs onto your head.

You are also going to have to spend more time dyno tuning for idle on itb's than ported n1 and calum ecu. So let's say 4hrs at $100/hr.

because you then have to go to a MAP sensor based stand alone (which is expensive enough in its own right) with a new tune and fiddling for ages trying to get a nice idle and cold start etc. So by the time you pay for all that your 'budget' has just gone out the window. A modified standard intake would be the budget solution. Something along the lines of what corey did or the O2 manifold with longer runners. It would be a cheaper solution in the long run.

ITBs will not make more HP than a properly made intake manifold and TB setup.

They dont do so on boost and they dont do so NA.
