64mm Throttle Body

does the WR intake manifold have a largerer inlet diameter?

I don't think it does, but I will have an opportunity to verify that this weekend.


I was thinking even with the reducer you are going to experence a big increase in throttle responce as the computer will be letting in more air than it expects. 35% open on a 64mm opening is a lot more air than 35% open on your stock TB.

Can somebody verify this will work on a USDM Fit

[Tofuman]

if this works... someone should produce a quality reducer. it might make the intake piping a tighter fit against the battery though.

You bring up some good points. Since our cars have no air flow meter, the computer won't know about the extra airflow. There is a very good chance of running lean. This might make the car feel crisp and might yield better gas mileage, but could damage the motor.

Except near WOT because of the restriction going into the manifold would keep the flow the same as stock.

Probably the Blitz throttle controller is a better choice then unless you modify the manifold... now if that was only 75$ like the junked BMW TB

if someone can give me the year and which bmws it comes off (not sure if someone did) then ill look into this

- This TB is perfect for stock intake manifold
- WR intake manifold can't have a larger inlet diameter!
- Intake piping doesn't hit battery even with 2cm TB spacer (I tryed)
- Air flow meter??!!! Jazz/Fit has a map or tmap sensor! The car anyway doesn't run lean with this TB
- Blitz throttle controller is a game of 300$ and WR intake manifold for 500$ isn't worth, in my opinion..

To be precise this TB is only 0.90mm/1 cm larger than intake manifold inlet diameter (I'm referring to interior side of TB, not 64mm exterior). I built this "reducer" to avoid air hit this cm!!!

[Sugarphreak]

I am pretty sure the Fit uses a combination of the MAF and the 02 to do fuel adjustments. I have a feeling you would end up running way too lean, for the same reason I was running lean when I installed my intake manifold. you should run a check on your AF to see what it turns up.

BTW I can assure you the WR intake manifold is worth it I recently out-pulled an RSX with no problem with an extra 200lbs of gear on the back of the car (in a safe controlled environment in case anybody... especially mods were wondering)

I will measure the inlet diameter of the WR intake this weekend, also have an opportunity to measure the stock manifold tonight to verify the claim it is a 54mm opening.

the base model RSX, right? from a roll?

the 64mm TB has nipples for coolant.

I looked this up and for 2002 the 2.5i has a different ending number 444 instead of 445.

This was not confirmed. That was my guess.

Pretty sure it was a base, but was from a dead start and no RPM launch. I stayed ahead of him easily even with a shift. Those things must have outrageous RPM redlines because I was halfway through second before he shifted

Was just an interesting thing that happened, probably an novice driver or something.

The Type-S redlines at like 7800-8200rpms
Not sure what the base does. 6800rpms?

[jits14]

They are geared largein the 5spd, but they get through the gears almost as quick as a fit. He might not have been giving it wot.

[Raaaaaaaaaay.]

Im sure he was. Bases are slow. :-/

[JamesBizzle]

wow... tagged for interest.

[Injundon]

if the plenum is ultimately 47mm all you will get is slightly quicker response and you'll have to use less pedal input for for the same airflow.

Based on some research on ebaymotors, it isn't this part model and corresponding bmw fitments. If you notice, the front looks a little different and the plug is different.

the ebay picture could be wrong though...

It seems like its only the 2.5l one if someone can find a picture of it, but it might be a european version. I searched the bosch number the OP posted and it pulls up all european models like the alfa 156 and some audi models but its all in foreign languages.
