Type2-L · 09-19-05, 12:52 PM

Larger bore.

I thought they were the same. could be wrong.

Is KMS throttle body a "good buy" Christian? (Dv8)

JTJohnny1020 · 09-19-05, 06:32 PM

if im not mistaken on this, i think what happens with the kms is u lose hp but gain in tq. I THINK...

I have had my JDM type 2 TB and my old Type 1 TB side by side and I could see no visual difference in TB diameter, in fact I used the Type 1 TB when I did my JDM Type 2 swap, you almost have too cuz the throttle reel is larger on the Type 2 then it is the Type 1, causes idle issues as me and Type 2-L have found out

A bigger throttle body typically gains horsepower and loses torque.

The KMS is out of production--yes?
Its pricetag was steep.

Exactly

The TYPE 2 is bigger by 2mm or so, the KMS is 3-5mm bigger with a bigger butterfly. I am very glad i got it a while back. its the perfect complement for my additional displacment. Call KMS im sure they can make one up from your core.

no wonder I didn't notice a visual difference, doubt anyone could tell 2mm difference with the naked eye. Are the throttle plates the same size on the type 1 and type 2 TB? also, this might be a shot in the dark, but if the KMS cant be made anymore, wouldn't it be easier and cheaper to overbore the stock TB and have a larger throttle plate made? or are there also other differences in the KMS TB?

I kept the Type 2 tb, I just swapped out the reels.

yeah I remember that whole discussion we had a few months ago, good pointer by the way, the idle issue would have really threw me off, that was an awesome heads up btw. I dunno if the 2mm difference in TB size would even be drastic enough for me to swap the Type 2 TB back on, besides the spare parts from both motors are slowly finding their way into my new project. Right now my $ is tied up in getting all my body work done and getting my suspension and braking system to a point where I can be happy with it. after that I'll worry about making more power and doing a build up with my spare block. and with gas prices where they are now my bike has been getting alot more use than my Legend.

FYI i took a Caliper measurment to the KMS TB and its 64mm.

follow up, i found an old TB i think its from my type two and its 59.7mm. so a little over 4mm difference in size straight through with the KMS.

We stripped out a Type 2 today the throttle plate bore is the same diameter as a Type 1 62mm. Has same code number stamped on throttle plate, 1CJ. Will measure the cams and compare to Type 1.
