purchasing a set of itb's as soon as i can figure out wich one i should go with.....

toda itb's or twm are my 2 options but my question is what would be better to get and why 50mm or 52mm itb's? need some advice thanks

 

what's your setup?

 

98 spec jdm itr motor...... i got the jun 3 cams, springs, retainers, skunk2 cam gears, p&P head, ericks racing ecu but i just got apexi vafc 2 installed...... so iam picking up a set of itb's but just want to kno whats better for the set up 50mm or 52mm itbs? and what about the short or long stack does that play a roll?

 

ok, what's your intended use for the car?

 

the use for the car is track racing not drag!!

 

Ok I'd go with the 50 mm long horned ITB's. The reasoning is that you are still running a small displacement motor at 1.8L vs 2-2.5L (range) etc. The longer horns will help torque, especially in the midrange through top end which is ideal for track use. Id' go with the shorter horns if it was for drag use and go with the larger TB's if I had a larger displacement motor.

I've seen a set of Toda ITB's used on a bone stock B16A2 with only a little mild porting and the torque and HP numbers blew my cars dyno numbers out of the water by a long shot. He was even using a stock P30 ecu too! He dynoed his car (91 CRX) right before mine and only did 3 pulls. His numbers were 162.6 hp and 117.0 lbs of torque. I had them tune my Hondata which made 154.6hp and 106.7 TQ (see mods in my sig). Made me take a serious look at those ITB's !

 

alright thanks for the input man appreciate it
