Right I'll be building my engine back up quite soon and I either need to buy a new larger throttle body intake and new inclosed filter and some new injector's which wont be a cheap :(

Now do I just bite the bullet and go all out and buy ITB's?? or do I just get the necessaries for my inlet??

What are the pro's an cons of ITB's V Inlet TB and good filter??

anyone had any experience with ITB's? As I'm a complete noob with the stuff lol

Also the spec of the engine is:
B18c4 block
ITR pistons
Weisco 12:5:1 pistons
B16a2 head with good head work
SK2 tuner 2 cams
SK2 valve train
10 thou off the head

Help please :D

Doubt bigger injectors will be needed much. Maybe a set of prelude 290cc's at most. Would think the std 240cc's will be up to the task though.

As for the TB I would keep it simple and stick with a 62mm ITR one maybe get it taper ported out like the spoon ones. Big 70mm TB's arn't really needed until your into the full race cam stage or going boost.

ITB's are quite a big (expensive) jump. Wouldn't say they were that needed. Would see much bigger gains but would take a good amount of more time to tune and cost alot to fit.

There are plenty of gains to be had from ITB's but would say they were that much worth the money and hastle. As B series to prity well with Intake mani setup anyways.

Well i havent got the following parts you see:

Inlet mani
TB
Decent filter
Bigger injectors
all nec pipe work etc

so this is the predicimaent i have you see
 
Just get yourself a Type R manifold, B18C 62mm TB, stock intake pipe and a carbon airbox. Tegiwa rep or ice box.

Dont worrie about bigger injectors. with Tuner 2's I doubt they will be needed at all.

ITB would be prity cool and deffinately see gains but the choice is if they are worth all the extra cash and effort.

imo b series no, k series yes. simply due to the positioning of them and the fact that they are tricky to tune on a b series.
 
yes epic extra jdm points on the conversion front, will be really different then
