currently have a 195whp motor, thinking about installing itbs as a finishing touch to try and achieve a FAT powerband

yes, i looked around, and everything seems to be outdated.

im looking for dyno graphs of a stock head port, and stock 1.8L block itr with itbs. thanks in advance.

 

in for some info!! i asked the same question in the all motor section and got it locked

 

In for this as well. I plan on doing the same, but slightly build the bottom-end...
There's this thread, but the set-ups vary"
ITB's Post

 

I'm dynoing my car next week, basically stock bottom end with full valve train and itbs... i'll post the graph on this tread first...

 

Nice...can't to see it!

 

I remember you....

What happened to your 220whp stock block ITR motor?

195whp is about right for a stock block ITR....

 

the finest of castings will still require a port match no matter how good. you'll also need the requisite engine management and tuning to take advantage of them.

then you'll find that a ported head would better compliment the itb's. and on top of that, better cams (and the valvetrain to go with it) will enable you to get into the powerband sooner and widen it.

it's a slippery slope.....

An accurate dyno?

 

I bet it was still done on a dynojet

 

 

Sounds like a cool project, nice man

 

dyno was jeff evans dynapack

 

Let's get this going graphs up!

 

I had A-Sports ITB's on my stock internal B18C5 with Rage Tri-Y Headers, Apex B-Pipe and Spoon Sports Street Muffler tuned with Apexi Power FC by Church Automotive. I ended up with 194hp / 146tq to the wheels. Hope this info helps.

 

that's impressive.
those numbers are a tad high...IMO

 

I definately enjoyed the tq but missed the top end...I think the A-Sports would of ran better in the higher RPM's with some bigger cams...Just felt like it was starving for more air flow

 

Were you running stock ITR valvetrain?
What cams would you of considered?

 

Yes all stock internals...I dunno maybe some Skunk2 Pro2's

 

hummm....
You would need to significantly increase compression for that. Prob. bore the 1.8L

 

I agree...I woulda prolly gone with some OS pistons too

 

"There is no replacement for displacement"

230whp NA here... 2L ftw.

 

Specs?
Graph??

 

Basic budget build up..

84.5mm x 89mm
84.5mm Cast pistons (Spark Racing or RS)
B16 Self ported head w/ quality valve job
ITR manifold
BC springs/ret
68mm TB
Hytech knock off
Blox B's

Lightly tuned on Crome... didn't touch the cam gears.
