We put a new head and a new stock ported and polished intake on the hatch and retunned it this is what it made. It still has a stock throttle body and two and a half inch exaust with a resonator and muffler.We did have to go from stock injectors to 550 rc.

 

the bottm line is what we made last time.

 

Whats the total setup? H trans or H2B? And this was only the intake manifold? Over 25ft/lb gain at 5500rpm? Great with good gains throughout

 

i think the dyno reads high. what other mods? cams? etc. track times will back up the power.

 

I doubt Mainstream's dyno reads high. I got my 84.5mm b20vtec tuned/dynoed there and it made what I was expecting.


Plus, Vteckidd uses this same dyno to test all of his headers on.

 

wow pretty impressive. what are some other engine specs?

 

...we're all dying to know the specs of your motor Jones

 

well the dyno doesnt read high so dont start calling bull **** i got plenty of pictures , videos ,and witnesses if you want them . My dad has 40 hours in the head on this motor.

h23 crank
golden eagle block
cp pistons 88 milimeter
h23 crower rods
stock ported h22 intake
stock throttle body
skunk 2 stage 2 cams
ported and polished head by my dad
kidd racing header
rc 550 injectors
aem cam gears
cc the
motor its 12.3-1
m2b4 trany

 

oh, i remember reading about your dads EG build. he must have done a bitchin job on the head cuz its putting out some great numbers, especially with that stock throttle body. any plans to go with a larger TB?

 

sounds like 2.3 liter instead of 2.2(h22). when was the car dynoed when it made the old numbers ? tats some good power.

 

Your last dyno sheet was 231/171, wasn't it? How'd you gain 20whp and 10tq?

Regardless, impressive numbers, especially if the bottom end is still the same.

 

I agree the dyno isn't putting out high numbers. I had a similar setup...

 

what kind of flowbench did your dad do his work with?

 

Wow... awesome!!!

 

nice number for that set-up

 

He actualy just made the piece so we could use the guys flow bench on our head. At the time he did the head we did not have a flow bench availble so he didnt use one. Yes it is a 2.3 liter sorry and the bottom end is a little different by raising the compression from 11.87 to 12.3 and going to a 88 milimeter bore. We didnt want to change the bottom end but found out the hard way that type s pistons are not compatiable with steele sleeves they will not work. It doesnt realy hurt the sleeves just eats the pistons up. You can do this same build with a stock block and type s pistons with a little shaveing of the head get the same compression we just had a sleeved block laying around so we decided to use it.

 

he doesnt want to put a after market throttle body on it he like to pop the hood and it look stock which it does right now and he hates it being loud so no chance of bigger exuast it his daily driver we was not planning on making nothing like this power with it so we will just leave it alone . I just bought a cx hatch a good bit lighter than his si we are going to start on it now.

 

I only made three passes with the last setup running 12.7 @ 108 still spinnning bad and yes the track will tell the tell this car is a si and still has the spare tire in it no weight reduction but it should still hit low twelves .

 

what model SI is it? what weight?

 

Get an s2k tb. Looks plenty stock.

 

It is a 92 si wieght is 2500 with me in it i wiegh about 220. How big is a s2k throttle body realy interested thanks for the info.

 

Something like 65/66mm I believe.

 

jones, heres a pic of my Omni throttle body. it looks completely stock and is tapered from 68-70mm. its better than the s2000 TB. heres a link.... http://www.iapdirect.com/product.php...6&cat=0&page=1 they're $150 with free shipping. you cant go wrong with this deal

 

Wow thanks

 

Seems to be alot people asking about there stock h22 intakes which is what im running and making good power with and this is what i did to it and what it looks like. The top is stock just took the butter flies out and cut it like this.
