ok. i have a ls vtec crx specs are:
stock jdm b16 head
b18a bottom end with jdm b16 pistons(12.18 c/r)
arp rod bolts and head studs..all stock other then that..
s1 tranny..with lightend flywheel act clutch and heavy duty PP
and of course intake header and straight 2.25in exhaust.
the fuel is stock the car is untuned and basically thats it..i just kinda lookin for the best hp gains..i was tryin to pick up some itr valvetrain and then get a tune..hopin to gain atleast another 20hp or better..since i think im runnin really rich..but opinions are always very helpful..i do plan to keep obd0 and have it tuned on zdyne..and i want to keep it all motor..so any helpful advice as to the next step...its not feelin so fast anymore..hehe

 

Zdyne is a killer waste of money for a obd0 ecu tuning solution.
Look into turbo edit or bre.

Why do you think your running really rich ?
Have you ever put a wideband oxygen sensor on the car to monitor true air/fuel values ?

 

no...i do have narrowband..which i know sucks ass..but the muffler end is super black..and even though its a narrowband..the a/f gauge is stuck on the last green bar all the time..also..where are u located..im really thinkin the best thing for horsepower for me..is cams springs retainers and a good tune..

 

pr3 pistons in an ls block with a b16 head are 11.3:1
p30 pistons in an ls block with a b16 head are 11.5:1

Itr cams/valvesprings/retainers 2.5 inch collector exhaust manifold & exhaust system would open the motor up, along with a good tune.

 

also i could be wrong on the c/r...i have jdm b16 pistons..with the block bored to whatever honda sells the pistons at? i heard u have to bore just a tad bit..and as far as the c/r ..ive heard with the pistons i have...i was told by one that it was 11.54..and another it was 12.18 or 19?

 

the exhaust i got..i got a hp racing header and straight 2.25in exhaust..no cat..and pretty much a straight through muffler..nasty loud..but o well..i tried to get the cams springs retainers today..went to orlando and the guy hasnt even taken them out of car..although he never wrote me back anyways..so i went out there for anything..how much u charge to dyno tune..and about how long do u think itd take..cuz im sure its hourly..and i would like to get a numbered result..thanks a lot..

 

Get the car together then consult some one in the tuner directory for tuning.
If you are interested in having me tune the car, simply check my signature or pm me.

also after the cams etc..a port n polish very good? for head tb and im all port matched..and should i get tune after that..if i can afford it all..might be overloadin myself..i need to find out some prices..
