Hi,

I'm looking to push power utpo 200bhp whilst keeping my JDM SiR Sol completely NA (stock 168bhp) and i've made a few purchases to achieve this. I've bought the Hondata S100 ecu, CTR cams, DC 4-2-1 header and denso iridiums (all yet to be fitted) - my current setup at the moment is a straight-through exhaust w/decat, CAI, magnecor leads and fuelcat (this ups fuel octane rating to the JDM standard 100RON). I'm trying to keep all my costs down to an absolute minimum - I want to keep it completely as a street car (no track), with normal idle and as OEM Honda as possible, whilst keeping (and dramatically improving) my bottom end and increasing top end. 200bhp would make me but 200whp would make me !!

1) I'm looking to have the engine head skimmed, ported and polished - should I go for the OEM Honda gasket kit or for an uprated head gasket set? Also, will an OEM timing belt do aswell?

2) I've been told that at the very minimum i should upgrade the valve springs for ITR ones to avoid the possibility of valve float when installing the cam. Can i get away with the existing stock springs and retainers without replacing them or is it wise at the very least to change the valve springs?

3) Is it worth extrude hone porting my exisiting intake manifold and boring the TB? Whats a good size bore for all the mods i've listed? 68mm?

4) I'm also considering purchasing some ITR con-rods and pistons - this will increase compression but is it worth since i'll only be running the CTR cam? Will i gain significant power throughout the power band, top end or none since i have a mildish cam? If i do install rods/pistons, will i have to replace the clutch/trans or can i get away with it?? What other expense is invloved?

5) Fitting a lightened flywheel - will this disrupt idle?? i've heard it can be a pain in the a$$ to drive in traffic.. is this true? is it worth it?

I've viewed Omniman's 200whp project on the B16.

thanks.

 

Im trying to build my JDM B16A to 200 whp too. Do you have the whole Omniman 200 whp B16 project or did you just see the trailer that is like 45 mins. long???

To answer your questions:
1) I would go ahead and upgrade the timing belt to a Toda or other stronger unit, since everything is going to be apart....give you a little better peace of mind.
2) You may as well go ahead and upgrade the valve springs and retainers while everything is apart so you can go ahead and rev it higher without worrying about stuff breaking.
5) I'm running an Exedy Single Plate Organic Clutch and Exedy Lightweight Flywheel (around 9 pounds I believe) and I don't have any idle problems and it's not that bad to drive it in traffic.....it makes the motor rev a little faster I have noticed.

Hopefully I have answered a few of your questions

 

cheers. actually i viewed the trailer that was 45 mins long - is there more info on it? can you post up some links? thanks again.

 

getting the OEM Honda Gasket set is ok, but I would suggest this. Get the set except for the intake manifold gasket and buy a Hondata or NEXTGEAR intake manifold gasket.
These gaskets are designed to reduce heatsoak on the intake manifold which re-heats the cold air coming into the engine therefore, reducing the effectiveness of a CAI.
I'll tell ya right now Hondata gaskets are known to melt, however NEXTGEAR makes intake mainfold gaskets for Honda, Toyotas, Nissans, etc. and they do not melt. if you want a peak there is a link to the NEXTGEAR website in my signature.

Check it out!

 

I only saw the trailer that was 45 mins. long, but I was under the assumption that they were going to put out a longer DVD or something like that....I was hoping somebody had a link or something to where I could watch the whole thing.
