ITRCA

I have been posting here for a while and I want to continue to build my ITR, but I am looking for some guidance on where to pick it up? Right now I am at 194hp and I want to get to about 215hp while keeping the car reliable.

Current Modifications:
-JDM B18C*R engine
-Hytech big tube header
-Hytech twin-loop exhaust
-Mugen Intake
-Spoon Cam Gears
-RC 310cc Injectors
-Hondata IM Gasket
-Hondata S300 with a 14.9AFR tune (which I think can be improved)

Here is my dyno chart:


The Quirks:
She throws fuel at crossover like I have never seen even with the 240cc stock injectors. I think my tune may be too rich and/or I may have some excessive blow-by.


You guys have helped me get this far and I want to push heR a little more. I would like to thank you in advance for your comments and help.

194 by most standards is a very good number, working for this ultimate goal of power will start chipping away at your reliability requirement.

boost got me there

but seriously.... it did.


isnt 14.9 afr kinda lean???? my car will missfire at idle with an afr like that.

i would suggest cams. but forsure reliablity goes down....

BTW... looks like that says SF on that dyno? several people i know think thats not 194whp....

was gonna suggest that as a mod to get your 215 also, but you moved away?

I don't know what to say to that??? I put down 192.4 at Axiom a couple weeks before that and 192.7 on
one of my first pulls in the video, so I think my numbers are right after moving to colder plugs. A lot of shops in Washington have questionable work practices, but Kyle(Axiom) has always sold me legit stuff and Matt (SpeedFactory) has never done anything in my mind to me or my friends to make us think otherwise of him or his company. Matt and his associates have always taken care of me even though they think N/A cars are boring.

just saying that several people i know have had cars run back to back from SF dyno to other dynos and have had different numbers. but also they have had higher hp turbo cars, not NA.

not saying bad about there people or company. i hear nothing but good on both. just that the dyno reads a little high...

I think my numbers are consistent with my setup and others.

Since nobody has answered... I'll start

Go with a bigger IM, like an Edlebrock Performer X and larger TB.

I have both FS, if your intersted. Made a lot of difference on my setup honestly.

I will see if I can put some funds together for those parts....

Only other things I would "think" about would be cams and pistons.

Raise the CR, and compliment with a nice set of cams.

or... go all out and bore or stroke or both...

That was going to be my next step should I have kept going on.

but I am looking for some guidance on where to pick it up?

In this order:

Injectors: 440's
Pistons: don't care about brand, must have big domes
Cams: don't care about brand, must have big lobes

wash, rinse and repeat
