Here is the setup I'm currently running.
Standard bore LsVtec with P73-A00 pistons, Z10 girdle, ARP rod bolts
Stock B16 head with JDM ITR 4-1.
I'm looking at getting a ITR manifold, CTR cams, Hondata and Cam Gears.
Then I'm trying decide how I should proceede accordinly. I have a few options, I can pull the bottom end apart again and replace the pistons with CTR OB pistons to bump the compression (10.8:1 to 12.0:1), or I could send a B16 head to get ported and polished, or I could possibly trade a B16 head plus some cash to my buddy for a Type R head.
Basically what I plan to do is bump the compression either way, and do head work or use the type r head. Obviously it'd be easier with a properlly ported head vs the type r head, but it will be much cheaper to go with the type r head. Do you think 200 whp will be possible with the stock ITR head?

 

yes 200 whp is more than possible with stock ITR head. THis head flows beautifully for naturally aspirated motors. with 12 to 1, an ITR head, and your CTR cams your probably looking at more of a 185-195 whp (that is with hondata and an above average tuner. But that same compresion and ITR head with JUN 3's, Toda b's or C's, or SKunk Stage 2's you could see 205whp-215whp depending on supporting mods like of course header and exhaust, injector size, and skill of tuner.

 

I was really hoping to do it with stock cams as I have seen it done, and it would significantly cheaper than upgrading the cams and valve train. A good port job will be about the same price as cams and valve train, so which would be the better investment?

 

I also have the oportunity to pick up 290 cc prelude injectors for a decent price...
I will be running the stock PR3 at first at least for a month or two untill I feel comfortable enough to get a Hondata. Do you think I'd have a problem with detonation if I used the bigger injectors (I'll be using 92 octane for the most part, but I can get 94) I'm just concerned it'll run too lean with the stock b16 settings, then if I change the injectors too rich.

 

Possible, but not likely.

spoken like a true genius.


waddup voodoo!?!?!

 

Possible on the stock ITR head, but not likely?
What about if I get the head done?
and the extra compression, is that necessary?

You know me, just talking **** in GD&D

 

I think you may be struggling to do it with CTR cams. People may have done it but that doesn't mean anyone can (no offence)

 

dang...
well I'll give it a shot, I'm sure I'll make decent power. Does anyone have experience tuning cam gears they'd care to share?

 

save your money and dont buy camgears, then buy bigger cams.....

 

the thing about buying bigger cams that is a bit of an annoyance is the fact that you have to upgrade the valve train, adn the cams themselves are expensive. Plus when I use all these components I know they are designed to work together, but if I change the cams, I'd have to change all the components to make them work.

 

You should be able to hit 200 with a done up head and CTR cams. I made a little over 200whp with a stock ITR block, DPR ported head, and ITR cams.
Good Luck on your build.

man love that attitude! 200 is probably possible, but you have to get all the stuff you said you would have done! get the highest compression you can out of what you got and make it flow very well! you go t nice stuff so you should get 200 but liek I love to say TUNE THE S*** OUT OF IT! good luck and keep us posted on your build.

 

heh, thanks guys. I really have no clue what I'm in for because I've never tuned anything before, heh. Is there any really experienced tuners in the Twin Cities, MN area. I'd probably be better off driving down there, since there isn't much experience in Winnipeg. What about injectors? I'll be running the stock PR3 ecu for a cupple months but I'm thinking about getting a set of 290 cc prelude injectors, how will the LsVtec run with a PR3 ecu and 290cc injectors?

 

About as much chance of me makeing 200 whp(wind horsepower) with a fart.

Not what you wanted to hear? Well go dyno it and prove me wrong.

muaaahhhahahahahahhahahahaah..
WHP=Wind HorsePower

 

what would make it so hard that everyone is saying so. it seems as though many people are doing it?

 

200 whp is not just some easy thing that every joe schmo knows how to do, especially when your not using big compression and big cams, it takes tunning and using the right stuff.....but with a good head, good header (dtr) and some good tunning it can be done

im a newbie in here man...

 

an easy way to bump compression a little...switch to a gs-r head..then modify that..

 

12:1 isn't high enough? I'll only be running 91 octane on a regular basis and I wont have the huge cams to bleed it off either.

 

i would go with the ctr pistons, and the itr head, good luck buddy

 

its not the fact that 12:1 isnt high enough, that should be more then plenty, its the fact that you dont want to build the all around motor and you are going to rely on the compression to make the power for you.....i have 11:1 compression on my motor and with cams, good header (dtr) and some port work i could be over 200 whp, because that is more of a complete build on a motor.... you need to have a over all good working motor and not put so much stress on one thing..
