Like the post says, I was wondering if it was possible to hit 240-250 whp outta of a B18C1? My motor is stock rite now cuz I havent put anything into yet. I starting to buy the parts I plan to use on my motor and was wondering if someone can tel me whether I'm using the correct parts or not.. so far this is what I have planned to buy:

-shot peened GSR rods
-either JDM ITR, CTR, or forged pistons ( i wanna run 12:1 c/r)
-ported + polished P72 head
-Buddy Club Spec III or Spec IV cams ( although my buddies tell me to run Skunk2 stg 2 cams
Buddy Club valve springs + retainers
-Blox intake manifold
-Spoon or Zero 1000 intake
-Tanabe Hyper Medallion exhaust that I'm getting off my buddy's ITR
-Rc engineering 330 cc injectors
-BDL fuel rail

As far as a header goes, I'm still unsure as what to get. I was considering using my buddy's JDM ITR header because he just bought the Hytech header for his ITR and he has no use for his old header, but I'm not sure if this will be enough to hit my hp goals.

Tuning will be done by Matt. He' s a whiz using CROME and thats the only guy I wnat touching my car when it comes to tuning. HIs work speaks for itself.

The c/r I wanna run might be too high I think, considering I wanna make sure the car stays reliable because it is my daily driver. The engine will stay in my 97 DC2.

So, what do you guys think? Am I dreaming too much or is 250 whp possible? What header should I use? Is the c/r I wanna run too high for a street car? what about the valvetrain I want, is it good?

Any help would be greatly appreciated before I go spend money on parts.

Thanx.

 

To hit 250 you will need more displacement than 81mm or even 82mm will get you. The JDM ITR header will also be too much of a restriction to reach that power level. You should not even be considering BC3 cams-Pro2's or 3's would be more appropriate. You will need bigger injectors than 330's as well. Hitting 200 is not terribly difficult, but after 230, it gets much tougher to get more.

so u suggest lowering my hp goal? what header and cams should I run then? what injectors should I run? I would actually be pretty happy with 230 whp.

 

Definitley lower your goal, pulling 250whp from an NA GSR daily driver is impossible. Daily driver = passing inspection/emmissions. 230whp is still asking too much also.
Come up with a more realistic goal, and we all can much more accuratley help you.

 

We're running a GSR motor in our car and it makes 215 hp. Were running some CTR pistons with stock rods and crank. Our head is ported and polished, resurfaced with Supertech valve springs and retainers and some GSR reground Cams.The Intake manifold and T Body are Type R and also ported. It's been fun playing with this motor. We recently changed our header from the Type R style to the Rage Tri Y header.Hopefully we picked up a few more. But reaching 250 is probably impossible without a bigger bore motor and mad compression. We'll see.

getting a stroker kit of 95mm with 12-13cr and sleeeve the block to 86mm will get you there

 

Vteckidd's old set up was sick, and he didnt even reach 250 whp. His was a 84+ bore, pro2's, but stock stroke i think. In the end he ended up with 237 i think. So 250whp on a stock bore would be damn near impossible i believe. To stay daily drivable you would have to maintain a 12.0-12.5:1 ratio i believe. So unless u wanna stroke it out, i think lowering your HP goals is ideal. Header wise... following your friends example would probably be best. That or some Rage/Whitfields Tri-Y

 

trackspeed has a stock ITR block project right now with more than
230 at the wheels. you should hit them up

 

Is that block gonna be in a DD? I figured it could be possible, but as a daily driver?

 

stroker kit, CTR pistons, PnP head, and skunk2 proseries will help u get there

 

Typically, a "Stroker Kit" Will include pistons with your choice of compression......

 

Well, considering everyoen is telling me to lower my hp goals...what could be achieveable? Would 210-220 hp be possible?

I don't wanna stroke it right now and boring is definitely not in the books right now....at least I would liek to break the 200whp mark.

What do yall think?

With the right parts and good tuning, without a doubt.

 

I was on Inlinefour.com and saw the JDM ITR pistons. are those better to use than USDM ITR pistons? I ask because I heard that if I run the CTR pistons as is in my motor, the piston could come in contact with the valve. If that's the case, I'd rather run ITR pistons...so what would be better and which one would yeild the best compression out of the USDM or ITR pistons?

i don't think he's trying to get this motor to pass smog if he's building this type of motor. 230 whp is not that hard i don't think...it's just quite a bit of head work as well as bottom end work. realistically, try to shoot for 220-230whp on pump gas...that's pretty good for a daily driver imo.

also, use a bigger manifold and throttle body if you plan on doing over 200 whp

a stroker kit will get you to your whp goal but reliability will degrade on that motor...just a thought.

 

Well that's the catch with what he's asking, acydphryck. He said it's a daily driver, which means he needs to pass smog and it has to be reliable.

230whp is a chore to achieve, you gotta have a big chunk of dough and know what your doing. I'm not saying it impossible, it's difficult and expensive. When you get into that level of power from a B18C1 NA, streetability is gonna take a hit no doubt. You need to really open up the engine at both ends, so it'll be pretty loud, and good luck with passing emmissions, you'll need it.

In a GSR block with a GSR head, oem headgasket:
-JDM ITR pistons = 11.3:1
-US ITR = 10.8:1

Which is "better"?, whichever one gives you the proper compression required for the camshafts you choose to perform at their maximum potential. An engine with cams that lack the compression they require = an overcammed engine. An engine with too high compression for they cams the have = an undercammed engine.

CTR's aern't gonna hit the valves unless you screw up the install royally. Wherever you heard that properly installed CTR pistons will hit the valves in a GSR motor, you should stop getting information from that person/forum. But then again, you probably heard it on this site.

 

just get some pr3 or p30's......im runing pr3 and loving it

Well, the valvetrain I plan to run is gonna be either Skunk2 stg. cams or Buddy Club Spec IV. Would the c/r yeilded by the JDM ITR pistons be good for those cams? I 've also decided to use either the SMSP header or the RAGE/Whitfield header. And yes, you are right, the car has to remain streetable because it is my daily driver so it has pass emissions and it has to be reliable. So would you say that a range between 205-220 WHP be attainable with the parts i wanna use and good tuning?

Yes, that goal sounds alot better. That should well attainable with your future set-up. Proper tuning will help alot too.

 

i have a gsr fully built.i just got it back and i dont know where to go and get it tuned.it is a b18c1 block.1.8 liters,stock gsr crank,eagle h beam rods,je 11.5.1 forged pistons,ported and polished head,black knight 1mm sized over valves,radius cut on the valve seats,radius valve job,comp cams dual valve springs,titaniun retainers,comp cams camshafts,in.290,ex.296,440 injectors,v2 cold air,aem fuel rail,255 fuel pump,golden eagle block gaurd,golden eagle cam gears,jdm itr 4to1 header,type r oil pump,balanced and blueprinted bottem end,other mods but tired of writing.what can i expect for this motor to pull on the dyno?

Thread hi-jacker! Start a new thread or use the search button...try searching "Bench racing"

 

I think he's doubling as a thread hijacker and bullshitter. How could an engine with that many mods even run without being tuned? And his eventual question belongs in a local forum anyway.

 

Yea, im gonna have to agree with you. I think its time for him to read my sig.

oh it would probably run....like ****

 

hey ******** its not in the car yet.i work at gilmore automotive and everything is on the stand.dont know who to get to tune it.so if yall wanna be more friendly and ask questions before making assumptions that would b great.thanx alot fockers
