sounds good i'm thinking....

So, previously, i dynoed my B18C1 (OBD1) at 154whp.
it had:
- Skunk2 Intake Manifold
- B&M FPR
- AEM Cam Gears
- DC 4-2-1 Header
- cheap intake tube
- Chipped ECU

I have on order:
- Supertech valves (flat bottoms)
- Supertech retainers
- Supertech valve springs
- Portflow valve guides

Next, I'm deciding on the pistons I should use. It's between the p30s or ITR pistons. The p30s have the lightness (revability) but the ITR's have the higher compression... Any recommendations?

Finally... cams. I'm debating on whether I should get the CTR/ITR mix or get some aftermarket... like Skunk2 or crowlers...recommendations for these would be helpful too.

Then, I'm getting all new gaskets, water pump, oil pan (moroso road race one, oh yeah!), ARP head bolts and other associated hardware, and bearings.

basically rebuilding the whole engine with some aftermarket junk in hopes of achieving reliable and usable 200whp.

I should probably get hondata too, but that's further down the road. need to gather parts first.

So, any help is appreciated!

 

if your upgrading springs then you might as well get better cams too. put those springs to use.

 

well, what do i know?
but here goes:
* ITR or CTR pistons, unless you coat the p30 skirts
* aftermarket cams

 

go p30 pistons, the coating is not necessary. since you are getting the flat valves your compression will be pretty high with p73-00.

jun3 cams or buddy club.

 

the difference in compresion is neglegable, its like a .06 differece. go with the p30's IMO

 

i dont think that'll hit 200 at the wheels. probably 175-180ish... but it'll still be pretty damn fast.

go with OEM pistons (the ITR ones would be great, CTR would be nice too - as they are slightly hight CR i believe)
aftermarket cams -- get some used TODA cams (the B's) ... just keep your eyes peeled in the classifieds in here. remember, cams work the same new or used. get them used!!

 

in a gsr engine you are looking at like 13+ compression with ctr pistons. i dont think you wanna go that route unless you want to do some serious tuning

 

well he said 200 whp. i think the high CR would help. he could always get a thick head gasket to bring it down a tad...

 

How about Buddy Club 3's for your cams? They're supposed to have really good mid-range performance and I would think that would be ideal for Auto-X.

 

I would do big compression, and big cams man. I LOVED my skunk IM, and programed p28 however, I believe that made all the difference on my (crashed) cars buildup! 178whp. I think I could have easily made 10 to 20 more with tuning, and more compression/bigger cams.

Kam, why don't you speak to Robert "Rocket" Martin about this, he can give some very good advise. you might need to, as many said, increase CR to pretty high rates, and cam it, as well as do some headwork done.

Why is that? I see b18c5s dynoing at 190whp with just PCT pistons.

I'm thinking, I'm improving over the ITR valvetrain and getting pistons


I may get the head port/polished, but, i'm trying to keep costs under $1500 for the entire rebuild.

I appreciate the feedback so far.

I'm thinking the P30s seem like the best choice... i'll probably go the route of total seal rings (any objections?).

Cams, what choices? I'm looking for under $700 for both.

 

if you can use factory pistons, meaning 81's or overbore factory size. Use them.
total seal or any hardened rings arent very friendly.
there is nothing wrong with factory rings even if you were boosting they would be ok.

no, man, i agree with you. you're definitely going to need to do some compression uppage with pistons.
Total seal rings... i agree with the guy above. i havent had good experience with them. couldnt put my finger on how or why they went bad. always respected redline, but drove spirited. and now 25,000 miles down the road, im losing a quart of oil every 200 miles. (oh, this is on a D16A6 motor, btw ... not my B18C-R )

i guess in this situation, i would just say OEM OEM OEM. honda makes the best parts for hondas, so go with them.

and good luck with the build. i hope you hit 200
keep us all posted with your progress

 

yeah i never was succesful with the total seal stuff, it never totally sealed at all. lol

use the itr's, **** use the jdm itr's. the compression ratio is 11.3:1. their plenty light for an all-motor application.

get your hands on some 99-01 jdm itr's or ctr's, really doesnt matter cause they have the same ground specs. i run 00' jdm itrs and they are awesome.

i used all honda oem parts when replacing the old units. jdm itr rings, wrist pins, bearings, pumps (w/o) and im pretty sure a gsr hg. OEM ROCKS! i get awesome gas milege, awesome top end and great pedal response.

basically i have a b18c1 w/ jdm itr pistons, wrist pins, bearings, rings stuffed in the block and a 00' gsr valvetrain under the 00' jdm itr/ ctr pistons. i ran a skunk2 im and a jdm dc 4-1 hdr...i loved every minute this motor was in my 4dr teg! it dyno'd at a baseline run of 170whp, 120wtq @ 8200rpms. the high compression, cams and chipped p28 made all the difference to my motor than when it was stock....

....now its in my rex

i completely agree w/ droppedcrxsi, streetmodified and mostly everybody here on the issue that with neptune , an upgraded valvetrain and some headwork hitting 200hp @ the fw isnt too hard to do.


**** 170 sure does get you scootin pretty damn quick...let that be in a 2600lb car or a 2100lb one

So, no one recommends the Skunk2 S2's over the ITR/CTR cam combo? hmmm...

 

anyone run Supertech pistons?

 

I bought the CTR cams for cost effectiveness and reliablity over the SKUNK2 but if you have the scratch then go with JUN stage 3. I have heard they are OUTSTANDING! But have not ran them yet. CTR's are great everyone will tell you so. You can never go wrong with HONDA OEM. I have also heard great things about ROCKET cams, outstanding numbers with his products. Check him out he has great package prices...as long as you have not bought the SUPERTECH stuff yet! You could also look at FERREA valvetrain parts. Geoff @ FULL-RACE turned me onto them. GREAT PRODUCTS AS WELL. Anyway good luck with what ever you choose.

 

with all the info i have gathered s2s2's will be the perfect cam for itb's...with my itr's i make power all the way to 8500rpms. they seam like they will continue to build power with more rpms. another thing is that i built the motor with daily driving as a KEY factor..so lumpy cams werent an option to me.
