Hello HT! This is my first post so i'll try and do my best not to make a complete moron out of myself and I apologize to everyone in advance if I'm posting this in the wrong section.

My 2000 GSR is burning oil and needs new piston rings. I figure since the engine will have to be opened up a good amount, why not rebuild it a bit? Im thinking about going with:

USDM itr pistons
new rings (obviously)
oem 3-layer headgasket
stainless steel valves
dual valve springs
titainium retainers
ARP studs

I want to stick with the stock cams since the car is my DD. Ive played around with the zealautowerks calc and it say that all stock b18c1 internals with p73-A0 pistons will get my CR to 11.04:1

My questions are will I have any clearance issues with the parts im considering? Also, what should I go with for tuning purposes?

 

it should be around 10.8, i doubt it'll get to 11.+

 

The ITR runs 11:1 and it has the B16 head casting, which has a larger volume than the GSR head. If anything he'll run like 11.2:1 or so.

Regarding the Ti retainers, read my signature. Not the FS part, though it wouldn't hurt, haha. I am considering selling my RS Machines 82mm ITR pistons....

 

My gsr build is pretty much identical. i used o.s. usdm itr's, supertech valves/springs/aluminum retainers, endyn head, s2 intake mani and jdm itr cams. runs pretty good no issues though it could use a tune. but it passed bar inspection and cali dyno smog test. gl with build!!

 

JDM ITR runs 11.1-3 USDM ITR (10.6-8)

gsr head has quenched combustion chambers causing an increase in compression so how would a b16 head which is not quenched yield a higher comp? it wouldnt, the jdm itr pistons have a much higher dome causing more compression. jdm itr pistons in a stock gsr would yield 11.59.1 based on the zeal calculator. i dont know what calculator is more accurate because the cspeed racing calculator has different numbers for the same mods. i think the zeal calculates too high and cspeed is accurate i dunno.

 

awesome! thank you (and everyone else who replied) for the encouraging and informative advice. i just wanted to make sure when i rebuild it, it'll be done right the first time around. also might have run across a mighty valuable find. a neighbor used to have an ek coupe with an ls/vtec swap, that he ended up parting out, and still has the jdm itr cams for sale. might sell em to me for cheap

 

so would Blox Ti retainers be good to use? if not just tell me what you would recommend. im open to anything i just figured Ti was indestructable haha.

 

I prefer OEM retainers for a daily driver, specially if you won't go larger than OEM ITR cams.
TI retainers provide additional retainer to valve guide clearance which is needed for higher lift cams, but not required for ITR cams. Also, there is much debate whether or not TI retainers last as long as OEM retainers.
Also, I highly recommend Supertech valvesprings and retainers over Blox valvetrain. And if you do deside to go with new valves, I would look into "SI Valves" that's the name of company from southern California, not referring to Civic SI valves. I usually get a full set of brand new valves for around $150

 

Sounds good to me. So ITR cams, SI valves, Supertech valve springs, with OEM retainers? Sounds good

Does "SI valves" have a website? I live in VA so just dropping by there is out of the question hah. I appreciate the words of wisdom man.

if i were you, i would stick with OEM retainers and dual valve springs from a ctr or itr. Use OEM as much as you can.

In regards, to the compression, OP is using usdm ITR pistons, hows he going to get 11.2 or so ????

anyway, supertech stuff is good too but OEM ITR FTW!

 

ya im going with the USDM pistons vs. the JDM pistons because the dome on the JDM pistons is very high and i dont want any sort of issues whatsoever since the car is my daily.

i just figured why only get new piston rings when i could baby the motor around for a bit while and get all the parts i need to have a rebuilt head and better pistons to raise the CR just enough to make it fun

 

Also a question that has yet to be answered is what should i use to tune it? Crome, Hondata, Uberdata, Flashpro? or should i swap ecu's?

very confusing topic for me since ive been around hondas for years and years but this integra is my first so i havnt had the "pleasure" of modding/tuning one yet lol.

 

I had a very similar set-up for a while.
GSR with USDM ITR Pistons. Definitely get it tuned. I got O2 sensor cels in the winter time on the stock ECU. I'm running an Hondata S300.
You should also change your spark plugs. Use OEM also, ITR plugs work just fine.
