I'm in the process of a mild GSR build since one of my landings had cracked. Below are my build ideas, want to know if anyone has any estimates on power or recommendations.

Head:
Oem gsr valves with a three angle job and supertech dual springs and retainers.

Bottom end:
Stock b18c1 block with a slight hone
.25 over oem ITR pistons and rings on gsr rods

Stage 1 clutch, probably comp clutch
3" or so intake, undecided on brand
Cams - thinking blox type a on true time gears
Blox 4-2-1 header
Apexi n1 catback
S300 in a p28 with a tune

Sounds like a decent build. I would use a different clutch though. Maybe a stage 2 or stage 3. Those stage 1's are no different than an oem clutch and in my experience, they wear pretty quick.

I would ditch that header and go with a tri-y replica of some sort. The price should be about the same as a Blox. On another note, I would also use JDM B16 pistons, as these give you a bit higher compression. With an S300, you shouldn't have to worry about daily driving and reliability.

Looks like a sound build. You could even go with some more aggressive cams (even as aggressive as Pro1s..possibly Pro2s) since you're going to have some decent compression and should be a well-flowing head.

I second the sentiments stated on the header above. For the money, the Skunk2 Alpha is hard to beat right now.

You might want to look into ITR intake valves. They're known to flow very well and there aren't any aftermarket valves that have been shown to outflow them.

The only reason I said blox 4-2-1 is because I already have one from before lol. Maybe I'll look into new cams then.

For everyone PMMING me, HT limits me to like 3 PM's since I'm a new member, so just email me at mitch.stahm@gmail.com since it's always full.

i legit have almost the same setup in my car rite now except im running supertech flat face valves and stock itr cams. A 3 inch intake is nice id look for a slightly bigger throttle body if you dont already have one im running a itr thats ported out to 65mm to match my skunk 2 manifold with a 3 inch intake and id get a nice try y header with a good flowing exhaust setup and ditch the blox for some pro1's or something like that never been a fan of blox products lol

thenoxus1

What kind of power are you putting down?

thenoxus1

Will I make enough compression on ITR pistons to support skunk2 stage 1?

allmotorRyan

havent dynoed it yet ive seen stock itr's make 180ish remeber numbers arent everything unless there track times.Also pro 1's will be fine with that compression.

thenoxus1

Sweet, it'll all be tuned by John of Evans-Tuning in PA

anothersickhatch

The Stage 1's will be fine. I'm not too sure about the Pro 1's though. Those cams usually perform better with higher compression.

selling my p30's

thenoxus1

How much?

thenoxus1

What pistons would you recommend then? That was my thought, that it might be a bit low

thenoxus1

So I picked up a set of Skunk2 Pro 1's at a real good price, and my cam gears should be in today. Looks like I may be grabbing a Skunk2 Alpha header, the perks of being a dealer lol

thenoxus1

Grabbed jdm b16 pistons. Should net a cr of 11.5 or so. I was advised to have them coated like the ITR kinds are. Anyone know where I can get that done?

anothersickhatch

I wouldn't coat them. That's just me though. That sounds like a good plan. I had a very similar set-up to this.

thenoxus1

Oh okay, awesome. My only fear is managing to pass emissions. Shes a 99 so with hondata, it's going to be a pain.

anothersickhatch

Just be sure to hook up all of the EVAP system. I think that a good catalytic converter and tune will get you through it.

thenoxus1

Here in PA we have yearly inspections/emissions. For an OBD2 car like this, they actually will scan the ecu. I know with Hondata it won't work since it's OBD1 right? I guess I'll need to swap in my old ecu and hope it runs enough, or just get a ..dirty...inspection. Cams should be in wednesday, I can't decide on what intake to get. Valve trains hould be in in a week, and I'll repull the head and install that then.

anothersickhatch

Ouch...I don't think that using a stock ecu will get you to pass emissions.

thenoxus1

This will be interesting come July, when I get inspected again lol. Anyone in PA own a shop and wanna ..inspect my car lol

ballinboosi

depending on what part of PA you should be good. I know were I was in PA they just checked to make sure your gas cap had a good seal, that was their "emissions". Gotta love TN and no inspection whatsoever.

thenoxus1

Around here they have to hook it to the OBD reader since it's post 96. I can't really find many ways around that, seems like I don't qualify for a tailpipe test since it's OBD-able. Where in PA where you. The fact that I have to deal with this every year is dumb. i will probably qualify for a 5K mile exemption thsi year, since I'll do thus build over the winter and not drive it too much. But beyond that, I drive 25K a year lol. I am a bit over a limit. I guess maybe I can wire a dummy ecu somehow to trick that reader, or somehow find a shop that isn't very strict if I pay cash.

SteelcityLude

i also live in pa, allegheny county its one of the most strict in the state. it is very hard to pass emissions here, either put your stock cams and an o2 simulator or a cat on and run your stock ecu when it comes time,

or make friends with someone at a shop and have them hook someone elses car up to the machine, we used to use our shops work truck on friends obd2 cars that wouldnt pass

or take your cluster out and wind the odo back until your under 5k exempt lol

ive been hearing about dummy obd2 ports for emissions search around. one of the guys that comes to our car meets works at sarver performance and did something with a dummy ecu and got his 500+ whp 3rd gen eclipse to pass

thenoxus1

Anyone in the York, PA area got a hookup? I'm not due until July, but it worries me, lol. I'm decent at wiring, maybe I can rig a fake ecu..
