Re: Ohisofly’s 91 Si project – 700hp or bust
I appreciate the feedback guys. Good idea with the wrinkle paint to hide the imperfections, I may end up giving that a shot if the powder coating falls through.
If all goes well this weekend I'll start working on the engine again

My brother's civic wagon has the passive seat belts, I agree those are far from the ideal setup.

Re: Ohisofly’s 91 Si project – 700hp or bust
To my knowledge crx's never came with passive seatbelts, mine doesn't have one anyways. Both the shoulder and lap belt is built into the door. I'm not really fond of the design as it's more prone to close the seat belt buckle in the door and mess up the door panel (ask me how I know)

PRETTTY sure its a 90-91 thing the 88-89 has a slightly different panel and seatbelt in the pillar

Re: Ohisofly’s 91 Si project – 700hp or bust
might be based on the manufacturer year. I had an 89 probe gt with the same auto shoulder belt, manufacter year was 7/88, iirc. I **think** the vast majority stopped using those particularly around the 90/91 year (91/92 model years).

I believe it's only 88 crx and 88-89 hf that have pillar mounted seat belts. I hate the door mounted belts with a passion. I'm running 4 point harnesses mounted to my roll bar in my awd crx and my all motor car I rigged up a pillar mount setup for it for the driver side only (track car) those door mounted belts are super heavy for what they are.

Re: Ohisofly’s 91 Si project – 700hp or bust
Got my Delta 272 cams back
New toy
Had to replace a connector for all the wires I added going to the ECU
Cracked climate control
Jb welded it back together and then put this plate on it
Thicc
Used some normal jb weld to fill in the small holes/imperfections (used jb weld steelstik originally). Still need to sand it down
Didn't take any pictures but also got the mig splatter off the 15x10 rims. Mainly just used a chisel to chip the splatter off and then sanded it smooth. Front & rear rims are packed up ready for powdercoating, now just need to finish the valve cover

Pictures not viewing for me, maybe cause I'm on a govt computer, but how do you tie the fuel line into the fuel pump when upgrading to an lines? Do you flare the hard line then use an adapter, kind of like doing brake line tucks? I'm doing this on a 96 civic but sure its similar. CRX looks clean. Here my autocross beater. I just finished the hush kit, pain in the butt finding my shift point and I was actually over travelling too far and the clutch would start re-engaging as I pushed farther. Pulled the dash and readjusted, so nice now. Best adjustment kit ever, Engagement solid and same place every time. On cable XSi trans with hasport slave adapter kit.

so that adapter installs on your an line then the other side clips into the hanger side that has the little quick disconnect, Is the quick disconnect line your supply or return?

The stock gm flex fuel sensor looks like this
And this is mine after using the fittings that Dax mentioned (mine adapt to -8 AN)

Re: Ohisofly’s 91 Si project – 700hp or bust
I got rid of all the stock fuel lines so I only had to use the adapters for the flex fuel sensor. Your crx looks nice, good to hear you like the hush kit I'm looking forward to have a hydro setup now.

Just so you know how much ethanol is in your fuel. It's ideal to have if you're running e85 from the pump to see what the actual ethanol content is as it varies

Re: Ohisofly’s 91 Si project – 700hp or bust
They do sell gauges but I'm just wiring it as an analog input for Hondata. Not sure if I'll be able to see it on my tunerview screen but I mainly just want the ECU to see what the ethanol content is so it can adjust the tune accordingly

can you take pics of what you did at the hanger section? If I am going -6. Did you do as DAX said and just get an adapter to clip into the stock supply hard line or did you do something else, like cut the rigid line and use a 90 degree an elbow? Bout to order all my parts and want it all here so i can knock it out and not look back. This has been my 5 year headache, spent too much time on cosmetics and tucking everything before researching what is needed for my power goals.
Thanks for your time

Sanded down the valve cover
Far from perfect but it'll do
Ground
No ground
Vht primer
Vht wrinkle paint
Was turning out great till it fell off this setup and hit the floor Maybe next weekend I'll redo it
Started working on my setup to degree the cams
Ended up tacking it together
That's it for now
