Time For The Single/Stinger

[apexi287]

Well so much for any good news that was going on. Everything has been going ok, but I got on it again today and it instantly started missing a little at idle like it's done a couple times before. The cyl. #1 plug has gotten fouled out bad a couple times with gas and carbon and I thought the culprit was a faulty injector since my A/F were sometimes going from lean to rich at idle but always settling on a perfect 14.xx, acting like it was sticking. I pulled the plugs and once again the #1 plug was all fouled out but smelled more of oil this time.

I did a compression test and got the following...
50psi, 145psi, 150psi, 155psi, 150psi, 145psi

Followed that up with an oil drop test to check the rings #1 didn't change, so I did a leak down test. Sure enough hissing out the exhaust valves. I have a feeling when the timing was a tooth and a half off and I slowly began to rev it to 7.5k the valves floated and touched. It still drives very well which is so weird, it'll only take a crap after a good couple pulls.

But looks like she'll be parked for a little bit until I get time to mess with the head, I'll keep you guys posted and if anyone knows where I could find a good head let me know. I won't have access much anymore to grinders and a valve lap machine so I don't think I'll rebuild this head just yet, I'll just hopefully find a good replacement for now:3d_frown:.

Sorry to hear about that. Good luck with it in the future.

I agree hopefully you can get that sorted out.

Hopefully soon, thanks for all the help guys. I'm going to try and find a good head for now and slap it on for a while. Look for a 2J block and slowly build a 1.5 on the side. I just need to find a head first.

Well just a little update, my head work is getting finished up today. I decided since I ended up with some damage to a piston in my bottom end it was going to be cheaper at this point in time to go with a 2J bottom end and swap that in.

So that's the weekends big plans, I'm getting the head today and then hopefully getting everything re-assembled and back together this weekend. We will see how it goes, hopefully the weathers nice:sarcasm:.

The engine bay is almost done as far as painting wise which I decided to do since I pulled the engine back out, and I will also be getting rid of the ABS to clean some things up:icon_bigg.

Well the 1.5 is now complete got it all finished up saturday night:sarcasm:. It feels amazing, at 15psi it pulls like crazy:aigo:. As of right now I just need to fine tune some spots on the map but it's running very well with great gas mileage and good hard pulls.

Hopefully within a couple weeks I'll have everything tuned in at 20psi and then throw her on the dyno and see what she does. That extra .5 is like a 1J on speed:naughty:!

i love this thread, glad to hear u got everything worked out.
my dyno graph looked like urs, when boost kicked in, it was all over the place...gonna check all my ignition components.
figured out some little problems that i had looking at ur thread...great job btw
oh, and what else did u actually need besides the block for the 1.5 jz...thanks so much, u gave me motivation to finish up my ride...

Thanks man glad to hear I inspired someone in some way. I was finally able to get her back up on the dyno again yesterday. Shes still a little fat up top and after about 5 pulls fouled my plugs which called it a day.

My wideband took a shit on me in the midst of tunning so I couldn't go any higher than 10psi. My timing MAP is still really conservative as I don't have anything yet to monitor knock. I'm just waiting on a new sensor right now for the wideband so she can really start to breathe.

These are the 2 dyno graphs the 4th gear pull is the last one I made of the night, and as you can see plugs started shitting on me.

3rd gear 410rwhp/365rwtq...

and 4th at the end of the night 423rwhp/383rwtq...

This was again on 10psi and really poopy 92 hick ville gas:sarcasm:.

As for the 1.5 all I needed was a 2J timing belt, tensioner and extend the waterneck bypass tube 7/16th of an inch, thanks to suprahero for that info!

Wow this really thread really inspires me to go 1.5jz. Then again it is hard to justify it when my 1jz is operating perfectly.
