Well my very first run on the Dyno was 254HP with 263 tq at 13 psi running insanely rich so we'll see on the next tuned runs when I get back off ship

hey good luck with your build Martin, haha your impatience is like none other. I know how you feel having work done to your car while deployed and expecting to come back to a running machine. It's a damn shame that you're experiencing all of these misfortunes trusting other mechanics.

Okay bad a good news...My felpro headgasket decided it didnt like being in anymore. somehow from first to second dyno numbers went to 430hp and pushed the headgasket out. They were tinkering with my boost controller and tinked wrong. Now its off for a cometic gasket.

No since the head and block where both done less than twenty miles ago. I just hope that it seals properly since Ive heard some people have had problems. I think that they turned the mbc the wrong way or something cause the wastegate is 15psi spring and my boost gauge reads up to twenty and they said it was buried. so my guess would be I hit around 27-30 psi "if" I gained 10hp per pound of boost

I did that 1.1 miles into my first kadet build. I turned the knob all the way in the wrong direction and had mine boosting 30+. I blew out my ringlands on all 4 pistons. Headgasket was perfect tho! Is the shop comping u anything???

I dont know about comp, but they did forget the bov they gave me. and the final psi it hit was 36, says the dyno man. they pulled the head today and everything but the gasket looks perfect.

no Idea on the afr but Ive heard my injectors run out around 380. I saw the headgasket today and it was bad. the rings for the cylinders were cracked and pushed to the water jackets which destroyed even further. oh as for comping me they said they will put on my aluminum driveshaft, tension rods, and sway bars, and turbo timer for free. big woop though that would be a fun day of easy

well they did make me one off intercooler piping that has my bov on my hot pipe which is exactly opposite of what I asked for and my beautiful paint job is now ugly so be ready for a remodel. I will probably reweld the bov flange to the cold pipe and then wrap it all in white and black exhaust wrap. some cool looking design or something. but this is all if I get it back any time before I die. its been like six months. I gave it to them cause I didnt think I had time before I deployed to finish the intercooler piping and tune, but I def would have had it done by now!

Newest update.... my head was put back on yesterday and all was good except my clutch slave went out and my 2nd starter since its been there. but the cometic gasket is holding perfect and the car is running amazing. the dyno man told me he has 296hp at 11 psi. That almost sounds to good to be true, especially since I havent seen anything proving it. as soon as I get the print out of it ill post it. mean while Im looking for a ls1 for my coupe.

okay news is my new starter also got burned up but now we got that issue resolved. dyno runs stopped due to headgasket leakage, again, through a water jacket. the shop decided to torque down the headstuds more and snapped one. so now I have headstuds straight from the dealer and a headgasket to most likly replace my cometic. right now they have just removed my arp studs and put the oem ones in to see if they get a seal. monday the dyno will hook his fancy dancy machin up to test for leakage. my fingers are crossed.

Sounds like you have alot of money into this project BUT you have some dyno shop messing with your head and sounds like they dont know what they are doing. Also 296 on 11psi, not gonna happen on that sohc. What compression pistons are you running and what have you done to the head...What are they torquing that head to also if youve gone thru 2 head gaskets in like 30 miles. Also what cam are you running and whats your timing at and are you using a stock cam gear? Did you have your block square decked before you started the build? Did they machine your front cover down with your block?

first of all the dyno shop isnt the one doing anything. he just puts it on and drives. the car shop to remain nameless untill my car is done is the ones ****ing my stuff up. as for the block yes it was all done correctly. and as for 296 at 11psi, like I said it sounds to good to be true and i would post the final dyno pass. but to me it sounds reasonably possible. I have stock cam and head was just rebuilt with a little beafier valve springs and a valve job. there is nothing special up there. its being tuned with aem ems. I only dropped it off there for intercooler piping and to figure out why my emance ecu wasnt working. its been a long time since then, 6-7 months. this shop sucks I should have done it myself, but to be clear the dyno shop has no role except tuning and letting me now what the other shop is trying to hide from me.

Gotcha. Why didnt you do more to the head and an aftermarket cam and adjustable cam gear. Sounds like you spent to much on the bottom end and not nearly enough on the top end, thats a waste of money.Why in the hell would you change from arp head studs? Good luck with it but it sounds like the machine shop and the mechanic shop are taking you for a long ride down a dark road. Let me know exactly what was done to the block also if you dont mind.

block was decked along with timing cover and checked for cracks also bored 20 over. the reason for the headless work is at the time I couldnt find a cam and from all the other sohc ive seen turboed the head seemed not to be the week point. also im not looking to make 700hp just a nice 325-350ish. This shop that has messed alot of my **** up has takin me for a ride but luckly they stopped charging a while ago. also just cause I start driving it doesnt mean all the work is done. for the record I am repping the machine shop and dyno just not the speed shop. oh and me switching from the arp to oem headstuds is because Im about to do my final ship op and then im off to sea for 6-9 months so I dont have time to wait for arp to get me some studs. and plus Id rather they broke a set of oem on this cometic gasket then another set of arp. which by the way have been ordered and will get here too late to install. how far away is hesperia from pendleton?

okay today I went to the dyno where the shop, not dyno, meet me there to replace headgasket. after we replaced the head bolts the cometic still leaked but very little. the leakdown and the compression tester did not read a leak but the head and coolant tester read that it had one. so the dyno guy says when hey does cometic gaskets or any other metal ones hey will run the car till operating temperature and then let it cool. he does this 3-5 times and he usually gets good results. so we will see tomorrow if ive got a good seal. i really need to get that tester he has. it looks like a turkey baster with different chambers in it but when it reads exhuast the fluid inside it turns blue. I should have took my car to the dyno guy, his shop is way better and he atleast knows what he is doing. Oh and the car sounds amazing

Hey bro sorry been busy at work, im a mechanic and have been swamped with engine jobs lately. Im about hour and a half to two hours away from you. Let me know what pistons you put in there and how much they decked your block and if they square decked it or not. Im pretty sure of the reason you keep blowing the head gasket. I did an n/a build on my ka, i square decked the block, milled .030 off the head, ported and polished the head, aftermarket cam and adjustable cam gear, removed the butterfly system. I also think i know which machine shop you had all your work done at also.... YOU SHOULD NEVER DYNO YOUR ENGINE UNTIL YOU FULLY BREAK IT IN.....

forgot some things. were is the head gasket leaking?(on the side and coolant running down the block or is coolant mixing with oil, or coolant in your cyliders) did you have the head pressure tested? If your compression test is good and your cylinder leak down is good then you more than likely have a crack in your head, but with out me looking at it myself and diagnosing it for you i can only advise you on what can be happening.head gaskets dont go out that often and that soon unless you have another problem and they keep telling you its your head gasket, unless you have way to much compression under boost which is a very good possability, which is why i asked you what pistons you are running. One more thing what is your timing at? Let me know and ill help you as much as i can.
