ZLadie..

You going up there tonight? Get into the 13's yet??

No, I wont be there tonight unfortunetly. Wish I was there. no 13's yet. I def. should be at 13.9 with this setup though. I hit the 14.1 boucing off the rev limiter once and with a 2.2 60'. I think installing the MRev2 on top of the spacer recently leaned me out quite a bit (i knew this would happen, i have a non rev up and am getting a tune real soon) and I def. notice I lost some power up top.

BUT i am getting a 3.5 rear end next week and I'll be back at the track and should be in the 13's for sure then. I am also getting a UTEC and a good NA tune at Performance Factory (Audible Mayhem) before Jan 10th..(when the local track reopens, tonight is the last night, should be packed.)

Thanks for your interest!!

I saw you run that 9.2, your car is sick... :D :D :D take me for a ride in it one of these days.

You got it!!

Better not rain today dammit..

bad news, the oil was leaking cause the banjo bolt on the oil return line on the passenger side snapped in half ?????? WTF, so now half of it is broken off in my oil pan and i will not have time to fix it...




track isnt open until jan 10th now, sucks but i guess i will take a little break and come back swinging!!


thanks everyone for being soooo cool!!

sorry to hear that. Wonder what could have caused that bolt to snap in half?? Well enjoy the time off and relax a little. You have kicked a$$ so far with this project!

i dont know what relax means?? :icon38:

^^ it means spend time with family, girlfriend and watch pinks! lol :)

Those bolts really suck. I had the same problem with my friends Prelude once. Stupid bolts. Good luck anyway. January 10th will be here sooner then you know it.

its just weird cause i havent touched that bolt in a long long time, its huge too , like a 21 mm if i recall correctly. cant imagine it just breaking off??



i am about to pull the motor out this week and break it down, i need to replace the cometic headgaskets. i figured out it was blowing coolant out of the overflow, i thought it might be the way i rerouted my coolant lines and there was too much backpressure through the radiator, but its actually the headgasket messed up.

it will be back really soon though, im not worried. its never even got hot or even close to hot so the head and block will be fine, plus this motor was built by someone else a while ago, you all know the story on project swap and i want to break it down and change a few things that we now know should have been different.

i will keep it updated for sure, have a great holiday!!

Bump..

10th in a few days :D

stupid cometic headgaskets....



engine is at machine shop right now, i will have an update soon, thanks for asking though man...

haha, same here. one of my heads were bad from when i had some issues before. my car is apart and my heads are at the machine shop. i bought a set of bad ass heads and am going to put a shortblock together for them, but in the meantime run the stock setup and go for some low 11's still...

hey john, what machine shop are you using??

Just an FYI, the Cometic headgaskets are engineered to be just a bit better than stock, not all that much superior. The Cometics are designed for OEM replacement where the mating surfaces might not be 100% true and are made with just a bit extra thickness to seal up nicely. For a real application you should look towards a multi layer copper headgaskets, the HKS one or perhaps "O" ringing the block.
The whole Cometics brainwash on this board is absurd IMHO. Seems like the sheep follow the shepard on this board.:p

I would definately go with the multi-layered steel type for a gasket. You might want to consider larger head bolts as a "while i am at it", to keep the heads from lifting...

yeah i have some serious plans for it to keep the heads tight


i never would have used cometics but it was on the motor when i got it...


you know the story


running 8s yet mike???

Aint that the truth....

I am out of the loop for little while. I was hired as a First Officer by Pinnacle Airlines and I won't be able to run the car for a couple/few months while I complete ground school. I installed the 1600cc injectors and 5 bar MAP before I left, but didn't have time to do any tuning...:rolleyes:
Mike

would it be sacreligious if i just put a LS2 in my car??? hehehe


still debating what to do...

:eek: Yes, it would! :icon22:


Just kidding. I'm sure whatever you decide to do with the car will be awesome. :cool:

You could drop in a supra motor like Z-Gad! :D

Jeremy, what would be the benefit in putting in a LS2 over the built motor that you have for your Z now? The motor you have must be able to put down about 900whp or so with a good tune and maybe a little nitrous. How much more would you be looking to get with an LS2?

LS2...... I like the idea and I know just where you can get one, from me of course:icon38: You should get the new LSX block and go from there if thats what you decide. Here is a good link as to what guys are doing with the LS series engines http://www.w2wpowertrain.com/t-Casper-2.aspx 6.82@205 with 352 CI block. Its bulletproof and is the way most people with a GM platform will be going. I like the Z though and if your going to take it that far in all honesty your current platform would have to be completely reworked or you may have to get something lighter with a larger selection of aftermarket parts then the Z. Either way good luck and you have lots of fun/work ahead of you.

i duno .. it might be me but i think some guys on this board like jeremy want to see how far they can take the Z and the z motor.. just thought maby :icon14:

you can get 600 easily all motor out of a LS2. then if you add some power adders, 1300-1500 is very possible.

i am expanding my business to some other platforms now, the LS is the direction i am headed.

i will probably keep the Z motor in mine and put an LS2 in my G35. that was the plan originally anyways.

i like to change things up, i am going to be getting rid of the Z here soon and purchasing a GTR when they come out.

see what i can get that thing to run...

Wow, I wish I had those kinda options. Good stuff. Not that I wouldnt like to see a LS in a 350Z/G35 platform, just curious what your reasons were since you already have such a good platform. Obviously there is a larger aftermarket to make some serious serious numbers with an LS motor. Good luck, cant wait to see that.

BINGO!!

LS2 in G35 would be SICKK!:icon16: :D

By the way Jeremy, I raced the Red auto Z that recently had the UTEC/tune and dynoed at 256rwhp. He had me by about 2 car lengths, I kept up pretty well....it was fun.

yea, the race was so good he didnt wanna stay for the rest of us. lmao jk.



As far as the LS2 i mean, yea its a sick motor. But i mean after seeing Zs get to 700+ hp levels built with the twins. I mean , what more could you ask for . I guess the potential is what i see would be the advantage with the ls2 and making more power more easily because of the displacement etc. But , im all for innovation either way. To me after seeing this vq http://www.houston-imports.com/index...d=62&Itemid=35 and seeing other doing this much to the vq you cant really go wrong either way . Good luck either way man. lol

yeah i am still not sure, i might have a pretty cool surprise... probably do the LS2 swap in the G35, but still not sure what route with my Z i am going to go

I would think that you would want a few more passes in the Z with your current setup though. Its not like you got to get enough passes with the new tranny yet. It would be interesting to see how deep you could get with your current setup!

well.... cometics + 17+ PSI = blowing boost through the coolant


which in return gets water into the oil , this water in the oil gets on the main bearings and well... game over :(


crank is done, block is done, mains are done. live and learn. i am starting back over with the short block, not sure what i am going to do though. i will keep everyone informed though.

if anyone thinks that they have any kind of head gasket leak, dont drive the car at all. we are looking at finding some oversized bearings and possibly line honing the mains and see what we can do but i dont want to put it all back together and try to run crazy boost until i know it will hold it. thats why i am not sure what i want to do right now.

i say stroke the ***** MORE POWA lmao jk. Also did you get the s techs in?
either that or do that titan swap that would be awsome.

yup i have the stechs in, i am checking now on a couple sponsors on stroking the motor and keeping it all motor, i am going to put a LSx in my G, thats pretty much the plan right now.

still up in the air, except for the NA/nitrous combo on my car, thats pretty definite

So what is going to be the setup on the NA/nitrous motor though? Stock Long block, or cams w/...

I was also unaware that you turbo motor was not still together. I was under the impression that it was ok, so I can see why that is not really a consideration of yours. I take it the cometic headgasket didnt seal very well then. Do you think that the machining was just a little off for that headgasket?

yeah the cometic started all the problems, not sure really what caused all the mess, i am doing a custom JE piston 12.7 to 1 with some big cams, probably just use eagle rods.


i will have the pistons in less than two weeks and have it all together here really soon. 12.7 is the highest compression that you can do without any valve clearance issues.


we will see, i will probably run a 150-200 shot on top of it after i run some fast NA times..

u better say when and where, this should be a event for all to vid and see man. U might spark the NA revolution lmao. ..and make alot of people broke, lol happy but broke lmao jk

Im a huge N/A fan, and Im sure Jeremy's car will be pretty fast with a 12.7 compression ratio a good tune, and a huge rev limiter. This is absolutely going to spark a lot of peoples imagination and mine, and end up costing us a lot of mony in the process. I still cant wait. Good luck Jeremy.

The cometic gasket issue also though. I know they are supposed to be really good and all, but it seems as though the shop you send it to has to be 110% spot on with its measurements for fitment or they just fail. My friend built a VR6 Golf and attempted a cometic headgasket and just ended up with a ton of headaches. Seems like its the "right" way to do it, but the success rate, as far as I have seen is really bad.

Jeremy, why are you changing your set-up? I would have thought you would have given the current set-up a little more time to see what it is capable of running. Don't get me wrong I think a high comp. build with nitrous is awesome. We have thought about doing a "big" nitrous build as well. On a side note have you modified or reinforced the rear suspension on your car. We are concerned about it's ability to hold the power/tq we will be throwing at ours this season. Let me know and best of luck with the Z. Jason

sorry to bump this back but i didnt see his question...


basically when my motor was built, cometics/cosworth or stock headgasket were the only choices, well 17 psi and 100 shot blew it out and got some water in the oil, then the 22 psi and 150 shot i tried to run didnt help and it all caused many many issues.


i opened up a shop here in orlando and have a lot of debt now, my car has been put second on the list now, i sold my whole greddy kit installed and paid off a lot of the debt and that was a hard decision but im happy with it now.

so in return i am trying to keep the cost down and build something with just as much respect as the turbo/turbo400 setup brought. 11s on motor will be pretty exciting and will be reached here in a few months.


i dont have the time or extra money (with my new shop) to do everything i wanted to with my car, but there will be time in the near future.

good luck bldrz with hitting 9s, its very reachable with moderate levels of boost. and the rear of my car is just fine, but my car is a feather compared to most...

Good decision.

I really cant wait to see how it turns out. Good luck again with the build and your shop.
