I have a built motor in my 3000GT VR4 which has lasted me 50,000 miles, and on my 9.3.1 comp. built motor for the G35 I put on 24k before I took it to GTM and had it built to 8.5.1 comp. The first was my daily driver till I got the G35 and now that is.

 

I was referring to the compression test, sorry. I will be running a 9:1 compression ratio with my build.

I.e.

My Gf's new s2k motor had compression of 210,209,210,210 in her JDM engine, but it has a compression ratio of 11.7:1.

I have looked everywhere from when I had my stock block compression tested, but I can't find the read out. I think it was 180-190 in each cylinder, but it has been almost a year, since then.

Anyway, back on subject.

Anyone with over 30k on a built block, say running a minimum of 13 psi?

 

3k on my built block, 8.5 comp, 10 psi daily driver mode tuned on a UTEC (which sux btw, upgrading to an Autronic unit in a month or so). 1 spirited run per day just to get my daily "kick in my pants feeling," other than that: revs stay below 4k rpms because this sucker guzzles gas like a V8.

 

why stop there, go for the 4.2L

 

So DD is 10 psi...

What is the kick in the pants feeling's psi?

Never heard of the autotronic unit, elaborate

 

Well let,s face it ahn you know you have to much power and you are afraid of it.Let me know if i am lying abought it and i can help you with it.

 

2 UTEC complaints any elaboration?

 

IMO at anything over 10psi it doesnt have enough resolution to tune all part throttle load sites and WOT. Of the two of course you pick WOT, and have a few hiccups during some spots of normal driving. Over 1 year my tune has changed some, and now my part throttle driving sucks and is annoying. For the record this isnt Sharif's fault, nobody could fix this, new EM coming this winter

 

^likewise. Switching to the haltech next week. I'm tired of getting my UTEC tuned 4 times a year.

 

I have no power, I dyno 230whp on a DD That's why I need a EMS upgrade immediately!
I get the "hiccup" and it's annoying like a dam car fart!! UTEC does not stabilize my idle as well as what a stand-alone unit (Haltech/Utec/HKS/Autronic) could do. There are also a few startup issues. I've seen Bambam's car, (I think he's running the HKS) that thing idles like stock! 99% of my driving is done at part-throttle/city driving/stoplight to stoplight crap.

 

Thats why I drive WOT 90% of the time-to avoid the hiccups!!

 

Bert just let me know when you want to put the stillen s/c on that beast of your,s and make some real power.

 

i didnt know that was necessary... mines been running, until recently, with no issues since the day i got it

 

Well unlike Arizona, we actually have seasons and the weather changes haha.

 

3500kms 13psi Fcon, no problems!!! 8.5:1 CP ceramic coated pistons

why are people worried about build motors not lasting?

 

I am not worried, nor do I think most anyone is, but I was just curious, how everyone's engines were doing.

I konw that Sharif's built engine, last time, I checked had nearly 30k of incredible abuse.

 

..what are you talking about is 79º right now

 

I'm right aroung 30K miles on my built engine, daily driven 150 miles, mostly 70 - 80 mph, 2 - 3 miles surface streets, 11psi.

 

That a boy!

 

Is it still running great, what power level? Is it driven in a spirited manner, or lopped around at 70-80 mph all the time?

Good to see a 30k built motor!
