Are you running a stock r154 that has never been rebuilt? Syncro's might be showing signs of age?

The thing is I understand what is being said .... but for the people who don’t understand ..... there is has to be clarity. I tune my car for 11.5 but I have the skills to keep my car a live and to fix it if it breaks. I haven't blown a motor since 2005 and I have two mkIII with slightly...

Its funny I don’t recall stating my stance .... I asked a question b/c most people say 11.5-12.5 is the leanest you should run. Then I posted some decent info on the basics of tuning. Then I ask someone who seems more knowledgeable than myself to share his wisdom, and you guys are fucking with...

Nick its a pretty damn good start ...... Would you be so kind to complete the rest of it ..... and continue the spread of quality info.

I was in that area a few times in the lasr few months ..... if it had wheels on it then its me .....

How is 11.5 dangerous?

Very true but that changes if their is a boost leak .....

i live in sandy springs ..... which is rich next to dunwoody :) ..... i drive a pretty supra/super white

Your base fuel pressure is at idle when the car is at op temp reads 46psi????? Thats a pretty high for a lex afm and 550 combo ..... you should be around 28-30psi and you should be pulling fuel out fuel between the ranges of the 3000rpm to 5500rpm (+/-) ...... It doesnt sounds like you know what...

15psi i still to low for the turbo he is using to hit fuel cut maybe a t78 but not a 57trim ct26 ....... Its not moving that much air. Is the adjustment screw backed all the way out? How much vac are you pulling at idle. Whats your fuel pressure at idle?

You didn’t offer answers either and there is a reason. MDC gave him a question to answer did he answer yet? I don’t think it wise to tell someone what they should get until you know what they are trying to do. If he wants a quick spool and no top get a t25 off of a sr20det if you want a top end...

Did you tq the bolts down with a tq wrench and put lock tight on the flywheel bolts???

Check the tranny mounts ..... its one big piece but it breaks down to a few parts make sure the rubber pieces are still in tact and everything is tight.

Tune with fuel pressure first and then fine tune with whatever piggy back and the ct26 no matter what trim wont flow enough to max out your setup (550's and lex afm) .... Again only a dyno session will give the answer you seek. Most people run the upgraded ct25's at 17-18psi but each car is...

LOL Are you really arguing against getting the car dyno'ed? You asked the question, is 20psi to much for 93 octane and I respond the only way to actually know is get the car dyno’ed, anything else is guessing. This is an expensive game to be guessing when you can know for sure what your...

well it would let you know where you knock and make sure the car runs has head room for many things..... each car is different we could have the same identical setup and when go to get tuned our settings could be way different. I may be able to run 22psi while you can only run 18psi.... get the...

good point poodles
