returning 3800 newb

[smug]

okay so I bought the GTX back last weekend and it has been demodded some and I am having a huge KR problem. I have forgotten a lot in the 2.5 years that the car has been gone but it is slowly coming back to me. So I have an L26 block, stock L32 heads, XP cam, double roller chain, 105 lb springs. No intercooler, stock gen 3 blower and throttle body and a .......................3.0 pulley lol. That is exactly the way I bought the car back. The tune is wack right now too. -12.5 LTFT at WOT and I am not sure on the timing because the car gets like 9 degrees or KR.

I am thinking a bigger pulley and some time with the tuner should fixed this KR up.
Or just fuck it and intercool the car and say bye bye to KR
I am gonna go by some new plugs because they are cheap so what brand and what gap pluigs are people running now a days?
Now another thing is that I have a timing commander and I forgot what you are suppose to do to the air temp spark table to get the damn thing working correctly.

i've got nothing to contribute to this thread except a solid hell yeah.
good luck getting it tuned right

turbo,

no wait, TWIN CHARGE to get rid of the KR

no seriously congrats, that was a beast of a car!

ill have to look at my old pcm files for the timing happy knob, basically you put in timing values for a given rpm based on whatever temp you set the knob at and then use that row in the pcm bin file

i vote for going with an IC

and i'm currently running NGK TR6's gapped at .050 and all is well

 

[Ron Vogel]

Yeah, hate to say it...but that thing needs an IC. If you want to go cheep..then just do E85 and it's all good. At least if you decide later to IC it you'll have the fuel system (beefed up) for it.

TURBO

3.4 pulley on 93 and get it tuned OR get an i/c. I'll bet with actual tuning you'll do a lot better than you did 2.5 years ago. Going to the track in October/November?

The thing about E85 is that there are almost no gas stations out here with E85 pumps

You serious about a 3.4 pulley with XP cam and headers?
I ws hoping to go with a 3.25 but I guess it does not really matter all that much

Well 93 octane blows balls, you'll never get any timing out of it with a 3.25 PLUS, you have high compression, not good for small pulley's on pump gas. If you want to go E85, then that's a whole other animal, but i wouldn't go smaller than 3.25 with E85 either. The 3.25 with an actual tune on E85 would walk all over the 3.0 pulley and a tune i'll put money on that. If you toss on an i/c again this conversation would be different. Therefore make up your mind, an i/c or turbo kit.

I am pretty sure that with the Caspers timing know I just 0 out the whole table and the timing know does the work. It know adjust from -7 to +7 and it does not go off of temp from what I see.

Awww shit

I like that car, its great that you bought it back. I try to keep in touch with the people who bought my cars, even asked to buy my TA back LOL.

If the IC and Gen V is gone already I wouldn't even fuck with gen 3 M90 shit. Buy that $1500 cartuning kit HK talked about. For now I would just start with a fresh tune and work on it. Put a 3.2 on it to start tuning. Does it have the same tune on it from when you had it, or did ZZP get ahold of the car?

 

[PANDA]

Wat u mean no E85 Dan??? Walk down the street, grab some corn and stuff that shit into the gas tank. INSTANT RACE CAR!

 

[DanJ]

A mixture of corn syrup, and corn flakes will also work.

there is a 700 dollar CT kit with a 60-1 turbo that needs rebuilding, or just upgrade... not like a 60-1 cant get you 11s or anything

also, making a IC kit for a same side TB is pretty easy

 

[Yaj Yak]

turboit.

 

[smug]

no GMR 1 inch chain
bad for turbo?

 

[G_T_O]

turbo it! i wanna turbo so bad!!

 

[99PONTIACGP]

Someone say turbo? :smile:

 

[Handsome Jesus]

that $700 CT kit is junk. turbo totally shot. would only be worth it for the piping. and I give that a price of like 450.

 

[G_T_O]

that kit seemed to cheap to me when i saw the post up there!

7/8's chain plenty for what we do, into the 10's would require a 1" chain, but that's still arguable. The 60-1 is the best turbo in the world and it's perfect for the higher compression. No need for a 67 or any of that. I would say at 14psi on the 60-1 with the l26 and an xp cam should put you right at 11.8@119mph with a crappy 1.81 60' because you didn't do a burnout, also you had to let off the throttle completely to get the trans to shift into 3rd cause it's all goofed up. I predict that, just right off the top of my head

ordered a 3.3 pulley
took the front header off to weld up and small hole
any one remember the table for the timing commander?

I have the same set up but use the s1x cam and gen v blower, but mine made 280whp on 93 with the 3.4 pully I would say try the 3.3 with the gen 3 and tune away
