Get a converter which converter it`s the best ?

You'll get lots of opinions on that question. I went with a 3800 stall/2.7 STR from midwest, and it's like a new car. Definitely a mod I should have done first. Converter, cooler, and transgo all in one time is the way to go. I also installed aftermarket billet servos at the same time. And by the way, the transgo isn't THAT hard to do by yourself - don't let the instructions intimidate ya!

Midwest's the most reasonably priced, Yank's probably the best, Vigilante's good also. Tbyrne or Yank's websites have a bunch of useful info for selecting the right one for your setup.

[STREET/STRIP]SUPER YANK 3500 stall 1.6 STR what about if i put this on my car ?

03-27-2004, 09:33 PM
I personally would go with a higher STR, but that's just me. Mainly cuz I drive mine on a pretty regular basis. 3500 is about as low as I would personally go too. Just my opinion.

Ya know, from the mods you listed I'm surprised you don't have a whole bunch of KR.

what do you mean with the KR ? ...ok what about if i use the SY4000 ?

Knock retard. Aftermarket MAF and Hypertech on a 98 seems like a good way to invite KR. Do you have a scan device?(autotap)

Did you get the PM i sent you with Dennis's email address? What are your goals?

i dont have the auto tap ...ok what do you think if i change my car computer & put 1999 computer with predator tuning ?

That's not really an option man. You NEED to get a scan tool. I'll bet that you have some KR with your setup. You'll need a setup like LS1 edit to tune and get rid of the KR. Seems like most 98's have KR when they shouldn't. I know that mine did.

I would get a converter. Put the stock maf back on. My 98 has no KR even with the HPP3 tuning. 98's are less likely to go lean. They run richer from the factory than other years in most cases.IMO Aftermarket Maf's are a total wast of money...

Definitely a converter for the mod, but I agree that you need to make sure you aren't getting any knock retard too. Junk the GMAF and HPP3 and get a custom tune along with your converter. I personally like Yank Converters, but my car came with a Vigilante 3200 in it so that's going to stay in there for at least a little while. I'm looking at replacing it with the YPT4200 or SS4000. Give them a call with your car specs, weight, dyno results, and what you want out of your car and I'm sure they can help you pick the right converter.

Another vote for a converter..I have the ST3500 Yank with a 2.5str..I am happy with it..

3500+ converter

dont forget drag radials for street use and for real fun ET slicks on the track.

you put a 3500 stall in with street tires and you're gonna pickup alot of laying drag tickets (with traction control on) lol.

damn the man i took my nitto's off and they are nearly (wet dangerous) wore after 4.5K miles.
