[font=times new roman]Hello, people. This is my first post after nearly a month of lurking.
I have a couple payments left on 1996 G20t, then it's let the modifications begin.:sun:
Since I have an automatic tranny, I am seriously considering having the folks at Level 10 rebuild my tranny with their signature performance enhancements (see
http://www.levelten.com/). I realize that the stock tranny can probably handle boost to about 200 HP or so. However, if I go beyond that say, to 250 or 300 HP), there will likely be problems. For a full Level 10 rebuild, their staff assures me that my tranny would be able to handle three times the stock HP max (or 3 x 140 = 420 HP).
Does anyone have any experience with Level 10 mods? They appear to be world renown with many press write-ups; so I should feel pretty save turning my tranny over to their knowledgeable hands although they are talking major dollars - auto tranny rebuild ($3264) and torque converter rebuild ($498). Ouch!!!
Before I go this far and spend that much money, I could take care of the basic mods: header, CAI & exhaust. I also am considering a lighter flywheel and the JWT S3|S4 billet cam set.
In that regard, i am considering the JWT aluminum flywheel ($495) which weighs 13 lbs. this is about 5 lbs less than the stock flywheel. I figure there should be a performance boost of about 2 HP for every pound saved (or 2 x 5 = 10 HP). The JWT header ($450) would provide another 10-15 HP boost, according to their figures.
Many members here seem to recommend the Hotshot CAI ($215). I will assume a boost of at least 10 HP there for argument's sake. I can add the JWT ECU upgrade ($595) and Pop-charger ($159) for another 15 HP boost. The JWT S3|S4 billet cam set ($560) adds another 10-15 HP boost.
JWT claims their cams require their JWT HD valve spring and titanium retainer set ($600) for proper functioning. However, I haven't seen anyone here talk about using the valve springs and titanium retainers. Are they really necessary?
For the exhaust, I see many people saying good things about the Greddy Evo (I haven't check the cost yet). I will assume at least a 10 HP boost there as well.
All told, I'm looking at HP gains of 65-75 to the stock 140 HP max before consideration of any turbo kit. (JWT is still finalizing their production turbo kit for 1991-1999 SR20DE engines.)
Does this seem like a reasonable approach to the dedicated gearheads here? Is there anything I may be overlooking?
Thanks very much in advance for all comments! :sun:
