I now can get you 4t60-e trannies that are rebuilt brand new units that take 300hp without a problem this is a professional product that has been professionally rebuilt solving all the weaknesses. This tranny just bolts right it. No swap necessary. Cost is around $3000.00US. More to come. Yes the site will be up as soon as I get all the details and forms signed by the companies I am working with. I know when I tell you about this stuff its like a tease. I can though for the eager buyers get anything that I have mentioned within a short period of time (except for group purchases that require at least 24 units to be ordered).

Would there be any way to get different gear ratio options for this?

Definitely have Intense rebuilt the 4T65E if you decide to put one in your car. That'* the guy who has a 12 second 2000 SSEi, he knows what he'* doing.

Now my 4t60-e has been rebuilt about a year ago. Would I need to do a core return or is it still mine and I could sell it. What is a rebuilt 4t60-e go for? It was rebuilt by a reputable tranny shop in the area.

I was seriously considering doing this a few months or so ago. I had a local slavage yard with a COMPLETE front clip of a '98 SSEi with 30,000 miles. L67, 4T65E-HD, Axles, Computer and harnesses, EVERYTHING, for something like $2800. I shoulda jumped all over it, but I didnt want to drop the coinage right then. If it was today I would have it in my garage already I'm keeping my eyes open thats for sure. I'd like to build up both the L67 and 4T65E-HD right in my garage without tying up my car. Get everything all modded and built, swap the motor one weekend and done! I cant really picture it being that difficuilt at all, with the hardest part being the wiring / complete harness and PCM replacement. Heck though, even I have to reomve the dashboard to get to all the wiring... Been There... Done That! :P

I also looked at that option and it is a very good one because it is easy. Make sure you get a "good" engine and computer. That can cost if a mistake is made. You can also buy the 4t60-e beefed up tranny and add a sc from zzperformance later providing about 270hp to work with. Yes you have to add new parts to your engine but it will work and no major swap. That said the hp potential with a swapped 98 sc engine and tranny will give you the ability to go to 450hp. hmmmmm if you are after major hp today then the swap is the best. That said 400hp is very expensive. I am sure the series 1 can be made to run crazy hp numbers just has not been done yet. But the hp range for the series 1 sc kit is.... well read this
"The base kit is designed to work with stock or lightly modified engines. It will make 5-6 PSI on a stock motor and add 60-70 horsepower. On a mildly modified engine, dyno tests showed an increase of 65 horsepower at the wheels (approximately 80 engine horsepower) at 5 PSI. With a pulley swap and a new peak boost level of 8 PSI, the car dyno'd 270 wheel horsepower, or 335 engine horsepower! This is an increase of 135 horsepower over stock! Other modifications included ZZP rockers, TOG headers, custom exhaust and GTP fuel injectors."

From zz Performance.
I was talking with Lee Performance and they said this would be the best way to go.

300hp is easy to get with both engines for about the same amount of $ just have to decide which is best for you. (Oh one other tidbit the computer from a 98 is harder to mess with. A computer from a 90-95 is putty in your hands.

You guys can just buy a L67 w/ a 4T65E from a car with low mileage for less than $3000. That would be more cost effective in the end because there are so manyh L67'* out there they are dirt cheap. You can pick one up with 1000 miles on it for $3000.

And actually the computer from 98+ are better to work with because they give you more control over the car. Plus you have OBD-II which is very handy since you can log your engine and see exactly what it is doing and such.
