I am interested in the conversion i have a 91 auto that i want to swap .I can see the differece in the cams but i am not going to let that stop me.
my car has some personal value that i dont want to part with so i want to swap instead of sale. Can anyone tell me if there is a place that can perform the swap?
Best Motoring VTEC Club video has a whole segment about people doing the auto-to-manual swap. Apparently it is a popular mod in Japan. But Larry is right, it will take a lot of $ to do. The most popular swap according to Best Motoring is to swap in the 2nd Gen NSX-R 6-speed. You will need:
NSX-R Input Shaft
4.23 Ring and Pinion
91-96 Clutch Kit
Clutch Master Cylinder
Clutch Slave Cylinder
Clutch pedal & parts
MT Gauge Cluster?
Probably more that I'm missing.
Both Tsuchiya and Hattori commented favorably on the swap after driving a modded auto car (a KSP I think) and the car lapped close to the NSX-R on the Ebisu circuit. But bring your wallet, dude. It's at least ten grand in parts plus labor. Since you're in PA, LarryB probably could do the swap for you.
well the reason why that swap is popular because they sold almost as much autos as they did manuals in japan. The tuners wanted to start with a car that is less likely to be molested with lower miles ( an auto car ). But if you look at that how much work was done to make it match a stock R and also that they need I/H/E just to match the stock 5 speed baseline hp and things starts to look really silly. Sometimes I don't understand how the japanese tuners think.
This is usually true but if he would be purchasing a 40k+ vehicle he'd be looking at several thousand just in sales tax; something to consider.
40K vehicle? unless he is talking about a NA2 than I don't see a NA1 costing that much. For a NA2 6 speed, than the difference is even greater if he just did a tranny swap. It will be a 250hp, 7000 rpm, less aggressive cam, and .2 liter smaller than a legit NA2, 6 speed.
All Autos came as a detuned 3.0 liter engine, so you can have a 2005 NA1 techically if you bought a auto.
I just came across this section in my Japanese book where they explain the swap (ok, show pictures, that's the only dimension I understand in Japanese books ). It's costly and no way with completely new parts IMO ($10-12k). But as Nuno says: if you can part out a crashed manual car and get an used gearbox it can make sense (6-7k minus selling the auto gearbox 2k? = $5k). It all depends on the price difference between an auto and a manual. It's certainly interesting in very small markets where there are a lot of well-maintained autos but near to none manuals that has not been rotten down to its knees.
Back to my engine question: An auto offers the same level of torque like a manual I've read. The only difference is the rev-limit and the cam profile. I guess that both engines are par below VTEC. Above 6k rpm there's a slight advantage for the manual. If you throw an MT ECU in a converted auto-car what would be the difference? None below VTEC and maybe 10 hp in VTEC?
