More Power!

I was given a 1985 300D to drive as my first car, but i have somewhat of a facination with speed, so this car just wont cut it as it is. I am looking for anything that will get me more power out of this car. Anything is a help. I have even thought of throwing a crate engine in there, but im not sure what will fit. If anyone knows about doing anyhting of the sort please tell me.

Thanks,
Steve

I have seen that body car with chevy v-8's before, but I don't think there are any kits for such a conversion.

If you want to get the most out of what you have, you can make sure it is in proper tune and the boost is to spec (it is often below spec).

If you want a little more, then I understand that propane injection in diesels works much like nitrous injection in gas engines...

Thanks.

I heard of that. I have an aquaintence who threw a rod with propane, so I probably wont attempt that. I also looked for a new turbo without any luck because I could only find extremely large ones that would also probably blow something out. Also, do you have anymore information about the V8 that you know of? Like size of engine?, cost ifthey payed for it to be done?, if the rest of the drive train was able to support it?, and if there were any major chasis modifications needed for more space?

The only reason I am aware of the conversions having been done is because I have seen conversions for sale occasionaly.

The drivetrain is more than likely able to handle it, especially since it is basically the same transmission used the the Porsche 928. The Porsche has a different case to allow for the rear mounting and diffenential integration, but the innards are mostly the same. Some 928 tuners have claimed 400+ rwhp without problems.

If I were to do a chevy conversion on any car, I would probably want to use the R700 transmission with the locking torque converter anyway. This would simplifly installation, leaving only custom mounts and a custom driveshaft.

If you want a car with more power, then why don't you just get a car with more power? A conversion could cost several times what the car is worth, and create alot of downtime. Something like an 80's or 90's Mustang offers impressive 0-60 times, plenty of tuning options, and is cheap to buy and repair too.

I have thought of that too, however, I live in the S.F. Bay area and I am a young male driver and insuence will cost a fortune for me to pay on a car registered as a V8. Im just trying to consider my options and fine the cheapest overall was of getting a pretty fast car, and I just dont want to go for a rice rocket.

Thanks for your help.
Steve

Hi Steve,
Your 300D SHOULD do zero to 60mph in aprox 14 seconds IF everything is functioning as the FACTORY intended.
Make sure that you have a clean (or NEW) air filter
adjust your valves to spec (required every 15,000 miles)
run DIESEL SPECIFIC OIL and change it hot and often
Clean the "banjo bolt" fitting at the rear of the intake manifold with carb cleaner and a pipecleaner. it should NOT be clogged!
Make sure that the vacuum line from the banjo bolt to the trubo boost wastegate on the firewall is also clean.
Same with the vacuum line to the top of the IP (injection pump) at the ALDA...........some further research on the ALDA will help in the future....HOWEVER........BEWARE AND BE VERY CAREFUL!!!!
There are some other things that can be done inexpensively....ie; bumping UP the MAX turbo BOOST etc.
If you really MUST have a FAST car, then perhaps you should just SELL the 300D to someone who knows just what a JEWEL they happen to be.
Best wishes always,
Spo out 8)
By the way..............please do NOT peg the fuel and BLOW up your new jewel.
Also you need to check timing chain STRETCH and ensure correct fuel delivery timing....ie; the drip method.

I have heard that there is some vacuum line or slenoid or fitting or something on the california edition that can be removed for more power. Since mine is a calif car, can someone tell me if this exists and how to take it off?

I am familiar with disconnecting and plugging the lines to the passenger side on the 603 engines, but cannot say if the same applies to yours.

I thought you might be interested in this...
