Guest boostthis Posted January 14, 2006 Report Share Posted January 14, 2006 ok my name is eric i live in eastern washington i was givin a 75 504 GLD and i love it to death it runs great but the performance of the n/a 2.1 L wasnt up to snuff for me i work for the local john deere dealer so i just happen to have access to a small garrett turbo off a 2.9L 3 cyl tractor i put it on and the performance increase was pretty good but its running 15 psi boost i have read and have been told that im gonna blow it up with that much is it ok? is there a thicker head gasket that i can put on to lower the compression so it will live its my daily driver... also is it possible to "turn up" the stock injection pump i know my motor is in good shape it fires right up no matter what the outside temp no smoking unless i really get on it hard but then its just a little puff i want it to smoke a good amount until the boost kicks in also what is the firing order because i also have access to an injection pump from a turboed 4.5 L it might be cool i dunno yet if the drive will work becasue its a gear drive i dont wanna spend a bunch of money because i am building a vw bug autocross car and i need to spend money there also is there a 5 speed tranny the will bolt in my car or higher ring and pinion that would give me lower rpm @ 70 thats the speed limit around here and since im gettin more power i could get better economy if it wanst tached out all the time any help would be apreciated please email me @ [email protected] Quote Link to comment Share on other sites More sharing options...
Guest Posted January 16, 2006 Report Share Posted January 16, 2006 Don't mean to be rude, but it would be much easier to read if there were dots, capital letters etc. You don't need a thicker head gasket or any other form of compression ratio altering with a diesel. Just keep your eye on the engine thermometer, because the thermal load of a diesel engine increases as you increase the boost & the feeding. The firing order is almost certainly 1 3 4 2 as in any other 4-cyl. Check how the fuel lines are at the end of the distributor pump, I assume it is a distributor type. It is possible to increase the fuel feeding, but mainly black smoke means just unburnt fuel -> you need more air to the engine -> increase boost. Some guys here in Finland drive their vdubs with 1-1.5bar (15-20something psi I guess) boost, completely stock engine. Quote Link to comment Share on other sites More sharing options...
