Is Turboing a n/a a bad thing?

[Rabbit TD]

don't slap on a turbo IP, you'll end up melting the valves and pistons.
but one could use it for a quick getaway (very sparingly) a switch or noob on the dash.

Uhmmm... Care to explain this? They can deliver the same amount of fuel to an engine. I am kinda half sure you would melt pistons with a turned up N/A pump, as opposed to a turned up TD pump, quicker. To get power from an N/A pump you will have to have the fuel screw cranked up to have fueling for when the turbo fully spools, and doing so will give you WAY TO MUCH fuel for when the turbo is not fully spooled. Effectively melting your pistons and throwing a few rods through the block  However! throw a TD pump on there, and with use of the LDA you will be able to govern how much fuel is entering the engine relative to how much boost the turbo is making (how fast it is spooling). Thus you will never have to much fuel, and you won't melt your pistons  Assuming you don't crank the fuel screw up.

Best plan of action.. find a TD pump, find a turbo. run them BOTH at stock settings and add an IC. your car will love you. You've added more fuel, you've added more air, and you've made that air colder. A diesel engine would love nothing more than that. 

That all sounds right to me now I have to get my T/D pump back on and see what this old stock t3 actualy does with what it's designed to work with.

Umm, why?


I could actually get higher egt's with my old NA pump than I can with my turbo pump.  I'm still not seeing past 700* F or so.

Just out of curiosity where do you have the probe for the EGT gauge at?

[hamradio]

Pre-turbine.  It's an aircraft spruce probe.


I could hit egt's of 1300 when it was NA on an NA pump.

The main thing to watch is egt's, keep it cooler than you would with a real turbo motor.

Not to hijack or anything or is it me or was there an mk2 NA rear engine mount that would not accept the turbo oil return its basically cast flat - Ive seen 2 other NA engines with the mount that has dents in the casting for the turbo oil return, Im afraid to grind it as it may crack the entire aluminium when the engine vibrates..

Not many VWs around here

Therein lies the hard part.  Finding any turbo stuff is just about impossible around here.

Looks like your stuck with an N/a

thanks guys i know it not a 83 engine its a 80. so thanks a lot. 

[bevboyy]

been there, done that.

Yes it can be done.

1) Invest in an IC
2) Invest in an external oil cooler
3) Invest in a good set of head bolts
4) Invest in a egt thermocoupler and gauge.
5) Invest in a boost controller.

Points to ponder:
-----------------

You can use the stock ip - increase fueling to compensate - you will see more smoke off line, but you will make more power.

Make sure your EGT's don't go over 1200 degrees at any given time.

10psi of boost is a safe about to run.

Have fun..

Great input. Thanks to all; now I'm inspired to do this!
