My neighbor is looking at buying a 1991 1-ton dually 2L 2.4 Diesel with a 5 speed. It has 198k on it and is non turbo.

Would this Toyota be worth putting a Turbo on or would it be like putting a Bow Tie on a Pig wearing lipstick (not worth it but you learn a lot in the process and gained nothing from it)?
 
If you run acetylene into the intake, then at least you'd know when it was going to die.
 
Toyota thought it was worthwhile back in the day. Search the 2L-T which is what you're looking to do.
 
I had a toyota surf with the 2.4 turbo(factory) and my mate had a dual cab with the 2.8. The turbo always left the 2.8 for dead. I could get 4 wheel spin with the turbo. To fit an aftermarket turbo there is a bit of work involved.
 
I had a toyota surf with the 2.4 turbo(factory) - had it for over 200,000 kms.

The turbo makes a big difference. The 2.4NA is available here and it couldn't pull the skin off a custard pudding.

The turbo's are common in the UK - loads of Jap imports - you can get spares off ebay all day long. They are all about 15+ years old now so lots are starting to fail.

It may be easier for you to look over this side of the pond for your bits and pieces - I'm not sure how many of these you got in Central California?

Do a search - loads of the UK guys export stuff.
 
Aftermarket turbo kits for these engines are common. You have to be more careful watching EGTs and coolant temps of course. The 2L heads seem to be stronger than the 2LII and 3L heads, but I have no evidence to back this up.

I prefer to keep mine NA though.
 
Dan, the 2L-T was imported to Canada and I think the US got it as well. '84 thru '87 or so. They were in the 4x4 pickups.
 
a diesel without a turbo is only 1/2 a motor (imnsho). Keep the boost low and you shouldn't expect problems (imle)
 
I've turboed one of those before. It was worth every penny of the cost once it was done. But it was still slow
 
I have no personal experience, but if you search on this forum there is NO love for the 2L or really the 2L-T either. Ok, I take that back, there is some love, but most of the grey hairs agree its only a matter of time before the fans get bitten. Head problems is the usual complaint...
 
please buy it and let us know how long it lasts and what part left you on the side of the road bitch'n and complaining about why you ever bought that POS against all common sense.

but then it isn't my money so what do i care...
 
Thats ridiculous, I say turbocharge it. I've got a 93 Dyna 150 with a 2L NA that I'm fabbing an intake/exhaust manifold to a Garrett T3 out of a 740 Volvo turbo. Im gonna stick with the stock injection pump and turn up the fuel rather than buying one with a compensator. You'll have to tap the block for oil return to the turbo and probably tap the head studs out a little and add a blow off valve. It'll be a fun project and probably gain 20 horses at least. Plus you'll have that turbo wind up...mmm Just be careful with sizing up your turbos... I might have a another t3 or a t2 garrett hanging around.

s***, i should have listened.

maybe wait till you have some personal experience before saying something is rediculous.
 
I'd suggest that you put the most aggressive turbo on it you can. Crank the fuel, adjust the timing to it's perfect, and run that sucker at red-line all day long.












Me, I'll be standing back.




Way back.




Well clear of the debris field.




Although the 2L is not exactly the same little problem child the 2LTII and 2LTE are, they can suffer an ill fate when you demand too much from them.

in NA the L and the 2L and the 2LTE had valve guide dropping issues. not all of them but enough that it became a concern hence my dislike for the older L series.
the 2LTE... well, we don't need to go there.
the 3L... same but not as bad as the turbo version.

in reality, there is so many other engines and makes to chose from why buy something that has known concerns that are not cheap to eliminate (IF they can be eliminated)

IMO the 2L lasts only because it doesn't have enough power to break itself. A turbo will solve that problem.
