Hi from Portugal.

I have a doubt that probably you guys can answer.

I've blow out for the 2nd time my 4jg2T (due to non original spares, and other reasons )
but here in Portugal, usually they ask for a complete motor (without accessories) more than 1200€.
but now appear what can be a god business for me, a complete 4ja1T for 500/600€

It will be put a fuel pump with 12/13 piston and a hybrid 23/59 turbo with original shell (it was already installed in my 3.1)

I know that 4ja1t is low in power (76hp), but if with a VP44 they can get 100hp, with a modified mechanical pump, should have more.
and I also know that is less 600cc, but, when I see putting 200+hp in a Nissan TD27 without problem, we see that CC is not always important.

What I need is help about pros and cons about 4ja1T against 4jg2T.

thank you guys

4ja1 is direct injection This means you cant use your current pump without further mods but it is better able to handle power mods. Also you get easier starting etc . Should have no trouble fitting and the power loss will not be noticable. The older 4jb1t can be modified to more power than a 4jg2 can safely handle
