Hi
I'm new to the forum and am looking for some thoughts on what an hilux R22(not efi) engine can be be tuned to produce with
High compression pistons
Webber carb
Mildly lumpy cam
Full rebuild and head tweaking
Extractors
Tuned for 98 oct fuel

If its done well....what % power increase can u expect?

Can a nasty cop defect the above mods?

I understand if you are prepared to accept a rough but reliable idle
you can get more power. What's it like driving a ute with a lumpy idle, if u are doing a lot of city driving.; annoying or a source of joy??? The tuner says it wont stall.

Is the tune pretty stable or does it need regular adjustment?

What sort of increase in fuel consumption might be expected?

Can you keep it reasonably quiet...exhaust wise, for example if stopped by a cop for random breath test.
Or does optimum power equal maximum noise.

I'm looking a spending quite a bit on the engine rebuild and upgrade , about $11-12k
And would really appreciate some wisdom from more experienced members.
I'm also getting lsd and decent 16 × 7 wheels. RN90R xtra cab rebuild project.
