Ramrod hit the nail on the head , its really going to come down to which one was better maintained over its life , squirters are nice to have but not necessary at all especially for the power levels you wouod want but they are a nice thing to have if you can .
The first thing I do with any turbo car is install a Wideband gauge so I can watch AFRs they are cheap but worth their weight in gold.
Also if you are substantially turning it up maybe consider an electric boost controller like the GFB ge force 3 .
I run that and it has a lean cut feature which is absolutely brilliant and has saved me a motor .
I was racing a guy at 24psi my eyes were glued to the road not the gauges , something happened and it leaned out but the geforce caught it and dropped boost to wastegate pressure I felt it go from 24psi to 12psi it was like hitting a wall, I looked down and seen my temp gauge rising I switched the car off and coasted off to the side .
Head gasket blown but no other damage and it didn't get a chance to get hot .
If I didn't have the lean cut feature I wouldn't have backed off and would've ended up cooking the motor .
$300 very well spent in my opinion .
Just something to consider , LH2.4 is capable of quite alot but it is old and slow you want to keep an eye on things just in case .
