some general questions on the car i will buy

[ditn]

@slowboy2
No im sure its a 4AGE because of how it looks and
you would need to be isanely lucky to get a 3sge trough the belgium inspection,its impossible
I found a picture of how it looks

4AGE look+toyota 1600 in black and twin cam black & 16 valve red+TVIS system,cant be anything else than a bigport redtop.
Im still not sure why he has done it,im hoping internal tuning

@Bean Bandit
Yes 160 hp is my aim,if i read correctly anything above will start to get expensive.
Since the engine is young it might indeed be the right choice to stick with it like you say @ 160hp
on further reading i start with 9.4:1 compression on the bigport engine
I was indeed thinking of a 0.8 mm TRD Metal Head Gasket.
So it might be best to replace the rodbolts then?(arp are the best choice then i think?)

The more i think about it the more i go towards the 272 cams,
for me i think this will be the perfect range since im not going above 160 hp anyway.above 272 or 280 will probably be alot of stress for not that much power gain?
or not?

some cams i have found so far
HKS
Duration: 272 / Lift: 8.35mm, Intake / Exhaust
Duration: 288 / Lift: 8.30mm, Intake / Exhaust
Still doable lift?

Not sure yet on throttle bodies,not allowed in belgium
maybe if i can hide them like in the silvertop manifold

--------------------------------------------------------------
Starting to research also for a rollcage/sport seats.
I tought i found a brand close by in safety devices but there cages dont look to safe.I might go to someone locally who makes them.
Whats really annoying is that only bolt in cages are allowed here in belgium.

About the seats,is it best to reuse the standard rail from seats or weld in 2 bars and put them on there?

so much questions,
but i rather have everything planned before than surprises after
