4g93t halfcut is expensive last i bought 10k+... replace critical parts, then suspension, wheels, rubbers. Couple of thai defi gauges. Depo AFR.
Braided brake lines. Superpro bushes _ thanks @Izso .Total took me 3yrs+. Current engine is stock.
35k maybe or cukup makan if you include engine mods.
I not even start fiddling with "engine" mods yet. Hahaha...anyway i daily my wira to everywhere.
Wow! my time was much cheaper but then money value was bigger those days, however I think affordable as my 4G63T was RM1.5k only, all in under RM10k as workmanship also cheaper those days....lol

I really appreciate all the advise given. To get a new car was never in my thought but probably a used Nissan Silvia S15 or 14 or a Mit Evo9.

Having a supercharger 4g18 sounds interesting but my doubts is not about the supercharger but the engine 4g18. Can the engine really last long. I have a very bad driving attitude, what I mean is I always drive on high rev, been practicing this for the past 7 to 8 years, I'm glad the 4g18 is still good thats probably because I always give a good engine maintenance for the 4g18. I would probably sell the engine but not the car.

Getting a 4g93t inside the Waja is a great idea to me. I will not worry about the petrol because if it's going to be done with 4g93T so the car will be used only for weekend drive. It took me almost 5 years to understand the 4g18 engine n today I can drive my waja so crazily even knowing my tyres are all BOTAK. hehe actually only the front wheel tyres back still ok. Moving on, I dont know how long am I going to take to study and drive the 4G93t at top speed and still being calm and cool.

If I would choose the 4g93t, is 35k enough for a complete 4G93T Waja.
AMR500 supercharger is a very small supercharger, max boost you can hope for is 0.6 bar, generally it requires less maintenance, its like having a second engine, it has a dipstick for you to check its oil level so you don't dry out the roots inside the supercharger. Best thing about supercharger is fully mechanical driven and it depends on your engine RPM to produce boost consecutively. Reliability wise, it doesn't produce much heat, pretty good for your "abuse", just make sure your supercharger pulley and belt is always in good condition. Since its small, you can fit into any engine bay easily, things you need:

1.) AMR supercharger
2.) Custom bracket to mount the supercharger
3.) Electric power steering pump (if the stock hydrolic pump is in the way to mount the supercharger)
4.) Custom intake piping
5.) Bypass Valve (not the same as blow off valve as you are rerouting the excess pressure back into intake)
6.) Intercooler (may need or don't need depends on your desire)
7.) higher CC fuel injectors
8.) Better spark plugs
9.) Better ignition cables
10.) Better ignition distributors
11.) Piggy back ecu to optimize everything.
Optional : Custom pulley to increase boost.

Noticed i didn't mention exhaust system ? Supercharged engine relies on the ENGINE itself, rather than exhaust driven turbo.

Downside is, supercharger will have parasitic effect to your engine, there's an old folk saying in the past, for every 100hp you made with turbo, you lost 10hp, for every 100hp you made with supercharger, you lost 30hp.

PICK YOUR POISON !

35K is a good budget. Can get everything done for that... but if you've never had oil/water temp & pressure issues, when you start modding that's where the fun starts.

Constantly whacking a modded car it won't last as long if you don't know how to prolong the lifespan of it.The 18 if built, has proper cooling and good oil is used it'll last for a while.

On the opposite end, if you whack the living shit out of it 24/7 without monitoring temps it'll end pretty badly. This goes for the 93 as well.

I would highly suggest the intercooler. The supercharger's IAT is pretty damn hot if not intercooled haha.

EPS conversion also you'll need a standalone for the PWM to maintain the pressure.
