haha, 70k can buy RX7 liao ler
True this maximum modification to do it lo and let professional to do it lo(from what i know if you ferrari F360 and you let NOVITEC from overseas to tuned and upgrade you ferrari for another 100HP the cost is about RM250,000). Rx7 if u want to buy also better no buy lo it rotor then ti brake down at every 60K mileage.
For best buy some US like cp piston(can boost 2 bar), eagle rod(boleh tahan 600HP). to increase you car performance i think if u can order direct from us is very cheap for cp piston about RM 1925(without delivery fees of course) but in malaysia they sell for RM2900, if eagle rod it is cheap also RM 1155(without delivery fees of course). CP piston can customised whatever piston u want but only the money is the main problem only.
If u have extra money put sleeve in to your engine block example darton sleeve, it cost about AUD$550. If install this, confirm u block can withstand 55psi for sure.
engine internal part have been strengthen you can put some big turbo like gt3540 and gt3037s for 2000cc engine if u have 3000cc u can put to4Z ot t51R kai and some good ecu like motec or haltech but cheapest still is F CON V pro to squeeze the maximum power of your engine.
Port polish increase you valve by 1+mm in order increase you combustion camber and good air flow, put high cam like 272 degree and open pod air filter, to increase the rpm range and some power also at least 30HP gain(crank hp). if can put another okada plasma direct coil to u.
But in order to cope with that to prevent the clutch slip u must upgrade some decent clutch like ogura twin plate or os or exedy about RM4500+-
but after increase for so many hp u want stopping for sure for upgrade cheaper kit is VTTR rm 5K+-
but u want ultimate stopping power choose ap racing but prepare to pay 10k above.
For handling
For suspension i recon tein, not HKS hipermax because it tend to have noisy coilover after use for a long time.
if want to further minimize body roll and direct feel of road condition change your bush to pu bush such as super pro, whiteline and powerflex.
Is this help u? :)
i think u downloaded 2 much porn
