Objective, 200hp with 4age.

[robokill]

Any engine around 200HP build by a shop will cost you over 5k easily. You will be running

- other intrake *pref ITB
- other exhaus
- head properly ported (the TRD bible has a good (maybe best) example


Example of cost

ITB adapter - $249,-
Porting head - €800,- (a price I got a couple years back)
Set of ST 20v ITB $250,- ???? (check Ebay)
Good pistons €600,- ???? (check toda)
Balanced crankshaft and rods €300,-
Refresh block €150,-
ARP connecting rod bolts €100,- ????
Set of good camshafts €450,- ( I prefer CatCams)
Standalone ECU €350 - 600,- (depending on MS or Omex in this price range)
Ignition system €200,- ????? (no clue here)
New valves plus all stuff €350,-


That is about all the items you need (correct me if I am wrong) then you need labor hours and good mechanic to build it all.

Regarding rebuild. That shouldn't be needed as you are not stressing the engine for an couple hours like in races. But you will need to swap oil, maintain it good and probably do valve clearance checks every 10K km.

Having sayd that. Mail Miguel who has a prospirit 9k RPM 200 HP 4age in his car. I believe that engine was about 10K to build excluding maintanance.
