morgey Posted September 8, 2013 Share Posted September 8, 2013 (edited) Headwork, cams, ecu, exhaust, mani, flywheel, intake parts, possibly pistons.Not a hugely tunable n/a engine without a lot of work tbh Edited September 8, 2013 by morgey Quote Link to post Share on other sites
Xpect Posted September 10, 2013 Share Posted September 10, 2013 Forged Pistons, same Compression, raise the Rev-Limit to around 12000 Quote Link to post Share on other sites
morgey Posted September 10, 2013 Share Posted September 10, 2013 Forged Pistons, same Compression, raise the Rev-Limit to around 12000You wouldnt need that for 150whp,I make 131whp and mines gotHks 4-1 mani3" sports cat2.5" cat backFidanza F/w75mm trumpets Itg sock filter.Auto ecuWith a set of good cams, .6mm trd head gasket, and a ecu and map i wouldnt be far off 150whpBut if raising the rev limit, balanced silvertop or late 16v rods and a set of arp rod bolts would be strongly advisable Quote Link to post Share on other sites
Xpect Posted September 10, 2013 Share Posted September 10, 2013 With raising the Rev limit together with supporting mods like 4-2-1 Mani, ITB's, 200 or 100cell cat, cold air intake to the ITB's, a bit bigger exhaust diameter, bigger injectors, better fuel pump, wilder cams and so on you would get way more than 150whp.
