I want more grunt from my 3ltr 12 valve!
The 75 deserves more power (especially to drag around her heavy Italian behind).
I was shown a clean(ish) pair of heals a few weeks ago by a late model Toyota 4 Runner (4WD commercial type vehicle for those who don't know) in a 'from 80km/hr in 4th gear' race.
This disgusts me no end
!
I need options for improved performance for my Italian stallion (mule is more like it).
Despite my love of Greg's work, please don't mention his supercharger kit. It just isn't in the budget (week Aussie dollar, freight, tax, etc).
Also, I refuse to hide behind a low diff ratio! If she can't drive with decent performance and the diff ratio she has, then she is going to be sold!
Thoughts are as follows:
A new inlet manifold that incorporated longer runners to improve low rpm torque.
A twin plenum chamber/twin throttle body set up that uses a valve controlled integration port/pipe to link the 2 plenums together to (hopefully) improve higher RPM performance.
A set of long primary extractors (50cm long at least).
Some head work would be very nice! I have seen the inlet ports and was very disappointed with what I saw. I have also been hanging out for Jim K's book for the V6, hoping that it will have detailed info on porting the V6 heads, but it's release date just keeps getting put out
.
New cams would be fantastic, but some of the dollar figures I have seen for the (overrated) 164S cams is off putting. Custom cams are so few and far between.......... It's not inspiring.
A compression ratio increase is obviously a worthwhile improvement.
A programmable computer to correctly tune the set up and ditch the small, flow strangulating air flow meter.
Failing that, a low boost twin turbo set up that raids the turbos from a Skyline GTR, ebay intercooler, water injection, bigger injectors and a programmable computer.....
Engine swap..............So frustratingly tempting
.
Owning 2 Japanese performance cars tends to raise your dollar to performance ratio a lot! I'm not talking highly modified Skyline GTRs of Supra RZs but the 1's in my signature. Both of these cars slap my 75 and laugh at it. Both have performance upgrades done by yours truly. Both lots of upgrades were done with a modest budgets.
I can make most things like manifolds, but parts like camshafts are obviously beyond me, and I'm also not inclined to wreck a pair of (expensive/overpriced) heads with misdirected, over enthusiastic DIY porting.
I love the balance and uniqueness of my 75, but it's expensive engine that has such average performance just annoys me. Yes it sounds fantastic, but it's sound doesn't make it a good performer.
