advice for 86' SVO
i have a 1986 SVO
roller cam
ARP head studs
35lb injectors
adj. fuel pressure reg
65mm throttle body
adjustable cam pulley
190lph fuel pump
msd coil
RAM HD clutch
17" cobra R's
im wondering what turbo would be best for an upgrade. i want to keep streetable since i do alot of city driving; but also want to use the brute force the 2.3 can handle. i dont know anything about external waste gates and would like to keep the price some what sane. should i buy a rebuildable t3 and sent it off to CMR and have it turned into a super 60 t3? im not interested in the bigger is better thoery. this is my daily driver and want to have fun with it while i drive it daily

Unless you are upgrading to a front mount intercooler you'll need to keep your stock compressor housing. This will kinda limit your choices for upgraded compressors. Get with Rob at www.extremeturboshop.com and he can tell you what the biggest wheel you can fit in a stock housing is and what HP it will make.

OK, so that opens up your choices then. There are a couple of options if you want to stay garrett. You can do a T4/T3 hybrid using either the 50 or 57 trim compressor. Many people run those. Another option that is becoming more popular is the Holset HX30 from a Dodge diesel pickup. They are HUGE, but many people say the spool as fast or faster than a T4/T3 and are much better at higher boost levels. The holset also bolts to a T3 turbine flange so it will work with your stock exhaust manifold.

How about some pictures of the SVO? Seems more and more SVO owners are coming out from whichever rock they live under. Still miss mine...even though it treated me like shit.

more and more SVO owners? only a hand full in tampa. maybe 7-10 on a good day. if someone pops up with an SVO more than likely one of the other owners sold out. i just put the chrome 17" cobra R's on it and dam did it change the total appearance of the car.

Sounds like a great start to me. I think I mentioned that I got the Holset off ebay...$161 was the winning bid. Man, I'm excited about that! It's an Hy35, which was used on the automatics, I think. They supposedly have a smaller turbine side, so it should spin up faster than the HX35. Honestly, I have no idea what I'm in for! I'm thinking about going to the junkyard for a spare engine even before I get started!
FWIW- I've heard mixed reviews about the headstuds and the 65mm TB. What's your opinion on those, Dave? I know I've used the same set of 12-point bolts about 4 times now, and I've never had a problem, a blown headgasket or anything like that. This is with a non-decked rebuild junkyard head, and there's been a LOT of detonation along the way at times, too.
My feelings on the 2.3 are that the biggest shortcomings are the stock computer and then later, the stock head. I think there's a few guys out there with very mildly modified heads and standalones with big turbos making big power. Good heads are $$$ for the 2.3, and working an iron one sucks because it's just a matter of time till it cracks. They ALL do it.
