I wanted to share with everyone the status on my quest for a cheaper and yet better turbo kit.
A little primer first: My current 1997 N/A is the second NA supra I have owned. Last year I had a 1997 black auto. The slush box coupled with the NA engine wasn't much fun so I sold it. In June I picked up my new 1997 NA - and like my last NA - vowed to make 300hp all motor.
No way.
So I started looking at turbo kits. Most of the kits in th $5,000 range (Fmax style) include turbos that are trimmed for not more than 300hp and have small additional fuel systems. The toyomoto kit was $8,000.
I decided there has to be a cheaper way. With some very good help from Dave H, I have accumulated most of the parts and knowledge to do my own turbo kit for around $3,000.
Here is what I have purchased so far and the cost including tax and shipping:
$650 T04E Turbo - .60/.69 Flows up to 550hp. (New but from private party)
$720 FMax Header (new from mmrusa.com)
$300 40mm TiAl Wastegate with .4Bar spring (new from XTech engineering)
$100 Greddy Type S BOV (used from private party)
$160 SMIC with all piping, I can use some of it (used from private party)
$97 Walbro 255ltr/hr standard pressure fuel pump (new from autoperformanceengineering.com)
So now, I have to get a custom downpipe welded and some intercooler hardpipes fabricated and the turbo oil cooler lines and fittings (probably around $250 for these) and I would be set to roll low boost on the stock fuel system and probably make about 300hp.
These are the parts to the fuel system I plan on buying to put me into the 400+ hp area and ensure proper fuel supply:
$550 Greddy Rebic IV (new from horsepowerfreaks.com)
$250 Greddy 720cc injectors (2) and mounts, grommets, harnesses (new from horsepowerfreaks.com)
$100 Boost controller (either new manual, or used electronic)
$85 Low compression head gasket (avail from some company in the back of Turbo mag)
Summarize:
300 hp (but running 330cc injectors almost full duty) = $2277
400+ hp the right way = $3626
Granted, this is all bench dragracing, and the car is up on jack stands to spring, but I am confident. Not too bad cost wise. And if you are ONLY shooting for that 300hp target, you can knock about $400 off that price by buying a T3 turbo and a 35mm wastegate.
