I wanted to wait before posting my build Q's, but got a warning that I said i could be dropped for not posting.
I picked up my 1st MkIII the first of May, it is an '87 Targa 5-spd w/ a sun bearing. My plans are either to simply rebuild the engine resto the interior, fender dent and cracked windshield and sell it, or do a power rebuild and keep the car as another toy.
If I decide to keep the car(not sure until I get the engine out and torn down). I would like to do a power build in the area of 450 rwhp. However since the car will be used for weekend drives through the mountain and river canyons in my area, I am not looking at simply bolting on a larger turbo for higher end gains. With the car as heavy as it is I am thinking I would want my gains to be on the low end, sub 3000rpms. I have found with my Toyota trucks mods to increase low end power have been the most beneficial in terms of performance, like the Supra the trucks are also heavy.
Since my only experience with the Supra was from test driving TT MKIV's back in the '90's(when I was considering buying one), I have no reference point for the MKIII single turbo. What is the performance like taking off from a stop, or throttling out of corners? Is there a lot of turbo lag w/the stock turbo?
Some more Q's:
Is it possible to run dual turbo's on a 7mgte?
Is it possible to piggy back a low end turbo with the stock turbo?
Will the stock injectors and fuel pump meet the fuel demands of 450rwhp, if not how much Hp will they support?
I had considered boring the block out to .040. is this too much, should I even bother with enlarging the cyls?
I have been customizing/restoring Toyota 4x's and 2x's for a long time now, and in the beginning I spent a money on items that really wasn't needed and would like to avoid that with this rebuild.
I would like the members input here on how they would go about rebuilding to gain the hp I am looking for and the use I plan for the car. Or would I be better served simply restoring the '87, sell it, and look for a TT MKIII?
