Jaco-Costa Rica
My name is Sergio I live in Jaco Beach Costa Rica here is aa little story on my car, soon i will post some pics.



I own a 1989 MKIII supra turbo, this car was my daily driver for 2 years, I had no problems with it.

when I bought the car it was pretty much stock. It had aa custom 3" exhoust all the way from the turbo, and a manual boost controler. Also had MKIV rims (that i hated). After a while I started to search for a little bit more power so i got a bigger FMIC from a izuzu NPR (yes that is a semi truck) and a apexi super afcII. went to the dyno, and got 213 rwHP, on the stock PSI (6psi in case u guys don't remember) after a few runs we started increasing the boost until we got to 10psi and got 240rwhp, in a search of more power we tried going to 15 psi but we ran in to the crazyest fuel cut ever made to man. so that was it for the dyno session.

Later we found out we couldn't run the TurboXS cut defender and the Super AFC toghether (at the time i couldn't figure it out) so the car just stayed the same with 11 psi and 240rwhp not bad for a complete stock 7M. it run low 14"s which was enough to smoke every honda around here, which was good enough for me.

after a couple months i gaather som money aan decided to upgrade the turbo, so I heard some guys where running a turbonetics T66 on a stock ECU with an extra fuel injector and making 420rwhp on a stok bottom end.

So I decided to get a bigger turbo, so I haad 2 options a Greddy T88 for over 2K or a friend had a rbig ass turbo that we think caame from a 18th wheeler. Belive or not we maade the freaking turbo fit in to the stock manifold, and we took the stok ECU to some guy wjo claimed could get rid of the fuel cut; and we instaalled another 440cc injector from a 3sgte. after all this was done we headed to the dyno again, we got 452rwhp after 9 pulls aand 18, psi.

3 weeks running at this PSI I heard the worst engine sound any of us would hear.......click, click, click....rod beaaring cylinder # 3.....

I decided no to rebouild but to get a fresh 7M....and then rebuild that one.

so this is my current engine
7MGTE

still don't have a power figure

ok that is a short description of what i have in the car. there is alot more, but i'm a little tired right now.

i'm shooting for low boost 450rwhp and on high boost around 800rwhp....the car is still under construction, so hopefully i can post some pics and video of the finshed product.

remember that all of this was made in Costa Rica. where it was very hard to get competent people to help me finish my project.

ok I hope you guy enjoyed.
