will the engine be reliable
hello, i am new to the club , i am from portugal and i have a rx7 t 2, year 91 .
my question is will the engine be able to handle the mods i am doing without giving special atention to the rotors .
i am replacing the stock turbo with a garret gt 28,new intercoller, new fuel management system ,new and specific exaust with dual exits and new air filter,
booth from greedy.
i havent tune it yet but i believe that its better to leave it with 8000 top rpm , only to stay the most reliable as possible.
i have also changed the clucht with a reinforced one to handle the power.
thanks to everybody and ill be waiting for your comments

i havent tuned it yet because i am still putting everything together.
these mods aren´t just for racing , it´s more for driving fast on the road or to go from time to time to the track,drag racing is not the objective.
after all this is a daily driven car,and over here me and the group i am part of, we do mostly top speed challenges and some improvised races,by this i mean going from a to b in the shortest time we can.
tank you for the advises and have fun

How much power are you looking to make, and what is your intended use for the car?

Of course! I should have thought! A bigger number always means a bigger turbo!
That is heavy sarcasm. The stock turbo is a Hitachi HT-18. The GT28 is made by Garrett, and they have a totally different part numbering scheme.
There are many versions of the GT28 available, from the GT2860 which is T25 based and WAY too small to the GT2876R which has the same compressor as a GT35R. The problem is that the GT28 is a T25 based turbo, so all the hot sides are ridiculously small for a rotary.
How much power do you want to make?

i was searching for 300 to 340 hp .
because i want the car for daily use ,so if in the near future i see that the engine can handle the power and that i am not satisfied with this turbo i was planning to turn it into a twin-turbo,new injectors and fuel pump.
but for now i am keeping the 28 .
i do have one last question, is the garret gt42 a good turbo, and i mean for a single turbo engine?
once again thank you for the advises,this is my second fc but the first one i am modifiing

The GT28 will make about 180 wheel HP on a 13B. It will be a cork in the exhaust after approximately 6000 RPM, where power will drop dramatically and the turbo will overspeed and destroy itself in short order. A GT28 is useless on a 13B rotary. Do not use it.
If you want to make 300HP and stick with the GT series of turbos, the a GT3076 with a 1.06 T3 hotside is what you want. About 300HP is the maximum this turbo is going to churn out on a 13B and you will reach its limits around 7000 RPM. However it will be a very responsive turbo for the street and make nearly instant boost practically off of idle.
If you want 350HP, then you want the GT35 with the T3 1.06 hotside.
Note that both these turbos require a new exhaust manifold, downpipe, intercooler, fuel control (standalone), etc.
A GT42 is a 700HP turbo. To support it, you will need a healthy port job (bridgeport), a well built engine and all the stuff that goes along with it (standalone, fuel system, some way of getting that power to the ground, etc.).
Please listen to me when I tell you that you are doing things wrong. I'm trying to save you a lot of time and money. A GT28 is smaller then the stock turbo and of no use to you. Hell, no one even make a manifold to fit a T25 framed turbo onto a 13B.

i already have a new exhaust manifold,downpipe,intercooler and fuel control (stand alone),
but i wasn´t sure about the turbo to use .
i have seen gt 35 in several fc but i was afraid that the stock engine couldnt handle it.
in fact that was my main fear and the very little things i known about the best parts to (turbos)to make a good engine .
one last question , it is a daily use car, isin´t a gt35 to much for daily use?
thank you

A stock engine will support a GT35 without any problem. For daily use, it is a great turbo when run around the 350-375HP area.
If you have a manifold that fits a GT28, it will not fit a GT35 without modification. And vice-versa.
