Important Question STock Or streetport ??
hi iam maurice better known as maus
im from holland
im currently driving a 94 type r fd
silver ( soon orange )
but im having a problem
my engine needs a rebuild
my current setup
knightsports ecu
knightsport high flow turbo´s
hks radiator
hks exhaust
further the car is almost stock setup
nowmy question is what should i do
in holland the knowledge about streetporting is verry sad
my garage offered me a full rebuild stock( not ported)
with 3 mm seals
but what can i expect if i want more power whats possible with the stock engine
or should i do a streetport and what can i expect then
by example
im rebuilding the engine without porting it
then later on i put an fmic on and a a single turbo
what can i expect in power
and are there any people who are currently driving a non ported engine and what are their horsepowers

Your main problem (or limitation) is going to be your ECU. Depending on what it's programmed for (of its just a rechipped ECU), it may or may not have a problem with a streetported engine.
To be able to really take advantage of a ported engine, you really need a programmable ECU and a tune just for your setup. You can gain some power with mild streetports which don't require ECU changes, but that doesn't sound like what you are after. Either way, with a single turbo, you'll need a programmable ECU and tuning at that point.
There are people who have taken the stock ports with single turbos well beyond 400rwhp. Check the Single Turbo section on this forum as I believe this was just recently discussed.

you should get the street port. your engine is going to breathe alot better with porting. i would get 2mm apex seals becuase i heard the 3mm apex seals have increased friction and rob power on street cars. correct me if im wrong. atkins racing makes some good aftermarket 2mm apex seals that hold alot of power. regardless ur gonna need a stand alone ECU. your power output is gonna depend on how well tuned ur car is and how big the turbo is.

Hey Sgtblue. give Jeff a call ay Rotarypower in California (310-516-9959) he dose a mild street port that can pass smog and retain the stock ECU. when my motor blows this is what I am going with. Jeff is a great guy to deal with so he can answer all your questions.

Mahjik is the only voice of knowledge on this thread....
Porting a motor is a difficult path to take if you don't have good access to a proven reliable rotay tuner. I don't think you can safely run a ported, turbo motor on a stock ECU on the FD. The porting changes the timing needs beyond the stock ECUs programming.
Might also want to check the European section on this forum for other FD and rotary owners near you and in the UK.
CrispyRX7 and cewrx7(r1?) use Aspec's GT35R turbo on stock ports and seem to be very pleased.
