Guys,

on my drive, i have an FD with a blown coolant seal. In my garage, i have new rotor housings, new end plates and a rebuild kit from RA.

I want to mod it and make it quicker, but wheels and suspension come first - until im totally comfortable with the current speed of the car.

The rebuild is happening between now and 4 weeks time away.

Now my question...I CAN afford a PFC, but would really prefer not to buy one right now, i have better things to spend money on (new bushings, dent removal, respray, seats, gauges etc)

Do i port the engine now? As i say, i CAN afford a PFC, but it will be going on the credit card. How much power will i be "sacrificing" if i were not to port the engine?

Obviously, PFC and porting allows me to get rid of the air pump, emissions, full exhaust etc etc - and i hear gives me the potential for about 350whp on stock twins right? (with upgraded intercooler)

Now if i dont do the porting and the PFC now, can i just pull the engine apart at a later date and re-assemble it after porting? i suspect it will be next winter that i choose to start making the power mods (when the car comes off road, crappy english weather)

What do you guys think? its a bit of a dilema and hard for me to explain...but im sure you get my drift.

The essence of it is "do i port now and run a ported engine at stock boost, and be skint for a while so i can pay for the PFC and mapping, or do i rebuild the engine now, run it in, drive it over the summer, get some coilovers and rims and port it in the winter?"

I suspect ill do no more than 8 thousand miles this summer. Is it safe to just pull the engine apart, port it and reassemble it without replacing anything after that amount of miles?

Thanks guys...and sorry for the vauge question!

oh, and by the way, spec of the car is:

Stock engine
apexi filters
stock rad
stock IC
brand new turbo control solenoids and lines
Defi D link water and oil temp, oil pressure gauges
racing beat exhaust muffler

In the garage, i have a full stainless steel cat-less muffler-less (1 piece) unknown make exhaust (its a piece of pipe, 3 inch from downpipe to tail pipe) The car has no pre-cat as its a jap spec.

I also have a T4 turbo, exernal wastegate and BOV but no manifold for it yet.

What do you guys think?

There is no point to running a streetport IMO, unless you are running a straight exhaust. I would just go ahead and do a milder port now. You don't want to be yanking the engine just to port it later....that would be a tad "daft".

If you are going single turbo, I would definitely streetport it. The stock ecu can handle a milder streetport ok. You will need the PFC and upgraded fuel system before you can go single turbo anyway.

Port it now.

BobfisH

im not going single turbo for a while, the turbocharger was actually just an impulse buy and wont ever be fitted to the car more than likely (its an SS autochrome jobby)

I will however probably use the BOV and wastegate out of the kit. Please though guys - dont turn this into a slagging session on the Autochrome stuff.

What counts as a "milder" port then rynberg? will i see any power gains?

What sort of power can i expect running 14psi on stock twins with an open exhaust and non ported engine? As long as i can hit 350whp without a port on stock twins, i wont port it now; as i don't intend on taking the power any further until i go single turbo, at which point it will be having a total overhaul anyway (Respray, new engine, electric water pump, radiator etc etc)

So i guess what im asking is, can i hit 350whp with stock twins on a non ported engine with a PFC, open exhaust and uprated intercooler? (SMIC or similar)

What do you guys think?

BobfisH

mind you, wahts the limit of the stock fuel system? am i going to need new larger injectors to hit 350whp?

Do you guys know where i can find templates for a "mild" streetport that the stock ECU will handle ok for 6 months or so?

You can hit 350 w/ stock stuff. And you don't need a PFC to pull ALL the emissions crap and rat's nest to go non sequential.

If 350 is the goal, you can do that cheap and reliably with this car with only bolt ons. If you want anymore that is when you start upgrading everything.

BobfisH

excellent, that's what i wanted to hear. So the stock injectors are good for 350whp? (with PFC of course)

But while we are on the subject, if the stock ECU can handle a mild streetport and its going to gain me some power, what counts as a mild streetport and does anyone know where to get some templates?

BobfisH

nobody?

some people run the stock injectors that high, but they are unreliable after 12psi.

BobfisH

ok cool..but i suppose i can get around that by running larger ones and having it mapped again.

Anyone have ANY kind of links to ANY porting templates?

mazda speed or racing beat sells them I think I send the housing out for porting.
