ok guys, ive been down the turbo road a few times and have loved but.. if i do it again i will most likely have to get custom pistions/ rods sense i cannot find some 4agze pistons. either way i am collecting parts to get her on the road again for this summer. so far ive got some more gauges on the way, new ACT clutch to be installed... i am waiting to see which pressure plate i want, i'll probably go for the 275tq one just to be safe. either route i go with my motor will be getting a port and polish job... rear drum to disc is also on my list to be done but sense i have had many problems with the turbo i am now looking into N20 (i guess i going backwards as some may see this) but, has anyone here ran nitrous on there 1.8 7afe? im looking for all details like:

what brand nitrous kit?
dry wet or DP (direct port)?
what size shot?
upgraded clutch?
any problems experienced?
anything else worth noting...

thanks for your opinions and input in advance.

that damn fuel pump.

anyway, my engine was in perfect condition other than the melted piston

all the other cylinders were OVER 200psi compression even at 16k NA miles i put on the car and another 6k at 8psi

i got to look at all the internals of the engine and everything looked good, if only the fuel pump hadnt have gone out.

but sadly, 6k miles isnt enough, thats like 2oil changes... not busting balls, cause ive blown my fair share of 7a's here.. my local toyota calls me for 7a parts now, im not joking about that either. im thinking i am keeping the boost, downing grading my turbo, and my boost addiction, upgrade the clutch thou. i have all the **** that i shouldnt blow it up again. i just got boost horny and ran 10psi for a few weeks.(ask the guys at the king of prussia meet, i gave everone a ride in car...) the dyno tune was good but the pistions gave up i believe due to the piston rings... they over heated and touched ends, cause the piston to crack/ deform.
