I'm going to be rebuilding my motor this week. Trying to decide if I should go with an even bigger street port, or if I should half bridge it. I am going to be runing the gt 35/40 turbo again. Is this big enough to work with a bridge port? I want to be able to make 500+ rwhp at 20 psi. My main concern is reliability. It seams I can't get 10k miles out of a motor anyway. 20k miles out of a motor would be nice at this rate. I should be able to do it with my new tuner. I've also heard that bridgeported motors are hard to start and flood out easily. I don't mind loosing low end, but I want to be able to drive the car around town now and then as well as to meets and races. I'd like to hear any ideas.

dont bridge it, low end will suck, no need to do this with a turbo engine, u are not going all out power u shoudl eb able to reach yoru goal of 500whp withouht goign bridge at 20 psi.



just my 2 cents

Street port. What other mods does the car have already?

Ask Pluto how he likes his. He lives near you, no? https://www.nopistons.com/forums/pub...#>/biggrin.png https://www.nopistons.com/forums/pub...#>/biggrin.png

Just leave the street it has on it.With a bridge you will sacrifice alot of Streetability that it used to have.With proper tuning 500RWHP is still attainable.https://www.nopistons.com/forums/pub...#>/biggrin.png

where's that ecu????

I say **** it. Throw a half bridge in it. Shouldn't be too bad on the street.

Pluto is my room mate https://www.nopistons.com/forums/pub...DIR#>/cool.png You got to remember that his is pretty much a full race car, and he has another 3rd gen to drive daily. Here's my relevant mod list:



Apexi PFC with gm 3 bar

K2RD custom fuel rail with 1680cc seccondaroies

550cc primaries

SX fpr

cosmo pump(I plan to double it up and run 2 pumps in parallel)

RPM GT 35/40 turbo kit, 1.06 exhaust a/r

SR resonated midpipe

Greddy SP Catback

Greddy 2 row r-spec front mount

Mazdacomp radiator

pulleys

etc...

Sorry Ito, I was so busy packing the rest of that day that I forgot about it. If you need it tell Vosko to get it from Jehan.

Also, last dyno was 470rwhp @ 20 psi boost on c18. The results were ok, but I think the motor was previously hurt and had a stuck seal on the rear rotor. I want to break the 500 mark at the same bost level. Here's a pic of my current ports:
