There she blows!!

Motor blew this morning at 6:30 @ 120 mph going to work. Rear rotor threw an apex seal. I think she leaned out, probably due to a clogged fuel filter or possibly an injector problem. The plugs were a lightish tan color. NA's run rich, so I'm guessing the detonation killed it. Hopefully the housings are still usable.

Gonna start the rebuild at the end of the month. Any ideas what kind of porting I should do? I was thinking about porting the throttle body, port matching the UIM and LIM, but I don't know what kind of intake/exhaust porting I should do. Throw some ideas out. NA driveline probably won't handle too much power, but I'd love to dish it out anyway. Clutch has about 5k on it.

Mods in sig. Probably gonna go with an S-AFC II for a piggyback, as well. Turbo is just out of the budget right now, so I'd like to stay NA and and be able to whoop on most **** on the street. A bridgeport is out of the question, but I'd like to get ~200-210 WHP, with as big a port as possible, while still retaining driveability and not having the motor blow 30-50k down the road. Is it possible?

For intake porting:
Port match the intake manifolds and port the TB.

For engine intake porting:
Get a Kahren Stage 1 templates or a Mazdatrix. Both are efficient and proven.

FOr engine exhaust porting:
Remove the diffusers, go big, possibly get a Kahren template. You cant go really wrong there.

With the Kahren or the Mazdatrix port you'll need that SAFC and 550CC secondaries, I also recommend a new fuel pump.

That should put you in respectable numbers.

Thanks, Jason.

I have a bad feeling the rear housing is gonna be fucked, cause when I pulled the plugs to check for compression there was a terrible scraping noise, which I'm assuming was the apex seal spinning around in there.

200-210WHP on an NA is going to be more work and money than building an equivalent turbo motor with less milegage\reliability. I think...

How come? A nice big port job, injectors, fuel pump (???), fuel controller and if funds permit MAYBE an ignition system (Jacobs, MSD?). I don't think that will compare to having to get a turbo motor, possibly new turbo, wastegate(??), 3" exhaust (to maximize power) all time to wire new sensors and harnesses in and the above mentioned NA parts. Not to mention a stronger drivetrain, cause I'll want to up the boost.

Not trying to bite your head off or anything like that. Just trying to put things in perspective. If you see it differently, I'd definitely be interested in hearing it. I'd love to go turbo, to be completely honest.

Thanks for the opinion, too. And if there are any more ideas or advice out there I'm open.

dude get a jdm turbo II engine and do the swap,then you will have your reliable 200-210 RWHP..

yeah they are $1,200-$1,500 but thats what you gonna spend rebuilding an n/a engine that you will need a turbo or nitros to make it fast......

200 RWHP wont feel fast after you drive the car a month or 2..trust me i had a 89 turbo II that ran 14.2 and after a while it didnt feel fast at all...

thats my opinion.......

But then what about the drivetrain? My transmission has almost 60k on it, and that's the weak link in the car. I feel like, as long as driven properly (no slammed gears, powershifting, clutch dumps, etc) the rear end should hold up fine. Since it is a base, it is 4-lug, as well.

But it sounds like it would be a nice idea... lol. Have any links or anything?

Lol, yea... that would be a little crazy, and too much $$$. Probably wouldn't work either.

if your not planing to drag race,or launch it at like 7,000 rpm you shouldnt worry about braking anything on the drive train.

i have a turbo II engine done with block off plates and all,it has 100psi on each rotor, i am thinking of getting an FD engine so it might be for sale.i have the ecu,wire harnes and censors everything yo need for the swap..if your interested let me know

the only thing i didnt do to this engine is port the wastegate because i was going with a bigger turbo...
