what kind of power u think id put down on 12 psi with just the turbo kit and ptuning exhaust with the auto?

 

With immaculate tuning with some detonation, maybe 300 whp.

Remember the car runs its hardest just before detenation... Coincidentally most cars feel like theyre running their fastest just before the insides of the motor begin to melt.

 

300 whp thats it jeez i got my work cut out for me... manuals are puttin those numbers down with 9 psi..

 

Yeah, but perhaps with a more efficient torque convertor, your numbers may be a lil better... I really have no clue how much lower that may be as I only built one auto tc b4.

 

BTW if you are trying to get every once of power out... I would go with an exhaust cutout b4 doin injection.

 

true. i guess time will tell. ima get it dyno'd with just the new tranny and then ill build it based around those numbers.

 

WTF? So you're telling him if he builds his head first he'll make more power with his turbo car then if he built the bottom and turned the boost up?

Raising the compression from stock on a boosted tC probably would not be too good of an idea. Yeah I'm sure it could be done but it's not an SI.

Some of the things you have said has been good but that last part of that post was just crazy IMO and I'm sure many others who have built a tC would think the same.

 

^ i was thinking the same thing.

doing internals and raising boost sounds more promising.

 

and japtrix is CLOSED today so i cant get my quote. dangit.

anyone else have some guesses to how much a shop would charge to drop the motor out. put internals in + balance and put motor back?

 

I said build the head because of his power goals... If the stock rods can hold 400 hp and his goal is 350... Building the bottom end will only make the car safer not make more power... Building the head will allow the car to rev highier safer and prevent valve float... He can also benefit by adding some higher flowing valves... Not saying that buildin the bottom end is bad at all... You can make more by throwing as much boost into the motor as possible or you can make the engine run more efficiently meaning each stroke will draw more air in and push more air out...

 

[quote="etsnet"]Also we have built motors with 10.0-1 compression pistons on turbo applications and worked very well up to 20 psi on race gas... As a matter of fact JE or Mahle have a production 10.0-1 piston for the 2AZ... Im not saying he should raise the compression, as this will cause him to have some more tuning issues as the weather changes. Im just stating what will net the biggest horsepower gains... Building bottom does not directly equal more hp... It gives you the ability to achieve more horse power by other means... Building the head will make more hp without making changes to anyother parts or raising the boost.... Its that simple

 

CP pistons 570
Manley rods 760
supertech valve train 800
valve seals 30
gasket set 70
cometic head gasket 75
arp head studs 110
clevite bearing set 100
machine work for head and block including notching the block for rod clearance 875
motor removal and installation 1000

Total 4390

 

lets say i already have my cp pistons, k1 rods, arp haed studs and bearings and cometic head gasket. im just trying to get an estimate for a shop to remove the motor, install, balance and put it back in.

 

should be around 2000 with all the fluids, plugs, oil filter, and engine gasket set.

 

Actually less since the head wont be touched... So around 1600

 

true. arite i just purchased my CP 9.0:1 pistons, K1 Rods, Clevite bearings, ARP head studs and Cometic head gasket.

waiting on the stupid tranny to get back.

 

recently i started thinking of building the motor depending on how much it will cost, since i wont be driving my car much for the next at least 6-8 month ( military training ) i'm thinking of dropping the car off at Dezod depending on how much they will charge to build the motor. lets say drop off late winter or something and pick april-may if they are done.. wonder if $5K will be enough including Port N Polish head. then u can just turn up the boost on S1 kit to like 15 psi and possibly be at arounf 400WHP..
not the question is, with that power LSD is like a must, and axels, are there any shops that rebuild our axels ? i did see something online but the price was like 2K for each or something..

 

our axels are good for like 500 hp or something even higher. i believe

 

Stock rods hold 400hp = NO WAY JOSE!


The higher comp pistons for the tC is usually for an NA build. Although I would like like to see someone build with 11.0:1 in the tC and boost on like 10psi and see what happens.

 

That is incorrect. I believe it's 300 and even then you have to be careful but if you don't launch hard you'll be fine.

BTW, K1 rods will not need notching.
