Let me start by informing everyone that i am currently fixing and then upgrading my 93 JDM GT4. The issues i am facing now is that the supposed "car modification specialists" around my parts totally trash talked my 3SGTE saying that the engine would be way too weak and the transmission and differential wont be able to hold up to even 300hp. I believe in the 3SGTE thus why i am going to build her up right.

What i need your help with is:
1- Best possible break kit for price tag. between Brembo, Wilwood or mixture of porsche calipers with WRXSTI discs.
2- I'm planning to make Candy (my gt4) able to take 500hp yet run her at 300-350whp to make the parts and pieces last and not destroy them building up my car all wrong. so i will need your input on the parts i am planning on purchasing. these parts will be on my second post.
3- inform me of some east coast parts dealers because right now i am looking at Koracing out west and the shipping costs will be deadly. Maybe inform me of places who offer sweet discounts.

thanks everyone!

Colt Cams is in Canada. Call and talk to Geoff, the owner, and see what he can do for you.

Don't forget to factor in machine shop labor costs. Might as well over-bore it while your in there. No replacement for displacement, although I don't quite remember how large you can go before the block loses structural strength. Can't reach extremely high power without suffering lag. That's always gonna be a compromise. So if your turbo is capable of producing the 500 awhp your after, your gonna have to sacrifice spool time. I would wait for others to chime in on whats actually "streetable", but I would guess 300-400 and no more. I don't know much about all the different turbos, but based on a quick skim of your current turbo selection, it doesn't look capable of producing the 500awhp your after, but is more along the lines of a streetable turbo with a more moderate power increase.

Also, your car will be more fun to drive at the lower hp levels...unless all you do is drive in a straight line.

You'll need a stronger clutch and engine management too. So that's another$1500+. Then Dyno tuning is going to cost you a few hundred dollors.

I'll be the first to say that your friends are retarded and don't know shit.

If you want to be competitive with newer cars then upgrade the turbo, intercooler, and exhaust.

Just out of curiosity, are you running stock boost levels? If so then buy a boost controller and boost gauge. Turn up the pressure to 15/16lbs. That'll get you 50hp for cheap as long as the motor is healthy. Gutting the cat will get your another 10hp or so. A dowpipe is better and good for 20 hp with a 2.5in exhaust. All I'm saying is that there are cheaper and effective ways to get a lot more power from the stock motor in order to competitive. You could drop $600 on a FMIC kit, 2.5in exhaust, boost controller and boost gauge. That will get you alot more hp than you have now and keep the motor reliable for daily use. If you just want serious power and have the coin then by all means go for it.

Read this if you haven't to gain some basic knowledge of how to unlock the power of the 3sgte.

Also have a machine shop check your block before you buy any internals. If you buy everything then have it checked you may find a cylinder out of round, after a bore the stock 86mm wont work in a 86.5mm hole.

i'm not looking to hit 500awhp i'm looking to be able to run a sturdy celica with parts that could reach 500awhp but i wanna be rolling at 300-350 so i dont wreck my internals or anything. so it stays reliable ;)

hookecho---> thanks for that link i had NO idea about this and you probably saved me about 3000$ (but i wont share my savings hahaha)
Tecker184--> very good point and i shall open her up i just hope she is fine

The second you open up that block and head and start fiddling around with performance parts your reliability goes in the toilet. Its just fact. Its not a dd anymore and its not reliable. You got pay to play and then pay again to fix it WHEN it breaks. I believe stock internals have been proven to 400+ hp. If you decide to go with a performance internal build, your build estimations are at a minimum of 5 grand off when you factor in Hook's post, labor costs, all the miscellaneous parts to surround the build, as well as all the components to handle the power such as brakes and suspension.

My recommendation is stick with stock internals in the head and block, and use all that money to build a streetable beast with upgraded intake, exhaust, intercooling, turbo, fuel injection, and engine management.

well according to this link internals are fine till you wanna get in the high 300s and up. but like i said i want 300 and be reliable and so far it seems that i can be reliable and around 300rwhp with a bit of investments. nothing compared to what i was planning. the only issue i have is my celica has 200,000kms on it so its due time i open her up and clean her up. i'm planning on changing all the gaskets inside but also wondering about the gasket for the head if i should up the thickness.

The head gasket shouldn't be swapped to "up the thickness". You may choose to install a metal head gasket as they are stronger and less likely to blow.

Your internals may or may not be fine, it all depends on the tuning. I've blown engines way under 300whp but they can survive over 400whp if tuned carefully. Start with the maintenance, get everything in top shape. Only then start planning out your build. The only advice I would give is to plan for your end goal in mind. ie. don't waste your time on a piggyback ecu when your end goal dictates that you should be running a standalone.

Do you know of anyone who is very knowledgeable in tuning the car and steps to take for tuning my baby to near perfection? I must admit i am quite lost at the moment. i'm going to get myself a wilwood breakkit front and back with a tein coil over suspension with the ko racing garette t4 turbo kit because my turbo needs to be replaced its a tad broken. what i can say is my kit has been shrunk abit for modding my car. (edited look back at second post)

The way I see it is you've got 8 billion things you want to do to your car, I say set some goals with a certain time frame...like do your suspension by a certain date, wheels/tires, etc by another date, you get the idea. Otherwise you'll never get anywhere because you're overwhelmed by all the stuff you can do. It's like climbing a staircase, take one or two steps at a time instead of trying to leap the whole thing at once.

well i do have steps i just jamble them up alot haha. but here is how i see it.

1-Suspension, upped breaking system and flasher arm (pictures)
2-opening engine to clean, inspect, replace all gaskets, fix what needs to be fixed and replace used turbo with upped turbo system. (pictures)
3-start pushing for 300awhp (pictures)
4-aesthetics inside and outside (pictures)
5-Go have some crazy fun (pictures)
6-Post all this on ctech for everyone
