look at what i got coming

the point of the 3 inch downpipe is to allow the waist gate air to mix more smoothly with the exhaust coming from the primary turbo outlet, it removes the massive restriction of the stock 90 elbow, And even if your right, its still worth writing about in my oppinion, that how we learn, have fun with your 2.5 inch dp. good day

who said anything about me running a 2.5 dp? i run a 3.5dp with a 2.5wg pipe, my motor puts out 732 hp at the crank. what i was trying to say was, obviously you didn't get it, if you really want to feel a difference in power, for the money, changing the exh manifold will reap more benefits than just changing the dp. going from 2.5 to 3.0dp adds only a few more hp. changing the manifold to a header type you will feel the difference. and feeling the increase with the money spent to feel it, is what its all about. you cant just replace one part and expect a big hp increase, all parts work together, and the manifold is the biggest restriction on the stock exhaust setup. the stock vacuum actuated wg does not open up fast enough to cause that much of a restriction. if you went 3.0 from the turbo back you gain what? 10whp and you still have the main restriction problem still there. me, instead of paying over $500 for 10whp, ynot pay $250 for 20+whp? thats just not my opinion, its from over 15 years of working at toyota dealerships, building lots of toyota motors for racing, not only for myself but for customers in my shop.

well good for you. . i am running the stock manifold but its not really stock, its been ported out bigtime.same with the head, im not running the stock actuator either, and my turbo is not stock, and who said i paid 500$ ?? sorry if i seem sharp but your first post pissed me off saying its pointless. we all start somewhere. go piss in some one elses cherrios...lol

lets add this up, how much did it cost to port out the manifold? probably not much, port matching doesn't cost much. how much for the actuator? add in the 3.0 dp i'd say your more than $500. you would feel more power with the stock actuator and a header style manifold for alot less money. what good is 14psi boost when you still have the lag provided by the stock manifold? there's no need to get pissed off, this is a forum, to exchange ideas and advice. even with my years of experience, i still learn something here from time to time. espeacially from supra_girl, her intake idea is fantastic, cant wait till she gets it done and posts some pics. I guess what im trying to say is, don't believe the hp increases these parts manufacturers post about their parts. They are very biased, theyr'e trying to sell parts. my advice is from years of experience and trial and error. ive broken alot of parts trying to find what works, and if i can tell someone how to get power without wasting money on needless parts, i will. sorry i pissed you off, i didn't mean to.

im not really pissed, now! i just didnt like when you said it was not even worth mentioning it here. if me spending coin on useless items helps someone else to save then its totally worth mentioning it whether im right or wrong.. and i did all the work myself. porting and polishing and so im only into it the cost of my time. as for the dual actuator it was 100 but allows me to adjust boost in the cab without a bleeder valve. yes you do make sense i do thank you for your info. i thought about getting a header, but ive heard that they crack to easy and that the gains where minimal without a larger downpipe. so like i said i got to start somewhere... what kind and where did you get yours? are you in the www.7mpower.com top 10? you should be with that hp

My manifold is an off brand from ssautochrome.com, it holds a t/4 or larger turbo and has a 4" wg flange, ss and ported and polished. with the support tabs welded in this thing and the flange size, i never had a problem with cracking, ive used this manifold on my first 2 high hp 7m's. I've never heard of 7mpower.com, i recently started going on line to see if there are any updated parts or software for this engine, im trying for 800hp reliably for racing, its gotta live. up till now, i used my dealership and track connections for my parts and info. the first two, the cars were totalled at the track, so im building my third with a few changes. my car is not what you call street leagal, i mean, i can drive it on the street if only i know where all the cops are at that time, i race it at Mid Ohio sports track against vetts, porche's, beemers, so its not as nice looking as the ones on 7mpower. cant seem to keep them rookie drivers from hitting me. You are right about needing a larger dp with a new manifold, but, you were gonna get one anyway. the header style manifold really cuts the turbo lag bigtime, so even with 8psi, it feels like 14psi instantaniously.

ya im not going for massive power as of yet, the block is still stock so i dont want to exceed 400hp anytime soon and break it... and i want to keep this ct-26 for now and im not sure ive seen a header that uses the ct-26?

with your numbers, it sounds like you may have one of the fastest mk3's out there. certainly higher than any one at 7mpower although i have heard someone hit 800hp in vegas supra meet in a mk3 this year, but not sure who it was. thanks for the info... impressive...

the best downpipe outhere that isn t a ddp is the cooleeze downpipe huge top end of pipe it eliminates the elbow and has a great growl i m waiting to put in my new header have my external wastegate turbo and whole new ic kit on the way going from 300hp to around 450 i ll take some pics when i get all in and show u guys some power
