Re: Good new turbo to replace CT26 on 3SGTE

actually your right about two things i should perhaps have written group N assumed (god forbid) that the group A badge on the centre console meant exactly that( being very technical).

but toyota did develop st 205 for rally application as to when or how it was used in competetion(or if at all) i do not claim to know

but based on the fact that i dont actually know or care i accept you are probaly correct.

i was merley trying to pont out the BREEDING behind this model

second of all i am aware of a person that HAS done this conversion onto an st185 i cant swear by it but im sure he used a factory manifold .again i assumed the 165 was the same as 185

happy to put shit on people when they are wrong equally happy to admit that i am wrong as well

BUT CAN YOU?????????????

seems to me you just wanted to join the "ya couldnt POSSIBLY get that much power bandwagon"

NOW TO THE STUFF THAT I HAVE ALREADY DONE AND KNOW WORKS

as far as the dump pipe mod ..well that was easy remove the cat and fit a high flow after market further down the system .this gave a similar result to that of which you have already described . in fact this car made 220 h.p @ whels at 16 psi and this was noted in h.p comp at the toyota nationals .

having said that a custom dump pipe IS in the making .BUT gains are only expected to be minor .the main reason for changing the design is i feel the new design will remove more underbonnet heat as we are also having it ceramic coated .as far as increasing flow that is highly unlikley

using the factory 440 cc injectors and the standard manifold at 294 rwhp duty cycle was 90 %

so we decide to extrude hone the intake manifold .

the much smoother manifold allowed for less manifold wall quenching and faster air fuel flow .

cylinder n.o 3 was some 30% more restrictive than all others

at 320 H.p duty cycle was reduced to 87 %.

fuel rail pressure has since been increased but as i did not personally do the tune im not exaxtly sure of the current duty cycle.however in the tuners words .it should be safe for another 20 h.p and thats about all

as far as the turbo mods go the only component that was SLIGHTLY modified was the ceramic wheel it was replaced with a steel item of SIMILAR spec

the real gains are from the extrusion honing the exhaust housing was so heavily ported that its now 30% larger than the original.the exhaust manifold was also ported and ceramic coated .The reason the turbo is so effecient is the gains from porting the compressor housing and intake manifold

The ST205 WRC turbo is exactly the same and a normal ST205 turbo.

i asssume you meant to say the same as a normal st205 turbo
(NOT PICKING ON YOUR TYPO MY TYPING SUCKS)

perhaps you should check the link below

this clearly states quite a big differnce including the turbo .and the fact that the wrc IS A full second faster 0-100 IN STANDARD FORM

http://www.alltrac.net/specs/comparison.htm

should i mention the anti-lag(standard in wrc) or the injector sprays also standard

Maybe you should have a look at a real ST205 before you go around spreading your 'expertise'

perhaps you should take your own advice

the vehicle in question ...NOTE MY CRESSIDA IN FRONT

look carefully under the gt4 badge it says GROUP A RALLYE

it also has an id plate on the console with a build no ## of i think 77 in AUST

the ST205 has 239hp at the flywheel stock,

again quoting the above link to alltrac an st205 WRC has 255h.p (st205 has 242) so thats about 173 h.p @ wheels .well we actaully got a figure of 181 so we are close to the claimed mark

we added 3 inch exhaust and cat mod ,cold air induction and 16 psi boost power figure rose to 225 h.p @ wheels as i said this has been varified

so the actual gain from turbo mods has only been 100 h.p @ wheels .But this is still a substantial gain considering the cost

i still have a few pics on the role of film with the before and after pics of the turbo .so when i finish it i'll get it developed and show the results

for those of you that are actualy interested in this mod

Finally if there is any doubt what so ever this vehicle IS competing in 1/8th mile drag racing at THE toyota nationals this year .

and previously won the go-to-whoa by a substantial amount

i have a 4.5 sec 0-100 car and i am SCARED ... VERY scared of this vehicle

you are more than welcome to take it on

it WILL have fitted at the time a dyno plus for 0-100 and 1/8 th mile and h.p readings
