i recently bought "another" fc, i bought this car because i know its history and got an excellent deal!! its an 88 s4 block rebuilt with a nice street port! i bought it with 400miles on the engine, ive now finally broken it in but there is just one problem..... the person who owned the car before me was doin the engine build on a budget... (luckily my friend is the mechanic who built the motor, not the cheap skate who owned the car.. anyway.... Mr cheapo bought himself a $200 ebay t3/t4 hybrid kit with manifold... the a/r on the hotside of the piece of **** is only .43 with a standard to4e cold... as you may Assume the p.o.s. bottle necks so bad ive blown 2 holes in the p.o.s. manifold and rewelded it twice now... so what im getting at is Im going to buy a turbonectics turbo for it, do i go t3/t4 hybrid again?? with a .63 ar hotside... or is this just still to small to match up with my street port... i dont want to wait around all day for boost either, so im thinking a t4 with a 60-1 cold side with a .84 on the hot!!? ive heard this size is not overly laggy at all.. unfrtuneatly ive never been in a t4 equiped fc before.. i own 2..1 wth stock a Turbo, the other with the ebay piece of ****..
also if i do the "small" t4, can i get by with a stock ecu, 1000cc secondaries and an s-afc?? ive used an safc quite a bit with friends on their hondas, they seem to work pretty good... i dont have any tuning expierience aside from safc tuning with a wideband so the idea of a standalone frightens me, and im just learning about the r-tek ecu mods.. do i run rtek and sAFC? or just one or the other!?? basically im trying to eliminate the **** baby turbo and would like to ugrade above stock at the same time witout creating a monster supporting mods list at the same time.. help me please guys!! it seems no one wants to help me buy a turbo!!

 

car already has fd fuel pump and rb oil pressure rgulator

 

the GT35 comes with a T3 exhaust housing, and .63 seems fine, BUT you NEED the bigger T3 turbine wheel, i'm not sure what the GT35 uses, but you need that size wheel, OR the T4 p trim wheel.

the T4 60-1 with a P trim exhaust wheel in a .84 housing is a good choice too. last one i drove would hit 10psi by around 3000rpm, plenty fast enough on the street. that car was running a totally stock fuel system with an Fcon too, so bigger injectors are a great idea

 

sorry im so clueless, lol when you say P trim, im assuming thats the size of the wheel in the hot side.. on the "custom turbo sizing at turbonetis gives me 4 different sizes to choose from on turbine wheels for the "t3 housing.. 49mm 54mm 57mm and 62mm.. which one of these is "p" trim??!!! also, specs i can find on the gt35 show it to be a 70 series cold side with 3 options of hot side .63 .83 a 1.06.. i cant find anything on the turbine wheel size!! any help would be huge!!!
just my newb ness showin again here but isnt a 70 series cold side moving a lot of air to be fitted up to a t3 with a .63?? im used to most t3/t4 hyrbids running to4e/b compressor..
im glad to hear someone you ^ know ran a 60-1 t4 wit .84 ar on the stock fuel system!!! im ready to BUY as soon as i know what p trim is lmao

 

A .63 is too small for a rotary, .84 is the smallest one should ever run. There is only about 300rpms difference in lag between each step in turbine a/r( .84 to 1.0 for example). Call us on our toll free number for the right size turbo. We carry all brands.

 

i will definatley call you tommorow! thanks

 

Same here, my car hits 9psi (wastegate spring) by 3000rpm. Thats a T4 60-1, .84, on a stock ports 13B, 4 in dp/mp, RB REV catback.

Power delivery is VERY smooth, makes you think that the car is slow

 

knonfs are you running stock ecu and fuel system??

 

i can get a 60-1 .81 ball bearing for a good price right now, you guys think the difference between .81 and .84 would be much difference??? sounds so close in size to me

 

No, those numbers wereo n a haltech e6K, 720cc primary, 1600cc injectors, and a bosch 034 fuel pump.
