I am sad https://www.nopistons.com/forums/pub...O_DIR#>/11.gif I have bought the turbo so will have to live with it for atleast a month...before i can order a new one which will take another month to be delivered .. No i am very very Sad https://www.nopistons.com/forums/pub...O_DIR#>/11.gif https://www.nopistons.com/forums/pub...O_DIR#>/11.gif https://www.nopistons.com/forums/pub...O_DIR#>/11.gif Also what turbos would fit on this manifold? So that i only have to get a new turbo.. Also how much would this turbo produce at 10psi of boost.. One last question can i run this turbo at 10-12 psi without upgrading my secondary injectors.. i am using stock injectors.. Just have a Power fc... Oh i know this is the O trim but how do i check if the a/r is .70 or .84? I have attached a picture of the exhuast side of the turbo in an earlier post... i know the picture is blurred but can anyone make out the A/R? Thanks alot |
The wastegate on my T3/T4 has a stock boost setting of 3 1/2 psi, which is good, because I don't have a boost controller. My question is, what my current set-up, how much boost can I run safely?
I've heard SO many RX-7 owners diss electric fans, and mine is single at that. The temp gauge reads at about 1/3 the entire time. The other problem is, my 5th gear synchro is bad so I'm cruisin at like 3,500rpm in 4th gear just trying to keep up with traffic, i don't want to be pushing so much boost that my car's going to over-heat or anything. My injectors I found out are stock S4 Turbo II injectors, but they have been blue-printed and balanced which makes them work more efficiently and flow fuel better. I dunno. o_O Help? |

In my opinion the O trim AR.70 exhaust side is going to offer quick response, but will choke the motor up top. Alas your predictions are coming true IGY... I just took a run at 12 psi and it felt like choking after 6500 rpms.. https://www.nopistons.com/forums/pub...O_DIR#>/11.gif https://www.nopistons.com/forums/pub...O_DIR#>/11.gif https://www.nopistons.com/forums/pub...O_DIR#>/11.gif |
Also i had wrapped the dump tube and the pipe from the manifold to the wastegate in glasswool with aluminum to insulate the heat... when i took the car out with the single turbo first time it gave some burning smell and white smoke which scared me but i popped the hood when i got a suitable place to park everything seemed ok... then i kept running 7.5 psi and no smoke.. but today i ran 12 psi for 2 runs and smoke can in from the firewall as i had forgot to put the rubber back in after i brought some wiring in from the engine.. i stopped after 3 mins and everything seemed ok but some burning smell.. what can it be?? does the glasswool doea this the first few time or will it keep doing it forever??
u can see the need for the insulation in the pic in my other post choking up top in the same forum... thanks |
Strange boosting problem..
Ok my car started boosting OK with this turbo under 6500 rpms the power was good.. but then i decided to ditch the midpipe and put in a resonator.. when i did that my car did'nt want to boost over 8psi max.. it would boost to 8 psi at aroun 3500rpms and then drop to 6 psi.. So i put the staright mid pipe back in without the resonator... the problem was still there I came home and this morning checked to see what the problem could be... I checked the silicon hose from the turbo going to the intercooler was somewhat loose.. I mean if i pulled on it real hard it seemed little loose so i figured it cud be the reason.. So i tighten it.. took the car for a run now it started boosting till 9psi but then the same hesitation at 4500rpms+.. Then i increased the boost from the boost controller and now it would boost to 12psi but then the same thing at 4500rpms... Now it cannot be a boost leak can it.. cuz it does boost to 12psi everytime but starts hesitating at 4500rpms... How can it be... it was fine 2 days back.. Also since its a right hand drive car the turbo is quite near me.. i can feel when it hesitates that boost is leaking from the silicon hose right off of the turbo.. Please help.... |
