Hi...which single turbo will let you run stock fuel system and intercooler. Looking for a stock twin replacement but dont want to upgrade anything else. Will be runnign a max of 12psi. I do have a PFC so it will be tuned.

 

none

 

12psi and a stock fuel sytem/ic will net you no more power than you could get out of the twins.

sounds like you're just scared of the sequential setup. get a vacuum job and perform some simplification or switch to parallel mode.

 

no i luv the seq setup i just hate rebuit turbos....how about the TD06?

 

there's not a kit for the TD06, is there? there aren't any no kits that are available that allow you to use the stock fuel/ic. why spend the money on the single turbo when you could spend the money on twins (rebuilt, bnr stage iii, whatever) and more upgrades for your car?

 

I have tuned a couple of cars w/TO4E's and ported motors on stock injectors to about 11.5 psi and then you are out of fuel. This is safely tuned with upgraded fuel pump and intercooler. I also ran a TDO6 20G on my car for a little while boosting 15psi. I had a front mount intercooler and a walbro fuel pump. If you go the stock inj/ single route at the least I would recommend some sort of upgraded intercooler and fuel pump.

 

Greddy makes a td06 kit for the fd, but no single will work properly on a stock fuel system and intercooler. Doing so is just plain stupid in my opinion. Stick with the twins, maybe go nonsequential untill you are ready to upgrade everything and do it right. Its going to cost alot more when you blow your motor from half-assing it. Rebuilt turbos can be had for less than a third of the cost of a single kit. Look into BNR. The offer a stock rebuild with warranty for less than a grand.

 

At 12 psi on my T04e kit, I'm only hitting about 60% duty on a 550/1300 combo with a SMIC. You've probably got room on the stock fuel system to run 12 psi with this turbo, and you should definitely be able to run 10 psi.

You're not going to be happy for long, though. Might as well upgrade the fuel so you can turn up the boost. You've got to get under the LIM anyway to clean up the hoses as part of the single conversion. It would be a waste of time not to do an injector swap while you're in there.

 

Im going to disagree on this one. Not everyone goes single to gain power. One big advantage is the tremendous amount of heat reduction as well as simplify your whole system.. You can do a really small single on stock setup and be ok, could be alot better but it is feasible. I am NOT saying that doing other mods wouldnt help tremendously but at around 8-10psi on say a T3 you should be OK. I would always recommend doing your fuel and management sytem but ive seen plenty of cars with stock systems and small singles.

 

T3???? I would seriously like to hear the logic behind that bad choice, unless of course you are talking about 2. The smallest exhaust side I would go on a rotary is P trim AR .84(this is what comes on the HKS TO4E kit). This gives good response with less exhaust restriction, less heat which equals better reliability. All you are going to get with a T3 is less power than stock higher air temps from the over worked turbo and higher exhaust temps because of the restrictive exhaust side. Leave the T3's for the Hondas.

 

here is the deal either i get brand new 99 twins or i get a small single with no lag. I want around 350 rwhp. I'm not into drag racing and just want something that will last long with my brand new stock port motor. No BNRs as i have tried those and rather not go into details so unless your are running those and making power dont recommend them based on all the hoopla.

I do plan to get an IC but not now so what i really want to know is can the stock fuel system handle a small single turbo max 12 psi. I have the PFC so it will be tuned. Here is a link to TD06 which is what I will probably go with http://www.rx7.com/cgi-local/3catalog.cgi?cat=9&part=7

 

i don't run BNR twins. Don't have an FD.
Three out of five of my FD-driving friends run BNR Stage IIIs. There are a number of people on the forum who are happy with them. What was your problem with them, and which set did you use?

 

. I did not say to get a t3 as i personally think that if your not going to do other mods you shouldnt waste your time. Rather if you are going to run a single w/o doing anything else i would just keep the boost under 10psi with a very small turbo. I was giving the advice of getting a small turbo and using a t3 as a reference, as i have no experience installing singles on totally stock motors, just have seen a handful of cars coming from Pettit and various other places with stock everything besides for T3, T3/t4,and small hot side t4. And also, not trying to be sarcastic, what is your logic of explaing how a t3 is "overworked" at 8psi and would cause any higher temps than the stock twins.

 

Basically what hes saying is that the motor flows more by it self than with the turbo. Something that small will be done in no time and would just be blowing hot air and not making any gains at all.
I also agree with if your going single do it right the first time....what you try and save now WILL end up costing you a lot more later on.

 

Not over worked at 8psi, but overworked at the boost you would have to run to make 300hp. 8psi on a T3, you would be better off running NA. To make the same power as the stock twins the T3 will cause higher air temps.
