I am now looking into changing my 7 into a single turbo.

I want to have anything between 400-500 hp but also be as realiably

modded as i possibly can!

Which turbo setup do you guys think would be the most reliable and produce

around that amount of horsepower. I can put an LS1 in my car anytime

I want because my stepfather's business is building american muscle cars

so all the labor is free i'd only have to pay for the mounts but I've been thinking

lately, the sole reason i got this car is because Not only its a beautiful speciment

but its rare, and nimble. But lately I haven't been able to sleep because

I keep thinking of my motor blowing. So what do you guys think I should do?

1993 FD R1
stock twins
haltech e6k
A couple of other mods.
RWHP @287 TQ @ 228 ( trying to raise tq any advice?) 10 PSI

 

A-spec's 500R turbo will get you into that power range. Many other turbos will get your there as well.

Just about every single turbo setup will be more reliable than the problematic and complex stock twin setup. Make sure you have all the supporting mods for going single turbo. You have the haltech already so your set there. Look into upgrading the fuel system and cooling system if you haven't already.

You can get all the right components and a good tune, but pop your motor the second that your fuel injectors get too clogged to deliver. Advice is to get a wide band O2 and account for any changes you observe. Tune it towards the rich side and you will have some margin for observation. Tune too close to the edge, and you may not get a chance to address issues before you're forced to do so.

ps- local loudmouth who bashed his rotary at every opportunity, does LS1 swap and goes right out and spins a bearing.

You need a single turbo kit:T78,t88,500r, ect. and lots of fuel to power it. I have 850 primary and 1620 secondary. And raise the boost. With my stock injector and non seq twins i raised my boost to 13 psi for a little extra HP.

 

how about reliabilty mods? anything else i should get? to make it more reliable

I want to make it "BULLETPROFF"

P-S. Note the part that says "BULLETPROFF" is a joke.
