My fd has about 170,000 miles on her.She has a fresh atkins streetport motor,but original turbos.They are tired i can feel it.Should i just get them rebuilt,Or new aftermarket ones,Or just convert to a single???

 

personally is this even a question...?? for the price get a single, if your worried about driveabilty just get a 60-1 turbo and it wont have that much lag..

i wouldnt rebuild the turbos if i were you..

but honestly what i would do, for the money send your turbo into bryan at BNR and have him upgrade them to stage 3's then you get new twins that are way more cappable than the stockers, and its great cause all the stock parts still work on it!! thats what id do personally!!

 

It really depends on what else is on your car. If you are pretty much stock aside from the ported engine, then you'll need a few more things besides just the single turbo kit. In that case, the costs won't necessarily be the same.

What all is done to the car currently?

 

Mahjik has hit it just right.

What is your target rear wheel horsepower goal?
What are the current mods?

Going single + all the goodies is going to be a more expensive than just putting in a used set (or rebuilt set) of twins.

 

A nice set of NEW turbos with the later 99+ design can be purchased from RX7.com for about $2,300 and installed with no other changes. BNR Turbos are about the same price or a little more and also bolt right in but you can potentially make a bit more power on the BNRs by running more boost - provided you have a good tuner and supporting fuel and flow mods.

Single turbo will require much more time, effort and money.

 

well i recently got this car ,the work was already done, mods are:pettit ecu, apexi air intake,apexi downppe and full exhaust(no cat), ported motor, and thats about it i think i have a larger intercooler but havent installed it yet...runnin at about 12psi

 

i dont want a race car,just something that has the power there when i want it.I think i would be happy around 325-350 hp

 

With that, the minimal things you would need for a small single turbo setup would be the single kit and a programmable ECU. You cannot run a single turbo with the Pettit ECU. So that adds about another $1000 onto your single turbo upgrade.

You can do that with stock or upgraded twins. IMO, I would look at one of two options:

1. Good set of used stock twins. You can usually find them for around $300-400 USD.

2. '99 Spec Twins
