Hey Luvrx7 - I know you went single recently at KD (and since I would take it there), and anyone else who's gone single...

what's a reasonable estimate for cost to upgrade to a single turbo? What kit and what other "parts" were required?

I already have a Power FC and Apexi FMIC, and a couple of other little things... but I figure injectors, tuning, FP regulator, porting possibly(?), tuning etc are going to cost a ton.

hey LUVRX7, how much did you kit and labor and all cost?

thanks.

Ps. anyone have clues on how much i'd be able to sell my bonez downpipe and twins for? (like 600 or 700 total?) Trying to figure out how much i need to save to go single - and pump out a healthy 350-400 rwhps safely.

 

I bought the XS-Engineering T04e kit from the RX7Store group buy. KDR has installed it and I don't know all the costs yet. Best to e-mail Dave at KDR. KDROTARY@ENTER.NET

Might take a couple of days for him to e-mail you back.

I have a section on my site with what it cost me for going single turbo.

 

Bah! comeon-- i won't use it against dave to get a better price . I'm just curious as to all the parts and pieces and costs and estimates .

Also Styk33 - I saw your site - I AIN'T GETTING IT DONE FOR 800 BUCKS OR 900 BUCKS!!! grrr... - oh, i'm saying this in the nicest possible way . Unless yer around NYC area, and wanna give me a hand in putting one together for me ya know?

 

Turbo Kit $2800
Power FC $1050
Injectors $350
Fuel Pump$240

Thats about it unless you want a larger intercooler. $1150

Sounds like all I need are: turbo kit and injectors -- I already have an upgraded IC and fuel pump. I was planning on doing the boost controller anyways, so we can chuck that in there as well. I've been reading that the Power FC has problems controlling boost above... 14.5psi (was it?), any truth here?

 

17.5psi is what I read. I don't think more then 15psi is all I need, so this a good solution for me.

The limit is rumored to be 17.2 psi or thereabouts. And the problem is not that it can't control boost, but rather that the PowerFC cannot read manifold pressures above 17.2 psi when you are using the stock MAP sensor, and thus it cannot effectively provide fuel injection at boost above that level.

Is it possible to run more than 17ish psi on the PowerFC with the stock MAP sensor? Absolutely, but it is a really foolish thing to do if you value your engine. Don't do it.

You can upgrade the MAP sensor to run higher boost. Talk to the guys at http://www.xs-engineering.com/ to see what upgrades are available.

I put it up on my site because people asked. I am never doing it again. If I had it to do over again I would buy a damn kit. I love making things, but I just don't have the time to do stuff like this anymore. I am always up for giving verbal help, but darn if I am going to make another manifold or piece together parts for the system again.

Jason gives the best option.

clutch might need to be added to that list also

 

oh yeah.. forgot.. when I needed to have my tranny rebuilt (due to 2nd and 5th gear synchros), I had a clutchmasters stage 4 (i think) clutch put in at the same time.

Jason, you wanna start another group buy for a single turbo kit?? hehe...
