I picked up my car last night from the shop. Had them install new 99 spec turbos, replace vacuum hoses and install some SPA digital dual gauges. All I can say is WOW. A very nice improvement over the 10 year old stock turbos (I was also having some boost issues which they addressed). The 99 spec turbos spool up faster and give me a few more lbs of boost. It’s nice to have my car running in top condition again. Performance Buyers (PBC) in Chantilly Virginia did all the work and I would definitely recommend them for DC metro area FD owners (shameless plug).

From what I hear, you can go single for the price of the 99's. Why did you go with them? just curious. Congrats.

How long did it take them to do the work after they got the parts? and HOW did you find 99 spec turbos anyway?

Well, for about $500-1,000 more than '99 spec, you can have a single turbo kit sitting in a box at your house... that's still a LONG way from "going" single, as in have a properly-running single turbo car.

Absolutely wrong. With the 99 specs you can just bolt onto a stock car and be done. Single turbo will at minimum need the turbo plus manifold, ecu, intercooler and piping, downpipe, oil supply and drain, air filter etc. You can't go single for $2600 but you can buy brand new 99's for that.

You might be right on the $$ for turbo, but it's the mods to support the single ecu/fuel etc... wise that kills you...

Cool, I wanted to go 99 spec until I found a set of 5k mile 93 turbos for dirt cheap.
I can say the same thing aboutperformance of my 5000 mile new stock turbos vs. the 160k mile old turbos. I wonder how big of a difference there really is between the 93 and 99 turbos all else being equal. Does anybody have any hard numbers?

Runnin Away

Got any run numbers on those 99 Specs....?? And run numbers on your previous turbo set up?

SkywarpR

How many lbs of boost are you running on yor new 99's?

Is your car red i think i saw it at PBC on Mon. If so you have a great lookin car congrats on the new twins.

P.S. my car was the other red FD there.

Even if you plan to run more boost and have to add fuel and ecu mods you'll still spend less money than a single turbo kit would require.

The statement I made was that going to the 99 spec will be cheaper than going single. Can you give me an example where that is not true?

SPOautos

well, if you already have a IC and computer its a toss up. You can get a HKS cast manifold, Tial wg, and a 62-1 turbo, and make some feed/drain lines along with having a dp and IC pipe made for around $2000-$2200 if you cant tune you can add that in for $300 and still be cheaper than the 99 twins. If you already have the IC and pfc I'd go that route. If you dont have the IC and pfc you might should stick with twins. Even with the stock injectors/pump I'd still go single and just run around 8psi of boost.

i dont mean to hijack this guys thread or anything but i have a quick question

lets say you are running non sequential on the 93-95 twins, you swap them out and bolt on the 99 spec twins, without altering anything else, are you still non seq?

i know its stupid question, im assuming it is..

su_maverick

sounds good...with 99's will you need to upgrade your ecu or will you be cutting it close? I am trying to diagnose if my turbos are bad and want to know if I will need the 99s and an ecu. I already have an intake and dp.

Black97VR4

The 99's are basically just your stock turbos with a couple minor improvements. You could put them in a BONE stock car and not need to change anything if you wanted and it would run fine.

If you want to run high boost, a midpipe etc etc, then you will need am ECU and fuel system.

DaiOni

According to what I've read in japanese magazines (specifically, the latest hyperrev rx7 special/parts catalog) - the original release turbos and setup run pretty rich, leaving space for modification. With the later setup - it's quite dangerous to mod (less of a boost/fuel buffer). That, to me, infers that if you already have dp, intake, cb etc - then adding the later turbos definitely requires caution. I think it goes without saying: aftermarket ecu should be in place.

su_maverick

thanks...I kind of asumed that but having a back up clarification is always nice. Just wanted to see if I needed to switch turbos in a pinch I wouldnt have to save up for the ecu as well but I guess it might not be my turbos to begin with.

Here's my fear of paying 2600 for 99 specs: When you pop the motor (and you will), you've probably trashed the turbine wheels and stock turbos, in essence, are not rebuildable. So now you're at 5200 really quick. I'd rather pay 300 for a new P-trim wheel and a rebuild and be on my way.

Black97VR4

If you have the money to do it then go single. A singled car has less problems and headaches than a twin car.

95R2-89TII Ground Zero

I was mislead.

matty

its illogical to go 99 spec if you ask....what are you paying for?

Why wouldn't the RZ (99 spec) turbos be rebuildable?


edit: BTW, just so everyone know, just because they are 99 spec, doesn't mean they are the higher hp ones... if they are not the RZ turbos, then you just have a brand new set of basic 93-95 twins.
