Uh, who the hell told you that???

That stupid cut just basically waste about $500 you paid for the turbo exhaust manifold, cause you could've bought a collected version for under $300.

so one small cut, that seems to be part of the design, in my divided manifold make it no better than a fully collected manifold. I think not, but I do agree it would be better without the cut, but it just couldn't be as bad as collected.

No, that cut isn't stock.  The HKS manifolds do not come with that small notch in the divider unless they suddenly changed their design within the past year or so.

You need to brush up on the collected versus divided debate in terms of exhaust design.  That notch pretty much obliterated the advantage of the full divided exhaust design, and the putz who cut that out should be taken out and shot.

I agree 100%. That cut is a bad thing, but no were near as bad as the LOG style collected manifolds.

the putz who cut that out should be taken out and shot.
I also agree 100%...lol

Wow i didn't realize it was that bad. The thing is that it wasn't cut by someone after casting, that cut is part of the cast. Their are no scratches or cutting marks. The cut has the same consistancy with the reast of the manifold. Oh well whats done is done. It still feels great and Im still smiling. I will know better next time.

Thanks guys,

I am still waiting on a dyno date. Some guys are trying to put it together now. Shouldn't be much longer and if they think it will be a while I will just go on my own, cause I really want to know.

Sweet, I would really look at the dyno in Charlotte. That's my home town. I lived in Charleston, SC for the last 5 years as well. All of you FD guys from Charlotte and the area need to hook up with the SC crew. We are a very very close group and we're always looking to meet more rotorheads. PM me if there's anything I can do for you.

thats really cheap. my firend bought turbo's from cheapturbo.com for his 3000GT VR4 and he said they have great prices and service.

but how much did you have to spend on the setup overall? i mean with the pfc and the fuel system and everything because i heard it takes a good $5-8k to go single. is this true?

Yea, Here is the rest of the stuff. May have a few small things missing here and there, but here goes nothing. I did the Fuel last May and the ECU and Intercooler the November before that. So I have been preparing for single turbo ever since I got the car pretty much.

at www.rx7store.net
Apex'i Power FC w/ Commander $1250
RX7 Store Extreme Fuel System $850
ACT Xtreme Street Clutch $505 (traded my stock seats for it)
Apex'i AVC-R $450
HKS Twin Power Ignition w/ harness $547 (don't have this yet)
HKS Frontmount I/C $1289 (the one I have)
or
Greddy FMIC $899 or $1250 (piping to twins or single)
Block Off Plate Kit $65 (made my own cheap ones though)
PWR Radiator $419
Pettit AST $149
Defi' Boost Gauge w/pod $155

at www.rx7.com
RP Triple Pulley Kit for Airpump removal $350

other parts from random places
HKS Racing Bypass Valve $200
Rotorsports Racing Plug wires $80

That is a total of $6244 for the all the supporting mods if your car is about bone stock other than exhaust.

So grand total with turbo and all is.......alot.......$9029

I am sure alot of people would already have some of the mods listed, but that is a total price. Does not include any engine work though. My next step. Buying a core for a rebuild and large streetporting. Then I will be set for life. Haha, probably not.

Well not a whole lot other than there are a few things that HKS has custom spec from Garrett made specifically for them and noone else. But this is not enough to justify the price being 3x more. Also I believe that the back side of the HKS turbo is not a v-band flange but a bolt on one instead. I say save yourself the 2000 dollars from the HKS kit and just go with the kit I pieced together. I'm sure there is more performance with the HKS kit, but not $2000 more. Although it does use their stainless manifold and S/S wastegate compared to my cast iron of each. But you just have to add 400 to the price of my kit and get the same thing.

0110-m-p, "From muffler shop
Get downpipe, dump pipe, and IC pipe made....$150"
I currently need to do this. How did you go about it. I mean they didn't have your car right there to work on, correct? How did you give them the info they needed to built , say the DP, so that it lined up pefectly with your midpipe? Thanks
