Hybrid-RX8

Looks like an amazing project Alex... Don't forget to get that external wastegate going.... Why bother using the Greddy turbo though? With the amount of money your dumping in fortifying the car..(it looks like your spending along the lines of 15-20G's for the total in parts and install)... it seems almost a waste that your essentially only using an 18G when there are so many other more efficient turbos on the market.. hell you've got the engine ripped it... why not fabricate a manifold?

It'll be nice for someone to running an F-CON PRO.... definitely got to keep in touch about any problems and such..which hopefully there are none..

i think the fab costs are high, at least Blast's pricing and I was on a budget too. The cost is actually under $11K for what I've asked for, 400whp and reliability. As far as wastegate, I should ask them why this isn't on the list.

I really like talking to these guys because they really do "keep it real". I was paranoid because forum ppl would pm me with issues. Blast said that the car isn't running that high of HP and that a car is no rocket ship or drag car .. so there's more elbow room.

The one thing these guys is they're keeping certain things to themselves, as a Blast customizaiton.

I got the kit because the turbo was rated for 450whp (unreliable), figure my range was definitely in teh range for reliability. As far as manifold, I think for the price of the kit and overall project, its okay to go with a "no so perfect" manifold design. I'm not looking for a 500whp supercar .. I was told if I wanted 500whp, that it would cost me about 5-10K more than what I'm paying. So I was financially stunned with that comment .. so I figured be happy w/ what I set out for.

I'm trying to stay confident in their work, they do a lot of work my friends cars and another member who knows rotaries knows these guys too. I figure if I stay confident, nothign will go wrong :p

bump for updates

so... what's up Alex? How's your project going?

I thought it was supposed to be done in June ?

alex

forgot to update, the motor and the parts were stuck in japan until late june. Blast finished the install of the greddy stuff and all the internal work. they have the motor running as of last week. They told me I had to break in the new parts before they can start tuning the car more aggresively.

Some recommendations from the kit was the intake manifold, they thought, is sub-par. They're willing to custom make an intake manifold but if they went that route, they'd rather see a better turbo.

They also will have to swap out my RB exhaust for a custom 3" piping one too and I requested that they use a single muffler design.

I'll have some pics soon .. a friend took some pics while at blast (he works at C-west) but the car was raised at the time, so no real nice photos. I asked if he can take sound clips but, we'll have to see.

So, the motor was sent to japan, hence the 2 week delay. Eventually, I'll hit up blast on a weekend that they are there and have to break the motor in (1k miles).

All looks good so far, except the greddy kit but it'll suffice for now.

Oh, another note, I am thinking of changing out the throttle bodies for a mechanical one ... blast is researching this if it would make things easier when they deal w/ the drive-by-wire system.

If you are keeping the GReddy turbo, you may want to have it upgraded at Mazsport or elsewhere, since people are finding the limit of the turbo itself to be 300whp. I'd hate to hear you spending all that money, and me be able to beat you

IZoomZoomI

I think they know what they're doing They were looking at 400 whp... with a greddy turbo, not just 300 whp. Now if they can get that done thats the question, I won't be surprised though, dumping all that cash in I better get my 400 whp with reliability.

Moostafa29

They were looking at that much power because they thought the turbo itself could push it that far. But we have all seen that it can't. I'm sure with all the internal upgrades the engine itself could take the abuse, put getting the turbo to actually reach that level has been proven quite a few times to fall short. If they found a way to push the stock greddy to that level, then hats off to them.

Moostafa29

Bump!

alex

Haha, I forgot to update this page.

Well, they're currently working on the electrical side of things. They were telling me how the CAN system on the RX8 is integrated much more than the Nissan systems. In the midst of working out the electricals, they hit a problem w/ the key; apparently starting the car often made the key lose its code. So, I currently shipped them another key and for now, if anyone knows if what CAN error code for the immobilzer is? even if it does produce one?

For now, I am pretty sure we may have to switch to a manual throttle body but not sure if this is an easy work around or not.

if anyone wants to go to LA, I'm very much a last second person, it might be this weekend to check out my car and to finally get the final information on what they did on the engine.

Being this weekend is sevenstock, most of us are caravaning down to the south. Not sure if it's a close location for you or not, but you should go even in your mx-5.

bump...updates please

IZoomZoomI

The guy fell off the map, he should be out enjoying all the extra hp by now.

Pololo_RX8

Last thing I heard is that he is still waiting for the car to be finished... What a mess.

Sorry, I went to this place a couple of days ago, all the hardware is installed with the exception of the stock computer. Without divulging too much, Blast decided reprogram the stock ECU to bypass some of the CAN functionality. I believe most of the time when they tried to do some stuff to the electronics, some other system was always in trouble, like ABS, power steering, DSC, etc. While I said I wanted to keep all that stuff, they decided to have the PCM completely reprogrammed.

Delay shipping the unit out to japan, to a person who can update the pcm and sending it back.

alex

ps: not fallng off the earth but traveling way too much.

IZoomZoomI

^^^ haha good stuff. A reflash huh?

XDEEDUBBX

good luck man..i know blast has a good reputation...

sorry, I've switched jobs recently and I'm doing a crap load of traveling.

but, as for the car, in about 2 weeks, I'm going to have to drive the car for about 1000 miles and afterwards, they're going to retune the car.

I had the stock ecu reprogrammed to deactivate certain controlls. this was done by someone in japan, and, (yet another) that was a source of a 1 1/2 month delay.

I think if I were to do things over again, I'd use a Motec :p but that was just too pricey.

Moostafa29

Have they been able to dyno the car in its current form? If so, what numbers did it put down? If not, what are their whp expectations? Sorry to hear its taking so long btw.

alex

all I know is, when they started the car up, and with the custom downpipe they made (3" all the way through), it sounded completely different from some other sound clips I heard from other rx8 w/ turbo's. but I want to hear and see your [Mike] car though

They are definitely expecting to hit 350whp easily, I was told that # is definitely attainable but they'll do a dyno for a MAX result (marketing thing for myself :p ) and they expect around 420-430whp but this would be after break in and after they tune for 350whp.

I had originally wanted 400whp but they were telling me to leave it at 350whp since its a bit easier to drive around for daily use.

when I break it in, I plan on trying to meet up somewhere since I need to put miles on the car and, maybe, I'll let ppl help me break the car in.

i'm still in the hunt to get new coilovers and bigger breaks still. but for some reason, I have no money

gh0st

never heard of a greddy getting the 8 above 300hp. hell.. i dont even see 400whp happening with a gt30r.

denward

Moostafa29

He has custom engine, exhaust, and ecu work done.

gh0st

as far as the motor goes, he is getting FD rotors and strengthening everything else right? i dont think ive seen FDs hit 400whp either with a t618z. doenst matter how strong and how much boost the motor can handle, you loose efficiency after 14 or so psi anyways. but then again... i kinda just skimed though.. maybe there is something i missed
