Hello.
I have an Fd with a rebuild engine. Now i wonder since i gotten used to the performance with it and want to go E85 Single turbo. What turbo and so on should i get to make the car do a 10sec run with a normal person behind the wheel ? i have no problem shaving of 40km/h at top speed if that helps and remove power-steering and ABS

specs as it stands right now

matchported engine
2pin dowel
ra super seals 2mm
2x1600cc injectors on secondary
2x850cc injectors at primary
cosmo fuel pump
different FPR
greddy profec B spec 2 boost controller
Apexi powerFC
Blitz FMIC
and the list goes on

will also be running mickey thompson ET/Street 26/10.5/16

thanks for your help

What turbo and how much boost?

janrx7

gt42 or t04z are the easiest route. You can get over 570whp with any one of these and this should get you into the 10s with normal person driving skills . I see you don't have a hks twin spark, this is a good idea at this point.

Also upgrade the stock drive train. It is a ticking time bomb at this level. Get a kaaz lsd, some cromoly axles and a brace.(If you want to do this right. I have seen people running 10s on a stock diff. A good clutch like a act solid race disc 4 or 6 puck.

robzter

ok. i have an exidy clutch disc. kaaz LSD if i remember corectly.

i was thinking of getting a turbo like T60 or T70
i was thinking of getting a jacobs but maybe the HKS is better? how about launch controll? the axles if i tear them off ill change them what is a good brace?

The t60-1 is the same as the t04z just that the latter is a ball bearing unit. I don't jacobs, but with the power fc, nothing is better than the hks twin spark with stock coils. Here the are at least 3 fds running 10s with similar setup. You should buy a banzai or PFS diff brace to prevent wheel hop.

The first turbo is too small for that horsepower. You need a turbo of 70mm and .96 exhaust at least. The second should do.

robzter

so the GT45 is to big? i planed changing the coils to MSD instead to get the possibility of getting launch controll

Actually the 60-1 is smaller, 59mm compressor.


I would agree, something larger like a 70mm would work great.

10's on a 67mm inducer turbo has been done, but you will need good traction.

Also if you are going E85 then 850/1680 will not be enough injector. Not by a long shot. And you will need dual fuel pumps or one of those really high flowing single pumps.

robzter

ok injectors are an easy change its just the choice of turbo. im thinking of also buying another lower intake like a xcessive LIM.

I would go with a Borg Warner. They dont hurt the wallet, perform great, and are very efficent. I have like a sc362(little different .81a/r hot side and 61.5mm) and putting down 475rwhp@17psi(lag is not too bad) and with no 2 step on radials i went 11.1@126 on my first pass and blew my diff the second. Think i can get into the 10's and this is a very mild tune(11.0's) from Ray at PFS and i am on water meth and pump. He said 550rwhp would not be an issue(that would be mid 10's) but he would feel safer on race gas and i only like to run pump. I am running, balanced large street ported short block from PFS, 850cc pri 1600cc sec, bosch 044 in tank, hks twin power, fmic, 3in with magnaflow mid pipe to some 3in cat back(like apexi knock off) and apexi PFC and some other little things(boost controller ect.). I have a kenny bell boost a pump and dont even use it right now lol it is a rich tune but rather keep it that way and safe the engine.

1.) Fast Car
2.) Drive better than Ernie and Eric

janrx7

Yeah forgot dual pumps. Preferby denso supra. You could get into 10s with high 400hps but
Easier with 500hp+ since workin on normal driving.

The A/R hotside on those first 2 turbo's is way too small. You want at least a .82 and really something closer to a 1.00 divided. The gt45 is a bit too big and will be lag city. I'm happy with my master power t70. They are right you will need more fuel with e85.

Yes the t60-1 is smaller then a to4z. The t60-1 is similar to the gt35r except non ball bearing. The to4z and to4r are similar with the to4z being ball bearing. A 60mm inducer is capable of close to 500 but it's much more difficult. 70mm+ is a better choice and will get you into the 500's and 10's much easier. Most tracks will require a cage somewhere in the 11's if you plan on running on the track.

I ran an 11.4 on stock twins with 35psi on 1 rotor due to my corner seals blowing because my map sensor line blew off on the previous run.

This can easily done with a GT35. You should be in the low 10's and maybe even high 9s with GT42ish turbo with a decent amount of boost.

All you have to do is know how to drive, have traction, and launch the **** out of the car. You cant be afraid to break stuff. If you are, you shouldnt be drag racing anyway.

WaachBack

iTrader: (21)

Yes, it is too big if you ask me.

The biggest I would go with your setup is a GT42. Ideally, I would run a GT4094R. You could have sub par driving skills and still be in the 10s with a good launch and traction.

forget the 10's. Just get the turn key stock block Enzo special.

I have a 61.5mm borg warner extended tip(flows 65lbs) and 500rwhp is no problem just i wanted my tune safe 475rwhp@17psi(alot more to go) and i spike like 19psi so there is the 500rwhp right there. On race gas Ray said well over 500rwhp would be no issue. There is no need for a 70mm turbo since lag will make it less fun to drive and it will put you out of some classes in drag racing(some go by the size of the turbo). I have full interior, A/c, and P/s and at 11.1 so far(going for 10's next friday). I am on a single bosch 044 and fine on fuel. My turbo is kinda odd though since i have not seen another BW with a .81 A/R so it might have some Ray magic or something. My friend has the bulls eye sc362(.87 A/R same cold side) on his Vw GTI Vr6 and he is pulling away from me but he is spiking 28psi and probably somewhere in the high 500's or more. Plus the extended tip sounds cool.

turboR1

I went 10.6 with 501rwhp on my first try so thats all you need for an average driver.

you can go high 10s with 425rwhp but theres no room for mistakes.

Porting plays a big role in how much power you make on a 60mm turbo. And while you "can" make 500 with one, and thats great if you do, it's the exception not the rule. Most turbo's that size peak efficiency is around 15 psi and max out by 20 psi making them a high 400 hp turbo. A stock port engine would have trouble reaching mid 400's. I used to run a 60-1 and now i run a t70 and you can feel the difference in power, and see how much extra fuel it needs for the same boost levels. Yes lag is more, but he didn't ask about lag. He asked what turbo will easily put him in the 10's. And if he's planning on e85 then big boost should be in the future. No sense in putting a limit of 19-20 psi when 25-30+psi is possible.

turboR1

My stock port engine with a gt35r had no trouble making 515rwhp at about 23psi but it was maxed out after that At 15psi I made 455rwhp. So im going to have to disagree that a stock port motor would have trouble making mid 400s. This was done on C16 first and then again on E85. I think you meant to say tuning not porting plays a big role in how much power you make

And this turbo doesnt max out around 20 flows very efficient quite a bit higher than that and like i said Ray@PFS said this turbo would have no issue past like 550rwhp on race gas@ like 22 or more psi and be in the eficiency range. Heres some of the specs http://www.bullseyepower.com/S300.asp. Mine has a street port so i am not making much more than a stock port with the same same setup. I would almost say this turbo against the T70 would be more efficient but think the T70 flows slightly more. Alot of these newer smaller turbos flow just as much as the older bigger turbos just because of these new compressor wheel designs for example the borg waner extended tip or the billet turbos. Just wondering, what does the t70 setup you have make@17psi?

Will the .81 a/r be a little too small and create more exhaust back pressure than a larger a/r? Not saying it won't work, but I am of the impression that a larger a/r is rotary friendly.

ports mainly determine where the power band will be. yes bigger holes flow more air at less pressure... but the cfm of the turbo determines how much power you "can " make depending on the amount of pressure you put through a given manifold/port setup. This was in response to post 21@22

So you found an optimistic dyno or you're another exception. There's a guy making over 400 hp on stock twins on rcc with 13 psi. But for his one instance there's a 1000 other guys maxing out at 360 with higher boost levels. I find 515 a bit of a stretch on a stock port engine running a gt35r, 450 at 15 psi is a stretch too, but i can't prove you wrong. I can say there's a lot of other guys stuck at much lower power levels though. Tuning plays a role, but there is no huge black secret that opens up another 75 hp from a decent tune. Dyno's are a good bench mark, but if you go to enough of them you'll see they will tell you all kinds of different things. When someone asks what to expect with a setup, im inclined to give examples of the 50 other guys that didn't break 400 hp at 15 psi rather then the one that said he made 455. Otherwise your giving them the wrong idea.
