After having the FD parked up for 9 months and then 6-7 months ago decided to put it back on the road and get the conversion done at the same time, its finally done. All is left is dyno and ECU mapping.

This thing is going to be a bitch to spool. Not sure about powers but since the engine is not ported it will be limited to what it can achieve.

Setup includes:

- GT4088 Turbo
- 60mm HKS style wastegate
- Greddy style FMIC
- Greddy type RS BOV
- Aeromative style FPR
- Bouch 1600cc secondary injectors
- Walbro fuel pump
- After market secondary fuel rail
- Apexi FC + commander
- Apexi AVCR boost controller
- Apexi RSM speed meter + G-sensor
- Apexi SVAC II air/fuel controller
- Koyo aluminum radiator
- Custom 3" exhaust with decat

I'm sure I've forgot few parts ..

 

You might want another fuel pump! But

 

i just had a very similar setup on my dyno this past week! i was getting up to 20psi by 4500rpms... it climbs like a ******* wall so be ready for severe tire spinning this was same turbo on stock port FD.

you should be able to get 400rwhp on pump no issue

have fun!

 

I have the same turbo and I love it. I have pretty large ports and a 1.06 A/R turbine housing. It spools nicely, about 10 psi. by 3500 rpm. What A/R did you go with for the turbine housing??

 

nice setup !

why

- Apexi FC + commander
- Apexi SVAC II air/fuel controller

little to much maybe ?

 

Think the turbine housing is 1.34 if I'm not mistaken ..

 

I had the SVAC II installed a while back ago when there was no even knowledge of single turbo setups. Probably had it on the car few months after I bought the car. The Apexi FC + commander was obviousely needed for the single turbo conversion.

 

That is the largest A/R made for that turbine I believe, with stock ports you may have some trouble spooling it. See how everything works out once you get it tuned, but I would suggest going with the .96 A/R turbine housing instead, if you are sticking with stock ports.

 

where'd you move the fuse box up front to? Not the 2 on the drivers side but the one that sits above the radiator?

 

Well see how the car do on the dyno next week and try few test drives, this will help to decide if its spooling enough for me or switch to a smaller A/R.

Struggeling to find a HKS style 4" air filter to fit on the turbo and the dyno guys dont want to run the car with the turbo open like this.

 

Its down below between the radiator and the front panel.

 

looks nice man, my poor old 62-1 looks puny compared to that thing

kenn

 

AEM makes one of those synthetic Dry Flo filters, the only problem is, it is 9' long. You seem to have enough room between the turbo inlet and your radiator to fit it though.

 

Usually when people list parts as X Style that means they are cheap ebay knock off crap. I really hope these parts aren't. They are a little too important to cut corners with...

Setup looks nice though. Good luck, hope you love it!

 

Had this thing finally dynoed and the power output was really disappointing. The only conclusion I could come up with is the turbo. I probably need to consider something like T04R/T04Z or GT30 something along this line.

Please look at the dyno and feel free to feedback what you think? Also recommendations on turbos good for 450-500whp in the region of $1200 or near. Has to have a T4 flange so can replace the GT4088 straightward.

 

How many pounds of boost was that run made on?

 

showed that they only took it to 6.3k rpm, why? what was the A/R and boost level?

 

1 bar of boost which is 14.50 psi on 95 Octane .. I wasn't present during the tune but asked them later why didn't they push it to like 1.2 or 1.4 bar at least. THe tuner said to me he didn't know how far I wanted to go and he didn't know the history of the engine and didn't want to risk breaking the rotors tips.

 

Don't know the A/R and why its just at 6300, the tuner set the rev limit to 7200 though. I just bought a used PLX R500 wideband controller from someone so will do some login my self and see if I can up the boost. Injectors were running at 70% cycle so there is room for more boost and fuel to match it.

But I was speaking to someone else today and he was certain that the turbo was just too big for the car specially with stock ports. I'm now looking for 400-450hp rating turbo on the hope this might free some power and also help spool faster.

 

That turbo should be making much more then that at 14psi. A local member here (aaroncake on the board...) is making 386whp(ish) at 13psi on a very conservative tune on that turbo. Engine setup was entirely different but that wouldn't make up the ~75hp difference.

I'd be looking at things in this order:

-tune
-engine health (low compression engine isn't going to put down as much as a healthy one)
-engine parameters. As in, is the FMIC doing its job, how are the EGT's (any exhaust restricitons?) that type of thing.....

 

Clearly not the issue as it seems to hit 1bar pretty easy Lots of guys run that turbo and make good numbers, should be close ~500 at 25psi.

hope that wasn't the same guy who tuned it j/k

EDIT: Check in your PFC what the IGN L is at 10-15psi....

 

I do suspect the tune now to be honest. The engine had compression test done and the results were:

Front rotor: 7.6 / 7.7 / 7.8
Rear rotor : 8.2 / 8.2 / 8.1

These should be good numbers or at least I think so .. I only picked up the car on Friday afternoon and gone to work. Dropped the car to the bodyshop on Saturday to sort the front bumper and wings, so didn't have chance to check anything on it yet.

The down pipe is 3" I think but the rest of the exhaust looks like 2.5", this I discussed with my fab shop today and they said its no problem, they could make me a 3" all way back or even 4".

When I get the car back end of this week, I'll plug in the wide band controller and do few runs and log A/F. Also monitor the boost and check for any leak. I'm just wary of messing with the FC and the settings as I'm not experienced much with that stuff I'm more used to Honda and Hondata tunning on my other car.

 

But what kinda of chances I'm taking if boosting at a level like this? Don't think stock rotor tips or seals will last for long on 25psi!!! Also I'm running a stock map sensor which I belive can read only like 17psi if I'm not mistaken (this is easy to fix I know, probably just get a GM 3bar map sensor).

The tuner tuned the car using a laptop and I'm assuming through datalogit but what are my limitations with the FC hand held controller!!!!

The guy who suggested the turbo was big is different from the tuner.

 

Find A New Tuner!
take it to redline
smaller a/r would help spool-- i run a pretty small .84 a/r with a bigger streetport, spools quickly and doesnt loose too much up top

 

Mate take it to WGT Autodevelopments in Middlewich, near manchester. Have no idea where in the uk u live but, WGT will sort u out verry good. Pip is a master of getting HP out of the PFC. And he will probably tell u where the bottleneck is. It might be the tune, it might be something else. I do belive pip takes about 350£ for a full tune. And he has a dynapac wheel hub dyno.

So give em a call. Think he got betweeen 1-2 weeks wait on tuning atm.
