Hi gents,
did a bit of a search but couldn't find a topic in which the collective forums knowledge discussed bolt on turbo options for a forged or standard 4G63.

Seems like there are quite a few options available these days (eg FP, GT pumps, etc), but I was wondering if there was a clear winner these days in terms of good spool and/or outright performance.

I'm hoping that the forum can discuss this objectively, rather than blindly fanboi'ing whatever turbo they run themselves and rubbishing anything else.

Looking forward to hearing people's experiences and feedback.

What sort of power level are you hoping for? And what's the use? Do you need quick spool out of corners on a circuit or is it a drag car?

Good questions! I guess I would hope that this becomes a sticky, so most likely for a typical "street" car.

As for my own situation. Car in question (Evo1) has a stock engine, with usual bolt ons (exhaust, filter, bit more boost). Last time it was dyno'd (probably about 10 years ago), it was making around 160-170kw on the Croydon dyno. I was thinking of the FP manifold with a GTpumps (or similar) TD05 upgrade on regular premium (v-power etc).
 
Holset HX35 is what the yanks rave about. I went this route for something different with a BEP rear housing...made it a bolt on affair with an FP Race manifold.
Perfect setup for street and the occasional track day....ripped plenty of people at Powercruise.

How different is this turbo to a TD05 based turbo? What power are you making with what mods? Whats it like to drive? Can you post up a dyno graph?

Thanks!
 
This is that guys summary of it....

I have only run the turbo up to about 20psi. It already pulls like a monster, but 20psi is barely enough for this turbo to come alive. This turbo has a great sound to it when it spools up. It doesn't help the sleeper effect all that much, but it sounds awesome! =) It spools around 3,600rpm. I was hoping for a few hundred rpm sooner, but I have a significant boost leak that I need to fix. Luckily the boost leak won't affect my tune b/c I'm running a speed density setup, but I can't turn up the boost too much b/c a boost leak will over-work the turbo. Bottom line, I'm extremely happy with the turbo so far, especially for the cost! In the end, considering some of the components were gifts and if you factor in the money I made selling my 16g, the whole setup probably cost me around $200! =) Not bad for how much I got out of it.
 
Thanks for the info. Looks like an interesting option. Would be great to see your car in the flesh some day mate.

Anyone else got any practical feedback on the FP or GT pumps options?
 
Im running the FP,HTA68, i have forged pistons 272 cams an the head has had a bit of porting exuast etc, comes on boost very quickly an pulls hard it's only running 20psi atm due to the injectors being maxed out, it makes 230KW ATW, I've run 11.1 at Jambo at QR, an at the roll racing it carves up. I have no experience with any of the other turbos so can't comment there but I love it. I have a dyno sheet somewhere ill see if I can find it an post it up.
 
Hi guys
Just wanting to revisit this topic if anyone had any further real life experience with the following:

1. GT Pumps TD05 20G / 2010ET
2. FP black/green/red
3. GCG turbos highflow
4. GT2835 HKS/Garrett

NB: appreciate Holset was suggested above, but looking for other opinions.

All seem to be about $1200-1500 range.

Not looking for outright perfomance (ie dyno sheet), more quick spool up and driveability.

It will be going on a forged 2L.

Thanks!
 
Cheers guys. Appreciate the feedback!

What sort of power at the wheels would I need to make to run a flat 12?
