I'm tubrocharging an NA Porsche 3.2 Carrera and need to source a turbo for it.  Second hand, rebuilt, I don't mind as long as it does the job and isn't drug money.  Specs are:

T3 inlet, Vband outlet, ball bearing, A/R 0.82, 350 - 500 hp, external gate

I'll take recommendations on brand as well as I'm relatively unfamiliar with turbo brands outside of Garrett.

I'm in Vic so that's a preference.

Cheers.

If you're not brand-conscious then consider Garrett, Borg Warner, Precision, Master Power, Kinugawa.  If you want one built specifically for you, Melbourne based then talk with Hypergear.

As to sourcing them, there's plenty of comments throughout this forum where to look.

Possibly won't be a lot of direct experience with Porsche engines on a Skyline-centric forum, but if I recall correctly those early spec 70s - 80s air cooled engines were (by RB standards) lower revving and fairly low compression pumps. But they did run a solid hit of boost and performed strongly if you could keep them in a boost friendly rpm range.

If you're looking to boost a high-comp donk, best be speaking to people with Porsche experience, and considering how you're planning to fuel and tune it.

Could be a great experience, would like to hear more as you go along.  Being Euro the engine will no doubt have some demanding requirements, but the turbo choices will be broad.

 

 

Thanks mate. There is a well trodden route for turboing an NA Porsche 3.2l flat 6. Turbo, injectors and programable ECU, and other obvious items. Just needed a steer on turbo brands and where to get them. I visited Tao on Friday and a mate dug this old Greddy unit up for me so there are a few options. IMG_8344.jpg

Turbine housing will be too small on that one. I'd suggest an Borg Warner airwerks around s257 / 7670 / 8070 size. 


Thanks. Too small for what? Bear in mind initial set up is 7psi and 350hp. Turbo is gong to cost very little so it’s probably a good place to start unless it’s stuffed or really inappropriate for the application. There is also the issue of packaging as there is not a whole heap of space at the back of the Porsche engine with the rear bar, engine tinware and rear engine mount all conspiring against you. All of that said I’ll def look into the turbos you suggested and thanks for your input.

    • There's plenty of OEM steering arms that are bolted on. Not in the same fashion/orientation as that one, to be sure, but still. Examples of what I'm thinking of would use holes like the ones that have the downward facing studs on the GTR uprights (down the bottom end, under the driveshaft opening, near the lower balljoint) and bolt a steering arm on using only 2 bolts that would be somewhat similarly in shear as these you're complainig about. I reckon old Holdens did that, and I've never seen a broken one of those.
    • Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go. 
    • The roof is wrapped
    • This is how I last did this when I had a master cylinder fail and introduce air. Bleed before first stage, go oh shit through first stage, bleed at end of first stage, go oh shit through second stage, bleed at end of second stage, go oh shit through third stage, bleed at end of third stage, go oh shit through fourth stage, bleed at lunch, go oh shit through fifth stage, bleed at end of fifth stage, go oh shit through sixth stage....you get the idea. It did come good in the end. My Topdon scan tool can bleed the HY51 and V37, but it doesn't have a consult connector and I don't have an R34 to check that on. I think finding a tool in an Australian workshop other than Nissan that can bleed an R34 will be like rocking horse poo. No way will a generic ODB tool do it.
    • Hmm. Perhaps not the same engineers. The OE Nissan engineers did not forsee a future with spacers pushing the tie rod force application further away from the steering arm and creating that torque. The failures are happening since the advent of those things, and some 30 years after they designed the uprights. So latent casting deficiencies, 30+ yrs of wear and tear, + unexpected usage could quite easily = unforeseen failure. Meanwhile, the engineers who are designing the billet CNC or fabricated uprights are also designing, for the same parts makers, the correction tie rod ends. And they are designing and building these with motorsport (or, at the very least, the meth addled antics of drifters) in mind. So I would hope (in fact, I would expect) that their design work included the offset of that steering force. Doesn't mean that it is not totally valid to ask the question of them, before committing $$.
