Hi everyone ,

I was thinking of using a percision 7168 on a built rb25 with auto behind it

Was thinking to use a ported h front cover

What size rear housing should I use (.68 .81)

Has anyone used one of these, what sort of power would I get (18-20 psi for street ,28-35 psi for drags)

Was thinking about e85 but not shore. Closest e85 is about an hour away

Need to decide on turbo to built custom manifold

Any info / advise would be very helpful

Thanks everyone

Argh people really need to mention power targets when saying they want a turbo suggestion. What are your targets? If you are going for 35psi for drags I am assuming a lot, and you're going to need to run E85/C16/Q16/something which can handle the associated pressure.

Please clarify

[Aldawy]

I was thinking about 350 kw for street & for the drags, I'll have to boost the hell out of it & hope for the best

I want to get at least a high to mid 10 in street trim, & for race at least a mid to low 9

I thought I might have to run e85. It will make it easier for racing (load up race tune, put the slicks on & hold on)

[SCR48]

You can't run those times with 350rwkw.... If that's your power target then a 7xxx turbo is way too big

[Aldawy]

What turbo would you suggest to use to run the times

The engine is going in a VN commodore

Not sure how well a RB25 would go with an auto and that large a turbo - you won't be getting full boost until around 6000rpm at a guess, and mid-ish 10s with 350kw would be pretty damn good going too, depending on the chassis.

If you are split between E85 and petrol for practicality, just go an ECU (and tuner ) which can handle flex fuel tuning. Are you specifically after a Precision turbo? FP have turbos which are a tad insane for sale at the moment which would be pretty mean for aiming for low 9s - again depending on overall setup: http://store.forcedperformance.net/merchant2/merchant.mvc?Screen=PROD&Store_Code=FP&Product_Code=NTFPSUPER94&Category_Code=Turbo-FP

Can be attached to a T3 manifold and make pretty much all of the power, and while it would be hardly a street turbo it will provide a huge amount of power for the spool and is very very cheap (at the moment) for what it is. If you are looking for turbos of this hp area (1000hp+) then you're going to need some serious engine work - headwork inclusive if you hope to get everything out of a turbo of this size on 'up to' 35psi. Otherwise something like a Precision PT6466 or something of the sort wouldn't be a silly choice.

I think the faster times he was aiming for the unnamed "race" power level - 350kw was street mode.

A 6262 would do 350kW through an auto standing on its head and have the response to match.

[Lithium]

Easily. But if it's hypothetically capable making that power on 20psi through an auto, I doubt it will flow enough to supply enough air to boost the same engine to 35psi

For all intents and purposes he's asking for a turbo which would make 600rwkw (give or take) through a manual on E85 from what I can tell

[PJ.]

Sorry dude, I only read the post above mine which was 350kW.

Sure 35psi is going to need something a bit bigger, I would be shooting for a 6766 to run 35psi through an RB. What's 3mm between mates

[Lithium]

Lol Yeah the wording was a bit hard to follow, I had to read the post a couple of times to get (what I think...) he meant.

Yeah making that power "nicely" I think would involve a nice modern 67mm turbo - so yeah, PT6766 and also the Super94 HTA I mentioned (which I have an ulterior motive of just wanting to see how mental they would be on an RB haha)

[Aldawy]

The pt6766 looks good ,what housing would be best t3 or t4 & what size for the rb25

[GTScotT]

T4 split pulse .84 or 1.00

[Joshbigt62r]

What he said ^^^

[SCR48]

T4 split pulse .84 or 1.00

This is what I went with the 6466 DBB, split T4 .84

[G37Sam]

I would personally run a 1.00 ar on a 6466. I feel the 0.84 is more suited for a 6266.

[BCNR33GT-R]

What would be good for response and power to go for precision turbo?

Looking power terms 450 500hp

Not to laggy as mainly daily street driven.

Don't know much about single setups I've got 33 Gtr stock turbos looking for something different soonish.

Regards

[G37Sam]

I would do a 6262 with a split 0.63 (450ish) or 0.84 (500ish)
