Precision Billet Turbos

[rondofj]

Made 286rwkw from 5558 on stock mani low mounted 98 fuel, boost 18psi dropping to 16. Told tuner to push it to 20-22psi but intake temps getting too hot. He said forward facing plenum will help cos it doesnt run along radiator and over exhaust cams as stock piping layout.. Its cold beside battery tray but heats up the next few centimeters.. Oh man that damn 300rwkw

Good work Ron!

How does it feel on the road? Does it compare to the 335kw machine you went in?

Also, who tuned it? JEM?

First impressions- L-A-G----- boy its as doughy as f**k, maybe at 60% of the stockers response up till 3500rpm, after that its coming coming then 4000rpms WHOA BANG it fkn grenades like a rocket, not much difference in seat of pants feel to the 336rwkw car, feels almost, say 90% as mad when boost is on its on! Skates and wheelspins a bit but not too mad, its awesome but the lag is just way too much, I havent driven a ' proper turboed' car so cannot judge, when I come back frm my overseas trip on Jan, u can drive it and gauge Jase, love it but the lag sucks, theres no power below 3200rpms... Is this how its suppposed to be?? 2990rpms=60kw, 3790rpms=120kw, 4720=225, 5470=260kw, 6660rpms=286rwkw

Cant upload dyno graph from iphone in the dyno results thread damn.. Anyways fullboost 18psi around 4000rpms and drops to 16psi from 5700rpms, JEM are awesome, ADAMs a top guy definitely recommend him really goes out of his way to help and explain, takes his time to go through detail by detail

sounds a little bit laggier than my old GTST with a 3071R on it... mine was tuned at 20 psi... see attached dyno

the different is the PT will have a lot more in it! chuck it on e85

[Lithium]

Sounds GT35R like, if you load it up from low rpm in 4th when does it get 18psi?

[rondofj]

Havent had chance to try that yet haha. When i get back from overseas trip, yeah I thought this mite be like a GT35 even tho i never been in one lol

I wonder how that would compare to a standard G3 type B... For on road feel anyway.

Get the sheet up when you can, I would love to see it.

Hi guys,

I've been following this thread with quite a bit of interest and thought I'd share some info on my project.

I running an FJ20det which I swapped from my old DR30 skyline into my 1600. The previous turbo setup used a Fantasy split pulse single waste gate manifold and a twin scroll GT3071r and made 265rwkw on 22psi.

I have since built my own twin scroll manifold with twin waste gates for the 3071r. I have also built a manifold for a Vband in and out Precision 5558 which a friend of mine sources from PJs Quick Bits. I will be doing a back to back test of both these turbos on my FJ in the next few weeks and will post the results.

Cheers

Awesome that will be interesting, what fuel and engine spec? That Precision turbo should have a big edge on potential for power advantage but may need to be pushed harder than 22psi to prove it's extra lag is worth it

[JGB1600]

The engine has been rebuilt with forged piston and port work to the cylinder head. Cams are still standard. I will definitely run som proper boost through the 5558 as that's what they are made for!

I currently run two maps and I will have both tuned for each turbo set up. One for pump 98 and the other for pump 98+water injection provided by an aquamist HFS3 system. Made 295 rwkw @ 28 psi using pump 98+water injection with the 3071r. This is compared to 304 rwkw using c16. I can't speak highly enough of the water injection and once you have set up and tuned it, it's cheap as chips to run. 30 rwkw when ever you want for under a grand fitted and tuned! Can't argue with those results!

[Lithium]

Wow that is real impressive for just water injection! Looking forward to seeing results

I can not wait to install my kit!

[Trozzle]

28psi? Surely that's a typo.

I dont think it is.

[Trozzle]

I dont think it is.

that's not why I questioned it lol, look at the power he made. 295kw. Given that he also said water injection = free 30kw, a 3071R would make 265rwkw on 18psi without hassle. Not 28psi lol.
