Never heard of out, Forced performance do their own hta turbo with a similar name though which I don't know of anyone using on an rb but I recon it would be a good high power combo. I know someone with a 3586hta on an rb30 and it makes over 500kw on e30 with awesome delivery.

In this thread you will find results from 3788's, try to remember they are bolted onto big budget RB30DET's and not your average forged motor.

Considering there are 4088s and 4094s I have no doubt that garrett has simply mixed and matched some existing parts. IMHO I would expect the 3794 to be a little better under the pedal and make roughly the same power as the 4088. With the 3788 still being the pick of the bunch.

In the GTX thread I already told you to search and that if someone had one it would already be posted. Moving on..

They actually seem to push more than 4088rs in the cases I have seen, interestingly enough.

Yeah, power capability of approx the 4294 but the response of something like a T04Z

Only a turbo you would select for making easy 600hp at the wheels or pushed hard to 800hp at the wheels with the right fuel.

We use the 3788 as it's better suited to what we do/need

For anyone that is interested, these seem to get less attention than the PT67 turbos but I've been a little more fascinated by these.... haven't said too much as I've been keeping an eye out for results on these things for AGES which are closer to indicating what to expect for those of us who don't want to have to rely on E85/huge boost for making good power and good spool - found that someone has run one on an XR6T and made really good power relative to boost level on one, despite being on a fairly basic setup with stock manifold etc. 400kw on 1bar on pump gas, for example... and sounds and spools awesome!

So now I'm pretty much convinced this would be a gun turbo for a big power RB that retains some form of streetability, they've made >900hp @ wheels on E85 (American dyno style, but still equates to >600kw @ wheels Dyno Dynamics if you take in account the differences) and pushed various Mitsis into the 8s.

Need to somehow fast track finding money to build an RB30DET suitable for such a setup :)

So, a 2litre EVO in the USA just put down 570awhp/425awkw on pump gas using a FP GT3794HTA (they did the 1.2 correction trick a lot of UK workshops do to estimate Dynojet/BHP type figures to get 684hp) - pretty impressive result all the same!

Mods:

· FF Shearer HTA3794 kit

· Magnus Intake w/ 65mm TB

· Buschur twin fuel pumps, ID2000 injectors

· Ported head, stock size valves and Kelford 280 cams

· 2.0 Liter Built

· Sparktech Pro CDI

· AEM EMS

So its 580rwhp with god knows what air temp, ramp rate or boost.

Cant be compared to anything....... Weigh the car..... run it down the strip.

If its 3000lbs and does 140+ then its about right.

Yeah im always suspect of DD graphs without te most important data visible. In fact we just did a test on a Mainline 4wd Dyno (new) and found quite a few variances in power outputs by changing very little 160rwkw first run r configure then run 200rwkw just by a few keystrokes...just to easy to fudge figures. Need to have the full story with dyno sheets.

Fair enough, I'll keep the thread up to date with anymore info - its in the US and most people don't trust DD anyway so he is going to re-run it on a Dynojet. They sound like they expect it to do >140mph traps.

^ yep, that and its running on a 2litre engine - life needs to make as easy as possible to make that kind of power.

Black bnr32, I'd love to see some dyno plots of EVOs making 420+awkw on a Dyno Dynamics dyno running straight 98 using a GT3582R.

I always used to love DD because I think they give more realistic figures compared to hubbers, but after using the dynapac lots now I'm converted. The ability to have such repeatable and consistent results so you can actually compare cars and/or modification effects is awesome

    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way. Simples
    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
    • OK, now we are ready to get started. You need to remove the air boxes on each side for clearance. The cover is straightforward, undo the clips on the top and lift the front cover out of the rest of the housing. If it is tight you can remove the air filters first. The rear section of the airbox is trickier. On each side you need to remove the Air flow meter wiring which is held to the airbox with a clip; you need to get behind the clip on 2 sides if you want to remove it without breaking it - unclip the harder side and pull on the clip with medium force, then unclip the easier side and it should pop out The airbox is held onto the intake hose with a spring clamp; you need to get a flat bladed screwdriver behind the spring on both sides and pop them outwards. When you have got them in the right unclipped place they will stay there and the airbox slips out pretty freely. Put a rag in the intake to prevent anything getting dropped in there, and also to prevent you seeing that the turbo seal is leaking oil (as they do). Then. The top of the radiator is held by a steel plate, it is secured by 2x10mm and 2x12mm headed bolts . Remove them and remove the plate Also grab the bushings that hold the radiator to the plate on each side so they are not lost!
    • Next, remove the upper and lower radiator hoses, both are held with a spring clamp. While you are under there, tackle the Auto Trans cooler lines.  Again both are held on with spring clamps, and as mentioned above you should cap them on the radiator side with an 8mm cap, and on the car side loop them with a length of 8mm pipe - this will stop you losing a dangerous amount of AT fluid during the rest of the job If you've been meaning to add a sender for AT trans temp, this is a great time to do it; put a sender fitting into the passenger side line as that is the inlet to the cooler/radiator.
    • Next you need to remove the intake duct (as with pretty much every job on these cars), it is a series of clips you gently remove with a flat bladed screwdriver. They do get brittle with time and can break, and I have not found a decent quality aftermarket one that fits (they are all too soft or flimsy and don't last either) but the nissan ones are a couple of bucks each (ouch).  Once the clips are off (either 8 or 10, I didn't check) you lift the intake duct out and will see the reservoirs Undo the line into the radiator side cap (some bent needle nosed piers are awesome for spring clamps) and then remove the 4x 10m nuts that hold both in place.  I didn't get these pics, but remove the line under the radiator reservoir (spring clamp again) then remove that reservoir. Then you can get at the intake reservoir, same thing, spring clamp underneath then remove it. BTW This is a great time to put in a larger (+70%) combined reservoir that AMS makes..... https://www.amsperformance.com/product/q50-q60-red-alpha-coolant-expansion-tank/ They also make an Infiniti branded and part# version if that is your thing
