Enjuku/ISIS Turbo kit w/ 3876 turbo

[Blown240sx]

Well a friend of mine bought this kit (not what I would have recommended) and we installed it yesterday.

Little back ground
98 Nissan 240sx
S13 SR Blacktop
Greddy Intake manifold
Greddy FMIC
Trust Downpipe
Apexi GT Spec
Profec B
Greddy Turbo Timer

Then we installed the full Enjuku upgrade kit from ISIS
Deatchwerks 555cc injectors
ISIS 3876 Turbo
ISIS J-pipe
ISIS Turbo Manifold
ISIS intake
Z32 Maf
Enthalpy Tuned ECU

Well time for the review

THE BAD

Honestly the kit isnt terribly hard to install but instructions would be great for people with limited knowledge. It can be a bit confusing and difficult at times. A lot of excess gaskets and bolts.

The turbo looks decent but the spool time is horrid for the HP levels its good for. We are still tweaking the wastegate arm and the Profec B boost controller but we are barely reaching 10 psi by 6K rpms. For having a HP rating lower than a GT28RS it spools worse than my 60-1.

Kit did not come with all the hardware we needed. Luckly I have a few blown turbos laying around and was able to scavenge J Pipe bolts. Missing a coupler to properly line up the intake so it kind pushed against the strut tower.

The gasket sets are cheap paper ones with the aluminum coating. We reused the metal ones we had. I would recommend spending the money on them.

The fittings for the turbo were decent but the plastic braided coolant lines are not a good choice for being near such hot items. We actually had one start to melt already so we turned the fitting as far away from the manifold/turbo as we could. Hopefully it doesnt continue to melt. Stainless braided would be a better choice.

Oil restriction fitting inside the turbo is garbage. It keeps the oil feed fitting that comes with the turbo kit from seating properly and if you try to tighten the fitting down (to where I felt it should be) the threads on the fitting start to strip. I removed the fitting since the actual feed line looks to be small enough restriction. (no signs of "too much" oil yet).

Turbo clearance wasnt very good. We had to cut the motor mount heat shield off to make the turbo housing clear enough to install. Also if you had a Auto car converted to a manual and are still using the Auto brake master and booster, it would be a good idea to unbolt the master cylinder off the booster and move it over by gently bending the lines.

GOOD

Manifold looks well made. Feels and looks thicker than the Ebay ones. I would use this manifold for more than just this turbo. If you wanted to go bottom mount.

J pipe is well constructed but we were missing the bolts/studs for it and gasket is the crappy paper ones.

Price is decent for what ya get


Conclusion

Id buy this kit MINUS the turbo and put a GT28RS on it. The spool time is good on a GT28RS and with supporting mods we have tuned a car to 360 whp on a dynojet @ 16 psi.

Side Note
Id also consider buying your injectors and ECU tuning separate
Id go with 740cc since they are about the same cost as the 555cc and Id choose Nistune or PowerFC but for those who dont tune or know someone Id stay with the Enthalpy.

There's something else going on if you can't hit 10pounds before 6k rpms.. My 3071 spools faster than that... I'm going to assume you were exaggerating. Also, are you seriously complaining about having to cut the the heat shield? I didn't think anyone actually kept that... Exhaust wrap for the win.

First go back and read.

Im not exaggerating if you'd like video Ill be more than happy to post one for you tomorrow.
Please tell me what might be causing this issue? Ive been tuning/swapping/building 240s for 7 years now so please tell me what is the issue that i dont see?

Im complaining since we had the turbo down in there and had to remove the "Bolt on" kit back out to cut a part out of the car. Its not a big deal but seems to me they might want to say "do this first".

[PyR0NiAk]

Video please.

And I've never gotten instructions with any of my parts aside from my S4 cams, my ECU, and my Boost Controller. I definitely wouldn't expect someone to hand me instructions to install a complete bolt-on affair...

Yea who would ever make instructions on installing something you payed 1000+ for.... lol
I dont need instructions to install a bolt on kit but for those who are doing this for the first time with limit knowledge it might be helpful.

Even the Power FC which is a direct replacement has install instructions to unbolt the old ECU and Bolt in the new one.

[DuckyD]

Thanks for the review. There are a lot of questions about the ISIS products and a lot of assumptions. It's nice to hear from soemone that has had their hands on the actual products.

Ill keep updating this thread as we go on.

By the way if you happen to be lucky enough to have A/C, Please ensure your lines are pulled back. Friend didnt listen to me and he ended up burning through one of his lines. Luckily I have a spare.

So does a JWT ECU, but turbos and the like do not typically come with instructions. I'm not trying to be a d!ck to you for writing a review. It's just some of the things you complained about are typical with even name brand kits. I'm running a tomei manifold and a GT3071R. Do you think I kept my heat shield? Hell no. It wouldn't have fit. Either way, decent review I guess..

I'm still waiting for that video. (I'd almost be willing to bet money that if the turbo spools as slow as you claim, that your arm isn't holding the wastegate closed as tightly as it should.)

[Blown240sx]

I thought the same thing but we turned the actuator arm out 3 threads which should have been more than enough. I checked the play on the gate before we installed it and if it was any loose it should have been eliminated when we adjusted the gate.

Im not exaggerating. My friend called Enjuku today and they were very understanding and are allowing him to swap out the turbo for a GT28RS and just pay the difference. I have to say thats pretty awesome of them and they def get positive review from me.

Also the heat shield Im talking about is not the factory manifold shield Im talking of the motor mounts. The mounts have a shield on them that hits the turbo/wastegate flange.

Its raining here but he should be here in a couple hours and Ill have him make a video of it.

[PyR0NiAk]

His tune could also be too rich... That would also cause it to spool super slow..

Enjuku is the s*** btw. As far as the motor mount heat shield, I've never heard of that, but ok, I guess. I used RB25 mounts on mine and most people run the nismo ones, so if you say the stock ones have a heat shield, I have no choice but to believe you.

[Sugar]

Yeah I have a hard time buying that it doesn't spool until 6k.

I have this kit sitting next to me. I'll add to this thread once its on here in a week or 2, just waiting for some other parts to ship.


Quality on everything looks great though, Im pleasantly surprised with it.

[PyR0NiAk]

Nice first post.. to NICO

[CRyan]

Nice first post.. to NICO

you would use that rainbow flavored welcome sign!

Nice review, but I will have to agree with Pyro, not reaching 10 psi until 6k is out of this world. I mean. Is there ANY turbo that takes that long to make it to 10psi?! Something has to be up with that tune. . .or as already covered, that wastegate.

[PyR0NiAk]

I JUST discovered that welcome sign 3 days ago. I'd never used it, so I jumped on the chance..

[Blown240sx]

If you think the tune is crap then talk to Enthalpy cause its their tune.

[PyR0NiAk]

If you think the tune is crap then talk to Enthalpy cause its their tune.

if I were you, I would have already been calling them.

[Blown240sx]

Like I said the prebuilt kit is not that way I would have gone. I do all my own tuning and put my own kits together for these very reason.

[stockbee]

I apologize for us not having a video, but I can attest that the car did in fact spool SUPER slow, as I was in the car with Chris and Chris (lol same name wut?)

Nontheless, It is awesome of enjuku to have swapped that out. I can also attest to the oil restrictor being garbage. As for the tune being messed up, I don't know about that, but I guess we'll see. I haven't heard of many Enthalpy tunes being off (too badly).

I can't wait to see what the Garret does on the car. looking forward to it.

Though they aren't known to be off, mistakes can happen . . .Just sayin'.

No exhaust leaky, eh?

[Sugar]

Possibly an issue with the wastegate actuator itself?

Like I said, i'll chime in once my kit is on. I am just waiting on turbo lines. Honestly a largest reason I bought the kit was to do a quick review on it and put all of this ISIS talk to rest. That and the s15 turbo's are on back order

It could be but I couldnt tell ya for sure since its my friends car and I havnt see him in a few days since we put it on. His GT28RS comes in sometime soon. Possibly even today. When we get the ISIS turbo off Ill check the gate for play but Im pretty positive I did before we put it on and we tightened it down some thinking that is was loose and there was no change.

[Blown240sx]

We took off the ISIS turbo yesterday and got the GT28RS installed and the thing hauls now. Full boost of 18 psi by 4k rpms.

So it def wasnt tune and it was the waste gate because we check the tension off the car and the gate doesnt move. Im waiting to see if others have similar results.

[PyR0NiAk]

I would think the 28 would spool by 3k, so the tune still may be a little rich. The GT turbo will def spool faster being a ball bearing turbo though. Either way, I'm glad he's enjoying his SR.

[DLYNNW]

i was thinkinng of buying this setup but think im going to take my chance on the mexican garrett an build my own kit. has anyone tried the isis intake manifold and intercooler pipe kit anything good about it?

[Sugar]

UPDATES!!!


***

Fitment is obviously an issue with this kit. I have Megan Racing motor mounts and the turbo hits them pretty badly, I won't be cutting them thats for sure. I plan on calling enjuku tomorrow and seeing if I can swap this turbo out for the 3360 as I would like to give there turbo's a try.

My car was previously automatic as the first guy had stated and it is a very tight fit with the brake master cylinder. Removing the water neck was necessary to get the manifold in.

Also recieved some nuts with the turbo that were not tapped haha. Not a huge issue but kind of annoying.

So like I said, I will be calling enjuku and informing them of the fitment issue. See if I can possibly swap out for the 3360 as I am looking forward to trying one of there turbos. Still waiting on turbo lines and the OEM turbo gaskets.

[PyR0NiAk]

I've always heard of issues with Auto BMCs, but the motor mount thing is definitely a HUGE deal... I'm assuming this is because of the manifold?

[Sugar]

I am guessing so, I didn't try putting it on the stock manifold though. And I probably wont. The bracket that holds the wastegate hits, it could be trimmed to fit I think. Although the turbo itself won't clear either. I'd say a 2" x 2" corner piece would need taken off the motor mount for this it to fit. I think they are closed today, but hopefully I can get something worked out. I'd really like to stick with there turbo's. i'll see how the 3360 compares physically, hopefully it will fit.

[Blown240sx]

Told ya it hits the motor mounts

I wish you had gotten it in so you could see the spool time. The manifold isnt the issue. The turbo they send is about the size of a GT3076 which is why its so close. The flange locations are the same as the Megan Racing Manifolds.

GT28RS blowing tires off in first and second by just matting the gas.

[PyR0NiAk]

Hm.. My 3071 is not much different than a 3076 and the only issue I had was I installed everything onto the manifold before I installed the manifold. The only thing that comes to mind here, is manifold design and how you clocked your turbos. I'm leaning more toward the turbo clocking considering my friend is running the isis mani with his 2876

[Sugar]

Okay. I got to the garage today, wide band is in and I managed to fit the turbo.

The turbo did hit the motor mounts but not to the extent of which I had first thought. I gave the motor mount a little whack with a hammer, although it didn't do much. The holes in the manifold on the other hand were a bit off which was the main issue, just required a little more force than normal. So I will be running the 3876, Im still waiting on the turbo lines and it will be good to go.
Pictures are just with my phone.




Wont be much longer.

Should also mention that I am testing this as a t25 replacement. So this will be a stock SR, stock ecu/injectors.
