Enjuku/ISIS Turbo kit w/ 3876 turbo

[Blown240sx]

It didnt hit much on our either but it still required modding equipment which unless stated shouldnt be part of a bolt in kit. A 1/2 movement of the turbo flange would have given enough space for the turbo.

Let us know how it spools.

[Sugar]

What style flange is the oil drain on the ISIS turbo? Is it similar to a T3/T4 drain flange? I was hoping to order one tonight.

[Blown240sx]

Its just your standard 2 bolt drain. Its slightly larger than a T25 drain. It looks like it would fit a T3/T4 turbo.

UPDATE::::


Well as of now everything done. I was planning on driving the car this weekend, and having it ready for an event next weekend. But... nothing fits at all.

Main issue is the turbo is to big to be bottom mount. I had to cut the 90 degree coupler off the turbo because it was hitting the strut tower, it still hits but I managed to squeeze it in there. This made the cold pipe fitment odd but I worked around it. The only reason I can't get the car done is because of the suction kit, and the suction kit is . It's pipe shaped like an S, honestly there really isn't a way to use it. Luckily my friend is very good at fabricating, we are going to make new intercooler piping and a suction pipe of some kind.

Initially I was very pissed, I wanted to call enjuku about giving me $100.

Cone Air Filter Kit $69.99. I recieved a filter, no adapter
ISIS Aluminum Intake Pipe $60.00. This is the S pipe that is useless.
Now I did also get couplers but no couplers which fit from the turbo to the Intake pipe, I did have one to use but as I said there is no way to use this pipe anyway. You can make it fit on the turbo but if you are running a draw threw setup the maf will put your filter well past your radiator.

Needless to say im pissed. I need to tow my car to my friends house for him to do my piping. This may be a couple weeks since he is busy as well. So I will be missing 2 events most likely and spending an extra 100$ to make some piping.

I'll be sure to update with how the turbo itself is, but as far as the "kit" goes. You are better off getting the turbo and manifold and getting the rest elsewhere. I lied, the ISIS turbo lines are pretty nice, I didn't have any issues there.


Recap:

Turbo lines: Fit good, no issues.
Turbo: Looks nice, haven't run it though.
Manifold: Looks nice, feels nice, fitment is so so.

Everything else is garbage.

The isis intake pipe is the worst thing I've received from ISIS to be honest. We cut the end off one of mine, but still had to unbolt the retaining bracket for the dipstick... That intake pipe is designed for the T25 and T28s only it seems, and not if you have power steering.. Everything else I've gotten from ISIS has been pretty awesome.

[Sugar]

This is me.


I managed to fab up some gawdy intake pipe to get it running. I primed the turbo and fired it up. Let it idle a bit while bleeding the coolant and I noticed a oil leak...

The inlet on top of the turbo was leaking, Instead of taking all that s*** off I just cut a box end wrench to get in there and tighten it. Well it never really got tight, it started getting tighter, but nothing like it should. And then it stripped...

Needless to say I am very pissed. I'm pretty sure it's due to the oil restrictor in the turbo. I'll be calling enjuku tomorrow, after some of the issues I've had with fitment and that stupid suction kit I am hoping they will send me a new oil inlet free. Also going to talk to them about running it without the oil restrictor since Im sure thats the issue.

Soo everything is coming apart tomorrow. Ordering some piping soon to make a intake pipe and new IC piping. Here soon i'll have an actual useful update with better than cell phone quality pictures. Maybe I can even get some video of my car on a track...

[PyR0NiAk]

I don't think tightness was your issue. The oil feed line bottoms out on Garret turbos as well... Sounds to me like you had it cross-threaded.

[Blown240sx]

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).

Think I was exaggerating when I posted my review now Pyro?

He didnt cross thread it. The resrictor fitting in the turbo is the issue. Also that oil fitting they send isnt what your "supposed" to use according to Enjuku. They told us the banjo fitting was for the feed of the turbo. Only problem is they DONT send a bango bolt to go with the fitting..... Why include a oil feed fitting that your not supposed to use.....

Hey Sugar take the oil fitting out and use a flat head to screw out the restrictor then go to a hydraulic store and get a new fitting with a 3 an inter diameter. That will be more than enough restriction for the oil.

Get ready for a s*** spool.

Yeah I went ahead and ordered a new fitting. http://www.frsport.com/Turbo-Oil-Inlet- ... 14985.html Im going to call enjuku and see what they say about it as well.

They will give you the same BS they gave us. "we never had these issues on our cars" and a bunch of other run around. Just be firm about it and get s*** done. We got them to take back their crappy turbo and get a GT28RS for the difference in price.
If you follow this path make sure you get the required wastegate and couplers for that turbo. We had to scavenge parts off my old blown turbo box to make it fit properly.

[Sugar]

I'm still thinking the turbo will spool before 6k, thats unheard of. Cummings Diesel turbo would spool faster than that on my car you know... but if I do end up getting rid of it I'll be going back to a T25 for now. I just bought this kit to review it and try to get my car ready fast for some events. So much for that.

[Enjuku Racing]

If anyone ever has an issue please, just contact us and we can help you through it, some how.

I am going to try to address some of these issues you guys had.

Oil Inlet fitting - with the turbo there should be a banjo bolt and banjo fitting that needs to be used, and not the fitting that comes with the turbo lines. (We ship the Turbo lines in the original packaging, the original turbo lines are designed for a stock T2 turbo and not these aftermarket ones, this is what the other fittings "should" be in with the turbo)

Intake kit - The intake kits are originally designed for an S13 SR stock T25 turbo. On the smaller 3360 turbos they work perfect with the correct coupler. With the Larger 3876 turbos there isnt the same room under there and they need to be trimmed, but do work.

turbo size - The 3876 is a huge turbo for a bottom mount, it was designed for the guy that wanted bigger power on a smaller budget. It does work and can fit under there. As with 99% of aftermarket parts, you need to have good knowledge to be able to make what "you want" work.

ISIS is actually working on a copy of the GT2871R in size (just not ball bearing) Should be priced the same as the others and will just be like doing an install on those. (need a coupler for the front of the turbo and make an intake pipe - we just try to make it easier by including one that can work with the turbo)

We do our best to assemble these kits for people who dont want to go searching for a ton of different pieces.

When installing an aftermarket part - if something doesnt feel right or seem correct, ask someone before doing. (maybe a fitting was miss packaged, or a part was miss labeled, or maybe that is just how it is)

I Personally installed this kit with a 3360 and worked great, and the car is still running over a year later. One of the other guys here just installed the 3876 on his KA and it works very well, just a large turbo for bottom mount.

If you are unhappy with something give us a call and we will do whatever we can to help get you what you want. Just know when dealing with aftermarket performance parts and cars, nothing is like OEM. I have been doing this for over 10 years now and have installed numerous kits on cars. There are some big name brands out there with instructions that still require modifications. It part of the game we all play - called cars.

We sell the ISIS parts because they are inexpensive and very good quality for the money.

Feel free to give us a call or shoot me an email directly if you ever have any issues. - [email protected]

It's nice to see you guys still in the "online community. I will be doing a "formal" review after I have it running, which should be tomorrow. Nothing but good things to say about enjuku as a company.

Any comments on the late spooling? I've run into some issues, but as you said they were minor and I worked around them, but I would expect this turbo to spool no later than 4k...

[Enjuku Racing]

It is hard to keep up with all the millions of forums out there, but we are still around as much as we can. :o)

As for the late spooling, I honestly dont know because i dont have the car infront of me. The guy here who has the 3876 on his KA makes about 10psi around 3200rpm, but doesnt have his tune set right yet. It will spool later than a true GT series as it isnt ball bearing, but shouldnt be 6K or anywhere near that. I think there may have been in issue with the wastegate, either is was bad, or if the turbo was clocked at all it might have messed with the WG some how. Its hard to tell without that specific car here.

Let me know if you have any other questions or issues and we will take care of you anyway we can.

thanks
Ken

i've been keeping a close eye on this thread and its awesome to see that ken will come in the forum and defend the products he sells with such conviction.

[PyR0NiAk]

This is exactly why I always tell people to contact Ken.

The turbo that you all sent in the kit was clocked the way when you sent it. We didnt change the position because the owner who I helped install the kit told me you all said it was clocked where it needed to be.
I checked the gate before I installed the turbo to ensure it was tight enough. We even adjusted the gate to make it tighter while it was on the car.

Im not saying its anyones fault or how all the turbos will spool but this is how ours reacted. The GT28RS thats on there now spolls 18 psi before 4500 rpms and straight destroys the 275 tires on the car. Ive never had good luck from non name brand turbos so thats why I tend to recommend the name brands for that situation.

Ken BIG suggestion. Ask someone or even you all need to make a install write up for things to do before you try to stuff this turbo down in the tight space. Also get rid of the plastic braided water lines, I have a local hydrolic shop that makes me stainless braided lines with automitive aluminum fittings for 30 bucks for the pair. Im sure you all can get a killer deal on something along those lines.

Lastly the turbo kit DID come with the banjo fitting but NO banjo bolt, and the factory banjo bolt does not work.

[Enjuku Racing]

There must have been something just weird with that specifc turbo and/or wastegate.. but I think everyone ended up happy and we got him all taken care of.

I am a little confused about what you mean by plastic water lines? The ISIS Turbo lins utilize goodridge black hose. I was unaware of any plastic on the lines at all. What brand was sent with your kit? I know some people we had to switch to Circuit Sports lines (but i dont think there is any plastic on those either) because the black ISIS ones were back ordered. If you can give me a call or shoot me an email directly so i can figure out what part we are talking about

Agreed - to an extent on your suggestion. We do our best to test or have tested every ISIS product because we dont want to sell crap. However it is virtually impossible to test every combination of the millions of parts we sell. The ISIS turbo kits were assembled by me and the guys at the shop utilizing parts we know will work, or can easliy be made to work. We dont have a huge R&D like greddy to be able to put all the kits on every setup and have detailed instructions, unfortuantely the cost of the "kits" would double. We do the best we can with what we have. If anyone has a problem just get with me and i will take care of it... no biggie

thanks

The water/oil lines I received were very nice, I liked especially liked the black.

I got the turbo back on the other day and...

I drove it around the block and it doesn't want to spool. It feels like there is a 2 or 3 lb spring in the wastegate, once it builds any pressure it just lets go. It is also still leaking from the oil inlet on the turbo, I ran the oil line the other way, with the banjo bolt in the turbo like I was told. Used the supplied crush washers and torqued it to 18 ft/lbs, I did managed to tighten it more after we saw it was still leaking and it didn't do a thing...

I'll be calling tomorrow.

[Sugar]

Talked with Ken today. There are some negatives in this thread but if anybody is following it, I wouldn't hesitate to buy there turbos. He is sending me a new turbo out to see if it solves the wastegate issue, as well as sending me a different model basically because I wanted a smaller one, so I'll be receiving a model between the 3360 and the 3876 in size.

The r3876 was hitting 10lbs before 4k though. The turbo would hit 10psi then drop to 0 and not build boost until I got off throttle. The turbo did begin to spin the tires, felt like it was going to pull good. Only reason I requested the smaller version was because of how close the turbo was to the strut tower.

Anyway, really appreciate them not hanging me out to dry.

[PyR0NiAk]

Ken will NEVER hang anyone out to dry... Most of the stuff in my engine bay came from them..

[Enjuku Racing]

Update from our end. We did receive another customers 3876 back because he was complaining about it not boosting properly either. Which was baffling us because the one on the car her is boosting fine. It seems that because the large housing size the turbo needs to be clocked differently to clear the strut tower and get a coupler on there. When doing this is changes the angle of the actuator arm and it can get stuck on the bracket. There is a very fine line with the clocking and this actuator arm. I actually looked at one in the box today and it wasnt clocked right out of the box. It can work, but can be a big pain it seems like. We are trying to figure out the best solution. The turbo itself is good and will make good power and can work, as it works on our car. Just not that easy because of the size.

ISIS has a GT2871R turbo that is non ball bearing and has the same specs as the 2871R. So clearance and actuators getting twisted shouldnt be a problem.

If anyone has any other issues, just get with me and we will take care of you.

thanks
Ken

[Blown240sx]

Ken By plastic Im speaking of the braiding around the hoses is plastic and doesnt deal with heat to well. Ours actually started to melt cause it was to close to the manifold. We pushed the hose way down now but I just think the stainless braided would be a better option around that heat. Maybe not for short term but for long term.

[redcoupe90]

I started a thred a while back called isis this isis that...and it was about the quilty or the 3360...i love this turbo...some reason my turbo seized and ken replaced it no questions asked....i deff goona get the 2871 vers ....for 500 how can u go wroung?.... thanks ken. Keep upvthe good work....
