This weekend i came across a deal that seems almost too good to be true.. a local mechanic and his son have a twin turbo 300zx... they are upgrading turbo's and were wanting to slap on one of the used turbo's on my car... he says he see's my car all the time and would like to fabricate a system up and put on the car for like $2,000 bucks!! is this possible? i guess what i need to know is without building internals what is the safest psi to run? and how much strain will be put on my transmission with a turbo vs. a supercharger??

 

do it and worry about the price later.

 

wow, $2000? My manifold alone was about $2000. If you still have a warranty on your transmission...then just got the supercharger because I'm sure your warranty will be voided no matter what with the turbo, then again..could be wrong...what turbos do the 300zx have? That crap might not even get your 300whp.

 

i'm not sure.. i think he said he had t4/t5 turbo's?? not exactly sure... i'm thinking he isn't sure what kinda of work he is in for when he told me 2000... but i'm hoping he will come through... going to talk to him later this week and work out the final price...

 

good luck. I wouldn't do it but hopefully it will work out for you

 

talked to the guy earlier and he quoted 2500 final price for him to do up a turbo system! i'm going to have him see what he can do about the transmission too.. i'll keep you guys updated on the how and when

 

i don't know maaaaaan. good luck to you if decide on going through with it.

 

Good luck...don't think I would be happy with it personally. I really don't think it will give you that much power and you will want to upgrade ..but that's just my thought.


good luck

 

A single turbo off a 300ZX will be incredibly WAY too small for your 3.2L engine, it will choke at probably 5000rpm+ and you will be very unhappy. I would start with the proper sized turbo, then work on all the other parts you'll need to get it to run properly. I can't imagine a decent turbo system costing less than $4k, unless he is giving you stuff for free. Don't forget you'll need fuel and engine management and a good wastegate. Oh to answer your question, I hit right about 7psi max on an all stock engine. 5-6psi is a safe 'reliable' number to run.

 

Do that shit Raekwon!! Sup man,, Been out of the loop for awhile.. Decided on getting a brand new TL instead of an 03 cl.. Still goin with the 6mt though.. Gotta hook up some forced induction myself!!

 

yeah i'm probably going to do it.. they had this 300zx dynoing at 512whp the other day, and decided it wasn't enough! they want 650.. they have just bought new turbo's and sent the block to R&R speed shop to bore it out... its going to be a sweet ride.... however, he is telling me he can get me atleast 102 whp out of the deal...

 

102whp? at what psi? I don't know...I really think those turbos are going to die out prior to redline

 

If he can guarantee his work I would do it. I would hate for him to install the turbos and then something goes wrong and you're stuck w/o an engine and Acura will definately not warranty that. If he is as good as he says , buy that J35 block off the black market and work with that.

 

wow that's a little hard to believe for that price. Are you sure he knows what he's doing? It's going to be a tight fit regardless. Let us all know how it goes. I will be shocked if he can make a little more than a comptech supercharger without the lag.

 

HAHAHA... I'm debating if I should just flame away or actually be constructive.

You are going to need a custom made manifold. You are going to need an intercooler, custom made intake plumbing, fuel management, engine management, a wastegate, blow-off valve, etc.

The engine management and fuel management will be close to $800 alone. Add a good wastegate $300, add the intercooler $800, blow-off valve $300. So you are at $2,200 at the bare minimum already before you even start with custom fabricated parts like the manifold and the intake plumbing. Start with a set of used Comptech headers add another $600 for parts there. Add another $300 for the plumbing parts alone.

Looks like you are over $3,000 even before labor.

... oh and I forgot... I didn't even add in the cost of the turbo

$2,000? Good luck!

 

MrSteve on point again, he's telling you right

 

I can't see this job costing 2k. Unless you mechanic is lubing up your asshole, you should step back take a look at the situation, then come back to reality.

And if you do get a turbo, you may want to consider a new set of brakes.

 

Yep!

 

he has an intercooler, the turbo, and blow off valve.. i already have a set of headers.... he is wanting to hook my car up basically... he lives down the street from my girlfriend and is friends with her family... he is practically just doing me a HUGE favor...

 

like i said.. i don't know about the price either seems too good to be true!? he will back his work i already asked that... i just don't think he knows what he is going to be getting himself into! i know he can build anything.. he's built several nissan's one is putting like 650 to the ground! but that doesn't mean he know's honda/acura! i have my doubts too!

 

Do you know if the intercooler will even fit? The fuel management, engine management, and custom fabrication will consist of the bulk of the cost of installing the kit. It's not nearly as easy to do this to a CL as it is to the Z. A custom manifold will run you close to $1,000 in labor if you want it done right. Plus you'll need intake plumbing for the intercooler.

$2,500 is a joke of a price for a turbo set-up on these cars. Sorry dude.

 

He doesn't know anything about tuning this car. All $2,500 is going to get you is a junk turbo setup built with mild-steel, sloppy welds, and a blown motor because he doesn't know what he's doing.

Has he even discussed fuel/engine management?

 

Wish you luck with whatever direction you decide regarding this

 

Would GReddy E-Manage be good enough for a turbo kit like this? Or E-Manage Ultimate?

 

E-manage is fine. All you need is control over ignition timing and pulse-width.


Honestly... I don't see how it is physically possible to build a turbo kit for $2,500 in parts alone. Even using a cheap turbo. Not only is this guy gonna have to do all the work for free he is going to have to give you some parts for free as well.

 

GL with whatever you decide.

 

even if he is doing you a huge favor, I would want to pay someone who is doing such a serious project on my car.

 

i talked to him more a little while ago and he explained to me why he is wanting to do this more... he has turbo, intercooler, wastegate, duct work, and blow off valve already... he is going to make sure he puts a larger fuel pressure regulator on it... seems like i'm going to have to provide something to tune it with or boost controller... however.. he is doing it because he wants to start up more peformance customers... he wants to do my car and get it out there so maybe people will come see him and he can get a lot more business for performance instead of the usual.. he knows what he is doing, and he has turbo'd other cars he has owned... and none have f'd up... so right now i'm leaning towards him doing it... maybe i'm getting lucky, or maybe its going to be the worst thing i've done... don't know

 

How on earth does he have the 'duct work' which I'm guessing is the intake plumbing ready? Have you mounted the turbo yet? Intercooler? Moved the battery to the trunk yet? If you haven't how has he bent the intake plumbing? How does he plan on making a manifold for you? Do you have the proper wastegate spring? Do you know what is required for fuel management?

If this happens it is gonna be ugly...

 

look man ....

Check out these pics and show them too him ...its not that easy($2500 job) especially for all those parts ...unless the labor is dirt cheap and he's not charging you for the parts you are using ...and to get good power off those little twin turbos...can I only imagine what psi you would have to run ..you won't be running 6psi like the rest of us with over 300whp ...anyway, here are some pics of what he may be getting into ......

Sorry Titan, I didn't have any pics of your setup when I was getting my car worked originally.

Here is my engine bay






Here's Speedr73's car(he's on this forum also)

Thinjim's setup



This is a turbo v6 accord from another forum that I'm a member of. He modified the stock header. I think it looks terrible however it worked but he used a small t3/t4 turbo and was driving around not even tuned.



Just a random pic of another accord v6 turbo that used a t3/t4 turbo ..made 270whp @ 7.5psi along with having a terrible manifold construction(nice welds, etc) however turbo was really only feeding off 3 of the cylinders.

 

duct work? I'm guessing the intercooler piping like Steve mentioned however if so, I hope this is a temp basis as I don't know how good that would hold up. Speedr73 just did that recently while he was getting his intercooler pipes made and said it was night and day when he got his new aluminum pipes done. I believe he used pcv pipe ..but never the less, I would use aluminum pipes for the intercooler piping and stainless steel for the manifold itself.

after

 

i'm not concerned about the price.. b/c he is practically giving me all the parts and labor... he isn't trying to make much money off this project.. he is hoping to gain business after people see the car done.. he knows its not going to be easy, and he knows there is a lot of custom work that will be going into this project... thanks for the input, b/c i want to make sure i know what is going on if i let him take on this project!

 

Let's get back to the turbo choice, because it has the most GIGANTIC impact on the system. Your first post indicates he has 300ZX turbo(s) that he is going to use. While this would be fine if it were a twin-turbo setup, since you will not be able to fit both into a CL engine compartment, you will have the WRONG SIZE TURBO for your engine. The result will be overspeeding the turbo and blowing it up. Or, if you wastegate 90% of the flow over 5500 rpm the engine will completely run out of breath. Take a good look at what kind of turbo it is, do not overlook this. We redesigned a turbo system and made 70+whp more at the SAME boost level because the turbo was properly sized.......

 

Maybe I am biased but blk2001tlon19s's and speedr73's car have inherent design problems:

1. blk2001tlon19's: The exhaust piping is run above the tranny, in-between the radiator hoses and all the electrical connectors. Yes, its covered in wrap, but there are way too many bends on the manifold. I bet if you remove the wraps you will see several 'hot-spots'. Also, the front and rear manifolds arn't of the same length so you are going to see 'pulsing' effects.

2. speedr73's: The downpipe goes 'under' the tranny - what kind of ground clearance does that have?

Blue's and Thinjim's are the same kit and as Blue said, turbo choice is very critical in design. I will bet my hat that no other kit can make 460-470whp at 10psi as proven with our design.

 

Ok? My manifold is fine. I haven't had any problems with it. Thanks for your insite even though it wasn't requested. My setup works great and enjoy it. Have a nice one. Design problems ...love it when the pros talk.

Your design is the best and I'm sure no other kit will make 460-470whp @ 10psi ...good point, I agree with you 100%!! When I try 10psi, I'm hoping for 350whp so I will only be about 110hp behind so that won't be that bad since I have a tl-p

 

Back to the turbo size. I think he may have said it's a t28? Is that too small?? If they can do all the stuff they promise and not mess anything up it will be incredible deal. I've just read a lot of stories from the guys on here, and it just doesn't seem possible!!! I appreciate all the feedback, b/c my original plan was just to order the comptech supercharger around the end of june and install that with one of my buddies that works for honda...

 

I say ....if you can get a manifold like allmotors' design(the best one out there) then get it....otherwise, get the supercharger.

I believe T28 is a pretty small turbo and is normally used on 4 cylinders.

 

Don't take it personally... its my opinion. Nobody said you arn't having fun with your kit or that it doesn't work. I just don't think it is optimal... that's all! Even
Blue's and my old kit (ThinJim's) isn't optimal. MtBkr's is even better. My first kit sucked - 345whp at 6psi. I didn't cry about it... we made a better one.

Now you can see why I don't like posting on this forum anymore.

 

We're actually going to be testing that out very soon, when my pipes come in. I'm pretty low, about 2.25" drop, and we're going to go lower on mine to test out how the pipes do for clearance.

 

word allmotor. no reason for him to get his panties twisted. what you said is a fact. he just doesnt wanna hear it.
