True interest in Single Turbo kit for NA DOHC

Unlike many "Hey I can probably build this that and the other thing" threads, I obviously have a working example of an NA running a single kit that only running 12psi has ET'd 11.4 and trapped 131.77MPH. So it's not "In Theory" or any pipe dreams.

Now, obviously, for the street a turbo like SL-T's is out of the question for most. It doesn't spool fast enough, that can be good for launching since FWDs don't want too much power right off the line. But also, the SL-T turbo retails for $2200 :eek:

So, What SINGLE turbo would "Real" buyers be interested in. Something big enough for power small enough for street spoolup. Something affordable.

I could make a complete kit including FMIC and everything, don't know if the stock front crashbar would stay in the car though :eek:

One thing to mention and this is very important. I will not be making them out of SS piping. #1 it would raise the price, #2 I am setup for Mild steel welding and can't afford to get another welding setup. I use pretty thick gauge piping, mandrel bent and aluminized for corrosion. They could be coated to further corrosion resistance. I have had no problems with cracking or rust so far. I would use the stock cast manifolds, thehy are sturdy, their flow is not that bad and they hold in heat, turbos run on heat (expansion) not flow so the more heat you can keep in the exh the better. One good reason for exh wrap!

Please don't reply Yeah, I want a kit, when in reality you would never buy one. Not to be an ass, but SOOO many times builders go through the trouble of making something that so many say they would buy in a second, to find out on release date 95% of the "potential" buyers back out or cry that it isn't $200 shipped. :p This is what has kept me from duplicating my kit so far. But I have recvd SOOO many emails, PMs, and phone calls I thought it was time to give it a shot.

What would the price be for the complete kit? Or does that depend on the turbo you use and you have no clue what the price would be yet? I'd prolly be able to spend around 2k for a kit after i get my grad money from my family, but that wouldn't be until June '05 or so.

I have no real input that would be of use as to what kind of turbo should be used, because I'm not very well acquainted with the world of turbochargers yet.

No prices setup yet. Everyone knows I don't ream people, I am not going to give it away or lose money on it either ;) It's not going to be a complete kit for $300 :p I can also sell it with or without turbo.

If you could put a kit together for relatively cheap (like under 1500 or so) Im sure you will get alot of interest. The way I see it is youve got 2 ways of going about this. 1. You pick a pretty big turbo and have everything you need to support it and the pirce will be pretty high, but you will get a damn fast car out of it. 2. You go with a little smaller turbo and less supporting mods which will give us N/A's some boost, but nothing crazy, and the price will stay low. Im thinking if you go for the 2nd route you will gain more interest. If you put something together for under $1k i know of a few people that would be interested right off the bat.

1500 will get you a turbo (if that)

Maybe a small turbo. I forgot about how chris said FMIC....Okay, throw that 1500 out the window lol

chris, i'd start with PT's 61mm turbo. same thing a lot of the supra guys use. good for upper 500's rwhp at high boost. FAST spooling turbo. i'm talking about 15psi at 3500rpms. that's dr650 territory AFAIK. definately try out the .58AR first, they can be switched EASILY to a bigger one for cheap.

another thing you gotta keep in mind. most of these would be going on a street car so you'd need to redo your exhaust routing to make some accomodations for the catback.

guys, if you're looking for a kit under 3k this would most likely be out of the question. there is a LOT involved in this.
turbo alone would be ~1200
then you got FMIC - 500
wastegate - 400
bov - 300
a LOT of piping - i'd say probably at least 500 bucks worth of material but i'll let chris chime in on that.
and then take in the amount of labor that goes into this.
this is NOT the time to be cheap. so if yall want another turbo kit option don't cheap out.
good luck chris.

SL-T's turbo retails for $2200 :eek:

Using a fiar sized but not SL-T turbo size turbo would be best.
Under $1500 with Turbo and FMIC? Not happening. Not worth my time, and near no profit.

I could base the kit off a certain turbo, and sell it as a kit, buy my precision turbo or find your own ie:used which could save the buyer money.

The FMIC SL-T uses retails (I sell it anyway which is lower than retail) for $440. That coupled with a turbo and part alone you are not going to find a kit for sale for under $1500.

This thread will shed some light though, I wouldn't be upset if this is how much people are expecting, it will give me an idea of wether I should move forward or not.

I would probably leave BOVs out and let buyers find them. Maybe a cheap one?

As for WGs, I would like ot build it using an Internal, it would Drastically cut down on cost and price. Good Ext WGs are bank, and as the SL-T has shown, Internals work just fine.

And yes, I will route the Exh to hook to the stock cat back. No problem there.

It's the "I want to spend $1,000 or under $1500 for a complete kit with FMIC and Turbo" that has kept me from doing this.

I could do a Precisoin SC61 good for 680HP it is a Sport Compact series T3/T4 setup available with .48 or .63 AR and 69 or 76 trim TO4E comp cover 3" inlet 2" outlet

I sell this for $700 so it's not too far out there.

Look the supra has brought some insightful information.

What is with the cheapskates on this board, they need to realise this world isn't out to give them money. If they want something get some cutbacks in life save up money, work a part time job for a couple months.

Thanks for the insight.

even if you leave the BOV out, you'll either have to weld a flange for them or let them do it themselves.
i would let customers have a choice of int/ext wg too.
it ain't happenin under 3k.

Yes, either way the BOV will need a flange Welded on. Maybe I would weld on a Greddy flange like I have. It's a nice BOV.

A few side notes.... Look at dollars vs return. You can buy base/sl in really good condition for under 5 grand, much less if you are patient. Then for 3-4k you add
the turbo kit and lsd, and a few other things and in a roll will walk most anything
on the street. Suspension mods, and it will be good in a dig to.
Are there shift kits available for the auto's??
I may make one just for the hell of it for my son!
Also, it will be insured as a base/sl.... so for the younger guys, the turbo kit will
pay for itself in 2 years in insurance savings as compared to a vr4/rttt

if you came out with a single turbo kit i would probably get it when are you planning on doing this if you do over the winter? so then the kit would not come out until spring? im sure alot of people would be interested after the results of the SL-T running a single turbo (even though its not the same turbo) and hopefully this route would be cheaper than the Rippmods SC
 
#18 · (Edited)
you think the turbo postion will work well for most people?

you think you could come up with some sort of intake pipe to work with the stock maf, that does not hit the hood or the srut tower? I am assuming you will need a larger customer base then the guys willing to go to a standalone EM system.

I also think alot of us NA guys arent looking for crazy horsepwer single turbo kits, i know i would easily pay 1500 for a small simple turbo kit that gave my car a decent power upgrade, but nothing really crazy. I know you wont profit from it, but i just think thats what all the NA guys want. I just think that people say theyll spend 2-3 grand for the kit now, and then wont buy it later. If it was at all possible i think you would sell the most kits if they were simple and reletivly cheap, i know i would. Something like the xtremeboost kit, maybe with a used turbo/intercooler.

Whats the spool like one those Chris? Would two of em work well on a vr4?

My insurance went down 80/month when i totaled my 95 Base and went to my 92 VR4.

Suggestion on FMIC and crash bar. Cut the crashbar down, to where the bar is just where the absorbers are, and then weld a bracket to hold the FMIC and bolt to the top of the crash bar, MAYBE build a Cheap/Easy crash bar outta mild steel or something that mounts the core to it, and as well still protects most of the front end

That would require no intercooler at all, but using alky/water injection to cool the intake tract (225ml/min nozzle or larger) and a wastegate spring of about 6 lbs. With a cheap 57 or 60 trim T3/T4, that would equal lots of bang for the buck.

Alright, If someone could come up with an actual price for this...I WOULD buy it. I've been saving for this thing, and I plan to do the SL-T conversion this winter. I would love to have basically a bolt on kit...I know thats probably not possible though. If you could come up with something that had like...ALL of the parts needed. And yes, I have the money, and will have it unless something comes up. I've got all kinds of questions about this too, so if you want to sell something to me...send me a pm or aim im:cheesewhiz2099. Thanks!

That is the ONLY downfall with IPO... and not meant as a slam, as I've bought from him, and prices and service are great. But this kit will be complex, and people doing their first turbo install will have questions.
If this gets going, a phone number to reach Chris at is a must.

Just fyi, My FI plans are to make about the same crank HP as a TT model, and never really run the setup past 6psi. I would love to be able to promise you that I would buy your kit, but it seems wheneverf I get to that point something else gets in the way. (Last summer I had enough saved up in my car fund to do the TT conversion and then some, then my tranny let go. grrrrrrrrr) But there is the potential for me to have the cash to get a 2500$ (small turbo kit, or kit with a nice intercooler but no turbo) kit by this summer. I'll hold off on collecting TT parts until more information about this kit developes.

brain fart:
I also always thought it would be uber cool to have a kit with a separate oil resevoir for the turbo, that way you wouldn't have to worry about dropping the oil pan to install. I don't know if there would be enough room for a resevoir thats holds enough oil to allow for aqequate oil cooldown though.

just hope you guys keep in mind that you still need MANY things that chris won't have in his package (and i'm not blaming chris for anything, i think he just assumes you guys would know). you're gonna need injectors which means a fuel controller (this could get tricky with keeping the OEM MAS and a big ass turbo), fuel pump, tuning devices (such as gauges, dataloggers, wb o2s, etc) so it'll be more money than you think even AFTER you buy the kit.
