I am certainly interested pending details; single or twin, intercooled, bolt on or custom, injectors, pcm upgrade, price range? I am considering another Q to relpace my mustang track slut.

I don't have a Q, but I want one eventually. I have always thought it would be insanely hot to have a nicely done twin turbo'd Q. I'm with statichead, I want some details on this kit.

Welcome to NICO.

Maybe its just me, but for a first post, this seems a little fishy to me.

No details as to what you have in mind as far as a "turbo kit" goes, and no real details in your sig or profile.

Smells a little too much like bull$hit to me.

Welcome to NICO... certainly you may find some interest in a turbo set up here. 50 people? I doubt it.

In any case...you'll need to do a few things before getting that type of group-buy organized.

A. Post a lot of details as to how you plan to get past all of the pitfalls that have caused trouble with this project in the past.B. Pricing and details about system?C. Introduce yourself and give some background...we'd love to get to know you and know how you developed the turbo system.

I would be very much interested, but a turbocharger wouldn't necessarily help the low-end torque problem that the q45 has, but then again thats just my 2 cents.

In his defense, he didnt say all 50 had to be from NICO. Sounds like he's try to shop an idea around various forums.

But please, give some details on what youre planning!

That's true. And certainly not 50 who would want to go for a rebuild to add lower compression forged pistons, relocate battery, mount twin intercoolers, rediesigned intake plenum and filter box, oil cooler, higher capacity oil pump, etc.

Wonder fi it is a one time post?

except.. you dont have to have forged low comp pistons, new plenum, or a higher flow oil pump unless you want like more than 600HP!

WHy would you run 2 sidemounts? That doesnt make any sense when you could run a big front mount.... I SUPPOSE you could run the sidemounts in the wheel wells but you wont get a big enough one to not have them heatsoaked after one run... Then you think about doing water to air, and thats a mess, there isnt enough room... Plus they dont get really good flow like a front mount would...

People seem to forget a certain someone whos been boosting 400-450HP on a stock Q motor with 150k miels for the last 3 years!

A tremendous difference between 400 HP and 600 HP even 475 HP.

Often 25 HP [or 400 rpm] is the difference between longevity and sudden failure.

I'll bet JWT didn't sell 50 Q ECU or trimode TCU upgrades...........good luck.

I certainly am. Don't know anyone using forced induction on a VH45DE for the street without serious problems, let alone for 150K miles.

almost as good as the $35.00 supercharger in the back of magazines that GAURANTEE's 15 Horsepower and 10% MPG improvement

The easiest way to do a turbo on a Q45 is to use the Squires universal kit, tie the 2 exhasut pipes together after the rear diff, put a K & N filter in the rear, and run a pipe to the MAF. You would have to install an oil pump and possibly increase the injector sizes, then get the romulator kit to re-do the fuel mapping according to the boost. For about $5,000, you could have about 100 to 150 HP more. You might not even have to change the injectors or ECU if you kept the boost low enough.

You would keep the same throttle body, exhaust manifolds, and intake. There are no parts under the hood that would cause heat issues, and the need for an intercooler is reduced, since the exhaust gasses at the rear mufflers are so much cooler. There is a huge improvement in performance of the turbo because of the cooler air temps. If you did add an intercooler, it would be much more efficient. The turbo would be much smaller than one needed right at the exhaust manifolds, also.

Look up STS or squires turbo system. They have done a great set-up for the Corvette LS1. It comes with everything, down to the clamps. I am thinking of installing one on a friends 2007 Corvette with an LS2. The install time for the Corvette kit is 4 to 6 hours! It comes with injectors and the custom programming tool for the computer.

All we would have to create, is the exhaust pipes from the resonators to the turbo, and the pipe from the turbo to the MAF. The rest is in the universal kit. If your were really good, you could piece the kit together without the help of Squires. I bet a system for a Mustang 4.9 or 4.6 would be about the right size. You just wouldn't need the program for the Ford computer.

I've done a lot of research on the Squires system and spoke to them many times. It's a great option and nobody can convince me otherwise. My nephew was their "poster boy" for a while with his Hemi truck with one of their first systems on that truck. It was in a bunch of magazines and they even showed it at SEMA. It was incredibly fast.

I'm trying to piece the parts together myself due to budget constraints to make my own rear mount turbo setup. Will probably take a while but I hope to eventually get it done. I've estimated roughly $1000 to piece it together myself plus tuning. Time will tell....

I have always been very intrested in the Remote turbo setup. There is no way I would buy the kit when I could fab one up myself for half the cost though. I just won't do it with 181K on my car either but I will have that setup on a different car someday.

My Q is pretty much my toy. I don't drive it every day. It's got 160K or so on it but when/if I get around to completing the turbo or any other mod for that matter if I blow up the motor.....at least I had fun doing it. I'll just have to rebuild or replace it. The cars been paid off for years and is worth more to keep around and play with. If I were to get another car with lower miles it could blow up too, no way to know. I'd prob. cost less to repair the motor if it blows then to buy a newer/lower mileage car only to have the same risk of damage with performance mods. Plus, everyone's always talking about boosting a Q but nobody's done it. One of these days someone will take the leap and fork over the cash and be immortalized for it.....assuming it works. Well we know it can be done, there have been Q engines installed in other cars, boats, etc. that have turbos, why not in the car it came from.

what I dont understand about you guys is you make it sound like Q motors are expensive!!!! Q motors are like the cheapest motors in the nissan world, VH45s go all day long for 1000 or less...

Who cares if its got 100-150-200k on it.. Boost it and if it blows put in a new one!

There's not much room in the undercarriage to adequately run the intake piping of a rear-mounted turbo back up to the front. It's totally doable, but the second your Q is lowered, you place that piping precariously close to the ground. The depth of the frame rail protrusion from the floor pan is not that great, and there's no raised areas under the crossmember to allow you to tuck that piping up. And if you're really low, you will be guaranteed to bash that intake piping up good. I had already mocked up piping along the chassis of my Q, and deemed it not a good idea... then again my Q is a lot lower than others, but I'm sure the next crop of modified Qs over the next year will be quite low also...

I thought 450TT ran twin turbos on the VH45de motor.

It does. Those are mounted in the similar location as the 300ZXtt turbos.

I noticed that the Corvette kit routes the pipes inside the rocker panels on both sides. I have not tried to get into the Q's rocker panels, but they look like there would be enough room there.

I found 3 people in Texas who do or at least did, but they're not Nico nuts like us and they don't respond to any more of my emails, but they were street drives for two of them. They also had differentials made from NASCAR folkes somewhere, with NASCAR grade metal ring and pinions and so fourth. Anyway that's just an FYI. (ran into them when researching my 4:08 obsession). I think Glen knows them, not sure though.

The pump itself is pretty robust so I would say no on the pump itself.

The oil pump sprocket on the oil pump itself and the dinky little chain it has leave something to be desired.

Added insurance that you always have lubricant going to frictonal surfaces within the motor is never a bad thing though.

I can't believe this thread is still going. Random guy posts 1 time about needing 50 people to buy some turbo kits and you'd think it was the end of the world...

on the plus side... maybe someone will figure out how to turbo the Q.
