Rear mount nytro questions

[tylerearl88]

I have an 08 nytro that I am currently in the process of building. I building the kit from scratch and have a hole bunch of questions. I know its alot of work and I know what I am getting into so don't bother trying to tell me to just buy a kit. I am using a mitsubishi 16t turbo and installing a head shim and doing the valve timing. I am running a stand alone fuel injection system. Also I am at sea level and would like to run 10lbs of boost on pump gas.

My first questions are:

-Will I need a fuel pump or will I be ok for now?
-Will a diaphram pulse pump work as a return pump for the oil from the turbo?
-Is an intercooler need at 10lbs of boost if its rear mount?
-If one is need will a tunnel cooler like in the mcx kits work?
-How hot does the oil get? should I be running a small oil cooler?
-Does anyone have any extra info? Anything would be great?

Thanks.

If your doing a rear mount/midmount,i dont thank an oil cooler will be needed The oil lines will stay cool.At 10 lbs the stock fuel pump should be fine,Ive seen older style turbo kits without intercoolers,but if you could use one like the MCX that would work just fine.As for the oil pump im not sure.

I would like to get around 200-220hp. Is this unrealistic with the setup I am using. Will I be able to achive this without an intercooler. I do not ride in the mountains or much deep powder so there would not be as much snow hitting the turbo as there would be on a sled doing so. Should I be using the coolant side of the turbo for that reason?

Anyone have any info? Any help would be greatly appreciated.

Thanks.

Realistically you are looking at building more of a low boost kit. You dont want to hear this but buying a low boost kit you would have a kit that fits and has all of the RD done. Think what it will cost if you have to fly it out or blow a motor. Getting the fuel mapping correct is not as easy as some may think. You could spend the whole season trying to get the fuel map worked out and clutching to match. For 3k you could have a system that works and hopefully less headaches. You could still install it yourself and save that fee but trying to make a kit has several headaches.

7-8 lbs would be more attainable anything higher you will need an intercooler.

-stock pump is fine up to 12ish lbs
-mcx is a mechanical pump, PL uses an electric pump (does not work that great, some success at mounting it near the turbo)
-10lbs is pushing the limit for a intercooler
-The turbo gets crazy hot but I dont think any kits run a oil cooler.

180 maybe.

what does coolant side of the turbo mean?

In our experiences you would need the fuel pump, i don't remember the specs of the stock fuel pump but I beleive it can't flow consistently high volumes while under high boost.

We've used a diaphram fuel pump for the turbos, but it needs to be mounted in the rear near the turbo as it can't draw through long distances. Usually if mounted wrong you will get oil in your charge tube. also make sure the electrical is properly protected from pinching and heat..

Rear mount do benefit from the intercooler , but it is best if you can incorporarte a primary intercooler like MCX under the tunnel as it gets snow and is quite effective. remember rocks will hit it so use thicker aluminum. I've seemn holes in the MCX intercooler.

For a engine management system you might have good luck with the SDS system Neil (NM on here) is selling..

mcx kit runs to 15lbs on stock pump and if you want to run 17lbs you need the external. Fuel pump should be fine.

Some of the early kits came with an external but now only an external for the 17lb kit.

I have neils sds system and I will be making an intercooler like the mcx one. I am using the same turbo in the same location as the mcx kit so I figured I could use a similar clutch setup to start with. As for the fuel it seams like Neil will be able to help me get the initial setup and I have an air fuel gauge to help me fine toon it. I am putting a head shim in and doing the valve timing so I hope I will be able to run 10lbs of boost. I was figuring it would be about 200-220hp because a 180 hp kit only runs 6 lbs. If I end up needing a fuel pump I will install one. I have never seen a kit that included shim cam jig clutching and gauges for 3000$ but I figure I will have less in this kit even with the rail extensions and avid cogs included. Thanks for all your advice and keep it coming please. Please let me know if I am wrong with any of my thinking too.*

Thanks.

I would also like to know how the mcx pre cooler in the tunnel is designed? Is it just square aluminum tubing with ribbing on the one side?

I think you will be alright without an intercooler as MCX's 180 hp kit uses a 16t turbo at 8 lbs boost. The larger 19t turbo will be more efficient and build slightly less heat that the 16t at 10 lbs. For a low boost set up a 19t is probably a little over kill but if thats what you have in hand it will do the job.
