those are them for now. tell me what you think

[400exrider707]

Who put the turbo in? How long have you run it like this?

[400eXr1d3rZ]

Did you get it on a dyno yet? I want to see the results.

[hondaracer57]

did u buy this bike off ebay or are u the one who was selling it on ebay?

[jdenny400ex]

man what did that turbo come off of? i have heard of puttin tubo's on 400's but i never knew where you can a turbo that small.

[hondaracer57]

from what i read on ebay im pretty sure it came outa a car right?i think it might of been a twin trubo 3000gt or some thing like that...

[blown331]

mroe than likely a TD04 from a 2 litre subaru or so. those turbos are tiny. however its probably much smaller

[flauge]

Yea i remember that. There was a black one on ebay a while back running one of the stock twins off a 3000gt..By what the description said on it, it was running goood.:devil:
Chucky man you got to fill us in on the set-up.. At least on the fuel setup.

[blown331]

Im wondering who modified the carb to accept boost. How much is the carb upgrade? Does someone sell a boost friendly carb for these things? I have a couple small turbos laying around and i'd certainly give this a whirl.

I'd of course rebuild the bottom end with a forged crank, rod,piston and a damn good set of rings

any ideas?

A turbo 400 EX with standard length swingarm?

I don't think having my handle bars pound me into the dirt sounds like any fun.

[Ncboost]

Where is the turbo oil feed line coming from?

[400exrider707]

Did you even buy that quad or did you just jack some pics from ebay? haha

[BigFish]

badass concept, but it looks a lil haggard:ermm:

[2004exrider]

I looked at first and thought that you were still using the restrictive as hell stock muffler but then realized it was modified:p . Pretty cool quad, deffinitely tell us more about it, carb modifications, engine specs, how long its been run with the turbo, etc!!!

it looks like a turbo off a 750seca turbo streetbike i know where i can get one prettycheap i never thoutabout a turbocharged 400 it sounds like fun i might try it next winter

[hondaracer57]

no im pretty sure its off an twin turbo 3000gt..ive seen this bike on ebay...

[chucky797]

yes it is off of a carb. the air box has been custom mane. it is the big silver box that gets the boost feed into it. from there it goes though a hose to the carb. the fuel is using a fuel pressure regulator. it increased the fuel as the boost goes up. just idling it runs 5lbs. it is a td04. i am the one that bought it off of ebay.

and other questions just ask.

ps i am not on here all the time so it might be a little bit before i get back to you

[krt400ex]

that things pretty sweet....how fast is it? wut kinda #'s r u getting out of it?

[hondajoe05]

im thinkin.... 400ex with a turbo.... fast as hell no one would have that ****.... im gonna look up priceing on all this and try it myself

[pimpazzberetta]

A TDO4 is a damn big turbo.. for a quad. I had one as a stock turbo in my Dodge SRT-4.. with came stock @ 230 whp 250 wtq, with a few upgrade it was pushing 297 whp and 330 wtq. Upgraded to a S3 TDO5 370 whp and 375 wtq.

How is the lag on that thing? Geez please get us some video's. I've got a TDO4HR just sitting around.

ya but the fact is its still a neon front wheel drive. hahaha jk man
but ya how much hp the quad have?

[gmccomas412]

yea i'd really like to here the numbers you are getting out of it aswell? and if you ride with other quads and how well they keep up to you and what kind they are?

[blown331]

Looks like I was dead on with my turbo guess :)

Also, just incase you guys aren't aware.

Turbos are a lot less harsh on motors than people think. One thinks "boost" and immediately thinks future problems. I think if someone would design a beefy set of rings for the 400ex and run a CP piston at about 8.5:1 or lower you could have one 400ex that would make mod'd 450's look retarded, and with the proper setup be reliable as can be :)

[ncsmash]

I agree wit blown331 there is a guy in tucson that will make kits for any quad he has made a few turbo 400ex's and he found out that it will be just as reliable as a stock one using a lower comp piston. He did one like the same setup as the black one then he tried mounting the turbo up by the oil tank with the air filter off to the left of the machine by the shifter mostly for dunes because of it being so unprotected. He also told me because of the boost jetting is so critical and the slightest change in elevation could cause an unhealthy 400ex.

i drive a APR tuned stage 2+ turbo VW Jetta and i'd loveee to ride a turbocharged quad.. i could imagine what that'd be like on a motocross track, keep the revs up into the turbo range and haul ****in ***..

are you running any sort of wastegate or blow off on the quad?

looks nice, and def grab a digi camera and get some video's of that thing in action!! i'd love to see/hear it!:eek2:
