sounds gangster:biglaugh:

anyways, ever consider a holset hx35 turbo? they're cheap, spool quickly, they're reliable and are capable of the numbers you are looking for. It would really suck if you bought, lets say, a gt35r, turned up the boost to "18psi" then have stuff blow up because of the only 2 supporting mods that you've mentioned, which is not enough safely. Like everyone else has said, a larger fuel pump and 550's wont cut it. Aside from the 2 mods you've mentioned what other mods do you have?

I do belive that all he asked was what cheap turbo would be good for 400-500whp. Cheap is relative..But assuming 1000 is cheap for a nice turbo.. I have a Garret 60-1 with a .68 hotside and am hoping for a very well rounded setup. I wouldnt get to close to the 500 mark with 550's.

Agreed .

The OP should be well aware of supporting mods needed. His question is not abou that. His turbo is bad and needs a new one that can be utilized in the future to meet his goals without purchasing another one.

Cheapest first
1-Holset hx35/hy35
2-Used brand named turbo in 57mm-63mm turbo
3-Garrett 35r

Search the classifieds and just be patient.

Either way, his questions have been answered. But read closer again, and youll see where he asks if a Walbro and 550's are enought for his goal.

x2, i was just suggesting what i would do if i only wanted 400whp for the price but wut ev

I think what Ian was getting at is the engine is a ticking time bomb with the stock head gasket and head bolts at a higher power level.

The OP never stated what he has done to the engine to be able to handle a higher amount of power.

perhaps so... either one is a grenade. haha.

-Once again NO, your engine may be built to handle 500whp, but you just dont have the supporting mods for this. With out propper supporting mods it will probably blow up before you even hit 18psi.

How will it blow up with out a J-tube? If you don't know, don't answer questions. Because clearly you don't know.

The J-tube will richen the mixture, just the opposite of "blowing up" the engine.

To answer his question, 550's and that massive Walboro is more than enough for 400 rwhp. You do need tuning to get there, as the attempt to point out was made.

Had a friend that was making 487 WHP on RC 550's And two Walbros. He had a boost spike and the injectors maxed quickly and exploded his engine. However he did make that power for a very long time on that setup..There was just no room for error. BTW it was a stock motor exept for ARP's and MLS.

It will richen temporarily until the walbro burns out then it will lean out and blow up..lol

I never said it would blow up without a J-tube.

assume i have an engine fully built, that would probably handle over 700rwhp :naughty:. i just dont have the fuel supporting mods.

RC engineering 550cc, aeromotive frp, and a 255 walbro is the fuel supporting mods that i have right now.

i just dont feel like buying bigger injectors, getting a bigger fuel pump, getting a high flow fuel rail. that's what i meant by being cheap.

So a 60-1 turbo is the biggest i can safely go with 550cc, aeromotive frp, and a 255 walbro.

If it is, then i guess i'm just going to buy the lipp boss jr turbo.

I dont understand how the lipp boss jr is any better then an upgraded 60-1 ct-26. i thought an upgraded 60-1 ct-26 is not reliable because there's too much stress on the shaft.
If the lipp boss jr has the same size housing the as the ct-26 then what makes it better?

 

[enjoi.this]

The lipp boss jr is much tougher then the upgraded ct26. The main thing that makes the CT26 so unreliable is mounting a large wheel on small o.d. shaft. Lipp has built something with a larger shaft and with high quality components.

Boss Jr. ftw over upgraded CT26

CT upgrades don't have a proportional relationship with respect to compressor wheel and shaft dimensions. With thrust loads, these shafts are more likely to "move" or otherwise distort causing premature bearing/seal damage or even catastrophic breakage.

This condition increases exponentially with higher boost pressures. (Purpose of the upgrade.)

A bolt-on turbo upgrades are usually T3 to T4 sized turbos with retrofitted turbine housings for plug and play adaptation to stock 7MGTE exhaust manifolds.

There is no comparison between a CT upgrade to a bolt-on full T4 style CHRA turbo.

where can i buy or a website where i can take a look "T4 sized turbos with retrofitted turbine housings for plug and play adaptation to stock 7MGTE exhaust manifolds"?

Sound Performance still makes them too, I believe. SP61GT's, etc.

 

[teamslow]

ok. this is what i found.
http://www.spracingonline.com/store/SP_61GT_87-92_Supra_Direct_Bolt-On_/3143
it will cost me $2179.00+shipping for polish and coated and oil line kit.
will the inlet fit over the stock afm accordian hose?
will this fit onto my defcon 3" downpipe? i know the old sp61gt's use to come with there own downpipe. it doesn't say it does on that site.

Or i can a 60-1 lipp boss jr. with installation kit for $1620.00 plus shipping?

How much better is the sp61gt? is it worth the extra money over the lipp boss jr?
