3TGTE Boost - How much can it handle??
|

I have a 3TGTE, the turbo on it is gay. Its got problems, I just pulled the motor out and ripped it off and I also have a T28 out of an S14 Siliva.
I am wondering how much boost a good condition CT20 can give out?? and depending on that I might buy another or have mine reco-ed rather than fitting the T28??
Also does any one know how many RWkWs the stock injectors are good for?? and if they are no good for 150RWkWs then does any one have any that are and that will fit it??

If your target is 150rwkw, do yourself a favour and fit the T28. The CT20 won't do it in a screaming fit 
Stock injectors are 295cc. 7MGTE injectors make for a good upgrade.

The injectors will fit the rail perfectly, not sure if the injector plugs are exactly the same though, but thats an easy fix.
I can't say for sure how much power you could potentially make before the stock injectors run out of duty cycle, as I never pushed them that hard before upgrading. Depends on your rail pressure also.

also the stock 13B turbo injectors are a straight fit. i also would like to know what the max PSI of the stockie turbo is? not the absolute so that it blows in first gear but max drieable PSI. i know they are 7 stock but whats the best it can do?

I would have to say that the poor turbo would explode itself running 30psi, let alone everything else...

thats brilliant!! One of my brothers has a 13B turbo and its got upgraded injectors, his old ones will defiantely be lying around
to 20vturbo, first nissan Z18 ecu, what car does that come from, and did he have it reprogrammed?? if so do, you know who by?? Also I assume that your friend wasnt running the stock turbo, what turbo did he have?? and did he have internal upgrades??

A stock 3T GTE puts out 160hp, the limit of stock injectors is around 200hp. The CT20 is good up to about 12psi, over that and its making too much heat.
I currently have a GT25 (320hp) running 14psi on stock pistons without any trouble. getting 145kw at the wheels. My ijectors are 440cc. I think the 13B ones are 550cc.
The stock ECU is also good to around 200hp, but tuning is limited and you are better with an aftermarket system.
My mate has a high flowed CT20 running at 18psi and getting 135rwkw, thats the best result I know of from a stock turbo.
I'm going to increase boost again shortly to test teh stock pistons to the limit, I reckon they are good up to 18psi and then tuning needs to be spot on or else they will fail most likely on the landing ring.
Cheers,
Simon

good idea!! wind that boostup ....dont be weak!!
145RWkWs sounds pretty good, I'm hoping for more but Id love to know how much the stock internals can take before they melt. The turbo I'm putting on should be good for 18psi so i should have enough to push the internals pretty hard
Let us know how your boosting goes...
