Time to Upgrade. Input needed
Re: Time to Upgrade. Input needed
Jeff never adjusted them when I took it to get tuned. Why he didn't do that, I'm not sure, but he didn't.
I know the housing is small but i built the engine so it would be a street beast...that's evidenced by the fact that full boost is reached very early and spool is pretty much on demand.
If he wants to upgrade, a larger trim is necessary, i agree.
Also, ditching the recirculated dump wouldn't be a bad idea. I put that in to keep the car streetable and livable - read: quieter. Ditching that would free up some power.
Other than that, you're looking at a VTEC head. I wouldn't do it. I'd get the larger trimmed turbo and ditch the recirculated dump and see where that gets you. That head doesn't have many miles on it and it's completely rebuilt and upgraded. No need to throw it out.
The head is not ported, however. It was just "refreshed" since the original OEM head had 150k on it.

Re: Time to Upgrade. Input needed
Added meth kit to be able to run higher boost and planning to get retuned next month to see what this turbo can do (it is a .48). Was thinking about getting divorced downpipe but thats pricey.....can I simply cut out whats on there, run a dump tube, and weld up the hole? Or would that affect something else?
Re: Time to Upgrade. Input needed
I would slap a vtec head on there for sure it looks like you have too much money in your setup when stock gsr's make more power on less boost than what your running.
Im sure you could sell your head for more than a stock head so that would be the cheapest upgrade. Then by the bigger turbine housing. Why not run e85?

The more and more I read and ask question to people about the turbo size is that it is definitely a choking point in the setup as it is only a .48 when the smallest stock size is a .63. Thats why I am going to stick with upgrading that part of the setup for now and shoot for getting it to put down 475whp. Then I may do v-tec further down the road if I want more power.
With that said, what size should I upgrade to? The .63 or the .82? And is the only thing I would need to change the turbine housing? OR would more parts of the turbo need upgraded?
Anyone know a good place to order these parts from?

Re: Time to Upgrade. Input needed
Getting rid of recirculated dumptube will help out your power as well....
As far as slapping a VTEC head on because GSR's make more power...blah blah blah....how much of that power can you put on the ground? You're nearing the point of diminishing returns. I'd focus more on getting the power to the ground than adding more and more. Dyno queens are just for bragging rights.
Not to mention, you are getting way more torque than a gsr.

Re: Time to Upgrade. Input needed
Dump is going to be converted to atmospere. And I like my torque. I can stay in fifth gear all day and still make it up decent hills without slowing down.
.63 a/r housing, Comp Clutch Stage 5, and a new tune is what I am doing. Methanol is hooked up so I can run some decent boost on pump.
As far as traction. That will be addressed in the spring.

Re: Time to Upgrade. Input needed
the .63 is on. I am not sure whether I want to spend the cash on a twin disc clutch or risk trying to find a cheaper clutch that will last.
I do not want the recirculated dump tube anymore. Can I convert it to atmosphere by just hacking the pipe off and welding up the hole? I really dont want to have to change the downpipe if i do not have to as its welded to the exhaust.

I cant stand the loudness of the open dumptube, i cant even hear the motor over the noise. If it was a drag car oviously i wouldn't care but for a street car i always recirculate. Some ppl love it other dont...if done properly the power loss should be really minimal. i made 411whp with it recirculated on a t3/t4oe 60 trim. .63 a/r. 480 with nos. Would i have made more open dump? Yeah probably but too me its not worth the noise. Just turn the boost up another psi and you have youre difference in power loss (if done correctly). Its all preference tho.
Re: Time to Upgrade. Input needed
That depends upon how the dump is routed. I went from open , to recirculated , back to open dump that was routed straight down instead of along the back past the transmission. Made a BIG difference in sound and noxious fumes. On a lot of the ones I've created you barely hear the difference.

this looks exactly like mine. However mine has what appears to be a catalytic converter welded to it on the end followed by a huge resonator shortly thereafter. noise does not really bother me. I dont drive the car enough to mind it when I do.
So if modifying mine can make a decent increase in power and/or just make the flow of things better I am all for it. I am emmisions exempt for diving under 2500 miles annualy so thats not an issue either.
As far as vtec and an .82 I already installed a new .63 and I do not plan to ever put a vtec head on the car. This one is staying just an LS. Now the mr2 on the other hand is a different story........b20v ftw. but thats not til I pop whats in it already.
But back to the topic of hand. Modification of the down pipe. Can it be done. SHould it and are there gains to be made?

Re: Time to Upgrade. Input needed
This is my current Setup. made 325whp/290tq. I Would really like to get it up around 450 on pump if possible and over 500 on race again if possible. What route would I have to go to get there? Car only sees 2500 miles a year.

Re: Time to Upgrade. Input needed
Would a Garrett 3071R be a better match for the .48 AR hot housing for a strong midrange in a b18b ls? Asking because I live at 5000 feet above sea level near the equator in Medellin, Colombia. Our roads are small and want to commute in a fun dd through the mountains climbing towards 8500 feet above sea level and quick spool is a concern. Think surge won't be a problem because of a ported shroud compressor housing.

Not a bad choice at all.. ;-)
