Great job.

 

Thanks! Was a ton of fun to do...

 

And rewarding too..

 

And my wallet loves it.. Shops can get charging a pretty penny for all the hours I put in doing the mods. If you have the confidence to mess with the delicate stuff (Especially the ECU harness) it pays off.

 

you're gifted man i wished i have your ability and time to wrench, your car is cool and fast good luck with the build

 

Lookin' good!!

Have you thought about an LSD yet? After doing a guards rebuilt unit (not particularly hardcore) I found the GT2 to handle my meager 475rwhp muuuch more predictably.

 

Thanks! Appreciate it.

I've thought about it.. I have to get some DE's under my belt first. I haven't even attempted a powerslide on a closed course before. The one track day I have done in this car, had good results. I didn't find the oversteer to be too bad, except for on gas. If I gave it boost around a corner It started to come around.

Once I do some DE's where I can slide around, then maybe I'll look into it.

 

I tooked a look at your build... you seem to have k16s on the car... with gt28 cartridge and compressor... if thats the case then your 550 plus whp car is on the money.... IM guessing your on 91 oct with 100 % meth...
your out of turbo.... those will never make 630 whp... unless you have k24 housings then thats a possibility..

Its the same turbo that EVOMS used to use for their gt700 kit. I'm pretty sure its the gt2871r... I could be wrong though. I'm not an expert on the turbo. Sam would know more. These were on his car before he sold the car to my buddy, who I got these from.

However, my turbo inlets are stock, and my exhaust still has cats.. There has to be potential for 30-50 more hp with some more supporting mods...

 

Great thread, subscribed

 

Can't wait till you dump the cats M. I thought you got the inlet pipes in? That is a big one. Likely why LQQK and I got more.

 

i'd say power is on the low side for pump and meth at 1.4 bar

 

So technically you can drop a ball bearing GT2871r CHRA straight into the K24 body or this will require some additional machining to make it happen??

 

This is at 1.3 bar for now.. I havent made 1.4 yet, even though the ecu is requesting 1.5 at WOT... I'm thinking some sort of restriction is holding her back. Thats why I'm going to toss the cats.

I'm not sure, but I think if any side is k16, its the hotside. The k24 hotside on my old turbos were much bigger. Bigger to the point where it actually made my exhaust significantly quieter when I put these turbos on.


Craig says he'll sell me his inlet piping once he figures out how to do filters from the turbos... Its confusing in a wet climate. Since these are our daily drivers we can't just throw a filter on there.

My inlet piping is stock- could it be choking it that much? The turbo inlet/outlet is quite small.

 

I would say from experience that it's a combination of the cats and inlets. I predict 20-30+ more wheel after that and that will put you where you want to be especially because we tuned on the conservative side...Not depending on meth. the car will feel much better too!
