So just ordered my Stillen SC

clkio

I am currently working on it. I am really excited to see how much she will put down after meth as my engine is very low compression and my tuner doesn't think it will help alot with power. My engine spec
HBR performance built VQ37VHR Bore 3.7805 Stroke 3.460 Wiseco k643m96 dished 8.5:1 Pistons, Wiseco 9600 XS Rings, K1 Billet 4340 Steel H Beam connecting rods.

Z&I

Like that Photo gave me a few ideas.
Looks like you used to have woofers and now you have drywall... :-)

I will be installing the AquaMist water/meth injection.
I have the 9.5 CR Carillo pistons and rods - race bearings and ARP bolts.

Will be posting all of the particulars once the build is satisfactory completed.

8.5:1?! holy hell man that's low. have you tuned the kit with the new engine build yet or still in the making? are you looking to go much higher psi than just the upgraded impeller?

clkio

You see mikey, I bought a used supercharger kit from g37 forums and the kit had all the upgrades done to to it (pushing 12.5 psi) on the stock engine, car was making around 480whp and 357 torque, I went ahead and installed the meth kit but didnt tune yet. After few days of driving with the supercharger, engine blew (before I got to tune for meth) so I found a great deal on the rebuild engine I have right now. Unfortunatly, car made less power 462whp but made 380 torque but still not tuned for meth. I will be running meth around March and see how it goes. If I am not happy with the setup at the end, I will be removing the supercharger, selling it and buy a TT as the built engine i have now is better for a turbo setup.

mikey1600

fair enough, thought you would have lost a lot of power going from 11:1 to 8.5:1, turbo setup sounds good, I'm still torn about doing all the changes to mine now, probably too much $$ compared to the gains. Still waiting on pricing back from vortech supplier here in Aus to do the upgrades

Out of curiosity, how much is this going to cost you? Dont get caught up with the numbers because uou are absolutely right about the $$ going to be spent vs the gains. Extra 60hp will cost you maybe 2000? Why don't you sell your setup all together to a turbo? The reason I ask is I bought the stillen kit used of the forums for $4k with all the upgrades done as well as walbro 340 fuel pump and 1000CC injectors which was the best deal at that time. Personally, I wouldnt put the money on rebuilding the kit since I am spending thousands, you want more power, sell the kit and buy a TT because the thousands you going to spend here will yield you a lot more gains than 60hp.

mikey1600

yeah I hear what you are saying, it's going to be easily over $2k for the upgrades, no idea on HP gain really at the end of the day.

only kit I can get here in Aus is $10.5k and it's basically the exact same as the original GTM stage 1 kit, which for me is just way overpriced, none of the other US kits will fit the RHD setup. So would really have to get someone local to do a turbo setup, aka guinea pig, which I really don't want to be around here.. so unfortunately it's kind of do these upgrades or nothing really.

clkio

I am almost 100% certain your stock engine will not lost long if you upgrade that kit so here goes another 5-7k. Enjoy the car mikey, the headache and agony that I went through when my engine went and thousands spent was not worth the little extra power.
