If I had it to do all over again this is what I would do. Perring Intercooler and Beam You can order the Perrin Front Mount without all the piping, its just the bumper beam and intercooler Then I would take it to Mainstream and let Turbo Dave make you piping. He did part of my piping and it turned out really nice. You will end up having less in it than if you bought the Perrin Kit. I also think you can make a topmount work if you are willing to remake the brackets. Matt
i really doubt i will stick with a topmount... however, i was just curious as to fitment... i figured that if a certain kit can fit with the stock TMIC, then it would also fit with an aftermarket TMIC or an aftermarket FMIC since all these intercoolers are designed to fit with a stock mount turbo u say that buying the core and having dave fabricate the piping would be cheaper? i was thinking of going with the aps dr525 since the inner ricer likes the black core and red piping
The APS Kit is really nice and it seem to fit really well on the 35R car that Scott was working on the other day. Matt
was that the UR 35r car? do u know if he needed any custom piping or did he use all the APS piping? maybe i should ask scott to respond here
UR makes/sells adaptor pipes specifically for the APS series fmic as well as the TurboXS/SSAutochrome series. No need for custom pipe bending, unless you want the magic hand of Dave on your car.
UR kits are expensive though... i know th t3/t04 kits are well priced but the UR gt30r kit retails for $3400 while the perrin kit retails for $2730 i have seen the perrin kit <2500 on nasioc... havent done much research on UR
slowwrx: im looking on the MSPT page and im not sure which intake you are talking about... is it the perring CAI? http://mspt.net/shop/index.php?cPath=25_58_85 by the way, notice that the 3 APS intakes at the top are apparently free
The UR cold-air intake also moves the filter and MAF sensor/housing into the fender well. **Guys my apologies, I'm really not trying to sound like some UR fanboi, just trying to help with all the options** They don't have it listed on their site by itself, have to look at the turbo packages to see a pic (though there's probably a pic on nabisco somewhere).
the more research i do on it, the UR kit seems more and more attractive... fitment seems flawless and it isnt plagued with the issues that the perrin kits seem to have... perrin also uses an older T31 housing with a 2.5 inch outlet instead of the GT housing (3 inch outlet) that the UR kit uses... however with the housing and downpipe design, perrin claims no loss in power or increase in back pressure, both are claims that a lot of people dont seem to believe in terms of getting cold air into the engine, the UR kit has 2 other advantages: (1) the kit comes with a CAI and moves the MAF into the fenderwell, which also helps resolve idling issues and (2) they have a nice FMIC kit that doesn't send the cold pipe over the turbo (http://www.ultimate-racing.com/Products2/STi-06/STi_FMIC-Kit.shtml) and is designed to fit with their rotated turbo kit so it seems that the UR kit is significantly better than the perrin kit... however, the improvement comes at a significant increase in cost...
Amen brotha!! Both on the +'s and -'s to the UR kit. /UR fanboi flamesuit on/ UR will be the way I go. **unless the twin-scroll kits magically appear by then**
one thing i dont like about the UR kit is that the wastegate dumps straight down... however this will make it a lot easier to install/uninstall if needed... how much trouble does it add when the wastegate gases are routed back into the downpipe? im concerned with ease of install/uninstall
I'm considering switching from the Perrin kit to the UR kit, Scott is checking on pricing for me right now.
well, im more concerned about the difficulty of installing and uninstalling the downpipe if the wastegate gases have been routed back into it... i assume when u uninstall it, you disconnect the wastegate first and the the turbo?.. are those bolts easy to get to?
found a thread on NASIOC today comparing the .63 and .82 trims on the perrin kit... supposedly the .63 makes only ~360 whp which is in the range of a 20g?!?!?!? is this legit information? didn't get to do more research on this but i'll post updates if this doesnt turbn out to be true
So many variables, intake air temps(fenderwell or enginebay) Which cover is on the compressor side of the turbo(4 inch, 4 inch anti surge, 3 inch) Whats the discharge side on the compressor (2 1\4 or 2 1\2) Intercooler piping, 2 1\2 or 2 1\4 TGV no TGV You get my point, hopefully after the wedding I will have a little more time and we can put mine on the dyno. Mines a .48 and I can assure you that we are very close to 400whp. Matt
in all my searching on the subject of .63 or .82, I've always read that the real difference is about 20-30 whp in the upper rpm range. I don't have any first hand knowledge here, but I would bet that a .63-based turbo would be great for auto-x.
2 days ago i rode in an STi with an FP red and methanol... i must say i was way more impressed than i was with the car that had the GT30R .82... the GT30R had absolutely nothing below 4200 rpm and felt like an on/off switch... the red felt more linear and threw me back in my seat right before 3700 rpm... to top that off, the red also made more power up top... so in my opinion, that particular red completely outperformed that particular gt30r... kinda goes against the theory that rotated allows quicker spool and more topend :dunno
Did the car with the 30r have Meth?? I wonder how much faster the meth was helping the Red spool. Any idea if the Red was equipped with the 8cm housing?? Now that they are building these 20g/green/red turbos with the 8cm housing, they look much more impressive
the 30r had meth as well... both had front mounts... the red was internally gated too... not sure about the housing
The car that Milo rode in is mine.:naughty: The Red that I have has the 7cm housing. The 8cm housings are very hard to come by these days. You just have to ride in my set up to believe how strong it is. Ask Milo, he'll tell you.
yup it was urs... i didn't wanna share it on here before i asked u if it was OK man i must say, it was insanely strong... even with 5 people in the car... torque hit strong by 3700 rpm completely outspooling the GT30R .82 that i rode in... after riding in this car i'm strongly considering going with the SZ65 instead of a GT30R also ur meth tank is sexy... ur engine bay is probably one of the cleanest setups i have seen another thing i like about the stock mount turbos is that the FMIC cold pipe is nowhere near as close to the turbo as the rotated setups go
I appreciate the props. Next time, get Scott to take you out just you and him. Feels even better with just two in the car. Good luck with your decision!
