I had a few questions concerning the Greddy V-spl intercooler kit that I bought online a few months ago...this is the S14 kit , I have chosen to install the S13 instead..does greddy sell just the pipe kits for their intercoolers? ... and I know the R-spl is preferred in "high horsepower and boost" applications, but was wondering if it would handle 375-400 at the wheels and 1 bar at least... I really dont want to go through the hassle of getting rid of this kit. any help here would be great!!!!

FWIK, Greddy will sell the pipes separately but they are EXPENSIVE. Something like $150 a pipe. I think you would be better off selling the kit and getting the R-SPL kit. Or you could go to a muffler shop and have them make you some pipes.

what kind of turbo are you running to where you will get 400WHP at 1 bar?

Thanks Lucky I was afraid of that. I H8 I don't know which turbo would create 375-400 at the wheels at 14 psi ... I was wanting to know if the intercooler would handle at least 14 psi. what do you think of CTC motorsports turbo kit ? all for 3200 dollars! one thing I have never read about was whether the top mount set up created too much heat for the master cylinder!!!!! whats up with that? all these kits seem so close... and what do you guys think of the Tomei Arms B8446 kit ? Jspec says its bolt on and will clear LHD vehicles despite being a JDM kit:)

yea, they have internal wastegates, so they will fit the lhd cars...

ctc motorsports kit is way overpriced...

a lot of them do produce a lot of heat, just make and use a good heat shield and you should be ok...

I H8 UR DSM , obviously I haven't tried but, can I piece together a similar kit for less? ... this CTC kit was my newest option, as I had been looking at the Tomei kit for quite sometime...I had phase2 send me the specs and found that they were really close to the GT2835R (.86) , the main difference being inlet housing dia (GT 100) (Tomei 60) , correct me if I am wrong but doesn't 420ps equate to 414hp SAE? I am afraid to ask at what psi this Tomei turbo can support this figure...what do you think? for 2200 for a ball bearning upgrade that will mount in the stock location with 400 hp claimed potential ... good deal?

you can piece together a t3/t4 kit cheaper...either through enjuku, or going yourself to like cheapturbos.com and getting a t3/t4 for like under $600, use a inexpensive jgs manifold, or the new hotshot mani, tial wastegate, and accesorries.....kits are nice cause they come with everything, but are usually overpriced

I H8 , yeah youre right and thanks for the website , I haven't come across this site yet!!! yeah kits are cool but you pay for the convienience...like buying milk at the gas station, I will check em out , I know I dont NEED a ball bearing turbo ...at least I keep telling myself that. However, back to my first question...can the V-spl handle at least 14 psi and 375-400 hp? I mean come on... is the efficiency of the R and V cores seriously drastic enough to warrant selling this kit and getting the R core? ... by the way my V is already on Ebay so ... if you know anyone:)

i'd be weary of the vspl with 400 hp...i think it will most likely be inefficient at that level......i'd say the rspl is going to be good to that level and slightly higher...

****!!!! well im selling the thing for 735 shipped so... anyway I looked on Cheapturbos.com and noticed it was a mopar posting site for the moparheads , do I look in parts for sale or ? checked turbonetics site, they have the hybrid for much less than any ball bearing turbo...but , they do have it with the ball bearing center as well ..for like 1100 dollars!!! thats an awesome price compared to the JDM offerings. I H8 , I assume you know a great deal about the SR20DET , I have read some of your posts in the past. Are you familiar with the head designs on the S13 and S14 engines? as you know one is high and the other low port .. is the power potential drastically different ? even with aftermarket turbos? ... also I have read people bash the variable timing on the S14 and 15 engines... why is stable timing at high rpm a bad thing? (full of questions here) that brings me to cams.. are the cams different on an S14 ? or is the variable timing mechanism only in the cam sprocket? sorry for all the newb questions, well no im not sorry nevermind, but I was hoping that you could help me out with a few of them.

Yeah doc , I H8 corrected it for me ... I too was looking at the ball bearing hybrid , I dont know if I need the ball bearing stuff though. that site is great on prices, but I do not know of anyone buying from them...so far they have replied to my emails really quick, if that means anything.

yea, you can get over 400whp outta the t3/t4....

people do buy from them, although i cant say personally i have delt with them yet...

http://www.honda-tech.com/zerothread?id=237399

the honda boards do a lot of group buys with them, ask them, or jump in on a group buy for even more savings : )

i can get you turbonetics turbo's.

I H8 , I might take you up on the turbonetics offer I have decided on the ball bearing hybrid ...see what you can do!!! I was worried about whether to watercool or not. I wrote to cheapturbo , the guy says that on my setup I could run the regular braided line setup for the water ... he gets the watercooled centers for another 80 bucks though. he also says that watercooling is only necessary for the GT series turbos because they are full ball bearing. the ball bearing T3/4 turbos only have a ball bearing thrust area. they still spool quicker than sleeve bearing at any rate however.

there are two options as far as the T3/4 turbos go one is the 60 trim .63 turbo for 1.7 to 1.9 liters (ctc's turbo) ...and the other is the 60 with the .82 for 1.9 to 2.5 liters. ...now CTC's kit has a sleeve bearing turbo , I talked to chris at entuning and he says his install gets boost by 38 to 4 grand ...I want a ball bearing turbo so theoretically could I use the .82 turbo for even more top end and roughly the same spool up time as a sleeve bearing .63?

i'd say the bb will spool about 500-900rpm sooner....

my turbonetics price sheet is a fax, and came over mad fuzzy, lol, so i cant really read the prices, i dont want to give you the wrong price...it looks like it says 1680msrp, for the t3/t4 ball bearing turbo, but like i said, i cant really read it, ill ask Eloy later or something...i think turbonetics makes like 5 different turbines though for the t3/t4, i'd have to check...feel free to check their site.... http://www.turboneticsinc.com

The Greddy V-spl is holding up great at 400hp. We are running our new turbo kit, with the stainless steel top mount manifold and T3/T04E 50tirm, on my car and I have the V-spl on it. We are making 393hp to the wheels at 21psi.

Our best ET so far is [email protected].

That is with some very bad traction problems. With some real tires on it, the car is capable of low 11's. Looking at the MPH the car and intercooler seem to be performing awesome. We plan on putting a few more things on the motor and making ~425-450 to the wheels and staying with the V-spl. Greddy lists the V-spl with their T67 kit which is supposed to make ~400hp. My guess is the effiency of the core will start going down at about +450hp.

Thanks for the info on the V-spl , I just sold mine today!!!! im pretty happy about that... and instead of the t3/4 turbos I am researching the GT30 turbos right now for the SR20DET .... have you any experience with this turbo? one important question... is it common to watercool top mount turbo setups? what problems might I face..as I intend to get a full ball bearing GT30. Thanks!!
