Default kingpin vs godsped gt35r. Please no flames!!

Dan helped me out when i first got my sti going and now for sure im gettin the forged pistons and block from him but im looking at the gt35r set up.

Both godspeeds and kingpin looks great but whats teh difference. I have a gt spec header i want to keep and ill be going with the hydra and pe 850s.

I just want to be informed on both good and bad on both kits. Im looking to get 400 whp on icky 91 pump gas and 500 on race gas ( i dont drive the car everyday just prob 2-4 times a month to good street races)

The godspeed has a probably a better housing for the turbo as they use the fp3052 an fp3065 with the cast stainless steel housing. But you are paying for this.

Certainly no expert but seeing the Kingpin kit in person numerous times still gives me wood everytime. It's very well thought out and put together. Never seen the godspeed one before.

I am currently running the GodSpeed Spec 520R (FP3052R, GT30R) kit on my car and it has been great so far. I have a FP3065R (GT35R) sitting here waiting to go in when I free up some time at the shop. The one thing I feel this kit has over others is the fact that you will get quicker spool up due to the custom exhaust housing.

All in all you cant go wrong with either kit as they are both very well designed.

I have been running the Kingpin GT35R setup for 3000 miles and can honestly say that it is a nice setup. The people at Kingpin have always been extremely friendly and helpful. Also another thing to look at is what kit has been proven to make more power. I will let your search tell you that.

Who is going to tune your Hydra?

are you still running your original setup w/ a tmic? and if so how is the heat soak effecting the performance?

I am just wondering how anyone can call an FP hybrid a 35r? Also wondering what proof their is that a FP cast hosing is going to be better then the one that garrett uses.. I just think garrett knows a thing or two about what materials to use. From looking at 3065 it would make me think it is a gt30 with 65lbwheel, but i do not know all that much about those FP units.

The kingpin kit uses a bigger uppipe which really opens the car up.

Matt when did you see full boost on the 3052?

Good luck with whatever you choose..

God speeds kit is the same thing for all 3 with different turbos. They use their own housing so it is not interchagable with different turbos like the kit that uses garrett turbos. The god speed kit basicaly uses a GT30R with their housing for the small kit and a GT35R for the large kit and a GT30R hot side with a front side of a GT35R.

If you have a gt spec header, maybe you should contact Ultimate Racing. they have a gt35r up-pipe that works with the gt spec header.

My take... BTW.. I've owned the kingpin and Ultimate racing gt35r kits.

Attriubutes of each:

Kingpin

- uses standard GT housings - proven performance and provides the ability to swap on the fly
- tig welded, very nice welds, nice quality
- external dump wastegate, which may produce more power, but is louder than plumbed back
- will work with most aftermarket catbacks
- uses Tial 44mm gate
- aluminum upper intercooler piping included (doesn't look as nice as stainless but has some perfornace benefits..less mass and therefore less heat transfer)
- intercooler pipe path is optimized for cooler airflow (does not run over top of the turbo)
- will not work out of the box with the stock TMIC
- will work with most FMIC
- fitment a bit tight on the downpipe to firewall clearance, but on the upside, the downpipe has a very smooth transitions..more so than the others
- 2 or 3 bolt upipie
- 3800.00 retail

Godspeed

- uses custom turbine housings - may have advantages over standard housings in spool, but reduces flexibility with turbo choices-
- tig welded, very nice welds, nice quality
- internally dumped wastegate, quiter than external dump, and potentially reduces flow (perhaps >600 hp)
- will work with TMIC's
- will work with most FMIC..e-uses existing FMIC piping, but routing is not potimized due to routing over hot turbo parts
- will work with most aftermarket catbacks
- uses Tial 44mm gate
- includes intake which can re-use MAF
- 2 bolt uppipe
- 3800.00 retail

Ultimate Racing

- uses standards Gt housings ... proven performance and provides the ability to swap on the fly
- tig welded, very nice welds, nice quality
- external dump wastegate, which may produce more power, but is louder than plumbed back
- will work with most aftermarket catbacks
- uses Tial 44mm gate
- intercooler pipe path is optimized for cooler airflow (does not run over top of the turbo)
- will work out of the box with the stock TMIC
- will work with most FMIC if ultimate racing upper intercooler pipe kit is purchased
- includes cold air intake which can reuse the stock MAF or removal of MAF if necessary
- upper intercooler piping for front mount costs extra - approx 500.00
- uppipe has support reinforcement for longevity, as does the downpipe to the transmission hoising..very well thought out
- great fitment -- but compressor housing on the GT35 kit is alittle tight with the brake lines on the 05 STI
- 2 or 3 bolt uppipe
- 3700.00 retail + upper intercooler piping if needed.. (will work with perrin, APS FMIC's)


BTW...I currently own the Ultimate Racing Kit.

I don't beleive you can go wrong with any of them, but they definately all have their advantages and disadvantages as well as various nuances.

BTW.. also have a look at the Element Tuning and Perrin kits

send me a pm if you want more details.


Cheers,

Syoung298

I'm sure you won't have a hard time having one of the 35R vendors make you a gt spec/3 bolt uppipe.

Forgot to add:

all use a stock size transition from the header to the uppipe with the exception of the kingpin... approx 50mm to the 60mm kingpin kit.. not sure whether this makes much of a difference as most if not all headers are approx 50mm..

Cheers,

probably not. but it's not as easy as just using a different flange.

I saw FULL boost on the 3052R at around 3600rpms. I will know soon enough how the spool is on the 3065R, but I am guessing FULL boost at the same RPM or 4000rpms at the most.

Yes, the 3065 is a GT35R compressor housing and a GT30R turbine housing. The housing is better because of the material it is made out of allowing the housing to be thiner, where it looks small but it actually flows as much as a .82A/R housing from Garrett. Sure Garrett knows how to make turbos, but that doesnt mean they built them for the best possible performance. FP's idea for the housing was more geared toward fitment for a DSM and having the wastegate mounted to the turbo itself.

I will get pictures of the GT3065R up tonite and some comparison shots with the FP18G w/ 8cm^2 exhaust housing that I have sitting here.

I think garrett has a wee bit more R+D budget then Fp.. I think you hit it on the head, SS is used for fitment issues, and they try and play off the performance aspect..

Take some pics..

Pics will be posted once I get my camera issues sorted out. Either way, the kit from GodSpeed with the 3065R has made as much power as the kit Kingpin offers at the same boost levels, so I would have to say the performance of the turbos are atleast equal.

As I already said, one cant go wrong with either kit as they are both well built.

I had Godspeeds gt35r on my sti with stock block and Dan got me 500awhp and 500awtq with 104 unleaded race gas. So I know his kit makes power. I would say check with the shop your goning to have install and tune the car.

Do you have a dyno sheet? That is some awesome torque.

I thought you were running a built motor? Also did you ever run your 10 sec pass? I remember you were breaking the motor in and told me and a few of my friends that the thing has over 600 whp with the alky injection.

The FP housing is a .7 AR housing from what I have read. This will bring boost on fast but it will limit you on top end power. The EJ motor likes a big free flowing turbine. I am not knocking Dans kit. I know Dan and I tune his kits from time to time. But after seeing and looking at both kits I find that I would personaly want a larger AR turbine housing. The quality and finish of the FP turbo is great.

Our upipe is one of the reasons the KP kit makes the power it does. After I found this out and posted it as free info several of the other kits jumped in size. Yes our DP is tight but it has to be to flow smoothly. The KP kit is now Blow through MAF and includes the MAF mount on the charge pipe. A 4 inch coupler, intake pipe with breather fitting and 4 inch filter are included in the kit. Once this kit is instock and shipping the pricing will change slightly. But you will have a true 4 inch intake which helps in all areas of the power band.

is there anyway i can make my gt spec header and upipe work with the godspeed kit or kingpin kit. I really liked the increase in power the header gave me and id like to transfer that power to a gt35r set up

The GodSpeed kit is based on the GTSpec header. That will save you some money towards his kit as well. I am guessing yours is the 3 bolt flange?

Clark: Good Info. I wish there was a way for me to actually measure the A/R of the exhaust housing as FP is VERY vague about its size.

Here is a quote from Forced Performance's Website:

Quote:
Having a modern cartridge with ball bearings and super efficient blades isn't going to do anyone any good if it doesn't bolt up. The existing 7cm^2 and 8cm^2 Mitsubishi turbine housings were not only too small for the GT30 turbine wheel, but mass production design compromises such as an offset non-symetric volute and poor material made them very undesirable. It was decided to abandon attempts to force them to work. Design work started on a totally new turbine housing. A truly perfect turbine housing worthy of the GT30 CHRA.

The result of the research is our race inspired totally symmetric volute scaled to perfectly match the dimensions of the GT30 turbine wheel. This larger housing incorporates a built in wastegate mount which offers simplified installation without compromising boost control like inferior internal wastegates. Boost pressure can be set as low as 14psi without ANY boost creeping at higher RPM.

Another feature of the housing is the turbine inlet. 60mm diameter and as smooth as an extrude honed housing throughout the entire volute, the FP30 housing does not require a $95 port job in order for it to perform properly! There has never been a housing like this available to the public.

To avoid a common problem with turbocharger exhaust housings, cracking, the FP30 turbine housing is investment cast in 310 stainless steel for high temperature strength and corrosion resistance. Test units in the field for almost two years showed no cracking or erosion. The FP30 turbine housing casting also offers a weight savings of almost 5 pounds over the OEM Mitsubishi 7cm^2 and 8cm^2 housings.

To further simplify and reduce weight an F1 style low profile V-band clamp is used for main turbine discharge. V-band clamps are much lighter and quicker to connect than typical 4 and 5 bolt flanges. Kiss that crow foot 14mm wrench goodbye. A single 7/16 nut is all that stands between you and DP removal.

Least we forget that I do have a bigger Spec R 750 kit with larger turbo sizing than the Spec R 650 kit. It uses a 75 lb compressor wheel which is bigger than any of the GT35R compressor wheels available. Also just to point out that my kit uses all v band clamps.
