Upgrading support systems

I'm gathering information for my next series of upgrades.

I have a 95 R33 GTS-t. My list of mods includes

HKS pod filter

3 inch exhaust from turbo

Power FC

AVC-R

and a FMIC. = 192rwkw.

I would like to upgrade the turbo with the aim of approx 250rwkw.

My questions are about the support systems.

How much power will the standard clutch handle?

I plan on a new pump and injectors. I was thinking bosch 044 and sard 550's

Does anyone else have any suggetions. Has anyone used these injectors?

Value for money?

Do I need to get anything else apart from the injector and collar?

I dont plan on going internal in the engine at this stage but if I do I cant see me going over 300rwkw, would these injectors be ok.

The fuel system so far is the one thing that is causing me the most confusion so any help would be good.

I have an almost exactly same setup and was looking to upgrade to 230 - 240 rwkw. I decided against it mainly for the cost, once you reach over 200rwkw parts start to get quite expensive.

What support systems you will need:

Z32 AFM

550cc high impedence side feed injectors

Min. heavy duty clutch, twin plate is better

Bosch 910, 040 fuel pump.

Comments:

. You will definately need the Z32 AFM, you will maxing out around 200-210rwkw on the standard.

. 550cc injectors is recommended, however some say using a rising rate regulator is acceptable on stock injectors up to 240rwkw. I prefer not risking it and getting the injectors done. Sard prices are good, but they do not come with the collar necessary for straint plug-in fit. I sourced HKS for 78k Yen.

. I was going to continue to use my heavy duty exedy clutch and see how it went. Without launching hard at every opportunity it should have been OK. It's more a matter of torque than anything anyway. Twin plate would give you no problems - but adds to the cost.

. I was planning on getting the 910 fuel pump because my target was 230-240rwkw, and like you don't plan on doing internals. Getting bigger pump is still OK.

Now that I have helped, can I ask what turbo you are looking to use for this?

Thanks for your help Torrens.

I havent chosen a turbo yet. I'll have to look into that later but I thought I better get the other stuff sorted first. I would prefer a turbo that would not be laggy. I am more interested in having good midrange rather than outright power at the top end. What turbo are you going to use?

as per my signature, the only upgrade to my fuel system was a bosch 910 fuel pump, stock injectors, stock fuel regulator. The injectors are at roughly 70% duty cycle. The trust td06 or a garrett gt30 is probably the go for your turbo upgrade.

Thanks rob. Are you still using your standard clutch?

No Rob's clutch isn't standard.

I also am using stock injectors and have over 300rwkw, but I use a Malpassi fuel reg.

WOW I didn't think that was possible. I have been told by my workshop that I'll need new injectors if I want to go over 220rwkw. If i can get away without getting new ones that would be good. Does anyone have any opinions good or bad on their aftermarket clutches?

      Oof, I will forevermore have those shredded gears in mind whenever someone talks about showing mechanical sympathy towards their car. Thanks for the photos, fascinating stuff!

      The holdups last year were drivetrain related. I had the car out right after getting the bearing issue resolved. Third launch and the car didn't move after releasing the clutch. It had sheared all the engagement teeth off the 1st gear.    Thankfully no other damage was done. I set an aftermarket gear beside an OEM gear and found that the engagement teeth on the OEM gear were much larger and better supported. Looking through my bin of spare transmission gears I found that there are two types of tooth on the OEM first gears - the larger tooth and the smaller tooth. It looks like most aftermarket gearset manufacturers base their design on the smaller tooth. OEM large tooth left - Speedtek, OS Giken, etc or OEM small tooth right Decided to give that larger engagement tooth a try. Pressed the ring off an OEM gear and sent it to a transmission manufacturer here in the States. They did their "faceplating" operation with my synchro ring on the Speedtek gear.   I reassembled it, took it back to the track and promptly destroyed the gear itself.  I'll rebuild this and use it as a spare - thankfully just first gear and the countershaft are damaged beyond repair. Definitely disheartening but my welded on engagement tooth ring held up!  Moved to Speedtek's dog engagement design as the gears appear to be much stronger. So far they have taken much more abuse at the track. Also scored a Stillway lockout from the Netherands for super cheap. It's for some other RB transmission so it took a bit of fabrication to fit but honestly a very easy job. I also had to heavily modify the gates as they were very different.   Then for some reason at the last test and tune a silicon coupler below the throttle blew off and took out the radiator and fan. Thankfully it was in the burnout box and not down track. This car is really beating me up - I still haven't made a pass in it. Ran it through the gears many times on the street but it keeps biting me at the track.  Currently in the process of replacing the radiator and remaking the throttle pipe to remove the coupler and use a cast 90 and a vband. I WILL get this thing down the track...

      Covers most of the above points really. There's a few exceptions but most just see driving as an irritating but necessary task they must complete if they want to get anywhere on time. Also see it as a good time to show their awesome multi-tasking abilities on their mobile and/or doing their makeup.

      I don't believe I posted pictures of the second oil pump pickup I added so here they are. Data shows it gets oil pressure up to the relief pressure much earlier in the RPM. Is that important? Not likely... This was just another attempt to fix the bearing issues.   I also heavily opened up the inlet to the pump since it now had to flow oil from two pickups. I believe the diameter increased about 1/8".
