I've just recently bought an r33 gtst series 2 (1996). It currently has 360rwkw on eflex.

Current setup...

Greddy plenum

740cc side feed injectors

Blitz front mount

6boost manifold

Gt3582r

Walbro intank

Surge tank

Aeromotive A1000 fuel pump

And other bits and peices...

So I want to make about 450-500rwkw.

Im going to get an eflex sensor to be able to run up to 85% ethenol and 98 in emergancies.

This is what I want to do...

Head

Supertech 1mm over sized valves(purchased)

Supertech Valve springs (purchased)

Supertech titanium retainers(purchased)

Tomei valve guides

Tomei 270 8.8mm lift cams(purchased)

Tomei 1.5mm metal head gasket(purchased)

ARP 2000 head studs(purchased)

Tomei inlet and exhaust cam gears(purchased)

Bottom end

Spool rebuild kit with CP pistons

Has acl race series bearings and spool conrods etc.

Spool high volume sump

Can someone recommend an oil pump?

New water pump N1?

ARP 2000 main studs

Fuel

Bosch 2200cc injectors (purchased)

Billet fuel rail(purchased)

Walbro 460lph e85 friendly pump

Also will be going larger precision turbo but thats another story.

This list is not exhaustive and any input and opinions would be appreciated.

Are my power figures acheivable and relatively reliable?

Please let me know if I'm on the right track.

I know what your saying, I was thinking of doing a 30 bottom end but I just love a highly strung rb25.

what's wrong with a highly strung RB30? lol

it will make more power under the curve and bring any turbo on earlier than a Rb25

Aaagh. Now you have me thinking again! Lol.

Well the head is pretty much sorted I'll look into the 30 bottom end. What do you recken of the spool rb30 bottom end package??

It looks reasonable...

Would I have clearence issues between my 6boost manifold and the block??

Sorry mate, I just took it for granted that any reasonable person would have all machine work (porting and so on) done when their doing a build like this.

Thats why I didn't mention it.

Can't assume people are reasonable on here!

And I wouldn't group porting with machine work, but whatever.

I would suggest going some more modern injectors. Go top Feed ID's or something. My tuner hates that I have Nismo's, to me the car runs perfect but he reakons he could get it a whole lot sweeter with some ID's etc in there

Bosch injectors no good? I thought they were the same as ID's, they are also top feed. No?

Yes they are the same thing - 89CAL was looking at your current list and missed your shopping list.

    • So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch
    • It is the stock air box with the panel filter. Everything else is stock except the exhaust at this point, as I also went back to the cleaned 270cc injectors. I will check the RPM when the IACV is unplugged and report back.
    • As MBS suggested if this is happening when the engine is cold you're going to want to remove the intake air regulator and verify resistance + that the shutter is physically opening and closing. At -20C should be fully open, 20C half open, over 60C fully closed. At 20C should be 70-80 ohms. For AAC valve testing using a Consult cable see if you can raise and lower the idle by commanding more or less AAC duty cycle. Hopefully it's pretty linear as well, shouldn't be like 30% AAC valve is barely idling and 40% is 1500 rpm.
    • Bloody apprentices! 🙄
    • Not sure yet.  Was considering speedtek because it was rated to 800hp, but when I did some research about him I don't think I will go for that🤣 So maybe giken gear set, but I'm afraid it won't be strong enough🙄
