33 Is Finally Going Dyno Graph Attached

[bazr33]

Howdy after 6 months of not being able to drive my car for licence issues and pulling my bits off my car, and upgrading

i am wanting peoples opinions as to what parts i should look at getting while i wait.

car as at a workshop now getting exhaust and inlet manifolds custom made, with a 45mm turbosmart ext wastegate. (GT30r Turbo)

widemouth dump pipe custom made and putting on a xf throttle body.

i currently have on the car PFC, FMIC, walbro 255 fuel pump, 555cc injectors, Z32 AFM, nismo fuel reg, AVCR. turbosmart BOV, apexi pod filter

car previously made 320rwhp on a hiflow turbo on 15psi. Wanting to see 18psi with the gt30r when i get it going.

still on internally standard engine. But currently in the middle rebuilding a rb25 engine, to swap later on down the track.

any suggestions,

the car is being used mainly hard street use.

i have been thinking of custom oil cooler, and a surge tank, but unsure whether i would need them or would help.

A surge tank wouldnt hurt and id think about an oil catch can as well.

[NYTSKY]

A decent clutch.Because at 18psi you will probably make between 280-300rwkw.

[dangerman4]

loose the walbro, and stick a 044 intank.

forget about the oil cooler and surge tank.

[bazr33]

still haven't had my car returned to me yet, but have been making progress with my engine rebuild.

thanks for your comments about parts, and have been keeping my eye out for them.

For my forged engine, i also would like some opinions on parts and what power to expect with parts being used on previous engine (PFC, custom ex and inlet manifolds, gt30r turbo, and fuel supporting mods)

I have : ACL rod and main bearing kit, ACL 20thou Forged pistons

performance valve springs

Spool rods

Retaining std cams, cam gears, valves.

engine gasket kit

head and block will be going away soon to have machined, bored, balanced etc

Hi guys

just seeing if anyone would like to make comments about the previous post about my forged engine.

Also considering i'll be making not too bad power when i get my car back, and as nytsky stated about purchasing a new clutch.

What clutch would still be suitable for the street, and occassional drags, and for a reasonable price?

[Dale FZ1]

Exedy cushioned button.

Plenty of bite, not too grabby or shuddery. Price is very reasonable too.

Re your parts: forged pistons and rods won't "make" more power. But they will make the engine more reliably able to withstand extra power/load over the long term. The extra grunt comes from mass air-flow throughput. So whatever you do with engine breathing (manifolding, porting, port matching, turbo spec and boost, inlet/exhaust, cams) and the quality of the tune that goes into your PFC will be what essentially dictates the power you'll make. Given what parts you've used, you should have the potential to hit or exceed 275rwkW. And 300 may not be that hard to hit either.

In the normal matter of interest, can you post up the ID tag number off your turbo? There are many flavours of GT30, so it'd be interesting to know exactly what spec you have, including the housing A/R.

Overall sounds like you're going to have a lot of fun.

[bazr33]

i will post later the ID of the gt30r turbo, when i get it back (as its with the car at the shop) but what i know at the present time is it has a .70 compressor housing and .82 turbine housing. rated 500hp, came from GCG/honeywell.

Exhaust manifold is going to be similar to extreme manifolds one, where the ext wastegate will be situated underneath the turbo, and plenum will be similar to the plazmaman item.

Car will be taken to godzilla motorsport for a tune, and want to see 18psi running through the turbo, for the short term. I don't want to, (if i can help it) keep the internally standard engine in, as its in top condition, and don't want to damage it. So later on down the track it will be up for sale.

Also will be looking at upgrading my exhaust system, even though its 3", i think its the standard item.

Anyway will keep yas posted.

heres a pic of my new manifold with a gt30r turbo and 45mm turbosmart wastegate

Plenum is still in the process of getting fabricated

should be finished this week

[Dale FZ1]

Looking good. What is the design of your manifold? Got any pics of it bare (as in off the engine, or without turbo bolted up to it)?

Still interested in the CHRA number off that turbo too, if you have it.

[bazr33]

Where is the location of the number on the turbo?

there is a number on the compressor housing is that is it

its 409722-26

[Dale FZ1]

It's on the centre cartridge, on a plate that is riveted to the casting.

Something in a similar manner to the picture below:

[R31Nismoid]

MAke sure you coat that strut tower with heat resistant film, that exhaust housing is extremely close to it

[bazr33]

oh ok, i will have to wait till i get the car back before i know what the number is on the plate.

so hopefully it will be this week when i get it back, and everything is done.

i havent got a pic of the manifold by itself but will have one next week.

i will be purchasing some heat wrap for my power steering hose and other hoses that are coming close to the manifold and turbo.

the heat film you are talking about, is it come in the form of some sort of spray or like a glad wrap etc?

Also be getting a heat shield if it will fit for the turbo.

[Dale FZ1]

You could get the turbine housing HPC coated. Depending on finances, look at doing the manifold and dump pipe(s) too. Not cheap but it is good stuff.

ACL do some funky looking sheeting that can be shaped into a good heat shield. Same stuff used in the Ford XR6T, and it is not terribly expensive. Done right it will look something like a factory job, though it might depend on how much bling you want from exposed bits n pieces.

i have bough the acl corrugated metal stuff, it sounds pretty kool and can withstand up to 900deg.

Also have bought 30m of red heat wrap for hoses and etc. Might of bought a little too much but i wont run out.

after buying the stuff i forgot to ask the guy thats doing my car if he had these items and he did and cheaper #$%$#!!

Plenum is still left to go with xf throttle body.

[bazr33]

I have recently received my car back finally

Now i have the fun of connecting up vacuum lines fuel lines etc.

Also can i clear up that the blowby outlet off the rocker cover, does the hose go to the intake manifold.

Gt30r id tag is - KE0106j

7001770 5014

i have to also purchase a smaller washer tank bottle because of my accelerator setup off the xf throttle body.

Thinkin of getting one of the greddy washer bottles.

[bazr33]

after a whole lot of farkin round with my car, another exhaust manifold havin to be made etc etc.

the car is finally running on 14psi for now safely and on 344hp at the treads.

pickin it up on saturday so should be fun

[NYTSKY]

I bet you are as proud as punch to be finally getting to drive the thing again.

Putting a 3037 on mine very soon.I got the surge slot cover on mine tho

Oh just looking at yours being a .7 cover as mine is a .6

[SPINR33GTS]

Very interesting wat stuff did u have to move to actually mount the gt30 power steering apears to b moved and washer bottle was that all or is aircon removed to run bottom intercooler piping aswell has to b moved?

Interested in maybe doing something similiar in the future just wondered how involved it was from say fitting a normal high flow turbo ie manifolds etc wat sorta budget did u have on this ?

thanks ROry
