Small update.

Not sure what the issue is, combination of cam timing too far and something else we are yet to find.

Lots of torque, great to drive, but clearly falling over very quickly.

Easy fix- all in the cam timing

Now running 20psi, plenty left in it. This is beautiful to drive on the street. this with a 200cell cat in place too!

[Simon-S14]

results are in.

Blue us RB30 orange is rb25. full comparison and nothing else has changed except the bottom end.

turbo is 3076 56t with 0.63 rear... falls over pretty hard and adding more boost doesnt increase it.. so rear is a restriction thats for sure. Need a .82 rear for it.

Made 400rwhp (298rwkw) at 19 psi and 415rwhp (309rwkw) at 22 psi. Made 400rwhp by 4800rpm. Didn't bother turning it up more due to the stock head internals and restrictive air filter and exhaust. Full boost at about 3500rpm.

The air filter was almost sucking itself inside out. The cat and catback are probably a restriction too but in saying that the car is very quiet.

It is what it is. I'm not happy yet so better results yet to come

stock (machined) exhaust manifolds

1st round, about 1.2 bar, R34 elbows, greddy downpipe, R34 stock catalic converter, 3" Fujitsubo catback (60mm backbox inner diameter):

2nd run, about 1.3bar boost, exhaust changed to a 3.5" one that came off an MK4, but still with some 3" restrictions, downpipe modded to fit a 100cpi catalic converter (boost reading on printout is wrong, measured at wastegates):

3rd run, still on HKS GT2530´s, but now with about 1.35 bar boost and fully custom 3" elbows + downpipe:

Now with different custom intake piping and GTX2860R´s on about 1.7-1.8 bar boost (and obviously a bit less ignition and not yet optimised A/F ratios) - we usually ran the car at 1.5 bar, just tried it once on the dyno with more boost (and were disappointed by all the results that day):

[AndyStuttgart]

So, car finally got mapped but it looks like stock fuel lines give too much backpressure - so 1.7 bar was the save limit before mixture leaned out, which disappointed me a bit.

We still could get much more power out of the car, by adding about 10 degree of ignition timing - no wonder we made such poor results the last time ;-)

Stock RB30 block apart from new rings, bearings, big end bolts, Tomei sump baffle kit and N1 oil pump. Stock R33 head cleaned up, VCT connected, Tomei head gasket and adjustable ex cam gear. Sinco Customs exhaust manifold, GT3540R turbo with .63 ex, Synapse 50mm W/G, Venom 5in 100 cell cat, 3in exhaust with straight through resonator and cannon. Hybrid FMIC, Greddy copy FFP, HKS Sequential BOV, Deatschwerks 550 injectors, stock throttle body, fpr and rail. Walbro in tank fuel pump and Bosch 044 from surge tank. Link G4 ecu. 98 Pump gas.

Plan to install some better plugs, fine tune W/G and retune for a few more KW but will probably leave it at that as I don't want to push too hard on a stock unbalanced bottom end.
