I'm very close to purchasing an S15 after having just sold my R33 gtst. What sort of 1/4 mile times are people with S15's pulling with what mods?

My girlfiriends parents have one which has some annoying rattles in the dash with only 11,000kms on the clock which is a little worrying in regard to the build quality but never mind.

Anyone else out there who has gone from an R33 GTST to an S15? Any regrets?

Any feedback is appreciated.

Bryce.

I have a few friends with S15's, one has exhaust, front mount, 14psi boost, pod filter and has done a 13.47 quarter mile (on lowered King springs).

Another friend has done a 13.49 with 14psi boost, exhaust, pod (no intercooler) with tein type flex coilovers.

Theyre damn quick cars, and there seems to be quite alot gained with them from suspension upgrade as well as normal engine upgrades. I doubt the friend without the intercooler wouldve run such a quick time without the coilovers.

As for build quality, they are a bit rough around the edges, as are most "cheap" mass manufactured sports car (the cars arnt cheap, but compared to a ferrari etc, you cant expect perfect build quality). A friend has had his since 10,000km's and its now just done 35,000km's, and there are a few rattles coming from the plastics around the dash, but nothing to be too alaramed about (other friend has a 1999 model and done 90,000km's, it rattles but hasnt fallen apart yet).

Theyre very nice cars and I was looking for one but ended up going with the skyline, as for me nothing compares to the sound an inline 6 makes :rofl: But they are sweet cars, and im sure you'll be extremely impressed.

Hope this helps out a bit.

as a smaller displacement engine they will feel slightly more sluggish than a skyline off boost. But give them a good prod in the backside and they pretty much go as fast as a skyline with similar modifications. less weight compensates for less power/torque.

Do note that its slightly more difficult to live with an s15 on a daily basis compared to the skyline to due the noticable lack of cabin room. If you are a big dude u will find it harder to get out of an s15 than a skyline.

I had an S15 before I got the skyline. They are very nice cars, ull be pretty impressed, as ppl have already told you, you can get alot of power from very simple mods and they will give the skylines a good run. At round the 15000kms my horn cover on the steering wheel started rattling and a couple other minor rattles but nothing major. Overall a great car.

    • They care about emissions, and cost the most. Save weight where possible, and make manufacturing easier. Less material also let's the engine transfer heat to water quicker, and bring the engine up to temp quicker, better for emissions and getting them past their warranty period.
    • I was under the impression the reason why OEMs are going with solutions like relatively thin "right-sized" cylinder walls with technologies like PTWA and open deck is because they care a lot about whatever marginal knock margin benefits they get from that vs the structural rigidity benefits of a closed deck block and thicker cylinder walls. I also see some weird stuff like plastic inserts in the water jacket around the cylinders to try and equalize cylinder wall temperatures. re: the PRP blocks and heads at the end of the day it's hard to know what is and isn't going to work there, just have to see what the initial buyers say about it.
    • Which is why I didn't mention that hardness testing, and specifically mentioned the bore and deck thickness testing. Yeah, not really. The bore temperature will be a lot more even around the top half inch or so, where the material distribution is dominated by the deck, and which is the only place where the bore surface temperature heating any gas in the cylinder is likely to have any effect on detonation. Think about it. Another inch or so down the bore, you might have a hotter spot. The gas there might get a bit hotter, then the piston rises squeezes that gas away from there at high speed and mixes it with other gas from nearby. Instant dilution of the problem. I'd be surprised if it was an issue at any time other than in racing engines or OEM dev engines being run at the ragged edge of tuning. Say what now?
    • https://dsportmag.com/the-tech/education/engine-tech-material-hardness-testing/ The PRP testing on block hardness I'm not sure how much it actually can be trusted. The thinner cylinder walls on RBs is a bit of a problem vs 2JZ but it really depends on the design goal. Siamesed cylinder bores like a 2JZ cause uneven cylinder wall temps too, which means a bit of distortion induced by that + the hotspot can affect knock margin. Something that actually gives me a bit of pause with the PRP block, whether super thick cylinder walls are going to keep it from being drop-in compatible on an otherwise OEM rebuild. 
    • Yeah very valid point. I am waiting for one of the other tuners to come back from vacation so he can help me a bit when the cat is installed again. In the meantime I am going to finish up my polishing and ceramic coating that I have started myself.    N45 Dr Beasley product is highly recommended for a paint primer / polisher. Using this EXO Gtechniq also for the ceramic but next time might use the light serum before hand also. Looks great.
