Dave, I drafted up a lengthy PM to you yesterday regarding the FrozenBoost core you're looking at. But my daughter managed to kill my browser session, so I lost the lot...

:(

I'll get back onto it shortly, but in summary, I reckon it could be a plan. Especially considering that you can orient it in whichever way it fits best when using the OEM location. A small front-mount heat exchanger, and one of those Bosch pumps would be a great start (plus a few litres of coolant in a reservoir). Jaycar do a temperature controlled switch (with hysteresis) which could provide pump control. Too easy...

:)

Based on my 'not gonna chop the front bar' theory, it's also probably about the best that could be achieved.

And I think I might upgrade my GP99 pump to a Bosch unit in the DR too.

lol pity about the PM :) but going off the sizes Rob (KiwiRS4T) provided in the first post for the SMIC, the biggest difficulty fitting a core that I can see (purely as a "thought experiment") would be the height constraint of ~225mm (that's not a lot).

Whilst FrozenBoost don't give any idea of power figures/suitability for a given core on their website, and I haven't been able to get any out of them even when asking about a specific core, the one included in their '600hp kit' sounds like the size i'd need, bit conservative I hope. That's 12.25" long/high though, and that's too high (though it does include the end tanks and pipes which stick straight out the ends).

So I think the biggest difficulty for me would be A) getting it to fit height-wise and B) getting the pipes in the right location, because I am hoping to be able to use a short elbow and make it basically fit in the stock SMIC location.

Though my research has purely been guesswork so far. I saw these cores at first and thought "gee that one looks a lot like the SMIC"... still looking for something more exact dimensions-wise and not sure how much metalwork ( :ph34r: ) would be required to make it fit... the aim is for none, just pipework and mounts/hangers.

Gonna use the Bosch pump in the DR? Should be more than up to the task if that other little inline pump was enough. I wouldn't think a water-air system would need much in the way of a huge pressure or flow, though - just reliability.

Yeah for the front mount heat exchanger one could use just about anything surely - on the site it seems to suggest that it won't have to deal with engine cooling system pressures either.

PS if and when I do get to taking my whole front bar off to measure/fit something like this, I am probably going to want to get it resprayed 'cause the chips/cracks are getting bad and starting to work their way up the front lip so could be an expensive exercise :)

Cool... good size & shape of radiator. Looks like one of the many kit configurations available from Frozenboost:

http://www.frozenboost.com/index.php?cPath...10dfc0c1dd16dc8

OK so there are only 3 on that page... but view any of the kits and you can select various different options for pump type/radiator size/fans/reserve tank etc.

Looking thru Frozen Boost goodies. Anyone know how accurate their A/F gauge is? If it isn't what are the alternatives to get reliable real time A/F mixture readings. I have a DFA and controller but not yet wired in. Would that be a better option?

The Frozen Boost site suggests that their A/F guage can be wired to your standard O2 sensor which means that it won't be accurate enough for tuning purposes and will therefore be not worth it. Fitting the DFA is a good idea but it can only alter the AFRs and will not measure them. You will need to get it tuned with a wide band meter (time for a dyno?).

I don't know what the ARC smic is rated at. I saw some big figure somewhere but can't remember what it was. I have emailed the question to the ARC website that you linked to.

What power are you making at present? Please be sure to let me know if you are ever thinking of selling it!

Just got my car retuned (ECU reflashed). 179rwkw. That's with 3" turbo back exhaust, ARC SMIC, highflow panel, RB20 actuator and 12psi going down to 7 by redline. My Boost controller wasn't connected propperly but it is now. But I think I'm getting around 13-14psi now :) but I don't think it's going down :ermm: (turbotech controller). Got a Jaycar IEBC coming so will hopefully get the boost issue fixed although it is minimal.

Once on boost the car just gets up and goes! Very impressed in the results from the tune. :)

Great to hear Dave, sounds pretty good to me from the stock turbo :) Not sure why you changed actuator instead of the bleed? But meh great stuff. Do you have an auto? I'm making similar power (~190rwkw) with a few more mod's then that, but stock R34 sidemount, same engine & running gear (mine's auto though) and I'm wondering why I'm not getting more from my GCG hiflow.

How much boost are you running now Dave? have you installed a Nistune chip? If you are running 1 bar with a decent tune you should be making well over 200awkw poss up to 210- 220.

    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
    • I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
    • Is it alright to top up with just another green coolant?
