Question regarding turbo accordian hose and N/A AFM

^Just an exploding engine, haha ::w00t::

I lol'd


keep an eye on AFRs fa sho.

yes the GTE electronics are better, but it can be done reliably as he is doing it as long as the tuning is spot on.

Oil cooler is a good thing, but dont was your time with the stock toyota setup, it is usuless by design. The stock cooler is to small to be an inline unit and by-passing a small amount really does no a thing for cooling and yes I have checked this myself using digital temp monitoring equipment (fluke meter with a special K-type thermalcouple) the best that we saw with the stock type cooling was only about 5* F not worth the hasle. If you want an oil cooler, use an actual inline unit. The best ones that I have ever used on any car and especially for the price that you can pic them up for is the stock units on the 86-92 Mazda RX-7's. They are very effiecent (and have to be do to the fact that 1/3 of a rotary cooling is done by oil where as on a normal piston engine, that number is about 1/6 or so) and another nice thing that is built in is a thermostat.

Thanks for the info. If I can't find any RX-7 coolers, are there any aftermarket ones that are up to par for a good price? Also, I noticed you went NA-T before, what is/was your setup?

550 Injectors, Lexus AFM, IC and piping, SAFC, Turbo ECU (88 turbo ecu I picked up recently), turbo, turbo manifold, turbo elbow, downpipe, bov, I have a fel-pro gasket installed, boost gage, and turbo fpr

hows that little list sound.. can I swap out my ecu with the turbo one I have and still use my stock wiring harness?

Seeing as how you have a Lexus AFM and a Turbo ECU I'm guessing you're going full NA-T?? In which case you will need to use the turbo wiring harness...and your parts list will need to grow quite a bit :naughty:

no prob....

yeah, I was NA/T for a while, setup was a stock GE motor with a Titan Motorsports MLS HG and all stock turbo and IC, but I built my own 3" DP and 2.5" IC hardpips. I was running a full stand alone though. (only because I had it sitting there from a past RX-7 that got totaled). now that the turbo went south, I am in the process of doing what my sig says. (1UZ V8 swap)

Also about the oil coolers, pretty much most any aftermarket one is better then none or the stock type setup. As for pricing, not really sure as I have not really priced them in some time cause I dont have much problem finding RZ-7 units. Just make sure if you do pick up an aftermarket unit that you for one do not get anything that says that it is a auto trans oil cooler and the you get a by-pass type thermostat. The thermostat can be bought for summit racing for pretty cheap and probably just about any decent speed shop in your area.

Also, if you cant find an RX-7 unit, let me know. I could probably get you one for pretty good price and sent it to you

what more will I need? (I'll do a full 3" exhaust from dp back)...

 

[SupraDerk]

Turbo, Turbo manifold, turbo elbow, downpipe, intercooler, intercooler piping, BOV, turbo ecu, turbo engine harness, turbo o2 sensor, turbo injectors, turbo fpr, CPS, coilpacs, coil wires, turbo ignitor, a second knock sensor, turbo AFM, turbo oil pan (unless you get a bung welded onto the NA one), boost gauge, cometic or metal or stock turbo headgasket, oil cooler

There are some odds and ends stuff, brackets for intercooler and oil cooler and afm and all that and the lines for the turbo and some other stuff.

That's pretty much it, if I left something off someone feel free to add it.


Oh, some say that the turbo power steering reservoir and lines are needed, but I've seen "custom" setups that keep the NA's right where it is. They pieced intercooler piping together using civic intakes and such


Edit: If you can, find the turbo fan, fan clutch (I'm not sure if the NA fan clutch would work, but most times the fan and fan clutch are sold together) and fan shroud

hmm, it would probably be cheaper to go with a jdm turbo motor eh? That way I can rebuild the turbo motor and keep my car na untill the turbo motor is finished.. then swap.

 

[SupraDerk]

Depends on you really. I've got most of the stuff and so far it's cost me about $500. My NA motor is solid and I know the maintenance history of it and the condition that it's in, so it makes for a good base. JDM engine is roughly about $700-900 for just the engine and you don't know anything about it. Could be good, could be horrible, it's really a gamble. And then you still risk the chance of having to replace parts on the engine and find the rest of the missing pieces, racking up the bill.


The NA motor won't be as fast as the GTE on the top end, but low to middle range it'll hold it's own. So again, it's up to you and your goals. :bigthumb:
