't28' can b many things, the potatoe is just one flavour. Most T25 > T28 upgrades use the T3 super 60 compressor wheel mated to an upgraded turbine. T04b cover n wheel on a handful too Some turbo shops just supply a t28 chra and machine your T25 housings to suit, ~$500. Shop around, ask em about ur ...

T25 is a great low 200s match if u want quicker spool up/earlier torque onset and u r sure you'd stay under 300hp :lol: jdm ca18 turbine hsg is 0.48. sr20 is 0.64. Can machine stock T25 housings for a T28 chra to chase low 300s Should the hp bug bite, there are better options than trying to squeeze ...

holsets r unbeatable value. hx35 seem like the best quick spooling 500+ hp turbo for a street 2.0L. The magic is in the small runner divided header. A few crazy folks put holsets on 4AGEs. Stock hsgs r big heavy suckas tho an evo III 16g is an inexpensive, compact, light, responsive, tuff little bug...

SAFC work excellent with MAP 4AGE ecu. Should clean up a cammed up n.a. 4age fuel curve no prob Around here, used SAFC II(~$150) r like gold! As soon as they pop up they're gone Based on results, I can't think of a more effective valuable device for the money Years ago, a buddy fabbed a shorty heade...

oh i forgot to mention, cover any glass nearby when welding
masking tape on bodywork paper, then spray bottle water mist lightly
inside, cover dash and cut/wedge in cardboard to protect windshield. Spray mist just b 4 u start 2 weld

if it performs as good as it looks.... should go great! u gonna fmic or water/meth injection later ? r those custom headers ? tuned gze 'heat' r supposed to b harsh on headers. n e thing special about 'em ? this setup really shows off the charger, eh http://oldschool.co.nz/uploads/monthly_02_2016/po...

or... if u mig welding, practice a bunch of tack welds on scrap sheet metal then tack some pieces 'flush' on the sunroof panel, that will keep the panel from falling thru. leave the ground clamp on one. grind em all off later find any lightwt steel suitable sized to fill the perimeter gap. I sliced ...

single wire going to compressor clutch. +ve 12V energizes it Always 10" pusher fans I used to get from JCwhitney. Low cost, low amp pull Smooth silent run u could barely hear it run outside..... from inside a quiet car, not a chance Dunno whats out there now, as I haven't bought any fans for a ...

a fan on the ac condensor made such a big difference, I put one on all my old toyotas. With charge guages connected u could actually see the hi side pressure move, when condensor fan run My ac tech buddy even took out the little control box (mounted on the evaporator case underdash), and showed a tr...

gotta b careful modifying brakes. Systems have soooo many variables a simple difference in pedal lever ratio can make a world of difference, via stroke Our rollas split the brakes fr - rr. More modern pair the front left with the right rear on one circuit i just stuck to eclipse rr calipers on one c...

if the corolla master cyl fluid volume can't fill the rear chevy caliper, rears won't ever hold tight
an aftermarket prop valve won't fix or help that
I believe I mentioned in your rearend thread, about sticking with similar size/type import car rear calipers

sounds like u runnin chevy rear calipers.
Dunno if u can get the small import master + prop valve to "play nice" together
My buddy tried that mix-match n never got 'decent brakes'. Good luck

i can recall the thread about the CX cast manifold ending up with "good" turbo placement. From pix he posted, cleared the valve cover, dist & master cyl fine. That was the whole point of the back & forth excercise. Could depend on which T2x and how its clocked.... maybe ? ....or CX...

Turbo manifold DONT USE CXRACING/Ebay ones they break and fit like **** [$400+] I'm referring to the CAST $99 cx manifold. It was actually detailed on the old club4ag forum, how a 4agte user got CX to modify the flange angle so the t25 fit good Gotta remember MANY 4agte builds did NOT use a stanalo...

or put a bolt in lower tranny mount hole, with a socket between it and flywheel teeth

why complicate things with ITBs.... for so little benefit at lo output(if any) ? Get a stock gts rwd intake as suggested Tooooo many simple turbo builds documented, u can draw from CXracing (revised) cast manifold + used ca18 or sr20 T25 bolts on and is all u need gearbox could survive behind that t...

you really put the love in your project. Amazing job! I suspect you're not the lowered car type ;) I actually think these ride better, more comfy and quieter than the ae86 My hatch surprised a few with its stock 3T, moded 2T carb & exhaust. Ice cold ac (after tweaks) Too bad I lost photos of a s...

Those plug n play supercharger kits are nice. You can see where the custom parts drive the cost up Interesting d.i.y. supercharger miata installs exist, where they mananged to keep costs surprisingly low Built around used oem chargers + did their own fabricating + no CNC parts, etc.... Good planning...

only so much u can see of a low mounted charger with plumbing atop I reckon ? These miatas really show off their chargers, hot or cold side. Heck, rotate either 90 degrees and you probably had to cut for clearance. Then you could show em off with the bonnet shut :roll: https://farm1.staticflickr.com...

I had a 4AFE drinking oil, to the point it would smoke heavily momentarily. Everyone said oil rings, rings, valve seals, etc... On a guess, I disconnected the PCV from the cam cover(& rerouted to a can etc.). Never lost a teaspoon of oil afterwards Dunno if some internal baffle failed or what, b...

Besides, I didn't want to hide that beautiful charger away from view

No plans to install this powerplant then ? In a road car engine bay, it'll most likely hide from view

robust tq curve, for sure. Fun

I suppose the supercharger couldn't be flipped, so discharge on the opposite side ?
What sort of hp/tq/boost are your target ?
lookin good

u don't have to guess at your final diff ratio at all. As I did/mentioned, boro some old 240sx rim with a tall 15", or somethin
ez to calculate your ratio like that

What truth ? That it's not feasible to build a 250hp 10,000 rpm 1.6L 4AG to buzz around circuits for extended sessions ? So they suck ? Seems plain stupid to me, to use that criterion. What percent of 4AG enthusiasts fall into that extreme category ? 0.5% u reckon ? ...if that For example, look at t...

why cry? because some dude says a 4ag can't hang with 20 yr newer designs or they don't do what they were never designed to ? Big frickin deal what would u like a 4ag to do ? Carefully plan it, I bet it delivers, and at a surprisingly decent value Read the comments below that article. Some 4AG dieha...

I must say I really liked the 4.30 compared to the 3.73 gear, but that could have been partially to do with the 3.73 being open and the 4.30 being LSD. I'll have to consider making a change, the options I have are 3.91 4.11 and 4.30 which would you go with? if u preferred the 4.3 with your previous...

4.3:1 ratio fine for low tq revvin na 4age. Boosted motor far better off with taller gearing, in general Not only et better on the clock, but improves the daily drive..... keeps the motor in its 'sweet spot', less shifting, etc Same reason oem may run 4.10 on the n.a., but 3.7:1 on the turbo model o...

I wouldn't bother with head work/big valves = lousy bang for the buck. 16v head don't breathe worth a **** without cams n e way gze is a nice torquey platform to build on..... inefficient SC or not over the years, seen quite a few ae86 with 'upgraded' stock gze go 13.7s here is a basicly stock one g...

8.5 still too heavy. It's only a bluetop. Finding a 4.1 - 4.3 ratio may b tough Older s10 rears r smaller/lighter, close to same width. Should be able to find aftermarket lsd. Gearing, same deal. The one I have was like 3.3:1(fine for a turbo 4) As mentioned, custom(but cheap) disk brake conversion ...

classifieds have the heaviest traffic. Did u scout for a GTS diff ? I'd post the user name with a warning there, then reveal the transaction details if he doesn't respond.
