Turbo Y4

[Lukezen27]

honestly if any1 would want to run 10-20psi on d series vtece or non vtec i think all u would need is

CP Vitara pistons (76mm)
-Wrist pins and C clips
-Piston rings (Hastings or NPR)
-Timing Belt
-Water Pump
-ACL Rod Bearings
-ACL Main Bearings
-ACL or King Thrust washers

and for turbo BULLSEYE-POWER/BORG WARNER T3/T04e 57 trim

Most of us know exactly what's needed and how to buy those parts you've listed...

Its the labor that's the killer IMO

tbh if u know what to do it wont cost alot might aswell do it right the first time not second

Straight plug N Play too, install that day boost that night

Only real mod needs was the oil pan drilled

Stock 240cc injectors were fine up to 120kw

at that rate, id say the stock injectors would be near maxxing out.

Even i know, the most weakest link in a d-series engine, is in fact the conrods. alot of the US guys use eagle, & i know fjt has manufactured some custom length ones to make up for the low compression height of the vitara pistons.

Well I'll race any of em at the Creek...

NO MATTER what you do or how good the gear is SOHC power sux till boost so you don't move before 4000RPM

N/A Honda's with 20kw less power would smoke me

I mean don't get me wrong, I loved boosting round in my little D-turbo

With such a small turbo, i should be in boost almost all the time im driving. it should hold good til redline aswell. i rarely take it to redline, 6k max...

u should of did abit of work for the internals would of had a beast of a single slammer

If it blows, then ill go all out, fact is its my first turbo setup, i wanna go easy on it. after all, its me daily & the misses drives it aswell. i dont want to take it to its limits.

hey i had a T25G on mine and swaped it for the GT28R turbo personally there was a vast power improvment just from putting this turbo on and would recommend spending the extra money on getting a good turbo.

what manifold do you plan on running?
i have a New AFC Neo F/S if your still chasing one :P

I think many D16 manifolds will be for a T3 flange.
Edelbrock would be one the few choices with a T25.

I think the slightly shorter VTi Y5/Y8 gearbox plus a LSD should be at the top of the list.

Save some cash. Go for the NGK copper plugs.

Salvage one from a late model, performance oriented wreck.
Bound to be some smashed up v8 commodores about.

Fair choice.
T28 wouldn't go wrong either.

If you gonna boost it soon, why service it now?

c'mon, harden up.


1) Look for other posts on here or d-series.org about shimming the oil pump.

2) A morosso series 2 oil accumulator is cheap insurance.

3) If your ignition system is still original, it's probably a good idea for a new dizzy. No need for an upgrade, it's just an item which needs replacing and it'd be a good time.

With a good, straight through, rear muffler, and low boost, the stock, cat back, exhaust pipe should be an ok compromise.

A 2.0in pipe will flow 280cfm, which is just shy of your goals (150Hp = 330cfm). You just need to make sure the muffler itself isn't the choke point.

What's the inside pipe diameter of the cannon?

Nick.

OK, ive seen a few ebay cast iron manifolds which claim to have T25 flanges. i could also get a mild steel log mani fabbed up for relatively cheap i hope.

Out of the D-series g/boxes, the Y1 has the best short gears. i want to stay with the Y4 box 'cause i know there's plenty out there to be had. ill be changing alot sooner anyway with boost...

Thanks, ill keep the copper plugs in mind. is there any particular reason why these over the iridiums?

I do also plan to change the dizzy to a new OEM unit. i'd have piece of mind knowing the ignition is working at its best.

right now i have a 2.25" press bent mild steel catback exhaust, 1 resonator & the cannon muffler. i pretty certain the inlet on the muffler is 2.5", though i could be wrong. Do you suggest getting a cat from a V8 commo, or would a V6 cat work just as good? Id much rather use mandrel bends for the exhaust, & since im going to that length may aswell change to 2.5"...

ive been trying to find info of your setup to give some pointers. I actually have a few manifolds in mind. first choice would be the edelbrock cast iron manifold from the kit, second would be a mild steel log manifold, 3rd would be an ebay cast iron unit. If i can get someone local to fab me up a log mani, would much rather go that route, instead of buying the cast edelbrock unit & paying through the roof for shipping. if i can get a log mani made for around $300...

Im still pretty firm on the T25G, im sure the GT28R would be a huge improvement over the T25G, i can get my hands on one for reasonably cheap, im sure ill be happy with it, afterall, itd be a much better improvement compared to a stock Y4, right???

[na-118]

any ecu with this basic setup, looking at doing one just starting on my research now cheers

[MikeyG]

best ecu would be s200 or s100 or even proecu its all about tunning

[MikeyG]

btw is there a shop in aus that sells eagle conrods by anychance?

[Lukezen27]

Look for a GReddy Log Manifold off (EG Civic 92-95) turbo kit

That's what I had they T2/T25 flange

[hisoka]

Yeah but the power brand sux on SOHC Turbos IMO

I thrashed mine for two years and 1/4 miles her heaps but never got any good times due to power lag

what turbo were u using again.

EDIT. dw lol just read

There prolly wont be any info on my setup caz i have never put any up but basically i had a T25G and even these on a SR blacktop would boost up at about 2200RPM and our motor is smaller so i would get full boost about just under 3000RPM mark i am now waiting a few hundred RPM more for the same boost on the GT28R but it hits alot harder than the T25G although it was a good turbo and you will be happy with it.
just make sure that its in good condition with little shaft play and if there is any end float just look for another one, they usually sell for between 200-350 mark for a good one.
My manifold is a custom made steam pipe manifold i would recommend these as they dont crack, but for $300 thats pretty good price and would just run with that for the moment.

run with the 2.5 inch and get a new high flow cat i get the magnaflow ones for about $260 brand new they have a huge CFM rating rather than a stock cat from a commo those motors are dirty same with the falcons and i know some tuners that put them into cars to get them through emissions because of that. the 2.5 inch resonators are different in price in regards to how long they are abut range from 80-100 or so and you can reuse your cannon if its a 2.5 inch inlet
most of your power is going to come from your exhaust after turboing it.
