late 97 on hilux 3rz turbo conversion walk through

[BeRad]

They can be made to rev, but where do you stop spending thousands haha, unless you spend money on cams etc, there power curve flattens right out around 5500rpm, wont lose power but wont gain much more, it is more than achievable in the scheme of things but the driveline and fuel system to support it would be a HOMO to drive around the street especially if in traffic

Trouble shooting.
Ok when i start it up cold in the morning 5am it has its usually sputter and tantrum as its cold whihc i understand. I get to work (30mins park it up (let it idle down) then wont see it till 3pm that day i jump in start it up and its got a bastard missfire on low revs. tho after it gets hot (with in 15mins) its ok. At high revs its all sweet aswell.
Iam thinking sparkplug is fouling or a dodgy sparkplug lead.

[BeRad]

or the coldstart compensations are totally wrong, or inital start fuel prime is way to much, a properly tuned ecu shouldnt cough and splutter, hard to expect it to run like factory but should be pretty good, do you have access to the ecu, post what the water temp compensations are at what temp.

A dodgy coilpack had the same effect on me until it got worse and misfired thru the whole rev range, pull a lead put a old plug on it and compare the spark from all 4 see if one is weak, but yer all of the above could contribute.

It didn't do it after the tune up it ran fine. Also could be bad fuel as i keep thinking it happened after i put a tank of fuel in it .
I'll start with basics first spark plugs and a fresh set of leads

[BeRad]

yep, bad fuel fouls plugs, takes a good thrashing to clean them, but thats also not good with bad fuel haha.

Just drain the fuel, put new stuff and clean the plugs, 30 mins work, or ill do it and you can rebuild my front passenger brake right now haha, goes on a 3 hour drive at 5 in the morning and i dont need a broken brake and boiled fluid haha

Some info regarding the r series box to 3rz...

http://www.opw.com.au/ --- Is the Aus dealer for marlin, im unsure on their markup, it may be worth directly importing from marlin.

http://www.marlincrawler.com/transmi...on-bellhousing

marlin make a 3rz to "R" series bellhousing to suit any r series, the only difference between them is input shaft length, spacers are included to fix that as im sure youll read, marlin crawler is the ducks nuts as far as quality etc go in the 4x4 world so theres no hassles there.

If your keen to go down that track let me know, n postage should be minimal as a mate has a container leaving from california in about 3 weeks now, bound for brisbane.

as i said on the phone, the ifs model turbo diesel surf's have the r150 box behind them, you can buy a whole car that is usually running for 500-1000. The gearing options are endless, in stock form the gears are higher, so gears/diffgears etc might need to be played with as it finish's the 1/4.

The following info came from the below URL, ive taken most info out that is relevant, but has good info in there.

http://www.jeeps-offroad.com/f41/eng...housings-4740/

early r150/r151 boxs have a input shaft length of 6.5inch, identical to g and w series box's.

ALL Toyota R150's and R151's built before 1996 are SHORT SHAFT\SHORT BELL. These CANNOT be used in a LONG SHAFT\LONG BELL application or with LONG SHAFT\LONG BELL adapter plates.

Trans gearing as follows
R150 - 3.83 2.062 1.436 1.00 0.838
R151 - 4.31 3.32 1.52 1.00 0.83
R154 - 3.25 1.95 1.30 1.00 0.75


This info applies ONLY to the AX15 and R150F. (AX15 is a jeep gearbox).

"Parts are interchangeable between these trannys. Inputs, output shafts, front nose cone, and rear housing are different but generally can be interchanged if you stay with in the family.

There are three "R" families;

86-91 early, simple, common, heavy design (rated to hold around 40% more torque than the w56)

92-95 upgraded syncrows, hubs, shift rods and linkage, smaller bearings, lighter gears

96-newer greater helix angles, upgraded syncrows, lighter bolts, reverse brake

It is possible to swap the 91 and earlier Jeep (AX15) input shaft into an R150F and use the Supra Turbo bellhousing to hook it up to the 7MGTE. However, this shaft swapping can be avoided if using the 1996 and later R150F which has a longer input shaft already.

Just some useless random interesting info, i have no idea what a dakota is???? but using that bellhousing will mate the R series box to any 3.8 como motor.

ive added a turbo, but theres several standard toyota blowers that can be added, and retain the stock ecu, saves you some money if you just want a little more power, but obviously limits you. the stock ecu will not suport a turbo even on 6psi. stalls and pushs massive amounts of fuel into the engine.

firstly i have to say great thread. plenty of great info in here.

any idea why the stock ecu will handle a blower on low boost but not a turbo on the same boost? i would have assumed it would run both or neither.

Anyone interested ina group buy for the r154 to 3rz bellhousing?

[rodi]

why doesnt someone make up bell housings to fit T61 commodore boxes, way cheaper and available

[Tweak]

pretty sure lcracing has made a few adapter plates for GM transmission

Anyone interested ina group buy for the r154 to 3rz bellhousing?

get a 2.7vvti bellhousing and make up a 32mm ally spacer.

[Tweak]

isn't the shaft length a problem and also the cluch fork?

[Tweak]

would be great is marlincrawler's would bother to respond to emails........ FFS it wen to 3 of there sales guys and not one of the fuckers has bothered to respond.......... Piss poor customer service. I'll spend the money on a arb air locker instead

[rodi]

I've started work on an adaptor to fit the 6 speed commie box to a W series bellhousing, giving 85 kph in first @ 6800 and a top speed in 6th of 477kph

[brett_celicacoupe]

isn't the shaft length a problem and also the cluch fork?

fit a straight 32mm spacer between gearbox and bell = shaft problem solved

extend the throwout bearing carrier by ~25mm = clutch problem solved
