Just received a pm about this OLD link , so i thought i would up date it to answer the question .
UPDATED SPECS
Well heres as many specs as i can remember at the present time , might update it as there come to mind since its been over a year since i finished this conversion .
1.Toyota sprinter 1983{i think} , factory faded two tone,blue interior, 160.000klms old when i got it , one owner . It was one of maybe three silver and black two tones which was imported into SA as a ordering stuff up at the time .
2.Well where to start ? Maybe the front to back

5.Brakes , Car has had the normal toyota pug set up , to R32gts four pots using 16" wheels , now runs the best set up so far , S13 Sr20det sloted brembo rotors with R33 N/A calipiers with Special made pads . Nissan Master cylinder , wilwood bias valve , all new lines , Rear nissan calipiers 280mm rotors , modified commordore cup pads . 220mm drum , with alloy mounting . Brakes can out do the tyre contact easy .
6.Suspension , S13 front uprights , modified to coilover , change to height adjustable , Ex nissan works modified koni inserts revalved , fully adjustable , magic shocks . kings porsche cup springs , T3 camber plates special built centres {Thanks Gabe} Modified strengtened lower arms , Custom built whiteline bar {never again shit service} Modified toyota mx links , hard rubber mounts , Modifed caster rods {reinforced} Noltec rubber , Sway bar is removable without pulling the caster mounts off , strut locatation adds camber scrub with lower arm relocated 2.5>12' when full lock , relocated steering rack , modified turns lock to lock .

Koni Saab rear shock custom valving fuly adjustable , Custom whiteline roll bar {There mounts lasted one track day then bent } custom mounts made with rod joint link rods , 8 adjustment settings , king springs , All changed rubber bushings . Cars track has been increased to 1560mm , wheelbase is a extra 60mm longer . Cars ride is smoother than my stock one .
7.Drivetrain, nismo clutch pressure plate {came in the half cut} Stock clutch disc , s13 5 speed box , custom light weight one piece drive shaft ,tail shaft loop , to 7 1/2 "nissan lsd diff modified by 25mm {rear is soon to be replaced by multi link} Perfectly straight driveline , 3" pinion angle . tough never touched it .
8.Fuel system , Stock Injectors , malpassi adjustable regulator , 10mm new fuel line ,braided line, Custom sealed tank in boot , fully vented and self draining . Containing a one litre surge tank , large fuel filter , porsche rscs bosch fuel pump with intank vdo pump , modified pick up , fuel system design for 550hp so lots in reserve still . {soon to all be moved into the tank so i get the boot space back , and the battery into the rear quater }
9.Body / interior , Matt dash so your not blinded trying to see out the screen , Saas seats , two seat mounts , one fixed and one with stock rails only every fitted the drivers seat lazy i guess , Machined steering boss since i could buy one with the correct spacing , rubber autotechnica wheel i picked up of a guy walking down a street in the city one night {cheap too} alloy floor plate under pedals , Fully inclosed bumpers with fibreglass , undertray , ducted air box .
10.Tyres . rims , race tyres are a032r 205/50/15 On works rims 7.5 inch nissan 38 offset , as well as skyline rims with dunlop lm901 195/50/15 wets 6.0 inch ,as well as some dr30 rims with some crap kurmo rubber as the spares .
Future modifications taking place atm , well after 20.000ks of being turned up a 1.0bar the old turbo started making some noise . So it was out and a huge two days work it was replaced by a GTseries bearing unit . All the intake piping was on the wrong angle , the heatshelds need changing , the exhaust dump needed cutting away internally for the larger wastegate . Then the Compressor housing would have hit the engine mount when the manifold was at full temp , so had to alter that too . I will not even go into the braided "kit" which all the lines where the incorrect lengths and the connections would have leaked for sure . Yes i have a spot free garage floor and thats how its going to stay . So thats the turbo , now to alter the boost and check the a/f ratio when the dyno is free .
Tommorrow also starts the next major modification , and that is a bloody rear end with some traction . I have spend so much time and energy modifying the live axle to handle having stupid amounts of torque applyied with some luck , but not the the level i would like . Without going to a four link set up with longer arms to equal the loading the rear design cannot handle the levels of torque the engine is now . I have a custom diff jig and four sets of lazer cuts mounts for adjustable live axle rear conversions still , and a half finished half toyota/nissan diff but i am calling it a day modifying live axle , this is the only live axle car i have ever owned and it will not stay that way . So after having a sprinter half cut and a s15 rear diff dropped off , i did a wrecker search and measure and have decided to make a s13 unit fit with out body modifications , then change the geometry to specs like my bmw first .The main problem with the live axle is , it locking solid when the cornering force is at the level when the inner wheels on a cambered corner start to lift above the road surface , then break away is very quick !! Also the uneven torque loading of the force piushing the tyres to contact at speed like 160ish in the wet , this force being uneven produces the car to silde in the less weighted wheel direction when force becomes greater than traction . In short the car jumps sideways at speed above 160 on track in the wet when boost comes in .The front end turns as fast as you want to rear cannot keep up . Also might fit the oil cooler some time .
Current performance before the turbochange was
160-180rwkw depending on boost and fuel setting . Top speed 252klph , on g tech and the apexi rsm for standing start{no stupid drag launch} has recorded 0-100 below 5 seconds , quater mile { not interested } and gearing is to high really .Fuel usage is 220ks per tank on the track , but once did 600 per tank easy driving , lap times have been ok{mostly in the top ten}once third in the wet , but the extra traction would improve that lots . Has left gt2 - gt3 - f360 challenges and lots of $250g+ cars for dead , car to beat would have to be the avo's s14 , evo r s15 , only once been quicker than the s14 , the 500hp s15 is far ahead in straight line speed but easily catch it on corners . Might turn the car to a total track car sometime soon .

Very nice dude. Aint the plumbing from the cooler to the throttle body a bitch?  What radiator did you use?
You iwll love it once it is on the road, trust me! Mine goes like stink 
If you want to see pics of mine, they are here http://www.pbase.com/sr20ae86
Good to see someone else has seen the light and gone SR, but glad glad I was still the first (as far as I know)
Cheers

Nark . Thanks . The tanks holds the secondary 550hp pump { for later turbo upgrade } ,filter and one litre surge tank , all the fuel lines new 10mm size . The box is sealed , vented and drains back to the tank if a line gives way with 80psi of fuel .
Bassaholic55 . Thanks it took three month of weekends , was going to have six months off to finish it but had to go back to work .
Statts . Thanks . the radiator is a custom one , double core , triple bypass , 1125 cfm twin fans, the photos are old now its changed a bit now , Yer they go ok , but the performance is much better after fitting a 3.9 ratio geared diff for street ,and 4.1 for track . How did you get the correct tailshaft angle with the gearbox that low ? I had to change the floor shape to get the tailshaft level with the car 2,1/2" lower . How did you go with the enginneers or is there different rules in your state for the filter being in the engine bay and a non factory ecu / manifold and the catcher can . I bet you would have had fun fitting the engine without making the radiator panel bolt in . Did you fit the a/c to ? And wheres your bov , mine is upside down before the cooler . There is another one in sydney and sa somewhere . I don't think we where the first .

My tailshaft angle is fine. No problems with it hitting the floor and my car is roughly 3" lowered. My car is not engineered and wont be unless it has to. I didnt have any trouble fitting the engine and gearbox as one, without removing the radiator panel. Didnt even drop the crossmemebr on its bolts. Didn't fit the a/c, thats not too important to me. Am not running a blow off vlave at the moment, just adds to cop bait, I may add one when my new turbo arrives, if I do, it will be a GReddy Type R plumbed back into the inlet. The only other one in SA apart from mine is a non-turbo. Oh well, even if we weren't the first, we still know how to make Hachi's go quick

EVOSTI . Yer the a/c isn't that hard due to being on the same side as the 4ac , the outlet hose has to be about two inches longer just that toyota's and the sr's don't have elec engine fan which has to be turned on with the a/c via the ecu . Due to the stock sr fan being so high compaired to the radiator airflow . The Toyota compressor switches with pressure and the nissan having climate control to control the compressor that fun to work out ,with external and internal temp sensors for the nissan .To make it work in two modes like the standard Toyota a/c takes while to get as good as the factory Toyota air .

I have a question for you guys about the engine mounts. Do you have to make up custom engine mounts? Any info you can give me about mounting the engine would help me a lot as Im going to be douing this conversion soon.
Cheers

The way i went was to get rid of the expensive nissan mounts that break all the time and are $200 each second hand . The main difference is the mount angle , i think the toyota mount are on a 60' angle and the nissan mount are at 45' some you have to adjust the angle of the mount on the subframe and the centring of the engine due to being to high if mounted straight onto the toyota subframe , as well as to forward to get the centre of gravity back to about 53/47 on my car with the steel panels . And i made the mounting space so i can use bmw 528 mounts , or a six cylinder toyota 6 cylinder mount they break . How many s13/s14 do you see with a extra mount to the side of the cylinder head , and those stronger gearbox mount . If nissan engine mounts where used in a sr20 ae86 you would be able to get the turbo / inlet to hit the strut towers with some hard driving . Gearbox is a made mount , the easy part .
King16
I don't think anyone does the a conversion kit ? The main cost would be the wiring if you where not going to do this yourself , there is a lot of work here if you want to get it engineered due to having to get all the emission gear to work correctly ,as well as the speedo to read the correct speed and the check engine light , cat overheat light to work . get a speedo to work with the stock sprinter guages could be don't i guess by using a vl/skline r32/r33 gearbox , electric sensor to cable conversion kit , then just get the cable made to suit .
Cost i have spent $8g including paying alot for a good half cut $3.5g ,engineering will cost you if you don't have a mechanical engineer as a friend , put still there are only about 12 of them in victoria and most will still charge about $1400 to $1800 after all the bullshit tests etc . Or just have it as a track car . Ask Statts if his work will do it for you , since they have already gone through all the trouble in this conversion , or just buy one when they get sick of it . Yer right .
