SR20DET Project (It's actually going in a 200B)


Recommended Posts

Nice.

 

Is it going to be a sleeper or all JDM spec?

Sleeper even with stock hupcaps :)

Very cool. IRS rear end or the railway sleeper of the later model 200B?

This one has the non irs :( i have read you can convert)

 

Check out engine test fit pics below. I also heard of people using R31 or S13 engine mounts but i tried it with the stock 200B items.

Should be a bit of fun  :D  I fitted an inexpensive 240Z coilover conversion to the front, an s13 sway bar to clear the sump (which requires a modification to the front chassis bracing) and i'm using 200B hubs with Modified 260Z discs and S12+8 Toyota Hilux calipers.

The transmission crossmember is the 200B centre with S13 ends required to position the transmission mounting point back 20mm.

Awesome project. My first datto was a very mint 180b station wagon with the SSS carbs  - sold years ago, but I really want it back! (anyone seen reg IKZ-479?....)

 

The SR20 looks a really nice fit in there!

 

How hard is it to get something like this registered? I presume that's what the brake upgrade is for.

Not sure on the legality of the conversion but i'm doing the whole package so it stops and handles as well as it goes.

 

We only just registered the car a few weeks ago and then fitted a downdraft weber and electronic ignition. It blew the head gasket not long after. We added up the bills to turbo the L- Series and decided the SR20 was a far better option.

Yesterday was a busy day, parts arrived tuesday which gave me time earlier in the week to finish the brake setup. I ended up using modified 260Z discs and hubs but i want to change to 240Z struts on the front to fit the bigger disc.

 

The standard 200B discs are 245mm diameter.

 

The engine, gearbox and 30mm shorter tailshaft are now fitted. The stock clutch slave cylinder bolts straight up and as you can see the shifter is not to far off from where the stock one protrudes.

Honestly i can't take all the credit, these 200B's are nearly perfect for this conversion.

 

The intercooler, intake and and blow off valve only require two fittings (in transit) to be completed. Next stage will be the wiring and i hope to fire her at the end of this week.

Looking good Mark. With the break upgrade, are 200b hubs the same bolt pattern as zeds and do they take the same bearings? Just thinking, if they are the same and have the same 25mm hub face thickness then these could be used as an alternative to 260 hubs for the magna & 12+8 vented upgrade....

 

Also what sort of spring rates to the coil overs come in?

The bearings are the same, the hubs are slightly thinner and the same bolt pattern (i'll take a measurement and report back). Spring rates for the coilovers are 5Kg front 6Kg rear.

 

I'm just finishing up the little jobs now.

That will be a great Xmas present for the owner,  perhaps you should deliver it in a Santa suit  ;D

I'm grey enough in the beard deparment but not nearly fat enough  :P

 

For the last few days i've been doing some product testing and development  ;D but had an issue with one of the intercooler pipes blowing off just after i had the 3" mandrel bent exhaust fitted. I limped her home and fixed it but now a couple of days later she has developed a misfire.

Sometimes it will fart and pop then all of a sudden it gets a huge surge of power like it has a rocket strapped to it. List of mods is as follows

 

Black Top SR20DET

Chrome Moly Flywheel

GkTech Exhaust Manifold

S15 GT28r Garrett Turbo

Adjustable boost

Commodore fuel pump 70psi

3 inch mandrel bent exhaust

Front mount Intercooler

 

The car still runs the stock ecu which we have a Mines ecu on the way to replace.

 

It only started running like this when we put BP 95 in it but i'm just seeing if anyone here has any hints before i go chasing the issue. I am thinking i fouled the plugs when she fueled up!
