Looking seriously at the SR20DE VCT S14 conversion. Need to stay NA.

If I don't have power assisted brakes, will this engine slide in the same as a SR20DE from a S13 silvia. Any tricks I need to be aware of. Will a stumpy gearbox bolt up without modding the clutch etc. Can I still get away with no firewall or trans tunnel mods.

Have tried search, but can't seem to find the good threads I have read before about the SR20 conversions, any links would be greatly appreciated.

Cheers
Damien
ps. How much extra weight in a SR20 compared to an A15.

Yes all SR20 motors bolt in the same way. The differences are in the accessories.

The stumpy gearbox needs to be modified, by removing the FJ transmission front case, and bolting an SR front case to it.

If your 1200 is an automatic (3N71B) model the transmission 71-series manual will fit.

The SR weighs approximately 50% more than the A14 engine, 149kg vs 93kg. Ditto for transmission 70lb vs 100lb. And for rear axle.

Damien,
There is a wealth of info around the net.
SR20 VVL engine is the one you are thinking of, which will make searching for info easier.
Problem with VVL in RWD is the Distributor and VVL solenoids are on the back of the head and both will need to be relocated (i.e you can't run a distributor, you will also need to find a new CAM/Crank reference point for the ECU, although I'm sure I have read somewhere that people use the distributor hole as the CAM sensor pickup). Not sure if Nissan did a non-distributor version of the VVL engine?

The FWD SR20/SR16 blocks have a different gearbox pattern which makes it difficult to adapt to a RWD gearbox, however the RWD gearbox will bolt up the RWD block. You could use a SR20 box with min modification to the trans tunnel (to be honest the trans tunnel mods would be the easiest out of all the things that would need to be done).

weird that fwd have different pattern to rwd for the bellhousing??!!

I'm told the s13 de has alot more tuning capability and is the pic for na sr's if wanting throttle body's and so on. I'm no expert on this motor but have had it agreed with several times from reliable people . I've also seen a few na vcts with vct solenoids actually disconnected. Something to do with better head flow on the later models

Your biggest issue will be with the VVL solenoids and Dizzy if you do not want to cut the firewall.
Mounting a RWD 200SX gearbox to the SR20VE(only FWD) is no big issue, get a SR20 RWD upper oil pan etc and all but 3 or 4 bolts doesn't align, take RWD flywheel, machine the lip between block and ring gear away and you can use the FWD starter, Then get a SR20DE Pressure plate fitted to the flywheel.

If you are looking for a bolt on conversion, stay far away.

Look at my project thread, this is a crap load of work, but not rocket science.

just use a s13 sr20. theres not much difference at all between the the two, you don't really need vct and i also heard the "vct rattle" is quite common and its a nice enough touch but it really doesn't do to much for ya.. if i will go vct the only reason is that its a newer motor with low KMS which will probably come from a S15 so it has vct anyways. If you find an Autech sr20 from an autech s15 then even better, its a 200hp motor factory autech tuned.(i see they come into the car auctions now and again written off with P plates).

Theres alot of info on the net everywhere. Quad throttle boddies are possible, ive seen them in a coupe and the kit is from efi hardware, linkages and all. you just need injectors that plug straight in and aftermarket ECU. one of my future mods ($$$$).

you need to think about your rear end... R31 diff, remachined tail shaft to suit etc. whatever your wanting to do, keeping drums or go rotors?

firewall doesn't have to be pushed back but its a tight fit! trans tunnel is a must do. I forgot his name but theres someone in brisbane near ipswich that does crossmember kits that use standard s13 engine mounts and firewall isn't required to be cut out and modded.

then suspension/brakes to handle the extra wieght and speed. Maddat SR20 sway bars are awesome and well worth the cash

i went s13 sr20de. cut tunnel , r31 lsd shortened rear end, stanza struts n brakes up front, maddat brake booster. maddat sway bar, custom engine mounts and crossmemeber (would of been easier to go maddat premade) im running standard ecu and throttle body atm. eventually gunna go s15 vvl once this gets tired.
lots and lots of info out there , and heaps of builds on here if you get stuck :)
costly build is all ill say haha

Is 36 HP "not much difference"?
