i am currently doing this conversion and am using a r32 cross member and planning to use vl engine mounts??

will this be suitable and will the stock bonnet close with the motor in???

also i will be running a rb25 box and i have bashed the tunnel out so it fits, does anybody know if the shifter will come out the standard hole???

thanks for help..

your kidding? its fits with standard, mounts n shit? sounds a bit odd..... its a very tall motor in a very short car....

+1 My 33 surely has a taller engine bay and the RB30DET Just fits in i think the cam gear cover rubs the sound deadener

The workshop whi finished off my car, had an S13 in there getting some work done it had a 4L in it and required full custom engine mounts to sit the motor quite low in the car, would a S13 be simmilar size in the front?

we will see in 3 weeks if it fits... if not i was given another combo, r33 x member, rb20 engine brackets and rb30 engine mounts... if not i must use all this and space the x member 10mm lower for clearence for teh stock bonnett to close... s15 has a fairly decent sized engine bay... id say close to a skyline..

poeple hav fit 26's into them no worries, so we should be able to scrape 38mm somwhere

When I did my conversion, the RB20 and Rb30 engine mounts/brackets looked identical..

thats what i was going to say there are some slight changes but general fit up the brackets are the same across the board, RB26 is preety much the same as 25 height wise that extra 38mm is more than you would expect

I guess its just a case of siting the motor in there and finding out for yourself but i reckon you will be doing custom brackets which is not rocket science for some one handy with a welder

just out of interest what do you use the car for?

if it fits under the stock bonnet, I reckon the sump will be dragging along the road... or at least low enough to the ground to be of concern.

Was that the VH41DE? If so its good to know that it can be squeezed under stock bonnet? Every one I've seen has had a hacked/custom bonnet

A mate of mine has fitted a 1UZ-FE 4L toyota V8 under a stock S13 180sx bonnet, without the crossmember being spaced down, was a hell of a lot of work to make the sump work

Always wanted to do a VH41DE 180sx(keep it in the family lol)... but mate has easy access to cheap 1UZ-FEs and if its possible... :)

its abit late now, the motor is prertty much built...

car will be used for drag and some street cruises, not a everyday car may see the road once a week...

im unsure of your comments as ive spoken to afew people that have done it and they say it does fit.... i guess there is only 1 way to find out... also the sump is custom so it wont drag on the ground...

sofar i have put solid steel spacer plates inbetween the cross member and bottom of the chassis which are 10mm thick, hopefully using the brackets ive been told to use will help, but if not it will have to go custom brackets, im not changing engines, sr20 are shit, thats why i threw it away.

      Not that I know from experience, but in theory you'd want your gate spring to be as close to target pressure as possible, so you'd go with the higher gate spring?

      Before I commit to it as I already have the wastegate off the car, would you change it to the 9psi spring instead of the 12, or whack it back on now and try your suggestion?   Edit: Actually I might just swap the spring and see what the logs say after another few pulls, as we know it's still spiking without the Mac valve in the picture so I need more data without the Mac valve trying to combat the issue.

      Sounds good Hmm suppose the main thing is, how much do you care about this car? The filler doesn't make for a very good water barrier lol. If there was a tiny little bit of rust forming now, that in 3 to 5 years time becomes obvious under the paint (starts to bubble up), would it bother you?

      Mistakes were made, my R34 Story

      I already have the ability to datalog the voltage... what I can't do is correlate it to what the gauge is showing when I'm looking at the data at a later date. Or something like this. Except getting the oil to 125C+ involves me going 200+kmh at the track so you can imagine this is a little tricky unless I do something like note what the voltage is when I am at the top of 5th gear so I have a point to reference on. Drove car today. O2 still reading richer because hopefully not a leak instead of massive restriction I've introduced. Car really doesn't sound like a LS. It's quite strange. Pulled a bit of fuel out up top. This does potentially explain why my spark plugs looked like the car was running pretty over-rich. If I was tuning it to a ~12.7 which in reality was far richer than that in the past. It will be handy to have the dyno WB to compare my WB to to compare notes that's for sure. At this point I'm happy to just sit in the passenger seat and tune the thing given I've got about 7 million hours on the platform lol.

      Yeah I understand you have to pay for an updated map or subscription service or something. But I can't even find a current map for Australia. My map is dated 2017, but didn't this car version still sell in Australia until 2021?   Also, just as an aside, the navigation system warns you of traffic incidences ahead.....why would they include that on a map they knew is not receiving live information. I am forever going to be warned of an incident that probably existed for 30 minutes 8 years ago.
