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.

      Like I said, "black magic" LOL In the end,  it is what it is, and hopefully, what this here knuckle head has done is an improvement and not a hindrance Not that I actually notice any negatives now, or that I will get any seat of the pants benefits when all is said and done, but best practice says I shouldn't be pulling intake air from the hot engine bay  Famous last words: I cannot see it being any worse than what it is at the moment 🤔

      If the gases flowing in those two tracts had the same properties, you could maybe use such broscience. But the exhaust has a different composition, different normal density, different actual density (because of different normal density, and mostly because of the massively higher temperature), and different viscosity (again because of much higher temperature). Consequently, all of the fluid dynamics parameters that matter, that you calculate from these inputs, such as the Reynolds number, friction factors (for wall friction) and so on, are all incomparable.

      In the US almost everything is E10. It can't exceed 10% by much or fuel systems have trouble adapting. At the same time because MTBE, MMT, and TEL are all banned they need as much ethanol in it as possible to boost octane.

      I was mostly jesting. In my experience (and probably only my experience) the R34 GTT physical airbox space is actually too small to flow the amount of power it wanted. By sealing the box, I made it so it could only be fed by the ducts themselves. So you can seal it up and get nice cold air which IS good, but at a certain crossover point: More Hot Air > Less Cold Air I don't think you're at this point. In my case merely ducting the hot air intake with a very focused set of ducts counteracts the fact it's in a V8 engine bay. More cold air obviously best. The solution looks great.
