If you only want less than 200rwkw (I say only, cos although it's still damn fast...lotsa people on this forum are well over 200rwkw) I would stick with the SR20 engine. The SR20 is a very responsive engine. Just need to pick a correctly sized turbo, and for around the 200rwkw mark I would go for something like a GT2530 or something. Should be able to hit the mark on a bit over 1bar, and not much laggier than standard. For a bit more power, but more lag...go the GT2835 which is supposed to be damn nice for the SR20. Any larger and I reckon you won't like it as it's too laggy. Also, the TD06 can be a nice equivalent too.

The biggest problem for my swap was the wiring. The diagrams that I have showed r32 and 180 have very different wiring setups. Once you find all the powers and grounds and get all the relays working you shouldnt have a problem.

PS I would go with custom mounts rather than the r33 x member so the engine will sit down and back a little more.

should be able to hit 12's without a problem cuz mine has a rb26dett and it runs 12.3 @ 118mph with upped boost but dont forget I have 205 street tires and no lsd.

RB20DET deck height is considerably shorter than 25

RB20DET does not need modified mounts in S13, RB25DET does to enable the engine to sit lower so the bonnet can close.

RB30 deck height again is taller than 25

well if you dont want to butcher your bonnet use custom mounts.

he clearance for my bonnet is a fair bit.

do it which ever way you choose to. both work.

as for weight balance, throw that out the window.

speaking from experience having a light as end, is all the fun. just dont get silly in the wet.

Excuse me? You've weighed and driven RB20DET and RB25DET equipped S13's?

Didn't think so.

The RB25DET is only slightly heavier than the RB20DET, although it is a far superior engine in most ways.

Perhaps you should question what you have been told by dickheads who dont know what they're talking about and dont repeat said rubbish by passing on your 2 yen.

I didn't modify my engine mounts and it fits just- gotta custom plenum :)

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      R32 gtr transmission strength, billet plate

      By cosline · Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
