M24 [SR20DET] turbo VS VF10 [Legacy] turbo

[l1ttle_d3vil]

Looking at aquiring a turbo for my 4age.
Not wanting a huge amount of power; pretty much as much as possible for the least amount of money as possible.

There seems to be quite a few VF10 turbos around for decent prices; ive been told these are suitable. Would these supply the best amount of grunt for money?

Also been told M24 turbos off sr20det's are really good; how much better are these than the VF10s? and what sort of price difference would I be looking at between the two? is it worth it for what I want?

cheers.

SR20DET's came with T25's and T28's.....

thats what i thought. id go for the t28 bb

[RS13]

Depends on the model of M24, they came out on VG30DETTs' mostly, as well as several Nissan diesels, both of which are too small for a 4AGE, I'd say. Apparently Garrett did make an M24 as a replacement to the Nissan/Garrett T28, the later M24's are ballbearing, with an a/r of 60.

Although, I'd go for the VF10, they're cheap as, and everywhere. Nissan turbos are getting pretty pricey, due to everyone wanting to slap one on their CA18, lol.. but then, if you want something cheap as chips, I'd go an RB20DET T3-style turbo, they're ceramic, and can't handle much over 10psi, but they're so cheap its' not funny, as everyone seems to swap them with something stronger!

[l1ttle_d3vil]

apparently the M24's come off non gtir sr20dets...thats all I know about them, and that they are hard to come across.

ive done a search on trademe for the T3 and the cheapest ones on there are about $500 all the way up to $1200. not quite as cheap as all the VF10s on there which are around $100+...

keeping in mind that I don't want a huge amount of grunt, so I end up blowing diffs and gearboxes all the time. I'm running a T50 but it won't be driven hard or anythin, just the power on in a straight line not a heap of skids or dropping the clutch etc. in that case, the vf10 sounds like it would be the best bet so far...?

I've never seen / heard of an M24 coming from an SR20DET. You either get a T25G, T28 or T28(bb) on non-GTIR SR's. T25 turbos come from CA18DETs.

What's wrong with that

it was referred to as an "m24 t25g"...sorry; thought the t25g was irrelevant my bad

[bluemaumau]

if you wanna go vf series go vf8 as its apparently just a little bigger

[Caveman]

vf10, t25 and td04 are all pretty much the same power wise. 52mm compressor exducers. The only difference is flange and maybe a difference on spool time.

I would run a vf series cos then you can bolt on

vf10
vf8
vf22/24/etc/etc
td04 - subaru only
td05 - subaru only
vj22
+ most other turbos by IHI

They are the same manifold and dump pipe flange. basically direct replacements.

Yeah,

as i have said to you, the t25g (has m24 compressor cover- some of these people have never seen one im guessing, they dont have t28bb written on them) will be better, full stop, however is more expensive and harder to find.

What i said was, if you run vf10, it will spool slower, but have a slighly better top end.

However, id rather have the early spool up, as i have to hold my clutch in for ages to initiate a slide.

bigger than what?

I will probably go with a VF# turbo then...due to the availability and cost of them in relation to the others; and also the number of other turbos compatible with the flange.
so which would be the better out of the VF8 and VF10? what are the pros and cons of each?

[bluemaumau]

vf10

[Caveman]

VF10 has p15 ex housing which is smaller and spools quicker but chokes the engine at high RPM (ralatively speaking)

VF8/12/22/24/etc have a p17/p20 housing which is bigger. It spools slower but the engine breaths better and makes more power at high RPM. All these turbos have bigger compressors than vf10.

vf10 will probably peak around 250BHP

td04 arnt a bad turbo for small power. The flanges are also compatible with td05.

i'd run a vf8 over a vf10 for sure...

i run a vf10 on my 4k and it spools by 3000rpm so a vf8 will be sweet on a 1600 twin cam if you make a decent flowing manifold

yeah yours has smaller ex housing tho?

Run vf10 or td04, i havent seen a vf8 for sale in a while. Vf10's are like 80 bucks, you cant go wrong.

choking the engine relatively speaking 1998, is like saying petone is further from auckland than lower hutt. The difference in top end wouldnt even be noticed on a dyno i presume, the difference is more legligible than between a 200km stock bluetops power and a 250.

vf10, less taking more doing

if that is the case I would be more inclined to run the vf10 then.

also i just searched trademe for a vf8 and it came up with nothing, when there were about 6 vf10's on there lastnight.

so, choice has been made - I will run with a vf10. thanks for the input guys; keep an eye out for my next thread cos there'll be more!!!!

[crnkin]

just turbo it, no need to keep asking round here.

Make your manifold, bolt it on, run the oil lines, plumb up cooler, drive. simple what else is there to discuss?

do it

Yep i know its not very much, There is however a difference and he wanted to know the difference.

however a vf10 will choke relative to a vf8, although its not very much its something to keep in mind when going for peak HP.

Thats why a vf8 vs vf10 at same boost, the vf8 has better charge temp and less restriction on the exhaust therefore will make more power.

The trade off is the vf8 is lagier.

Its up to you to decide what you want.

The last vf8 I saw on trademe went for $150.

cheers for pointing that out. im not going for peak HP that I can get out of the turbo or anything like that; just would like a bit more grunt that pushes you into the seat a bit more.

[terola]

ive got a complete vf8 in whakatane. if your keen. and a vf10 aswell actually....
