Suby-conversion advice?

Last Triumph · #1 September 27th 2006, 07:06

Thought so - I don't mind paying for a G50.

A 200bhp pro built type one motor is £6k minimum + trans

A type IV even more + trans

A V8 small block 300 bhp 'turn key' crate motor £5k + trans

A Sti Scooby 280 bhp+ £2k ish? max + maybe £1500 for a decent G50?

Bargain in my book....!

Is there any argument for a 915 box instead of a G50 - I'm thinking ease of intall re Bug@5speed conversion parts etc, cost?

Any thoughts?

Martin has had customers with Subaru to 915 with much success.. PM us for details.. Do have a pdf (in german, that I can send you) with pics that may help on fitment.. PM email address if you would like..

Thanks, pm sent.

What are the differences between the two trans - size? strenght? fitment? ratios? etc.

Also, based on standard (ish) tyres, what are the revs / speed / gears numbers typically like?

I imagine that a Porsche trans will be pretty long legged?

It would be a fair bit more work to fit a G50, a 915 can just about squeeze in with the shorter nosecone but I believe it needs lowering to clear the bodywork. You want to go up rather than down wiht the Scooby sump/filter/exhaust depths.
I had a 915 with EJ20t in my speedster and it was OK but I wasn't a big fan of the slow shift (check the Porsche forums) so if I changed from the type 1 trans I'd go straight to a G50, no hesitation..

Fair enough, I guess that a short nose cone 915 still wouldn't give enough cam cover room without moving the box forward into the pan?

The scale of the work to fit a G50 doesn't really bother me. It's small change on the grand scale of a full body off resto with IRS conversion.

On a different note, just what is the performance like on a 250 - 300 bhp scooby bug like?

I've driven some very powerful cars in my time, just wondered how it feels?

LT, if you are looking for an occasionally driven car like you said, I would recommend just going for a built type 1. Itll be simpler in the long run, and will still make u mess your pants.

Also, curious why are you going for the g50?

"Sti Scooby 280 bhp+ £2k ish", + a couple K for the conversion. Sti engines arent cheap.

Hi

Ive fitted a G50 into my 1303, I have also moved it forward 100 mm right through the torsion bar housing. I went so far forward because the Subi motor im using has variable cams and they stick out a little more than other WRX motors and I also wanted better weight distribution.

Its not a conversion for the faint hearted.

A pro built 200 bhp type 1 motor with Porsche fan conversion and fuel injection is going to cost £6-7k.

I've seen several sti motors on UK ebay in the last few months all go for around the £2k mark.

To make a scooby / type one cost comparison fair, you'd need to compare to the cost of maybe an EJ20T or similar - many of these go for under £1k.

I like the idea of a Porsche box because of the 5 speed, and I also feel they would stand up to the duty cycle better tyhan a built type one?

I welcome any and all your feed back and comments?
